The brothers weren't together too much this episode, but I quite enjoyed it. I knew that the kid wouldn't be Dean's, but be a vehicle for him to consider where his life has been and where its going. He knows he doesn't have much longer to live. I thought it worked great as a follow-up to the premiere. Dean is trying to hide what is really going on inside. This episode we started to see that facade break.
I can't say I'm surprised. I'm in the minority that wasn't bothered by last week's Dean or the episode itself so this week seemed like a natural extension.
As for Sam, he is also doing what I expected he would do - keep on finding a way to help Dean. Also, I like that they are bringing the mom thing back into play which they started to set up last season. I just hope they don't mess it up and make it stupid.
The kids were creepy and the women playing the mothers did a bang up job.
meg_tdj looks like you were right - the girl's a demon and she has a way of saving Dean. I'm not sure how they are going to play this up, but I hope it's done well. This tpype of storyline can go south fast, but it has a lot of potential.
Anyway, I thought it was a good episode. Next week's? Eh. We'll see.
