Recap: Star Trek Deep Space Nine S 04 E 20 Shattered Mirror
In a spectacular display of Genre Blindness, Sisko introduces Mirror!Jennifer to Jake. Who is promptly kidnapped so the Terran Rebels can force Sisko to assist in building their own version of the Defiant.
Aside Glance: Sisko gives a brief one to the camera when it sounds like Mirror!O'Brien is guilt-tripping him into staying and helping with the battle.
Attack Pattern Alpha: Played with. Mirror!O'Brien isn't in Starfleet, so he doesn't know the attack patterns that Sisko orders.
When Sisko orders the Defiant to attack Mirror!Worf's flagship directly, O'Brien calls it "Pattern Suicide."
