Sam and Dean

Sam and Dean have always had a great brotherly relationship. They are both protective of each other and will die for another.

Their relationship has changed throughout the years but they still travel and work together. This relationship also begins to develop as one of the show's main plot lines.

Background
Dean is the older to Sam and was always told from a young age to "watch out for Sammy". When the demon killed their mother, it was Dean who carried baby Sam out of the house. Dean is like Sam's protector and Dean views himself like this. So when their father John Winchester went out hunting, Dean would watch over Sam. So Dean would basically cook and protect Sam while their father was out. There was one time though when Dean left Sam alone to play some games. When Dean got back, there was a Shtriga standing over Sam. Dean pulled a gun out, but didn't shoot. Then their father showed up and got rid of the creature. He also yelled at Dean for not watching Sam. This enforced Dean's resolve to protect Sam.

As the boys get older, Sam starts asking questions about what kind of work their dad does and why they always have to move around. Dean lies to Sam and makes a remark. Dean tells Sam their Dad is a Superhero. Sam continues on by asking if its because of mom. Dean gets angry and leaves. He comes back later and gives Sam 'dinner'. Sam reveals to Dean that he found Dad's journal and asks if its true. Dean tells Sam its all true (except for Santa) and how Dad fights these monsters. Dean essentially is the one shows Sam the truth about the world and all its supernatural creatures. Realizing Dad is probably not coming home because of the job, Sam goes to bed upset. Dean feels sorry for his brother and tries to make it up to him by stealing presents from other home. Much to his luck, its all chick presents. Sam thanks Dean anyways and gives him the necklace he was going to give dad. This necklace Dean wears till Season 5.

Sam and Dean also go to high school together for one year (Dean in Gr.12, Sam in Gr.9). Dean displays his protective nature again when Sam gets picked on by a bully in Truman High. Dean threatens to tear the kid's lungs out, but Sam stops him. Dean though wonders why Sam didn't take this guy out (due to their combat training). Sam doesn't want to be the weird kid again, which appears to confuse Dean.

Sometime after that, they continue hunting till Sam wants to go to college. Sam leaves and doesn't talk to Dean for 2 years.

Season 1
"I swore I was done hunting for good. Come on, it wasn't easy, but it wasn't that bad. Yeah? When I told Dad I was scared of the thing in my closet, he gave me a .45. Well, what was he supposed to do? I was nine years old. He was supposed to say, "Don't be afraid of the dark." Don't be afraid of the dark? What, are you kidding me? Of course you should be afraid of the dark! You know what's out there!"

- Sam and Dean

Sam is leaving with his girlfriend when Dean pops in to get Sam to join him in the search for their father. Sam is angry at Dean for even thinking of asking him to go on another hunt. Sam continues on how messed up their childhood was; which Dean appears not to have a problem with. Sam does give in though and joins Dean on the hunt for their father, on the condition they are back for Monday. They head towards dad's last case, only to find he is no longer there. With that fact they continue to work on the case. During which they have their first (on screen) run in with the cops. Sam gets angry when Dean doesn't show the cops any respect, and stomps on Dean's foot to get him to shut up. Dean follows up by hitting Sam's head. They finish the case and Sam heads home much to Dean's disappointment (Dean wants everything to go back to the way it was before Sam went to college). Sam goes home only to find his girlfriend being burned. Dean comes and drags Sam from the apartment. Now angry, Sam heads out with Dean, back on the job.

Sam and Dean travel around looking around for their father, but the trail goes cold. Sam gets angry with this but Dean tells him that they will find dad, but meanwhile they should kill everything in their way and save people. Sam agrees, and helps Dean hunt. Dean also helps Sam deal with Jessica's death and the nightmares about her death. He tries to get Sam to open up about it, but Sam refuses. Then Sam gets a vision about their old home, and Dean gets upset with the idea of going back there. They go anyways and find the house is really haunted. So they go to cleanse the house, and during this Sam get strangled and Dean saves him (one of many). Dean is though frighten by these visions Sam is getting, but he doesn't tell Sam. It does worry Dean though when Sam gets these visions and will help Sam try stop them from coming true.

