Sam Winchester

Samuel "Sam" Winchester is a hunter who hunts supernatural creatures with his older brother Dean Winchester. He is called "Sammy" by those closest to him.

Sam is the son of Mary and John Winchester, has a half-brother named Adam Milligan, and was the true vessel for Lucifer.

He and Dean come from a family of hunters on their mother's side, but this fact was unknown to them for some time. Sam was named after his maternal grandfather, Samuel Campbell. His grandmother is Deanna Campbell.

Apperance
Sam is shown to have an impressive physique. He is shown to be taller than his older brother. Originally as a teenager, he was wiry and he was teased about it, but due to exercise and eating healthier (while Dean is known to eat very unhealthy foods), he grows stronger and his appearance is more fit.

Personality
Sam is different from his older brother in that he is sensitive, rational, more innocent, and used to be more concerned with living a "normal 'apple pie' life" than his brother. In spite of this, it is obvious that he would do anything for Dean. He rebelled against his father's attempts to raise him as a demon hunter and enrolled in Stanford University after having a harsh fight with his father. Sam looks up to Dean in many ways and sometimes adopts some of Dean's mannerisms. Over the years, Sam has given up on the idea of a normal life, and has accepted that he is different.

Sam is the stereotypical "smart one" of the group, often stuck with the bulk of the research involved in cases. He normally remembers details that Dean overlooks and is prone to make connections quicker than his brother.

During the time when Sam was soulless in Season 6, he thought more logically instead of emotionally. Sam didn't care about people or his brother like he did when he had a soul, and was practically a machine. Sam has a ruthless side that only appears in times of great stress, like when Dean was in danger of going to Hell as part of a deal. This ruthlessness was very apparent when Sam was without his soul, but this may have only been due to him lacking the morality of his soul.

Sam has a crippling fear of clowns, first seen in the episode "Everybody Loves a Clown." It is revealed in "Plucky Pennywhistle's Magic Menagerie" that Sam's fear came about during his youth when Dean would leave him at Plucky's to "go pick up chicks." Sam's time there seems to have been the start of this fear.

As the hallucinations of Lucifer are getting worse, Sam's seemingly becoming more amenable to the Devil's suggestions, as demonstrated in Repo Man.

With Castiel's miraculous return, and due to his intervention, Cas was able to shift Sam's 'wall' problems unto himself.

Weapons
Sam uses a chromed Beretta 92fs loaded with silver rounds and uses a pistol grip 4-shelled 12 gauge shotgun loaded with rock salt. Is also very talented at hand to hand combat as shown in Season 1's Pilot, when he fights Dean in his dorm room. Sam often uses close range weapons while Dean seems to prefer the longer range weapons.

Even though Sam is usually more concerned about not hurting the hosts and others possesed by demons, he has actually used The Colt on more occasions than any other known person, including Samuel Colt. Sam has Ruby's Knife, which he takes from the demon Ruby.

Equipment
In Season 1, he owns a laptop, which he uses to gather information for hunts. In Season 2, Sam finds it in the wrecked Impala, busted. Sam soon replaces it, since he always carries a laptop around. In Season 7 the laptop is once again destroyed, this time by Frank Deveraux, who smashes Sam's laptop only to replace it with another, citing it's not safe and the Leviathans may be tracking it.

Powers and Skills
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.

He has vast knowledge of the supernatural and is considered an "encyclopedia of weirdness" by Dean. He is proficient in reading spells written in foreign languages such as Latin and is often stuck with doing the research for their latest hunt. 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.

Having learned how to make hex bags from Ruby, Sam also possesses the ability to hide from demons. He exhibits both telekinetic and precognitive abilities at various times throughout the series. Many of Sam's powers are a result of being fed demon blood by Azazel; He is immune to a demon-spawned virus, called Croatoan, presumably because of his demon blood intake. Sam's visions do stop after the death of Azazel in Season 2; however, according to Ruby, his powers are simply dormant. Ruby states that if he was in full control of his power, he could blow away demons as powerful as Lilith with no effort. As the series progresses, Sam learns to hone and develop these powers. In "No Rest For the Wicked", Sam demonstrates an immunity to Lilith's attack, and later on Samhain's similar-looking attack.

