It's good to have you back, Sam. I've missed you.
Dean, you've always been crap at lying and keeping secrets, why do you even try?
Oh, Bobby.
Oh, Cas! With the non-hug! Yes, dear, that would have been awkward. But good therapy for both of you.
I loved Dean's reaction to finding out Cas tipped Sam off. "Cas. Like a child." Well, as long as it doesn't concern his agenda, Cas is absolutely crap at lying. You should have figured that out by now, Dean, dear.
The sword-scenes. Oh, heavens, I haven't sniggered that much in a long while.
Dean's a magpie! That amused me quite a bit as well.
Interesting new villain. Also quite interesting that once again, the villain is female. Which is either cool or a pretty clear statement on the old Eve-complex. I shall go with the "the female of the species is more deadly than the male" twist and wait for what they do with it before condeming it as sexist.
I also sure want to know about Bobby's story with the lovely and snarky professor with the seriously cool house.
