Awesome post! I really have nothing to add. Emotions were running high from all characters this episode, and it was wonderfully done. I would like to see some sort of reconciliation scene between Dean and Cas. Not for a shippy reason, but just because they didn't part on the best of terms. And I'm also very interested in why Dean could look at (and hey, kill) Zachariah. (Because I think it's sort of lame that humans can kill angels, if they just have the right sword. I very much liked the spin that only angels can kill other angels. Even Alistair and Lilith didn't know how to kill angels.)