Sam is still annoyed by the fact that Dean does everything Dad tells them to do. He expresses this to Dean in Asylum when Sam gets messed up by Dr. Ellicott. Dean attempts to reason with him, but its no use and Dean knocks Sam out for his own good. Once the spirit is defeated, Sam wakes up, normal again, and the boys patch things up. Then they get a call from Dad and Sam wants to go after him. But their dad had given them a mission and Dean wants to follow through on that instead. So the two separate, but not for long. Sam returns when Dean doesn't answer his phone for three hours, and saves Dean.

Sam shows his protective side when Dean's life is in danger. Sam looks far and wide for a cure for Dean. Sam manages to find a faith healer who heals Dean. In The Benders, we see more of Dean's protective side when Sam gets kidnapped by some weridos. Dean teams up with an officer to find Sam.

Dean also made it his mission to get Sam laid. Sam does appreciate this but lives with it. Dean believes if Sam gets laid he would relax more and it would help him with Jessica's death. Dean tells Sam its what Jessica would have wanted for Sam. Then they team up with their father again, and Dean has to deal with their arguing. Then Sam and Dean team up to deify their father's orders, and help him get the colt. They head out after the demon. Then Sam gets a vision, and they have to separate with their father. So they go after the demon, and they head to his next target. They arrive on scene, and the demon sets the place on fire, and Sam grabs the baby. Seeing the demon is still there, Sam tries to go back in, but Dean stops him. Sam is angry, but Dean believes life is better than revenge.

Dean proves these beliefs further when they go rescue their dad and he brings the colt despite Sam telling him not to. Dean uses the colt to kill a demon that is beating Sam. Sam thanks Dean for saving him, but is still angry Dean brought the colt. Now escaped, they hide in an empty house, and Dean realizes their dad is not "dad". When Dean tells Sam this, Sam believes him over "dad". This proves Sam's trust in Dean. When their dad is found to be the yellow eyed demon, Dean begs Sam not to kill him, and Sam doesn't.

Season 2
After the accident, Dean is put into deadly coma, and Sam is only one who believes in him. Its Sam who realizes Dean spirit is around. So Sam communicates with Dean and helps Dean realize hes being hunted by a reaper. Although Dean does not remember this after John made a deal with a demon to get Dean healed. Before John died, he tells Dean one final thing about Sam.

Following their father's passing, Sam and Dean are dealing with his death in different ways. Dean begins to fix up the Impala and Sam shows him a message from one of dad's old contacts, Ellen. There they find a job and head out. Dean wonders why Sam is suddenly all for hunting now. Sam tells Dean, its because its what Dad would have wanted. Dean is confused and angred by this because of the relationship Sam and John had. Sam tells Dean the reason is because dad is dead. So which is why Sam wants to do the job. Once they finish the job, Dean asks Sam if Sam really meant it when he said he wasn't going to go to college anymore. Sam replies yes. Once back at Bobby's, Sam apologises to Dean, and says that hes not handling Dad's death well. Sam leaves and Dean wacks the impala with a crobar.

Sam and Dean hit another speed bump when they meet Gordon Walker. Dean instantly bonds with him, because with Gordon he doesn't need a brave face (Which he believes he needs with Sam). Though his beliefs get tested when Sam tries to convince Dean to leave the vampires alone because they weren't hurting people. In the end, Dean chooses Sam over Gordon.

Later on, they run into another special child, and Sam believes this guy to be a killer, but Dean believes it not to be so. Though, Andy using his power, makes Dean tell the truth about his feelings on Sam's powers. Dean gets even more worried when Sam is immune to a virus that wipes a town in Croatoan. Before he known Sam was immune to it, Dean refused to kill Sam. Sam begs Dean to do it, but Dean refuses. Dean tells Sam hes tired, and wants it to end. Once they leave town, Dean finally tells Sam what dad told him. Sam gets angry and leaves. Dean follows and saves Sam when Gordon attacks, but only gets knocked out himself. Sam comes and saves him.

They go back hunting together again, and Dean no longer carries his father's words as a buden. But now Sam does, he expresses this when he gets drunk and makes Dean promise to kill him if he turns in a monester. But Dean can't do it. In Born Under A Bad Sign, Sam goes missing and returns with memory loss and a murder on his hands. Dean refuses to kill him, and he later figures out Sam was possesed by a demon. How he knew is because he strongly believed Sam would never do anything like this.

