Lenara Kahn Lenara Kahn was a female Trill who served as a scientist at the Trill Science Ministry during the late - 24th century . She was joined to the Kahn symbiont . History . At one point before 2372 , she met a Klingon scientist who gave her Klingon earring s . In 2372 , she and her colleagues , Hanor Pren and her younger brother Bejal Otner , visited Deep Space 9 to conduct field tests on a technique to create artificial wormhole s . Although initial results were promising , it was found that the wormholes were unstable . While on the station , Lenara became acquainted with Jadzia Dax . Their former host s , Torias Dax and Nilani Kahn , had been married , and they found their past feelings for each other re - emerging . After Lenara was nearly killed on the accident aboard the , Jadzia voiced her willingness to resume their previous relationship , despite the cost of reassociation . However , Lenara was unwilling to accept exile from Trill society , and the two parted company . ( ) As part of the defensive effort in the Dominion War , Kahn developed a way to seal the Bajoran wormhole without damaging it or harming the beings living within , by using a series of phase - conjugate graviton beam s . The technique was put into practice in 2373 in order to stop a Jem ' Hadar fleet from invading the Alpha Quadrant , but the attempt was sabotage d by a Changeling infiltrator disguised as Julian Bashir . The sabotaged beam in fact rendered the wormhole even more stable and resistant to collapse . ( ) Memorable quotes . " " Seems a shame to disappoint them . Maybe we should do something . " " < br > " " We could get into a screaming match and start throwing things at each other . " " < br > " " Not bad . Or I suppose we could throw ourselves at each other , profess our undying love for each other and complete disregard for Trill society . " " < br > " " Doctor Pren would probably have a heart attack . " " < br > " " Well , Torias used to be insensitive at times . But you have to admit , Nilani did do her share of overreacting . " " < br > " " That ' s because you were a pilot and it made me nervous . Made her nervous . Torias being a pilot made Nilani nervous . I ' ve never had quite this much trouble sorting out my feelings from those of a past host . " " < br > " " I know what you mean . " " < br > " " Probably another good reason why we ' re not supposed to spend much time together . We ' d probably just get lost in the past . " " < br > " " They suit you . It ' s really good to see you again , Dax . That sounds so strange . I mean , I ' m looking at a different face , hearing a different voice , but somehow it ' s still you . " " < br > " " I know . Every time I start to think of you as just Lenara , you ' ll smile or laugh and suddenly it ' s you . " " < br > " " I thought I ' d , thought I ' d gotten over you . It ' s been so long and so much has happened . And now I know I haven ' t . " " < br > " " Shh . I ' ve missed you . I ' ve missed you so much . " " < br > " " Everyone is trying to look out for us . Protect us from ourselves . But in the end , all that matters is how we feel and what we do about it . Because either way , we ' re the ones who have to live with the consequences . " " < br > " " That ' s the tricky part though , isn ' t it ? Living with the consequences . When you ' re not with me , when you ' re not around , it ' s like a part of me is missing . I want to be with you more than anything , but I don ' t think that I can do this . Dax , I am not like you . I don ' t have a little Curzon inside me telling me to be impulsive , to ignore the rules , to give up everything I ' ve worked for . " " < br > " " Can you really walk away from me , from us ? After all this time , we ' re together . Don ' t throw that away . " " < br > Appendices . Background information . Lenara Kahn was played by actress Susanna Thompson in her third of four " Star Trek " appearances . In the first draft script of " Rejoined " , Lenara ' s surname was " Yor " . The episode ' s final draft script for " Rejoined " stated the pronunciation of Lenara ' s first name as " le - NAR - ruh CON " . She was described , in the same script , as being aged approximately in her mid - thirties . This would put Kahn ' s year of birth around 2337 . Two of the costumes worn by Thompson were later sold off in the It ' s A Wrap ! sale and auction on eBay . The first was a long - sleeved dress top and corresponding bottoms , that featured a multicolored metallic brocade , purple accents around the collar and a blue chiffon drape , while the second was a full - length , long - sleeved , silver - blue dress with a textured floral pattern . Both costumes were sold for $ 228 . 