"I've heard a bit about Dr Maruki, since coming here..." she says. "It's a little hard to believe it all, to be honest. I've only met him once, but he seemed so normal, you know?"

She nods to herself at what Goro says about his own timeline. "Sounds like you're making changes, though!" She says. "The bigger changes always come from the smaller ones, too."