In Tall Tales, Sam and Dean get into their first (on screen) fight. This is because Sam believes Dean took his laptop and Dean believes Sam messed with the Impala. Once they realize it was really the trickester doing this, the two apologize to each other. Later on, Sam and Dean come across a werewolf case and they find it is a girl named Madison, who is unware of her other persona. Unfortunally, Sam has fallen in love with her and when they realize they can't help her, Madison asks Sam to kill her. Poor Sam is torn at what to do, and Dean feels for his brother. Dean offers to do it, but Sam does it because she asked him to. So as Sam goes to shoot her, Dean crys for his brother's sake (very emotional moment for both of them).

Then the real trial comes when Sam gets kidnapped from the dinner by a demon. Dean calls in Bobby to help him look, meanwhile Sam is in an abandoned town with the other special children. Andy sends Dean a clue to where Sam is. While waiting for Dean, Sam tells Jake Dean and how Dean tells him everything is going to be fine. Sam continues on how Dean can't always be there. Dean later arrives in town and finds Sam, but only to witness Sam get stabbed in the back. Sam dies in Dean's arms. While Sam dying, Dean telling him its going to be okay and that hes gonna patch Sam up. With tears in his eyes, he screams, "SAMMMMMMYYYYY!!!"

Its been a week since Sam died, and his body is laid in the bed in the next room. With Sam dead, Dean doesn't want to live without him. He doesn't eat much, and only drinks. Bobby attempts to get Dean to work, but Dean yells at Bobby to leave. He also tells Bobby that hes given the world enough (gestures at Sam) With Bobby gone, Dean talks to Sam's body about its his responsibility to take care of Sam and he failed. With no other option, Dean makes a crossroad deal to bring Sam back in exchange for his soul in one year. Now Sam's back and Dean is thrilled to see his brother up and around. Dean tells Sam that Bobby patched Sam up. Sam believes this and wants to get back to work. Dean isn't too thrilled but goes with Sam. At Bobby's, they figure out Yellow Eye's plan and head to Hell's Gate. There Dean watches his brother kill Jake, and Azazel tells Dean what if Sam is not 100% Sam. This worries Dean.

After they manage to close the gate, Sam confronts Dean about what happened. Sam figures out that Dean made a deal to bring him back from the dead, and asks how long. Dean tells Sam, "1 year". Sam reponds by says its his turn to save Dean.

Bobby, later, calls in them in for a job, which they later find out is the Seven Deadly Sins. After it, Sam tells Dean hes had enough of playing mister nice guy and why doesn't Dean even try to get out of the deal? Dean tells Sam, because if he does, Sam drops dead. He continues on by saying that when John sold his soul for Dean, he already disrupted the natural order; at least now something good will come out of. Dean finishes by telling Sam hes tired and its done. So Dean says "So what’s say we kill so evil sons of bitches and we raise a little hell?"

In return, Sam shoots her in the face.

Sam also confronts Dean on his Kamikaze moves. On how Dean is valuing his life, and that Sam know how Dean really feels. Sam knows Dean is afraid, and wants his brother back. Realizing his action affects his brother, Dean agrees and sets up a defense against the now vampiric Gordon in Fresh Blood.

With his year ticking away, Dean wants to have Christmas. Due to unpleasant memories, Sam rather not. But after being almost eaten by Pagen Gods. Sam changes his mind and has Christmas his brother wanted. They even get each other presents (Sam got shaving cream and Porn. Dean got oil and chocolate). With this in mind, Sam takes steps towards becoming more like Dean. This is seen when they encounter witches and Sam agrees with Dean that they need to be killed. Although Sam is not totally ready for Dean to die yet. When a hex bag is placed in their motel room, Dean starts coughing up blood and Sam goes after the witches with the colt. Dean also finds out that demons were originally human souls, and in Dream A Little Dream Of Me, Dean finally agrees to help Sam in the search to find a way out of his deal.

While looking for Bela, Sam and Dean run into the trickster in Mystery Spot. Here Sam watches Dean die over and over again. This makes Sam very on edge, upset and he tries to save Dean, but nothing works. While Dean has no clue what is going on, Sam is going insane watching his brother die. Sam eventually figures out its the trickster and goes after him. But when Dean dies and its not "Tuesday", Sam goes Rambo and hunts for the trickster for months. When Sam finally catches him, Sam begs the trickster to bring Dean back.

This season we see Sam and Dean's relationship beginning to strain.

