S3E17 · Pusher

Robert Patrick Modell (Robert Wisden) walks through a supermarket, buying a large supply of protein supplement beverages. Before he can leave, Modell is surrounded and arrested by FBI agents led by Frank Burst (Vic Polizos). While being escorted away in a police car, he repeatedly talks about the color cerulean blue, repeatedly stating "Cerulean blue is a gentle breeze." Modell's talking seemingly causes the driver to not see an approaching semi-trailer truck of that color, causing a collision. Modell escapes after the driver unlocks his handcuffs before dying.

Burst, the only surviving agent of the crash, tells Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson) about his pursuit of Modell—nicknamed "Pusher"—who has committed a series of contract killings over the past two years, making the acts appear to be suicide. Mulder spots the word " ronin " written at the crime scene, and tracks down Modell's classified advertisement in a mercenary magazine. Mulder believes that Modell has the psychic ability to "push" people to do his will. Using the phone number in the ad, the agents track down Modell to a golf course in Falls Church, Virginia, where he makes a SWAT agent pour gasoline on himself and then set himself on fire. Mulder finds Modell exhausted in a car nearby, arresting him.

During his arraignment, Modell uses his ability to make the judge let him go. The agents look into Modell's past and find that he failed to enter the FBI after a psychological examination deemed him to be grossly egocentric and sociopathic. Meanwhile, after writing the word "pass" on a piece of paper and putting it in his lapel, Modell is able to pass security and enter FBI headquarters. He "pushes" a government worker, Holly (Julia Arkos), into pulling up Mulder's file for him. When Walter Skinner (Mitch Pileggi) intervenes, Modell convinces Holly that he was a man who mugged her, causing her to spray Skinner with mace and beat him. Scully is unable to explain how Modell has his power, but now agrees with Mulder's theory that he can push people into doing whatever he wants.

Agents raid Modell's apartment, but find it empty. They find cans of protein drinks in the refrigerator and medicine for epilepsy. Mulder suspects that a brain tumor has given Modell his psychokinetic ability, but that using his power is physically exhausting, forcing him to constantly consume the protein supplements. Mulder believes that he is dying and wants to go out in a blaze of glory. Modell makes a taunting phone call to Agent Burst and causes him to have a fatal heart attack while they try to trace him. The agents track Modell down to a hospital, where he has compelled a guard to shoot an MRI technician and kill himself. Mulder ventures inside the hospital and is captured by Modell.

Scully finds the two sitting at a table with the dead guard's revolver. Modell forces Mulder to play Russian roulette with him. Despite Scully's pleading, Mulder pulls the trigger first at Modell and then himself, the hammer falling on an empty chamber both times. Modell then makes him aim the gun at Scully. At the last instant, Scully sees a fire alarm in a mirror and pulls it, breaking Modell's concentration. Mulder instantly switches his aim to Modell and pulls the trigger. The bullet is fired and Modell is severely wounded.

Later, Mulder and Scully visit Modell in the hospital, where he is lying in a coma from which Scully predicts he will not awaken before his brain tumor kills him. Mulder surprises her by revealing that Modell's brain tumor was operable at all times, but he refused to have it removed, even as his health deteriorated. Scully asks why, and Mulder repeats her earlier assessment of Modell — that he was always a "little man", and his psychic ability made him feel big.
