I'm... Assuming she showed up because of the wizard being controlled? Something about hearing the first and last sentences. I wonder if this is the start of an all-out war, I thought it would focus on the vampires but maybe they'll be skimming the outskirts of a wizard-church war. I guess since her dad was also a wizard..? I dunno.
I suppose she taught snake-eyes so maybe she'd show up just to save his life, but I also dunno.
Also am I misinterpreting but 'the first three sentences' meaning what, the first you ever uttered as a toddler? Those seem rather meaningless.
