Nathan actually hoped that was true, but he didn't know if he would ever find out if she was right in all cases, or just for herself.
However, her explanation made memory flare and he grinned widely. "And you taught him to speak better English!" And other things, but Nathan wasn't exactly going to say Hiro had said that, especially not when the only Hiro to learn Nathan had said so might happily beat him up. "He mentioned you. Back in my time, that is. I doubt he mentioned me, but I guess you could say I'm Nathan Petrelli, a.k.a.," he made the gesture, albeit small and still a little embarrassed even now, "Flying Man."
It was actually the wildly enthusiastic shout plus arm gesture that was embarrassing, rather than the title.
