He winced a little when she told him she got mistaken for someone else often, that couldn't be fun, he wouldn't have blamed her for being annoyed by it if she was. "Heh, yeah I know how that can be." Sort of, not really - it wasn't exactly the same but there was something about being a younger version of another you, people tended to look at you strangely. It wasn't something Tony was really used to. He was the only Tony Stark where he was from after all, not some other version of him.
"Oh yeah, no. He's definitely the other one." Tony was quick to assure her, sure most people didn't seem to think that, he was the odd one out most of the time - he felt that way even when Steve looked at him sometimes, which was kind of just.... ridiculous. "Old Tony, you know." He threw out there, just because he liked to make sure that distinction was stated, for his own benefit. He was Tony, that was Old Tony.
"You're new, right?" He asked, he thought maybe he'd seen her around a little, but he hadn't met her yet. Between his occasional mental breakdowns over Steve Rogers - both of them, thank you very much - and the work he was doing on the network to try and make things just a little more updated for the ease and convenience of them all, he realized he'd been a bit quiet since he arrived.
That was kind of new for him, Tony tended to be outgoing, he liked meeting people, liked making new friends, liked flirting and you know just being around people. This place, the people in it, they made him feel a little more reserved, like they looked at him and were always comparing him to the other version walking around and he just didn't measure up.
