Sam Winchester

Samuel "Sam" Winchester is a hunter as well as a Man of Letters, partnered with his older brother Dean, and one of the leads of Supernatural. In addition to being Dean's younger brother, Sam is a descendant of Cain and Abel, the second son of John and Mary Winchester, the older paternal half-brother of Adam Milligan, the grandson of Samuel and Deanna Campbell and Henry and Millie Winchester, and the third cousin of Gwen and Christian Campbell. Early in Season 5, Sam is revealed to be the true vessel of the fallen archangel Lucifer, making him an abomination in the eyes of most celestial beings, with the exceptions of Castiel and God himself. He and Dean are also the honorary sons of Bobby Singer. Sam has had a number of flings in the show, although all of them have ended badly for him. Despite the relationships that he has had in the series, Jessica Moore was Sam's first love and he hasn't ever been able to fully get over her. Sam is friends with angel Castiel, prophet Kevin Tran, demon Meg, and often reluctant ally and enemy of demon Crowley. Sam also served as a vessel for the angel Gadreel before Sam expelled him. Both Sam and Dean were raised in the hunting life by their father after the demon Azazel killed their mother as part of John's quest to find and kill the demon responsible. Sam's initial main role in the series was being a reluctant hunter who dreams of having a normal life away from his over-baring brother. However, over time this has changed and Sam has embraced the lifestyle more, often going to great lengths in doing so. Sam started and stopped the apocalypse in Seasons 4 and 5, highlighting his selflessness and love for his brother.

Early Life
Sam Winchester was born on May 2, 1983 to John and Mary Winchester in Lawrence, Kansas. He is the couple's second child, four years younger than his older brother Dean. When Sam was only six months old on November 2, 1983, his mother, Mary, was killed in his nursery by the Yellow-Eyed Demon Azazel. Mary walked in on Sam's nursery while Azazel was feeding the infant demon blood. He has still kind of a psychic trauma due to this day and doesn't like Halloween.

Infant Sam is saved from the ensuing fire when his father takes him out of his crib and gives him to a four year old Dean, who then carries him outside while their father unsuccessfully tries to rescue their mother. Sam and Dean spent their childhood moving from town to town while their father hunted supernatural beings. Until he turned 8 years old, Sam believed his mother had died in a car accident and his father was a traveling salesman, until he found his father's journal and demanded Dean explain. Dean revealed to him the existence of the paranormal. When Sam was eleven he spent his Thanksgiving with another family. He remembers it fondly as it was (according to Sam) his first actual Thanksgiving, seeing as the other Thanksgivings he and Dean would have a bucket of extra crispy chicken while their dad would pass out on a couch. Sam started hunting alongside his brother and father around the age of twelve. However, he began to crave a normal life without monsters when a teacher of his, unaware of the whole story, encouraged him to seek alternatives to "the family business." On the 4th of July 1996 Sam and Dean snuck out to a field with fireworks where, according to Dean, they had burned the field down.

Dean frequently left Sam at Plucky Pennywhistle's Magical Menagerie before going to hang out with girls which is possibly a cause for Sam's fear of clowns. When Sam was about 15, John and Dean left Sam alone to hunt a Kitsune while Sam compiled the research for them so they could kill it properly. This is where he met Amy, who, unbeknownst to Sam, was the daughter of the kitsune John and Dean were hunting. Sam eventually learned his friend was a kitsune but decided to let her go when she had killed her own mother to save his life. At some point Sam ran away to Flagstaff, Arizona while Dean was watching him. He stayed there for 2 weeks and while he was there he took in a dog and called it Bones. Sam eventually went to Stanford University thus leaving his family. A year after that their father went looking for the thing that killed their mom. So Sam and Dean both went looking for him and that is when the hunting started.

Season 1
In much of Season 1, the Winchester brothers hunt down mystical creatures and urban legends like the Wendigo, folklore's Bloody Mary, and Shapeshifters. Although Sam's brother, Dean, has been mainly responsible for gathering hunting leads at this point, Sam's episodes of precognition and telekinesis soon direct them to where several of their hunts take place. At the start of the series, Sam is a senior at Stanford University who is applying for law school. Sam also has a girlfriend, Jessica Moore, whom he lives with and is secretly planning to marry. One night, Dean comes to Sam's apartment to seek his help after their father goes missing; although reluctant at first, Sam eventually accompanies his brother. After defeating the Woman in White and discovering a trail to find their father, Sam returns to Stanford. Upon his return, Sam witnesses Jessica's murder in the same style of his mother's, prompting him to embark on a journey with his brother to find their father and kill the demon responsible.

One of the first instances when Sam experiences precognition is in Home when he awakens from a vision of a woman screaming from the second story window of the Winchesters' old house. Afterwards, Sam insists they find out what's going on when Dean refuses until Sam gives him good reason. Reluctant at first, Sam eventually confesses that he "has these nightmares" during which he can foresee terrible events. This is also when Sam tells Dean that he had nightmares about Jessica's death days before it occurred. Dean initially dismisses his brother's abilities as coincidence and is overwhelmed with the idea of going home. In contrast, this is one of the many moments when Sam's desire to know the truth outweighs his emotions.

In Scarecrow, the tension between Sam and his father becomes clear when John calls Sam to tell him important information regarding a separate hunt. When Sam asks to know where John is, John insists that Sam "just does his job" and takes down some information, also saying that Sam and Dean are not allowed to help him in the fight against Azazel. Sam also displays increasing resentment towards Dean for unquestioningly playing the role of dutiful son to their father's requests. Once on the road, they begin discussing the hunt their father has asked them to go on when Sam confronts Dean about his loyalty to John. While Dean is persistent in learning more about the new hunt, Sam decides to go look for their father in Sacramento, California. During his journey, Sam runs into another lone traveler by the name of Meg Masters, a spunky blonde who takes an immediate interest in Sam. Although acquaintances, the two soon begin to develop a kinship due to their similar feelings of resentment towards their families. Later in the episode, it is revealed that Meg is in fact, a demon. Later, Sam and Dean reconcile when, to Sam's surprise, Dean praises his brother's ability to stand up to their father. When Sam tries to call Dean the next day, he tries for three hours unsuccessfully until he decides to go looking for him. Throughout this episode and especially during this moment, Sam displays a loyalty to his family unlike what is seen in Dean; While Dean is keen on following orders from John regardless of where he lands, Sam is more likely to go wherever he believes his family needs him, despite what anyone (family included) has to say.

Sam has another premonition in Nightmare when a man's murder is staged to look like a suicide. Dean is still reluctant to believe Sam's ability though this becomes another hunt that is determined by yet another one of Sam's visions. When the brothers arrive at the scene of the man's murder in Michigan, Sam becomes more perplexed with his ability and Dean begins to place more trust in Sam's premonitions. Throughout the rest of the episode, Sam continues to successfully predict the murders of innocent people. Later, the brothers learn that the murders have been at the hands of a troubled young man by the name of Max Miller. Here, Sam has a waking vision, a first at this point, of Max confronting his stepmother with a kitchen knife that will undoubtedly end in her murder. After learning of the man's troubled past, Sam's first impulse is to try and talk Max out of murdering his stepmother, insisting that they both share similar qualities. During their conversation, Sam learns that Max's real mother was killed years ago in his nursery while he was sleeping, which becomes the first time Sam has heard of another sharing his experience. Sam begins to wonder if there is a connection between his abilities and his own mother's death for the first time. This is also the first episode when Sam's ability to move objects is revealed when Max almost kills Dean.

In Shadow the brothers learn the real identity of Sam's old acquaintance friend, Meg Masters, when she plots to use the boys as bait for their father, John. This episode is also a good example of the contrast between Dean's "shoot first, ask questions later" mentality and Sam's more methodical approach to think things through; Upon learning the true identity of Meg, Dean insists they interrogate her right away when Sam suggests they learn who she's been having private meetings with first. Sam also expresses his desire to live a normal life "when this is all over", much to Dean's disappointment. "Dean, when this is all over you're going to have to let me go my own way." (Sam to Dean in "Shadow" 1.14)

Sam and Dean bust out with a bit of comic relief as they pull pranks on each other throughout Hell House. Otherwise methodical and often serious, Sam unleashes his more humorous side with antics like leaving Dean to start his Impala with the radio set to what sounds like Latin music on full blast and putting super-glue on Dean's beer. He also enjoys mocking the Ghostfacers (who make their first appearance in this episode) during their random encounters.

In Something Wicked, the audience sees their first peek into Sam's childhood, before he knew anything about "the family business". The viewer also begins to see a glimpse of the bond that exists between Sam and Dean as brothers. It becomes clear that Sam is the more pure and innocent of the two when he refuses Dean's suggestion to "dangle a kid like meat on a hook" in order to kill a witch. In the end, they decide to go through with the plan. It is learned during this episode that Sam was once almost killed by the very same witch they are hunting.

For the first time since Jessica's death, Sam finds romance with Sarah Blake, an art dealer's daughter, in Provenance. The brothers come across a murder in which a mysterious painting is the culprit and they must find out how to stop it from happening. Unwilling at first, Sam decides to take Sarah out for dinner as a means of gaining information about the painting. During their conversations, Sam takes a liking to Sarah despite his conflicting feelings of guilt. Later, Sarah becomes one of the first few women in Sam's life who learns about Sam and Dean's real line of work.

The brothers are reunited with their father in episode 20, Dead Man's Blood. John claims that a man named Samuel Elkins taught him everything he knows about hunting and that he needs his gun, the Colt, for some unknown purpose. The tension between Sam and John becomes increasingly clear when John insists they go after a nest of vampires in search of the Colt. En route to the vampires nest, Sam pulls to the side of the road and initiates and altercation with John, demanding to know where they're headed and why. An enraged argument ensues until Dean is able to separate the two. Later, Sam and John reconcile and resume their search for the Colt. After Sam and Dean prove their strength as hunters, John agrees to let the brothers help him in his fight against Azazel.

With every reason to believe they have a lead on Azazel and now armed with the legendary Colt, the three Winchesters head out to Salvation, Iowa in Salvation. When he learns more about his past and Azazel's habits from John, Sam begins to feel overwhelming guilt for the murder of his mother, Jessica, and the seemingly random families that Azazel is targeting. Sam has another waking vision of a family being attacked in the same fashion Mary and Jessica were killed, presumably because he was within walking distance of the home in which it is set to take place. Around the same time, Sam also tells John for the first time about his visions and nightmares.

