Tony is not used to people just wandering into his workspace. He could close the door, probably, but it hasn't occurred to him here. At least not while he's still getting the place set up and carting things in and out all the time.

All of which explains why he jumps nearly a foot in the air as an unexpected voice suddenly comes out of nowhere. He twists abruptly, eyes wide, to find a guy just...sitting there. Huh.

"Uh, hi?" He says, looking a bit baffled by the whole situation. "Can I help you?"
