Fuck.
Dean's lying in bed, staring up at the ceiling. There's a pit in his stomach the size of the Grand Canyon -- okay, not physically possible, but it feels like there is. He's been awake for the past couple of hours; he can't fucking stop thinking.
He still can't believe Dad's dead. Of course, you'd think the way Sam won't shut up about it would help it sink into his brain, but instead it pretty much just makes him want to hit Sam. Which isn't fair, because it's not Sam's fault that Dad died.
It's not Sam's fault at all.
