The Emperor ' s New Cloak ( episode ) When Grand Nagus Zek is kidnapped by the Klingon - Cardassian Alliance while on a business trip into the " mirror universe " , Quark and Rom follow him there . Summary . Teaser . Odo and Quark are conversing in Quark ' s Bar as they observe Dr . Bashir and Ezri . It seems Quark is convinced that Ezri is in love with him , although Bashir – and Ezri as well , according to Odo – is not aware of it . Quark ' s obsession is interrupted when Rom runs in and anxiously informs him that Grand Nagus Zek has gone missing while on a business trip . However , Quark is not worried , assuring Rom the Nagus probably stopped on Risa . By the time he gets rid of Rom , Bashir , and Dax have left together holding hands , much to Odo ' s delight . Quark goes to his quarters to pray ( and pay ) to the Blessed Exchequer for Bashir to be sent off Deep Space 9 for a few months . He slips the latinum slips into the shrine ' s lobe in the hope that Ezri will fall for him . Shortly thereafter , the door chime rings ; it is , dressed in black and not acting at all like Dax . She assertively forces her way into the room , but as Quark learns in a recorded message from Zek , this is not a " Vulcan Love Slave " role - play but the mirror universe Ezri . In the message , Zek reveals that he is in the hands of the Klingon - Cardassian Alliance in the alternate universe , not Risa as Quark originally presumed . Apparently the Nagus is being held ransom , and Quark has three days to secure a cloaking device for the Alliance or Zek will die . Act One . Quark and Rom exit the airlock carrying the extremely heavy cloaked cloaking device they have stolen off of the , which occasionally gives off faint glimmers of light . They slowly approach the habitat ring when they hear someone coming and put the cloaking device down . Captain Sisko and General Martok walk by talking about expanding their lines from the Kalandra system , but they do a double - take as they realize Quark and Rom are idly staring at a bulkhead . Although the Ferengi give no particular reason and Sisko is confused as to what they are doing , Martok grows impatient as they do not have time for such things . Once the soldiers are gone , Quark manages to find the invisible device but burns his finger on an induction coil . They bring the cloaking device to Ezri in cargo bay 14 , where she has apparently set up the interdimensional transporter needed to travel to the alternate universe . As she gets it ready , Rom observes the striking resemblance to the Ezri he knows . However , before she leaves , Quark decides that he and Rom need to go with her to ensure they get Zek back . Ezri does not think doing so is a good idea , but as Martok angrily enters the cargo bay and comes after them , the mirror universe suddenly looks a lot more appealing . The three of them transport across with the cloaking device . Once in the alternate universe , Rom observes how normal the cargo bay on that side looks , while Quark reminds him that their counterparts are dead . The similarities soon end when – who is not a hologram – backs into the room , a phaser in each hand , followed closely by and a pair of s . Fontaine , who does not know what a hologram is , is a renegade of some sort , and guns blazing , he is shot dead by Bashir in front of Quark , Rom and Ezri . Act Two . With Fontaine dead , the Terrans turn their attention to the newly - arrived trio and the hostile emotions make it clear that Bashir and Ezri know one another . However , contrary to Rom ' s expectations , the Terrans hold them in no higher regard . They take the Ferengi and the Trill to the brig . Bashir and visit them in their holding cell , and are contemptuous towards Ezri for siding with the Alliance against the Terran Rebellion for money rather than loyalty . Bashir is eager to execute the Ferengi , but O ' Brien observes that Quark and Rom ' s Sisko would not want them in the mirror universe and suggests sending them back where they came from ( sans cloaking device ) . Quark is determined to get the Nagus back though , so they give him until morning to decide . Ezri suggests they take the offer and leave , but the Ferengi firmly refuse despite the hopeless odds . Aboard the Alliance ' s massive " Negh ' Var " - class flagship , gently massages Zek ' s lobes , intent on securing her freedom . Zek has promised Quark and Rom will deliver the cloaking device , and so long as the Intendant believes him , she appears dedicated to pleasing the older Ferengi . That night Quark talks about why he wants to save Zek ; not because he ' s married to their mother and is extremely rich , but because of loyalty . Just then , breaks into DS9 ' s brig to rescue Ezri . Unlike the " normal " Brunt , he is incredibly kind and compassionate . He even offers to