Sam and Dean are reunited 4 months after Dean's death in a hotel room. When Sam first sees Dean, he attacks right away. But Bobby stops him, saying its really Dean. Sam and Dean hug. Dean believes it was Sam who brought him back, but Sam deines this and tells Dean he wished he had though. So they go investigate who did and Dean asks Sam is hes using his psyhic powers. Sam tells Dean no, it was it dying wish. They get a name, "Castiel", before Pamela's eyes burn out. Dean decides to head out with Sam, thinking Sam would stop him. On the other Sam, also lied to Dean and went after the demons in the dinner.

After meeting Castiel, Dean believes hes lying, but Sam doesn't see it that way. Dean doesn't want to believe thet he is worth saving. Later Castiel tells Dean to stop Sam, or they will. Dean sees Sam using his powers, and realizes Sam had lied to him. Dean comes out and asks Sam if theres anything Sam wants to tell him. Sam tries to explain and Dean notices Ruby. Dean attacks Ruby, but Sam saves her. Now in the motel Dean attempts to leave, because of Sam using his power (and the fact that Sam no longer need Dean. Or at least Dean believes so). Dean believes Ruby tricked Sam into using his power, and tells Sam, " If I didn't know you, I'd want to hunt you". Then Sam gets a call, and they head out. While driving Sam reveals that he knew about Azazel bleeding in his mouth to Dean, and Dean gets angry. Sam tries to apologize, but Dean is too angry to hear.

While talking about the case, Sam believes this guy can fight off his blood, but Dean doesn't think so. Dean says "Something in his blood, maybe you can relate". This makes Sam angry and tells Dean to stop the car When the car is stopped, Sam gets out and yells at Dean. He tells Dean this is why he didn't tell Dean about his powers because of hows Deans reacting. He continues on by telling Dean that he has demon blood in him and "this disease pumping through my veins, and I can’t ever rip it out, or scrub it clean! I’m a whole new level of freak! And I’m just trying to take this… curse, and make something good out of it! Because I have to." Dean thinks about what Sam has said and agrees to talk to Jack.

So they talk to Jack, but he kicks them off his properity. So they follow him and come back only to find that Jack took the bite. Jack knocks Sam and Dean out; Sam is locked in a closet. Sam tries to talk Jack out of it, but its too late for Jack. As they are leaving Sam tells Dean hes not going to use his powers anymore, but not for Dean or anyone else. Though Sam does use his power again, much to Dean's mispleasure in Its the Great Pumpkin, Sam Winchester. Also in that episode, Uriel reveals to Sam that Dean actually does remember Hell.

So in Wishful thinking, Sam confronts Dean about it, but Dean claims to have no memory of it. But at the end Dean tells Sam he does remember Hell, and doesn't want to talk about it. This makes Sam upset due to his brother's pain and gets drunk at a bar. Dean comes in seeing his brother drunk and then see Sam go towards Ruby. Ruby gives them a job to find a girl the demons are after. Sam and Dean track Anna Milton down, but demons followed them there. After their escape Dean asks Sam why he trusts Ruby so much. Sam tells Dean his story about how Ruby saved him and taught Sam to use his powers. Then Ruby contacts them and they head towards the cabin. They find out the angels want Anna.

They find out Anna is actually an angel, and both Heaven and Hell want her. So they hide her in a building but Dean gives away their location due to Uriel threatening to kill Sam. But the Winchesters have another plan, to let heaven and hell battle it out. Once the battle is over, Dean tells Sam what Alastair meant by he had such promise. Dean reveals that 4 month is like 40 years in hell. 30 years Dean was tortured, but he couldn't take it anymore more and tortured others for the other 10. Dean tells Sam he wishes he couldn't feel a thing.

Their relationship hits another road when a siren comes between the two of them. It doesn't help that eariler that morning Sam lied to Dean about taking a phone call from Ruby, and Dean lying about just waking up. In Sex and Violence uses his power to make Sam and Dean fight each other. During the fight Sam and Dean reveal their true feeling (Dean knowing about Sam's phone calls with Ruby, and Sam about Dean being weak). Just as Dean is about to kill Sam, Bobby comes in and saves them.

In On The Head Of A Pin, Castiel takes Dean away to torture Alastair. Sam begins to look desperately for him because Sam believes Dean is not strong enough because of what happened in Hell. Just as Alastair is about to kill Castiel, Sam comes and kills (not right away) him. As Dean recovers, Sam stays near Dean's bedside in the hospital.