Shortly thereafter, Sam receives a call from Meg asking to speak to John. They discover that she is the one responsible for killing John's friends and says she won't stop until she gets the Colt. From there, John leaves the brothers once again to pass off a fake Colt to Meg in hopes that she will cease the murders.

As Sam and Dean wait outside the home of the family who is about to be attacked, Sam makes sure to tell Dean "thank you for always being there. . . just in case." This shows that Sam truly values his relationship with his brother and the realness of their mortality when up against Azazel. This is also the first moment Sam outwardly expresses his appreciation for Dean as his older brother.



They end up saving the family, although they fail to confront Azazel as they watch his silhouette in the second story window of the burning home. Afterwards, Sam expresses immense guilt for not stopping the demon and anger towards Dean for not allowing him to run inside the house. At this point in the series, Sam has become more invested in the hunt for Azazel, showing more conviction than even John or Dean at times. When Dean tries to convince Sam there was nothing they could do to stop the Yellow-Eyed Demon, Sam goes into a rage and throws Dean against the wall. Dean pleads with Sam, saying that the three of them is all he has and that he refuses to let Sam die. Sam immediately realizes that John hasn't responded to their calls and demands they go looking for him again.

Devil's Trap begins where the last episode left off when Dean calls John only to hear Meg's voice on the other end. At this point in the season, Sam's regard for logic and reason seems to have gone out the window as he's become more careless in his thoughts and actions, and more obsessed with avenging the deaths of his mother, Jessica, and possibly his father's. However, Sam still struggles noticeably with the idea of exorcising Meg knowing that once he does, she will die from her wounds. Once she is exorcised and passes away, Sam once again assumes the role of astute researcher, looking for ways to outsmart their enemies on their trek to rescue their father.

When they meet up with John, Dean realizes that John is possessed by Azazel and is ready to fire the Colt when he and Sam are thrown against the wall. When Azazel challenges Sam to make the gun float to him, Sam is unable to use his ability unlike previously seen in Nightmare. However, it is during this episode when Sam begins to learn more about Azazel's plans for him "and all the other children" like him.

Once John is able to regain control of his body for a fleeting moment, the hold on the brothers is released. Dean is in bad shape when Sam grabs the Colt and shoots Azazel's vessel in the leg. Sam is soon thrown into a terrible dilemma when John yells for him to shoot while Azazel is still occupying his body. In the end, Sam is unable to kill his father and shots him in the leg causing Azazel to leave John's injured body and escape once more. The conflict that takes place in Sam's mind is evidence that despite his and John's past misunderstandings, his loyalty and love for his family is a bond not about to break, even if it means ending the hunt for the Yellow-Eyed Demon. On the contrary, John expresses his frustration with Sam for not shooting him when he had the chance.

The season finale concludes with Sam, Dean, and John leaving Salvation, Iowa when they become the victims of a horrific crash; While a very injured Sam is driving the Winchesters to the hospital, a semi-truck crashes into them, causing massive damage to Dean's Impala with the Winchesters inside. At this point in time, their fate is uncertain at best.

Season 2
In the first episode of this season, In My Time of Dying, Sam confronts the demon-possessed man who is responsible for the collision that occurred at the end of Season 1. The demon backs down and exits the man's body before the Winchesters are airlifted to a hospital in Sioux Falls, South Dakota. In desperation, Sam unsuccessfully checks to see if John or Dean are even alive. Later, John wakes and despite his wounds, Sam is able to move about the hospital. He is in pieces when he learns that Dean's injuries are life-threatening.

When Sam visits his father, John sends him off with a list of items he needs from Bobby. Although he is unsure of what John is planning to do, he soon finds out from Bobby that John is planning to summon a demon. Outraged, Sam once again jumping to erroneous conclusions confronts John about his seemingly lack of concern for the welfare of his family. During the altercation, a glass of water crashes to the floor which causes them to believe it could be Dean in an attempt to contact them from 'the other side'. Afterwards, Sam promptly falls into research mode and acquires a Ouija board in an attempt to confirm their suspicions.

Here, a part of Sam's personality is revealed to have more faith in peculiar methods of communicating with the dead and therefore appears to be more open-minded to certain devices that Dean might consider cliche. In addition, once Sam learns that a reaper is after his brother.

In the end, it is John's sacrifice that saves Dean rather than Sam's ingenuity. During the conversation between John and the Yellow-Eyed Demon, it is revealed that John knows "about Sam and the other children" like him.

Sam demands to know where John has been when Dean wakes up from his coma, to which John replies he was "out taking care of some things." Sam is ready to argue when John calmly insists he doesn't want to fight anymore. Puzzled at his father's sudden agreeableness, Sam leaves to get John a cup of coffee only to return to his father's body lying on the floor of John's hospital room. The final scene cements the looming and painful guilt Sam experiences for reacting defensively during his last moments with John.

Everybody Loves a Clown takes place roughly a week after their father's death. Sam shows his expertise with cracking codes for the first time in the series by gaining access to John's voicemail and tracing a message from a woman named Ellen. The brothers soon learn that Ellen Harvelle and husband William were once friends of John. They soon embark on a hunt involving murderous clowns who are possessed by demons. Sam's intense fear of clowns is first revealed in this episode.

Tensions between Sam and Dean beginning with this case when Dean questions Sam's quickness to jump on the case. Dean experiences resentment towards Sam, who now seems more willing to do what he thinks their father would have wanted him to do. At the end, Sam admits that what he is doing is too little too late.

"I miss him, man. And I feel guilty as hell. And I'm not alright, not at all. . . But neither are you." (Sam speaks about their father to Dean in "Everybody Loves a Clown")

In Bloodlust, Sam is put off when they meet a hunter by the name of Gordon Walker. Said hunter is Sam's diametrical opposite, seeing no shades of gray when it comes to hunting. This contrast is illustrated when Sam is kidnapped and then set free by a vampire named Lenore. When Gordon finds the vampires, he is ready to kill when Sam insists they are harmless to humans.

Sam delves deeper into the role of researcher and finds many of the brothers' leads. Sam begins to search for psychic children like him to find out Azazel's plan of which they are a part. Eventually Sam learns from Dean that before their father's death, John told Dean that Azazel is planning to turn Sam evil and that Dean must save him but if he cannot Dean must kill him. Although angered at his father and brother upon learning this revelation, Sam concludes to save as many people as possible so that he can change his destiny.

At the start of Hunted, Dean reveals to Sam what John said to him moments before his death.

''" He said that I might have to kill you, Sammy." ''

After finding out this, Sam is convinced that he must save as many people as he can in order to change his destiny, as he drunkenly states in Playthings.

In Born Under a Bad Sign, Sam is possessed by the same demon responsible for Meg's possession in Season 1. It is also hinted at that this is also the same demon that lead to the death of Ellen's husband. It becomes clear that if the time comes for Dean to shoot his brother, Dean would not be able to do so. In this episode Sam (while still possessed) also kills another hunter.

In the episode What Is and What Should Never Be, Sam and Dean are not close in the alternate reality created by a djinn. Neither Sam nor Dean had ever hunted, and Jessica is Sam's fiancee. As in reverse to reality, their mother is alive.

In All Hell Breaks Loose Part 1, Sam is transported to an abandoned town along with Azazel's other chosen children. There he learns Azazel's plans: he and the other children will kill one another and the last one surviving will lead a demon army. Sam also discovers the reasons behind both Jessica and his mother's deaths; Jessica was killed because her death would lead Sam back into hunting. As for Sam's mother, it is revealed Mary interrupted Azazel during the process of feeding Sam demon blood, and thus was killed. It is also revealed that Mary knew Azazel prior to the attack in Sam's nursery. It is revealed in a later episode that Azazel had killed John in the past and made a deal with her to resurrect him in return for access to her house in the future. He then wipes her memory so that she does not remember this. Although Sam tries to protect the other children, various fights ensue, and the children are killed off one by one. Eventually, only Jake Talley and Sam are left, at which point Sam is stabbed by Jake and dies in Dean's arms.

In All Hell Breaks Loose Part 2, Sam's body is now at Bobby's, a broken Dean is stood watching over him. Dean doesn't want to bury Sam despite Bobby trying to convince that it's for the best. Desperate and depressed, Dean speeds off in the Impala to the crossroads where he sells his soul to the Crossroads Demon in return for Sam's resurrection. Sam wakes up at Bobby's confused as to what has happened. In pain, Sam looks in the mirror at the marks on his back before Dean returns and bundles him into a hug. Sam is determined to track down Jake straight away, but Dean convinces him to take it slow. While they are eating, Sam and Dean discuss the events that took place. Sam states that he only remembers seeing Dean running towards him then a white hot pain in his back. With the help of fellow hunters Bobby Singer and Ellen Harvelle, Sam and Dean track down Jake, but are unable to stop him from opening a gateway to Hell on Azazel's orders. However, Sam shoots Jake and kills him in cold blood. After the gateway is closed and Azazel is finally killed by Dean, with assistance from John who escaped from Hell, when Sam learns that he was dead and Dean sold his soul to bring him back, Sam promises Dean that he will save him no matter what it takes.

Season 3
As Sam continues to do whatever he can to save Dean from going to Hell, he begins to become more ruthless and is willing to kill anything demonic even if his prey is part human, human witches. Sam later reveals that he is trying to become more like Dean who is more willing to kill human enemies. This reasoning is Sam's view that if he fails to save Dean's soul he must be ready to face a world full of demons on his own.

Sam also meets a female demon called Ruby who has been trying to gain Sam's trust by helping the brothers through various methods such as fixing the The Colt, saving them numerous times, and lastly telling Sam she can save Dean from Hell even though in reality she can not. Ruby also reveals that because Sam refuses to lead the demon army, another demon, named Lilith, has fixed the power vacuum and is leading the army while carrying intentions to kill Sam; she is also revealed to hold Dean's contract to his soul. Season 3 focuses on Sam taking a much darker tone than he had had previously, while he desperately tries to find a loophole in Dean's deal. He picks up the broken Colt and with help from Bobby and the mysterious Ruby, fixes it.

