Relationship with the Yellow-Eyed Demon
Sam is one of the Special ChildrenA link between Sam’s powers and the YED is first suspected by the boys in 1.14 Nightmare, when Sam discovers that Max Miller’s mother dies the same way Mary Winchester did.Sam: I mean, either telekinesis or premonitions, we both had abilities, you know? Maybe it was after us for some reason.In 2.01 In My Time of Dying we find out that John knows "the truth" about Sam and the other children like him.In 2.05 Simon Said Sam meets two other people with powers, Andy Gallagher and his evil twin Ansem.

This is revealed to have been an experiment engineered by YED, when Duane Tanner contacts him on a blood goblet to report:Duane Tanner: I don't think any more tests will be necessary... The Winchester boy, definitely immune as expected.What the experiment was for remains unknown.In 2.10 Hunted Dean reveals that before he died John told Dean that he would have to save Sam, and that if he couldn't do that he might have to kill him.In 2.21 All Hell Breaks Loose: Part One the Yellow-Eyed Demon appears to Sam in a dream, and explains that his plan is for the children with special powers to fight amongst themselves until the strongest is left to lead a demon army. He tells Sam, with his leadership qualities and hunter training, is his favorite.In the same dream, YED admits to killing Jessica so Sam would go back to hunting. He then shows Sam a vision of what happened the night Mary died. Sam sees that YED fed drops of his blood to baby Sam, and that Mary knew the Yellow-Eyed Demon. Sam does not tell Dean about this.After Sam's resurrection the Yellow-Eyed Demon implies to Dean that Sam came back changed.
Lucifer's True Vessel
Lucifer's true vessel is Sam Winchester.Consent: YesIn 5.03 Free to Be You and Me, Sam is revealed to be Lucifer's true vessel.In 5.04 The End, Dean is teleported five years into the future, it is revealed Sam of 2014 said "yes" to Lucifer in Detroit. Lucifer kills Future!Dean.In 5.22 Swan Song Sam says "yes" to Lucifer in order to force him back into Hell.It is revealed that Sam, with the aid of the Impala which resurfaced certain powerful memories, could in fact resist Lucifer; thanks to the Impala, one of his memories were triggered which allowed him to regain control of his body.Surprisingly enough, despite the weighting odds, Sam manages to absorb the memories of his experiences in Lucifer's Cage, and was able to resist them from decimating him for a period of time.
Powers & Abilities
Sam has been shown to possess talents such as telekinesis and precognitive abilities (manifesting as visions). As the series progressed, Sam has learned to further develop his powers allowing him to exorcise demons from their human vessels and eventually to kill demons.
Sam's premonitions began "about six months" before Jessica's death. Initially they only occur when he's sleeping (through dreams), but by 1.14 Nightmare they occur when Sam is awake. Sam cannot control when the premonitions occur or what they're about, and they are often accompanied by intense headaches. Sam and Dean theorize that Sam only has premonitions when they are somehow related to the Yellow-Eyed Demon. This is likely true, for Sam ceases to experience visions after the demon's death in 2.22 All Hell Breaks Loose: Part Two, which also suggests that his visions were a result of some sort of link between himself and YED.Occurrences (in chronological order):Pre-series: About 6 months before Jessica's death, Sam begins having "nightmares" - visions of her death while he's asleep.Sam has a sleeping vision about the occupants of the Winchester's old house in Lawrence being in danger.1.14 NightmareSam has a sleeping vision about the death of Max Miller's father.Sam has his first vision while awake - the death of Max's uncle.Sam has a waking vision of Mrs. Miller's death.Sam has a waking vision of Dean's death.Sam has visions of another woman being killed by the Yellow-Eyed Demon.Sam has sleeping & waking visions of other psychics, Andy Gallagher and Ansem Weems.Sam has sleeping visions of Dean killing Duane Tanner.
Sam first displays telekinesis during a moment of desperation, allowing him to move a heavy cabinet blocking his path to Dean. Sam tried to repeat this ability afterward but was unable to do so. In fact, his telekinesis did not manifest again until after he began training with Ruby and drinking her blood. By the time he wields his power again, Sam is shown to be highly adept at hurling a demon as powerful as Alastair across a graveyard with little effort. He can also maintain a grip on demons, preventing them from moving or using their powers.Occurrences:Sam moves a cabinet trapping him in order to save Dean's life.Sam throws Alastair with telekinesis after he proves immune to Alastair's own telekinesis. He seems to be able to simultaneously hold a demon telekinetically and use his exorcism powers on it.Sam uses his telekinesis to throw Lilith across a room.Sam uses his telekinesis to throw a demon across the room after he gives in to his demon blood cravings.
