Fox Mulder/Relationships

===Family===
====Father====
Main articles: William Mulder and 
In early 1961, the Cigarette Smoking Man had an affair with Teena Mulder, and would father Fox 
Although the CSM kept a close eye on Mulder over the years, Fox was raised to believe his father was William Mulder. His mother never told him his true parentage and would lie when confronted about the truth 
: For Fox Mulder's relationship with the Cigarette Smoking Man, see his section below.
====Mother====
====Half-Sister====
Years after his sister disappeared, Mulder was continuing to search for her in the belief that she was still alive 
 During deep hypnotic regression conducted by Doctor Heitz Werber in 1989, Mulder was apparently able to access repressed memories of his sister's abduction. He supposedly recalled a bright light outside and a presence in the room. However, he apparently remembered that he had been paralyzed and unable to respond to his sister's repeated calls for help. 
:Mulder told Scully that he had undergone hypnosis in "Pilot". She later listened to recordings of his regression in "Conduit" and watched a video of the process in "Closure".
:Some of Mulder's supposedly recovered memories contradict the version of events seen in "", as writers and wrote that episode without having seen "". For more information, see "Questionable Information" below.
Mulder discovered the X-Files in late 1990 His investigations into the paranormal phenomenon reported in the files were fueled by his belief that his sister had been abducted by aliens. 
In 1993, Agent Scully suspected that the supposed abduction of Mulder's sister had influenced him to request an assignment involving the abduction of a female teenager who had a young brother. After the teenager was located and the agents' investigation ended, Scully listened to an audio tape of one of Mulder's hypnosis sessions while he sat alone in a church and cried over a picture of his sister. 
In 2000, Special Agent Lewis Schoniger believed that Mulder's memories were actually a typical alien abduction fantasy compensating for the sense of guilt or fear that was preventing him from remembering the truth. The FBI expert explained that Mulder's delusion played into his unconscious hope that his sister was still alive, providing him with a reason to pursue her.
With the help of police psychic Harold Piller, Mulder eventually discovered his sister's fate in 2000. After her abduction, Samantha had lived on April Air Force Base in California, apparently with and his father,C.G.B. Spender. According to a diary that Mulder found on April Base, doctors had conducted brutal experiments on her in 1979, when she was fourteen years old. Samantha could vaguely recall an older brother but seemed to think that the doctors performing tests on her had stolen her memories. Mulder noted that in her final entry, she expressed an intense desire to run away.
He found a sergeant's blotter that confirmed that Samantha had escaped from the hospital where she had been held hostage and had been picked up by police as a runaway. She had then been taken to Dominic Savio Memorial Hospital, where she had seemed to be exhibiting signs of paranoia and had given no name to the police or nurses, explaining why Mulder had found it so hard to learn what had happened to her. The hospital medical staff had found scars on her knees, wrists and chest that they had considered to be the result of self-inflicted abuse. Samantha had allowed no-one except an ER nurse named Arbutus Ray to touch her. As Samantha slept, Nurse Ray had seen a brief vision of Samantha dead in her bed, but the vision quickly passed and Samantha was unharmed. Late that night, a group of men arrived to take Samantha, but Nurse Ray found that she had disappeared from a locked hospital room, never to be seen again.
 When Mulder visited Ray's home with Scully and Harold Piller in 2000, he apparently met with an apparition of his sister and accepted Piller's theory that Samantha was with "walk-ins", old souls lurking in starlight who protect other souls from violent fates that are not meant to be. 
By 2000, the Mulder family cemetery marker in Raleigh, North Carolina, was labeled with Samantha Mulder's name. The dates of her short lifespan were noted as "1965 - 1979". 
In 2002, Jeffrey Spender confirmed that Mulder had indeed witnessed his sister being abducted by aliens. However, she had been returned and was sent to California where she and Spender had been raised together. She was taken many more times and suffered horrible tests, eventually dying in 1987. 
