"Dax" is the eighth episode of the American science fiction television series Star Trek: Deep Space Nine. Set in the 24th century, the series follows the adventures on Deep Space Nine, a space station located adjacent to a stable wormhole between the Alpha and Gamma quadrants of the Milky Way Galaxy, near the planet Bajor. This episode explores the nature of the fictional Trill species, a humanoid race some of whom are symbiotically "joined" to a long-lived "symbiont" creature, whose memories they share. The station's science officer Jadzia Dax, a Trill, is arrested for a crime of which a previous host of her symbiont is accused. This episode was co-written by D.C. Fontana, who had also written for Star Trek: The Original Series. Plot After having a meal with Dr. Bashir, Lt. Dax is abducted by a group of aliens while walking back to her quarters. Dr. Bashir alerts Commander Sisko that she has been taken, and the Deep Space Nine crew is able to prevent the abductors from leaving the station. One of the abductors, Ilon Tandro, accuses Dax—the Dax symbiont, then in the body of Curzon Dax—of murdering his father, Ardelon Tandro, a famous military hero from Klaestron IV; he wants to punish Jadzia Dax for the crime. His claim is based on the fact that during a civil war a coded message informed the opposing side of his father's location, and of the people who knew the location, Curzon was the only one without an alibi. Major Kira insists that Dax cannot be extradited to Klaestron without an arbitration hearing under Bajoran law. At the hearing, Sisko argues that Jadzia and Curzon Dax are two different individuals, sparking a lengthy debate. The arbiter suggests removing the Dax symbiont and leaving Jadzia behind, but Dr. Bashir says that neither would survive the operation. Ilon argues that failure to punish Trill symbionts for acts committed in past lifetimes would create a perfect crime. Curiously, although her fate is uncertain, Jadzia seems complacent about the entire affair. Meanwhile, DS9's security chief Odo visits Ilon's mother, Enina. She tells him that Tandro's murder inspired his people to victory, and he has since become a worldwide hero, but she is adamant that Curzon did not betray her husband. Odo discovers evidence of an affair between Curzon and Enina, giving him a motive for the murder. Enina admits the affair to Odo and
