He sprayed them almost right after they said are you in thr wrong car . They had nothing to fear in the short time he got in the car . The main chick clearly had her own issues as the movie so we know why she didn't . She thought she could reach Kevin and didn't think he was a threat to himself or anyone else physically. We know what was really going on she thought he was trying to deal with the incident at his job where he was harassed . Kevin was her patient for along time she thought she could reach him . She had no reason to think he kidnapped 3 girls . Some of the stuff you say is illogical are only because you see everything. The girl didn't know what was going on with Kevin and once she said his name she thought he was ok until he turned back to hedwig and she was scared because she saw he was a murderer by that point . It's not as easy as you making itBreh, there is no world in which the psychiatrist does not call the police to let them know of her concerns. Thats a responsibility of people who practice. If there is concern for imminent danger to life, like there was when before decided to go to the building, she has to call the police. And while the girls thought he was in the wrong car, no one screamed or tried to leave the car. Also, why did homegirl sit and listen to the story of the bad guy instead of just running when she had the chance, before he turned back into "The Beast." Why didn't the psychiatrist just say his full name if that was the trick to confusing him?Why did the old woman not just leave when she had the chance instead of opening the door. She knew something was going on and could have left then. Like so much illogical sh!t that I cannot count.
