A couple of years ago at Tony would have simply dismissed the man as insane, although that may still be the case in regards to mental state, he was more inclined to believe his story, or at least believe there were elements of truth to it. That didn't make it any easier to take, although Stark managed to keep his openly casual demeanor as they finished the handshake. He still had much to work on in letting people get to him, but not quite so fast as he was at aggravating others, there was at least that side to things.

"Few theories about time travel, not all my own. It time travel exists in the single dimensional sense, then you helping me to succeed is futile, because by doing so you would equally remove future you's motivation to travel back in time, thus trapping us all in a continual logic trap. What is more likely to have occurred, is you've hoped 'dimension.' I mean, we used to think that was impossible, but the science community has had a lot to thing about recently. If so, welcome to the best version of me, don't worry, we're on the case." Stark rattled off, like countless other times he bombarded those who stood against him, annoyed him or simply happened to be there, talking as much to himself a Bishop in front of him, although at the same time taking in his appearance. It was startling, although Tony could very much see the road the government was taking at this moment leading down to such an eventuality. On a road of bones, including his own.

"That said, we're about to wage war on the strongest and 'greatest' nation on Earth. I'm assuming you're not useless, due to the whole, being selected to come back and change the future, so, I'm not going to turn away good help where I can find it. I have some friends I'd like you to meet." Stark grinned slightly as he spoke, turning to leave, heading towards where both mission teams would be congregating to head out. There was an element of an unofficial goodbye to the whole thing, even for those they had only just met, at least it felt that way for Tony, but then, maybe he became a little dramatic when his life and the world were on the line.
