Deep Throat directs Mulder to a crime scene where police are looking for a suspect who evaded capture and jumped into the river near an industrial area. Finding that evidence has been covered up, Mulder and Scully question a doctor whose car the suspect had driven on a high-speed chase with police. Later, the doctor is murdered by a man who was investigating the crime scene at the behest of an unknown agency.

Scully: You don't know that this isn't just a game with him. He's toying with you. Rationing out the facts. Mulder: You think he does it because he gets off on it? Scully: No. I think he does it because you do.