====Half-Brother====
It has been suggested that Jeffrey Spender is Mulder's half-brother , sharing as a biological father . This is seen when CSM writes a letter, signed "Your Loving Father", and places it in a red envelope. The red envelope is later seen delivered to Jeffrey Spender and then seen again with CSM labeled "Return to Sender".
Jeffrey Spender and Young CSM are also played by the same actor: Chris Owens.
====Wife====
see below under Romantic Interests
:There is some indirect evidence that Mulder may once have been married, but this is never explicitly proven.
====Children====
It has been suggested that Mulder is the biological father of Scully's child, William, whom she named in honor of Mulder's father Whatever the case, Mulder considers William to be his son. .
When was asked about William's origin at New York Comic-Con 2008, the executive producer confirmed that William's father was indeed Mulder.
====Grandfather====
In 1995, Mulder incorrectly recalled that his grandfather would take Munchausen by Proxy Syndrome for his stomach. 
In 2000, Mulder commented that Kuru, a disease that New Guinea tribesmen get from eating the brains of their relatives, seemed even more disgusting than when his "grandpa" used to slurp up soup. 
====Uncle====
Mulder's uncle was an amateur magician. 
:This may or may not be true. In "Humbug", after Scully performs an old sleight of hand her uncle - an amateur magician - once taught her, Mulder performs a similar sleight of hand for her and tells her, "Everybody's uncle is an amateur magician". However, Mulder may have been joking at the time.
===Romantic Interests===
====Phoebe Green====
====Diana Fowley====
=====Possible Wife=====
In 1990, Mulder wore a wedding ring, implying marriage for many fans Mulder was seen without a wedding ring in 1989 ("Unusual Suspects and 1992 (". Many fans speculated that his wife might have been Diana Fowley, as they had a relationship around this time. However, the decision for Mulder to wear the ring was David Duchovny's, as he had recently married and was "fooling around", wanting to wear it. This slight inconsistency with Mulder's character has never been addressed in the show.
====Dana Scully====
Mulder's FBI partner on the X-Files unit for several years. In 2000 the two developed a romantic relationship and had a child together, William. In 2002, after receiving the death penalty in a criminal trial, Mulder flees, and Dana Scully accompanies him In 2008 it is shown them living together as well as leaving in a boat going to a tropical island. (The X-Files: I Want to Believe) However the relationship did not last and they separated a few years later, but remained amicable.

====Dana Scully====
On March 6, 1992, Special Agent Dana Scully was assigned to work with Mulder on the X-Files and the two agents met later that day. Mulder was already aware that Scully was a medical doctor who taught at the FBI Academy and had done her undergraduate degree in Physics. He had read - and liked - her senior thesis, "Einstein's Twin Paradox: A New Interpretation". Though Mulder believed that Scully had been sent to spy on him, she ensured him that she was not part of any agenda However, Scully was unaware that she had indeed been sent to spy on Mulder because the FBI distrusted his methods. 
Nevertheless, Scully remained Agent Mulder's partner for many years. As they investigated the X-Files together, Scully gradually came to believe in his theories; in the existence of extraterrestrial life and in a conspiracy inside the government to keep their existence a secret. 
Scully once told her best friend, Ellen, that Mulder was "cute". In early 1993, Ellen asked Scully if she would ever consider dating Mulder. Scully replied that he was "a jerk", but quickly denied that he was and stated instead that he was obsessed with his work. 
In early 1994, Mulder was concerned for Scully after the death of her father. He urged her not to believe criminal Luther Lee Boggs' claim of psychic ability, convinced that Boggs was trying to mislead her. 
:The first known example of Mulder using Scully's first name to talk with her is in "Beyond the Sea", although he could have previously done so off-screen.
After the close of the X-Files in 1994, Mulder and Scully would occasionally meet. Mulder's sign that he wanted to speak to Scully was using his pseudonym, George Hale Scully's sign to Mulder that she wanted to speak to him was turning over a picture on his desk of his sister, Samantha. 
In 1994, Mulder left Washington, D.C. without informing Scully. She searched for him, learning his computer password ("TRUST NO1") along the way, and eventually found him in Puerto Rico. 
