Dean sighed heavily, getting to his feet and pushing a hand through his hair. "You stay here, I'll head out and get the beer." He was sure he'd need the peace and quiet in the car, the time alone, before he went and get dragged through everything they'd ever done to each other to make each other angry. He didn't know where they were starting but it wouldn't be pretty.
He doubted Sam would just take that plan, though, and simply pulled his keys from his pocket and headed for the door, grabbing his jacket from a chair as he did. This was going to be awful, he could feel it, that something was going to happen and it'd change them entirely.
So, yeah, beer was a damn good idea right now. It'd get him through tonight without him wanting to kill himself, or worse, kill Sam.
