Reminding Bruce of the possibility that he could Hulk out during sex is not really a good way to frame the conversation, no. He gets pulled out of the moment there when Tony brings that up, not that he'd really been excited to be in the moment leading up to that. Tony talking to the Hulk about the two of them doesn't even make sense to Bruce. Who cares what he thinks? If he thinks at all, if he...

There's a lot of hatred there, and Bruce is only starting to realize that that might be unhealthy, largely thanks to Tony. He tries to shake off where he'd tensed up, and he pulls Tony closer, making sure he stays here, making sure he doesn't leave Bruce alone with this. Because Bruce does pull away, draw into himself, does prefer to handle things on his own. He'd done it out of necessity, and he's still not entirely convinced that it's not the best way to go about handling his... life, but he'll try, for Tony.

"I don't even know how to... I don't think there's anyone else in the world who would've thought of that, Tony."
