Not a degree that Tony liked. That math wasn't adding up and Bucky didn't seem like the sort of man who'd let himself be controlled by someone else, not after all he'd gone through, but Zemo was clever enough to pull off plots that were intricate enough to sound almost stupid when explained out loud so.... there was that.
Tony was quiet for a moment, the HUD taking care of all the vantage points around and maybe Steve didn't see anything but he didn't have the tech Tony did. "Maybe not," he decided after a moment. "He doesn't have the resources, even though I'm sure he wished he did. It was just a thought." But probably it was just the hotel fucking with them all again. Zemo had no more control over it than anyone else in the hotel did, of that Tony was certain.
"Listen, Cap, I'm all about some fisticuffs if you want, but there doesn't seem to be much point in it."