Sam can force a demon to leave its host through sheer force of will. Initially, using this ability caused Sam a great deal of stress and would often result in severe headaches and nosebleeds, but with time and practice he was able to exorcise a demon without these side-effects. Once removed, the demon "smoke" falls to the ground and burns a black circle as it descends back to Hell. Unless the host is already dead, the vessel will survive this process (though he admitted to unintentionally killing a few during training).Occurrences:In 4.01 Lazarus Rising we learn that Sam is now able to exorcise a demon by holding out his hand and forcing the demon to leave the possessed body and return to Hell. He was taught that skill by Ruby.In 4.04 Metamorphosis Dean finds Sam practicing his exorcism powers and brings him to promise him that he will never use them again.Sam breaks that promise in 4.07 It's the Great Pumpkin, Sam Winchester when he exorcises Samhain.In 4.20 The Rapture, Sam attempts to exorcise a demon who is attacking Jimmy Novak's family. However, he is unable to do it. Later, in the warehouse where demons are holding Amelia and Claire Novak, Sam exorcises a demon from Jimmy's wife Amelia, after drinking blood from the neck of a demon possessed human.In 5.14 My Bloody Valentine, after Sam gives into his craving for demon blood, Famine offers his demons to Sam so he can drain them of their blood. Sam refuses and instead exorcises all five demons at once before exorcising the demons that Famine has consumed and effectively defeating him.
Sam has immunities to demonic attacks that steadily expand over time. At first, Sam was vulnerable to all forms of demon powers, being easily overpowered by telekinesis from both YED and lesser demons. However, his first bout of immunity manifests after being exposed to the Croatoan virus. Sam proves immune, and is later able to survive Lilith's "light" without any harm. Though still susceptible to the telekinetic attacks of other demons (like Alastair, for example) and possession by the Meg!Demon, Sam eventually reaches a point where no demon can harm him so long as he's high on demon blood. To this end, Lilith is practically defenseless against Sam during their final confrontation.Occurrences:Sam is immune to both Andy Gallagher and his twin brother Ansem Weems mind controlling powers.Sam is immune to the demonic virus that was spreading in the town through blood-to-blood contact.Lilith turns her power on Sam after killing Dean (in the same manner she used in "Jus in Bello") Sam shields himself with his arm, and after the light dies down, he is shown to be completely unharmed, and apparently immune to Lilith's power.He is also able to withstand Samhain.Sam proves immune to Alastair's telekinesis.Lilith herself says that Sam is immune to her power.
Execution & Torture
When fueled by a certain amount of demon blood, Sam powers are strong enough to allow him to not only exorcise demons, but kill them too. Killing a demon creates the same light inside their body as when they're killed by the Colt or Ruby's knife. When killingAlastair, Sam was able to do so with ease, but Lilith required extreme concentration and will, the result of which drained him of all his powers upon completion. After consuming several gallons of demon blood in preparation for becoming Lucifer's vessel, Sam was powerful enough to kill two demons without moving a muscle. Sam is also capable of inflicting intense pain on any demon, which proves useful in torturing them for information for the agony is so great that Lilith's servant begged for death after just a few minutes of exposure.
Sensing the Supernatural
Sam has a sixth sense that allows him to detect impressions or a sense of supernatural presence. Sam describes this as a "vibe" (1.10).Occurrences:Sam is able to sense supernatural presences in the old Winchester family home.Sam was able to sense Dean's spirit during a time of great stress.
When Sam came back from Lucifer's Cage his soul was left behind which left him completely emotionless. Castiel sticks his right arm into Sam's chest and reveals to Dean that, the reason for Sam's cold/relentless behavior is because his soul is missing because of him being in hell. He has said himself that he doesn't feel anything anymore, with no remorse. The new Sam will do anything to kill monsters, even let his own brother be turned into a vampire. Sam claims that it has a few benefits that have allowed him to become a better hunter: he doesn't need to sleep or really eat anymore, he has a higher pain tolerance and was able to lie to the goddess Veritas, even though she can make all other people, even Dean, tell the truth.This soulless version of Sam has also been proved to be quite dangerous, with his lack of emotion or empathy for others makes him something of a sociopath. He doesn't seem to care about those he works with, or even his brother Dean, as he just uses those close to him to achieve his own ends. This comes to a head by the middle of season six, when Death restores Sam's soul.

