Jadzia Dax Jadzia Dax was a joined Trill and the eighth host of the from 2367 to 2374 . She was a Starfleet science officer who served on space station Deep Space 9 under the command of Captain Benjamin Sisko . Early life and career . Jadzia was born in 2341 , on stardate 23634 . 1 , on , where she grew up with her her mother , father and a sister . Although Jadzia was always a shy and quiet child , she was very driven by her ambitions to one day be joined to a symbiont . She spent much of her early life focusing on achieving her goals and would become the only member of her family to be joined . ( ) Prior to her joining , Jadzia attended Starfleet Academy and applied to the Trill Symbiosis Commission for joining after graduation . While at the Academy , she earned Premier Distinctions in astrophysics , exoarchaeology , exobiology and zoology . ( ) After working hard , Jadzia was initially rejected for joining and eliminated from the program by her field docent Curzon Dax in 2364 . The reason he gave for this decision was that Jadzia lacked purpose . After Curzon ' s initial decision , she successfully re - applied that same year and became the only Trill in history to successfully complete the program after having been rejected . She described herself as going as a " " different woman " " into the program and " " tore through it with a passion " " . The experience of her initial rejection would haunt her for years to come and was one reason why she never had positive feelings about returning to Trill . She never could understand why she was washed out of the program by Curzon . ( ) She was joined to Dax in 2367 after the death of Curzon . After being approved for joining , she had heard of Curzon ' s deteriorating health and requested that she receive the Dax symbiont after Curzon ' s death . Later , during her " zhian ' tara " , she learned that Curzon ' s reasons for rejecting her original application were personal , since he had actually fallen in love with her . ( ) After being joined to Dax , Jadzia ' s training and experiences made the adjustment to having seven different lifetimes of memories and experiences relatively easy . The once shy , hardworking and dedicated Jadzia became a lively , confident and outgoing person with a passion for life . Jadzia was very comfortable with who she was . She was later described by Garak as " " vital , alive . . . she owned herself . " " ( ) After joining , Jadzia picked up on the habits of her previous hosts , such as clasping her hands behind her back , taking up Klingon martial arts , an interest in Klingon culture or playing tongo . ( ) Even as an ensign and lieutenant jg in Starfleet , she had dealings with many prominent officer s . She was acquainted with Captain Keogh , though the two did not get along . She was also friends with Captain Shelby , who even owed her a favor , which Jadzia eventually cashed in . ( ) Aboard Deep Space 9 . In 2369 , twenty - eight - year - old Lieutenant Jadzia Dax was assigned as science officer aboard Deep Space 9 , under the command of Benjamin Sisko , who had been a friend of Curzon . Shortly after her assignment to the station , Jadzia and Sisko discovered the Bajoran wormhole , opening a new era in Federation history . ( ) Later that year Jadzia stood trial for crime s that Curzon had allegedly committed during the Klaestron Civil War . Though she was ultimately cleared of the charges , Jadzia had been willing to accept a guilty verdict in order to protect the honor of Curzon and Enina Tandro . ( ) She became a real - life game piece in a game of Chula , a Wadi game that Quark was forced to play . ( ) An alien took her form and became very amorous with Julian Bashir . ( ) In 2370 , the Dax symbiont was removed from Jadzia and kidnapped by an unjoined Trill , Verad , who believed he had been cheated of being joined . He was briefly joined with the Dax symbiont , becoming Verad Dax before he was apprehended and Dax was rejoined with Jadzia . After she was rejoined with the symbiont , Verad ' s memories – cold and afraid – stayed with her for the rest of her life . ( ) After landing on a planet in the Gamma Quadrant , Jadzia and Odo tried to solve a mystery . The people of the village were disappearing . They discovered that the people were hologram s , created by Rurigan , whose village was wiped out by the Jem ' Hadar . The hologenerator was malfunctioning , but they were able to fix it and bring the people back . ( ) That same year , Jadzia took on the role that had caused her so much pain before , that of field docent for the Trill Symbiosis Commission . Her initiate , Arjin , boarded Deep Space 9 with a great deal of apprehension because of the legendary harshness of Dax as a field docent . Jadzia , however , was determined not to be the same kind of docent that Curzon had been and made every effort to convince Arjin of this . ( ) Jadzia kept an oath made by Curzon with his Klingon brothers . His friends ' sons had been killed by the Albino , a master criminal , against whom the four vowed vengeance . At first , they were reluctant to accept her into their group , but she successfully persuaded them . She participated in the attack that killed the Albino ; however , two of the three Klingons were also killed . ( ) Jadzia was threatened with the removal of Dax a second time in 2371 , when it was discovered that a previously undisclosed host , Joran Belar , had been psychotic . This previously unknown host was a skilled musician who had had a violent temper and killed people ; including the doctor who recommended that he be dropped from the program . Jadzia had unknowingly begun to manifest some of Joran ' s musical talents . The Trill Symbiosis Commission had kept the memories of Joran blocked from both symbiont and host , but they began to resurface and threatened to cause Jadzia to reject Dax . Doctor Bashir then recommended that he and Commander Sisko take Dax back to Trill for treatment from the doctors of the Symbiosis Commission as Doctor Bashir ' s knowledge of Trill biology ; specifically symbiosis , was limited . Subsequent investigations by Commander Sisko and Doctor Bashir uncovered the existence of Joran Dax . Under threat of exposing their great secret – that one in two Trill were capable of joining , not the generally believed one in ten thousand – the Commission agreed to restore Joran ' s memories by allowing the memories to completely surface and reintegrate into her mind , which ultimately equalized the symbiosis and saved Jadzia ' s life . ( ) In 2371 , she was transported back in time to the era of the Bell Riots , an event which caused social upheaval and awareness of the plight of the poor . While Sisko and Bashir were trapped in a Sanctuary District , Dax was befriended by a wealthy businessman named Christopher Brynner who took her in under the assumption that she had been mugged . Jadzia and Christopher quickly became friends . She accompanied him to a business function . Subsequently , she convinced him to allow the impoverished residents to speak out on his television network . It is worth noting that during her time in this time period , Dax was able to successfully breach the local computer systems and successfully procure legitimate identification , internet logon credentials and credit cards to better blend into the environment . Consequently , she was able to contact the crew of the , who were able to return them to their own timeline , with only a few minor changes . ( ) At some point between stardate s 48959 ( ) and 49011 ( ) , Jadzia was promoted to the rank of Lieutenant Commander . Jadzia became trapped with Bashir in a turbolift with limited air during an attack by the Jem ' Hadar on the " Defiant " . She and Julian were rescued just as the air ran out . She helped Kor and Worf retrieve the Sword of Kahless , saving it from being taken by Toral , a usurper to the leadership of the Klingon High Council . She assisted Bashir in his attempts to cure the blight , a disease caused by a bioweapon with which the Jem ' Hadar had infected a planet . ( ) Jadzia joined Worf on Martok ' s ship , the . The crew was lax and had no fighting spirit , due to the constant defeats by the Jem ' Hadar . She helped instill Klingon pride and spirit in them , which contributed to them winning their first battle . She also helped Sisko capture Michael Eddington , a former Starfleet officer on Deep Space 9 , who had joined the Maquis . ( ) Dominion War . Jadzia became an important figure during the Dominion War . With the threat of invasion , Jadzia commanded the " Defiant " in a mission to mine the Bajoran Wormhole . She was ordered to do this in order to prevent further Dominion reinforcements from coming through . Ultimately , this action was the catalyst that began the Dominion War . After Deep Space 9 was taken by the Cardassian / Dominion fleet , Jadzia piloted the " Defiant " to safety . Soon