Following the destruction of the 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.
* BrokenAesop: "Waltz" was written as an attempt at stopping the MisaimedFandom surrounding Gul Dukat, ending with Captain Sisko telling Jadzia that evened when you live in a world full of shades of grey, evil can still exist. Except that ''the whole show'' was built upon the premise that [[GreyAndGrayMorality no nation is completely good or evil]], as even the Federation's noble ideals are subject to intense {{deconstruction}}.
* 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 give in to the Cardassians.
* ExplosiveDecompression: Dukat mentions a NoodleIncident with this happening and how he didn't sleep for a week afterward.
* HamToHamCombat: Sisko vs. Dukat. Especially during the mock-trial scene. Illusions of Kira, Damar, and Weyoun join in.
* TheReasonYouSuckSpeech: Sisko spends much of the episode [[BreakTheHaughty trying to bring down Dukat's will]]. [[NiceJobBreakingItHero He ends up strengthening it instead.]]
* SanitySlippage: And just when it looked like Dukat was getting better.
* ShutUpKirk: Dukat's rebuttal to Sisko's talks.
-->'''Dukat:''' [[SarcasmMode Behold... Benjamin Sisko: supreme arbiter of right and wrong in the universe.]]
* WhatCouldHaveBeen: Dukat's final line in this episode was supposed to be him telling Sisko, "You too will learn what it's like to lose a child." The writers scrapped this, however, both to avoid locking themselves into a specific course of action and to keep Jake from spending his future episodes living under a death threat.