They have common ground in that their families are always on the road, and they feel out of place, like freaks. They kiss. Amy's mother returns, and Amy hides Sam in a closet. Amy and her mother are both kitsune, and her mother has seen Dean and John tracking her. Amy tries to sneak Sam out, but her mother finds him and would have killed him, but Amy killed her instead. Sam lets Amy go.Sometime as a teenager (presumably): At some point in his teenage years, when living in Flagstaff, Arizona, Sam ran away from home on "Dean's watch"; he was gone for two weeks and adopted a dog, "Bones", and lived on junkfood.The next memory experience through a postcard is Six Flags, which Sam and his dog, Bones, called home when he ran away from Dean and John once.Age 18/19: Sam leaves his family to study at Stanford. See Canon Discrepancies.Age 20: Sam starts dating Jessica Moore (He tells Dean in 1.13 Route 666 he had lied to Jessica for "a year and a half" about what their family did).

Sam is 22 and about to enter law school, when Dean turns up unexpectedly at his apartment in Palo Alto. The two have not spoken for some time (see Canon Discrepancies for how long). But their father is missing, and Dean asks Sam to help find him. After a weekend of searching, Sam returns to the apartment he shares with Jessica only to find that she has been killed in the same manner as his mother.This spurs Sam to embark on a journey to find their missing father and get vengeance on the demon. While John Winchester is missing, he occasionally contacts the boys to leave them new missions to complete. The boys fend off mystical creatures such as the Woman in White, the wendigo, folklore's Bloody Mary, and shapeshifters. Through these missions, Sam begins experiencing episodes of precognition and once displays telekinesis.The season finale concludes with Sam, Dean, and their father John escaping from a clash with the Yellow-Eyed Demon in Salvation, Iowa. While Sam is driving the Winchesters to a hospital after Dean and John were hurt, a truck crashes into them, causing massive damage to Dean's Impala with the Winchesters inside.
In the beginning of the second season, Sam takes a more active role in the hunting. He tells Dean that this is what their dad would have wanted him to do. the Yellow-Eyed Demon's plans for Sam are still unknown. Dean and Sam meet with three people that John once knew: Ellen Harvelle, her daughter Jo, and their computer genius associate Ash. They assist the brothers in their hunting. In 2.05 Simon Said, Sam displays immunity to Andy Gallagher's power of mind control. He is also immune to the demonic sulfur virus in 2.09 Croatoan.In 2.10 Hunted, Sam learns what his father told Dean moments before his death: that the Yellow-Eyed Demon plans to cause Sam to become evil and use him and "children like him" as soldiers in an upcoming war. Dean was told that if he 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 2.11 Playthings. In 2.13 Houses of the Holy, Sam has a vision of what he thinks is an angel, telling him he has been chosen to kill someone evil. The angel is later revealed to be the spirit of Father Thomas Gregory. We learn in this episode that Sam has faith and prays regularly.A post-coital Madison and Sam.In 2.14 Born Under a Bad Sign, Sam is possessed by the demon which had previously possessed Meg Masters. While possessed Sam killed Steve Wandell, attacked Jo and shot and beat up Dean. It is initially difficult toexorcise as it has used a spell (signified by a brand on Sam's arm) to bind itself to Sam's body. In 2.20 What Is and What Should Never Be, Sam and Dean aren't close in the alternate reality created by a djinn. Neither Sam nor Dean had ever hunted, and Jessica is Sam's fiancee.In the first episode of the season finale of season two, 2.21 All Hell Breaks Loose: Part One, Sam is trapped in a haunted abandoned town in South Dakota with other psychics like him. It was revealed that there is demon's blood in Sam and his mother Mary Winchester knew who the demon was, much to Sam's surprise. He is stabbed by a soldier named Jake and dies in his older brother's arms just as he and fellow hunter Bobby arrive to the rescue. In the second episode of the season finale, Dean made a deal with a crossroads demon to deliver himself to Hell in one year, in exchange for Sam's life. Sam doesn't know of what happened while he was dead, and is in fact unaware he was ever dead in the first place. In the following battle to prevent Jake and the Yellow-Eyed Demon from unleashing a demonic army, Sam shoots and kills Jake, unloading over ten bullets into his body. This is the first time Sam kills a man, or someone that isn't a demon, and he seems to show no remorse. The Yellow-Eyed Demon questions Dean if he is sure that what he brought back 100% pure Sam, but this is never elaborated on. Sam figures out that he was dead, and tells Dean he'll get him out of the deal he made, no matter what.
