"Cigarette-Smoking Man", another mysterious individual who, like Deep Throat, appears to be a higher-up government official with some power, though not the person calling the shots -- he seems to be answering to Well-Manicured Man [The Blessing Way/Paper Clip]. His silent presence (first he said something in "Tooms") with a "Morley" cigarettes in Skinner's office is always a warning that the shadowy government attempting to discredit Mulder is again keeping an eye on the nonconformist agent. 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]. He has access to the basement of the Pentagon, and when he's not obfuscating the Truth, he's rewriting it. CSM appeared to be back in control [F. Emasculata; Anasazi], but ended up making a deal with Skinner in order to keep the information from a confidential document from becoming public [Paper Clip]. He now has the disk [Apocrypha]. He also possesses secret files of Japanese war experiments [731].
Before "The Blessing Way" he looked as if he was the leader of whatever conspiracy it is that is trying to suppress Mulder's work. However, from season 3 onwards we learn that he is only one of a group of men. He is their "associate in Washington", and often manages to get things wrong and has lie to them about it. In "Redux" he complains that he was "cut out of the loop" on surveillance of Mulder. Seeing his influence slip away, he tells the Elder that they need his expertise, and that Mulder is his alone. They are not convinced, for he is later shot by an assassin called Quiet Willy. CSM has also kept a silent watch on the proceedings in Blevins' and Skinner's offices and buried vital evidence in a secret Pentagon storage room [Pilot, Erlenmeyer Flask]. He has tried to get Skinner removed from his position by framing him for murder [Avatar]. He also used Special Agent Alex Krycek to keep an eye on Mulder and any of Mulder's investigations [Sleepless, Duane Barry, Ascension, Paper Clip]. Mulder pulled a gun on him and threatened him with death in his studio apartment (at 900 W. Georgia St.) [One Breath]. Later [Musings of a Cigarette-Smoking Man] is his address given as Mr. Raul Bloodworth / 555 Brooksbank Ave, Apt. 24 / Washington, D.C. / 20091. Then [The Red and the Black], he lived in North Hatley, Quebec. His latest address was Watergate Apartment #2645, Washington D.C. [Requiem]. He seems to be an acquaintance of Mulder's father Bill [Anasazi, Piper Maru], and a more intimate acquaintance of Mulder's mother [Talitha Cumi], who he had healed through alien means from the effects of a stroke [Herrenvolk]. He may be responsible for Bill Mulder's murder, and he is certainly responsible for several attempts on the life of the X-Files agents [Anasazi, Piper Maru].
He has also apparently blocked research on the alien life form from Tunguska, Russia, by the Well-Manicured Man and his consortium [Tunguska/Terma]. He negotiated with Assistant Director Skinner for a possible cure of Scully's cancer [Memento Mori], and ordered him to eradicate all evidence related to a mistaken murder caused by smallpox-carrying bees. He also appears to be directing Marita Covarrubias's activities [Zero Sum]. In "Redux" he complains that he was "cut out of the loop" on surveillance of Mulder. Seeing his influence slip away, he tells the Elder that they need his expertise, and that Mulder is his alone. They are not convinced, for he is later shot and apparently killed - by an assassin called Quiet Willy. He resurfaced in "The Red and the Black", hiding out in a cabin in a place called North Hatley, in Quebec. How he escaped death is not yet known. Later, he reunited with the rest of the Consortium, both sides prepared to forgive and forget (though no doubt still with lots of hidden agendas) [The End]. By this time, CSM seems to have given up on Mulder and be focusing on Spender instead as the person he wants to join him. In "The Beginning", he calls Spender "son" liberally, and congratulates him on doing everything he asked. He is now positively gleeful about destroying Mulder. His menace may be fading, however, as both the Well-Manicured Man he answered to and Alex Krycek, his tool who has turned against him, threaten to bring upon him a justice Mulder and Scully cannot. After the death of the whole American branch of the Consortium he answers only to himself, but he still has Krycek to contend with. He has no children or family, except his apparently dead [One Son] son [The Red and the Black] Jeffrey Spender and his wife Cassandra Spender. Mulder's alien DNA is transferred to the CSM in order to make him a hybrid [The Sixth Extinction II: Amor Fati]. But the procedure caused a cerebral inflammation in the elusive smoker. Although the old man is already dying, his former mercenary, Krycek, tosses the CSM down a flight of stairs [Requiem]. He reappeared in the last episode [The Truth] as a wise man hiding in some Indian buildings in New Mexico only to see Mulder broken, to tell him about the date of final alien invasion (December 22nd 2012), and to die, this time for real.
The nick-name "Cancerman" is first used by Mulder in "One Breath". "Black-lunged son-of-a-bitch" is his other favorite name for him. Later, Scully and even Skinner have come to use it. The pseudonym he uses himself is Raul Bloodworth, and Lee Harvey Oswald calls him "Mr. Hunt". His name can be also Spender, because his son's name is Spender, but Jeffrey could take the name from his mother. He also used an alias CGB Spender [One Son]. He was born on 20 August 1940 in Baton Rouge, Louisiana. His father was executed for treason, having aided the Nazis. His mother died of lung cancer, leaving him an orphan. He then grew up in orphanages around the country. Later he joined the army, which is where he met Bill Mulder. Because of his mother's disease he himself refused to smoke when he was young. He started smoking after Kennedy's assassination, picking up Lee Harvey Oswald's cigarettes. These are Morleys, in a packet that looks rather like Marlboros. His lighter is inscribed "Trust no one" [Musings of a Cigarette-Smoking Man]. In "Talitha Cumi" we find that he does indeed have lung cancer, but he is then cured by Jeremiah Smith, in return for his freedom. This is nice example of CSM putting his own interests above the "project", despite what he says to the contrary. He is a good water-skier (as is William B. Davis). CSM reminds Mrs Mulder that he used to go water skiing with Bill Mulder at their summer house in Quonochontaug, Rhode Island. Bill Mulder was good, he says, but he was better [Talitha Cumi]. He seems to be also a thwarted author. He writes novels (typing on an old-fashioned type-writer) which no-one wants to publish. "Take a Chance" was brutally rejected in 1968. "Second Chance", about alien assassination, was eventually published it is in a seedy magazine ("Roman a Clef"), but the ending was changed. The few times we see him in his apartment, he is sitting alone, watching television, despite the fact that he expresses a decided preference for reading books over watching movies [Musings of a Cigarette-Smoking Man]. Speaks fluent German, but needs a translator to help him with the Japanese. [Season 1, 2, 3, 4, 5, 6, 7, Movie, 9]

