For Tony, it hasn't been so long at all -- four months, only. Nearly a full one on the Benatar with Nebula and then about three here. The wound was still fresh, and Tony forever moved in ways that broke his stitches wide open again. But this news was -- a salve, at least. Somewhere, no matter what he was doing here, the universe was back to the right order. Peter would be back, and Tony would still have his daughter. Tony wasn't fool enough to not realize that meant there weren't still people that would have died and that would be sorely missed.
"Time travel." There was nearly an eye roll in his comment because he'd called that. Time travel, it always found a way to come back and bite, and he'd known that, even without ever having done it. The odds were stacked, the math was there. But in this particular instance, for Nebula, it was good. So that mattered. "You'll find her." He knew some about Gamora now, of course - one couldn't spend an entire month on a ship with only one person without sharing information. He knew Nebula loved her sister above all things. "Do--" he paused, uncertain. "Paramater is that way?"
He doubted, very much, that he would be so lucky. And if he was, he doubted that he would feel lucky. He couldn't leave, not without the rest.
