The others are out. Dean knows without looking and he's right behind them, backing up slowly while keeping the remaining scumbags covered. Except for how his feet won't seem to move. He should go. He needs to go. Right the fuck now. But he's got this. He's got it. He's good.
When rapist guy slugs him he's not surprised. It's like he was waiting for it. But he's got this. He does. There's a cliff behind him so steep it's almost insurmountable, but he's hauled himself up it before. There's a precipice in front and he's gone over that a time or two also. But he's solid on the edge now and he warns them. Warns them. Stepbackstepbackstepback. If rapist guy disengages, he can disengage too. He can. The Mark isn't pushing him, he told Sam that. He's camped out here, one step from free fall, Alastair whispering in one ear and Crowley in the other, but he's good. Because they're not here now. It's just him and he's got this.

He doesn't mean it, but the hilt finds his hand and all he knows is the dance of blade and bone and blood and he's good. He's got this.
