Just one crutch to another, different names, still a god damned poison. But what's it to me, how you fuck up? I'm just your fucking janitor, aren't I, kid? Picking up the pieces." He gave what amounted to a defeated shrug and turned to leave the room. Lectures didn't work, killing four thousand people didn't work, so Nick really wasn't sure what was going to get through to him. And anyway, he had Tony's mess to go and clean up.
