The hesitation enticed a less practiced smile from Tony, scrunching his nose and making him forget about the tension long enough to give a breathy laugh. Training could have been all kinds of things when Pietro said it like that. Maybe that was just what Tony came here for; a little training. "Oh, don't trouble yourself on my account," he deterred, tossing his jacket onto the coat rack to lean with one hand planted against the wall next to Pietro's head, crowding him back to keep him still for Tony to curl two fingers under his chin through rough stubble.
"Just came to see if you wanted to have lunch or something," he mumbled, obviously not really committed to the words, quickly forgetting them to continue, "I like this. You beat the odds and manage to look pubescent." He smirked, dropping his hand but not moving away, clearly unconcerned with any offense Pietro might take.