after , she became involved in several battles with the Dominion aboard the " Defiant " . During a mission to destroy a ketracel - white facility in Cardassian space , the Dax symbiont was badly injured from the explosion . Jadzia , along with the rest of her crew , was rescued soon after by the " Rotarran " . In early 2374 , Jadzia was given command of the " Defiant " by Admiral Ross , after he promoted Captain Sisko to be his adjutant . When it was uncovered that a major reason for the Dominion ' s dominance was a sensor array monitoring all activity across five sector s , Jadzia commanded a successful mission to destroy it . She was aboard the " Defiant " for Operation Return and was present for Sisko ' s near - suicide mission into the wormhole to stop Dominion reinforcements from coming through . Fortunately , the Prophet s intervened , saving Dax and the rest of the crew of the " Defiant " . ( ) Jadzia was left in command of Deep Space 9 when the Federation and allied forces went on the offensive at the First Battle of Chin ' toka . With majority of the crew away from the station , Gul Dukat ( controlled by a Pah - wraith ) was able to beam aboard with the intent of releasing a Pah - wraith into a sacred Orb in order to imprison the Prophets in the wormhole . Jadzia unsuccessfully tried to stop Dukat , and was fatally injured in the process . Her symbiont was saved and transferred to another Trill , Ezri Tigan , who became Ezri Dax . ( ) Personal interests . Jadzia was an outgoing individual with varied interests . Many of her pursuits were the result of influences from her previous hosts . Joran Dax left her with an appreciation for music , even though no one in her family had any musical ability , and after re - integrating Joran ' s personality she regularly practiced playing music herself . However , even before becoming aware of Joran , Jadzia had been a collector of the music of lost composers . ( ) Her favorite song was " All the Way . " ( ) Jadzia also enjoyed playing tongo with Quark and the other Ferengi on the station . She claimed that , while Kira was right about the Ferengi being greedy misogynistic troll s who couldn ' t be trusted , once you accept that they could be a lot of fun . ( ) Jadzia , influenced no doubt by Curzon , enjoyed fighting and loud , often raucous parties . Such behavior led Sirella , the wife of Martok to call her a Risian slut . Other experiences , such as Tobin ' s intimate knowledge of warp drive theory and his knack for magic tricks , often manifested themselves in Jadzia ' s day - to - day life as well , but with less drastic results . She also took lessons and practiced Galeo - Manada wrestling . ( ) Emony , the third Dax host , had been a professional gymnast , and it was after her joining that Jadzia developed an interest in physical exercises along those lines . These interests merged in part with Curzon ' s love of Klingon culture , and she took up Klingon calisthenics and combat techniques . Additionally , Jadzia inherited other characteristics from previous hosts , as she learned during her " zhian ' tara " . For example , Lela often paced with her hands behind her back , while Tobin bit his nails , both things Jadzia had often done subconsciously . One unique experience she found fascinating was Curzon ' s time spent merged with Odo ; this gave Jadzia a unique opportunity , allowing a solid to briefly experience what it was like to be a Changeling . ( ) Personal relationships . Friendships . Benjamin Sisko . The previous Dax host , Curzon , had been Benjamin Sisko ' s mentor during Sisko ' s younger days and the two were close for almost twenty years . When Curzon died and Jadzia became host to Dax the friendship between the two persisted and Sisko continued to call Jadzia " old man " , a term he had used affectionately with Curzon . Though it was initially difficult for him to adjust to Dax ' s new appearance , Jadzia and Sisko became friends again quickly ; indeed , it was revealed when Jadzia contracted zanthi fever due to Lwaxana Troi ' s presence that she was at least subconsciously attracted to Sisko , but once the fever was cured the two apparently silently agreed to never talk about it . ( ) During Dax ' s " zhian ' tara " , she asked Benjamin to embody Joran Dax , an insane murder er who had received the symbiont by accident . Sisko took this in good faith and voluntarily took on the role of Joran . Joran attempted to kill Jadzia but she