Task: Question Generation
Input (English): 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.
Output (English): do they ever find the dad in supernatural?