Dean is trapped with a lustful demon, causing Sam to come to his rescue. As a race unfolds, the demon calls forth help. Sam is well aware of this too. As the seductive demon breaks free due to help, Sam is forced to kill one of them with the refurbished Colt. As Sam is about to pull the trigger on the Casey, Dean pleads for him to stop. Too late, Sam fires, killing her. Now, more determined to free Dean, Sam summons the Crossroad Demon and forces it to let Dean out of his deal. The Demon tells Sam that shes just a "sales woman" and that she has a boss. At point-blank range, he kills the demon with the Colt.

Deeper into the season, Sam is pitted against Gordon Walker. A rapid confrontation turns into the death of Gordan after he's turned into a vampire. Cutting his head off, Sam feels no remorse for killing him. Again he shows his dark side in the episode Jus In Bello when Ruby said she needed a heart of a virgin to kill the demons and banish them from the building and Dean did not want to do that, Sam actually wanted to help Ruby. In this episode, we also discover that Sam, as well as Dean, has a pentagram tattoo on the left side of his chest to prevent being possessed. He must have had this tattoo done between Season 2's Born Under a Bad Sign and Jus In Bello.

In the Season Finale, Dean is down to 30 hours and Sam suggests they summon Ruby. Not trusting her, they take her knife and head for Indiana where they find out Lilith is located. After many attempts to try to kill Lilith, the brothers fail. Dean discovers Lilith is possessing Ruby's previous body and sends Hell Hounds after him. A crying Sam pleads Lilith to stop. After Dean is dead, Lilith shoots a "burning white light" at Sam but he is left unharmed as he is immune. After that, Lilith is scared that her powers do not work on him and leaves after Sam attempts to stab her with Ruby's knife. He picks up the body of his mauled brother and cries out to him.

Season 4
After Dean's death, Sam has cut off all contact with Bobby. Even still, he tries several methods on trying to bring Dean back including making a deal with the cross-road demon. Still looking for a way to revive his brother, he lodges in Illinois, close to where his brother is buried. After a resurrected Dean reunites with Bobby, the two go to visit Sam. They find him with a girl, enjoying his "wild side." The girl is actually Ruby, a fact Sam immediately hides from Dean. Now trying to find information on who saved Dean, their search leads them to a diner where they meet demons who claim they know who broke Dean out. Dean, obviously knowing it's a bluff, slaps a demon twice in the face, gets up and nonchalantly leaves. Sam, however, tells Dean that they are demons and they need to die or other people will. Dean protests against this. Later, Sam returns to the diner to confront the demons. As he enters, he is attacked but realizes that the demons have had their eyes burned out. He calls forth Ruby to see if she has found anything. As the two discuss, Sam shows that his powers have developed and he is able to exorcise demons using his powers. Sam hides Ruby's involvement as well as his psychic powers from Dean, going so far as to deliberately lie and deceive him to keep Dean from finding out what he's up to. Sam helps Dean defeat the spirits of Agent Henriksen and Meg Masters in Are You There God? It's Me, Dean Winchester. Sam's powers rapidly develop, with guidance from Ruby in Metamorphosis, but Dean finds out Sam is using them. At the end of the episode, Sam decides to stop using his powers.

In It's the Great Pumpkin, Sam Winchester, Sam is able to exorcise Samhain. He also finally meets the angel Castiel. In I Know What You Did Last Summer, Dean finally gets an explanation of what happened to Sam and Ruby in the four months he was gone. Shortly after Dean's death, Sam has summoned the Crossroads Demon, hoping to switch places with Dean, but was promptly rebuffed. Ruby returned shortly after and, "betraying" Lilith, saved Sam. The pair had sex at least once, and Ruby began helping Sam develop his powers, eventually going so far as convincing him to drink her blood to strengthen him. Sam, along with Dean and Ruby, protected Anna Milton, when Castiel and Uriel arrived and demanded the girl be turned over to them to be killed. It is revealed in On the Head of a Pin that Sam drinks demon blood to fuel his powers. He eventually kills Alastair after Dean fails to interrogate him. It is revealed in The Rapture that he is now addicted to demon blood, but continues to drink it in spite of this. During Lucifer Rising it was revealed that Sam had been manipulated by Ruby the entire time. Sam succeeded in destroying Lililth, and by doing so, the demon blood turned him into a demon. Dean and Castiel tried to warn and later stop him, and as a result, Lucifer was released from his prison.

Season 5
Due to Sam breaking the last seal, and setting Lucifer free, Sam became a demon. God transported Sam and his brother onto a plane, saving them, and turning Sam human again. In the direct aftermath of freeing Lucifer, Sam tries desperately to redeem himself by trying to stop the devil’s plans. However, realizing that he is a liability in battle, Sam and Dean separate temporarily after and Sam has another attempt at a normal life until he is approached by Lucifer, in the form of the deceased Jess. Lucifer tells Sam that he is his true vessel, in conjunction with Dean being the archangel Michael's true vessel. Dean and Sam reunite shortly after this and Sam does his best to rebuild his relationship with his brother although the brothers are no longer as close as they once were because of his betrayal and find it hard to reconnect. That fact alone was emphasized in "Dark Side of the Moon", when Sam’s version of Heaven was completely devoid of his family and involved incidents that happened while he was away from the Winchesters, which causes Dean to discard the amulet Sam gave to him years prior. Dean is discouraged by Sam's different views of what Heaven is. In "Point of No Return", Sam takes the information he learned from his experience in Heaven and puts all his trust and faith in Dean, who admits he doesn’t believe in Sam and is convinced Sam will say “yes” to Lucifer at some point. However, Sam is shown to still have faith and belief in Dean and it is this faith that stops Dean from saying “yes” to Michael.

Sam still lives with the temptation for demon blood. In "Good God, Y'all", when Sam kills two humans who he thought were demons, he looks at the bloodied knife with slight wonderment. In "My Bloody Valentine", Sam is affected by Famine's ability and he attacks and drinks from Famine’s henchmen, becoming strong enough to exorcise five demons at once and eventually defeats Famine. However, he gets the blood out of his system as soon as possible at Dean's urging, and is returned to Bobby's panic room. Sam also admits that he is angry all the time although he is unsure as to why, a trait that Lucifer tells him he will need when Sam finally agrees to be his vessel. It is revealed in "The Devil You Know" that Sam's good friend from Stanford, Brady, was possessed all that time and Sam has been manipulated by demons even back then. Brady taunts Sam that perhaps the reason he is so angry and so easily manipulated by demons is because of all the demon blood inside of him and because he is just like them. Sam does not deny this, but acknowledges this as an 'interesting theory'. After discovering that Lucifer can be locked back into Hell using the rings of the Four Horsemen of the Apocalypse, Sam considers allowing the Devil to possess him in order for Sam to push him back into Hell. He discusses it with Bobby, who is at first very irritated by the sudden plan, but comes around to his way of thinking by "Two Minutes To Midnight" when there is clearly no other choice. When Dean finds out, he argues with Sam that he cannot do it, but later gives in to his plan, as it seems to be the only option left. Sam makes Dean promise not to try and bring him back from the cage, as that is too risky.

In "Swan Song", Sam finally says yes to Lucifer, prior to which he consumes gallons of demon blood to strengthen his body. Lucifer appears to take full control of Sam and starts a number of natural disasters around the globe. He also gathers all the remaining minions of Azazel who have been keeping watch over Sam his entire life. Lucifer informs Sam that they were always meant to be this way, two parts of the same whole and that Lucifer is Sam's true family. Sam strongly protests, and insists that he's going to "rip him apart from the inside out".

Lucifer meets Michael in the chosen area for the final battle, during which he (in Sam's body) kills both Castiel and Bobby and severely injures Dean. However, Dean tells Sam that he's there for him and after glancing into the Impala, Sam's memories return long enough for him to briefly take control of his body again. Sam opens the gate to Lucifer's cage, and despite showing apprehension at jumping, he prepares to jump in, but is interrupted by Michael, who asks for Sam to stand back and let him fight Lucifer. Sam refuses and falls into the cage, pulling Michael in with him, effectively stopping the Apocalypse. Sometime later, Dean accepts Sam's final request, to find Lisa Braeden and live a normal life, and sits down with them in their home. However, just outside the window, unseen by Dean or Lisa, Sam stands watching them.

Season 6
Sam wakes up mysteriously out of the cage and tries to get answers from Castiel with no results and searches for weeks, even going to Bobby for help. He eventually goes back to hunting, choosing not to contact Dean. Sometime along the way, he encounters a group of hunters from his mother's side of the family, including Samuel Campbell, who was thought to have been killed in 1973 by Azazel. Soon, Sam goes hunting for djinns and discovers that they're going after Dean next. Sam gets involved when the djinns nearly kill Dean. This allows him to reunite him with his brother, and he's forced to tell Dean that he's been back nearly the entire time since he jumped in the cage and that he chose not to tell Dean because Dean would leave his "normal" life behind if he did. Dean gets angry at Sam (and later at Bobby, as he knew of Sam's return as well). Then Sam introduces Dean to their third cousins and grandfather from their mom's side, after whom Sam was named. Sam and Dean take Lisa and Ben to safety at Bobby's until they take care of the djinns. The djinns attacked the brothers, and they're nearly killed but are saved by Samuel and the others. Later, Dean decides not to return with Sam and to stay with Lisa and Ben. He offers Sam the Impala, but Sam declines.

Things get stranger between Sam and Dean, as Dean starts to notice that Sam has been acting differently ever since he came back into his life. Sam uses a baby shapeshifter as bait to draw in the Alpha, stands aside when Castiel tortures a kid for intel on the angel buying souls (Balthazar), he even lets Dean get turned by a vampire to get more information on the Alpha Vampire. When Dean confronts Sam about it, Sam, however, lies and says he "just froze". When the brothers are held captive by the Goddess of Truth, Veritas, in You Can't Handle the Truth, the goddess reveals that there is something wrong with Sam. Sam tells Dean that he's still Sam, but he knows something's wrong with him, and he admits at Dean's urging that he might need help. Dean responds by beating Sam unconscious and calling Castiel for assistance.

Upon inspection, Castiel determines Sam is physically healthy but his soul is missing. Dean plans to keep Sam tied up, but Sam sets himself free and convinces Dean to work with him. Later, Sam and Dean meet up with Samuel, who informs them that he's got a lead on the Alpha vampire. But when Dean sees Sam walking the vampire into a van, he confronts Sam, and Sam states that Samuel needs to interrogate the Alpha. Sam helps Dean find out where Samuel is taking the creatures for interrogation and question the Alpha vampire about Purgatory. But when the Alpha breaks free and attacks Sam, Christian reveals himself as a demon and teleports the vampire away. Crowley then appears on the scene, and claims to be the one who raised Sam from Lucifer's cage, and the one in possession of his soul. He tells them that if Sam ever wants it returned, he and Dean need to help Samuel capture creatures for him.

