What a long, sad trip it's been

I really wanted Sam to reach out to Dean also, but now I'm thinking Sam was either too stunned to do anything or else he knew that sometimes, when someone is pouring their heart out like that, the best thing you can do is give them space. Just the way Dean is turned away from Sam the whole time he's talking I think he might have really flinched from any contact at that point, and Sam knows his brother well enough to understand that.

Either that or Sam's an idiot...