Alex Krycek worms his way into the confidence of Fox Mulder in the second season's fourth episode [Sleepless], where he plays his role of worshipful junior FBI agent to the hilt. He even adopts some of Mulder's wry wit ("Well, it puts a whole new spin on 'virtual reality'.") to try to get closer to Mulder. But his true allegiance emerges when he warns The Cigarette-Smoking Man that separating Mulder and Scully has not stopped their partnership, and that the Cigarette-Smoking Man has underestimated Agent Scully as a danger to their secrets.
The darker side of the traitor (whom Internet fans have dubbed "Ratboy" for his faithlessness) appears even more clearly in the "Duane Barry/Ascension/One Breath" trilogy, where he is instrumental in the abduction of Agent Scully and the silencing of Duane Barry. His treachery exposed, he disappears from the Bureau, only to become a greater threat than ever as he goes underground. At the end of the second season, he murders Fox Mulder's father and frames Mulder for the killing [Anasazi].
The bodies mount in the third season, as his ties to the Cigarette-Smoking Man's cadre begin to unravel. He is an accessory to the murder of Melissa Scully [The Blessing Way/Paper Clip] in a botched attempt on Agent Scully's life. When he ambushes Assistant Director Skinner and recovers a vital digital tape, the Cigarette-Smoking Man repays him by trying to have him killed. Krycek escapes the trap and vows revenge on his former mentor, while fleeing the country with the tape that reveals the extent of US government cover-up in alien visitations [Paper Clip]. It is not until Fox Mulder goes to Hong Kong in pursuit of another turncoat that he finds Krycek again, but this time Krycek is possessed by the very alien whose secrets he has been selling [Piper Maru]. The alien uses him to cut a deal with the Cigarette-Smoking Man, which returns the off-worlder to his ship but leaves the ragged, terrified Alex Krycek trapped in an abandoned missile silo in North Dakota, begging to be released [Apocrypha].
After feeding tips to Mulder on the activities of a militia group [Tunguska], Krycek resurfaces once again to join Mulder in his pursuit of a mysterious rock from the "meteorite" that struck the area back in the early 1900s [Tunguska/Terma]. This leads them both to Russia where they are captured and thrown into a gulag [Terma]. Mulder discovers during their captivity that Krycek may not be who he is. Krycek is more than friendly with his captors, who seem to know him rather well. Their captors are performing experiments on the prisoners injecting their arms with a strange substance that has do with the mysterious rock that brought them to Russia. Mulder escapes from the gulag and forces Krycek come along, but they are soon separated when Krycek escapes from Mulder once again and flees into the forest. While running away he encounters a group of one-armed men that live in the woods. He tells them he is an American fleeing from the soldiers that run the gulag, and they take him in. That night, while Krycek sleeps, the men grab Krycek and cut off his arm so that the soldiers cannot experiment on him at the Russian chain gang excavating rock from Tunguska [Terma]. He also appears to be a Soviet double agent [Terma] with an agenda different from his former boss, the Cigarette-Smoking Man. Krycek goes under the name 'Artzen' when dealing with the Russians.
Krycek is next seen with a prosthetic limb in the company of a Russian assassin who had been ordered to dispose of those in America involved with the mysterious rock. Krycek had ordered the assassin's mission and he is indeed not just the renegade agent he appears to be, but much more.
His parents were Russian emmigrants. He can speak Russian. He, however, is American raised [The Red and the Black], despite this. By the time of "Patient X" and "The Red and the Black", he seems to have finished with the Russian thing. Despite being the one who ordered the Russian assassin to put a stop to the Consortium's black cancer tests, this time he is the one who brings the vaccine to WMM and his friends. He does it for a price, of course. The vaccine is referred to as a "bargaining chip". By the end of that episode, he seems to be firmly on the side of WMM in the "we must resist the colonists" camp. He visits Mulder and persuades him to track down the rebel alien and stop him from being returned to the colonists. In "S.R. 819" he infects Skinner with a virus, caused by nanomachines in his blood - a virus which Krycek can control literally with the push of a button. While Krycek is seen to be driving a government agency car, and this perhaps is working for "them", he choses to save Skinner at the end. Why? Did he have a secret agenda himself? Did he want to get a hold over Skinner? This does seem to be the result, anyway, since the episode ends with Skinner asking Krycek what he wants him to do, and Krycek saying "all in good time". Is it a personal hold over Skinner, for his own ends, or is he obtaining him for the Project? In "Two Fathers" he seems to be back in with the Consortium, happily doing a job for CSM. After he killed Kritschgau [The Sixth Extinction II: Amor Fati], he went to Tunisia to try to sell the information he stole from him. CSM found out and had him thrown in jail in Penai Colony, Forj Sidi Touji. Later, CSM asked Marita Covarrubias to bring him back to United States to help him to find a crashed UFO and rebuild the Project. He helps Mulder and gets his revenge by pulling CSM off the stairs in a wheelchair [Requiem]. He dies in the eighth season finale [Existence] after being shot by Skinner. [Season 2, 3, 4, 5, 6, 7, 8, Movie]

