Recap: Star Trek Deep Space Nine S 05 E 15 By Infernos Light

A disturbing new alliance forces the Federation and Klingon empire to put their differences aside and stave off the new threat of a Dominion-Cardassian alliance.


  • Actor Allusion: A possible one: actor Alexander Siddig, who plays Dr. Bashir (and his changeling doppelganger), is the real-life nephew of actor Malcolm Mcdowell, who had played the villain Tolian Soren in the 1994 movie Star Trek: Generations. Here, the changeling Bashir tries to blow up a star using a Trilithium explosive, just like Soren did in the movie.
  • Apocalypse How: Attempted by the changelings on a stellar scope; Defied by Major Kira.
  • Because I'm Jonesy: When the station receives a message from the Gamma Quadrant sent by Dr. Bashir, and then the crew learns that the Bashir on their station is no longer aboard, Sisko realizes that their Bashir is almost certainly a changeling.
  • Continuity Nod: the changeling's attempt to blow up a star with a Trilithium explosive is a nod back to Star Trek: Generations.
  • Day of the Jackboot: After a year of democratic rule, Cardassia is once again ruled by the fascists.
  • Determinator: Worf absolutely refuses to give up the fight against the Jem'Hadar First, even though he can barely stand up. This earns the First's respect.
  • Enemy Mine: The Klingons and Romulans put their problems with the Federation aside to join against the Cardassian-Dominion threat.
    • Not to mention all the prisoners in the compound to escape.
  • Face Your Fears: Garak faces his severe claustrophobia to finish his work on the transmitter. Even Worf and Martok are impressed.
  • Famed In-Story: Martok promises that Worf will have a song written about his fight against the Jem'Hadar. He also offers to include Bashir, "the healer who bound the warrior's wounds so he could fight again!"
  • Godzilla Threshold: Going to warp inside a solar system is portrayed as a dangerous maneuver, but Kira points out that if they don't, there won't be a solar system left.
  • Honor Before Reason: Why Worf continues to fight a losing battle, even after his opponent and another Klingon tell him to give up.
  • Oh Crap!: The Bashir changeling has this look when his runabout gets tractor-beamed short of his target.
  • Sensor Suspense: With what looks like a fleet of Dominion ships. Turns out to be a distraction while the changelings carry out their real plan.
  • Star Killing: The Dominion tries to destroy Bajor's sun with a protomatter device.
  • Taking You with Me: The Breen prisoner and a Jem'Hadar kill each other.
  • Wham Episode: Ron Moore described this two-parter as "throwing up everything into the air, and only what they caught would stay the same. Everything else, not so much"
    • Dukat joins the Dominion, installing himself as the leader of Cardassia.
    • Gowron rejoins the Khitomer Accords, making the Federation and Klingons allies again.
    • Bashir is revealed to have been replaced with a changeling for the last half-dozen episodes.
  • The Worf Effect: Initially Subverted as Worf defeats several Jem'Hadar in a row (while suffering more and more injuries), but Double Subverted when Ikat'ika wipes the floor with him. His Determinator spirit, however, remains unbroken.
    • Worf Had the Flu: By the time Worf fights the First of the Jem'Hadar on the station, Worf has already experienced progressive injuries from his previous 7+ opponents, which Bashir can only do so much about under the circumstances.
  • Worthy Opponent: Worf kicks several different kinds of ass during his forced fights on the prison asteroid. His sheer determination earns him the respect of the Jem'Hadar in charge.
    Ikat'ika: I yield. I cannot defeat this Klingon. All I can do is kill him. And that no longer holds my interest.
  • You Have Failed Me: The Vorta Deyos has Ikat'ika killed for yielding to an opponent he was winning the fight against. He also tries to have Worf killed at the same time, but Worf gets beamed out at that moment.
