Closest to my guess is C. Rather than "won't be able to", it's more like "She can try."
That head-patting session was great. These two really suit each other.
I was worried about the princess, but it sounds like she'll be more ally than enemy here. Probably has some vicious and all around nasty scoldings in her, but for the most part, my expectation is a semi-tsun good person.
Oooh. Unless she likes Jullius and the invitation was to vet/harass his new lover. That'd be a curveball, but not one that we can't get a friendship out of.
@WhimsiCat You'd think so, but I don't think mom should've been able to do the half the things she did openly. It's pretty ridiculous that they even got this far.
