Hee, the early comment about rescuing a woman named Katie Holmes captured by some evil cult cracked me up :D.
I really love the Dean/Jo interaction. Definitely starting to OTP them. Dean really is opening up to her, saying he started so young he doesn't know anything else, but he wishes he did, and hopes that she won't start on the same path. And later on they share memories of their fathers and what started them on the hunting path.
I like it how she has that small smile on her face when Dean is complimenting her on the way she handled the business, even though her mother is mad at her now. Oh yeah, they really are starting to be an OTP.
Hmm, it seems there really was something more going on between Jo's mom and Daddy Winchester. But then it turns out there wasn't. She's mad at Daddy Winchester, because he's the one that got her husband killed on a hunt and now Jo's mad at the boys, too, even though none of it's their fault.
Hmm, all of this will probably bring some nice tension to the plot later on this season. Me like!
