"Never Again" is the thirteenth episode of the fourth season of the American science fiction television series The X-Files. It was written by producers Glen Morgan and James Wong, and directed by Rob Bowman. The episode aired in the United States on February 2, 1997, on the Fox network and in the United Kingdom on BBC One on December 3, 1997. The episode is a "Monster-of-the-Week" story, a stand-alone plot which is unconnected to the series' wider mythology. The episode received a Nielsen rating of 13 and was viewed by 21.36 million viewers. It received mostly positive reviews from television critics.

The show centers on FBI special agents Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson) who work on cases linked to the paranormal, called X-Files. Mulder is a believer in the paranormal, while the skeptical Scully has been assigned to debunk his work. In this episode, Scully leaves town—and Mulder—for a solo assignment. She soon meets Ed Jerse, a man who is being mentally controlled by a drug-related side effect of his tattoo. His tattoo, affectionately named Betty, does not want to share him, especially not with Scully.

Although "Never Again" was directed by Bowman, it was originally scheduled to be directed by film director Quentin Tarantino. Tarantino was unable to direct the entry due to a dispute with the Directors Guild of America. Gillian Anderson was particularly pleased with the episode showing a different side of Scully; she had specifically asked Morgan and Wong to write an episode that explored Scully's dark side. Several cast members from Morgan and Wong's series Space: Above and Beyond were cast in the episode.

Plot

In Philadelphia, Ed Jerse loses a divorce settlement to his ex-wife, who has sole custody of his children. After getting drunk at a bar, Ed wanders into a tattoo parlor and impulsively receives a tattoo depicting a Sailor Jerry-like pin-up girl with the words "Never Again" under her image. At work the next day, Ed hears a woman calling him a "loser"; he has a violent confrontation with a female co-worker—who denies saying anything—and is subsequently subdued.

Never Again (The X-Files)

In Washington, Agents Fox Mulder and Dana Scully conduct a discreet meeting with a Russian informant, Vsevlod Pudovkin, who claims to have seen a UFO at a secret research center. Upon returning to FBI headquarters, Mulder heads out on vacation to visit Graceland, leaving Scully to follow up on the Pudovkin case for him. Scully is uninterested in the case and expresses serious doubts about Pudovkin's credibility, leading to an argument with Mulder. Scully becomes upset over the direction her life and career are going.

Meanwhile, Ed is fired via telephone. He hears the same voice as before and yells at the woman living below him, thinking it was her. Upon hearing the voice after a pair of Jehovah's Witnesses stop by, Ed goes downstairs and murders his neighbor, throwing her body in the furnace. When the voice talks to him again, Jerse realizes it is coming from his new tattoo. Scully heads to Philadelphia and watches Pudovkin enter a tattoo parlor. Inside, she sees Ed arguing with the owner, wanting the tattoo removed. Ed strikes up a conversation with Scully and invites her out to dinner, which she initially declines.

That night, Scully talks to Mulder over the phone and informs him that Pudovkin is a con man and part of the Russian mafia. Frustrated by the conversation, Scully calls Jerse and tells him that she changed her mind. At a nearby lounge, Scully is concerned about Ed's arm, where he has burned the tattoo with a cigarette butt. Ed convinces Scully to get a tattoo, and she has one of an Ouroboros applied to her back. Scully stays at Ed's apartment. The tattoo is angry at him, saying she will be dead if he kisses her, which he does anyway.

The next morning, two detectives arrive at the apartment after Ed goes out, telling Scully that Ed's neighbor is missing and blood was found in her apartment with an unusual chemical substance in it. Scully researches the material on Ed's laptop and tries to call Mulder, but hangs up before Mulder has a chance to answer. When Ed arrives, Scully tells him that they found blood in his neighbor's apartment and that it was likely his. She thinks that the chemical came from the tattoo ink and wants them both to head to the hospital to be tested. Ed tells Scully about the voice he has been hearing from his tattoo.