fought Sisko off , and once he regained control he thanked her for not breaking any bone s . Dax confided in Sisko about her feelings of inadequacy when it came time for her to meet Curzon Dax via Odo . Though Sisko tried to reassure her that she was strong , she was unsure of what would happen . When Curzon decided to keep Odo ' s body , thus depriving Jadzia and the Dax symbiote of Curzon ' s experiences , Sisko revealed to Dax that , while a charming man , Curzon was also selfish , and he told her to confront Curzon so the older Trill would back down . ( ) Jadzia considered Sisko one of her closest friends , and the feeling was mutual . The two went to extremes to protect and help each other . In 2369 , when Dax was accused of murder by the Klaestron government , Sisko mounted a spirited defense on her behalf . ( ) On later occasions , when Jadzia ' s health was threatened by a rogue Trill , and by possible rejection of her symbiont , Sisko went to great lengths to make sure his friend survived . ( ) When Jadzia at one point called off her wedding to Worf , Sisko stepped forward to tell her that she was being unreasonable , and convinced her to go on with the event . ( ) Jadzia ' s death was particularly hard for Sisko to accept , coming as it did at the height of the Dominion War and in the midst of several personal crises for him . Before her funeral , and shortly before his departure from Deep Space 9 on a leave of absence , Sisko confessed to her that he needed her most now , and painfully regretted that she was gone , also mentioning that , while Curzon was his mentor , Jadzia was his friend . ( ) Kira Nerys . Kira and Dax were far from the best of friends when Dax was first stationed aboard DS9 , since Kira didn ' t trust the Federation . Despite this , their professional relationship grew friendly over time . They traded stories and teased one another ; they also gossiped about various goings - on at the station , and Kira regularly confided in Dax about her relationships with Bareil and later Shakaar Edon , even though Dax had a tendency to let things slip . ( ) When Dax was considering going with Kang , Koloth and Kor to kill the Albino , Dax wanted to confide in Kira but didn ' t want to get into the details . However Kira made Dax talk to her about it . Once Kira learned of the plan , she warned Dax that killing someone means you lose part of yourself . ( ) Although Kira believed holosuite s were a waste of time , Dax eventually convinced Kira to visit a holosuite with her . Although their initial plan to go kayaking was interrupted , Dax later took Kira to a simulation of the Hoobishan Baths on Trill and to Camelot . While in the latter program , Kira ' s lack of familiarity with the storyline led her to knock out Lancelot when he tried to kiss her , as she was playing a married woman at the time . ( ) Nerys embodied Lela Dax , a kind old woman , during Jadzia ' s " zhian ' tara " . ( ) Julian Bashir . From the very beginning Julian Bashir was infatuated with Dax and he asked her out several times shortly after their stationing aboard DS9 . Despite a lack of interest in Julian as a romantic partner , Jadzia admitted that she enjoyed being pursued by him . ( ) Much later , Ezri Dax would reach the conclusion that , if Worf had not entered her life , Jadzia would have eventually become involved with Bashir . ( ) When Julian eventually got over Jadzia , an accident that trapped them together for a time aboard the " Defiant " led him to observe how much she enjoyed being chased ; now that he had stopped , he claimed she missed it . Jadzia admitted that Bashir was quite charming , but he had come on so strongly at first that she could barely breathe . In any case , they both valued their friendship enough that they would not give it up for anything . ( ) Bashir , along with Quark , was initially upset over the marriage of Worf and Jadzia , and even more so when the two announced their intention to have children . It should be noted that Bashir ' s concerns / jealousy over Jadzia having children with Worf is most likely motivated by concerns over her health and her ability to successfully carry such a child to term as he notes how difficult it would be for a Klingon and a Trill to have a child together . Still , his desire to see her happy allowed him to overcome his jealousy . After her death , Julian ' s feelings re - surfaced when he met the new Dax host , Ezri . Ezri , stirred in part by Jadzia ' s memories of Julian , realized she was attracted to him as well and the two eventually became involved . ( ) Bashir embodied Torias Dax , a confident and outgoing man , during Dax ' s " zhian ' tara " . ( ) In an alternate timeline , she and Bashir eventually ended up together . She complained once about Bashir ' s children interrupting them and such . ( ) Quark . Jadzia and Quark , the resident Ferengi entrepreneur of Deep Space 9 , developed a long - term friendship during her years on the station . Unlike most other members of the station crew , Jadzia had an affinity for Ferengi society . She regularly joined the Ferengi staff of Quark ' s Bar for games of tongo , and often served as a sounding board for Quark when he faced particularly thorny financial , ethical , or legal issues . ( ) Though Quark did not want to participate in Jadzia ' s " zhian ' tara " at first – he was not eager to let " some dead person " inhabit his body – Jadzia convinced him otherwise . She even got him to embody Audrid Dax , a woman whose greatest joy in life was having children . During the " zhian ' tara " , Quark impatiently interrupted to make sure Jadzia would not tell anyone about the embarrassing things Audrid was saying through him . ( ) Their friendship was greatly strained when Quark briefly entered the field of weapon s sales . Jadzia made it clear to Quark that she found his new profession reprehensible and wanted nothing further to do with him . In part because of her reaction , Quark left behind his career as an arms merchant and was able to rekindle their friendship . ( ) After Jadzia ' s death , Quark was among those who participated in the mission to destroy the Monac shipyards in an effort to guarantee Jadzia ' s entrance into " Sto - vo - kor " . ( ) The crew of DS9 . Other people Jadzia felt close to included Leeta , Odo , and Miles O ' Brien . She thus invited them , along with Sisko , Bashir , and Quark , to take on the form of her previous hosts during her " zhian ' tara " ceremony . ( ) Dax took perverse pleasure in annoying Odo , who had such a specific routine that he became agitated when something in his quarters was so much as a centimeter out of place . Occasionally , Quark would distract Odo while Dax snuck into Odo ' s quarters and moved everything out of alignment – just enough that Odo would notice . She and Quark thought Odo needed to lighten up , but he did not find this amusing and eventually forced her to put everything back where it belonged , taking the same perverse pleasure in making the moving process take longer than necessary . ( ) Klingons . Jadzia , like Curzon , had the heart of a Klingon and honored a blood oath with Kor , Kang and Koloth to kill the Albino . ( ) She also became a member of the House of Martok after she married Worf . ( ) Jadzia was a skilled warrior with the Klingon " bat ' leth " , and often practiced with her weapon in the holosuites . When Worf arrived on the station , she found in him an ideal sparring partner ; he immediately gained respect for her fighting prowess , though they often had disagreements over which was superior , the " bat ' leth " or the " mek ' leth " ( Worf ' s weapon of choice ) . She made it clear that when fighting in a holosuite her opponent was not to hold back because she was a woman or a Trill . Their sparring may have directly led to their romance and marriage . ( ) In addition to speaking Klingon , Jadzia was a keen follower of many Klingon traditions . She enjoyed eating " gagh " and drinking blood wine . ( ) Like Curzon , she had a deep respect and understanding for the Klingons . ( ) Family . One of Jadzia ' s parents was named Kela . ( ) Her mother was still alive as of 2372 . Every time Jadzia went into battle , she recorded a message to her mother in case she would die . ( ) Jadzia had at least one sister who led a full and productive life without being joined , as did their parents . She sent Jadzia glassware as a gift in late 2372 . She gave them to Quark after his property was seized by the FCA . ( ) Romance . Jadzia expressed to Bashir that Trills seek to live on a higher plane and rise above physical temptations . ( ) Deral . When the " Defiant " discovered Meridian , a planet that faded in and out of existence periodically , Jadzia had a brief romantic relationship with Deral , an inhabitant of Meridian . Their attraction to each other was so strong that Deral decided to leave Meridian in order to stay with