It's time for the annual
Mirror Universe episode! This time, Quark gets a visit from Mirror Ezri, who tells him that Grand Nagus Zek is in the alternate universe, and he has been kidnapped by the Alliance. Quark has to provide Regent Worf with a cloaking device, and in return he'll free the Nagus. However, Quark doesn't trust the Regent to keep his word, so he and Rom travel with Ezri to the Mirror Universe to make sure the Nagus gets back home.
- Casual Kink: When a black-clad Ezri puts a knife to his throat, Quark assumes she's into fantasy roleplay. Quark does not appear adverse to the idea.
- Contrived Coincidence: The most contrived of them all. Somehow, there's a flesh and blood Mirror Universe counterpart of Vic Fontaine, leaving everyone rather confused.
- Depraved Bisexual: Intendant Kira has already proven to be this in the previous Mirror Universe episodes, but here she's depraved to the point of stupidity. Mirror Ezri has feelings for Kira, and she's using that to make Ezri do what she wants, but she also makes out with Regent Worf right in front of Ezri's eyes.
- Evil Costume Switch: Mirror Ezri wears punk/goth style clothes with black leather and all. This gets subverted though, as she's revealed to be not so evil after all (though she's still much more amoral than the regular universe Ezri).
- Girl on Girl Is Hot: Zek decides the Mirror Universe isn't so bad after seeing Mirror!Leeta promising to 'debrief' Mirror!Ezri.
- It Seemed Like a Good Idea at the Time: Why Zek tried to go into business with the Mirror Universe.
- Lampshade Hanging: The absurd qualities of the Mirror Universe trope are lampshaded, as Rom gets very confused about what things are reversed in the Mirror Universe and what aren't.
- Psycho Lesbian: Subverted. Mirror Ezri is gay, and when we meet her she's also a ruthless mercenary working for the Regent, even though Trill is one of the planets conquered by the Alliance. But later on we find out she's not without a conscience after all, and by the end of the episode she ends up joining the Rebellion.
