|I think Sam was very much him, but not in the ussual way, more like Mystery Spot way, he said he remembers Hell but doesn't want to talk about it, he's very cold and completly shut down, he was cool to Dean but you can tell he's pretty much emotionless, which makes sense because while Dean falls appart at the burden of a bad memory or loss, Sam turns into a machine, OCD (which explains why he wants his own car, fixed his OWN way) and shuts down from feeling anything, his attitude just made sense to me, I'm interested in how is gonna play into the whole relationship when they have no choice but to start hunting together, if Sam will keep closing himself or something will make him explode, cuz lets face it, I know some people that do that, shut down, but something snaps, one way or another.|
I think Sam is still Sam too, and yes he is similar to Mystery Spot Sam but in Mystery Spot Sam was just masking his pain and feelings, as soon as he had the trickster in front of him he was begging for Dean back. He was very emotional. This Sam seems different in that he isn't masking the pain so much as simply not feeling it. Not just pain but all his other emotions are muted as well. He doesn't feel empathy and that is why I think he made that decision not to go to Dean. Because on an intellectual level it seemed like the right one but he didn't factor in Dean's pain at Sam being in hell because he cannot understand that right now.
