The jerk thing works on Tony, even if it also makes him ratchet up his own jerkiness. At least Steve's used to that by now, too. The elevator doors open and for a second he considers just walking away; not saying anything. But he was never good at that. Once provoked, he had to volley back the serve. "There are just certain things a guy should be able to count on," he replies evenly, if a little gruff. Then he stomps off and pushes himself right into Steve's bedroom. So maybe it has nothing to do with Cap sweating a little, but that was kind of obvious before.

Tony studies the room like an oil painting, making sure each piece is in its place. Nothing's changed, not really. Steve's made a home for himself here. There's even a small vitrola by the window, something that would have once made him sneer about nostalgia and foolishness, and now just brings a light smile to his lips. There's a laptop too, naturally, the painting of Peggy still hanging in the heart of the room. He swallows, turning to Steve as he (presumably) follows, looking prickly and vaguely apologetic.

"I'll keep you company while you shower, come on." He waves a hand towards the ensuite bathroom; because this is apparently still super important to him.