At the start of the fourth season, Sam has learned to use his powers to exorcise demons with the help of Ruby, who is occupying a new host. In "Death Takes a Holiday", Sam is shown to have grown more powerful, resisting Alastair's attempt to telekinetically throw him when Sam had previously been unable to do. He then uses his telekinetic power to pin Alastair to a tree and attempts to exorcise him, another feat he had been unable to accomplish before. In "On the Head of a Pin", it is revealed that these "boosts" in his abilities are then a result from drinking Ruby's demon blood. Sam's powers are increased to the point where he can kill demons outright, as opposed to simply exorcising them. The same light flickers under their skin as if killed with the Colt or the knife. He is also able to telekinetically grip demons with his powers and torture them. These powers have not been seen since Sam has returned from Hell. It is possible that Sam may still have these abilities, he may just need to drink more demon blood to access them.

These Powers Included:
 * Clairvoyance (manifesting as visions/premonitions)
 * Telekinesis (after drinking Demon Blood, previously through heightened emotion and adrenaline)
 * Clairsentience (manifesting as a "supernatural sense")
 * Demon Exorcism (after drinking Demon Blood)
 * Demon Destruction (after drinking large quantities of Demon Blood)
 * Croatoan Virus Immunity
 * Demonic White Light Immunity

Early Life
Sam 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 demon Azazel, whom his mother walked in on while he was standing by Sam's crib, feeding him demon blood.

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 every few weeks while their father hunted supernatural beings and their mother's killer. Until he turned 8 years old, Sam believed his mother had died in a car accident and his father was a traveling salesman until Dean revealed to him the existence of the paranormal.

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."

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. Time passed and after a heated argument with his father, Sam eventually went to Stanford University thus leaving his family and their hunting crusade behind him.

Season 1
At the start of the series, Sam is seen a senior at Stanford 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.

In much of Season 1, the Winchester brothers hunt down mystical creatures and urban legends like the wendigo, folklore's Bloody Mary, and shape-shifters. 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 where several of their hunts take place.

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 dissappointment.

"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 follow through and Azazel escapes 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 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, it becomes clearer that he shows greater concern for Dean than the whereabouts of his father.

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 Dean'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" (2.2) 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, her daughter, Jo, and a computer genius by the name of Ash 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 but also stands up to his brother.

"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 duo of vampires. When Gordon finds the vampires, he is ready to kill when Sam insists they are harmless to humans.

The only brother with a college background and an ever growing ability to foresee events, 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.

Since "Hunted", Sam has learned what his father told Dean moments before his death: that if he (Dean) could not save Sam, he would have to kill him. 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 the episode "Born Under a Bad Sign", Sam is possessed by the same demon responsible for Meg's possession in Season 1 (see Meg Masters). It is also hinted at that this is also the same demon that lead to the death 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, but their father is dead.

In the season finale, 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. Although Sam tries to protect the other children, various fights ensue, and the children are killed off one by one. Eventually, only Jake and Sam are left, at which point Sam is stabbed by Jake Talley and dies in Dean's arms.

A desperate and depressed Dean sells his soul to the Crossroads Demon for Sam's resurrection. 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 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 lost 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 wanting to never give up hope, he lodges in Illinois, close to where his brother is buried. After Bobby learned of Dean's escape, the two go to visit Sam. They find him enjoying his "wild side." A confused Sam tries to attack Dean, but Bobby stops him and tells him that it's the real 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 helps Dean defeat the spirits of Agent Henricksen 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 made love at least once, and Ruby began helping Sam develop his powers.

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.

