This is a beautiful and emotional review. <3 As for me, I still can't seem to find my emotions... Except I fear for Cas more than I did the whole summer, and I'm still pretty annoyed with Dean. I'm also intrigued with the new Big Bad, but I want him out of Cas ASAP! T_T Go possess smn else, dude!
I admire your faith in Balthazar, but I honestly can't imagine him being there. Even if he had been before, he would have probably not been able to hold on when they released the other souls... Or the Leviathan gobbled him up.
