"I know, but that's not going to stop me. And you're welcome." This guy's probably been working his ass off making sure the rest of his teammates get back to the train safely (something Wash isn't able to do without risking a massive backslide on his part); leaving him to his own devices after all that is a dick move at best.

(Plus, sleeping in the rain? Does he want hypothermia? Because that's how you get hypothermia.)

"You know, I haven't seen it happen, but if I do I'll let you know." He's been yanked back to his own bunk, at least - evidently the train isn't about to let him or anyone else stay up all night, and the train seems to have final say on that one. It hasn't happened in the middle of the day, though - not to him, at least. "Also, what's your name?"
