The present-day Hiro is hiding in the back with Samuel, who's watching everything with interest. Hiro is quizzing him on whether he's a time traveler, too, and if he's following him. Samuel says the question is what is Hiro doing here. He says he's here to save Charlie, and Samuel wonders why. Hiro reminds Samuel that he's the one who told him to right the wrongs of his life by stepping on the right butterflies. And Charlie? She's the biggest butterfly. She's Mothra! Except that I thought we determined the first time that this wasn't a wrong Hiro caused and that he couldn't stop it, no matter what? Otherwise, wouldn't he have gone back and done this before? Samuel says he's trying to protect Hiro, because this isn't a spilled slushy. This is something more, and everyone was on a particular path. He has him look at his past self so he gets it. He says Sylar, Peter, and Claire were all on their particular paths, too. Samuel tells him that one wrong move can change everything, and wonders if Charlie's actually worth that. Hiro says she is, and turns around to find her gone. Sylar's gone too.
