hmmm, at first when I watched this I was freakin' out because it really seemed like Sam was not able to control things and blanking out. But now I think when he was talking to Dean about not remembering things that was all just the Demon talking, leading Dean on right? (Is that too obvious?). Anyways, if I remember correctly, Didn't real!Meg remember things after the Demon left her body? So shouldn't Sam remember all the things he did too? I totally fell for the Sam goes evil hook line and sinker just like we were supposed to. And Dean, poor Dean, is in such denial about things and he is trying so hard to keep him safe!!! *wibbles*