Well-Manicured Man is the head of a powerful consortium to whom Cigarette-Smoking Man answers. Who is this man who awes and frightens even the Cigarette-Smoking Man? Tall, grey-haired, poised, impeccably tailored, with a cultured veneer belied by the hooded eyes of a snake, the Well-Manicured Man appears to hold the whip hand in the band of master puppeteers who meet behind the brick facade of the club on West 46th Street in New York City. He is quite open about his willingness to lie, manipulate or even kill to protect his secrets, with the suave arrogance of a man who fears absolutely no power -- except the truth. Whenever we see the Consortium at their base, WMM and CSM seem to be at odds with each other. In "Paper Clip", WMM calls CSM's methods "ridiculously ineffective", and in "Apocrypha" calls him arrogant accuses him of mishandling everything and being too ready to use murder and violence. In "Terma" Cigarette-Smoking Man retaliates with some wonderfully cutting pretend sympathy with WMM for his doctor's death. Contacts Scully in The Blessing Way to warn her about an assassination attempt on her life, because this would attract unwanted attention to his group. Although he appeared to Mulder and Scully to be an ally, he is most likely working at cross purposes to theirs. Given that the attempted murder of Scully in "Blessing Way" was done by CSM's own men [Apocrypha] WMM's warnings to her could be seen as an attack on his colleagues violent methods. He also was masterminding a research project dealing with a strange extraterrestrial life form found in rock in Tunguska, Russia [Tunguska/Terma], which has since ended thanks to intervention by Krycek and Mulder.
He has some sort of country estate at Charlottesville, Virginia. He tells Cigarette-Smoking Man pointedly that he comes here because it is out of the way and he won't get disturbed. There are horses there, and he is seen fondly watching a girl ride one. Dr Bonita Charne-Sayre is his personal physician and probably his lover. She was also conducting experiments into finding the cure for the black cancer until she was killed by a Russian assassin [Terma]. WMM was upset at her death. Scully meets him at Bill Mulder's funeral, where he warns her of the assassination attempt [Blessing Way]. Mulder and Scully both meet him in Victor Klemper's greenhouse [Paper Clip]. WMM tells Mulder all about the project, though he says there's a lot more untold. Scully thinks WMM's just manipulating Mulder. Mulder meets him in "Apocrypha" when WMM tricks him and manages to get lots of information from him while giving none. When in England, he lives in Somerset County in large house with servants. He seems to have a daughter, grandson, and maybe two granddaughters, although they can be just friend of his grandson [Movie]. He committed suicide in the movie. The bomb was for Mulder, and WMM ordered Mulder out of the car and returned to it himself. [Season 3, 4, 5, Movie]

