Hey, thanks for posting those songs!! I liked the music from this episode. But uh, yeah, I didn't see the episode before this, but the atmosphere made sense to me. Just because that's the way that Dean is, really light and nonchalant about the fact that he's basically fucked. And of course Sam is unhappy about what sorts of positions Dean is being put in. But Dean doesn't care. I mean, he probably knows it, and the atmosphere IS strained because he probably knows Sam is unhappy and trying to make it lighter, but obviously failing. I would be pissed off if I were Sam too.
