Symbiosis

Jadzia Da, played by Terry Farrell, was a main character during the first six seasons of the science fiction television series Star Trek: Deep Space Nine. Jadzia Dax is a joined Trill. Though she appears to be a young woman, Jadzia lives in symbiosis with a wise and long-lived creature, known as a symbiont, named Dax. The two share a single, conscious mind, and her personality is a blending of the characteristics of both the host and the symbiont. Jadzia Dax is the station's chief science officer, and is close friends with commander Benjamin Sisko and Bajoran first officer Kira Nerys. Later in the series, she becomes involved with the Klingon character Worf, and they marry during the sixth season of the show. The character is killed off in the season six finale due to actor Terrey Farrell's desire to persue another role. -wikipedia
