 Trivia

• The rock band Eve 6 took their name from a character in this episode.
• Eve 6 says, "I am her, and she is me, and we are all together," which is a reference to the first line of the song "I Am the Walrus" by The Beatles. ("I am he as you are he as you are me, and we are all together").
• The characters of Teena and Cindy were named after the wives of Glen Morgan and James Wong, who rewrote the original script prior to filming. Chris Carter said in The X Files Official Season 1 book and in Season 1 DVD Extras that Erika's character name was in honor of Glen Morgan first wife, Cindy, but in real life her mother is also called Cindy.
• This is the first episode to mention supersoldiers, a recurrent theme in Seasons 8 and 9.
• This episode was originally called "The Girls from Greenwich," a reference to the similarly themed The Boys from Brazil (1978).
• The footage shown on the television (Eek the Cat! and following news segment) is the same footage used in Human Essence (1998).
• The story has many similarities to the bizarre true story explored in the documentary Three Identical Strangers (2018).
• When Harriet Sansom Harris guest-starred on Frasier (1993), she played a character who makes herself sick by ingesting digitalis, the poison of choice of Eve 6 in this episode.
• At one point, it was considered using digital effects to create the twins.
• Garry Davey who plays Hunter would go on to appear in other episodes of The X Files, playing Dr. Keats in Roland (season 1), the Captain in End Game (season 2) and Bob Spitz in Syzygy (season 3).
• This episode has strong similarities to the 1982 film Anna to the Infinite Power, which deals with a teenage girl who discovers she's part of a cloning experiment.
• This is the 11th episode of season 1. The number 11 being a twin number.

spoilers

• Mary-Kate Olsen and Ashley Olsen were briefly considered to play the two evil twins. However, stricter US child labor laws precluded the casting of Americans in the roles, so they cast twins from the Vancouver, BC, Canada filming area instead.

Goofs

• At the truck stop diner Mulder and Scully stop at with the two girls, a key is needed to enter the restrooms. However, the doors on the restrooms have no outer locks or keyholes.
• When Mulder first picks up his soda which has been spiked with foxglove, the spilled green foxglove liquid is vaguely visible around the bottom of the cup, positioned just behind the two rivets on the table from the camera's perspective. When he returns to pick up his keys, however, the green spill has moved to a different spot in front of the rivets. It is also a much darker green color, and has an almost crystalline appearance, whereas it had previously been a light green-colored liquid.
• When the second girl was abducted, Scully reports to the cop that Sally fled in a light blue '93 Corolla. But when Sally gets to the motel in Point Reyes, she arrives in a dark blue Pontiac Bonneville.
• The girls say they cultivated the foxglove themselves. The powdered foxglove is then kept in a vial. The powder looks very green, like peas. Real dried foxglove looks brownish with a tint of whatever colour the flower was (usually purple).

Spoilers

• The dr*g used by the twins to poison others is said to be extracted by a plant called digitalis, supposedly from South America. Digitalis purpurea, the common foxglove, is in fact European (particularly common in what is now the UK) and was well known in the middle ages as a heart stimulant. Being a stimulant, its effect on someone who ingested it would also not have been paralysis, as stated in the episode. The death cause should be a heart attack, instead.
• A Canadian flag is reflected in the "NO VACANCY" sign outside the motel that is supposed to be situated 40 miles north of San Fransisco.
• Highway 49 in California is nowhere near Point Reyes.
• Character error
• Part of the plot line takes place in Point Reyes, yet Mulder refers to this town as Port Reyes.
• The doctor's name is "Dr. Sally Kendrick," and most characters refer to her by that name, including Dr Kendrick herself in the video seen at the clinic, and Scully when she is reviewing the patient history form. But when discussing the video with Mulder, Scully calls her "Kendricks".
