Miss Gallahan realized that the fight had something to do about their own family's personal issue and decided to stop questioning. She couldn't exactly apprehend the Lord for such a fight as it doesn't broke any laws or rule in the Church. However she found something odd and couldn't herself to think about how odd it is for Estelle to go against her father's words as she seemed to be a very obedient person and daughter.
Perhaps because she love the lord too deeply? It's not new for many young ladies of noble house to discard their title because they love someone else their parents do not agree which often ends up in the girl going back home and hardly ever becoming a successful family.