As the series progresses, he begins to become more cold and cruel than he ever was. It is revealed in "The Rapture" that he is addicted to the demon blood. During "Lucifer Rising" it was revealed that Sam had been used by Ruby the entire time. In a plot to kill Lilith, thus breaking the final seal releasing Lucifer. Sam succeeded in destroying Lililth, but as a result, Lucifer was released from his prison.

Season 5
In the direct aftermath of Sam breaking the final seal and 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 and find it hard to reconnect.

That fact alone was emphasised 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, who 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, 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 the enormous task of 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 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 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 enough for him to 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 gives up on finding out and 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 dead for years by Azazel. Soon, Sam goes hunting for dijinns and discovers that they're going after Dean next and nearly kill him.

This allows him to reunite him with his brother who is forced to tell him that he has been back the entire time and that he chose not to tell him because he 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 introduced Dean to their third cousins and Grandfather, from their mom's side.

Then Sam and Dean take Lisa and Ben to safety at Bobby's until they take care of the dijinns. The dijinns attacked the brothers and is nearly killed but is saved by Samuel and the others. Later, Dean decides not to return with Sam and to stay with Lisa and Ben, and offers 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, 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 admits he needs help. Dean responds with beating Sam unconscious, and calling on Castiel for assistance.

Upon inpection, Castiel determines Sam is physically healthy, but his soul is missing. Dean plans on keeping Sam tied up, but Sam sets himself free and tells 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. Sam and Dean join in on the hunt, with Sam following Samuel's group and Dean standing guard with Gwen. When Dean sees Sam walking the vampire into a van, Dean confronts Sam, and Sam states that it was his idea because they needed to ask questions, where Dean is a 'shoot first, ask questions later' kind of hunter.

Sam helps Dean find out where Samuel is taking the creatures for interrogation by activating a GPS tracker in one of the his cell phones. They find the Alpha vampire, and take the opportunity to question him when Samuel leaves the room. The Alpha expresses an interest in Sam because of his soullessness, and later attacks Sam and attempts to turn him. Christian, revealed as a demon, prevents this and teleports the Alpha away.

Crowley then appears on the scene, and through Samuel, is revealed to be the one who raised Sam from Lucifer's cage, and is in possession of his soul. He tells them that if Sam ever wants the return of his soul, he and Dean need to help Samuel to capture creatures for him. Currently, Sam does not see any other option than to 'play ball' with Crowley until the brothers find another way to get his soul back, and then they will get him back.

Sam's behavior, however, shows that he is definitely in conflict on whether he should get his soul back or not, or even want to get his soul back. He tries to convince Dean that he is still the same Sam. He works Crowley's cases without question, and also claims that his brain works better than ever. His actions contradict this, as when dealing with a skinwalker case, Sam jumps to the conlusion that a women is the skinwalker they're looking for, and is ready to bag her up as soon as possible. When the brothers face the pack of skinwalkers, Sam orders Dean to take a shot at the pack leader, even when there was an innocent in the way.

Sam later comes clean to Dean about himself. He admits he is not his brother, that he's not the old Sam. He states he could not care less about Lisa and Ben, and does not 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 in the line of duty. He says that despite how maybe he should feel guilty, he doesn't. He only looks at the positives of being soulless, which is getting the job done and not having any emotional effect, which to Sam, is "not the worst thing", Although, after some thought, Sam decides he should probably go back to being the old Sam, and get his soul back. Dean acknowledges this.

However, Sam already shows signs of having second thoughts, or not wanting to change. When investigating the case of UFO abductions, Sam checks only one lead when Dean's abducted, but is side-tracked and picked up by a hippie chick and has sex with her, much to Dean's dismay. When the abductions are revealed to be the cause of fairies, Sam takes matters into his own hands when Dean is sent to jail. He confronts the leprechaun Wayne, who strikes a deal to lift Sam's soul from the cage. Sam expresses interest, 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, to which Sam denies with a simple "No."

