Mark's eyes widened with surprise at Roger's admission. A cure. An actual cure? Oh, sure, it's what they'd all hoped for. And they were several years in the future, all the smartest people in the world working on it for so long had to come to some good. But an actual cure? He couldn't entirely grasp it. "But why just him?" he began, his voice both worried and eager at the same time. "Why couldn't it be you? Or everyone? What did he do differently?"
Any time he could get extra was enough to give him hope. Mark only desperately wished that Collins and Mimi were there, too, if that's what it got them. And Angel. If Maureen was there from before his and Roger's time, why couldn't Angel be? Was that even possible? Could they go back and change time?
Well. No. Probably not, not if they were actually fictional. But it could get them some more time. And if they really were there to prevent the end of the world, did it even matter? "Hey," he asked suddenly, not even knowing if Roger would have the answer. "What happens back home? I mean, I'm pretty sure we would have noticed Maureen being gone for months at a time, don't you think?"
