The Federation Alliance goes on its first major offensive against the Dominion since the retaking of DS9: the taking of the Dominion shipyards in the Chin'toka system. Meanwhile, Dukat returns to Cardassia Prime with a plan of his own - one that he believes will not only allow the Dominion to again use the wormhole, but will strike a blow against the Emissary as well.
This episode contains examples of:
- Apologetic Attacker: Dukat to Jadzia.
- Call Back: Sisko's baseball once again serves the Rule of Symbolism. At the end of the previous season, he left it on his desk, as a message to the Dominion that he would be back. Here, he takes it with him, not sure if he is coming back.
- Cannot Keep a Secret: Jadzia, when Bashir and Quark wonder what she and Worf were talking about in the holosuite:Worf: It is a private matter.
Jadzia: We're thinking about having a baby!
Worf: It was a private matter.
- Death Wail: The return of the Klingon Death Roar, under particularly horrible circumstances.
- Downer Ending: Oh boy...
- Dropped a Bridge on Her: Jadzia dies rather casually and arbitrarily. This becomes a plot point in the next two episodes, as Worf grouses about Jadzia not getting an honorable death and tries to ensure a great victory is accomplished in her name.
- Easily Forgiven: Dukat bears Damar no ill will for what happened to Ziyal, insisting that it was instead Sisko's fault.
- Famous Last Words: "Our baby would have been so beautiful." - Jadzia
- Genre Savvy: Weyoun is pissed when he learns the wormhole has been closed, but Dukat insists that cutting Sisko off from the Prophets is a great victory. The next episode shows he was right, as the course of the war changes.
- Heroic B.S.O.D.: Sisko goes into one after Jadzia dies and the Prophets disappear.
- Hypocritical Humor:Weyoun: Pah-Wraiths and Prophets...all this talk of gods strikes me as nothing more than superstitious nonsense.
Damar: You believe that the Founders are gods.
Weyoun: That's different.
Damar: In what way?
Weyoun: The Founders are gods.
- Keystone Army: Taking out the defense grid's power generator shuts down all the weapons platforms at once.
- Kill Sat: The Dominion's orbital weapon platforms.
- Killed Off for Real: Fan favorite Jadzia Dax, murdered in cold blood by a Pah-Wraith-infested Dukat.
- My Significance Sense Is Tingling: Sisko when the Pah-Wraith invades the wormhole.
- Nothing Personal: How Dukat views killing Jadzia. He was only targeting the orb, and she was in the wrong place at the wrong time.
- Pyrrhic Victory: Cardassia has been breached by the joint Federation-Romulan-Klingon forces. But Jadzia is dead, the wormhole is gone and Sisko leaves the station.
- Ramming Always Works: The Jem'Hadar fighters ram Martok's ships to buy time for the defense grid to activate.
- Red Eyes, Take Warning: When Dukat is possessed by the Pah Wraith, his eyes turn red.
- Talking to the Dead: Sisko speaks to Jadzia's coffin near the end of the episode.
- Unfriendly Fire: O'Brien tricks the weapon platforms into firing on their own power generator.
