Well, hmmmmmm......
Iiinnnnteresting. What I took away from this episode:
1. Angels are still Grade A dicks.
2. Castiel got to do a little kinky role-playing while he was crazycakes. How many people were in that menage a whatever? Castiel, Jimmy Novak, Meg, Meg's host, and possibly part of Sam?
3. Dean is a secret Samwise Gamgee fan.
4. Dean either a) has an incredible amount of unwavering faith in those he cares about or b) is addicted to abusive relationships with possessed people. But apparently he has a knack for bringing his possessed loved ones back from the Dark Side.
5. I assume Castiel was riding the bus because he turned off his "angel radar" to drop off Heaven's grid, but he certainly seemed to be enjoying his human moment. I'm going to make a prediction here and say that one day Castiel will forfeit his celestialness to become human.
Other than the rehashed "Swan Song" scene, I liked it. Solid episode.
