She steamrolled through that one and locked it in, so Tony could only give her a knowing, disapproving point for dirty tricks. They both knew better than that, really; he wasn't the only one there when she was splayed out and gloriously exhausted on more than one occasion, and he could only coherently remember half of their relationship. If she was trying to get him to prove his stamina...it was only kind of working.
It was probably good for him that she went and mellowed it out then, but Tony did grimace at the reminder that this wasn't a casual conversation as if that glass separating them hadn't been imposing enough. He turned to take a long, contemplative drag of his cigarette before breathing a smokey, "Maybe," with a sidelong look her way. A little flirting didn't purge her record, the fact that she actually shot him, or the likeliness that her next move would be killing the Avengers. That was a startling reminder in itself, and Tony flexed his hand, belatedly crossing his chest to tuck it under his arm. "You keep coming back anyway," he pointed out.
