Chief O'Brien, in common clothes, suddenly pokes a phaser in Sisko's back and disappears with the captain through the transporter. It soon becomes clear he has been taken to the mirror universe, where Kira and Bashir got stuck earlier. O'Brien tells the Terrans started a rebellion against the Klingon-Cardassian-Bajoran alliance. The mirror Sisko was their leader, but he recently died. Sisko tells O'Brien he is not interested in replacing him, but his interest is piqued when O'Brien mentions the words Jennifer Sisko. In the mirror universe Sisko's wife is still alive and working for the alliance. She's constructing a sensor array that will allow them to locate the rebels in the Badlands. Sisko agrees to complete mirror Sisko's last mission: convince Jennifer to switch sides. Written by Arnoud Tiele (

[first lines]
Odo: [to Sisko] I found 27 voles in his storeroom.
Quark: Vole infestations are not uncommon on this station. If you don't believe me, ask Chief O'Brien.
Odo: When I came in, he and Morn were painting numbers on the voles' backs.
Quark: We were just... counting them, to see how many we'd caught.
Commander Sisko: You were getting ready to stage a vole fight.
Quark: A vole fight? I'm appalled. Do you really think that was what Morn was up to?
Commander Sisko: Constable, I want the voles confiscated and removed from the station.
Quark: You can't confiscate...

Commander Sisko visits the mirror universe.
3 May 2010 | by (United Kingdom) – See all my reviews

So far I've enjoyed all of the mirror universe episodes of Deep Space Nine and this one is no exception; they tend to be slightly tongue in cheek, usually restrained female characters become sexually provocative and because it is the mirror universe their counterparts of the regular characters can get killed. This story sees "Smiley" O'Brien come to Deep Space Nine and kidnap Commander Sisko so that he can take the place of Captain Sisko, who was killed, on a mission to extract a human scientist who is working for Intendant Kira. The complication is that the scientist is his wife who doesn't like him in this universe.

This episode was a lot of fun, the cast were obviously having fun playing their less restrained mirror-selves. The mission was exciting and had a nice conclusion which left the key mirror characters alive so we can look forward to seeing them again. The only thing I was left wondering at the end of the episode was did Commander Sisko tell Lt. Dax and Major Kira just how much he enjoyed the company of their mirror counterparts when he got home? Somehow I doubt it.