Sam, while still unsure whether he wants his soul back, goes along with working for Crowley, despite Dean's remarks of them not getting anywhere. Later, Sam walks away on a small argument with Dean only to be knocked out by demons, led by none other than Meg. Sam detects her fear and suggests that she's running from Crowley, which to him makes sense, as Crowley is now the "big man on campus", and dubs Meg as a "Lucifer loyalist". When Meg asks how he knows, he simply replies it's what he'd do. He then makes a deal with her: the brothers give her Crowley ("with a bow"), but only on one condition: she must torture Crowley to get him to give Sam back his soul.

When Dean expresses unease with working with a demon again, Sam retorts that they are working with demons now and that this is their shot to stop. He also assures Dean that they will kill Meg the second they are done with them, and that they would not kill them first. He calls on Castiel to make sure of this. Sam tricks Castiel into thinking that they have found the Ark of the Covenant, to which the angel responds. When Castiel tells Sam that he is too busy with the war over Heaven to help, Sam reminds Castiel that he owes him and tells him that if he does not help, he will hunt Castiel down and kill him. Castiel joins the group for searching for Crowley.

When Samuel gives the party the location, Sam, Dean, and Castiel meet up with Meg and her demons. Sam asks for the knife, to which Meg reluctantly hands to him. Sam uses the knife to kill one of the demons, saying he did the group a favor. A few moments later, Sam overhears Dean and Castiel talking about what damage could be done to Sam with the return of his soul.

Once inside Crowley's prison, Sam and Dean get 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 bites his wrist hard enough to bleed. He uses his own blood to mark the ceiling with a devil's trap. He escapes his cell, and saves Dean from the demons.

A moment later, the brothers (along with Meg) confront Crowley. Sam demands for his soul, to which Crowley replies he simply cannot. He states that he was lucky enough to retrieve Sam's body, as Michael and Lucifer are very violent when Crowley comes in contact. He then asks Sam why he even wants it back, as he too thinks that Sam will be broken once his soul is returned (Meg agrees to this). Disgusted, Sam tells Meg to kill Crowley, in which she fails. Crowley knocks Meg over, steals the knife, disarms the devil's trap keeping him immobile, and flings Sam and Dean into the wall. Castiel intervenes, asking once again if he has the power to restore Sam's soul. Crowley says no, and Castiel burns the bones of the demon.



Outside the prison, Castiel tells Sam that they will find another way to get his soul back before leaving to take care of the monsters still in the prison. Dean tries to reassure Sam, too, but Sam tells him that he does not think he wants his soul back after all. When Dean states that Sam is not better the way he is, Sam disagrees and walks away without a word, despite his brother's calling.

Sometime later, when Dean informs Sam and Bobby that he has made a deal with Death that could result in Sam getting his soul back, and with a "wall", Sam is still unwilling to get it back, and is sure his head will explode when Dean's scheme "goes sideways". He even sneaks out the house to try and steal the Pale Horseman's ring before Dean, but is foiled as Dean catches him and holds the ring in his hand. Sam falsely states he trusts Dean with his deal, and gives him false hope not to mess it up. With Bobby given the job to watch Sam, the latter asks if he'll lock him in the panic room. Bobby asks if he has to, but Sam replies he does not, and that "Dean's gotta do what he's gotta do."

He slips Bobby's watch over him again to summon Balthazar. He asks Balthazar for a way to keep his soul out of his body, and Balthazar, who wants to screw Dean over and have Sam in his debt, gives Sam the spell "for free." He also tells Sam that he has to make his body uninhabitable for his soul by committing patricide. He "needs the blood of his father, but his father needn't be blood," so Sam resolves that Bobby is the next best thing, as John Winchester has been long dead.

