4x07 It's the Great Pumpkin, Sam Winchester

It's a few days before Halloween, and Sam and Dean investigate two mysterious deaths in a small town. The brothers find hex bags and deduce a witch is sacrificing people to summon a dangerous demon named [Πρέπει να είστε εγγεγραμμένοι και συνδεδεμένοι για να δείτε αυτόν το σύνδεσμο.]. Castiel arrives in town and tells Sam and Dean that the freeing of Samhain is one of the seals that will lead to freeing Lucifer. Castiel brings a specialist angel named [Πρέπει να είστε εγγεγραμμένοι και συνδεδεμένοι για να δείτε αυτόν το σύνδεσμο.] to smite the entire town but is convinced by Dean not to and to give the Winchesters a chance to stop the witch. Samhain is freed despite their best efforts and after losing Ruby's Knife, Sam is forced to use his powers to exorcise the demon, stopping the rise of the ghosts and demons he was causing, but the seal is still broken. Uriel warns Sam that the next time he uses his demonic powers, Uriel will turn him to dust. Castiel reveals that his true orders were always to follow Dean's orders to test his leadership under battlefield conditions. Castiel warns that hard times are ahead and he doesn't envy Dean, but also that he does have doubts about his orders and what he has to do.
