Professor Jennifer Sisko uses Jake to lure Sisko to the "mirror universe" to help the rebels build another starship Defiant.


Jennifer Sisko from the mirror universe visits Captain Sisko's quarters. Jake Sisko, although he knows Jennifer is not his mother, becomes very affectionate to her. Benjamin is then called to duty, and he is forced to leave the two alone.

When he returns, he discovers they have left the station, leaving behind a multidimensional transporter device. Sisko tries to follow this trail, accompanied by Major Kira and Chief O'Brien, only to discover the device was programmed to transport him to the mirror universe alone.

Assembling the ISS Defiant

On Terok Nor (which the Terran Rebellion had captured from the Klingon-Cardassian Alliance), Smiley explains they have built a copy of the USS Defiant based on the data and schematics that Smiley downloaded from Deep Space 9's computers. Like the original, this copy has structural problems, and the rebels need Sisko's help to prepare it for an upcoming battle with the Alliance. Smiley is willing to transport the Siskos back to their universe before the battle begins, but only after the modifications are complete. Benjamin agrees to help them and starts working hard. Meanwhile, Jake spends most of his time with the counterpart of his mother.

The Alliance attack, commanded by Regent Worf, is expected in four days – likely not enough time to finish the modifications to the Defiant. To stall for time for the much needed repairs, Bashir and Jadzia Dax pilot a smaller ship to intercept the Klingon ships. Jennifer approaches Sisko and offers to send Jake back home immediately, even though Sisko has not yet finished the repairs he promised. Sisko agrees that Jake should get home to his universe as quickly as possible. As Jennifer and Jake make their way through the airlock, they are trapped by Intendant Kira. Kira had been captured by the rebels when they took control of the station but was freed by Nog as a thank you for Kira earlier killing Quark and Rom, allowing Nog to inherit the bar. Kira shot Nog to ensure he wouldn't tell anyone that she was heading for Bajor; taking advantage of the rebels' being distracted by the battle against the Alliance, Kira was heading to her ship when she captured Jake and Jennifer. Jennifer agrees to go with Kira to Bajor as long as Jake isn't forced to go; planning to eliminate Jake as she did with Nog, Kira shoots at him, only for Jennifer to jump in front of the blast. Kira spares Jake's life once she realizes that he is Sisko's son. She tells Jake to give his father a message – that Sisko is now in her debt for sparing his son's life, and it is a debt on which she intends to collect.

At the suggestion of Garak (who fled Terok Nor and is now kept in chains by the Regent), Worf opts for a faster transfer and arrives on the second day of repairs, while the Defiant's modifications are barely installed. Sisko then resolves to command the Defiant himself, which Smiley gladly accepts. In battle, the Defiant makes quick work of the smaller Klingon Birds-of-Prey and inflicts heavy damage on the larger Galor-class cruisers. Although the small Defiant is heavily outgunned by the Regent's flagship, under the piloting of Captain Sisko the Rebel ship inflicts major damage on the massive warship while avoiding most return fire. The small ship commanded by Bashir and Dax arrives just in time to assist the Defiant in the skirmish, and together the two ships force the Regent's fleet to abandon his goal of taking Terok Nor and retreat from the battlefield.

Sisko returns from the battle to find Jake in the infirmary with Jennifer, who is clinging to life. With her last words, Jennifer tells Sisko that she knew they were still connected, to which he responds, "always." Sisko and Jake share an emotional hug, and Sisko suggests that they return home to Deep Space 9.

Memorable quotesEdit

"You remember Captain Bashir."
"Captain Bashir, Captain O'Brien, Captain Sisko. We may not have enough weapons or troops or ships but we have plenty of captains."

- Mirror O'Brien and Sisko

"This time, I will deal with the rebels myself."

- Mirror Worf, referencing Darth Vader's line from Star Wars Episode IV: A New Hope (citation needededit)

"When we first met, there was a... a connection between us. Now because of what I've done it's gone, isn't it?"
"I'm not sure it was real to begin with."

- Mirror Jennifer and Sisko

"That Cruiser has us in weapons range. Do we make a run for it?"
"We run alright, right at it!"
"Ahh! Pattern suicide."

- Mirror O'Brien and Captain Sisko

"The Intendant was bad enough! She was irrational, accusatory, unappreciative but at least..."
"At least what?"
"At least I was able to please her now and then."
"You are not my type."
"I never said I was."

- Mirror Garak while being chained up near Mirror Worf

"Terok Nor will soon be ours again! Then you can spend the rest of your life contemplating your failure as you labor alongside the other slaves in the ore processing center!"
"It's nice to have something to look forward to."

- Mirror Worf and Mirror Garak

"You know, I bet if we put our... heads together, we could create a little excitement for ourselves."
"You sentenced my wife to death."
"Isn't that a coincidence? I was hoping you weren't married."

- Intendant Kira and guard

"Make it so!"

- Mirror Worf, using one of Jean-Luc Picard's famous lines

"Forgive me my Regent, but perhaps the moment has arrived to remove your august presence from the battlefield!"

- Garak (mirror)

Background informationEdit


  • Nana Visitor says of The Intendant, "she and Kira are exactly the same person. But the Intendant's ego has been warped, so that everything that Kira would do for her people, The Intendant does for herself. She's self-serving with a capital S!"
  • Alexander Siddig says of his mirror universe counterpart, "I want him to be the inverse of Dr. Bashir, like a doppelgänger, the animus to his anima. Bashir wouldn't hurt a fly, but this guy is unstable, difficult, and stupid."
  • Colm Meaney says of Smiley, "I picture him as being a bit dirty and scuzzier than the regular O'Brien, just because of what he's had to go through. He's a trickster, and there's something sort of seedy about him. Miles, on the other hand, is straight as an arrow."
  • Aron Eisenberg says of Nog, "He was obnoxious and rude, so I played him like an edgy Quark."
  • Aron Eisenberg, a trained martial artist, did all of his own stunts for this episode.



  • The mirror universe version of Worf makes his first appearance in this episode. Michael Dorn was originally to appear as Worf in "Crossover", but he was unable to do so because he was shooting the the final season of Star Trek: The Next Generation at the time. All of his dialogue was given to Garak, and the dialogue that had been intended for Garak was used to create the character of Telok.
  • Nog is the third Ferengi to die in the mirror universe. Quark was killed by Garak in "Crossover" and Rom was killed by The Intendant in "Through the Looking Glass".
  • This is the only episode in DS9's mirror universe arc where Cirroc Lofton (Jake Sisko) appears. This episode establishes that Jake was never born in the mirror universe.
  • Dennis Madalone makes his third appearance as the Terran marauder. We learn he is a widower.
  • The weapons locker from which Kira gets the phasers in the teaser is a reuse of the prop from "Hard Time" which was shot directly before this episode. You can recognize the number 47 on its label.
  • For this episode's first terrestrial release in the UK, the scene in which Garak is stabbed by Worf was slightly edited.
  • This episode marks the last on-screen appearance of any incarnation of Jennifer Sisko, and thereby actress Felecia M. Bell.
  • Prior to the establishment of the history of the televised mirror universe, a mirror version of Worf appeared in the novel Dark Mirror, depicting a mirror universe in which the Terran Empire had survived well into the 24th century with Klingons being one of their many slave races. That version of Worf was a slave aboard the ISS Enterprise (ICC-1701-D) in 2367.

Video and DVD releasesEdit

This was one of only two volumes of DS9 (the other being 4.12) to receive a 15 certificate, due to the violent scenes in this episode and the preceding one, "Hard Time".
