"Get out of my fucking sight," he spits, because the adrenaline is turning into more emptiness, and the anger is sucking out of him like a vacuum, and he's a little worried that he won't be able to stand without those two things. And, yeah, he really does not want to collapse in front of Cas. So Cas running works out fine. Running to nothing, just like Dean wants him to. He'll sleep in the cold outside, miserable, and Dean should feel good about this but everything just feels like tiny pins stabbed into his chest.

The motel room door is only a few steps behind him but it's suddenly a million miles away. Sam is going to ask questions - what happened to you, where's the beer, back so soon - and Dean has to prepare himself for that, too. He can't have one fucking ex-friend. No, he has to have the nosy brother too, to make it all goddamn worse. "Don't come back here," he hisses, finally finding the doorknob, thank fucking god.