take Quark and Rom along , offering them food and water . Act Three . During the ride in Brunt ' s shuttle to meet the Alliance ' s regent , Rom eagerly feasts on fried tube grub s , but becomes perplexed by the paradoxical logic of the mirror universe . He and Ezri head to bed , leaving Quark and Brunt alone . Brunt then confesses he hates the Alliance , but helps them because Ezri is his closest friend – although he hints that she is " very particular " about men , when Quark inquires about the nature of their relationship . Regent , meanwhile , has discovered the sinus - clearing wonder of beetle snuff and eagerly awaits the cloaking device . His pet is eager to kill Intendant Kira , but Worf remains firm in making his own decisions . When Quark , Rom , Ezri , and Brunt deliver the cloaking device , Worf is quite pleased and orders it operational within the hour . Quark expects the deal to complete with the Nagus ' return , but Worf does not . Kira then comes out to seductively greet Ezri and the Regent reneges on his deal with the Ferengi . Worf decided to release the Intendant for coming up with the idea to acquire the cloaking device , much to Garak ' s dismay . Quark and Rom are then imprisoned , but not killed . Act Four . As Zek reveals that he stole the interdimensional transporter schematics from Rom ' s PADD in the middle of night at their mother ' s and came to the mirror universe to find new business opportunities , Brunt feels guilty about what he and Ezri have done to the innocent Ferengi . He attempts to convince Ezri to ask the Intendant to get them out of prison , but Kira enters as he is speaking and notes that she does not want to waste a favor from the regent on them . She kills Brunt , claiming she felt he was going to betray her and holding Ezri close . On the bridge , an officer announces that long - range sensor s have detected the , so Regent Worf decides to test his new cloaking device . However , it is not yet operational , so he sends Ezri to fetch Rom . Quark claims they have no reason to help someone who has betrayed them , but Rom and Zek are eager to do whatever is necessary , as they believe Rom ' s help may allow them to survive . Despite her prior treachery , Ezri ' s motives appear genuine . Rom grows impatient with Garak ' s inability to serve as his assistant , growing defiant when Garak threatens him ; he knows Garak needs him more than he needs Garak . Meanwhile , Kira gets on Worf ' s good side in order to re - gain control of rather than the Alliance ships destroying it . Once Rom installs the device and the ship cloaks successfully , the satisfied regent allows Garak to " get rid of " the Ferengi as he sees fit . Ever a sadist , Garak relishes the thought , intending to test out a deadly and painful virus on them . Act Five . As usual , Quark uses his Ferengi cunning to get him out of a tight spot ; when Garak enters the brig with the virus , Quark and the others slyly try to convince him that they have valuable information he should want to know and negatively compare him to " their " Garak . The Terrans meanwhile begin to suspect something is wrong , knowing they should have caught the Ferengi ship by now . Smiley wonders if the regent has the cloaking device already , but Bashir is sure that , even if he does , it could not be functional yet . However , the regent ' s ship is right behind them , matching the clueless Humans ' warp speed in anticipation . Right when the regent ' s ship decloaks and tries to fire on the " Defiant " , its power grid shuts down , having been sabotaged by Rom . The Ferengi ( and Zek ' s silent Hupyrian servant , Maihar ' du ) jump Garak when the force field shuts down . Though he manages to overpower them and is ready to inject Quark with the virus , Ezri steps in and injects Garak instead . At the airlock , Ezri and company find Kira , and both Ezri and Kira are armed . Neither appears to trust the other , but they both lower their phasers slowly . However , Ezri decides not to go with Kira , having developed a conscience . She lets the Intendant go , as she owes her that much . Zek is shocked over the fact that they ' ve mentioned that Brunt is dead but Rom informs him , " " wrong Brunt " . " The Terrans return to Terok Nor triumphantly with the Regent in their custody and Ezri now on their side . After their recent ordeal , Quark offers to take Ezri back to our universe , but she decides to turn over a new leaf with the Terrans . Suddenly shows up , much to Rom ' s delight ; however , it is the " mirror " Leeta , who has never seen him in her life and has been sent to " debrief " Ezri , as the two look seductively at one another . Rom suddenly wants to go home after seeing this , to which Quark and Zek agree wholeheartedly . Memorable quotes . " " It looks like Deep Space 9 to me .
