Makes perfect sense to me! He wouldn't know about the Alchemy, of course.

Seems more than reasonable. He'll probably assume she has a power because of the previous events, but I'm thinking he'd have no idea what anybody has outside of ones he's been told (Stella) or seen (Zaylin). Specifics don't tend to register when your attention is occupied by not blasting everyone around you with lightning, and something as subtle as Flamel's Alchemy wouldn't even have been noticed in all of that.
