4.18 The Monster At the End of this Book... I am stupidly excited for this episode.
A VERY META SUPERNATURAL - Sam (Jared Padalecki) and Dean (Jensen Ackles) are shocked to discover a series of comic books titled “Supernatural” that accurately detail their lives as demon hunters. They track down the writer, Carver Edlund (guest star Rob Benedict), who explains he has visions of the brothers that he then turns into comic books. Chuck reveals that Lilith (guest star Katherine Boecher) is coming and she has a plan for Sam. Mike Rohl directed the episode written by Julie Siege.
