Hippocratic Oath ( episode ) Bashir tries to help members of a Jem ' Hadar unit free themselves of their addiction to the drug the Founders use to control them . Meanwhile , Worf tries to adjust to life aboard DS9 . Summary . Teaser . Worf sits alone in Quark ' s , his eyes shifting between a PADD and a Markalian across the room . When Quark observes the poor quality of the Markalian ' s mugshot on the PADD , Worf is not amused . The Markalian is a known criminal , but Quark claims everyone is welcome at his bar . The Ferengi goes over to talk to the Markalian as Major Kira approaches and sits down with Worf . She agrees with Worf ' s observation that Quark is likely plotting something with the Markalian , yet she seems unconcerned , reassuring Worf that Odo keeps Quark in check . Worf agrees , but adds that Quark is not in prison . Meanwhile , on the runabout , O ' Brien and Doctor Bashir are discussing Keiko O ' Brien ' s return to Deep Space 9 after spending several months on Bajor . Keiko is upset that her husband set up a workshop in their bedroom while she was gone , as she thinks it is a subconscious attempt to push her out of his life ; although Miles does not think he has any motive , Bashir claims the opposite is true : Miles ' desire to be " closer " to his wife is the reason , for the bedroom reminds him of her . O ' Brien is relieved to hear this and wishes his wife was more like Bashir – though he tries to hide it . The conversation is interrupted when they detect a magneton pulse emanating from a nearby planet , likely the result of a damaged warp drive . However , a plasma field prevents the runabout ' s sensor s from scanning the planet . The field causes them to crash land in the process . The officers emerge to find themselves prisoners of the Jem ' Hadar . Act One . On the planet , Bashir and O ' Brien are interrogated . The Jem ' Hadar can easily read their rank and specialty from their uniforms . Interestingly , they place value on engineering targets rather than science and medical , revealing a bit about their tactics . One of the Jem ' Hadar wants to kill Bashir and use O ' Brien for intelligence , but the lead Jem ' Hadar disagrees and brings them to their complex . Meanwhile , Worf discusses with Captain Sisko and Odo the Markalian aboard the station and how he is likely plotting an illegal activity . Odo doesn ' t appreciate Worf attempting to interfere with his duties and assures Captain Sisko that he ' s already conducting an investigation . Sisko allows Odo to proceed and , while understanding Worf ' s position and appreciating his vigilance , reminds the Klingon that he is no longer a security officer but is in charge of coordinating all Starfleet activity in the sector . Worf promises not to let the incident interfere with his duties . On the planet , Bashir and O ' Brien are in a holding force field , while discussing the fact that the Jem ' Hadar look rather " jumpy " . Before their conversation can go further , the lead soldier , Goran ' Agar , comes and takes Bashir to an isolated section of their complex . Act Two . Bashir is told that he is now working for the Jem ' Hadar . Bashir refuses , but is then told of a story that he can ' t believe . The lead Jem ' Hadar has freed himself of his need for ketracel - white . He believes that some aspect of the planet has freed him from his addiction , and wants Bashir to find a way for all Jem ' Hadar to live without the need for ketracel - white . Bashir is still a little hesitant to help the Jem ' Hadar , so he is led to an area where there are several soldiers obviously in withdrawal stages . A slight touch to any one of them results in excruciating pain . Upon seeing this , Bashir is once again asked if he will help . He says yes , but only with Chief O ' Brien ' s assistance . The soldiers then receive the white necessary to relieve their symptoms . Worf continues to observe the Markalian , becoming convinced that he is planning an illicit deal with Quark . He confronts Odo , questioning his ability to do his job , but Odo dismisses him . Worf later acts on his own initiative to arrest the Markalian during an exchange with Quark , only to discover that the " deal " was actually a sting operation masterminded by Odo to infiltrate the smuggling operation . Odo had posed as a bag of payment , and had intended to gather information once he was on board the Markalian ' s ship , but is content to merely arrest him and confiscate