I don't think Ally has been hallucinating either. But why are they targeting her? Because of her phobias and "fear is the new currency"?
I am still hung up on two things. In first episode, Chang noted that Hilary lost Michigan by the same count as the number of people in their town. In the last episode, Harrison says "the hive is the perfect natural community, because every single member is completely committed 100% to a singular task. " I think Ally is important to show how fear changes a person . But I think the cult has to be bigger than just a few clowns. How much of the town is involved?
