Title: Lazarus Rising (Supernatural)
Passage: The episode is set four months after Dean goes to hell in No Rest for the Wicked at the end of season 3. The narrative follows the brothers Dean (Jensen Ackles) and Sam Winchester (Jared Padalecki) as Dean returns from hell and tries to discover how he came back to life. The episode is perhaps most significant for introducing the angel Castiel (Misha Collins), who would become the longest surviving regular character.
