<P> Twenty - two years after Mary's death, John disappears while on a hunt, forcing Sam and Dean to reunite in an unsuccessful attempt to find him . Sam returns to the life of a hunter after Azazel kills his girlfriend . John reluctantly chooses to avoid his sons throughout most of the season while he investigates something, eventually reuniting with them in the episode "Shadow ." However, the demonic Meg Masters attacks them and reveals that Azazel is after John . After escaping from Meg, the brothers split up from their father to keep him from the demons . When vampires murder his old mentor and steal the Colt--a mystical gun capable of killing anything--John teams up with Sam and Dean in "Dead Man's Blood" to retrieve it . Because demons cannot be killed by conventional means, they hope that the Colt will be effective against Azazel . In response, Meg begins killing the Winchesters' friends in "Salvation," and threatens to kill more unless they deliver the Colt . John is captured after trying to give her a fake gun, and reveals himself to be possessed by Azazel when the brothers come to his rescue in the first season finale "Devil's Trap ." However, he manages to resist the demon's control . Despite John's pleas for Sam to shoot him with the Colt, Sam cannot bring himself to do so and allows Azazel to escape . As the Winchesters flee in Dean's Impala, a demonically - possessed trucker crashes into them . </P> <P> In the second season premiere, "In My Time of Dying," Sam and John awake in the hospital with only minor injuries, but a dying Dean is comatose . John secretly summons Azazel, and seems to know what the demon's plans are . He then makes a deal to save Dean, giving up his life, soul, and the Colt . Before dying, John instructs Dean to kill Sam should he become evil . The fourth season episode "On the Head of a Pin" reveals that the demon Alastair tortured John in Hell for over a century, with John refusing the demon's offer to stop if he himself would torture someone else . His soul escapes from Hell in the second season finale "All Hell Breaks Loose, Part 2" when a gateway to Hell is opened . He saves Dean from Azazel, and distracts the demon by temporarily forcing him out of his host, long enough for Dean to kill Azazel with the Colt when he returns to his usual body . John then gives Sam and Dean a loving smile before becoming engulfed in a white light . However, the fifth season episode "Dark Side of the Moon" suggests that he might not be in Heaven . </P> <P> Actor Jeffrey Dean Morgan deemed John a "tormented soul," motivated by an "equal combination of revenge and protecting his sons ." Following the death of their mother, Sam and Dean became secondary to John's quest of killing the demon responsible, although Morgan believed that this aspect changed once John began spending more time with them again . Though he thought that John was not the world's best dad and "definitely made a lot of mistakes," the actor noted that "he did things, even when they were wrong, for the good of his sons ." John Kubicek of BuddyTV felt that this reasoning extended to John's decision to hide the truth from Adam to protect him . Kubicek also suggested that John became involved in Adam's life to achieve "some level of normalcy" as a father, an opportunity he had previously lost following the death of Sam and Dean's mother . Overall, Morgan felt that John "loved those kids more than he loved his own life," with the character's demonic pact with Azazel serving as "his way of finding redemption ." </P> <P> Regarding his portrayal of the character, Morgan commented, "I played him with extra angst . I think what was on the page, what I foresaw--not knowing where it was going, because no one would ever tell me anything--there was always a lot more going on in his head than he was going to show anybody, including his sons . Because, indeed, there was a lot more going on ." Kripke later confirmed this, stating, "It's our view that John knew everything the producers of the show know . John knew stuff we're not even ready to reveal, that won't come out for a couple of seasons . He was an awesome hunter, and by the time he showed up in' Dead Man's Blood,' he knew it all ." </P>