When Scully was abducted in 1994, Mulder desperately searched for her Although he returned to investigating the X-Files, Mulder's hope that his former FBI partner would be returned continued to be unrelenting. Shortly after she was discovered alive but in deteriorating health, her mother, Margaret Scully, commented that Mulder's relationship with Scully had been built on trust Scully recovered and returned to working with Mulder, although she was later diagnosed with cancer Mulder investigated her cancer and other complications related to her abduction, such as the discovery of her daughter, Emily Sim. 
By early 1995, Mulder had given Scully a key to his apartment. 
In 1996, Mulder's observation that she had lost some weight pleased Scully In the same year, the two agents held hands after helping to catch killer Robert Patrick Modell Also in 1996, Scully was exposed to an altered television signal that made her paranoid and caused her to believe that Mulder was part of the Syndicate working against them. She almost shot Mulder but he and Scully's mother managed to persuade her not to. 
Mulder and Scully's relationship continued to progress. When Scully was diagnosed with cancer, Mulder began an obsessive quest to cure her. He eventually found a cure with the help of CSM. 
When Mulder got caught in the Bermuda Triangle he kissed a woman who appeared to be Scully since he feared he may never see the real Scully ever again. When he returned to real time he told the real Scully he loved her. 
Later that year Mulder switched bodies with Morris Fletcher Mulder would talk about Scully in his sleep. When Scully realized that Mulder had switched bodies with Morris, she said: "I'd kiss you if you weren't so damn ugly."
In late 1998 or early 1999, Mulder and Scully went undercover as a married couple. Mulder thought Scully just wanted to play house. 
Later that year Mulder became ill when coming in contact with a rubbing from a spacecraft. Subsequently, he was kidnapped by CSM and his colleagues and tested on. Scully ultimately rescued him. Mulder told her that he had experienced a vivid dream, like an alternate reality in which one thing remained the same: "You were my friend". 
On New Years 2000 Mulder kissed Scully . It was implied that the two slept together later that year. 
In late 2000 Mulder and Scully went back to Oregon, the place of their first case. Mulder told Scully he wanted her to stop following him on his quest because of all she lost, like her ability to have children. After Mulder's abduction, Scully learned she was pregnant. 
Scully searched furiously for Mulder. It was revealed through flashbacks that Scully had tried in-vitro as a way to have a child, and asked Mulder to be the father After Mulder's return, he felt out of place due to Scully's pregnancy and her new partner, However the two still remained close. He gave her a doll he found at his mothers house and assisted her at Lamaze classes After the birth of their son, William Mulder kissed Scully, telling her they were both afraid of "the truth we both know. 
Mulder went into hiding to protect Scully and William. He emailed her at least once, telling her he wanted to come home to her and their son By 2002 he and Scully were very much a couple By 2008 they shared an old farmhouse and Scully revealed to Mulder that his stubbornness is one of the reasons she fell in love with him They split up a few later and reunited in 2016 when Tad O'Malley compelled to re-open the X-Files unit. 
====Walter Skinner====
====Darius Michaud====
====Jeffrey Spender====
====Alvin Kersh====
====John Doggett====
In the 8th season, Special Agent is assigned to replace Mulder on the X-Files with Scully. When Mulder first meets Agent Doggett in the Episode Three Words, he reacts negatively and shoves Agent Doggett back down in his seat in Assistant Director Skinner's office, accusing him of trying to, "...Bury the Truth."
===Informants===
Mulder has had several informants over time. and an unknown person called "Danny" have been two of Mulder's main sources of information. When he first began working on the X-Files, began providing Mulder with information. When Deep Throat was killed, took his place. , a Special Representative of the UN Secretary General, replaced X after his death.
====The Lone Gunmen====
====Danny====
====Senator Richard Matheson====
 During their first investigation together, Mulder told Scully that the only reason he had been permitted to continue working on the X-Files was that he had made connections in Congress. 