Sam's behavior, however, shows that he is definitely conflicted over whether or not he actually wants his soul back. He tries to convince Dean that he is still the same Sam. He works Crowley's cases without question and claims that his brain works better than ever. But his actions contradict this, as when dealing with a skinwalker case in All Dogs Go To Heaven, Sam orders Dean to take a shot at the pack leader, even when there is an innocent in the way. Sam later comes clean to Dean about himself. He admits that he's not the old Sam and that he doesn't even care that much about Dean, besides the fact that he needs his help. He also says he's done a lot worse than Dean's aware of, including killing innocent people when they get in his way. After some thought, Sam reluctantly tells Dean he should probably go back to being the old Sam and get his soul back. Dean acknowledges this.

In Clap Your Hands If You Believe,  Sam confronts a leprechaun, who offers a deal to lift Sam's soul from the cage. Sam expresses curiosity, but banishes him and the other fairies. When asked by Dean why he refused, Sam suggests that deals have never lead them anywhere good. Dean then questions whether Sam is having second thoughts, which Sam denies with a simple "No."

Sam and Dean continue to work for Crowley in Caged Heat, despite Dean's remarks about them not getting anywhere. The brothers are unexpectedly captured by Meg, who wants them to give her Crowley's location. Sam makes a deal with her: they will give her Crowley if she promises to torture Crowley to get him to give Sam back his soul. He then calls Castiel to join the group for searching for Crowley. Samuel gives the party the location, but once inside Crowley's prison, Sam and Dean are captured by Crowley's demons, as the two have been sold out by Samuel. The two are put in separate cells, and while the demons take Dean away to have him killed by ghouls, Sam escapes his cell and saves Dean. The brothers confront Crowley and Sam demands his soul. When Crowley refuses, Castiel burns the demon's bones. Dean tries to reassure Sam, but Sam tells him that he does not think he wants his soul back after all.

In Appointment In Samarra, Dean informs Sam and Bobby that he has made a deal with Death that could result in Sam getting his soul back. Death will put up a "wall" in Sam's head to protect him from the memories of Hell. Bobby is given the job of watching Sam while Dean does Death's job for a day. But Sam slips Bobby's watch to summon Balthazar. He asks Balthazar for a way to keep his soul out of his body and Balthazar tells Sam that he has to make his body uninhabitable for his soul by committing patricide, so Sam resolves to kill Bobby. Bobby realizes what Sam is up to, however, and manages to drop Sam into the basement. Sam again finds a way to escape, and when Bobby goes outside to look for him, Sam knocks him out from behind. He ties Bobby to a chair and prepares to kill him, but Dean shows up in the nick of time and knocks Sam out. Sam wakes up chained to the bed in the panic room and Death shows up to restore Sam's soul to his body, with the latter screaming in pain. Sam (his soul) spent approximately 180 years in Hell.

Sam wakes up about a week later in Like A Virgin, with no apparent memory of Hell or even his year without a soul. He is emotional, sensitive, and full of life, much unlike "RoboSam." He questions Dean on a number of occasions, as to how he got back, and if he even tried to live a normal life. But after a while, Sam starts to have feelings of deja vu. And when Dean and Bobby both remain tight-lipped, Sam tricks Castiel into filling in the blanks of his year being soulless. After getting rid of a couple of dragons, Sam apologizes to Dean about all he's done, feeling guilty and expressing a will to set things right. He is apparently not angry, but grateful about Dean trying to protect him. However, he wants to know what he did while he was soulless. Dean does not divulge any details, knowing the risk of Death's wall crumbling.

In Unforgiven, Sam tries to catch up on the year he was "gone." He receives a mysterious text from an unknown number, giving coordinates to a small town where three women have disappeared in the last week. Upon arriving, Sam already begins to have flashbacks of his time there, and remembers that he used the sheriff as live bait to track down an Arachne. Upon finding the Arachne's lair, he killed it, then shot all of the captive men (including the sheriff). But it turns out the sheriff didn't die and is now an Arachne himself. Sam manages to decapitate him and, feeling guilty, agrees that they shouldn't have come to town. As he wonders about what else he could've done, he collapses on the floor and has a flashback of himself burning in Lucifer's Cage. He is out for a whole minute before waking up, but Sam tells Dean that it felt like a week had passed by.

Later, Sam, Dean, and Bobby all track leads for the Mother of All Monsters, Eve. They team up with an old friend, Rufus Turner, and run into Gwen and Samuel. Samuel notices the difference in Sam, who he only knew when he was soulless.The team of hunters realize that what they are hunting is a Khan Worm that takes possession of a person's body and kills anyone around them. It first possesses Dean, who shoots Gwen. Then possesses Samuel, who is shot by Sam. A possessed Bobby kills Rufus, and is later knocked out by Dean only to be interrogated and almost killed.

In Frontierland, Sam remembers the Campbell Compound had a hidden library, where they might be able to find something about killing Eve. Dean finds Samuel Colt's journal, where he reads that Colt killed a phoenix. He suggests a plan to head back in time and bring back the ashes. Castiel sends them to 1861 and Sam finds Samuel Colt, who is retired, but gives him the Colt, which Dean uses to kill the phoenix. They return before they can grab the ashes, but a delivery was made to Sam from Colt himself, containing his broken cell phone and the ashes.

In Mommy Dearest, Sam, Dean, Bobby, and Castiel head to Eve with the ashes. They find out that Eve is currently populating the small town with new monsters. However, once the boys confront Eve (who has taken their mother's form), she proposes an offer: to bring her Crowley, who is apparently alive, and she will let the group live. Dean protests that they don't work for monsters and persuades Eve to bite him, and Eve is killed after  discovering phoenix ashes in Dean's bloodstream. Sam and Bobby suspect that Crowley faked his death, and that Castiel purposely meant to burn the wrong bones.

Dean tries to remain loyal in The Man Who Would Be King, and argues in favor of Castiel, but Sam and Bobby remain suspicious. Castiel gives himself away, however, and the three trap Castiel in holy fire to interrogate him. Not only does he confirm his alliance with Crowley, but he reveals to Sam that he was the one who freed Sam from Lucifer's Cage, not Crowley.

In Let It Bleed, Castiel arrives at Bobby's place to try to explain himself and Bobby notices that he stole a journal that suggested that horror writer H.P. Lovecraft had attempted to open a door to Purgatory. Ben calls Dean to tell him that men are coming for him and his mom after killing her boyfriend. Crowley then takes the phone and gives him the warning to back off in order for Lisa and Ben to keep breathing. Sam and Dean summon Balthazar for help on finding Lisa and Ben, and they manage to rescue them from the demons. Once in the hospital, Dean asks Castiel to wipe their memories of him.



In the season finale, The Man Who Knew Too Much, Sam is stuck in his own head after Castiel brings down Death's wall. He runs into the soulless version of himself and kills him, which gives him the memories of his soulless year. Sam then arrives at a grim facade of Bobby's house, where he finds the version of himself from Hell. The Hell Sam pleads for him to remain unconscious and ignorant, but Sam insists on putting himself back together because he can't leave his brother out there alone. He stabs and integrates with his other self, now remembering Hell. Sam wakes up and continues on to Crowley's headquarters, where he sees an overpowered Castiel return to destroy Raphael. Sam picks up an angelic blade and stabs him in the back. But Castiel simply pulls the weapon out and says the blade won't work because he is not an angel anymore. He proclaims himself their new God, and gives them the choice to either venerate him or be killed...

Season 7
Soon after Castiel leaves, Sam begins to suffer from his memories of Hell, and passes out. He later awakens in Bobby's house and helps Dean fix the Impala. Although Sam is still plagued by the memories of Hell, he does not share this with Dean, intentionally withholding the information from him. They come up with a plan to bind Death to stop Castiel, but it fails when Castiel stymies them and unbinds Death. While helping Castiel get the souls back to Purgatory Sam begins having hallucinations of Lucifer telling him that Sam had never left the cage and his excursion into the real world was merely a form of torture created by Lucifer. Dean snaps Sam out of his hallucinations long enough for them to find the Leviathans which had guided Castiels' vessel to water allowing the Leviathans to escape and contaminate the water supply.

Soon after Sam tells Dean and Bobby about his flashbacks and hallucinations. Knowing he has a problem Sam decides to stay behind on hunts. He is soon tricked by Lucifer, and brought to a warehouse by him where he is manipulated into almost shooting Dean. Dean manages to snap Sam out it using the pain from his scar, and they return to Bobby's. There they find it in ruins and Edgar waiting for them. Sam is knocked out, but Bobby manages to save him at the hospital.

In The Girl Next Door, he notices a case that he worked when he was a teenager. He leaves Dean without giving him any information and takes the Impala to track down the clues. He eventually finds Amy again, and asks her why shes killing again. She tells Sam she has a son, and he needed the live meat. After she assures him that she will not kill again, he lets her live. Returning to the motel room, he meets with Dean again. He tells Dean about Amy, and asks Dean to trust him.

In Defending Your Life, Sam and Dean are hunting Osiris who is putting the guilty on trial. Sam puts his old pre-law skills to use in attempt to save Dean's life.

However, in Slash Fiction, it is revealed to Sam that Dean had killed Amy behind Sam's back, and Sam is furious. This causes him to storm off and separate from Dean for a week before they are reunited in Lily Dale. Sam is still angry with Dean, but grudgingly works on the case with him. They figure out that Jimmy Tomorrow has Marget Fox's Bones. Sam tries to reason with Jimmy without any luck and is forced to shoot Jimmy. Sam burns the bones and later makes up with Dean and they hunt together again.

He, Dean, and Bobby find out that its a Leviathan plot, but Bobby is murdered by Dick Roman before they can stop it. In Death's Door, Sam is holding memories of hell at bay using the scar. Sam is worried for Bobby, but readies himself for the worst. As they say goodbye, Bobby wakes up and writes numbers on Sam's hand before dying. He and Dean mourn the loss of Bobby in their own way.

