Adrian Monk: Are you following us?
Harold Krenshaw: I think you're following me.
Natalie: Harold, we were here first. We came straight from Dr. Bell's.
Harold Krenshaw: A lot of his patients come here, because it's right across the street. For example, that guy over there.
Adrian Monk: He's not even in our group.
Harold Krenshaw: Not anymore. He left the nest five weeks ago. That's Xavier Danko. He's completely cured. He was more screwed up than anybody.
Natalie: What was wrong with him?
Harold Krenshaw: He was obsessed with an exotic dancer named Tiffany something. He was following her. He got better. I want to be next. I want to get better too. That's why you have to leave the group, Adrian. You're ruining everything.
Natalie: Mr. Monk has every right to be there, Harold.
Harold Krenshaw: No, he doesn't.
