Blood Oath ( episode ) Three old Klingon warriors reunite on Deep Space 9 , seeking Curzon Dax , with whom they entered into a blood oath to one day exact revenge on an enemy for killing the warriors ' firstborn sons . Finding Jadzia as worthy a warrior as they felt Curzon to be , she joins the Klingons in completing their vendetta . Summary . Teaser . In his bar , Quark complains to Odo that an elderly , drunken Klingon is monopolizing one of the holosuite s , endlessly re - fighting the Battle of Klach D ' kel Brakt , a battle the Klingons won over the Romulan s a century ago . With Odo standing by , Quark shuts off the power , and the Klingon , Kor , storms out with a bottle of Breshtanti ale in his hand . He lunges drunkenly at Quark , but Odo pacifies him by telling him a " victory celebration " is awaiting him , and leads him to a holding cell to sleep it off . Koloth , Kor ' s friend , comes to bail him out ; however , when he sees Kor is still quite drunk , he furiously tells Odo to keep him . Shrugging , Kor passes out again , while Odo rolls his eyes . Act One . In Ops , Odo brings a report to Major Kira and apologizes for being late , as it ' s been a " Klingon afternoon . " Dax overhears the name and has Kor released . She reveals to him and to Koloth that she is their old friend and comrade , " Dax " – Curzon Dax having been the last host of the symbiont now inside her . Kor is delighted that their old friend now inhabits a beautiful woman ' s body , but Koloth protests that some mistake has been made . Dax realizes that their meeting has been arranged by another old friend , Kang , who arrives and tells them that he has finally found " the Albino . " Eighty - one years ago , the three Klingons and Curzon swore a blood oath to hunt down and kill the Albino , no matter what . After Dax does some convincing to Kang that she really is Dax , Kang explains he has finally tracked him down to a hideout in the Secarus system – and , to ensure that no warning causes the Albino to flee before they can reach him , Kang killed the traders who disclosed the location to him . Act Two . Walking alone with Dax on the Promenade , Kang muses that times have changed , and nothing is quite the same as it was in the Klingon Empire , not even a blood oath . With that in mind , he tells Jadzia that she has no obligation to honor her past host ' s commitments , and formally releases her from Curzon ' s oath . While on duty in Ops , Dax asks Kira about her experiences in the Bajoran Resistance and how she felt when she killed Cardassians . Kira is very uncomfortable talking about those days , but wants to know why Dax is asking . Dax reluctantly explains ; the Albino was a heinous criminal who led pirate raids on several Klingon and Federation colonies , until a task force commanded by Kang , Kor , and Koloth destroyed his power base . Although many of his followers were captured , the Albino escaped and promised revenge on the firstborn children of Kor , Koloth , and Kang . He managed to keep his promise by infecting each of the three Klingons ' firstborn sons with a deadly genetic virus ; Curzon was godfather to Kang ' s son , who was named Dax in his honor , and swore the oath along with the other three . Kira tries her best to dissuade Dax from her mission , reminding her that it was Curzon ' s godson who died , not Jadzia ' s and that she should not be expected to pay keep her former host ' s commitments . Dax is unswayed , telling Kira she still remembers how she felt when her godson died and feels like she owes it to Curzon to fulfill the oath , even if the other Klingons don ' t expect her to . Kira finishes by answering Dax ' s original question ; " " when you take someone ' s life , you lose a part of your own as well . " " Dax talks to Kor at Quark ' s , who is as joyful as ever : " " Oh , of course you should come ! The splendor of fighting and killing , a bloodbath in the cause of vengeance ; who wouldn ' t want to come ! " " But when she asks him to speak with Koloth and Kang on her behalf , he hesitates , calling himself an old man whose influence and power are long past . Dax confronts Koloth in a holosuite while he is practicing his " bat ' leth " techniques . He believes she is too young and fragile to accompany them , so she challenges him to a duel to show him that she still retains Curzon ' s skill with the weapon . After a few rounds , Koloth concedes that her presence will do honor to their cause , but Kang remains adamant in his refusal . Act Three . Dax presses the matter : ultimately , Kang does not have the right to deny her vengeance against the Albino , who killed Dax ' s godson . Angrily , Kang agrees to allow her along , storming , " " come and be damned ! " " As Dax packs in her quarters , Commander Sisko arrives to preemptively deny her a leave of absence , telling her that he cannot condone murder in the name of vengeance , nor can he understand why Jadzia feels the need to do so to honor a commitment Curzon made . Dax tells