In Repo Man, Sam allows Lucifer's hallucination to help him find Jeffrey who had taken Dean hostage. After helping him however, Lucifer reappears. Sam tries to make him go away by causing pain to himself through his scar but to no avail. Lucifer tells him that by allowing Lucifer to help him, he had in turn given Lucifer a firmer grip on his mind. In The Born-Again Identity, Sam is admitted into a psychiatric ward after he had a full blown psychotic episode with Lucifer. Sam is unable to sleep and is on the verge of death before Dean brings Castiel who is reincarnated and using the name Emmanuel. Castiel is unable to cure Sam but is able to transfer his hallucinations to his own mind. Sam gets back his sanity at the cost of Castiel's.

In Party On, Garth, it is revealed that Sam tried to use the ouija board to contact Bobby's spirit. He didn't tell Dean because he didn't want to drag him in, and admits that he didn't contact anything.

In the final moments of Survival of the Fittest, after Dean kills Dick and disappears, Crowley explains to Sam that he is "well and truly on his own". Crowley then leaves with Kevin Tran and Sam is left alone in the building looking lost and confused and completely in the dark about where Dean is...

Season 8


In season 8, Dean returns from Purgatory with the help of a vampire named Benny. Dean calls Sam to meet him and two of them share a hug. When Sam asks about Castiel, Dean implies that he died in the attempt to escape Purgatory. When Dean asks Sam what has happened in the year since they last spoke, Sam tells him truthfully that he has not hunted for a year and was in a relationship with a woman named Amelia. He admits to Dean that he didn't look for him during the past year because he thought he was dead. And this puts a strain in their relationship, as Dean feels betrayed.

A few episodes later, in Blood Brother, Sam finally meets Benny, and becomes extremely jealous of his relationship with Dean. He also feels hurt that Dean has a friendship with a vampire when he killed Sam's friend Amy for being a monster just the year before.

Sam's distrust of Benny worsens when a trail of vampire kills leads right to where Benny has settled down in Citizen Fang. At Dean's behest, Sam agrees to give Benny the benefit of the doubt, but Martin Creaser becomes adamant that Benny is the one behind the deaths. Dean sends Sam a fake S.O.S. text from Amelia to get him out of the way, and while Sam rushes to the rescue, an innocent Benny is forced to kill Martin in self-defense.

Sam finds out that Dean faked the text in Torn and Frayed, after he discovers that Amelia is perfectly unharmed. But she admits to Sam that she still loves him, and will be with him if he wants to stay with her. Sam takes a few days to consider her offer, and helps Dean and Castiel rescue an angel named Samandriel from Crowley in the meantime. Dean tells Sam that he will give him his full blessing if he decides to stay with Amelia, but Sam realizes that he'd rather be with his brother. He chooses to stay with Dean instead of meeting up with Amelia at their rendezvous point.

In As Time Goes By, Sam and Dean meet their grandfather, Henry Winchester, and help him take down a demonic Knight of Hell named Abaddon. The key Henry died protecting leads them to the MOL headquarters, and after further research and working a case with the Juda Society, Sam takes up the throne as the next "legacy" and becomes a Man of Letters.

Kevin finally manages to decipher the demon tablet in Trial and Error, and using Kevin's translation of the Word of God, Dean convinces Sam that he should be the one to attempt the trials to shut Hell's gates. But while trying to save Dean's life, Sam ends up killing a hellhound, thus fulfilling one of the requirements of the tablet.

At the end of Man's Best Friend With Benefits, the effect resulting from the trial is revealed, as Sam begins to cough up blood, hiding it from his brother even though he seems visibly shaken. In Remember The Titans, we see Sam coughing up more blood and still hiding it from a suspicious Dean. Sam finally opens up to his brother when confronted, saying that he feels the trials are changing him.

While working on a case in Goodbye Stranger, they run into Castiel and discover that Crowley has been searching for Lucifer's crypt, seeing as it contains the angel tablet. They also discover that Crowley has been torturing Meg for information, as she knows the true whereabouts of the crypt's location. They rescue Meg, and she takes them to the crypt, but Dean insists that Sam stay outside while he and Castiel look for the tablet. Sam declares that he feels fine, but Castiel tells him that the effects of the trial have damaged Sam in ways that not even he can heal and that they've changed him on a "subatomic level". Meg and Sam discuss the year he spent with Amelia, and Meg tells him that she understands his desire for a normal life and a relationship. She is then killed by Crowley while trying to protect Castiel. At the end of the episode, Sam and Dean have a heart to heart, promising not to lie to each other and Sam agrees to let Dean help 'carry' him.

In Taxi Driver, Kevin translates the second trial as needing to "rescue an innocent soul from Hell". After meeting up with a rogue reaper named Ajay, Sam and Dean discover that Crowley had secretly sent Bobby's soul to Hell, and Sam goes with Ajay to try and rescue him. Both brothers quickly realize that Ajay's way to Hell is through Purgatory, and Sam experiences firsthand what his brother went through the last year while Dean desperately asks Benny to help him save Sam from Purgatory. Benny agrees and Dean kills him, planning to have Sam bring Benny back to Earth when he does the same with Bobby. Sam finds and rescues Bobby from Hell, and they both run into Benny, who saves their lives from a monster attack. Benny leads them out of Purgatory, but chooses to stay behind, claiming that he didn't fit in with the humans on Earth. Sam and Dean send Bobby's soul to Heaven, and Sam reveals how Benny chose to stay dead. Sam admits to Dean that he was wrong about Benny, and that he was a good person after all. Dean chooses not to burn Benny's bones, in the hope that he might bring him back someday, and Sam agrees with the decision.

Sam continues to get sicker and sicker from the trials, and becomes convinced that he won't get better until he finishes them. Crowley captures Kevin in The Great Escapist, and leads Sam and Dean to believe that he is dead. They go off looking for a way to translate the third trial by themselves, and run into an angel named Metatron. Metatron reveals that he was the scribe of God and the original author of the tablets before he went into hiding on Earth. Sam and Dean convince him to rescue Kevin from Crowley, and he tells them that the third trial requires them to "cure a demon".

In Clip Show, Crowley becomes nervous that the Winchesters might succeed in closing Hell, so he starts killing off all the people that Sam and Dean have saved in the past. Meanwhile, Sam and Dean decide to dig up Abaddon and try to cure her to finish the trials. But once they revive her, Crowley calls them away and she manages to escape. With no demon to cure, Sam and Dean go after Crowley, but Crowley explains his plan and threatens to kill Sam's old fling Sarah Blake if they don't give up the tablet. Sam and Dean do everything they can to protect her, but can't manage to save her life in time. And a grieving Sam starts wondering if they should give in.

In the season finale, Sacrifice, Crowley threatens to murder Jody Mills, and Sam and Dean agree to give up the trials in order to save her life. They arrive to make a deal with Crowley, but capture him with some of the bunker's demon-proof handcuffs, revealing that they are planning on using him for the third trial since Abaddon has escaped. They lock Crowley down in a church and Sam begins the process of curing him, injecting him with Sam's human blood once every few hours. Dean is called away to help Castiel in his attempt to shut the gates of Heaven, and Sam is left to finish the ritual alone. He notices that Crowley becomes more and more human as the night goes on, and Crowley finally admits to Sam that he just wants to be loved. They are interrupted by Abaddon, who is planning on killing Crowley and taking over Hell, but Sam manages to set her meatsuit on fire, seemingly killing her. Meanwhile, Dean finds out that the third trial will result in Sam's death and orders Castiel to return him to the church. He arrives just in time to stop Sam from completing the trial, explaining the consequences. But Sam replies that he doesn't care and he thinks closing the gates of Hell is worth him dying. He explains that he feels like all he does is let his brother down, and admits how hard it's been for him to see Dean turn to Benny and Castiel this past year instead of him. Dean tells Sam that he'd never put anything or anyone in front of him and that Sam is the person he cares about more than anyone else in the world. He asks Sam to stop the final trial, claiming that they can do more good as a team. Sam agrees and they embrace, but the effect of the trials doesn't subside and Sam cries out in pain. Dean helps Sam outside and they witness all the angels falling from Heaven, as Metatron has tricked Cas into unknowingly helping him complete a spell. They watch the angels fall as Sam succumbs to the effects of the trials...

Season 9
At the start of season 9, Sam is in a coma as a result of the trials. In his mind, he is starting to give up and considers letting himself die. His desire to live and his desire to die manifest themselves as images of Dean and Bobby, respectively, and they fight amongst each other in his head. Sam finally agrees with Bobby and apologizes to the vision of Dean in his head, saying goodbye. He comes face to face with Death, who tells Sam that he has come to collect him personally, and Sam asks him to make sure that his death is permanent this time. Meanwhile, in the real world Dean has asked an angel named "Ezekiel" to help him cure Sam. Ezekiel tells Dean that the only way he can save Sam's life is if Sam allows him to possess his body. Dean realizes that Sam would never agree to such a thing, and in a moment of desperation agrees to help Ezekiel trick Sam into saying yes. Ezekiel shows up in Sam's head, disguised as Dean, and begs Sam to live so they can stay together. Sam agrees, and Ezekiel possesses his body. He promises Dean that Sam will never know he's hiding inside him, and that as soon as he's healed Sam he'll leave.



In Devil May Care, Sam is still unaware that he's harboring an angel, and is surprised to find out that Dean left Crowley alive. Dean argues that Crowley can help them track down all the demons on Earth, and him and Sam lock him up in the bunker's dungeon. They receive word that Abaddon is still alive and is kidnapping hunters, so they go on a rescue mission. During the hunt, Sam is overpowered by three demons and Ezekiel takes over, destroying all of the demons and causing Abaddon to flee. Ezekiel stabs all three of the corpses with Ruby's knife, so that he and Dean can maintain the illusion that there aren't any angels involved. When Sam wakes up, Dean tells his brother that he was the one who defeated all the demons. And Sam relays how impressed he is at Dean's skill. Later on, Sam recovers at the bunker and reveals to a guilty Dean that he feels a lot better about his life now than he has in a long time.

