[ Well, there's...absolutely no recognition on Naegi's face, though as he takes a step backwards (...and then another, so he doesn't have to crane his head up and isn't in a personal space bubble) he does blink in surprise and take a closer look. Since the guy said his name. But...

Nope. He doesn't look the least bit familiar. Naegi can at least imagine one reason he might not recognize someone who knows him, though. But maybe if he just...takes another moment to stare to be sure? ]

No, er, I'm fine. I was distracted... [ Staring is creepy, let's actually nix that plan. There's an almost automatic, awkward smile, before...more apologies. ] ...I'm sorry, I imagine we've met before [ Since that had been his name ] but I don't remember it.

[ Of course, that means he could have met Mr. Mysterious anytime in the past two years. ]

I, er, I've forgotten a fair amount of things, but if you don't mind reminding me of your name, I promise I won't forget it this time...? [ Unless someone mindwipes him, in which case he can't make any promises, but surely that's not a common problem...

...If this guy met him back in that time, this is confusing and interesting for a number of reasons but he. Shouldn't jump straight to questions, should he? At least introductions are pretty important, even if they're one-sided. ]
