I think the Duke needs to tell Fleta he is her uncle. That would've probably got FLETA to want to go with him more than having to stay with her sister. I mean the whole story would change if she isn't there to raise Fleta which is probably why they didn't write the story this way. Still Felt haas a right to know she has other family.
Doesn’t matter, family means nothing to Fleta. She would feel the same way about a random maid as she does with fl if they had treated her kindly instead of fl.
