[He laughs, actually laughs at Dean's little lecture. And it isn't to be an asshole, it isn't just meant to piss the guy off. Seriously, it's not. It's amusement bubbling to the surface. Something bitter and broken but still amused riding high inside him.]

Yeah, because my liver is really something I worry about. [He rolls his head to the side, slightly, eyeing Dean with that same tired, bitter sense of amusement etched onto his face, lines normally hidden well enough all too visible right now. Making him actually look as old as he is.] Ever think that maybe I'm just a genius enough who's figured out how to beat biological setbacks like that?

[He turns away again, then, just focusing in on the other side of the cell he's in, narrowing his eyes at it, instead of having to deal with whatever look Dean's giving him.]

Wasn't my idea to be locked down here. Could have done this just as easily in my room. But sure, kick my ass. [He smirks, eyes sliding closed again] Wouldn't be the first person to want to because of what I do drunk.

[Wouldn't be the first person to try while he is drunk, even. No, Rhodey takes the cake for worst drunken bitch fight.

And even given that, Tony still goes for the bottle. He knows exactly what that says about him.]
