"Jesus, Mary 'n Joseph. The hell's the matter with you?" Jayne keeps a safe distance in between them as he asks, completely creeped out. What is he supposed to do in this situation? Kaylee's no where to be found, and he doesn't even know if River's got herself some friends here that he could contact. Even if he did know of anyone, his tablet's all the way down in his bunk and if he leaves her alone to go fetch it, he'll come back to her smearing her blood all over the walls or something, and he'll be the one who'll have to clean it all up.

"Just... take a gorram breath, girl." he tries, not really expecting her to listen. "Now, what is it? Yer hands are dirty? You can just go in the bathroom and wash 'em. All right? No call for raisin' a fuss."
