Tony zones back in from his mental tinkering when Matt finishes to keep himself from speaking through JARVIS (the Avengers might be used to the occasional Voice of Legion routine, but he doesn't want to startle him with it). "And we've got you something put together. I'll hide over here" - and mask himself with more holograms - "but if I'm distracting, let me know."

He pauses a beat. "And I'm going to start it up," he warns him - and then the room changes, Tony himself, by all appearances, disappearing as Matt finds himself standing on a rooftop overlooking a city. JARVIS has fixed the shoe issue, too, and given him the cowl - and in a few moments, when he judges that Matt's adjusted to the change in scenery, there will be the sound of breaking glass, and a scream. There's not a lot of actual story, here - he's mostly trying to give Matt a direction.
