I guess I'm thinking of this point (ep. 8) forward. She is nice now, but a change is coming, especially if MC cheats or chooses to leave her. Also, I'm wondering, will DPC later on substitute James hallucinations for MC hallucinations? Would that be an episode end cliffhanger? MC is clearly established as being in another location and then we cut to Bella conversing with MC, or so we think. She is then shown to really just speaking to an empty chair. So Bella's underlying mental illness hasn't been solved, it has just been transferred from James to MC. We may have gotten her over James, but now a new fixation has developed.
