Wrong Tony
After crashing unceremoniously in the X-Mansion's front garden, Tony had taken up the offer to stay a few nights and help with the whole dimension mix-up. It was strange, being stranded here without his giant piles of work and money. Of course, he could easily drum up some business if he had to, hell, if this took longer - there didn't seem to be an equivalent of him in this universe, and he'd crashed and burned so often starting from scratch wouldn't be impossible.
For now, though, he was here, still wearing X-Men Institute's exercise garb, and trying to work out a more short-time technical solution. He was just wandering through the building looking for Hank since he had another idea to put into action when he noticed two men at the end of the corridor. Though he was dressed like a kid's show ninja on his off day (still a very attractive ninja), he recognized Steve in a heartbeat, and just seeing his best friend brightened Tony's mood considerably. Next to Steve stood a sourly-looking blond he'd seen around before, playing with the machines in a way that looked quite professional, even if Tony doubted all that swearing was strictly necessary for the well-being of the appliances.
"New costume, Cap?"
The chances that this was his Captain America were narrow, but Tony was so used to being friends with Steve, the idea that they weren't in any universe didn't half occur to him until a second later. Still, he approached. At least he could say sorry for being to chummy with a military official (or whatever this Steve was) if Steve didn't recognize him.
