Not Sure, I think Indivi, made it so that you can Save Cassie, without Fawn?
You can try and Hire Arlene, or you are trying to Talk to Fawn, in the Torture Rack, go to the Condo Fawn, for Cassie Save Plan.
I tried talking to Arlene at the police station but "nevermind" was my only conversation option. I haven't tried talking to Fawn at the torture rack, only at the condo. Maybe I'll try advancing her story and see if that resets anything.