the goods from Quark . O ' Brien and Bashir go to work after a couple days . Bashir has run tests , but , in the meantime , O ' Brien has been working on a makeshift weapon to subdue the guard . Quietly , he explains that they will get the guard ' s gun and run to the runabout . Then , Goran ' Agar and a few others arrive to check on the progress . His second , Arak ' Taral , picks up the device O ' Brien was working on , O ' Brien explaining that it for scanner resolution . He inadvertently triggers the weapon . Bashir and O ' Brien are quickly subdued , but the second refuses to release his hands from O ' Brien ' s neck . Act Three . Bashir tends to the guard who was hit by the device . The guard now cannot stand , but Bashir can fix the wound with surgery . Revealing some more about their rules , the injured Jem ' Hadar expects to be killed rather than be a burden on the others . Bashir objects , but , interestingly , so does Goran ' Agar . He says that is one of the Vorta ' s rules , and they will not live by them any longer . Meanwhile , Worf covertly observes Quark waiting for the smuggler from the second floor of the bar . Quark starts inspecting the crystals and Worf then leaves to confront Odo about the situation , saying he doesn ' t appear to be addressing the situation at all . Odo brushes him off , saying he doesn ' t need him interfering in the way he conducts his duties . Doctor Bashir comes to the decision that the Jem ' Hadar deserve freedom , and feels that , once free of the drug , they may no longer be as murderous and could live peacefully . Despite his research , he was no closer to discovering why the lead Jem ' Hadar did not need ketracel - white . Inspecting Goran ' Agar , he finds his body is producing the white itself , but can ' t explain it . Bashir also mentions the Jem ' Hadar child they found and the fact that Odo helped them . Goran ' Agar reveals they almost worship the Founders , but they do not talk to them . Back in the cell with O ' Brien , Bashir relays his newfound opinion of the Jem ' Hadar , but O ' Brien is skeptical . He says they know Federation doctors are trained to feel sympathy , meaning they ' re manipulating Bashir . Bashir says they should help him , as the effort could end the Dominion . O ' Brien is shocked , saying Bashir is just guessing and that the Jem ' Hadar are simply killers , without any other purpose in life . At least , in the Dominion , they are kept in check . Bashir replies that they are still people . Finally , Bashir ends the conversation by pulling rank and ordering O ' Brien to help him . With the second watching him , O ' Brien removes something from the runabout ' s floor . In a quick move , O ' Brien creates a distraction and transports outside . With tricorder in hand , he ' s off . Act Four . Bashir and Goran ' Agar discuss the cure , but Bashir has ruled out all external factors . Goran ' Agar insists there were no anomalous factors from four years ago , so Bashir thinks it ' s simply genetic – that Goran ' Agar was never addicted to the drug in the first place . Then , his second informs them O ' Brien escaped . Goran ' Agar orders him to find him and bring him back alive , but he is now convinced Goran ' Agar is weak and believing a lie . He leaves to capture O ' Brien , and Goran ' Agar leaves to follow , but not before telling Bashir he will not be protected any longer by his men . Bashir gives his word he will not try to escape . Back on the station , Quark is finalizing the deal when Worf enters to arrest the smuggler . They ' re both surprised , but then the bag containing the latinum turns into Odo , as he was about to infiltrate the real buyer that the smuggler was really working for . Worf had been interfering in the investigation of a larger plot , and Odo keeps undercover missions to himself . Further , he doesn ' t report to Worf , and felt his presence actually helped a bit since it distracts from Odo ' s efforts . Odo confiscates the crystal and the smuggler , leaving Worf embarrassed . Meanwhile , O ' Brien uses the tricorder to confuse the search party , and rigs up a trap for one of them to get a weapon . When O ' Brien finally meets up with Bashir to bring him to the runabout , Bashir refuses to leave . Act Five . Bashir insists that he can find a cure . O ' Brien is shocked again , and waits to convince him . O ' Brien then destroys Bashir ' s equipment , and informs Bashir that charges can be filed against him when