First off, I am crying that we have to wait until the end of January for a new episode. That stinks big time!
This episode was awesome! Way to keep me on the edge of my seat for the entire time. I loved the whole thing.
I'm so glad Sam's soul is back, because really, there was no where else to go after this episode. What was he supposed to do, hug Bobby and apologize for wanting to kill him? That was never going to go away and it was never going to be okay. Sam would have eventually killed him to ensure his soul wasn't returned. And then there's the irreparably broken relationship with Dean. You can't fix that. No matter what. Sam without a soul was a monster and was becoming more of one every episode. I will admit that I loved his hardness and his persona, but I'm ready to have emo Sam back.
I loved the characterization of Death. I loved that Dean talked to him with his sarcasm, despite Death's ability to kill him on the spot. I loved that Death wanted Dean to learn how they screw with the order of things. And I loved that despite how much Dean wanted Sam's soul back, he did the right thing in saving the husband of the dead nurse.
So, Thank You, Supernatural People, for another great episode.
