Karstedt yes, but I have the feeling that despite him wanting to help and protect Rozemyne, Bonifatius with his near complete lack of tact would end up blunding in some way, that makes things worse for her.

Speaking with Hannelore is probably the best course of action, since they truly are in the same situation (young girls, thrust into battle and expected to not show their discomfort due to their position in noble society, ect). And it comes with the added bonus of allowing Hannelore a similar release, which she surely can’t get until she gets back home and can talk with her mother in private. Though for Hannelore the situation might well be even worse, since Rozemyne is already known to be eccentric by noble standards and with how obsessed Dunkelfergerians are with strength and resilience, showing this kind of weakness might carry even more stigma in their duchy… or maybe I’m wrong and them being such fight fanatics has given them better understanding of PTSD and how to deal with it…
