A). Lol, been there, done that.
Seems like they spent quite a bit of time together. They're still young, theres no way he can't recognize her just because her hair has grown out and she lost some baby weight. I know ppl have major glow-ups, but if he's such an elite, he'd put two and two together by now.... especially when he hears her name. But I'm sure he already recognized her from when she tried to read his wet papers. Some funny things can happen with them both pretending not to know each other.
