Jeremiah. Mulder returns to the hospital to see his mother, resigned to the fact that he cannot save her. The Syndicate leads X to a trap at Mulder's apartment, where he is shot by the Grey-Haired Man. X crawls into the apartment and writes the letters "SRSG" in his blood before dying. The letters lead Mulder to Marita Covarrubias (Laurie Holden), the assistant to the Special Representative of the Secretary General of the United Nations. Covarrubias tells Mulder that the fields in Canada have been abandoned, but shows him a picture of the drone children tending to the shrubs. At the hospital, the Smoking Man directs the Bounty Hunter to heal Mulder's mother, telling him that the fiercest enemy is the one with nothing to lose. Production The appearance of Samantha Mulder, this time as a clone of her from when she was still a little girl, was due to series creator Chris Carter's desire to bring her back. Carter felt Samantha was an important element of the show, referring to her as being part of the lifeblood of the series. The decision to kill the character X was made at the end of the third season. The writers felt that they could only do so much with the character and decided that they would either make him a bigger player on the show, or have him pay the price for collaborating with Fox Mulder. Ultimately they decided on the latter. This led to the introduction of Marita Covarrubias at the end of the episode, Mulder's latest informant. The exterior shots of the crop fields in the episodes were filmed in ginseng fields, which writer Frank Spotnitz felt had an "otherworldly" quality to them. These fields were located near the city of Kamloops, which is approximately a three-and-a-half-hour drive from Vancouver; a location from which the production had rarely strayed during its first five seasons. The hair, makeup and wardrobe truck ended up getting lost while driving there. A fiberglass composite lattice used by the aircraft industry was used to create the honeycombs through which the alien bounty hunter chases Mulder. The death of X was a prominent scene in the episode, and it took several takes to complete the final scene; with Spotnitz feeling that "it was a good way to send him off". Director R. W. Goodwin has noted that he is responsible for directing the episodes that
