"Closure" is the eleventh episode of the seventh season of the science fiction television series The X-Files, and the 150th episode overall. It was directed by Kim Manners and written by series creator Chris Carter and Frank Spotnitz. The installment explores the series' overarching mythology and is the conclusion of a two-part episode revolving around the final revelation of what really happened to Fox Mulder's (David Duchovny) sister, Samantha. Originally aired by the Fox network on February 13, 2000, "Closure" received a Nielsen rating of 9.1 and was seen by 15.35 million viewers. The episode received mostly positive reviews from critics; many felt that the final reveal was emotional and powerful, although some were unhappy with the resolution.

The show centers on FBI special agents Fox Mulder (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, but the two have developed a deep friendship. In this episode, after Mulder is forced to accept that his mother's death was by her own hand, he is led by a man whose son disappeared years earlier to another truth: that his sister, Samantha, was among the souls taken by ‘walk-ins’, saving the souls of children doomed to live unhappy lives.

"Closure" was a story milestone for the series, finally revealing Samantha's fate; this story-arc had driven a large part of the series' earlier episodes. The episode was written as a continuation to the previous episode, "Sein und Zeit," but branched off into different territory. Although a majority of the episode was filmed on a soundstage, several scenes were shot on location, such as the scenes at the former Norton Air Force Base in San Bernardino, California. Several of the sequences, specifically those featuring the souls of dead children, required elaborate filming techniques. The episode has been analyzed due to its themes of belief and hope.

Plot

Background

For the first five seasons of the series, FBI federal agents Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson) sought to gain understanding about the disappearance of Mulder's sister, Samantha, who was abducted when Mulder was 12 years old.Kowalski (2009), pp. 243–246. In the previous episode, "Sein und Zeit", Mulder and Scully tracked down a serial killer who targeted children. While investigating the case, Mulder began to get emotionally involved, due to the similarities with his sister's disappearance.Shapiro (2000), pp. 119–128.

Events Mulder and Scully aid the Sacramento Police in the investigation of a brutal murder committed by Truelove, the owner of the Santa Village. As the remains of more children are discovered, he admits killing twenty-four children, but denies murdering Amber Lynn LaPierre, who disappeared from her home in the previous episode. Mulder is approached by psychic Harold Piller, who tells Mulder that he has helped law enforcement across the world, and has proved in various cases that children had been taken by "walk-ins", beings composed of starlight. Piller believes that walk-ins save children who suffer terrible fates.

Scully becomes worried about Piller's influence over Mulder. The agents return to Washington, D.C., where Mulder keeps searching for evidence in the case. Meanwhile, Piller gets a vision of Mulder's mother, who recently died by suicide, leading Mulder to April Air Force Base. Scully finds evidence that Samantha's disappearance is linked to The Smoking Man (William B. Davis); when she returns to her apartment, she finds him waiting for her. He tells her that he had called off the search for Mulder's sister when she vanished because he knew she was dead.

When Mulder returns to April Air Force Base, he uncovers proof that Samantha lived with the Smoking Man along with his son, Jeffrey Spender, and that she was forced to undergo painful tests. Scully finds a 1979 police report of a girl matching Samantha's description, and learns that she was taken to a hospital emergency room. She and Mulder find the nurse who treated her, and the nurse describes how Samantha disappeared the same way as Amber, without a trace. Mulder later walks through the forest and receives a vision of Samantha along with the spirits of other children, including Amber Lynn. Upon telling Scully and Piller of his vision, Piller reacts badly upon hearing that his son is dead, while Mulder accepts that his sister is dead and in a better place. When Scully comforts Mulder and asks if he is all right, he responds with a choked "I'm fine. I'm free."Shapiro (2000), pp. 130–139.

Production

Writing

"Closure," written by series creator Chris Carter and executive producer Frank Spotnitz, brought an end to Mulder's quest for his sister, Samantha, who had been abducted when he was a child. While the idea to close the story arc received mixed reactions from various production and crew members, many realized that the time had come for the show to answer one of its biggest questions. Spotnitz explained that, "I think [series star, David Duchovny] grew tired of playing the man who is missing his sister. [...] I told him, 'This is going to be the last time you're going to have to play [that part].'" Paul Rabwin noted that, "It's been seven years. I don't think any of us are going to miss Samantha Mulder. That device and motivation were very strong in the early years of the show. But as the years have gone by, the speculation kind of melted away."Shapiro (2000), p. 139.

