To avoid spoilers I'll keep the details minimum. At the end of the Balmora quest line you can talk to her and she'll start telling you something. Then she cuts off. You can persuade her, but again, she doesn't actually finish her story, she just says that one day she'll tell you something that'll "keep you on the edge of your seat".
So, do we ever find out what her story is? Like do we have to wait a certain amount of time and bump into her somewhere? Or is this, as of yet, a loose end?
