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?

Did You Know?
While Dean is torturing him, Alastair remarks, "It's your professionalism that I respect." This is the same line used in Little Shop of Horrors, spoken by the dental patient in response to the sadistic dentist who is trying to cause him pain. However, the dentist didn't know that the patient was a masochist who was enjoying what the dentist was doing. By referencing this, Alastair may have been trying to indicate that Dean's torture attempts were not having the desired result. See more

[With a snarky smile
Well, get some donuts while you're out.
