if you side with hekima, he asks you if it's ok for him to pursue anya. and then ntr starts (if you set ntr to on that is).
honestly, Anya is clearly "happier" to be in a relationship with you if you choose the against option rather than the ally option. regardless of hekima's intent (which is sus to begin), the asshole did traumatize them and also murdered old ladies. I spared him because I figure he'll be of use later (and if not, I can just rationalize that van's people killed him off later).
both van and eric can suck it.
