This is one of the reasons on why I'm against with Arthur showing way too much favor on one of the people he interacts with, especially in school, and now look at what they plan on doing, they even think of using Tessia against him because Arthur showed that she can be a liability to him.... tsk tsk
He already has a family to protect and worry about and he's even making that much more difficult by giving his enemies possible liability they think they can use against him just like now
