My understanding is that she definitely loves Arvel, but this time she already have the capacity of realising that the marriage is important for the family, and now is confronting him one last time to maybe tie any loose ends.So.... Seraphina likes the two brothers, but she can't decide who to love because she liked both of them... And now she's going to consult with Arvel? Hmmmm... And how come he's grounded if the scums are trying to rape a person? Power play of the opposing nobilities?
Or maybe run together. That might also be lovely.
