Recap / Star Trek Deep Space Nine S 03 E 26 The Adversary

The newly promoted Captain Sisko and crew head for the Tzenkethi system to quell possible violence from a coup. But things take a turn for the worse when a saboteur begins to interfere. And not just any saboteur. A Changeling.

Tropes

  • The 47 Society: There are 47 people on the Defiant.
  • Bait and Switch: The first lines are Sisko says are that this is his last entry to his commander's log and how fulfilling the past three years have been, as though leading up to his leaving the station. Then the scene switches to Jake looking solemn and saying that he's been wanting to tell his dad something for a long time. Turns out it's a question of semantics—from now on, Sisko will be dictating a captain's log, and Jake is just stoked to be addressing his dad by that rank.
  • Call Back: To Bashir's engineering extension course.
  • The Captain: Sisko officially becomes this after three seasons of Commanding Coolness.
  • Captain's Log: Sisko's first entry as Captain.
  • Foreshadowing: Eddington's desire to be in the captain's chair comes up when he congratulates Sisko on his promotion.
  • Gunboat Diplomacy: The idea of the mission, as far as Sisko's told—the Defiant goes on patrol to make sure that the Tzenkethi behave themselves.
  • Guns Akimbo: Sisko during a Mexican Standoff with Kira and a paranoid Bolian.
  • Kill and Replace: It's implied that Ambassador Krajensky was killed on his way to Risa and the changeling took his place.
  • Let's You and Him Fight: The Founders' plan is to make the Federation and the Tzenkethi fight each other, weakening both of them.
  • My God, What Have I Done?: Odo doesn't say it, but it's written all over his face when he kills the changeling.
  • No OSHA Compliance: While it does at least have a protective forcefield around it, the warp core of the Defiant emits enough radiation that anyone who comes into contact with the unshielded core will instantly get a lethal dose, and the engineering section will apparently become dangerously radioactive after a prolonged period without the forcefield in place. By contrast, people were able to touch the unshielded warp core of the Enterprise-D several times over on TNG with no ill-effects.
  • Non-Standard Character Design: The Bolian in this episode has a far more muscular build than the other, more portly, members of his species seen in Trekdom
  • On Three: Sisko and a Red Shirt are about to do this when the changeling attacks and takes out the Red Shirt.
  • Paranoia Fuel: A quite unsettling In-Universe example. The end of episode quote sums it up.
    Odo: You are too late. We are everywhere.
    • The Bolian is quite paranoid about whether or not Kira is the changeling.
  • Punctuated! For! Emphasis!: Odo resisting the changeling's attempt to turn him against Starfleet: "I...don't...think...so!"
  • Self-Destruct Mechanism: Sisko is willing to use it to keep the Founder-controlled Defiant from attacking the Tzenkethi. Fortunately, he aborts it just in time. Complete with a verbal version of a Two-Keyed Lock (voice authorizations from Sisko and Kira).
  • Shipper on Deck: Jadzia interrogates Sisko on whether or not he's told Kassidy about his promotion, what he counts as "dates" and where he's taking her next—she also knows more about Kassidy's cargo route than he does.
  • Shout-Out:
  • Spot the Imposter: Subverted when O'Brien is faced with two Odos, but doesn't bother trying to figure out who's who. Instead, he has his assistant hold them both at gunpoint while he keeps working.
    • But also invoked earlier when Sisko, Kira and the Bolian security officer are all pointing weapons at each other. Odo points out that Sisko can't be the changeling because he's bleeding. Any piece of a changeling that is separated reverts back to its original gelatinous form, so off to the infirmary for blood samples.
  • Tempting Fate: Odo remarks about how no changeling has ever harmed another and how he's never had to kill anyone. Guess what happens during the climax.
  • That's What I Would Do: Eddington encourages Odo to do this regarding the changeling. Unfortunately, Odo's understanding of his own people is too limited to be of much help.
  • We Are Everywhere: The Founder's last words to Odo.
  • You Have to Believe Me: Eddington trying to convince everyone else that he's not the Founder. It doesn't work—until two Bashirs show up.
