Mary and Tony
That was a very nice and welcome change of topic, because Tony was trying to figure out how to explain the nuclear bomb and almost dying, and he didn't want to. His chest had started to constrict over it, in fact.
He took a deep breath, and then let it out. Science was good, and he lit up a bit as he spoke, "Hey, that's not a bad idea. I mean it's probably technically possible? Back there it required some fancy alien technology to build it all but over here the tech is so advanced, it probably requires less doing."
