Reverse petplay has been in for a good long while now. So has the Ops Deck, but IDK if any of William's scenes made it in there.
Named, recruitable Jumper NPC Will planned and has a lot of artwork of. I guess she wasn't fully finished before he left.
Her first husband and her sons died in a bombing attack on a military parade the whole family was in; she and her daughter were a few ships behind the target, so they were unscathed. She eventually got a second husband, but he kidnapped, drugged and bimbofied her daughter and sent her messages/pictures taunting her with the results (which is why she's not comfortable with Bimbo/Brute Steeles) before they both died in a UGC raid. When she realises she's falling in love with Steele, her trauma over her past marriages causes her to avoid them out of fear of something terrible happening again, and even implied attempt suicide (given that she has bandaged cuts on her wrist during the confrontation) - Steele must confront her in the wilderness, during which she reveals how her previous marriages went down. The whole series culminates in her throwing away her second husband's ring, accepting her love for Steele, and gaining a third tail for them (who can now succeed at the Touch Fluffy Tail option). I'm pretty sure all that is in the publicly-accessible document repository linked in this thread's initial post, if you want more details.