Throughout season three Sam's quest is to find the loophole in Dean's contract with the crossroads demon in order to save Dean from going to Hell. For a while, Sam is quietly and fondly exasperated about Dean's hedonistic tendencies, but Dean's borderline suicidal behavior is bothering him a lot. Sam tries everything in his power to save Dean, he even goes as far as to summon the crossroad demon and shoot her with the Colt.He receives unlikely help from Ruby, a demon who reveals that not everybody in Hell is opposed to Sam, that in fact, there a demons who are very much behind Sam. Sam also learns, that he holds dubious fame as the "boy-king" or rather "the Antichrist," something that brings fellow hunter Gordon Walker to pick up his trail and hunt him down. In the episode 3.07 Fresh Blood Sam kills Gordon using nothing but his own two hands and a wire.A notable episode is 3.11 Mystery Spot, in which, after having lived through a groundhog-day like setting for over 100 times in which Dean is killed and Sam can't save him, Sam has to fend for his own with Dean in Hell. The episode shows what will become of Sam when Dean goes to Hell - namely a single-minded, dead-inside hull of a person.To save Dean, Sam even goes as far as to consider using a questionable scientific method which helps a homicidal doctor, Doc Bentonto stay "alive" in a Frankenstein-like body.Ruby, who claims to know a way to help Sam save Dean - but who revealed to Dean that she was lying in episode 3.07 Fresh Blood - is trying throughout the season to get Sam to embrace his demonic powers.In the season finale, 3.16 No Rest for the Wicked, Sam still hasn't found a way to save Dean, and has to watch, helplessly and powerless, Lilith sic her hellhounds on Dean and tear him to pieces.
Throughout the course of season four, Sam's activities while Dean was in Hell are slowly revealed. Sam was in despair after Dean's death, and tried to make a deal with a crossroads demon, but no demon would deal with him. He drinks to excess and acts recklessly, until Ruby makes contact with him and begins to teach him how to use his demon-given powers.Sam going through a demon blood detox.Ruby possesses the body of a comatose woman whose soul has already fled. In a short time, Sam and Ruby become lovers, and Ruby is able to shake Sam out of his depression to some extent. Together, they hunt demons and Sam exorcises them and sends them back to Hell using his powers. Sam is overwhelmed when Dean returns from Hell, but the two quickly begin fighting.Castiel informs Dean of Sam's use of his powers, leading up to a minor fallout between the brothers, as Dean tries to get him to stop using them and stop hanging out with Ruby.Sam, who is more religious than Dean, is delighted to find that angels are helping them, but is severely disillusioned in 4.07 It's the Great Pumpkin, Sam Winchester, when he finally meets Castiel and another angel, Uriel, and the angels attempt to destroy an entire town. Also a shock is that Uriel treats Sam with complete disgust, threatening to kill him as soon as Sam is no longer useful. Sam promises Dean to stop using his abilities, but quickly breaks the promise.Season four shows a colder, less emotional Sam. He blatantly lies to Dean and has also become much more accepting of collateral damage and incidental loss of human life.Finally, in 4.16 On the Head of a Pin, we find out that Sam has been drinking demon blood to fuel his powers. In this episode, he has become strong enough to torture Alastair to the point of making him reveal information (though Dean's torturing methods could not make him give any information away), and then subsequently kill Alastair.In 4.20 The Rapture, it is easy to see that Sam has become very addicted to demon blood, showing all of the signs of a drug abuser. Apparently, he has not seen Ruby in awhile, which therefore means that he has not had much demon blood. He desperately calls Ruby and drinks the last of his supply. Though previously he was strong enough to kill Alastair, a very powerful demon, now he can't even exorcise a low-ranking demon. Dean is worried about Sam because he recognizes that Sam is strung out and that he cannot use his ability. Later, when Sam and Dean go to save Jimmy Novak and his family from demons, Sam loses control and drinks a demon's blood, right in front of Castiel and Dean. This leads Dean to call Bobby Singer, and together, they lock Sam in Bobby's panic room to help Sam detox.Sam's eyes go black as he kills Lilith.In 4.21 When the Levee Breaks, Sam hallucinates while detoxing from demon blood. He thinks he is being tortured by Alastair and then he seems himself as a fourteen year old. He also sees his mother, and then thinks that Dean is taunting him and calling him a monster. Later, Castiel lets Sam out of the panic room on the angels' orders. Sam immediately takes off to find Ruby where he drinks a lot of her blood and learns that there are only a few seals left, and the last seal must be broken by Lilith herself. Dean eventually finds him which results in a major fight where Sam almost strangles Dean. As Sam turns to leave, Dean echoes John Winchester's words, saying that if Sam leaves, he should never come back.In 4.22 Lucifer Rising, Sam works with Ruby to reach Lilith before she can break the final seal. When Sam and Ruby finally reach Lilith, he kills her, with his eyes turning black because of the amount of demon blood he had to ingest. Once Lilith is dead, he learns that Ruby had been working to raise Lucifer all along. When Dean bursts into the room, Sam holds Ruby while Dean kills her with her own knife. Sam and Dean then watch in horror as Lucifer's door is finally opened.