him that Curzon is a part of her , and Curzon understood and embraced the Klingon concepts of honor and vengeance . When Dax begs him not to make her disobey a direct order , Sisko does not prevent her from leaving , but warns her that she shouldn ' t expect to just return to the station like nothing has happened . Dax responds that the consequences she faces are up to him . Act Four . Aboard Kang ' s ship , on the way to the Albino ' s hideaway , the Klingons and Jadzia discuss their strategy . Kang advocates a surprise frontal assault on the compound ' s main gate . His intelligence indicates that the Albino only has forty guards , and the shock and awe of their appearance will give them a decisive advantage . Koloth and Kor endorse the plan and march out of the room triumphantly , but Dax stays to confront Kang . Unlike them , she can see that the plan is suicide , and demands to know what Kang is really up to . In fact , she says , if she didn ' t know better , she ' d think Kang had been paid to lure them into a trap . Kang admits that when he first learned the Albino ' s location , he visited the system to see if it was true , and was contacted by the Albino . The Albino offered Kang a " glorious " battle against forty of the Albino ' s best warriors and Kang accepted , believing that if he could not kill the Albino , he could die trying . Believing that Klingons embrace death too easily , Dax urges him to consider an alternative strategy . Kang insists that the Albino ' s defenses cannot be penetrated by the four of them , and victory is impossible . But Dax has the idea of disabling the guards ' phaser s , by reconfiguring the ship ' s disruptor s to bombard the compound from orbit with tetryon particles . The resulting dampening field will disable any energy weapons inside . Although the Klingons will likewise be unable to use their hand disruptors , they will have a significant advantage over the guards in hand - to - hand combat . Kang agrees , saying , " " perhaps it is a good day to live . " " Act Five . After beaming down to Secarus IV , Dax scans the area with her tricorder and detects a gravitic mine buried inside the main entrance : the Albino obviously never intended to keep his bargain with Kang . On the other hand , the booby - trap gives them the advantage , since the Albino will be focusing his defenses on the main gate . The four of them quickly work out an alternate plan of attack : Dax will create a diversion by sabotaging the compound ' s armory , drawing a fair amount of the guards away from the main house , while the Klingons disable the power station , knocking out the Albino ' s communications and scanners . However , Kor points out that if the Albino lied to Kang about facing him down honorably , he might not be in the compound , or even on the planet . Koloth tells everyone to wait for a few minutes while he goes and asks somebody . The others wonder if he ' s gone insane , but sure enough , he comes back a few minutes later , having stealthily ambushed a " " very helpful " " guard , who has confirmed the Albino ' s presence . The four warriors prepare to split up to fulfill their roles in the attack , and Kang locks hands with his fellow Klingons : " " May Kahless guide us on this day of vengance ! " " After a moment ' s hesitation , Dax puts her hand on the others ' . When the armory explodes , the Albino realizes that his trap has been outmaneuvered . Before he can order his guards to draw back into the house , the power station is sabotaged , leaving him trapped inside his main hall with his Markalian aide and only a few guards , with no way to signal the others and no functioning phasers . The Klingons and Dax storm into the hall and fight his guards hand - to - hand . Koloth is mortally wounded when a guard stabs him in the back , while Kang fights his way up the stairs through to the Albino . The Albino manages to mortally wound Kang , but turns to find Dax ' s " bat ' leth " at his throat . She introduces herself as the former Curzon Dax , and he smirks that she doesn ' t have it in her to murder him , alluding to the traditional consuming of the enemy ' s heart once they have been slain . She hesitates , and meanwhile Kang stabs his knife into the Albino ' s back . He falls to the bottom of the stairs to his death . On the surface , he thanks Dax for the act of friendship in " letting " him have the death blow , but the knowing eyes between long friends hints at the deeper reality : that Kang has saved Jadzia from being forced to make the decision to kill the Albino . Kang utters , " " It is a good day to die , " " before dying . Dax murmurs sadly , " " It ' s never a good day to lose a friend . " " The only Klingon left standing , Kor , sings in honor of his fallen comrades , as he stands over the body of the dead Albino . Dax returns to the station and resumes her post ; however , it is clear from the looks of both Kira and Sisko that they may not be able to regard her the same way again . Memorable quotes .
