I think there is an enormous amount of guilt that Dean carries around with him, for many things. Like I was saying earlier…I think that’s just part of who he is, it’s part of what keeps him running. There’s that weight to bear and he bears it. It’s his cross to bear. The guilt of losing his father, the guilt of losing Bobby, the guilt of not being able to protect his brother at all times. The guilt of not knowing whether brother is going to make it, the guilt of doing what he did in Hell. When all those things add up… it’s… you know, life is pretty grim for Dean. But he’s still able to smile and turn on the radio and eat cheeseburgers. You know, he’s just got that vulnerability about him and he has that strength about him.