In 5.01 Sympathy for the Devil, following Sam's actions and Lucifer's release, Sam tries desperately to redeem himself by trying to stop the devil’s plans. However, Dean and Sam temporarily part ways, leaving Sam in a normal life until he is approached by Lucifer, who appears in the form of the deceased Jess. Lucifer tells Sam that he is his true vessel, in conjunction with Dean being the archangelMichael's true vessel.Sam consents to being Lucifer's vessel.Dean and Sam reunite shortly after this and Sam does his best to rebuild his relationship with his brother although the brother’s are no longer as close as they once were and find it hard to reconnect, a fact emphasized in 5.16 Dark Side of the Moon when Sam’s version of Heaven was completely devoid of his family and involved incidents that meant he was away from the Winchester's which causes Dean to discard the amulet Sam gave to him years prior.In 5.18 Point of No Return, Dean 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.It is revealed in 5.20 The Devil You Know that Sam's good friend from Stanford, Brady, was possessed all that time and Sam has been hounded by demons from 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.Sam wrestles control from Lucifer.Sam still lives with a craving for demon blood. In 5.14 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 although he is soon 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.After discovering that Lucifer can he locked back into his Cage 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.In 5.22 Swan Song Sam finally says "Yes" to Lucifer, prior to which he consumes an incredible amount 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 (including a grade school teacher and Sam's prom date, Rachel Nave). 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 leaps into Lucifer's Cage, taking along Adam/Michael.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 Hell and pulls Michael in with him, effectively stopping their battle.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, staring in at them, is Sam.
A year after the events of season five, Sam reveals himself and reunites with Dean in 6.01 Exile on Main St. after Dean is attacked and poisoned by a djinn. Sam reveals to Dean he has been back practically the entire time and has spent the past year hunting alongside the remaining Campbells.Dean and Sam begin hunting together again in 6.03 The Third Man. However, it is immediately apparent that Sam is not the same person he was before. He is shown to be a more cold and calculating person than before and also a more efficient and ruthless hunter, particularly when he doesn't object to torturing a young boy in order to gain information about their case which horrifies Dean.When Dean confronts Sam about the fact he is acting differently, Sam denies that Hell affected him in the same way that it did Dean and that he is absolutely fine though Dean doesn't buy it.In 6.05 Live Free or Twihard when Dean is changed into a vampire, Sam is shown observing the change with a small smile on his face.Samuel Campbell confronts Sam about knowing about the cure for being turned which Sam denies ever having known and suggests that Sam actually allowed Dean to be turned to be used as a bait, something the old Sam would never have considered doing.In 6.07 Family Matters, with the help of Castiel, Dean discovers the reason for Sam's cold, relentless behavior is because his soul is missing. It is confirmed by Crowley that he was barely able to bring Sam's body back from the cage and his soul is still in there withMichael and Lucifer. Is suggested by Castiel, Crowley and even Death that Sam's soul is "mutilated" and "flayed to the raw nerve" and even if they're able to retrieve it, Sam may die from the damage done.In 6.11 Appointment in Samarra, Dean makes a bet with Death that if he could be him for a day, Death will bring Sam's soul back. Sam does not want his soul back and goes to extreme lengths to prevent this from happening, even almost killing Bobby. However, even though Dean loses the bet, Death does bring Sam's soul back and creates a mental wall within Sam's mind to deal with the memories of Hell before he forces it back into Sam's screaming body.Death returns from Lucifer's Cage with Sam's soul.Sam remains unconscious for ten days after the return of his soul. WhenCastiel exams his soul at the beginning of 6.12 Like a Virgin, he says that it feels as though it was "skinned alive," and doubts Sam's survival. Nonetheless, Sam does regain consciousness, and has no memory of the past year and a half, either from Hell or from Earth. He is overjoyed to see Dean and Bobby alive and well, and eagerly hugs them both. He is hungry, and curious to know how he has been saved. Dean chooses not to tell him what has actually happened, and Bobby reluctantly follows his lead. Sam is ready to start hunting at once, and joins Dean to