Later, Castiel appears to Dean in a dream and reveals that "The Rising of the Witnesses" is one of many seals, which are being broken by [Πρέπει να είστε εγγεγραμμένοι και συνδεδεμένοι για να δείτε αυτόν το σύνδεσμο.] in order to bring on the [Πρέπει να είστε εγγεγραμμένοι και συνδεδεμένοι για να δείτε αυτόν το σύνδεσμο.], in which [Πρέπει να είστε εγγεγραμμένοι και συνδεδεμένοι για να δείτε αυτόν το σύνδεσμο.] the fallen archangel will walk the earth free.
