Uriel and Castiel forcibly recruit Dean to torture the captive Alastair. They need to find how, who or what is killing angels as one of another 66 Seals in which both Dean and his former captor play mind games against each other to break one another down. Sam is forced to call upon Ruby to help him find Dean before he emotionally cracks, while the rouge angel, Anna Milton, also returns to ask Castiel where he stands on his position as an angel of the Lord - does he obey all heavenly rules without question?
