He had a nightmare about running around the corridors of the station , unable to find his father . Once he feels better , he returns to sleep , adding as a footnote he misses his mother . Commander Sisko , however , still can ' t sleep . He wanders around the empty Promenade , looking out the window , and counting the star s . A mysterious woman comes up behind him , and talks to him about the stars for a while . She introduces herself as Fenna , and seems to take an interest in him . They talk for a while , about the station . She doesn ' t say much about herself , but that she can ' t stay here long . As he is offering to show her around the station , she disappears . Act One . The next morning , Commander Sisko seems to feel more alive than he did last night , even ordering a different drink , chiraltan tea ( with a double twist of lemon ) , instead of the raktajino he usually takes to start every day for the last year . Major Kira Nerys notices this , and is surprised . Lieutenant Jadzia Dax calls on the com , and asks him to meet Professor Gideon Seyetik , a terraformer and an extreme egomaniac , but charming . He arrived to the station in the , for an experimental attempt in reigniting a dead sun , Epsilon 119 . He ' s more than excited and optimistic about his experiment . Dax reminds him it is just a theory , but he brushes it off . Soon , while Commander Sisko is gazing out of the window again , Fenna reappears , and asks if his invitation to tour the station is still open . He says it is , and shows her around . In one of the upper pylons , looking at the view of the station , she always seems to say exactly the right thing . When he asks about her , she can ' t say much , and she runs off right away . Once she gets to the turbolift , she ' s gone . Act Two . At dinner , when Sisko is unable to concentrate on Jake ' s anecdote , he concludes his father is in love . As he points out , he ' s showing all three of the signs according to Nog : loss of appetite , daydreaming , smiling all the time . When Jake asks about her , Sisko is at a loss of words to describe her . Sisko next goes to see Odo to have her try to find Fenna . He ' s also unable to describe her to him ; the description is vague at best , but Odo will do what he can . Later , Dax takes him aside , wanting to know what ' s going on , as she saw the two of them on the Promenade . She reminds him that , even if she ' s a female now , Sisko used to tell Curzon about his love interests . Sisko assures her it ' s too early to talk about it . Before the dinner , the professor is charming as always , even if a bit self - congratulatory , and dominates the conversation . He explains the process of how the star will be reignited in addition to his projects , his works of art on Ligobis X , and nine - volume autobiography . Meanwhile , his wife , Nidell , has been preparing the meal , yet to meet the crew . After awhile , Seyetik goes to check on her , and she comes out to greet the crew . Surprisingly , she looks just like Fenna . Act Three . Toward the end of dinner , Seyetik details his stew recipe , which he perfected after years . Nidell , however , does not seem enthused about the dinner . Sisko whispers to Dax that she is pretending not to recognize him . When he asks her about talking to him , she knows nothing about what he ' s talking about . She doesn ' t know who Fenna is , either , but she is quite defensive . As Sisko and Dax return to the station , Sisko says he is convinced it ' s her . Odo , however , soon informs him that he couldn ' t find her after checking all of the logs . Sisko tells him not to bother , saying he did , aboard the " Prometheus " . Odo is perplexed ; he says that no one has left the " Prometheus " except for the professor . She also doesn ' t show up the next day . Sisko is puzzled . Quark offers to talk to him , recognizing the " " I ' ve been stood up " " look , but Sisko declines . When he enters his quarters , she suddenly appears , and embraces him . He asks her about Nidell , but she has never heard of her either . She doesn ' t have a twin sister , and she is still hesitant to say where she came from or who she really is . Her only reply is that she thought she was looking for a place , but she was really looking for him . After he kiss es her , she suddenly fades out of existence , as if she were non - corporeal . Act Four . After Chief Miles O ' Brien and Dax reconfigure the " Prometheus " warp drive , Sisko comes to travel along with Seyetik ' s team – and his wife . Dax doesn ' t think it ' s a good idea , but Sisko says he needs answers . En route on the bridge , Dax works with the commanding officer , Piersall , and Sisko talks with Professor Seyetik . He talks about himself on the way there . He has an expectation to keep outdoing himself , quoting a Klingon poet , G ' Trok , who wrote about a warrior having slain all his enemies . The talk turns to how he met Nidell . She was the daughter of a dignitary , and she was infatuated with him from the moment she met him . He was the first one to take her off - world , and he would give up the entire universe for her . When the " Prometheus " arrives at the dead star , Sisko suddenly sees Fenna in his quarters . He immediately calls for Dax . When Dax scans , there is no matter there , just energy . Fenna is frightened , but Sisko takes her hands and wants to help find out what ' s going on . The three go to Nidell ' s quarters , where they find Seyetik frantic over her condition . She won ' t wake up . Dax finds she is in shock . When Seyetik sees Fenna , he recognizes her and knows exactly what happened . Fenna is surprised . Act Five . Fenna doesn ' t understand , but Seyetik is outraged , as he was under the impression Fenna would never return to them . The professor explains Fenna is an illusion created by Nidell ' s unconscious mind . She is a psychoprojective telepath , and has obviously produced Fenna before . According to Dax ' s scans , there is a lot of energy coming from Nidell ' s occipital lobe . Dax doesn ' t believe she can survive more than an hour or two . She also doesn ' t believe she can do anything about it , despite Seyetik ' s insistence . Sisko has Dax take Fenna outside , and Sisko talks to Seyetik . All of the charm fades from him as he explains what ' s going on . Nidell doesn ' t know what ' s happening ; she is unconscious , and this happens when her species have strong emotions . All of his wives , he says , have trouble with him after a while ; they hate him in the end as much as they love him in the beginning . Nidell can never leave him , because her species , the Halanan s , mate for life . Sisko then goes to talk to Fenna , and explains this to her . She can ' t believe it , and doesn ' t want to die . Sisko promises to remember her , and that it ' s a dream . Dax then calls from the bridge , and says that Seyetik has launched the shuttlepod – with himself on it . Piersall has opened communications with Seyetik , and Sisko tries to convince him to turn around . However , Seyetik says he is freeing Nidell forever , and not just from her current predicament , but from her mating obligation . He cheerfully says he has even written his own obituary , which he would like Sisko to take to the Daystrom Institute . He promises to send it off . Exclaiming " " let there be light ! " " , Seyetik ' s shuttle impacts the star and it is reignited . Then , Fenna disappears from the bridge . Nidell says goodbye , and thanks Sisko . She says she will probably stay on her homeworld the rest of her life , and wishes she could remember Fenna , but she can ' t . Before she leaves , she asks Sisko what Fenna was like , and is told , " " She was just like you " . " Memorable quotes . " " Admit it , Chief , if you were on a station where everything worked , you ' d be miserable . " " " " You may be right , sir . " [ sparks fly from the panel he ' s working on ] " But I ' d be willing to give it a try ! " " " " Something wrong ? " " " " No , nothing . " " " " If something ' s bothering you , Major , I want to hear it . " " " " It ' s just that . . . every morning for the last year , I ' ve seen you walk in here and start your day with a raktajino . " " " " I " love " raktajino . " " " " I know , you never even " talk " to anyone until you ' ve had your first cup . " " " " Because I ' m not " awake " until I ' ve had my first cup . " " " " So . . . how come you ' re drinking Chiraltan tea ? " " " [ pause ] " I , uh . . . I just felt like having something different . That is " all right " with you , isn ' t it , Major ? " " " " Of course , you can drink whatever you like . " " " " Why thank you Major , I appreciate your support . " [ drinks ] " " " Do you always do that ? " " " " Do what ? " " " " Say exactly the right thing . " " " " Of course it ' ll work : I never fail ! Well , I did once , but I found it didn ' t agree with me , so I swore never to do it again , and I never break my word . " " " " The last time I saw her , she was wearing a . . . she was wearing " red . " " " It ' s hard to talk man - to - man with a woman . " " " " Commander , do you think he ' d notice if we weren ' t here when he got back ? " " " " Don ' t even think about it , major . I ' ve had dinner with about two dozen Bajoran ministers , I think you owe me this one . Besides , Seyetik is one of the Federation ' s greatest minds . " " " " I know , he told me . " " " " Commander , obviously you have mistaken me for someone else . " " " " Seems that way . . . doesn ' t it ? " " " " So honor the valiant who died ' neath your sword " " , " " But pity the warrior who slays all his foes . " " " " Keep your eye on the viewscreen , commander , you ' ll never see anything like this again . " Let there be light ! " " " I wish that I could remember Fenna . What she did , how she felt . But I can ' t , I ' m sorry . " " " " It ' s all right . I can remember for both of us . " " " " Tell me one thing . " " " " If I can . " " " " What was she like ? " " " " Fenna ? She was just . . . like you . " " Links and references .
