The moment Nick started with the shouting, Tony frowned at him, lip starting to curl at the hysteria. This really wasn't a space that supported hysterics. "Seriously?" he had to press to Nick's question, still not looking impressed, but he relaxed back onto his hands and wasn't watching Billy like he thought he might collapse at any second. The S.H.I.E.L.D. monkeys might actually be making some headway.
"I'm due. Tell me when you get a couple days off, boss, it's like a spiritual cleanser. Just try to imagine the kind of person I'd be if I wasn't regularly humbled by the might of Everest," Tony offered, finally smirking again at Nick. "Healed up yet?" he managed to ask then, a much easier to articulate concern than the one he had for Billy.
