"Not your fault," Dean manages, and he's been sitting up too long. His ribs are starting to needle at him, so he sets down the hot chocolate and lays back, groaning under his breath. He closes his eyes for a long moment, and then finally replies.

"You're not around, where I come from. Haven't been for a long time. Dad-- all he had on his mind was revenge. The thing that... killed you, that's what he was hunting. He brought me n' Sam with him, he had no other choice." Dean pauses, and this feels familiar. But he shakes that deja vu off, annoyed with it. "Sam went to college. Had a girlfriend. I stayed with Dad, hunting things, saving people."

And that's about as vague as he can make it.