they return to DS9 . Goran ' Agar finds them , and escorts them away from the research area . As they approach the runabout , Arak ' Taral spots them , but Goran ' Agar shoots him instead . Goran ' Agar sends the officers off on the runabout , and returns to his men to ease their withdrawal from ketracel - white the only way left open to him : by killing them . When O ' Brien confirms that he has been a soldier , Goran ' Agar asks him to explain it to Bashir . Worf , meanwhile , has approached Captain Sisko in order to inform him about his part in disrupting Odo ' s investigation . Sisko is sympathetic , and reminds him that things on the station are not always as black - and - white as they might be on a starship , " and Quark is definitely a shade of grey . " He tells Worf that he will need time to adjust to the unwritten rules of the station , but is confident that Worf will eventually fit in . As they return to the station , O ' Brien apologizes and says that he took the only course of action that would save Bashir ' s life , while Bashir restates his responsibilities as a doctor and that O ' Brien condemned the men to death . They decide to cancel their weekly darts game , but agree to take it up again in a few days . Memorable quotes . " " You are a soldier ? " " " " I have been . " " " " Then you explain . " " " " I have fought against races that believe in mythical beings that guide their destinies and await them after death . They call them gods . . . The Founders are like gods to the Jem ' Hadar . But our gods never talk to us , and they don ' t wait for us after death . They only want us to fight for them . . . and to die for them . " " " " He ' s their commander . They trusted him . He can ' t leave them . " " " " Good work , Chief . Keep this up , you may make a fine officer some day . " " " " Oh , thank you Lieutenant . Coming from you , that means a lot to me . " " " " So we do not help them and that ' s the end of it ! " " " " No , that is not the end of it . I am the senior officer here and I have decided what we ' re going to do . Now , I need the bio - spectral phase discriminator from the runabout ' s sensor array . I haven ' t got the technical skills to remove it , so I ' m ordering you to do it . Now , is that clear ? " " " Yes , " sir " . " " " " Odo keeps him in check . " " " " Yes . . . but not in prison . " " " " A lovely place . Smells like a garbage dump ! " " " " I ' m sorry I couldn ' t find a nicer place to crash land . Well , should we try again ? " " " " You are what Starfleet refers to as a non - com . " " " " That ' s right . " " " " You must have a great deal of experience . " " " " I ' ve been around . " " " " That makes you a priority target . We will kill you first . " " " " Keiko only spends a few days at a time on the station . I ' m the one living in those quarters . And if I wanna set up . . . a little workshop in the bedroom . . . " " " " You set up a workshop in the bedroom ? " " " " Yeah . I don ' t use it when she ' s visiting . " " " " No , of course not . " " " " She says that I ' m trying to live like a bachelor again . That I ' m expressing a subconscious desire to push her out of our quarters . " " " " Now , that is ridiculous ! I mean , if anything , by spending your free time in the bedroom , a place you intimately associate with Keiko , you ' re actually expressing a desire to be closer to her , during her absence . It ' s quite touching , really ! " " " " Exactly ! Exactly ! See , you understand ! Now why can ' t she see that ? Why can ' t she be more like , uh . . . " " " " More like . . . ? " " " " Err , um , a man , more like a man . " " " " So . You wish Keiko was a man . " " " " I wish I was on this trip with someone else , that ' s what I wish . " " " " I knew you once . Trusted you . Obeyed you without question . But now you ' re like this Human : weak , soft , inferior . If being free of white means becoming like you , I don ' t want to be cured . " " " " I ' d hate to think what would make the Jem ' Hadar jumpy . " " " " When I served aboard the " Enterprise " , I always knew who were my allies and who were my enemies . " " " " Let ' s just say DS9 has more shades of gray . And Quark " definitely " is a shade of gray . He has his own set of rules , and he follows them diligently . Once you understand them , you understand Quark . I ' d say that ' s true of everyone here . You ' ll fit in , commander . Give it time . " " Links and references .
