You were just so distracted by how sexy Huppert is to answer. It's okay. It happens.
I was seeing something similar. Having her be a bit glacial and disapproving, but, definitely doing her part to keep the family name pristine. So, a lot of covering, not entirely disapproving, but... perhaps a word or two. Kind of a typical society lady; though she may care for Isidore (at least, more than he does for her >>;; ).
I think they could get on. :) I'll put a hold on her and we can iron out details?