"Closure" continued where the previous episode, "Sein und Zeit", left off but branched off into different territory. Carter later explained that, "emotionally, it was heavy stuff for everybody, but necessarily so. These episodes involved two very personal cases, the search for a serial killer [in 'Sein und Zeit'] and the search for Mulder's sister [in 'Closure']." Marc Shapiro, in his book All Things: The Official Guide to The X-Files, Vol. 6 noted that, in addition to bringing an end to the Samantha story arc, the episode was "very much a [Smoking Man] episode" in that it explored his involvement in Samantha's abduction and revealed to the audience that he was seriously ill. The episode's tagline was changed from the usual "The Truth is Out There" to "Believe to Understand".

Filming Manners argued that "Closure" was one of the first episodes in which the production staff was able to "shoot in Los Angeles with the sun out". Previous to this episode, the show's production staff was "struggling with the fact that we weren't in Vancouver anymore and that our show had suddenly become very bright and cheery". To amend this, Bill Roe, director of photography, used tree branches and c-stands to block out the sunlight. The first scene with the walk-ins rising up from their grave, shot at Griffith Park above the playground, was "tricky," according to director Kim Manners, as he felt uncomfortable telling the children to rise out of "graves", feeling it could psychologically hurt them; instead, he had the crew call the holes in the ground "forts." The scenes taking place at April Air Force Base were shot in San Bernardino, California, at a closed airfield, the former Norton Air Force Base. On the airbase was a large, derelict complex of over 400 buildings (many of them houses) that had been constructed and used by the United States military. According to Manners, the entire area was an "eerie ... ghost town", as many of the houses were still full of old, abandoned furniture. Originally, the producers wanted the name of the fictitious air force base to be "March Air Force Base". However, the presence of a real air reserve base with the same name located less than 10 miles away in Riverside, California, necessitated a change to "April Air Force Base". The scene at the restaurant was shot at the Carriage Inn on Sepulveda Boulevard.

During filming, David Duchovny decided to act out the reunion scene in a manner contrary to what the script called for. Manners later said, "In the script, it called for his sister to run up and hug him, and Mulder was to start crying. David didn't want to cry. I said, 'David, you're finally realizing your sister is, in fact, dead.' […] He said, 'Just watch what I do; trust me.' And, he held that little girl actress—there was a beatific smile on his face that was absolutely astounding." Manners was very happy with the change and included it in the final cut of the episode.Hurwitz and Knowles (2008), p. 177. To create the scene featuring the ghosts of the dead children interacting with the characters, various layers of film had to be overlaid onto each other. The scenes were laborious and took "many passes" to complete. After the shots had been secured, the film of the ghosts had to be made slightly transparent. These scenes were actually shot in daylight, and a specialized "day for night" photography (in which the subjects were illuminated with bright lights and the sky was completely avoided) was used to make the finished scene look as if it had been filmed at night. The scenes were shot at 48 frames a second, twice that of the show's normal filming speed. Rebecca Toolan traveled to Los Angeles from Vancouver specifically for this episode and "Sein Und Zeit". To create her ghostly apparition, the production staff filmed Toolan and superimposed the image over a shot of Duchovny. Manners played the part of the hypnotist in the video that Scully watches, with the director-turned-actor later noting, "I only act when you can't actually see my face". Manners was critical of Duchovny's wig used in this scene—which had been added to make the footage seem older. He sardonically noted that "this is [not] one of the episodes that Cheri Medcalf [the show's make-up director] won an Emmy for."

Composer Mark Snow described his score as possessing a "sense of biblical fervor and religiosity—an elegy—a feeling about it that was so poignant and touching to me."Fraga (2011), p. 124. "My Weakness", a song by Moby from his 1999 album Play, is used in this episode, first when the FBI discover the mass grave and finally at the end when Mulder encounters his sister's spirit. Carter never told Snow about the decision to use someone else's music, although Snow has since said that his reaction to the use of the song was very positive and that the song was a "perfect" fit. Another Moby song, "The Sky is Broken" also from Play, would be featured in the later seventh-season episode "all things".Anderson, 2:07–2:35.

Themes

According to Amy M. Donaldson in her book We Want to Believe: Faith and Gospel in The X-Files, Mulder's opening monologue may be an example of "Mulder now being more receptive to the possibility of God's intervention".Donaldson (2011), pp. 44–45. Throughout much of the series, Mulder has shown a disdain for religion. However, in "Closure", Donaldson points out that "Mulder's belief in God, as always, revolves around his beliefs about his sister's fate". As such, Mulder expresses hope that those who die in a cruel fashion "live on in some other way". Furthermore, she argues that because "Closure" opens with the tagline "Believe to understand", Mulder must "take the leap of faith" in order to find enlightenment, and ultimately the truth about his sister. The first half of the episode plays out according to the tagline; Mulder first believes in "his desire stated in the opening voiceover", and then finds closure.Donaldson (2011), pp. 60–61.