Bobby realizes what Sam is up to, however, and hits him over the head. Unfortunately, Sam vanishes before Bobby can tie him up. Bobby locks the door to the basement and then locks himself in the closet, where Sam quickly finds him. Sam breaks through the door with an ax, but Bobby has set a trap door outside the closet that drops Sam into the basement. Bobby asks Sam what he's doing through the basement door, to which Sam replies he's trying to survive, as Dean does not really care about him without a soul, and rather about his brother Sam burning in Hell (speaking as if they are two different people). Sam later finds a way to escape after he gets Bobby monologuing. When Bobby leaves outside to look for him, Sam knocks him out from behind. He ties Bobby to a chair, and prepares to kill him, despite how he does not want to (he only looks at the bigger picture: he will remain soulless). However, Dean shows up in the nick of time, and knocks Sam out.

Sam wakes up chained to the bed in the panic room, and catches glimpse of Dean through the small window of the panic room's door. He remains still and silent until Death shows up by his bed with a doctor's bag, containing his soul. Death explains to Sam that he will put up a wall inside his mind that will hold back the memories of the cage. He explains it may be "a little itchy", but advises not to "scratch the wall" as he will not like what happens. Sam fights while chained, shouting for Death to stay away from him, and begging Dean for him not to let it happen. Death, however, proceeds to restore Sam's soul to his body, with the latter screaming in pain.

Sam wakes up about a week later, 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.

After a while, Sam already starts to get familiar feelings of deja vu, as of when looking through John's Journal, he asks Dean if they had hunted a Skinwalker recently. When Dean and Bobby both keep it tight-lipped, Sam goes with the next best bet: he prays to Castiel, who fills 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 to him, feels guilty and expresses a will to set things right. He is apparently not angry, but grateful towards 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 the "Great Wall of Sam" crumbling.

Sometime later, Sam tries to catch up on the year he was "gone". He then receives a mysterious text from an unknown number, giving coordinates to a small town. Sam tracks the number to Bristol, Rhode Island. He also finds out that three women disappeared there in the last week, vanishing out of thin air. Sam suggests they check out what's going on over there, and Dean reluctantly agrees.

Upon arriving in Bristol, Sam already begins to have flashbacks of his time there a year ago. He recognizes the sign of Bristol when they arrive in town, he then meets up with someone who knows him from his previous trip. When Sam starts to have suspicions of the place, Dean confirms them with a photograph he finds with Sam in the background. Dean plans on leaving the town as soon as possible, but Sam insists on staying to figure out what happened, and what is going on now. He takes responsibility for the missing people in the town, and wants to finish what he started.

Dean agrees to continue, following up with affiliates of the missing women for any clues to what might be going on. He finds out from one that she had some "loud and athletic" interactions with Sam a year ago. Meanwhile, Sam arrives at the police station only to be abruptly arrested by the same cop he knocked out a year ago.

Sam tries to convince the cop that he does not remember anything, but the cop refuses to believe him and locks him up in jail. Sometime later, another sheriff named Brenna Dobbs walks in, apparently knowing his true identity as Sam, and questions him on what happened to her husband, Roy. Sam cannot remember her at first, but has another flashback of Samuel and himself talking with the two about hunting. He tells her he does not know what happened, but he will find answers because that is his job. After some convincing, she lets him out his cell.

Dean returns home to Sam, now a fugitive, and tells him that he actually got arround being soulless, and that he knew one of the missing girls. Suddenly, on a police scanner, the two overhear of another disappearance. Dean orders Sam to stay put while he checks out the scene. As Dean walks out the door, Sam makes his way to Sheriff Brenna's house.

Sam asks Brenna for the files on the missing men from a year ago. He has a few flashbacks, including one of him and Samuel talking with Roy and Debra about family and being on the road. Samuel expresses a sentimental sense of joy and blessing when reminiscing about Mary, but Sam looks at his relationship with Samuel as nothing more than a business relationship, and that "family slows you down". Another flashback confirms that the cause of the disappearances of the men were from a creature called an Arachne. He borrows the evidence to put the pieces all together, and runs into Dean, who suggests once again to leave this for another hunter. Sam is still persistent on finishing what he's started.