In I'm No Angel, Ezekiel takes over Sam halfway through a conversation to reveal to Dean that angels are chasing Castiel. Dean tells Ezekiel that he doesn't want him popping up without any warning and that he'd rather handle things with his brother. Sam and Dean try to reach Castiel before the angels can get their hands on him, but run into a dead end. Worried for Castiel's safety, Dean asks Ezekiel to locate him, and they manage to find him just as a rogue reaper stabs him through the chest. Dean kills the reaper, and Ezekiel uses his powers to bring Castiel back to life. Sam and Dean bring Castiel back to the bunker with them, and Sam wonders how Dean was able to find their friend in time. Dean comes up with an excuse to pacify his brother's curiosity, but Ezekiel takes over and admits that he can't stay in the same place as Castiel since he's a target for dangerous angels. He tells Dean that if he doesn't kick Castiel out of the bunker, he'll have to leave and Sam will die. And Dean is forced to send Castiel away in order to save his brother's life.

In the following episodes, Dean continues to hide Ezekiel's presence from Sam, coming up with cover stories to explain away the discrepancies that Sam is starting to notice more and more. Ezekiel also heals Sam a number of times, saving his life from fatal injuries and healing Dean's friends whenever they are in danger. But after every use of his power, he tells Dean that each time means longer that he'll have to stay inside of Sam to recharge.



In Rock and A Hard Place, after encountering the goddess Vesta, she tells Sam that his organs are completely burned and that he's nothing but "duct tape and safety pins inside." Sam is worried by her statements and tells Dean that he feels like something has been wrong with him lately. He says he feels like he can't recharge his batteries and that he's always tired. Dean tries to pass the symptoms of Ezekiel's presence off as a lingering effect of the trials, but Sam admits that he thinks something is just wrong with him and that he'll never be normal. Dean can't stand Sam thinking about himself that way, so he decides to tell him the truth. But Ezekiel takes over before he can say anything and warns Dean to not even try.

In Holy Terror, Sam and Dean go on a case to investigate multiple angel slaughters. They meet Castiel, who is attempting to help his angel brethren, even as a human. After this encounter, Ezekiel takes over and reminds Dean that he can't be near Castiel, so Dean sends Castiel away again. Ezekiel walks outside and runs into Metatron, who reveals that he knows that "Ezekiel" is actually Gadreel, the angel who let Lucifer into the Garden of Eden, and was locked up for thousands of years. Metatron offers him a role in the rebuilding of Heaven and Gadreel is so desperate to clear his name that he accepts, so Metatron gives him a piece of paper with an assassination target for him to take care of. Meanwhile, Dean starts to worry that "Ezekiel" hasn't been telling him the truth. He and Kevin plan a spell that can knock the angel out of control so he can talk to Sam, but Gadreel overhears the conversation and changes the symbol, tricking Dean into believing he's Sam and knocking him out. Gadreel kills Kevin (the assassination target) and steals Sam's body, leaving Dean crying over Kevin's corpse.

In Road Trip, it's revealed that Gadreel has trapped Sam in a fantasy world inside his own head, where he believes he is working on cases with Dean. Dean, Castiel and Crowley capture Gadreel and attempt to separate his mind from Sam's so that Sam can expel the rogue angel, but fail, so Crowley possesses Sam and explains the situation. Sam fights Gadreel and manages to overpower him, expelling the angel from his body. Castiel heals some of the effects from the trials that Gadreel wasn't able to and promises to stay and keep healing Sam until he's better. Sam is furious at Dean's deception over the last few months, and when Dean decides to leave, Sam lets him.

While Dean is off on his own in First Born, Castiel discovers that Sam still has some of Gadreel's grace within him, and they try to use it to locate the angel. And even though Sam is willing to sacrifice himself for it to work, Castiel is not and he completely heals Sam, telling him that he wouldn't want to lose him and eliminating the last of the grace.

In Sharp Teeth, Sam and Dean reunite on a case while looking for Garth. And although the brothers work the job together, Sam tells Dean that he's still angry and that they obviously aren't on the same page anymore. He says that they can't be brothers anymore, only hunting partners. And in The Purge, after Dean refuses to apologize, Sam tells him that he wouldn't have done the same thing if their situations were reversed.

In Blade Runners, Sam, Dean and Crowley team up to locate The First Blade, the only weapon that can kill Abaddon. Working together, they locate former Man of Letters Cuthbert Sinclair who has the Blade. Revealing themselves to be Henry Winchester's grandsons, Sam and Dean are able to get into Cuthbert, aka Magnus's lair. However, when Magnus learns that Dean possesses the Mark of Cain, he teleports Sam outside as he plans to add Dean to his collection. With Crowley's help, Sam gets back inside, but is captured by Magnus who plans to torture Sam to make Dean willing to do what he wants. Crowley frees Dean who decapitates Magnus with the First Blade and Sam has to talk him out of the uncontrollable rage he experiences as a result. In the aftermath, Sam suggests killing Crowley now that they have what they want, but Crowley steals the Blade from them, only intending to give it back once they've found Abaddon.

In Mother's Little Helper, Sam is forced to take a case by himself because Dean insists that he's too focused on finding Abaddon. Sam travels to Milton, Illinois where normally good people suddenly become violent murderers. Sam stops one of the murders and finds out that the affected people are similar to what happened to him when he was soulless. Hearing Julia Wilkinson, an ex-nun, mention demons, Sam asks her what happened and learns that Henry and Josie Sands (Abaddon's vessel) traveled to the town in 1958 to investigate similar happenings. Julia reveals that Henry and Josie exorcised two of the demons creating soulless soldiers for a demon army. But one was Abaddon who possessed Josie and had the other demon continue her work in secret. Sam travels to the convent and finds the demon and the victims' souls captured in jars. Sam uses a recorded exorcism to distract the demon, then kills her and releases the souls back to their owners. After thanking Julia for her help, Sam returns to the bunker and tells Dean what he learned.

Sam and Dean finally manage to capture Gadreel in Meta Fiction, but Sam chooses to return him to Metatron to trade for Castiel's life. They plan on trapping Metatron at the exchange, but Metatron reveals that he's been using the angel tablet to charge himself up, and now he has powers equal to God.

The Winchesters help Castiel with an interrogation in King of the Damned  and learn that Metatron has a secret door to Heaven. Crowley calls them with Abaddon's whereabouts, so they travel to his location in order to kill her. Dean tells Sam that Crowley warned him about some demons in the basement of the hotel, so Sam goes down to check. But when the room is empty, Sam realizes that Dean lied to him in order to get him out of the way. He arrives just in time to see Dean kill Abaddon with the First Blade, but he won't stop brutalizing the corpse and Sam struggles to get Dean to finally drop the blade. They spare Crowley's life and tell him to return his son (that Abaddon plucked out of the time stream as a bargaining chip) to his proper time, but Crowley refuses and disappears. On the drive home, Sam tells Dean that he's concerned about his worrisome attachment to the blade and asks that they get rid of it now that they don't need it anymore. Dean refuses.

In Stairway to Heaven, Sam continues to worry about Dean's growing dependence on the First Blade. He asks Dean to leave it at the bunker while they go to help Castiel, and his brother agrees. They find that some of Castiel's angel followers are attacking others in suicide bombings. Dean stays behind to interrogate the group while Sam and Castiel search for Metatron's doorway to Heaven. They find a warehouse full of traps, but once they get past them, the whole thing turns out to be a fake. Sam and Castiel return to find that Dean lied about keeping the blade, and that he's killed Tessa the reaper with it. Castiel's army ask him to kill Dean for his crimes, but Castiel refuses and the rest of his angels leave. Sam tries to bring up the blade again, but Dean tells him that he's the only one who can kill Metatron and that Sam doesn't have a say in anything they do until that's done. Gadreel shows up at the bunker, telling the three of them that he's defecting from Metatron's side after finding out that he secretly orchestrated all of the angel bombings. He asks for their forgiveness, but Dean attacks him with the First Blade.

In the season finale, Do You Believe in Miracles?, Sam and Castiel try to restrain Dean from killing Gadreel and manage to lock him up in the bunker's dungeon. They find Gadreel and (after some reluctance on Sam's part) all decide that Dean is their best bet at defeating Metatron. They return to the bunker to find that Dean has escaped, and while Castiel and Gadreel try to sneak into Heaven, Sam goes after his brother. He finds Dean working with Crowley and tells him that they have to do this together, Dean agrees and they go after Metatron. Dean starts to apologize about letting Gadreel possess Sam and Sam forgives him, then Dean knocks Sam out, telling him that it isn't his fight. Sam wakes up and goes after Dean, but arrives too late to stop Metatron from stabbing him through the heart. Metatron teleports back to Heaven and Sam tells Dean that he lied about not wanting to save him. Dean dies in his arms and he cries over his brother's body. He takes Dean's corpse back to the bunker and tries to summon Crowley for a demon deal in order to save Dean. Not knowing that Crowley shows up on his own to place the First Blade in Dean's hands, which revives him as a demon...

Physical Appearance
He has shaggy brown hair that grows longer and smoother in later seasons; he had a fringe as a child as well as in the first two seasons, but now parts it to show his forehead. He has dark green eyes. He is noted by other characters to be handsome. Sam is very tall, 6'4" having a muscular build with broad shoulders and chest. This is especially ironic considering that he used to be teased for being short and wiry as a teenager. Like Dean, Sam often wears multiple layers of clothing (such as jackets, hoodies, and plaid shirts) as well as jeans and boots. Recently in Season 8 of the series, Sam who is known for always having a clean shaved face, has been sporting some facial stubble similar to Dean.

Personality


Sam is usually kind, empathetic, intelligent and independent; he can also be arrogant and stubborn. He is often the exasperated voice of reason in his relationship with Dean, who in turn sees him as exaggeratedly prissy and teasingly calls him "bitch". Dean actually has respect for Sam as a hunter and trusts Sam to "have his six". Sam shows some obsessive-compulsive tendencies, such as the desire to be in control of his situation and being fastidious about cleanliness and order. He does not seem to drink alcohol as much as Dean does and has a much healthier diet than his brother (Dean himself scoffs at Sam's diet and calls it "rabbit food"). Sam also has a crippling phobia of clowns, due to his brother often leaving him at Plucky Pennywhistle's Magical Menagerie when they were children.

