Dean Winchester - Season 6

Season 6

The sixth season picks up a year later. Keeping the promise he made to Sam, Dean gives up the life of hunting and now lives with Lisa and her son Ben. After Dean became poisoned by a Djinn, begins hallucinating his worst fears. Sam saves Dean by injecting him with an antidote and later wakes up seeing Sam alive and well. Sam reluctantly tells Dean that he has been back for nearly a year while hunting with their grandfather, Samuel. After helping kill the Djinns, Dean declines returning to the life of hunting and decides to continue living with Lisa and Ben in order to keep them safe. Lisa tells Dean to return to the life of hunting and she and Ben will be there when he gets back.

In "Live Free or Twi-Hard", Sam and Dean investigate cases of missing girls who are obsessed with vampires. They stake out a bar that eventually leads them to the cause. Dean later crosses paths with a vampire that turns him into one. Expecting to have to be "put down", he goes to visit Lisa, but almost loses control while talking to her and flees. After being cured, he realises that Sam may possibly have let him be turned; but to an unknown end.

In "You Cant Handle the Truth", Dean and Sam investigate a town in Illinois, where everyone who has wished for truth not only received his wish, but has become insane and committed suicide. While initially believing that the Horn of Truth, an angelic weapon, is the culprit, Sam discovers the summoning ritual to Veritas, the pagan goddess of Truth. However, Dean unknowningly invokes her and is forced to deal with harsh truths from everybody; including Lisa, who calls about the events of last episode and ends up telling him not to ever come back. Questioning Sam, he believes he gets the truth from him about why he didn't help keep him from being turned, but when Veritas captures them on their raid of her property, she declares that Sam is inhuman, as no human is immune to her aura of truth. The brothers manage to dispatch her, but Dean holds Sam at knifepoint, demanding the truth. Sam admits his lack of emotion and fear, but Dean doesn't accept it and beats him unconscious. Dean learns from Castiel that Sam has no soul, also that Crowley was the one who brought Sam back from Hell. Crowley also says that the only way to get Sam's soul back is to help him find Purgatory. Dean and Sam attempt to capture Crowley to force him to give back Sam's soul. Crowley tells them that not only can't he get Sam's soul but also that Sam's soul has been tortured endlessly by Lucifer and giving Sam back his soul would leave him useless. Once learning this, Castiel kills Crowley, so Dean goes to see Death to have him bring back Sam's soul. Death agrees but only if Dean becomes Death for one day and never takes off his ring. Dean fails, but Death still agrees to return Sam's soul, since Dean learned about messing with the natural order.

With Sam's soul restored, Dean and Sam return to hunting, attempting to track down Eve- the 'mother' of all monsters- after she is released from Purgatory by dragons, but Dean becomes suspicious of Castiel after he discovers that Crowley is still alive despite Castiel allegedly torching Crowley's human bones. After Dean is forced to have Ben and Lisa's memory of him erased, he confronts Castiel about his actions, but is unable to stop Castiel from absorbing the souls of Purgatory and becoming the new God.
