It makes me VERY happy that you thought I got the banter right! I've only just started writing these two and I find them tricky. (The hotness, though, I don't think I can claim credit for - Sam just brings that himself. *g*)

Haha, I had not planned on a sequel because I didn't really want to deal with the aftermath (and neither did Dean!) but uh, then I had an idea about that, so... we'll see, I guess. :)
