Hmm. She might be one of two people - Remilia the Elder's apprentice or contemporary in witchcraft, or the girl Remi was briefly involved with way back. It'll be interesting to see where this goes. (Of course it's also possible I'm completely off the mark.)

I'm sincerely looking forward to the chaos that is about to ensue.

Edit: I'd lay my money on apprentice, judging by apparent age.
