Tony looks up when he hears someone swear loudly, just in time to see some guy with a mullet fall on his ass. What the hell?

"Whoa. Hey, man." Tony stands up and takes a step forward, holding out his hand to help the guy up. "Are you okay?"

It doesn't immediately occur to Tony that he might be reacting to the armor: he's too used to his identity being public, here, and being able to use the armor whenever he wants. It's such a part of him, he sometimes almost forgets he's wearing it.
