at the switcheroo where Sam's rejecting family-oriented suburbia and Dean's longing for it.

I read this as Dean's seeing that Sam really did like the kid's life and Sam's denial as trying to deny to Dean and to himself that that's what he wanted.

What evidence was there that Sam really did like the kid's life, and when would Dean have seen it?

If anything, for me Sam was reminded of just how limiting that can feel -- people telling him what to do, in his business. Escaping that was one of the reasons he left for Stanford in the first place. And even more so now, the idea of anyone determining his destiny but him really has to irk.

I also thought it was interesting that Dean was the good role model, and Sam lied to the kid through his teeth.

I was mad at Dean for not asking Sam for their mother's maiden name the first second he thought something was up but I just now remembered that a shape changer would have known that.

Would one? How? Do shape changers get all the memories of the person they become? How does that work?

The shape changer from season 1 did. When Sam became suspicious he tested him on knowledge and he passed. He only worked it out properly because the interloper didn't have an injury Dean had just sustained. Then he got his ass whupped, so it didn't matter.

I let this go because I figured he initially thought something was wrong with Sam, not that it wasn't Sam. There's really plenty of room and plenty of precedent for something to be wrong with Sam. And I think there's also plenty of room for Dean to be unsure of his standing with Sam right now.

I just thought that Sam's "you have a great life" speech to the kid seemed a lot more impassioned than his denial that he wanted that kind of life. Sam was the one who tried for a normal life, after all.

Hmm. I bought his denial. I thought he was just trying to placate the kid. He seemed irritated by the restraints of family in general.

Don't make me watch it again. The cold opener almost killed me. I have a much lower tolerance for watching JP be goofy on Show than JA. I can't explain why.

Who am I kidding? Me and my FF button will be just fine.

Meanwhile, I enjoyed the teaser.

Also, did Dean have a silver knife on him when he confronted "Sam"? (Isn't that what you need to use on shifters?)
