Of course Tony followed, making gestures to the stunned ladies of apology and promise to return that he didn't intend to honour in the least. Jess was here, and she was feisty. And without Bruce to shoulder the heavy honour, Tony didn't have a tactic to gracefully extract himself from a blisteringly hot threesome. A man wasn't supposed to turn that down, it wasn't in Tony's blood or bones. He could already feel his dad's disappointment from the grave, but then maybe that was a reliable constant.
"I think I overplayed it with the swimsuit thing," he reflected soberly. "My bad, caught up in the moment, lesson learned." With a hand clapped to Bruce's back (only partly in the case he needed to sacrifice Bruce to Jess' ill will to buy himself enough time to make a getaway) he admired, "You handled that well, though, Jessie. Oscar worthy, if I may say so." She didn't completely lose her smile, and wasn't holding anything she could easily stab with that Tony could see (that dress was wonderfully reassuring), so, cautiously sticking to Bruce's side, he made a careful move to invite her into a friendly kiss.
