Synopsis: Professor Jennifer Sisko uses Jake to lure Sisko to the “mirror universe” to help the rebels build another starship Defiant.

Review: While predictable that they would have Jake meet his mother’s doppelganger in the mirror universe, it was necessary and executed really well. Jennifer’s transformation from using her mirror universe’s husband’s child to lure him over to genuinely connecting with her son is a beautiful thing to watch. Lofton plays it pretty well too, and an episode that could have been saccharine is pretty powerful. My only criticism is Jennifer’s death, which would have been powerful had she just died, but because it’s a TV show we get to see her slowly die and give one final heartfelt speech before dying two seconds later. It’s a trope I hate every time. 

Synopsis: An alternate version of Vedek Bareil arrives from the “Mirror Universe” seeking refuge.

Review: While I always welcome an episode about the mirror universe, this one was definitely a let down.

Synopsis: 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.

Review: The final mirror universe episode is pretty disappointing, and not just because it focuses on a bunch of Ferengi. I just felt like they could have done something more grandiose, with some finality, rather than leaving it open-ended.
