Dax ( episode ) New evidence reopens a thirty - year - old murder case and Dax ' s previous host , Curzon , is the prime suspect . Summary . Teaser . Chief Miles O ' Brien accompanies his wife Keiko O ' Brien to Earth to visit her mother for her 100th birthday . During his absence , Jadzia Dax and Julian Bashir are studying the required repair work . When Dax decides to call it a night , Bashir offers to accompany her to her quarters and she politely refuses . As she walks down the corridor , three hooded figures approach her . One of them , Ilon Tandro , asks her to confirm that she is indeed Dax , after which the two others knock her out and carry her across the corridor . Just then , Bashir , having decided to accompany Dax back anyway , arrives and tries to rescue her , but he is unsuccessful and is knocked out as well . Act One . While Commander Sisko and Major Kira investigate an odd residual charge of the graviton generator , Bashir regains consciousness and reports the attempted kidnapping . Sisko immediately calls a full station alert and they attempt to contain them , noting that they need one of the faster ships . The kidnappers manage to escape by avoiding Odo ' s security system and disabling the tractor beam , the cause of the earlier residual charge . However , Sisko gets it back on line in time to tow the ship back to the station . When the kidnappers emerge from the airlock , Ilon Tandro identifies himself and claims that he has a valid warrant for Dax ' s arrest . The charges are treason and murder of his father , Ardelon Tandro . Act Two . In order to stall for time , Sisko sends a message to Klaestron IV to confirm the warrant . Odo confirms the nature of the warrant , and that the crime was committed 30 years ago . Realizing it must have been Curzon Dax , Sisko is confused as he never mentioned being on that planet . Moreover , Jadzia refuses to reveal anything about the incident to Sisko , and blatantly says she does not expect help . In Sisko ' s office , Tandro wishes to be on his way , now that the warrant is confirmed . However , Sisko refuses , claiming that while the Klaestrons have an extradition treaty with the Federation , it is a Bajoran station and they have no such treaty with Bajor . Moreover , Ilon knew very well that the Bajorans would object to any request for extradition , which is why he tried to kidnap Dax . Ilon blandly says there are no Bajoran interests concerned , but Kira Nerys speaks up and says that since Klaestron IV is allied with the Cardassians , Ilon must have obtained the station ' s security codes from them – " " which not only compromises Bajoran security , but also . . . " annoys " us . " " Caught between Sisko and Kira , Ilon has no choice but to agree to an extradition hearing before Dax can be lawfully released . Odo blackmail s Quark into lending his bar for the hearing over the fact that it is not up to current building codes from the Bajoran Provisional Government . Arbiter Els Renora opens the hearing in Quark ' s with a very strict , no - nonsense call to order . Ilon simply restates the warrant , but Sisko ' s first argument is that Jadzia Dax is not the person named in the warrant . Curzon Dax should be charged , and he is dead . Renora agrees that Tandro must prove that Jadzia Dax and Curzon Dax are the same person . Sisko is pleased with himself , but Jadzia doesn ' t seem to return his look . Act Three . Sisko orders Bashir and Kira to get to work on gathering evidence that Jadzia and Curzon are different people , medical evidence and judicial precedents , respectively . In the meantime , Sisko has sent Odo to Klaestron IV to investigate the evidence on the ground . It appears that the general and Curzon were friends , an odd situation for treason . By speaking with Ilon ' s mother , Enina Tandro , Odo discovers that the charges are based on the fact that , during a civil war , a coded message informed the opposing side of his father ' s location . Of the people who knew the location , Curzon was the only one without an alibi . Enina tells him that Ilon has become obsessed with finding the one who betrayed his father , and will not be satisfied until someone is punished . Tandro ' s murder inspired his people to victory and he has since become a worldwide hero . However , Enina is adamant that Curzon did not betray her husband . Unfortunately , her son won ' t listen to her . Back on Deep Space 9 , the hearing continues and Dax ' s fate is still uncertain . Thanks to the testimony of another Trill , Selin Peers , about the nature of the relationship between the symbiont and the host , Sisko is able to establish that Jadzia and Curzon Dax are distinct entities , but Ilon argues that failure to punish Trill symbionts for acts committed in past life times would create a perfect crime . The debate becomes heated and Renora demands a recess . Curiously , Jadzia seems complacent about the entire situation . Act Four . Julian Bashir takes the stand to explain the biological connection and interdependence between the symbiont and the host of a Trill . He insists that the two individuals are very different , eventually citing that their brain waves are unique . However , upon questioning from Tandro , is forced to admit that , if the symbiont ' s brain could be isolated , there is no evidence of a change in its activity when it changes hosts . Defeated , he sits down . Sisko himself then takes the stand and talks about his long - lasting friendship with Curzon Dax and his " new friend " Jadzia . He points out Curzon ' s mentoring role , but his less - than - ideal habits . He also says that he doesn ' t know Jadzia that well , yet . Ilon interjects to say that , as a Starfleet officer , he must agree that crimes need to have punishment . The Arbiter calls for a recess before Dax is to take the stand . Soon afterwards , Sisko receives a message from Odo during a recess that he has discovered evidence of an affair between Dax and Enina , giving Dax a motive for the murder . Act Five . Odo goes back to Enina , who admits the affair to Odo ; when he asks how her husband reacted , she replies cryptically that her husband was not the hero in life that he became in death . She tells him that Ardelon will always be remembered as a hero , and that it is her place to never remarry and be the brave widow , representing him . However , faced with the situation , she decides it is time for her place in history to change . Meanwhile , Sisko confronts Dax with the new knowledge . She doesn ' t deny it , but still won ' t go into it , and won ' t defend herself with the revealed truth . She feels the shame of Curzon ' s indiscretion , just like any Trill symbiont always feels the guilt of past crimes . Sisko is again frustrated , but promises to continue protecting one of his officers , even though his arguments are running out . When the hearing resumes , Sisko establishes Jadzia ' s academic and psychological testing , though Ilon counters that she accepted the responsibility of joining with a symbiont , including past crimes . Just then , Enina enters the courtroom , much to Ilon ' s shock . Enina tells the court that when the murder occurred , Curzon Dax was in her bed , and could not have committed it . The arbiter tells Ilon he may want to re - examine his evidence and leaves . The question of whether a Trill is responsible for the crimes of its past hosts is now left unanswered . Enina turns to Ilon , but he recoils from her touch . After the hearing is over , Jadzia and Enina walk together along the Promenade . Jadzia says that there is much of Curzon that is still part of her , including the desire to protect the reputation of Dax ' s old friend , General Tandro . Sadly , Enina supposes that the truth will remain unknown forever – that it was General Tandro himself who sent the coded message , attempting to betray his own people , and that the rebels killed him for the favor . Enina bids an affectionate goodbye to Jadzia , telling her to live her life to the fullest . Memorable quotes . " " You Klaestrons are allies of the Cardassians ; your knowledge of the station confirms that they must have given you the layouts . Which not only compromises Bajoran security , but also . . . " annoys " us . " " " " I am one hundred years old . I do not have time to squander listening to superfluous language . In short , I intend to be in here until supper , not senility . " " " " It ' s all nonsense , constable ! I ' m telling you , I knew the man . " " " " But did you know the symbiont " inside " the man ? " " " " I want you to find all the medical evidence you can to support the theory that Jadzia Dax and Curzon Dax are two entirely separate people .

" " " " Is a Trill responsible for the conduct – for the acts – of its antecedent selves . " " " " Right , that kind of thing . " " " " What if I find out the answer ' s yes ?
