/Recurring Characters/

[Season 1] "Deep Throat" (Jerry Hardin) is a mysterious individual believed to be some sort of higher-up government official. Mulder contacted him via a blue light shining from his apartment window; DT called Mulder and signaled him with a series of clicks [E.B.E.]. The method of choosing a meeting place was not determined. He appears to have been exterminated in the episode "The Erlenmeyer Flask."

Speculation on Deep Throat is contained in Internal Affairs X-File Inquiry #875110-6249 [aka the Deep Throat FAQ, posted by Special Agent Jeff Gostin].

[Season 1 and 2] "Cigarette Smoking Man" (William B. Davis) is another mysterious individual who, like Deep Throat, appears to be a higher-up government official with some power. Assistant Director Skinner seemed to be deferring to his opinion early in our notice of him [Tooms] but Skinner ordered him out of his office during a discussion with Mulder after the agent had abandoned his assignment to investigate possible alien contact in Puerto Rico [Little Green Men]. CSM apepars to be back in power, however [F. Emasculata, Anasazi].
CSM has also kept a silent watch on the proceedings in Blevins's and Skinner's offices and buried vital evidence in a secret Pentagon storage room [Pilot, Erlenmeyer Flask]. He also used Special Agent Alex Krycek to keep an eye on Mulder and any of Mulder's investigations [Sleepless, Duane Barry, Ascension]. Mulder pulled a gun on him and threatened him with death in his studio apartment (at 900 W. Georgia St.) [One Breath]. He seems to be an acquaintance of Mulder's father Bill [Anasazi].

[Season 1 and 2] "Lone Gunmen" Byers (Bruce Harwood), Langly (Dean Haglund), and Frohike (Tom Braidwood) are three of Mulder's sources who work at "The Lone Gunman," a publication dealing with perceived government conspiracies. Frohike has a crush on Scully [E.B.E., Little Green Men, One Breath; Fearful Symmetry]. He seemed to have a role in Mulder and Scully's assignment to a manhunt for escaped convicts [F. Emasculata]. A fourth Lone Gunman, computer hacker The Thinker (Bernie Coulson), has put Mulder and Scully in grave danger by obtaining a copy of a classified government document [Anasazi].

[Season 1 and 2] Margaret Scully (Sheila Larken) is Dana Scully's mother [Beyond the Sea, Ascension, One Breath]. She has had certain unexplained perceptions about her daughter [Ascension], leading to indications that Scully herself may be extranormally perceptive [Aubrey].

[Season 2] Special Agent Alex Krycek (Nicholas Lea) moved into the role of Mulder's partner with the unexplained murders of former Vietnam veterans [Sleepless]. We discovered, however, that Krycek had a hidden agenda, as a lackey for Cigarette Smoking Man: keep an eye on Mulder and keep him from finding out information that would bring certain covert activities to light [Sleepless, Ascension]. With the disappearance of Dana Scully and the reopening of the X Files, Krycek himself disappeared [Ascension]. He reappeared, briefly, to murder Mulder's father and attempt to kill Mulder himself, but was able to make his escape. [Anasazi]

[Season 2] "X" (Steven Williams), an acquaintance of Deep Throat, is even more mysterious than his predecessor. X's information is even more reluctantly shared. Mulder is able to contact X by taping an X to his front window and shining a light through it [One Breath; Colony; End Game]. X seems to be involved with a different covert group than Cigarette Smoking Man's; he kidnapped a scientist with vitally powerful information concerning an illicit experiment. [Soft Light.]
