I don't remember much, but if I'm not wrong, Finne's mother married Liselotte's father's brothers. So that'd make Finne a noble. Thus, Bart can marry her without having to give up his sword or something. Liselotte won't interfere much, but she'll kinda set them up, making their relationship progress faster.

It would be funny if Finnes mom and Lises dad were related
