This sudden trend of calling him by his name when he was in the suit was almost enough for Tony to regret admitting his identity. There were boundaries and guards this suit was supposed to provide, and Tony was one of them. He had heard the approach, though hadn't expected it, not with Pietro looking so pathetic in front of him, and it made him stop and just turn his shoulders with a questioning, if impatient, tilt of his head. Hadn't it been quite clear that they were done talking? And Pietro had obviously been done long ago, what could he possibly want now?
He still looked pathetic, though. Enough to make Iron Man's stiff shoulders drop a fraction, Tony's focus somewhere behind Pietro. It would be easier if he just let him go.
