Following the destruction of the Federation starship ''Honshu'', Sisko is severely injured and trapped alone on a deserted planet with Dukat, who becomes increasingly unstable.

!!Tropes featured:

* AbandonShip: Happens off-screen before the ''Honshu'' is destroyed.
* BadassBoast: Dukat's final lines to Sisko:
-->"I have unfinished business on Bajor! They thought I was their enemy?! They don't know what it is to be my enemy, but they will! From this day forward, Bajor is dead! All of Bajor! And this time, even their Emissary won't be able to save them!"
* CluelessAesop: "Waltz" was written as an attempt at putting a stop to the MisaimedFandom surrounding Gul Dukat, ending with Captain Sisko telling Jadzia that even when you live in a world full of shades of grey, true evil (such as Gul Dukat) can still exist. Even so, partially ''because'' of Gul Dukat's persuasive delivery of [[VillainHasAPoint considerable testimony on his own behalf]] in this episode, his fandom was not so easily dissuaded.
* CutApart: Right about the time Sisko starts transmitting a DistressCall on a Starfleet frequency, the ''Defiant'' picks up a distress call. They lock on to two life signs--and beam up two human women.
* EvilCannotComprehendGood: Dukat reveals that he couldn't understand why the Bajorans wouldn't submit to his kinder and gentler implementation of Cardassian rule.
* ExplosiveDecompression: Dukat mentions a NoodleIncident with his having to clean up the mess when this happened to another Cardassian and how he couldn't sleep for a week afterward.
* {{Foreshadowing}}: Dukat says he and Sisko won't be seeing each other for a while. They won't share a scene again until the GrandFinale.
* HamToHamCombat: Sisko vs. Dukat. Especially during the mock-trial scene. Gul Dukat's hallucinations of Kira, Damar, and Weyoun join in.
* HonorBeforeReason: Dukat alerts the ''Defiant'' to Sisko's location. He can't very well exact the ultimate revenge on him if the Captain dies on a barren planet.
** Worf believes it would be dishonorable to brazenly ignore orders in order to try to save Sisko.
* HopeSpot: The ''Defiant'' beamed aboard two people. Instead of Sisko and Dukat, it's two women from the ''Honshu''.
* PoorCommunicationKills: Kira's message that the ''Defiant'' has to depart soon is garbled by subspace interference. Bashir and O'Brien attempt to invoke this trope in order to continue searching for Sisko, but Worf and Dax shoot it down.
* TheReasonYouSuckSpeech: Sisko spends much of the episode [[BreakTheHaughty trying to undermine Dukat's resolve]]. [[NiceJobBreakingItHero He ends up strengthening it instead,]] due to Dukat's giving as good as he gets.
* SanitySlippage: Dukat undergoes a serious case of this during his isolation with Sisko, and this after he'd begun to improve in the care of the Federation's psychiatric facilities. He gets into a spirited argument with hallucinations of Kira, Damar, and Weyoun, and even tries to attack them physically a couple of times. It's during one of these attacks that Sisko realizes he's dealing with a madman, as he sees that while one of these assaults came dangerously close to hitting him, he wasn't where Dukat was ''aiming''.
* ShutUpHannibal: After Dukat's rant about how he's been way too nice to the Bajorans and he really should just have killed them all, Sisko knocks him out, retorting "[[SarcasmMode ...and]] ''[[SarcasmMode that's]]'' [[SarcasmMode why you're not an evil man!]]"
* ShutUpKirk: Dukat's rebuttal to Sisko's contentions.
-->'''Dukat:''' [[SarcasmMode Behold… Benjamin Sisko: supreme arbiter of right and wrong in the universe!]]
* ThenLetMeBeEvil: Dukat's ultimate conclusion is that he was far too lenient and forgiving toward the Bajorans who resisted his rule, and he should have just exterminated them all; so that (along with restoring that rule) is going to be his new goal from now on.
* VillainDecay: Invoked by the hallucination of Weyoun. He doubts Sisko would have any respect for Dukat if he knew about the Gul's repeated breakdowns in the hospital.
