Tony almost made a sound of disappointment as Steve's hand fell away, but then he was unbuttoning his shirt, and that was much more interesting. Except right there in the center of his chest was an unmistakably familiar shape, and Tony's eyes went wide.

"I. Yeah," he said, sounding just a little dazed, and reached up to undo his own shirt. Light spilled out before he'd gotten them all the way undone, and then there was the reactor, all metal and glass and set in the middle of Tony's chest. Tony barely even remembered to worry about the scattered scars surrounding it.

"I've always known," he admitted quietly, and blindly reached to strip off his watch to show the shield design marked into the skin inside of his wrist. Oddly that, more than his half-open shirt even, made him feel exposed. He'd been keeping that mark covered since he'd been a teenager, after all.