Agent Jeffrey Frank Spender is a young, naive and arrogant FBI agent and a son of Cassandra Spender and Cigarette-Smoking Man, hostile to Mulder and the paranormal, who appears in "Patient X". He is concerned about his reputation, and thinks that any association with Mulder will give him a bad reputation. Fortunately for him, he has a friend in high places (for which see later) who makes sure that nothing bad is entered on his record as a result of his involvement with Mulder. His mother is Cassandra Spender, a wheelchair bound multiple abductee, who's looking forward to being abducted again. She is the eponymous "Patient X". She is, apparently, abducted at the end [The Red and the Black], and later returned [Two Fathers]. She's been turned into the first ever successful alien/human hybrid, with green blood and miraculous healing abilities. If the colonists find out that she exists, they'll have no reason to delay their coming. So, she thinks she should be killed. Jeffrey, in his youth, also had a memory of an abduction, but now dismisses it as simply him recycling ideas implanted by his mother. Jeffrey says that his father left when he was 11, and his mother fell to pieces. He blames her abduction fantasy on this mental breakdown. His father still writes to him, hoping for a reconciliation, but Jeffrey returns the letters unopened. This father is none other than the Smoking Man.
In "The End," CSM meets Spender, who doesn't recognise him, and reveals that he's his father. He urges Spender not to let his career suffer by having any involvement with Mulder, and says that he can help him up the career ladder in the FBI. However, by "The Beginning", Spender seems quite happy to do his new-found father's bidding, taking over the X-Files and keeping Mulder away from things. He was shot (apparently) dead by his father at the end of "One Son" - in February 1999. His face and his whole body were severely burned. He re-appeared much later [William] claiming he was sent by Mulder to get some files from the offices. [Season 5, 6, 9]

She is first seen in "The End", and, like Phoebe, is another old flame. She has longish dark hair, and she was his "chickadee" in 1991, when he discovered the X-Files. She has been also an FBI agent, with an interest in parapsychology. She calls herself a believer, and she and Mulder did some investigations together. The Lone Gunmen say they don't know why they split up, but, whatever the reason, Diana took a posting in Europe and Middle East. At the time of "The End", she has only recently returned, saying that there are things she wants to get back to. "Things" seem to include Mulder, whom she calls Fox, since she muses on how much nicer it would have been for him if he had had a believer as a partner. She was shot through a lung [The End], putting her on life support and with little chance of survival. By "The Beginning", she is well again. She, with Spender, took over the X-Files division. She lives in Watergate [Two Fathers]. Fowley is revealed as CSM's confidant [Two Fathers]. Scully and the LGM find that she wasn't ever doing what she claimed she was doing in the Middle East. Instead, she was visiting Tunisia. Also, she has been visiting various MUFON groups, collecting data on abducted women. She was murdered [The Sixth Extinction II: Amor Fati]. [Season 5, 6, 7]

