I would have liked for Yubel to have possessed Blair, picture if you will, Jaden/Judia waking up in the middle of the night bound by a horny Yubel possessed Blair, both of their desire for him being amplified by they're lust, with a yandere type look on their face as they straddle his hips with the goal of mating in mind!
You have to admit, that is pretty tantalizing!
