Though a regular person might not notice, Tony does lean somewhat back towards Loki, turning his shoulders to acknowledge his presence. Steve does notice, just like he notices almost everything, but he keeps his mouth shut. This part isn't his business. Does he trust Loki? No. He's been involved in helping resettle people, tending to the injured, but he is still grateful for the intel he'd brought. It makes Steve more accepting than tolerant.

"We're all right. Armor's shot," Tony says. He's already mostly pulled himself together and while his shirt is ripped, there's enough fabric to cover his chest and the reactor. "Got any of those sweet SHIELD hoodies in there?"

"Matter of fact, we do," Natasha calls from the ramp, tossing a white and black shirt in Tony's direction. It's much too big, and Steve frowns visibly enough for the assassin to smirk. "It's all right, handsome. We'll get you another. Can we give you boys a lift?"

Tony rolls up the arms of the sweatshirt and gestures for Steve to grab the armor. "Bring that with you? Great, thanks," he says, and moves with Loki towards the rescuing quinjet.
