Where does livrea talk about having met the pirate Maidensbane, so to unlock the latters talk options when asking if have heard about her?

[Papum]

As the title suggests.

 

[Tarnakus]

It is during the time you meet her in Hawkethorne - I think on old save (or you pass it already) the only option is to save edit.
Then Flirt and ask her story.
