I've seen it cited as being a proof positive that Sam hasn't changed since pre-Season 1 and that his current behaviour is simply another demonstration a long-standing behavioural traits.
But...
But...but...that doesn't make sense at all! Okay. Sam left his family, left the family business, to go to Stanford. No argument. In season one he almost left again (Scarecrow) and in season two he did leave (Hunted). If Sam hasn't changed, why hasn't he left Dean already? The guy is being an ass: I would have left him four episodes back. In spite of everything, Sam is still with Dean. Oh, sure, he's taking the odd time-out with Ruby, but he comes right back every damn time. That is not a long-standing trait: that's new.
