Tony had no idea what to expect, honestly. A talking raccoon and a man who looks to be made of stone tattooed from head to toe was not even a consideration that had entered his mind. Peter's worry about theft is even more amusing on top of all the rest, but he knows he needs to not laugh right now despite his very real urge to do just that. He doesn't even bother looking around, there's nothing they could take in this room he couldn't replace. And he'd already offered his facility and everything he had to them. It's endearing honestly, even if he can't help but flashback on his own psych eval for the Avengers in the early days. Giving these guys the (bemused) benefit of the doubt seems key, especially when Gamora describes what they can do.

"I'm Tony," he says with a casual wave, then points to Steve. "That's Cap. I'm an engineer and he's a soldier so I think we'll get along fine." He nods, even more curious now about who else they're hiding away, but this seems an auspicious enough start. It doesn't take long for he and Rocket to spiral into a side conversation about micro-explosions because of course it doesn't. Xoxo besties already.
