To be honest, I've never found Sam all that lovey-dovey about anything. The show has often maintained that Dean is the hard-boiled one while Sam is the tenderhearted softie but I think for so many viewers it's exactly the opposite. Sam had a few moments in the first three seasons where he seemed to have real affection for his brother but he always had a hardened streak of self-interest that was wholly absent from Dean. Since Season 4 -- so for nearly three years -- that side of Sam is the one we've seen more than any other. So I just can't imagine where Jared is getting this bizarre notion that Sam suddenly isn't going to be lovey-dovey anymore because of the 20 minutes he spent in "the worst part of hell." I'm sure he's getting this shit from the writers, which perfectly illustrates what I said a while back about reading interviews that make you go wtf? It astounds me that this is really how they see Sam...and it goes a long way to explaining why they haven't done anything to salvage his character. They don't even realize that he needs salvation.