As the pieces come together, Sam experiences a full flashback that fills in the blanks on what happened: the abductions the Arachne made were all of men fitting a certain profile, and used Roy as live bait to track down the Arachne. Upon finding the Arachne's lair, Sam and Samuel face off with the creature, and Sam decapitates it. Samuel suggests calling an ambulance for Roy and the others, but Sam suggests it can't be helped. He believes that all the men are poisoned, that they are dead men walking, and he suggests putting them out of their misery by killing them. He shoots all of the men, and tells Samuel to get the gasoline to burn the house down.

Upon this realization, Sam calls Brenna to check if she is okay. She asks for him to stop by, and Sam senses that she is in trouble. The brothers arrive and upon entering the shed, they find Brenna. She asks Sam if it was true that he killed Roy. Before he can answer, Dean is attacked and Sam is pinned to the wall by Roy, now an Arachne.

Roy, suddenly angry, tells Sam he got a lot of his assumptions wrong. He explained the Arachne wasn't there to feed, but rather to breed. She bit him and all the others to turn them into Arachne. By the time Sam shot him, he was already turned. He was resistant to both bullets and fire. After the fire, all the Arachne ran. Ever since then, Roy kept himself hidden for months, waiting for Sam to return to exact revenge on him. He tells Sam that all of the missing women are now Arachne as well. However, he questions whether to kill Sam or turn him. In this moment of hesitation, Dean breaks out his cobweb to attack as Brenna cuts the cobwebs off of Sam. Sam then strikes and decapitates Roy. He tries to apologize to Brenna, but she shuts the door on him.



Sam and Dean pack up to leave, with Dean wondering if Sam's okay. Sam, now feeling guilty, agrees that they should not have come back to Bristol. Dean tries to console him by telling him it was not really him, but Sam disagrees and states that in his flashbacks, he saw it clearly was him. As he wonders about what else he could've done, he collapses on the floor. Dean rushes to Sam, who receives a flashback of himself burning in Lucifer's Cage. He is out for a whole minute before waking up. Sam tells Dean it felt like a week had passed by and hit by a planet. He and Dean have a heart to heart about what has happened. So they head out on the next job where people are being killed by mannequins. They work together until Ben calls Dean home for an emergency. So Sam works this job by himself and figures out it was a woman's spirit these men bullied doing the killing. Dean later returns, but the case is completed by now.

Balthazar randomly shows up later at Bobby's house, searching for the ingredients to paint a Enochian sigil on the window. He cryptically states that Raphael is on their tail, and that he is trying to protect the brothers. He gives them a key, only instructing them to run with it. When Balthazar sends them through the window, Sam and Dean crash into an alternate universe where they are known as Jared Padalecki and Jensen Ackles, actors playing the roles of Sam and Dean Winchester on a show called Supernatural.

Sam and Dean find it difficult to grasp their lives as a TV show, the two not being brothers or even friends, Castiel being a normal actor named Misha, or even Jared's wealthy mansion and wife named Genevieve, who they mistake for Ruby. Despite this, Sam would rather live back in their own reality, where Dean is his big brother.

The brothers return back to their world, only to be confronted by Raphael, in a new meatsuit. He takes the key, only for Balthazar to intervene, saying the key will not do him any good. He used Sam and Dean as a diversion to find his weapons and hand them over to Castiel, who gave the ultimatum to Raphael, to back off or die. Castiel brings the boys back to Bobby's place saying it was Balthazar's plan, and apologizing for it.

Afterwards, Sam, Dean, and Bobby all track leads for the Mother of All, Eve. The latest monster attack leads the trio to a cannary in Ohio. While there, they team up with an old friend, Rufus, and run into the remaining Campbells: 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 of some sort, who takes possession of their body and kills anyone that is around them. It first possesses Dean, who shoots Gwen. It later possesses Samuel, who is shot by Sam because he was threatening the wall in his head, and was getting ready to tell him about his soulless year.

