Lieutenant Disher: Monk, what's goin' on?
Adrian Monk: Did you see that?
Lieutenant Disher: See what?
Adrian Monk: That guy. Whitman. He got to the door, then he stopped. He's done time. In prison, you never open your own door. They open them for you, and after a while, it becomes a habit. He must have just been released.
Lieutenant Disher: Okay, so, he's done time.
Adrian Monk: Look. He just handed me this. Look how it's folded. Four corners to the center, then in half, and half again. In my whole life, I've only ever seen one piece of paper folded like this.
Lieutenant Disher: The sniper's note.
Adrian Monk: He's the guy.
Lieutenant Disher: Why? What's he after?
Adrian Monk: I don't know.
Lieutenant Disher: But he's the guy.
Adrian Monk: Oh, yeah.
