I kinda hope she hurts someone. Will goes to show that they're unable to fulfill that condition.
And yeah, "Let's not tell her about anything, so accidents happen out of ignorance".
I guess that dragons can take human form (or I don't want to imagine what her mother did), so they should have just asked a dragon (or even, you know, HER FATHER) to give some guidance and teach her about what to expect, instead of that half-assed "secret operative" teacher. It's like every time the guy is like "Oh yeah, there was that.. totally forgot about it, teehee". Not to mention the mother, which seems to be as irresponsible.
