"So it is business," Tony acknowledged in a mumble with defeated acquiescence. His smirk couldn't be kept at bay for long, though, and he was quick to launch himself from his seat to graciously take her hand again, happy to play the gentleman. At least she wasn't going to try to lead. She didn't have to know she was looking in all the wrong places for heroes-- or maybe she already did and she wasn't going to get the satisfaction of a reaction for her dig. The Iron Man's recent behaviour wasn't exactly favourable to the rest of the world, except maybe Al Qaeda.
With a hand already at the small of her back, appreciating the fabric of her gown, he lead them away from the chairs and table where he helpfully deposited her champagne for her, through the crowd to a welcome patch of floor. It was maybe not quite space enough for any dramatics, but Tony seemed happy to squeeze close to her with a helpless smile. "I'll try not to seem too bored if you want to tell me what you do when you're not stalking me," he promised, bent to speak down to her neck. Whether she went on flirting or told him what exactly she meant to do with her hero collection, Tony didn't mind. He would prefer the former, though.