Sam is cuffed for safety measures, but when Samuel attacks, still possessed by the Khan Worm, he uses a short circuit to check to see if anyone else is possessed by the worm. Sam, Dean, and Rufus aren't possessed, and Samuel is dead. A possessed Bobby kills Rufus, and is later knocked out by Dean only to be interrogated and almost killed, which Sam could not bear to watch.

Sam and Dean wake up from what they call the weirdest dream, in which they rode in a Mustang, where Bobby was married to Ellen Harvelle, even where Dean wins at rock-paper-scissors. Castiel appears and tells them that it wasn't a dream, but it was all an alternate reality, in which Balthazar unsunk the Titanic, setting up a butterfly effect. However, Castiel changed the reality back when Fate threatened to kill Sam and Dean.

Sometime later, 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 he killed a Phoenix. He suggests a plan to head back to 1861 to hunt the Phoenix and bring back the ashes. Sam is a bit uncomfortable with the plan, but goes through with it anyway. He sets out to find Colt, who he finds is now retired, and doesn't care about the Phoenix. However, after proving himself a resourceful hunter, Sam returns to Sunrise with the Colt, which Dean uses to kill the Phoenix. They return without the ashes, but a delivery was made to Sam from Colt himself, sending his broken cell phone and the ashes of a Phoenix.

With these ashes, Sam, Dean, Bobby, and Castiel all load up and head to Oregon, where they find out that Eve is currently populating the small town with new monsters, which Dean dubs as "Jefferson Starships". Sam and Dean, however, find two young orphans locked up in a police station, and feel the need to take them to safety, much to Castiel's irritation.

However, once the boys confront Eve (who has taken their mother's form), she slipped that they were infected by the perfect beast, who went right past them undetected. 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 demons or monsters, and persuades Eve to bite him. A restrained Sam tries to attack, but Eve is killed after biting Dean and discovering Phoenix ashes from Dean's bloodstream.

Sam, Dean, Bobby, and Castiel all check out the home of the two orphans, only to find their dead bodies trailed with sulfur. This confirms to them that Crowley is alive, to which Castiel leaves immediately to check up on. Sam and Bobby suspect that Crowley faked his death, and that Castiel purposely meant to burn the wrong bones.

Dean tries to remain loyal, but Sam and Bobby remain suspicious, despite their hopes of being wrong. Castiel gives himself away, however, after using Bobby's exact pop culture reference ("Superman going to the dark side"). The three decide to 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. Instead of thanking him, Sam jumps to the conclusion that he might have brought him back soulless on purpose. However, when Crowley seizes the building, Castiel orders them to leave.

After Castiel arrives at Bobby's place to make them understand one more time, Bobby noticed he stole a journal that suggested that horror writer H.P. Lovecraft had attempted to open a door to Purgatory, as he has made several mentions of opening a door to another dimension. Sam immediately recognizes him by name, but Dean does not catch on. Their discussion is interrupted by a phonecall from Ben, who tells Dean that demons are coming for them. 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, while Bobby tries to get one step ahead of Castiel. Balthazar refuses to help at first, but later relents by revealing Castiels location. The brothers split up to find the two, with Dean eventually finding them, and Sam is locked up after being knocked unconscious by demons. He is later freed by Dean, and drives a dying Lisa, Ben, and Dean to the hospital. Once Sam finds out that Dean wiped their memories of him, he starts to voice his disapproval, but Dean threatens to break his nose if he mentions them again.

Sometime later, Sam is seen running from the police, and takes refuge in a bar, meeting the bartender Robin. She first asks him to leave, but Sam pleads to stay for only a few minutes. She asks for his name, for which he tells her he does not know, and that he cannot remember anything. However, he starts to remember bits and pieces. Starting with finding an H.P. Lovecraft book, he searches for the Nite Hotel after having a vision of living there. Robin tags along out of curiosity.