Assistant Director Alvin Kersh is the new boss that Mulder and Scully are assigned to at the start of season six. His first speaking appearance comes in "Drive". He certainly makes no allowances for Mulder and Scully - and why should he? He insists on scrupulous paperwork, and bills them for expenses incurred on unauthorized work. When Mulder complains, he says that he could always quit. He also refuses to accept Scully's "he's been through a lot" excuse, saying "And you apologize for him a lot. I've noticed that about you." He goes on to say that he does not care that Mulder and Scully saved lives; what he cares is that they no longer investigate X-Files, and the sooner the two of them realize that and act accordingly, the better.
Of course, the Consortium would like it if Kersh successfully forced Mulder and Scully to quit, but this doesn't mean that he's doing their work. He might just be doing his job. He's FBI. Mulder and Scully have flaunted a whole host of FBI regulations. Rebuking then for it is proper procedure. CSM is in his office in "Triangle". However, CSM used to hang out in Skinner's office long after Skinner was on Mulder and Scully's side. CSM seems to have certain influence within the FBI, giving him legitimate reasons to do this. Kersh apparently handed over the paper that Scully had, but CSM was in the room at the time he may have had no choice. Maybe...
Since Mulder and Scully got the X-Files back, he is no longer their boss, as the X-Files are under Skinner's supervisory [One Son]. Kersh returns at the beginning of season eight, and he was promoted to Deputy Director. His first act in his new capacity was sending the ambitious Doggett to the basement, literally as well as figuratively, by saddling him with the X-Files.
He also has a secretary: while we don't know her name, she has quite a definite character. Pretty, with blonde hair about the same length as Scully's, she is obviously after Mulder. When Mulder's body is inhabited by Morris, the MIB [Dreamland], it takes only a few words from him to (apparently) invite her round to his apartment and into his bed. She seems to quite enjoy discomforting Scully, when she discovers the liaison. It is only to be assumed that Mulder, when back in his body, surely had some serious explaining to do, when she found he couldn't even remember their encounter. [Season 6, 8]

Another member of the secret 'West 46th Street' consortium who is distrustful of Smoking Man, often seems to be the leader of the group. He feeds false information to Scully in "731" in a boxcar similiar to the one she remembered from her abduction. He is the one CSM complains to when he feels left out of the surveillance of Mulder [Redux] and is the one who orders that the situation be taken care of - which results in the shooting of CSM [Redux II]. Earlier, he has been seen trying to get the group back to business when CSM and WMM are all too ready to let it dissolve in mutual attacks and shifting of blame. In "The Red and the Black", when WMM wants to support the rebels against the colonists, he opposes this, saying survival depends on co-operating with them. When it comes to handing over the captured rebel alien, he acts unilaterally, not consulting WMM until after the fact. After the alien rebels kill the whole American branch of the Consortium, he is between the victims. [Season 3, 4, 5, 6, Movie]

He appears in "The Blessing Way" and "Paper Clip". Returns in "The Movie". [Season 3, Movie]

Elder #3 appears in "The Blessing Way", "Paper Clip" and "Zero Sum", "Patient X", "The Red and the Black", "Two Fathers" and "One Son", where he gets killed by an alien who then assumes his face. [Season 3, 4, 5, 6, Movie]

Another Elder appears in "The End", "The Beginning", "Two Fathers", where he dies and in "One Son". [Season 5, 6]

Michael Kritschgau is a Department of Defense agent and "Roush" employee who convinces Scully that Mulder has been fed lies all along. But first, he steals the ice core tube and attacks Scully. She finds out that he worked in the US Army and that he is now attached to the Pentagon Research Facility in Sethberg, Virginia. He tries to explain Mulder how all the hoaxes are done and that all that Mulder believes is just a fiction invented by the DoD. His regression hypnosis, the story of his sister's abduction, the lies they fed his father, UFO sightings, alien biology, everything. All their disinformation date back to the Korean War. He helps Mulder to find a cure for Scully's cancer, hoping he will also find a cure for his son's Michael Jr.'s terminal disease, contracted in the Gulf War. However, his son dies [Redux II]. He was killed by Krycek [The Sixth Extinction II: Amor Fati]. [Season 4, 5, 7]

Quiet Willy was sent by First Elder to shoot Cigarette-Smoking Man [Redux II] and is later killed on the bridge [The Red and the Black]. His face is assumed by the Bounty Hunter. [Season 5]

