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.
