Also enjoyed the episode, glad the whole Sam possession thing is behind us, I didn't want this to drag out the entire season. Interesting bit of dual possession inside Sam. Cool seeing that.
Got some more answers about why God possibly left, he was so upset at Gadriel, he left. That was a long time ago, so wow. If that's the reason of course, but that's what Castiel said.
Crowley doesn't seem so evil anymore, in fact, it looks like they are setting him up to be on the good team, at least, as long as it suits his interests. (watch the preview for next episode) He obviously will want to get rid of Abadon, so while the boys and him share that goal, he'll help help. After that, will be interesting.
I love the "Three Amigos" Dean, Crowley and Castiel
Poor Kevin, I also can't believe they actually killed him, and apparently Metatron "flipped a switch" in heaven, so no more prophets
So Dean is on a mission, kill Gadriel. I have a feeling Gadriel will end up turning on Metatron though. We will see.
