"Fearful Symmetry" is the eighteenth episode of the second season of the American science fiction television series The X-Files. It premiered on the Fox network on . It was written by Steve De Jarnatt and directed by James Whitmore Jr. The episode is a "Monster-of-the-Week" story, only loosely connected to the series' wider mythology. "Fearful Symmetry" received a Nielsen rating of 10.1 and was watched by 9.6 million households. The episode received mixed reviews from critics but later won an EMA Award.
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, Mulder and Scully investigate the death of a federal construction worker and the destruction of various property that can only be tied to an escaped elephant. Unfortunately, the only witnesses claim to have seen no animals which might have caused the turmoil. Soon, Mulder and Scully discover the local zoo whose claim to fame is that they've never had a successful animal birth.
"Fearful Symmetry" takes its title from a line in the William Blake poem "The Tyger". Filming for the episode faced several hurdles. Live elephants and tigers were used. Co-Producer J.P. Finn claimed that the hardest part of filming the episode was getting an elephant. The biggest hurdle when filming scenes with the tiger were keeping it "calm and warm", due to the cool nature of Vancouver.
Plot
In Fairfield, Idaho, two janitors witness an invisible force storm down a city street; a road worker is later killed by the force on the highway. The next day, an elephant suddenly materializes in front of an oncoming big rig. The driver manages to stop in time, but the elephant soon collapses and dies, over forty miles away from where it disappeared the night before at the Fairfield Zoo.
Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson) survey the damage in the city, which appears to have been caused by an elephant even though none was seen. Ed Meecham, an animal handler at the zoo, recounts how he came to the elephant's locked cage to find it empty. His boss, Willa Ambrose, tells the agents that the zoo is in danger of closing due to other animal disappearances. She blames the zoo's decline on an animal rights group which is known to free captive animals. The group's leader, Kyle Lang, denies any involvement in the elephant's release. Lang tells them that Ambrose is being sued by the Malawi government over a lowland gorilla she took from their country ten years prior.
Mulder contacts Frohike and Byers, who say that Fairfield is known for its animal disappearances and UFO sightings. They also mention Ambrose's gorilla, who is known to communicate using American Sign Language. Meanwhile, Scully follows one of Lang's activists as he sneaks into the zoo, running into Meecham inside. The activist attempts to free a tiger, but after a flash of light, the tiger seemingly disappears. The activist is promptly mauled to death, with the killing captured on his night vision camera. When questioned, Lang denies any responsibility for the death. Ambrose introduces the agents to the gorilla, Sophie, who has been cowering in her cage and expresses an apparent fear of light.
Scully performs a necropsy on the elephant, revealing it to be pregnant — which is impossible, since the animal had never been mated. The tiger reappears at a Boise construction site, and is shot dead by Meecham when it charges at Ambrose; the zoo is shut down the next day over the incident. Mulder tells Ambrose that the tiger was also pregnant, and explains his theory that extraterrestrial aliens are impregnating all the female endangered animals as part of "their own Noah's Ark." Mulder thinks that Sophie too is pregnant and that she is worried that her baby will be abducted. Sophie confirms Mulder's suspicions when she makes signs for "baby go flying light".