One of these "connections" was with Senator Richard Matheson, who, because he had an interest in Earth's first contact with an extraterrestrial life-form, supported Mulder's work on the X-Files at great risk to his own reputation. When the X-Files were closed down in 1994, Mulder realized that there was nothing the Senator could do to prevent that from happening, due to his reputation being in jeopardy.
Shortly thereafter, Mulder was given the opportunity to reveal his realization to the Senator, after he was taken to Matheson's office. At first, Matheson quizzed Mulder on his knowledge of Bach's , the first selection of music on the Voyager spacecraft, but learned that the FBI Agent was not as aware of the composition's importance as he himself was.
Mulder suspected that he had disappointed Matheson, due to the termination of his work on the X-Files, and discovered that Matheson feared the threat of audio surveillance being conducted on his own office. By lowering his voice while loudly playing a recording of Bach, the Senator instructed Mulder to journey to Puerto Rico's Arecibo Ionospheric Observatory in order to determine whether the radio telescope had received any transmissions from an extraterrestrial intelligence.
Matheson provided Mulder with a printed transmission from the radio telescope and ensured Mulder that he would attempt to delay the Blue Beret UFO Retrieval Team while the FBI Agent was investigating the transmission, even though he revealed to Mulder that he would only be able to postpone the team for about twenty-four hours. The Senator's information seemed to be accurate, as Mulder was chased away from the radio telescope by a deployment of armed soldiers the following day. 
====Deep Throat====
Deep Throat was an enigmatic ally of Mulder who provided answers from time to time about alien activity or other strange activity such as the dangerous AI in "" or the Lichfield experiments in "Eve."? Deep Throat eventually was murdered when he exchanged Mulder's life for the secrets Mulder and Scully had obtained ("The Erlenmeyer Flask”).
====X====
After the X-Files were closed in 1994, Mulder answered a phone call from a man who told him that he had "a friend at the FBI". When Mulder asked the anonymous caller to identify themselves, the man ended the call.
Earlier, Mulder had told Agent Scully that he was considering leaving the FBI. He was convinced that Scully had since spoken to someone in an attempt to launch a campaign to help him and that that person had been the anonymous caller. However, when Mulder approached Scully with this belief, she assured him that she hadn't spoken to anyone about the issue.
Scully later notified Mulder that someone had shoved a magazine under her door that had helped her identify a victim. The same person who had called Mulder before had supplied Scully with the magazine, a fact that Scully realized and reported to Mulder.
Shortly thereafter, Mulder struggled to catch a human who he believed was a giant flukeworm and who looked like such a creature due to exposure to high levels of radiation. Mulder's mysterious contact phoned him again and told him that the success of his current assignment was imperative because reinstatement of the X-Files had to be undeniable. 
====Marita Covarrubias====
Marita Covarrubias, a Special Representative to the Secretary General of the United Nations, provided Mulder with information on several occasions in 1996. Mulder was led to find her after X, in his dying moments, left a message written in blood outside Mulder's apartment.
On their first meeting, Covarrubias apologized to Mulder that an investigation into a Canadian farmland had not uncovered the answers he had hoped for. She was also curious as to why the matter was so important to him, as he had not told her that he had found a colony of clones that looked like his sister there. When Mulder awkwardly replied that he had "recently" suffered some very personal losses, Marita stated, "not everything dies". Mulder, who had recently been told that "everything dies" by an alien bounty hunter, started to wonder about her allegiances. 
In August 1996, Mulder came to Marita Covarrubias and told her about a case he was working on. She seemed reluctant to speak with Mulder, claiming to have no knowledge of the case and declaring that she was unable to help him. Mulder suspected that she knew more about the case than she claimed to know but was unwilling to aid him. 
The Syndicate was secretly paying Covarrubias for the use of her diplomatic power in furthering their goal to develop an alien virus vaccine before the Russians could, an arrangement that Mulder had no knowledge of. Marita Covarrubias eventually came to hate the Syndicate and consequently chose to co-operate with Mulder as he worked on the X-Files She also helped Mulder because she could and because she believed in him and in his search for the truth 
On November 25, 1996, Mulder went to Marita's apartment at 12:36 pm. She slightly opened her door to him but opted to use a security chain that barred the entrance. When she asked why he had come to her home, Mulder made it clear that he needed her help. He apologized for bothering her but claimed that it was a matter of extreme urgency. Mulder explained that two men had died in relation to a diplomatic pouch which had left Russia and arrived in the United States and wanted to know the reason they had died. Marita finally unchained her door and allowed Mulder into her apartment.
