Task: Question Generation
Input (English): Azazel (Supernatural) -- Azazel's last appearance chronologically is in the second season finale ``All Hell Breaks Loose'', where he kidnaps Sam and the other young adults that he had infected. He visits Sam in a dream, and reveals that his ``special children'' must fight to the death to determine who will lead his army. Although Sam is the demon's favorite, the super-strong Jake Talley becomes the winner. As Dean sells his soul to another demon in exchange for Sam's resurrection, Azazel gives Jake the Colt and coerces him to travel to a cemetery in the middle of a giant devil's trap. Though Sam and Dean, along with other hunters, attempt to stop him, Jake uses the Colt as a key to unlock a mausoleum there. This action briefly opens a gateway to Hell, releasing Lilith and hundreds of other demons. With the devil's trap around the cemetery now broken, Azazel confronts the Winchesters and easily overpowers them. However, John's soul escapes through the Gate, and distracts Azazel long enough for Dean to shoot him dead with the Colt.
Output (English): do sam and dean find their mother killer
