Then, I got to thinking that Dean wanted to truly believe that Cas was gone and not in there anymore because he couldn't stand the thought of Cas doing those things.
Goodness, I hope so. I was thinking that, too, because if not - Dean is completely OOC.

This episode absolutely killed me dead. It was better than I anticipated, but the last five minutes were just too much! Too many twists! My emotions!!!! Real!Cas better come back. And Dean better give that little nerdy angel that hug he's been needing.