Nearly four hours later, Mulder was sleeping on a chair in her living room while Marita, dressed in her nightgown in another room, made a phone call. After ending the call, she walked into her living room and knelt down beside Mulder. She relayed news to him that the diplomatic pouch had traveled an apex route to the Russian city of Norilsk, in the province of Krasnoyarsk. Mulder started to look for his cell phone to book himself a flight to Krasnoyarsk. When Marita offered to help him, Mulder initially thought she intended to help find his phone. She clarified that she could provide him with cover details, such as a visa and a diplomatic passport. Three minutes later, Mulder had left her apartment with the cover details she gave him. 
When Marita was next contacted by Mulder, he told her he needed information on American prisoners of war. They met in the Lincoln Memorial, where Mulder explained that a POW named Nathaniel Teager may have returned from Vietnam and could be killing the men who had left him there. Although Mulder already knew the names of two of those men, Marita informed him that there was a third man but would not reveal his name. 
By April 27, 1997, Mulder had a record of Marita's contact details that he kept in his office at FBI Headquarters. Marita later called the Cigarette-Smoking Man, who instructed her to tell Mulder what he wanted to hear. 
In early 1998, Marita discovered that Mulder had been at , where several burned bodies had recently been found.
After betraying the Syndicate, Covarrubias called Mulder from a pay phone. She checked that they were speaking on a secure line before revealing that she had been in the former Soviet Union, where an incident similar to the one on Skyland Mountain had occurred. Covarrubias also informed Mulder that she was with someone, a Russian boy infected with the alien virus, who knew that both incidents were connected. She told Mulder where she was, instructed him to go to the same phone booth and to wait for her to call with more directions. Suddenly, however, Marita dropped the phone in shock, abruptly ending her conversation with Mulder. 
When Mulder next saw Covarrubias, she was running through a deserted corridor at Fort Marlene Decontamination Center in early 1999. Marita momentarily stopped to look at him before quickly continuing on her way. Mulder ran through the corridor in pursuit of Covarrubias and eventually found her hiding in a laboratory. She looked poorly and warned Mulder that the Syndicate would kill her if they were found together.
Marita revealed that the Syndicate was cooperating with a race of aliens that planned to colonize Earth, but were secretly attempting to create a biological weapon to use against the aliens. She claimed that the Syndicate had conducted terrible tests on her as part of their attempt and explained that Cassandra Spender was part of a long-standing program in cooperation with the aliens to create an alien/human hybrid. Mulder suspected that Cassandra Spender was the result of the hybrid program and that she was the first successful alien/human hybrid. Marita warned that if Mulder's suspicion was accurate and the aliens discovered that a hybrid existed, they would begin relentlessly colonizing the planet. 
In 2000, Marita went with Alex Krycek to visit Mulder in his office. They told him that the Cigarette-Smoking Man was dying and explained that his last wish was for Krycek and Covarrubias to find a downed alien craft that Mulder had been looking for and revive the conspiracy.
Mulder and Marita then visited the Lone Gunmen with Scully, Krycek and Skinner. As the Gunmen discussed detection methods to find the UFO, Mulder and the others learned from Marita that the ship was rebuilding itself. 
In May 2002, Marita defended Mulder at his trial. Although she was initially chosen as his central witness, Marita could not be found and other witnesses were therefore called. In his cell, Mulder was visited by a vision of X, who handed him a note of Marita's address.
