She does have a line or two if you go with the spanking option when you first meet her outside, but yeah, it is a bit lacking. Will probably add more later, thanks for bringing it up.
Hey i'm all for characters interactions. I loved the banter between the party members and non-party characters and all the talks and interactions they had in different spots of the map, pubs, inns, houses, quests and such.
The characters and the story are my favorite points in this game after all.