Because of his intelligence, Sam is usually assigned the role of researching information for hunts. He normally remembers details that Dean overlooks and is prone to make connections quicker than his brother. He also knows a great deal of information that causes Dean to label him a "walking encyclopedia of weirdness". In college, Sam scored a 174 out of 180 on his LSAT, which Jessica noted was "scary good" in the series pilot. In spite of their bickering, Sam has looked up to Dean since they were children and knows him better than anyone else. He tries to get Dean to open up about his emotions and problems, and encourages him to take care of himself; on several occasions, he has even been frustrated by his brother's fixation on placing Sam's well-being above his own. However, Sam shows similar protective tendencies towards Dean, particularly after Dean makes his deal and returns from Hell as a shadow of who he used to be, to the point that Sam's memories of Dean allowed him to regain control of his body while possessed by Lucifer. Sam tends to be driven by feelings of anger and vengeance.

As a teenager and even as a young man, he argued with his father constantly whenever they were together. Sam wanted to live a normal, "apple pie" life instead of continuing to hunt, which led to most of his arguments with John and his estrangement from his family at the beginning of the series. After Jessica's death, Sam became fixated on vengeance, but still held out hope for eventually returning to Stanford. Early in Season 1, Sam was more focused on finding Jessica's killer than he was on following John's instructions on which hunts to take, something that often put him at odds with Dean. He was obsessed with revenge, and was even willing to sacrifice his life to kill Azazel, although he ultimately proved that he valued Dean's life over the demon's death in "Devil's Trap".

After John's death in In My Time of Dying, Sam focused all of his attention on hunting instead of returning to a normal life. He felt guilt for angrily confronting his father in his final moments and for not realizing that he had been planning on sacrificing himself. Sam put all of his energy into doing what he thought John would want him to and kept trying to get Dean to deal with their father's death in a healthy way. After the reveal of John's ultimatum to Dean and the discovery of the other "special children", Sam became terrified that he would somehow turn evil. He made Dean promise to kill him if anything were to happen. Everything came to a head in All Hell Breaks Loose: Part One, when Azazel placed all of the special children in a death match. Sam was killed because he refused to murder another human being, but when Dean brought him back to life, Sam killed his murderer without hesitation. And after finding out Dean had made a demon deal, Sam declared that he would save his brother no matter what.

In Season 3, Sam spent most of his time trying to save Dean from his deal. He became frantically obsessed with doing everything he could to stop Dean from going to Hell - even going so far as to try to convince Dean to turn them both into monsters and harvest organs for their survival in Time Is On My Side. Sam kept struggling to come up with some way to save his brother to the very end, but ultimately wasn't able to. And he was forced to watch helplessly as hellhounds tore Dean apart.

Following Dean's death and condemnation to Hell, Sam became so fixated on avenging his brother and killing Lilith that he almost turned himself into a monster. Due to his grief at Dean's death, the demon Ruby was able to manipulate Sam into a sexual relationship and convinced him to start drinking demon blood, claiming it was the only way he would be able to avenge his brother. Even after Dean returned, Sam was unwilling to let the desire for vengeance go and he continued the affair in secret. Sam was repeatedly warned by Dean and Castiel that he was making mistakes, but he disregarded their advice, believing that he was the only one who could stop Lilith from releasing Lucifer. After Zachariah manipulated a fake voicemail message from Dean, saying that he didn't love Sam anymore and was planning on killing him, Sam decided to take Lilith down on his own in a possible suicide mission. Sam was able to defeat Lilith with his powers, but didn't realize that Ruby had lied to him and that Lilith was actually the final seal to unlock Lucifer's Cage. And as a result of his arrogance, Sam ended up being the one to release Lucifer from Hell and begin the apocalypse.

Sam felt extremely guilty over his role in freeing Lucifer throughout the majority of Season 5, and spent a large portion of his time trying to make amends. He also took responsibility in his part of starting the apocalypse. In Sam, Interrupted, Sam confessed that he always felt angry and he didn't know why. And that he tended to blame other people for his anger, instead of accepting it as a personal flaw. In Swap Meat, when he temporarily switched bodies with a teenaged boy and was forced to lead said teenager's life, he told Dean that the boy's ordinary life "sucked", and seemed to decide to forgo normal life in favor of being a hunter. In Swan Song, Sam's desire to set things right finally culminated in him sacrificing himself to save the rest of the world, throwing himself into the Cage with Lucifer and Michael in order to protect his brother.

During the time that Sam was soulless in Season 6, he lacked empathy and behaved like a sociopath. Without any emotions or sense of morality, he was often willing to overlook the deaths of civilians as collateral damage, which was an extreme departure from Sam's normal desire to help people and protect the innocent. Without his soul, Sam also felt nothing for any of his loved ones, telling Dean point blank that he didn't care about him, and he even tried to murder Bobby in an attempt to prevent his soul from being returned to his body. After his soul was replaced, Sam again felt great remorse for his actions and spent the rest of the season struggling to make up for what his soulless self had done.

In Season 7, after Castiel brought down the wall in Sam's head, Sam began to lose his sanity as a result of the damage done to his soul in Hell. He started to see hallucinations of Lucifer tormenting him, and had a hard time determining what was real and what was a flashback of his torture in the Cage. Dean managed to help Sam distinguish between the two, and Sam was able to block out the worst of the hallucinations. However, in Repo Man, Dean was captured by a serial killer and Sam became desperate enough to save his brother's life that he turned to Lucifer for help. He was able to save Dean, but the reliance on his hallucination meant that he could no longer turn them off, and his visions became so severe that Sam almost died due to fatal insomnia. Dean became determined to save his brother's life in The Born-Again Identity and, luckily, came across Castiel. Sam's mental stability returned when Castiel absorbed Sam's insanity into himself to atone for his actions.

After Dean and Castiel's disappearance in Survival of the Fittest, Sam spent a year thinking that his brother was dead. He "spiraled" out of control for a while, but eventually found some semblance of normality with Amelia. It was at this point that Sam started to re-imagine the possibilities of a normal life. After Dean's reappearance, Sam immediately returned to his side, but Dean was hurt when he found out that Sam hadn't looked for him while he was in Purgatory. Sam defended his choices and grew jealous of Dean's close relationship with Benny, which led to a growing strain between the brothers. After bumping into Amelia once more, Sam realized that he wanted to stay by Dean's side and chose his brother over his ex-girlfriend. Sam became determined not to let Dean down again and took on the weight of the trials to prove himself. They took an extreme toll on his health, and as Sam got sicker, he became ever more defensive of Dean's attempts to mother him. He eventually got to the point where he was so ashamed of letting his brother down that he was willing to commit suicide in order to finish the trials. Dean managed to talk him back from the edge, but they weren't able to cure Sam before he succumbed to the effects.

Sam started Season 9 in a coma, dying from what the trials had done to his body. He remained somewhat suicidal, deciding to go with Death if he could promise that no one would be able to get hurt by bringing him back. But Dean managed to trick Sam into allowing the angel Gadreel  to possess him, and for the first half of the season, Sam seemed to be in a much healthier place emotionally. However, once Sam found out that Dean had lied to him, he became furious. He told Dean they couldn't be brothers anymore and their relationship remained tense until the end of the season. Eventually, Sam's worries over Dean's reliance on the First Blade took precedence over Sam's anger, and when Dean attempted an apology, Sam forgave him. But they made up just in time for Sam to see his brother die in his arms, and Sam's grief at Dean's death propelled him to try and make another demon deal. Going back on everything he said that he wouldn't do in order to save Dean.

Equipment
In Season 1, Sam owns a laptop, which he uses to gather information for hunts. In Season 2, he finds it in the wrecked Impala, busted. Sam soon replaces it but in Season 7 this other laptop is smashed by Frank Deveraux on the basis that it is not safe and the Leviathans may be tracking it, forcing Sam to once more replace it. For the first three episodes of Season 6 Sam owns a black Dodge Charger with the license plates I4Z 0892 which Sam has customized for hunting. It is destroyed in Castiel's fight with another angel in "The Third Man", something that Dean was pleased to see. In terms of laptops in Season 1, he owns what appears to be a Dell Inspiron 6000 laptop, which he uses to gather information for hunts. The first time Sam uses the laptop is in the second episode "Wendigo", where he plays a video message. In terms of cellphones in Season 1, Sam uses a Palm Treo cellphone. By season 2, Sam appears to own a Verizon-branded Motorola Q which has on at least one occasion (in "Hollywood Babylon") been used to visually track unseen ghosts. This phone however was destroyed in the third season episode "Fresh Blood." In the fourth season, namely "Sex and Violence", Sam is seen using the BlackBerry 8800. Sam has since changed models and is currently using the Blackberry Bold 9000, as first seen in the season 4 finale, "Lucifer Rising".

Weaponry
It is a common misconception that Sam uses a chromed Beretta 92FS loaded with silver rounds. However, it has been officially stated by Christopher Cooper that it is a Taurus Model 99 (though it appears in most shots to be a Model 92, which is a bit thicker around the trigger guard than the Beretta). It is a standard 9mm with a 10-round magazine. When he was soulless, Sam utilized a Heckler & Koch Mark 23 Model 0. The boys do own a blue steel Beretta 92, but it is predominantly used by Dean in the series. Sam also uses a pistol grip 4-shelled 12 gauge shotgun loaded with rock salt. Sam often uses close range weapons while Dean seems to prefer the longer range weapons. Sam also uses Ruby's demon-killing knife, after taking it from her. During the latter seasons, both him and Dean start to employ angel blades, taken from dead angels when they turn against the Host of Heaven.

Powers and Abilities
Due to his training as a hunter by his father, Sam is skilled with firearms and melee weapons. Like Dean, he is skilled in criminal acts, such as lock picking, computer hacking, and car jacking. In the first two seasons he is often hesitant about using these skills because of his desire to be a 'normal' citizen, however this lessens over time. On two separate occasions, Dean has warned the powerful vampire Benny not to underestimate Sam, as he could and would kill him given the chance. He is proficient in hand-to-hand combat and possess remarkable physical strength for a human, being to hold his own and even overpower certain supernatural creatures such as certain types of monsters and lower-level demons. The most recent example being him overpowering a hellhound and killing it single-handedly. He is also well-versed in weapons use, from blades to firearms and kill any creature that is affected by this type of weapons.

He has vast knowledge of the supernatural and is considered an "encyclopedia of weirdness" by Dean. He is proficient in reading and remembering spells written in foreign languages such as Latin and is often stuck with doing the research for their latest hunt. Having learned how to make hex bags from Ruby, Sam also possesses the ability to hide from demons. Sam is also a quick thinker and improviser as he managed to prevent a demon from escaping his vessel by reciting an exorcism chant backwards. He is also shown to have an adequate knowledge of Spanish. Sam is perceptive to other's body language and can easily pick up on unconscious gestures to read their "poker face". He is an expert tactician, able to fight or diplomatically steer his way out of many complicated situations. He also has a great sense of direction and time, at one point being able to find a vampire's nest while blindfolded by keeping track of the time, the number of turns the car took and the sounds he heard during the journey.