Later, Sam and Dean discover there is a book series about them about there called "Supernatural". Not only that, but Sam/Dean fan-fictions, which Dean expresses his disgust at. They meet the author and he later tells them Lilith is coming for Sam. Dean is shocked at this and tries everything to make sure it doesn't happen. Sam on the other hand, wants Lilith to come so he can kill her.

Everything changes when Dean finds out that Sam has been drinking demon blood. Dean locks Sam away so he can detox. Sam begs Dean to let him out and tries to explain why he was drinking the blood. Dean won't hear it and leaves. This action though, does kill Dean inside and he asks Castiel for help. Later Sam escapes and Dean follows him. At the hotel, Dean and Sam fight, but Sam comes out the winner. Dean tells Sam if he leaves, don't ever come back. Sam looks at Dean and leaves.

After the fight, both sides are hurting. Dean wants to have nothing to do with Sam anymore, but its Bobby who convinces him that Dean needs to reach out to Sam. Dean attempts to call Sam though from the angel's room, but gets voice mail. The angel play the brother's relationship beautifully, by using Dean's voice to send Sam a fake hate message. This causes Sam to go over the edge and head full speed towards Lilith. Dean, with Castiel's help escapes the room and heads towards Sam. Dean arrives just as Sam is killing Lilith. Once Lilith is dead and Ruby's betrayal is known, Sam helps Dean kill Ruby. Sam apologizes to Dean for everything and they watch Lucifer's cage open.

Sam and Dean are mysteriously placed on a plane. They start off by trying to find Lucifer. Sam tries to talk about what happened, but Dean refuses. Later on Chuck sends them the location of the Michael sword, a weapon that could kill the devil. Once there they discover Zachariah waiting for them and he tells them that Dean, in fact, is the Michael sword. Michael's true vessel. Dean realizes Michael need permission to enter his body. So to persuade Dean, Zachariah breaks Sam legs. Then takes away Sam's lungs. Despite seeing Sam in pain, Dean still refuses. To Dean's luck, Castiel arrives and save them both. As they are leaving, Dean tells Sam how hurt he is that Sam choose a demon over him, and that he doesn't know is he can trust Sam again.

Sam and Dean head to a town that is apparently infested with demons. There Dean is watching Sam's every move. First when they head out to get guns and salt. Dean wants Sam to stay behind, but Sam refuses. The next time when Ellen wants to go to look for Jo. Dean tries to get Sam to stay behind, but Sam refuses. Sam asks Dean if Dean thinks he is going to loose control the moment he see demon blood? Dean asks are you? Sam pushes Dean in anger and yells.

So once Dean gets Sam, they go after War and cut off his finger. After is over, Sam and Dean have a talk. They realize they need to seperate, due to individual problems (Sam knowing hes weak and Dean tired of looking after Sam). Sam also says they could never go back to they way they were. In fact that was the problem. So Dean continues hunting and Sam works in a bar.

They don't stay separated for long though. Dean realizes even though they are weak together, they keep each other human. So in Fallen Idols Sam and Dean put the training wheels on and try to fix their relationship. Sam walks in on Dean talking to Bobby and stating the fact that Sam started the apocalypse. Sam asks when will he be off double secret probation, and Dean asks when I say so. Sam argues this was supposed to be a fresh start. After the job, Dean tells Sam he needs to let Sam grow up and they reconcile.

So now Sam and Dean revert to a new state of normal. It different then before, but yet similar. They continue hunting and they manage to find the colt and Lucifer. So in Abandon All Hope.. they go after Lucifer but only to find that the colt does not work on him.

After Ellen's and Jo's death, Sam and Dean investigate an incident in an insane asylum. Slowly the two go insane and don't know whats real and whats not. Due to an incident, Sam gets locked up and drugged. During this time, Dean comes to visit Sam. Sam tells Dean, that Dean has always been a little crazy. Sam also mentions something about Jo and Ellen's death. Then goes on about how Dean is his brother and how Sam loves him. Later in the episode Dean saves Sam from the Wrath, and the go back to normal.

In Swap Meat it takes Dean a while to realize that "Sam" isn't Sam. They two realize the truths about each when Sam and Dean enter heaven in Dark Side of the Moon. Dean's heaven is composed of his family. Like when him and Sam lit fireworks in a field. Or even when his mother made him a sandwich when he was young. On the other hand, Sam's is composed of the moments when he was able to be on his own. This surprises Dean at what Sam considered happy moments. Sam's happy moments were not so great for Dean. They put this behind them when Zachariah finds and chases them. After returning home, Castiel returns Dean's necklace. As Dean walks to the door, he drops the necklace in the trash in front of Sam.