Jadzia . The decision was momentous . The planet was sparsely populated and any absence would be felt by its remaining population intensely . Deral ultimately decided he could not leave his planet and Jadzia elected to remain behind on the planet when the " Defiant " left in order to phase out of normal space along with Deral and the rest of the inhabitants . However , it was soon discovered that her presence on the planet during its shift would disrupt the delicate balance there and prevent the shift from occurring . This in turn could lead to the destruction of Meridian and everyone on it . Unable to complete the transition , Jadzia watched helplessly as Deral and the others crossed into the separate dimension for another 60 years . ( ) Kahn symbiont . At one point Jadzia faced ostracism from Trill culture when she briefly considered a relationship with Lenara Kahn , a Trill scientist from the Trill Science Ministry . The previous hosts of both symbionts , Torias Dax and Nilani Kahn , had been married , and when Kahn visited Deep Space 9 to conduct experiments on the wormhole she and Jadzia became close . In doing so Jadzia and Lenara were violating the Trill taboo against reassociation . Knowing that allowing their relationship to continue would mean being expelled from Trill society , and that their symbionts would die with them , Lenara broke off the relationship . ( ) Worf . During her first few years on Deep Space 9 , Jadzia was romanced both by Dr . Julian Bashir and Quark . Neither of them proved able to win her heart , though , and it was in 2372 Lt . Commander Worf was reassigned to the station and met Jadzia for the first time . With her impressive knowledge of Klingon history and society , Worf found her a singular companion . Jadzia gave Worf a copy of her calisthenics program , which Worf mistook for Curzon ' s program . At this , Jadzia challenged Worf to a " bat ' leth " match . She lost , but impressed Worf with her skill . ( ) When Worf moved his quarters to the " Defiant " , Jadzia gave him her collection of Klingon opera s , suggesting to play them through the " Defiant " s communication s systems . Worf accepted them as a thoughtful gift . ( ) As their friendship grew , so did their interest in each other , and ultimately the two fell in love ; they became romantically involved in early 2373 . At that time Worf was pursuing Grilka , an attractive Klingon female . However , since Mogh ' s family honor had been disgraced , Grilka could not possibly mate with Worf . Jadzia helped him deal with the disappointment by assisting him in courting Grilka through Quark . In the end though , it was Jadzia and Worf who discovered their attraction for each other . They vacationed on Risa together , and Jadzia was able to get Worf to relax and lose his sternness . ( ) In 2374 they were married and Jadzia became a member of the House of Martok , despite the initial objections of Martok ' s wife , Sirella . ( ) The marriage proved strong . When Lasaran , a Cardassian defector , contacted Starfleet Intelligence in 2374 , Worf and Jadzia were ordered to rendezvous with him and return him safely to Federation space . During the mission Jadzia was seriously wounded by a Jem ' Hadar energy weapon . The anticoagulant properties of the weapon put Jadzia ' s life in danger , and Worf abandoned Lasaran in order to save her . As a result , Lasaran died trying to re - enter the Dominion base . The action caused Worf to receive a reprimand , and Captain Sisko believed it would prevent him from ever receiving his own command , but Worf stated he had no regrets . ( ) By late 2374 , Jadzia and Worf had decided to attempt parenthood , despite the extreme difficulties posed by the disparate biologies of Trills and Klingons . With the help of Dr . Bashir , who administered ovarian resequencing enzyme s , it looked as if Jadzia would be able to conceive . In thanks , she visited the Bajoran Temple on the Promenade , where she was attacked and killed by Gul Dukat , who had been possessed by a Pah - wraith seeking the destruction of the Orb kept in the temple . ( ) In 2375 , Worf led a mission to destroy the Dominion shipyard s at Monac IV . He dedicated this mission to his late wife , in order to ease her entrance into " Sto - Vo - Kor " . ( ) Holograms . Jadzia was holographically duplicated at least twice . Appendices . Background information . Jadzia was played by Terry Farrell throughout the first six seasons of .