Scott Ostelhoff is a Department of Defense employee living in the apartment above Mulder and was assigned to spy on Mulder through his ceiling. He was funded partly by the DoD, and partly by "Roush", and was making reports to someone in the FBI - later revealed as Blevins. He was the man Mulder killed in self-defense, and passed the body off as his own [Gethsemane]. Just for the matter of interest, his ID# is: 983-9436-365. [Season 4, 5]

Gray-Haired Man is a henchman for the Consortium, who is usually sent out to kill various people working at odds with the Consortium, specifically with Cigarette-Smoking Man, to whom he also serves as a driver. Causes Skinner's wife's accident when he runs her off the road [Avatar]; mortally shoots Mr. X in front of Mulder's apartment [Herrenvolk]; shoots at Mulder in the Lombard Research Facility and is responsible for Kurt Crawford's [Memento Mori] and tries to frame Skinner [Zero Sum]. [Season 3, 4, 5]

Red-Haired Man aka Malcolm Gerlach is the assassin with the piano wire on the train [Nisei/731]. He is able to sacrifice his own life for the carried entity, although he doesn't even know what it is. When the vagon is detached from the train and X comes to save Mulder, he is shot by X and dies when the bomb explodes. [Season 3]

Crew Cut Man is Deep Throat's [Erlenmeyer Flask] and 'man in the blue car''s [Red Museum] assassin. He is killed by Sheriff Mazeroski in "Red Museum". He becomes file number XWC060361. His identity was not determined. His name, any record or artifact of his past, present or immigration status were not found. His fingerprints are not on file in either the FBI or National System of Records. [Season 1, 2]

Keeping questionable company, this man in the employ of Cigarette-Smoking Man (not the whole Consortium) first shows up at the start of the third season. Worked with Krycek for a while, then tried to kill him [Paper Clip]. Kills Melissa Scully [The Blessing Way], mistaking her for Dana Scully. He's captured by Scully [Apocrypha] and killed in prison. [Season 3]

Section Chief Scott Blevins is with the Violent Crimes Section of the Bureau [Pilot]. Blevins assigned Scully to be Mulder's partner, and her field reports were sent to his office [early episodes]. Appears in several episodes as Mulder and Scully's superior, though in "Conduit" he makes clear that there are several other people in the chain of command between Mulder and him. He does finally reappear on the end of fourth season, when he heads the committee that listens to Scully's denouncement of the X Files investigations [Gethsemane] In "Redux II" it is revealed that he was the man within the FBI who was receiving the reports from the man who was spying on Mulder. Perhaps because his cover was blown, Blevins is assassinated by a Senior Agent who makes his death appear like suicide [Redux II]. [Season 1, 4, 5]

Section Chief Joseph McGrath is head of the Office of Professional Responsibility [Fallen Angel] and seemed determined to have Mulder fired and the X Files shut down. When Deep Throat overturns the decision, he is furious. He says this was "our" best chance of getting Mulder out of the FBI. Does this suggest he is one of "them"? Or does "we" just mean the FBI, which is always embarrassed by Mulder's flouting of the rules? [Season 1]

A pilot is how the viewers are introduced to this character, but that is not an appropriate name for this alien shape-shifter whose goal is to eliminate any evidence of an extraterrestrial presence and who can morph into anyone. He has been working for Cigarette-Smoking Man when he was sent to heal Mrs Mulder [Herrenvolk]. Why 'Pilot'? When he first appears [Colony], he's believed to be a Russian fighter pilot who crashes in the Arctic. He has been on the Earth as early as in the time of the Roswell incident (1947) [The Unnatural]. [Season 2, 3, 4, 5, 6, 7, 8]

An alien hybrid who pretended to be Mulder's sister to gain his protection. Killed by the Pilot [End Game], but she came back. In "Redux II", Cigarette-Smoking Man arranges a meeting between Mulder and an adult Samantha. It's likely this one is "the real thing" but there are no guarantees. She also says CSM has told her he's her father, that he and Mrs Mulder had protected the rest of the family from this truth, and that she has children of her own. CSM seems to be a fond father - he strokes her hair and she doesn't flinch away or anything - although he has lied to her, pretending to be searching hard for Fox, while all along, of course, he has known exactly where he is. Whether he's her real father or not, that's the role he has been playing for the past few years. [Season 2, 5]
