My thoughts exactly. I'm more worried that so called teacher couldn't stop her..... I mean you are a teacher its your job to teach... Second issue there is no mention of informing duke of it but they went ahead and informed someone unrelated? Also there were no rumors abput her being cruel or anything why go straight to assume that she is dangerous... This does not make any sense... They could use the appearance of other duke with already existing conflict which was kinds trying to bully her - making retaliation for the humiliation they suffered and they meet in principals office with duke Rodwick being late by accident or something like this... So frustrated...
If she can't control her powers it's obviously you need to teach her your a teacher it's your job you can't expect a new student to already know how to control it and just because she came from a powerful family you'll prevent her to learn? How stupid is that
