<P> In Milagro, the eighteenth episode of the sixth season, Agent Scully's vulnerability is exposed . In this episode, the murderer takes the victim's heart out . The suspect, a writer named Phillip Padgett, has a particular interest in Scully and is fascinated by her beauty and personality . When she goes to a church to observe a painting, the writer is there and talks to her about the Sacred Heart of Jesus . During the conversation he says she visits the church because she likes art, but not as place of worship . Scully doesn't say otherwise and later she says to Agent Mulder the writer told her her life story . All this suggests that Scully isn't a devout Roman Catholic, although she attempted to approach again the Catholic community and the Catholic faith to which she was devout in her youth, after handling the strange case presented in "Revelations" and also after dealing with life - threatening cancer during the fourth season . </P> <P> While in medical school, she carried on an affair with her married instructor, Dr. Daniel Waterston who may have been the "college boyfriend" mentioned in "Trust No 1". It is never indicated in the show whether or not the relationship became sexual . According to Anderson in the episode's audio commentary, Scully came very close to having an affair with the married Waterston but left before she could break up his marriage . The end of her relationship with Waterston came about following her decision to go into the FBI . After her entrance to the FBI's Academy at Quantico, Scully began a year - long relationship with her Academy instructor, Jack Willis, with whom she shared a birthday . </P> <P> Towards the end of the series, her previously platonic friendship with partner Fox Mulder developed into a romantic relationship . When Mulder was injured in a boat crash, he awakened in a hospital and told Scully that he loved her . In the season six episode "How the Ghosts Stole Christmas", a ghost that seems to know the inner workings of Scully's mind suggests that her source of intimacy for Mulder comes from her desire to always prove him wrong . By the end of the sixth season, Mulder and Scully were increasingly shown enjoying more light - hearted activities together, such as practicing baseball, using FBI funds for a "night out" during a movie premiere, and watching a movie at Mulder's apartment . In the season seven episode "all things", Scully is shown getting dressed in Mulder's bathroom, while Mulder sleeps, apparently naked, in the bedroom . In "Trust No 1" a man reveals to Scully that he works for a "new" Syndicate like - organization, and his job requires him and a few other colleagues to spy on her around the clock . Due to this he knows intimate details of Scully's personal life, right down to her "natural hair color" (Titian, as later confirmed by Chris Carter). It is suggested by this man that Scully ultimately initiated a sexual relationship with Mulder, as he remarked that he was very surprised when she invited Mulder "into her bed". The last scene of the series finale featured Mulder and Scully holding each other on a bed, facing an uncertain future together in love . </P> <P> In the film, The X-Files: I Want to Believe, which takes place six years later, Mulder and Scully are still in a relationship . Scully was concerned that Mulder's continuing pursuit of the unknown was taking its toll on their relationship and they could not be together if he couldn't "escape the darkness". However, the film ends with the couple sharing a passionate kiss, and in the "secret ending" after the majority of the credits, a happily smiling Scully is seen in a small rowboat with Mulder, both clad in swimwear, in a tropical sea, having taken him up on his offer to run away together . In the tenth season it is revealed that Scully and Mulder are no longer a couple, as she chose to leave him . </P>
