I'm currently in Mistwatch and am contemplating whether to help Fjona or kill and loot her. The thing is if I help her, she promises to repay me someday. Does she ever do so? I've looked online and I can't find anything about how she might repay me. DLC?

I killed her after taking her wedding ring because she's a bandit and a kidnapper. Unfortunately, it remained open forever.