investigate the disappearances of some girls under strange circumstances. Sam suspects that Dean never went back to Lisa after the Apocalypse was stopped, and when Dean tells him briefly that after a year, his relationship with Lisa did not work out, Sam is sympathetic. As the interrogate witnesses, Sam's empathy and consideration provide a stark contrast to RoboSam's methods. Sam is quick to realize that Dean is not giving him the whole truth, and prays to Castiel. The angel appears, glad to see Sam intact. Sam hides his memory loss, and from Castiel's questions realizes that he was on Earth without his soul. He hides his surprise, and asks the angel to help him remember some of the details that are fuzzy. Dean and Sam rescue the girls and defeat a dragon, and when they return toBobby's, Sam apologizes to Dean for what he did while soulless. He feels that he needs to make amends where he can, even if he is not entirely responsible.As they investigate a case in 6.13 Unforgiven in a town Sam visited while soulless, he begins to remember flashes of the missing year. He discovers the brutal way in which he dealt with the victims of an arachne, one of whom was turned and drew him back to the town. At the end of the investigation, he drops to the floor convulsing as he recalls some of the torment he endured in Lucifer's Cage. He awakes after a few minutes, remembering about a week of his experiences in the pit. Sam is sufficiently recovered to run the next case himself, and encourages Dean to follow up on a call he received from Ben. In 6.15 The French Mistake, Sam and Dean are thrown into an alternate world where Sam is an actor married to the actress who played Ruby. He lives in a mansion decorated with art of himself and owns an alpaca. In spite of the wealth he has in this world and his enjoyment of his alternate universe wife, he wants to return to his own world, where his life matters.Eve remains a focus for the brothers, and they track her during 6.16 ...And Then There Were None. They find themselves the victim of her new creation, the Khan worm, which possesses Samuel Campbell. Sam is forced to kill him, and in spite of everything, regrets that his grandfather has died. The brothers lose Rufus, but manage to save Bobby. The brothers also deal with repercussions from the angelic civil war, including Balthazar's saving of the Titanic, and the attempts by Fate to kill off the survivors. Sam and Dean agree to act as bait for her, and she is stopped when Castiel agrees to re-sink the Titanic.Sam regains his soulless memories.Eventually, Sam remembers that there is a hunter's library in the Campbell Compound, and leads Dean and Bobby there in search of a way to kill Eve. They discover that phoenix ash is her weakness, and that Samuel Colt reported the death of a phoenix in 1861. They arrange for Castiel to send them back in time. Dean tracks the phoenix while Sam goes to find Samuel Colt. He proves he is from the future using his Blackberry, and impresses Colt with his knowledge, but the older hunter is not interested in helping, as he is 'retired'. Sam reminds him that hunters cannot retire, and persuades him to give up the Colt so that Dean can use it to kill the phoenix. They do not get the ashes, but Samuel Colt manages to send a package to Bobby's house in the present day using the information from Sam's Blackberry.Sam, Dean, Bobby, and Castiel go in pursuit of Eve armed with the ashes. The find a city that Eve has peopled with monsters in 6.19 Mommy Dearest. Together they manage to defeat Eve after she drinks the phoenix ashes when she bites Dean, but discover thatCrowley is alive. Sam and Bobby both suspect that this can only have been because Castiel is in league with Crowley. They are proved right in 6.20 The Man Who Would Be King. Sam, Dean, and Bobby try to find Crowley on their own, but are blocked by Castiel, who has, as they discover been spying on them. They trap him in a flaming ring of holy oil to interrogate him. Castiel tries to defend himself, revealing that he resurrected Sam. Sam is shocked, and suspects Castiel of having deliberately left his soul behind.Sam regains his memories of Hell.Crowley strikes at the brothers in 6.21 Let It Bleed, kidnapping Lisa and Ben. Dean tortures demons to find them, and Sam tries to keep him calm. He offers to take over, but Dean refuses. Sam, though Dean suspects Castiel's complicity in the kidnapping, prays for Castiel's help. Castiel listens invisibly. The brothers later summon Balthazar, telling him about Castiel's involvement with Crowley. The angel is surprised, though he lies to cover it. He later gives them Lisa and Ben's location. The brothers go to rescue them, but Sam is caught, and Dean must complete the mission alone. They rush an injured Lisa to the hospital, where she is expected to die, until Castiel appears and heals her. Dean then has him take away all their memories of the Winchesters.