50 each . The silver - blue dress was later reused and worn by actress Ramona Case in a later episode . On preparing for her role in the episode , Thompson said in a 2003 interview " " . . . the prep for it was to quickly try to understand what a Trill is and what type of backstory that they may have created that they didn ' t put down on paper for these two people . And then to work with Avery [ Brooks ] , and he was really big on backstory , and just trying to give us a history . First time working on " Star Trek " where a director wanted me to come in prior to the first day you start shooting , so to get Terry [ Farrell ] and I together . I felt very safe with him . " " Of working with Terry Farrell , she further commented " " She was great . She was just so easy and comforting , very focused with me . She had a great sense of humor and she worked really , really hard . This episode was very important to her . And I think she and Avery knew that . I ' m not so sure about her history throughout the series but I know that a lot of her heart went into this episode too . And it was nice that Avery brought us in to meet each other . And I feel like I ' m a pretty comfortable person and she certainly was , and Avery wanted us to have that contact . She was great to work with . I just loved it . " " ( , Season 4 DVD Hidden File 04 ) Terry Farrell commented , " " The great thing about ' Rejoined ' was that nobody had a problem with the fact that they were both women – the only problem was that they were married in previous lives . Making that episode was a wonderful and emotionally - charged experience and I was really pleased of the finished product . " " Reception to the kiss scene was controversial , as Ronald D . Moore recalled , " " Some of the response was pretty angry . Some felt betrayed , didn ' t want to see this in their homes . An affiliate down south cut the kiss from their broadcast . I remember thinking , it ' s been a long time since " Star Trek " was banned in the South . Maybe it ' s time that we get banned again . " " Similarly , Rene Echevarria noted , " " My mother was absolutely scandalized by the episode . Shocked and dismayed . She told me , ' I can ' t believe you did that . There should have been a parental guidance warning . ' But it ' s exactly what I wanted to happen , to sneak it right into the living room . " " ( " " , p . 279 ) The Trill taboo against re - association was something Michael Piller came up with early on in the series , later expanded by Ronald D . Moore . As Echevarria recalled , " " The existence of the taboo meant we could do a tragic love story . But it was Ron who had this inspiration to make the ex another woman . We could tell the same story and the taboo about re - association would track with our own taboo about homosexuality . We could tell the story without ever talking about the fact they were two women . ( " " , p . 279 ) The decision to make Kahn a woman went all the way up to Executive Producers Ira Steven Behr and Rick Berman , as well as the studio executives . " " They questioned us closely about our intentions and why we were doing it , and how it would work in the story , and how far we were going to go , " " recalled Ronald D . Moore . " " They saw that we were sincere , that it was a good story , that we could say something with the show , that it was what " Star Trek " stood for and that it would actually be something to be proud of . They went for it . " " ( " " , p . 280 ) Lenara ' s experiment to create an artificial wormhole was a MacGuffin , " " to get us through the tale and to explain why Lenara was coming to the station , " " Moore explained . " " It had to be a science project so that Lenara and Jadzia would need to work together . " " ( " " , pp . 280 - 281 ) In his review of " Rejoined " , " Star Trek " author Keith R . A . DeCandido thought Susanna Thompson gave a " " simply superb performance " " going on to write , " " The chemistry between " [ Jadzia and Lenara ] " is perfect , as every scene they have together just sparkles . Probably the best is their first , as they awkwardly circle each other at the reception , noticing everyone looking at them , and as soon as they start actually talking to each other , they instantly fall into a routine as if they ’ d known each other all their lives — which they haven ’ t , exactly , but the memory of such is strong in both of them . " " Apocrypha . In " The Q Continuum " novels " Q - Strike " and " Q - Space " , Kahn ' s work on artificial wormholes inspires Dr . Lem Faal , a Betazoid scientist , to find a way to breach the galactic barrier in 2374 . Lieutenant Commander Data also recalls Kahn ' s work on the artificial wormhole in the " The Dominion War " novel " Behind Enemy Lines " , also set in 2374 . In the " " short story " Trill : Unjoined " , set in 2376 , Ezri Dax tells Taulin Cyl that she does not regret what happened with Lenara . The character appears in all four issues of the " " comic miniseries and is featured on the cover of issue # 1 , " " . The seventh host to the Kahn symbiont , namely Damar Kahn , appears in a mission of the video game " Star Trek Online " , set in 2409 . This suggests Lenara died some time after " Rejoined " but prior to this year .
