what episode do dean and sam meet castiel
Castiel (Supernatural) At the end of the third season of Supernatural, main character Dean Winchester is in Hell after being killed by the hellhounds of the demonic antagonist Lilith. In the season four premiere "Lazarus Rising", the angel Castiel is introduced as the one who brought Dean back from Hell and resurrected him. Because merely perceiving his actual form typically results in blindness,[2] he takes a human host – James "Jimmy" Novak,[3] a "devout man" who prayed for it – to communicate with Dean, and tells him that he has been brought back because God has work for him.[2] Lilith is breaking the 66 seals in order to free Lucifer, and Dean must stop her.[4]
