If Nathan could go back in time and erase someone's birth it'd have to be yours. Or you know, Mister Sinister's so he wouldn't completely mess up every single aspect of Nathan's life and create a really complicated love triangle between his mother(s?) and his father. But mostly yours. You were...persistent. He'd admit that, you never failed to say something that would have him grinding his teeth. And you were always so familiar it drove him bonkers. When you called him 'Natty' while trying to catch his attention he could practically feel the aneurysm coming. "Call me that again and I'll go back in time and make sure your great grandparents were never even born" Nathan growled, clearly unamused by your incessant pestering.