After she was eventually found, Marita admitted at Mulder's trial that her hatred of the Syndicate had motivated her to help him. Mulder and other men present at his trial learned that Marita had resisted testifying before the tribunal because the conspiracy continued, only conducted by others. Skinner urged her to prove that the man Mulder had apparently killed, an alien replacement referred to as a super-soldier, was one of the new conspirators. Mulder realized that the conspirators would kill Marita if she admitted that they existed. Mulder consequently insisted that Skinner dismiss Covarrubias. Although Skinner believed that Marita was Mulder's "last best witness", he eventually complied with his client's wishes. Marita looked to Mulder for the first time at the trial and slightly nodded her head in thanks. Mulder returned the gesture before Covarrubias left the room.

====Cigarette Smoking Man====
After visiting the Mulder family in the 1960s, the CSM would fondly remember young Fox and Samantha playing. 
In October 1973, the CSM visited the Mulder household and may have had a role in choosing Samantha to be abducted. Fox remembered this situation in 1997 while suffering several hallucinations. 
In March 1994, Mulder didn't recognize the CSM in Skinner's office when he was reprimanded by Skinner for possibly abusing Eugene Victor Tooms in an X-file case. 
In July 1994, the CSM wiretapped Mulder's phone in an attempt to send Mulder on probation and out of the FBI. His attempt failed when Mulder told AD Skinner about the wiretapping. 
In August 1994, Mulder was present at two meetings with the CSM involving Agent Scully's disappearance and the death of Duane Barry. He began to suspect that his partner, Alex Krycek, was working with the CSM after discovering cigarette butts in Krycek's car. 
In November 1994, shortly after Scully's return, Mulder discovered where the CSM lived. Mulder appeared at the CSM's apartment on 900 W. Georgia Street and attempted to threaten him for information. Mulder failed and, in his disgust, nearly resigned from the FBI. 
In March 1995, Mulder had a conversation with the CSM in Skinner's office in which the CSM informed Mulder that the truth sometimes needs to be hidden from the public in order to protect them. 
In April 1995, Mulder came into possession of a top secret MJ document which was being searched for by the CSM and Garnet operatives. The CSM desperately searched for Mulder and nearly killed him when lighting an old refrigeration car on fire. 
In November 1995, while searching through silos for a missing UFO, Mulder was discovered by the CSM and taken back to Washington when it was discovered that he knew nothing. 
In the summer of 1996, the CSM was threatened once again by Mulder when visiting Mulder's mother in hospital. 
Shortly thereafter, Mulder was told a possible history of the CSM after the Lone Gunmen pieced together information from two publications, 1968's Take a Chance: A Jack Colquitt Adventure and 1996's Second Chance: A Jack Colquitt Adventure, which the Lone Gunmen believed had been written by the CSM. 
In October 1997, the CSM allowed Mulder to gain the cure for Scully's cancer from the Advanced Research Project Facility in the Pentagon. He later visited Mulder and helped explain how the cure worked by inserting a microchip in Scully's neck. The CSM later brought a person who he claimed to be Samantha Mulder to meet with Fox at a restaurant. The next day, the CSM attempted to persuade Mulder to work for him, but Mulder turned the offer down. Mulder later believed that the CSM had died after much of his blood was found in his apartment. 
In May 1998, Mulder was discovered that the CSM was alive and seemingly working with Jeffrey Spender. 
In August 1998, the CSM was quite perplexed when he discovered Mulder in Antarctica, and even more confused when he discovered that Mulder had the Purity vaccine. ()
In early 1999, the CSM had a conversation with Mulder when he found him searching Diana Fowley's apartment. The CSM told Mulder of the events involving his father in 1973, and informed Mulder of the location where the colonization was to begin. 
In October 1999, after being exposed to an alien artifact, Mulder became an alien/human hybrid. When the CSM put him to sleep to work on extracting his alien genetic material, Mulder entered a dream state where he had several conversations with the CSM, and ultimately ended up living in the same neighborhood as he was while alien colonization that Mulder had apparently caused took place outside. 
In May 2002, the CSM secretly sent Mulder the key to the Mount Weather Complex. With this key, Mulder learned of the date set for the colonization. When Mulder once again set eyes on the CSM, he at first believed him to be a ghost.