Dean starts to lose faith and begins leaning towards saying yes. Sam notices this beginning in 99 Problems. At the end of the episode Dean runs away and goes to Lisa's before heading to a motel. In Point of No Return, Dean has his mind up to say yes to Michael. Sam comes to his motel to try to talk Dean out of saying yes to michael, but it doesn't work. Sam tells Dean he has to stop Dean, and Dean tells Sam he can try. Sam had come prepared though, and brought Castiel. They put Dean under watch in Bobby's house. Dean manages to escape though and attempts to contact Zachariah. Castiel brings Dean back though and Dean awakens in the panic room. He tells Sam that he doesn't believe in Sam. Sam looks sad and tells Dean that he believe Dean will do the right thing. He unlocks Dean's handcuff and takes him along on Adam's recuse. Zacharian manages to corner Dean with his brothers' pain. Dean is about to say yes, when looks at Sam and sees Sam's disappointment. Unwilling to disappoint Sam, Dean kills Zachariah and escapes the room with Sam, but Adam is left behind. As they drive away, Dean apologizes to Sam and still can't believe how much trust Sam has in him.

Dean later returns this trust in The Devil You Know when he and Crowley bring Brady back to the house despite Crowley's warning not to. Dean tells Sam he trusts him and to keep calm. Sam sees Brady and gets angry, but Dean holds him back. Sam manages to lock Dean in the washroom and confronts Brady. Sam realizes Brady isn't worth it and lets Dean out. The real trouble comes when Sam suggest that he says yes to Lucifer and jumps in the hole in Two Minutes to Midnight. Dean doesn't like this idea one bit, but Sam believes this to be the only way to defeat the devil.

As Dean promised to Death, he agrees to let Sam jump in the hole. On the way there, Sam makes Dean promise not to bring him back and to go to Lisa once this is done. Basically live an "apple pie" life. Dean doesn't agree at first, but in the end, he does. When Sam has to drink the Demon blood, he asks Dean to turn away, because he doesn't want Dean to see this. Then they go confront Lucifer, and Sam says Yes. Unfortunately, Lucifer wins and Sam is gone. Dean sinks in defeat and mourns for his brother. But he doesn't give up.

Dean heads towards the showdown area for Michael and Lucifer. Dean keeps trying to reach for Sam and help Sam beat Lucifer, but his efforts appear to have no effect. Lucifer begins to beat Dean into a bloody pulp. Dean reaches up and says "I'm here Sammy". Just as Lucifer pulls for the final punch, Sam notices all the memories in the Impala. Like the army man he stuffed in the ash tray when he was a kid. With the power of his memories and his relationship with Dean, Sam overpowers Lucifer and tells Dean "its going to be okay. I got him". With this, Sam jumps in the hole, leaving Dean there. Dean keeps his promise to Sam and goes to live a life with Lisa.

Season 6
Sam saves Dean after a Djinn attacked Dean. Dean is surprised to see Sam again and gives Sam a big hug. Dean ask Sam how hes back. Sam tells Dean hes been trying to figure out who (or what) brought him back for about three weeks but gave up. Dean gets angry that Sam been back for a year now and didn't tell him. Sam replies that Dean had a good life going and didn't want to ruin it. After they face the Djinn, Sam ask Dean to join him in hunting again, but Dean refuses and goes to pick up Lisa and Ben.

Sam calls Dean in on case in Two and A Half Men. With Dean on the scene, he suggests they go to pick up supplies where Dean surprises Sam with his knowledge of baby stuff. They notice though that the baby is a shapeshifter and they bring it toSamuel's place. The alpha comes and takes the baby. At the end of the episode, Lisa tells Dean to go back hunting with Sam, but come back when he can.

Though Dean begins to notice changes in Sam. Like when Sam held him back when Castiel soul probed a young kid. Dean expresses this concern to Bobby in Weekend At Bobby's. This confusion deepens further when Sam appears to let Dean get turned into a Vampire. As a vampire, Dean notices Sam unusually calm, but Sam tells Dean is trying to keep calm in this situation. Once cleaning out the nest and getting cured, Dean gets a flashback where he noticed Sam watching him getting turned.

