"Ancient Egypt?" He asked more surprised by that answer than maybe any other he could have gotten, "No way, that's amazing." There were so many points in human history where things could have gone differently, where a mutation could have cropped up and changed the course of everything. But even still he wouldn't have guessed that. And he had just a brief moment of hilarity where he wondered if there were Ancient Aliens shows where Jean was from that suggested that's where mutants came from. As plainly ridiculous as all the other theories that put out there into the world where he was from, in a world that was dead set on not understanding that people had been clever long before they'd invented things like computers, or that people who weren't as lily white as he was could actually come up with brilliant solutions for things that modern people might not.
He hadn't thought of it the way she mentioned that it was an evolution about survival. His initial thought had been a mutation because of the added radiation that the world had been exposed to in that time, random at best, but she was right - it'd have to be based on survival. Mutations rarely were things that happened for no reason. "Right around then though, I can just imagine how well that went over in a time when people were looking to lay the blame for everything that was going wrong on anyone but themselves."
Tony didn't know what kind of world Jean lived in, what people thought about mutants, but if he had to take an educated guess based on the way she'd corrected him, he had to imagine it was one that was lukewarm about mutants at best, and something a great deal less than that more likely.
But then she displayed just a little of her abilities, fingers to her temple Tony half expected to feel her in his mind, but instead the water began to rise up out of the fountain. "Okay, that-" He said nodding to the globes of water as they floated up over the fountain, "is amazing. But you're not all able to do things like this right?" He asked, "Everyone has different abilities?"
