Kira and Bashir are returning from the opening of a hospital on New Bajor in the Gamma Quadrant. Just before the runabout enters the wormhole, there's a sudden problem. Kira is able to solve it, but when they arrive in the Alpha Quadrant things seems to have changed. Deep Space Nine is once again orbiting Bajor and the runabout is entered by Klingons, who excuse themselves when they see Kira. It soon becomes clear the two have arrived in alternate universe. Klingons, Cardassians and Bajorans have formed an alliance against Earth and humans are forced to do slave labor on Deep Space Nine. The station is led by intendant Kira. She tells a certain Kirk traveled from the other side earlier. While Bashir is sent away to ore processing, intendant Kira seems to really like her other self. Written by Arnoud Tiele (

Did You Know?


The Star Trek (1966) Universe revisits the Mirror Universe for the first time since Star Trek: Mirror, Mirror (1967). Star Trek: The Next Generation (1987) never visited that theme, although similar parallel universes were viewed in episodes such as Star Trek: The Next Generation: Yesterday's Enterprise (1990) and Star Trek: The Next Generation: Parallels (1993). The Mirror Universe would return in follow-up episodes of Star Trek: Deep Space Nine (1993), and also be featured in Star Trek: Voyager (1995) and Star Trek: Enterprise (2001). See more »

Through the looking glass
31 March 2010 | by (United Kingdom) – See all my reviews

While returning from the Gamma Quadrant the shuttle which Kira and Dr Bashir are aboard suffers from a problem with one of its engines leading to them entering the worm hole rather faster than intended. When they get through in one piece they are pleased until they see that DS9 isn't where it is supposed to be. They don't have time to wonder where it might be when a Klingon ship appears and two warriors beam aboard. These two are shocked to see Kira aboard and are very deferential. They offer to escort them back to DS9 which is near Bajor for some reason. It turns out that the accident sent them to the parallel universe first visited by Captain Kirk in the original series. Life is very different here; humans are slaves and "Intendant Kira" runs the station. Bashir is set to work in the ore refinery where he meets "Smiley" O'Brien and a slave driving Odo. The doctor and Major Kira must find a way to get back home, it is difficult for them to tell who they can trust as the counterparts of their friends are very different.

This was a fun episode that gave us a chance to see how the actions of Kirk a century ago lead to the enslavement of humanity and the rise of an alliance of the Klingons and Cardassians. Nana Visitor did a good job as the two very different versions of Kira however I think Avery Brooks is much better as the serious Commander Sisko than here where he seemed rather hammy laughing like a pantomime pirate. As this was in the mirror universe characters who would normally be safe from death can be killed... although I won't say which ones to avoid spoiling it.
