Loki / Tony
Tony had been stopped several times about the armor, mostly so people could get pictures and well... who was Tony to say no? You know? When people were so impressed by his work, by his costume, okay maybe he was enjoying himself, despite the strangeness of all of this, of this not being the sort of place that he expected when he'd opened the door Tony was utterly delighted by it all.
And then he got another compliment, and Tony grinned, "Thanks, I made it." He admitted, because well - why not? He had, and he just because he wasn't dressed up like someone else didn't mean he couldn't show off a little. And then he noticed who had complimented him and tilted his head.
"Loki?" He asked, he looked like the Loki they'd left at the Academy, and yet not - maybe he was just dressed up like him? But the costume was a little off, not quite right if that's what it was. He looked like he was the right age, or near enough, but there was just enough that wasn't right to make him think this wasn't the Loki that he knew at the Academy. It was too bad really.
"I like your costume too." He said finally, "A different take on the look I'm more familiar with."
