did all her rebellion quests sucessfully, all her comrades survived etc, iirc her affection and happiness were abysmal and i dunno why, treated her nicely, walks, dates etc and her willpower was around 80 above or below i cant remember. the reason i freed her was because i got tired of trying to make her happy when her affection and happiness just kept falling but once i released her, i couldnt talk to her once the rebel forces were strong enough, no mail, no icons, nothing just poof
i was also doing a gangas khan playthtough, i didnt really have slaves outside of story ones, the rest of the house was my kids and some mercs