In You Can't Handle the Truth Dean gets a truth curse cast upon him and he attempts to use it on Sam about what happened when he was turned into a vampire. Sam tells Dean that what he thinks happened didn't. But the encounter with Veritas confirms Dean suspicions. Sam tells Dean he did let Dead get turned because he knew they had a cure and so they could find the alpha vampire. Sam tells Dean there is something wrong with him. Dean is silent and then breaks out with a punch. Dean beats Sam unconscious.

Dean enlists Castiel to help figure out whats wrong with Sam. Castiel asks Sam a bunch of questions and Sam answers. Sam can't believe Dean is having Castiel treat him. Castiel soul probes Sam and finds that Sam is missing his soul. This explains Sam's actions to Dean, and Dean asks when Sam is still even "Sam". In the end though, Sam still chooses Dean over Samuel. So they follow Samuel to a compound where they take all the captured creatures. There they meet Crowley who claims to be the one who brought Sam back, and forces the boys to work for him. Dean doesn't like the idea, but Sam promises Crowley will get whats coming to him.

Dean now knows Sam is soulless, and tries to deal with this fact. In All Dogs Go To Heaven, Dean tells Sam to stop trying to be "Sam". Mostly because this soulless version could never be the real one. In the end of the episode, Sam tells Dean the truth about how he really feels. He tells pretty tells Dean he doesn't care about anything, including Dean, but he needs Dean's help. Dean later acts as Sam's conscience in Clap Your Hands If You Believe due to the fact that Sam doesn't feel anything. Like when Dean gets kidnapped, Sam goes has sex with the hippie girl. After is though, Sam begins to wonder if he really wants his soul back, meanwhile Dean still wants Sam to have his soul.

They attempt to get Sam's soul back when Sam makes a deal with Meg Masters for help on making Crowley give Sam his soul. Dean is shocked and not too happy with the fact that hes working with demons. After Crowley reveals he can't get Sam's soul and is "killed" by Castiel, Sam tells Dean he doesn't want his soul back. Dean can't believe this and Sam walks away.

But Dean doesn't give up. In Appointment In Samarra Dean makes a deal with Death for Sam's soul. Sam still doesn't want his soul tries to look for the rings, but Dean already has it. Sam lies to Dean saying hes fine with getting his soul back, when in reality, Sam doesn't want it back. Dean becomes Death for Sam, but loses the wager. Even though he lost, Death gets Sam's soul and places it back in Sam. Dean is troubled though by Sam's screams of agony.

While waiting Dean is worried Sam will never wake up, but as Bobby and Dean are talking about a hunt, Sam appears and hugs Dean. At last, the real Sam is back. Which Dean is more than grateful for. He expresses this when he and Sam are on a hunt for Dragons in Like A Virgin. Sam though is made aware of what happened when he was soulless(thanks to Castiel) and he apologizes to Dean. Dean tells Sam it not his fault, but Sam disagrees.

Sam continues to investigate what happened during the time he was soulless and Dean does not want Sam to dig any deeper. He is afraid the wall in Sam's mind will break. In Unforgiven Sam passes out and sees a moment of hell. Sam's passing out frightens Dean and he has no idea of what to do. Sam does wake up and Dean takes him out. Dean later asks if Sam wants to talk about it and believes what Sam saw was hell. Dean tells Sam to just forget about it and don't kick the wall. Sam doesn't want to forget about it but leaves it alone. Sam and Dean continue to hunt without Sam kicking the "wall".

Then in the final hours, Sam and Dean get their relationship tested. In Let It Bleed, Sam stayed with Dean in the hunt for Lisa and Ben. He is also concerned when Dean starts torturing again. When they do find Lisa and Ben, Sam comes with Dean. Then it gets flipped when Castiel destorys Sam's wall inside his head (The Man Who Knew Too Much). This puts Sam into a comatose state and Dean gets worried. Dean stays beside Sam's bedside while waiting for him to wake up. Sam begins to move, Dean gets really concerned. When Bobby makes Dean go back to work, Dean stays by Sam's side until he can't. While leaving Dean leaves Sam the address of where they'll be. When Sam does wake up, he heads to Dean's location while he still is messed up. In order to save Dean from Castiel, Sam stabs Cas only to find out it doesn't work.

The real test of their relationship is how to deal with Sam who now remembers everything.