Sam has an in-depth knowledge on the workings of various law organizations (FBI, CDC, Police, etc) enough to pose as one if the situation requires it. Sam is also the technology expert of the duo, as he's the one doing research and technology-based jobs.

Sam has also demonstrated that he possesses great willpower. Upon seeing something from his past in the Impala, he was able to use his memories to briefly overpower Lucifer's possession of him and regain control of his body. He later replicated this feat with the less powerful Gadreel, though in that scenario he seemed to use his anger as well as his will.

One of his greatest traits is his physical and mental endurance. After his revival and having his soul restored, Sam managed to cope with the mental hallucinations caused by being tortured by Lucifer for several months, while remaining a functional hunter, before ultimately starting to cave in. The next year, when undertaking the trials to close the gates of Hell, despite the extreme physical damage and resulting weakness it caused him, Sam still managed to perform some respectable feats, such as knocking Dean unconscious with two punches.

As the vessel of Gadreel, Sam possessed the ability to expel him, but was kept from being aware of his possession to prevent exactly that. Once Crowley made him aware of the truth, Sam overpowered the angel and expelled him.

Special Child Abilities
As a result of being fed demon blood as a baby by Azazel and thus being branded as one of the Special Children, Sam has exhibited over the course of the series various supernatural powers and an immunity to demon powers and diseases. Initially his powers were weak and fluctuating due his hesitation of using said powers. At the start of the fourth season, Sam has begun drinking demon blood under Ruby's tutelage in order to become stronger, eventually manifesting the ability to exorcise demons with his mind. By consuming ever greater amounts of demon blood (which became an addiction to him), his powers continued to grow to the point where he could exorcise and destroy white-eyed demons such as Alastair and ultimately Lilith. After Lucifer's release, it was finally revealed that the reason Sam was fed and compelled to feed on demon blood, was to strengthen and prepare him as the perfect vessel for the Archangel on Earth. When having consumed several gallons of demon blood, Sam destroyed Lucifer's demon bodyguards with a minor thought. Sam would lose his powers and craving for the blood on two occasions: first when Lucifer was released and God took him and Dean away from Lucifer and cleared Sam from the blood, the second, when he was resurrected and released from Lucifer's Cage. Sam's powers included:


 * Precognition - Sam possessed the power to see into the future and even have visions of people in danger.
 * Clairsentience - Initially, Sam's powers manifested solely as a form of heightened senses and occasionally as confusing premonitions of the future.
 * Telekinesis - When under extreme situations, Sam displayed minor feats of telekinesis. His power grew considerably the more demon blood he consumed to the point where he could throw around and restrain top-level demons such as Alastair and Lilith by using his mind.
 * Super Strength - The demon blood also increased Sam's physical strength, allowing him to overpower low-level demons and humans, including his brother Dean.
 * Immunity - Sam was completely immune to a variety of demonic powers and of those of other Special Children. Even before he started to consume demon blood, he was unaffected by Andrew Gallagher and Ansem Weems' Mind Control powers, the Croatoan Virus, and Lilith and Samhain's White Light. Although Lilith was initially able to use telekinesis to incapacitate Sam, he became immune to her powers (including her telekinesis) after she tried to kill him with White Light. As he continued to drink demon blood, he even became immune to other demons' powers, such as Alastair's telekinesis. However, after he stopped drinking demon blood, he lost his immunity to other demons' powers.
 * Exorcism - Under Ruby's tutelage, Sam learned how to use his powers to exorcise demons with his mind. Initially he had extreme difficulty with controlling and maintaining this power due to his initial hesitation of drinking demon blood. Though he was able to exorcise Samhain with a minimal consumption of demon blood, he was unable to do more than make Alastair choke and later on had no effect whatsoever on Lilith. However once he committed himself to drink the blood and destroy Lilith, his powers grew to the point where he could exorcise virtually any demon. After drinking two demons dry he could exorcise five demons at once. As he continued, his powers evolved to the point of being able to permanently kill demons.
 * Demon Detection - Under severe craving for demon blood due to Famine's power, Sam could detect demons within a short proximity.
 * Demon Torture - Sam also was able to cause demons extreme levels of pain which he used to torture them for information. He was so skilled at this ability that Alastair (who had a very strong will and withstood hours of torture from Dean and the angels) broke within seconds and another demon begged for death.
 * Demon Destruction - After drinking more blood than usual from Ruby and having been honing his powers for months, Sam was able to kill a demon as powerful as Alastair. By drinking an even larger amount of blood from both Ruby and another demon, drinking that demon dry, Sam managed to kill the firstborn demon, Lilith, though it still required extreme concentration and difficulty and left him drained of his abilities. When preparing to say yes to Lucifer, Sam drank several gallons of demon blood, which allowed him to kill Lucifer's demon bodyguards with minimal mental effort and without moving.

Deaths
Throughout the course of the series, Sam has died multiple times. He has died as many times as Dean, excluding Mystery Spot. His resurrection seems to have been the catalyst for Sam's increasingly cold nature and it has been insinuated by Azazel that when he was resurrected, he did not come back "100% pure Sam".


 * The very first time Sam died was in All Hell Breaks Loose - Part 1, where he was stabbed in the back by Jake Talley. He was resurrected by the Crossroads Demon in All Hell Breaks Loose - Part 2, but Dean paid the ultimate price with his soul.


 * Sam was struck by lightning and briefly died in "Wishful Thinking" when Hope wished him dead. However, this was quickly reversed.


 * Zachariah takes Sam's lungs in "Sympathy for the Devil" long enough for Sam to die briefly. Castiel orders him to return the boys back.


 * During the episode "The Song Remains the Same", Sam was killed by Anna to prevent him saying yes to Lucifer. Michael brought him back, however.
 * Both Sam and Dean were killed in the episode, "Dark Side of the Moon" by two angry hunters for starting the apocalypse, but were resurrected by Joshua.


 * During the Season 5 finale, "Swan Song", Sam sacrificed himself by leaping into Lucifer's Cage, dragging Michael, Adam, and Lucifer down with him. He went briefly to Hell but appeared at the end of the episode, staring at Dean's new family having dinner. It's later revealed that Castiel resurrected him but without a soul. When Death finally brought back his soul, he placed a wall in Sam's mind.

Relationships

 * Sam and Dean - Sam and Dean are brothers.
 * Sam and Bobby - Bobby was like a father to the boys.
 * Sam and Castiel - Sam and Castiel are friends.
 * Sam and Ruby - Sam and Ruby were enemies who became lovers, and then enemies again.
 * Sam and Jessica - Sam's girlfriend while at university.  Her death was the reason he started hunting again (Jess was killed by Yellow-Eyes.)  Sam was planning to propose to her.
 * Minor Relationships - Other relationships Sam has had.

 * Sam's birthday is May 2, which means his zodiac sign is Taurus.
 * Sam's aliases include Agent Hamill, Robert Singer, Mr. Berkowitz, Detective McCreedy, Father Frehley, Dr. Jerry Kaplan, Deputy Marshal Frank Beard, Detective Dante, Police Chief Phil Jones, Agent Page, Detective Bachman.

 * According to Eric Kripke, Sam was originally the main protagonist of the series and the story centered around him.
 * Sam suffers from Coulrophobia (fear of clowns).
 * A running gag in the show is that Sam almost always gets hit across the back of the head.
 * Sam was apparently named after his and Dean's maternal grandfather, Samuel Campbell, just as Dean was named after their maternal grandmother, Deanna Campbell.
 * He only allows those closest to him, such as Dean and John, to call him "Sammy", as Gordon Walker learned the hard way in "Bloodlust". However Crowley, Ruby and Meg also called him Sammy a few times.
 * Sam displayed more powers in Supernatural The Animation. In "Rising Son", it's shown that he made a stag-like monster implode when he was 7 years old. In Part 1 of "All Hell Breaks Loose" he knocks an onrushing Jake back with some kind of energy and in Part 2 uses it to sever Jake's arm. He then beats Jake to death, possibly with super strength.
 * Sam is one of two characters shown to have been possessed by both an angel and a demon (the other being his father). However, unlike John, Sam has been possessed by an angel and a demon at the same time.
 * In "The Song Remains the Same", Michael reveals that Sam is descended from the biblical Cain, the first murderer, who killed his younger brother, Abel. The "curse" Sam often describes as hanging over his life may be the remnants of the legendary curse God laid on Cain as a punishment for his crime, the "Mark of Cain."

 * Many of the characters Sam is romantically or sexually connected to end up either dying, being revealed as a supernatural being, or both; exceptions include (to the best of our knowledge) Lori Sorensen ("Hook Man"), Dr. Cara Roberts ("Sex and Violence"), Lindsay ("Free to Be You and Me"), and Amelia Richardson (Season 8). Dean referenced this trend in-show in the episodes "Sex and Violence" and "Season 7, Time For A Wedding". Sam himself brings it up in "Rock and a Hard Place," saying that most of his relationships don't end well while at a chastity group with Dean whole-heartedly agreeing.
 * Sam is the only Winchester to not have successfully made a deal with a demon, as both Mary & John made deals with Azazel whereas Dean made a deal with a female Crossroads Demon.
 * Sam, like several other members of 'Team Free Will', has been to Hell, Purgatory, and Heaven.

 * Sam is the only being on the show to be possessed by four different beings: the demon Meg, Lucifer, Gadreel and Crowley. The latter two simultaneously for a brief time.
 * Sam is currently the only known human on the show to be possessed by both an angel and a demon at the same time.
 * Despite being briefly possessed by him, Crowley never actually did anything to control Sam's body, a first for someone being possessed.
 * Interestingly, Sam with no soul was similar to the concept of a philosophical zombie, a creature in a thought experiment that has no soul/mind/internal experience but acts exactly as if it does, eg. exactly like a person.
 * When Sam had no soul, he used a different gun than the souled Sam uses. This was seen prominently when Soulless Sam and Souled Sam confronted each other: each used the gun they preferred to use while in control of Sam's body.