He finds what he assumes to be his room, jams the door open out of instinct, and after examining the place, has another vision which reveals him with Dean and Bobby looking for Eleanor Visyak, who called and told them to meet her in an alley. They find her dying, telling them that Castiel and Crowley tortured her and now have enough to crack Purgatory wide open. As she dies, Castiel appears and apologizes. When Dean throws an arguement, Castiel simply states he doesn't care what they think. He pleads for them to go home and let him stop Raphael. When they stay where they are, Castiel gives them a reason to go home, saying he will save Sam once it is over only if they stand down. He teleports behind Sam, touches his head, and tears down the wall in his head. From this, all he uses for granted is his name and Bobby's, which he finds in a directory with an address.

Sam takes the keys to the Impala, and is about to leave before Robin warns that he might not like what he finds. Before she can continue, Sam shoves her out of the way of a gunshot. He then spots the shooter: "soulless" Sam. He then takes Robin and drives off. She asks who the shooter was, but Sam lies and says he didn't get a good look. Robin suggests they turn around and talk to the police, but Sam refuses and would rather find his friends. Except, he comes to a stop once a bright light (Dean turning on a flashlight and hovering it over an unconscious Sam's eye) shines.

He notices that it's now daytime, much to Robin's irritation. She is about to leave, but Sam tells her to get in the car, as he heard the snap of a twig in the forest. He finds the arsenal of weapons in the trunk, takes a handgun and shotgun and searches the forest, only to run into "soulless" Sam once again. He tells him that this is all in his head, and that he and Sam are both pieces that he shattered into once the wall came down. He tries to take control of his body by attempting to kill him once again, but "soulful" Sam emerges as the victor. "Soulless" Sam warns him that he has yet to face "the other one". He then integrates with "soulful" Sam, giving him the memories of his soulless year. Sam returns to the car, now remembering Robin as a victim to a Crossroads demon. Sam, soulless, shot Robin first before killing the demon holding her as leverage. He apologizes to her, but she says he'll be even more sorry soon.

Sam arrives at a grim version of Bobby's house, and finds the other Sam sitting in the kitchen. He asks which one he is, and he reveals himself, tortured and scarred, as the one who remembers Hell. He pleads for Sam to turn around, but Sam insists on putting himself back together. He has to know what happened in the cage to wake up. "Tortured" Sam asks why it's so important to him, to which Sam replies he is not leaving his brother out there alone. "Tortured" Sam refuses to put up a fight, wishes him luck, and gives him a knife for Sam to stab him with. He kills "tortured" Sam, and integrates with him, now remembering Hell.

He wakes up and takes the gun Dean left for him, and later arrives at the address Dean said they were going to be. He is damaged from the memories of Hell, but continues on to Crowley's headquarters. He walks in when Castiel returns and destroys Raphael. As Castiel claims he has no family, Sam picks up an angelic blade and stabs him in the back. Castiel simply pulls the blade out of his back, greeting Sam, 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. Sam, Dean, and Bobby look on in horror.

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. 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 problems Sam decides to stay behind on hunts. He is soon tricked by Lucifer, and brought to a warehouse by him. 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 did when he was a teenager. So he leaves Dean 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. So he lets her go again. 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. In order to help deal with hell, Sam begins to take up a healthier lifestyle and begins jogging. 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 separate from Dean for a week before they are reunited in Lily Dale. Sam is still angry with Dean, but 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.

In Season 7, Time For A Wedding, Sam is drugged with a love potion and marries Becky. When he comes back to his senses, Becky knocks him out and ties him to a bed. Sam convinces Becky to let him go and help them trap Guy. In How to Win Friends and Influence Monsters, Sam notices that the burgers are changing people and turning Dean into an "idoit". He, Dean and Bobby find out that its a Leviathan plot.

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 as Emanuel. 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 board game without Dean to check whether Bobby's ghost still haunts the brother to no result.

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.

Deaths
Throughout the course of the series, Sam has died once and has been resurrected by the Crossroads Demon. Dean paid the ultimate price with his soul, only to be brought back from hell by self-proclaimed Angel, Castiel. 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".
