Okay, Castiel lost his damn mind, and I'm a bit thrown off by the whole "I'm the new God" thing. Sounds more like he took over Lucifer's role, but I'll wait and see where this is going. I actually don't know how to feel about this. I don't want a show centered around Castiel, and they really did a 180 with his character. It could be interesting, though.
I did however, love all of the Sam pain. I wanted to hug my poor baby through the whole episode.
