Recap / Star Trek Deep Space Nine S 05 E 05 The Assignment

Another "O'Brien must suffer" episode dealt with in a unique fashion. Keiko returns from Bajor possessed by a dangerous and malicious entity. And O'Brien is stuck fighting the clock to make sure he can get it out of his wife without killing her.


  • Adult Fear: The whole episode is this for resident Butt Monkey Miles O'Brien. Especially when Possessed!Keiko is alone with Molly.
  • A Glass in the Hand: O'Brien is compelled to act normally at a party. The stress becomes too much for him when Possessed!Keiko shows mock-affection for his daughter, and he shatters his whiskey glass.
  • Alien Lunch: Or rather, breakfast for Rom. Eager to be accepted by the engineering crews, he tries emulating them to their meal choices. First he picks Chief O'Brien but later finds out bacon disagrees with him. He later picks another crewman to copy.
  • Book Ends: The episode opens with Rom getting the breakfast of choice for the night shift crewman. And ends with him getting the breakfast of choice for the day shift crewman.
  • Brick Joke: Rom promises that if he's caught, he won't even reveal his own name (which everyone knows anyway). Later Odo grumbles that after being arresting Rom refused even to give his name.
  • Chekhov's Gun: Remember those fire caves that Jake wanted to see in Season 1? We finally learn what's in them.
  • Demonic Possession: If you consider the Wormhole Aliens spirits, anyway.
  • Foreshadowing: Jake says that he'd like to see a Pah-Wraith.
  • Hard Work Montage: When O'Brien and Rom really get down to business.
  • Hired To Hunt Himself: O'Brien is asked by Sisko if he knows of anyone who is capable of doing all these adjustments to the station.
  • I Have Your Wife: The Pah-Wraith controlling Keiko.
  • I Need to Go Iron My Dog:
    • Rather than help O'Brien tell Keiko that her plants died while she was away, Bashir claims that he has to be in the infirmary performing an operation.
      O'Brien: On who?
      Bashir: I'll find someone.
    • Followed by Molly retreating from the scene.
  • Innocuously Important Episode: The first appearance of the Pah Wraiths, who go on to be a lot more than just another Monster of the Week.
  • Ironic Birthday: Just to make things even harder on O'Brien. Not that anyone else knows that anything is wrong.
  • Out-Gambitted: The Pah-Wraith, once Rom helps O'Brien figure out what's going on.
  • Spanner in the Works: Jadzia's habit to study some spacial phenomena when she cannot sleep led her to find the entire array has been put out of place, nearly exposing the full extent of the possessed Keiko's plan.
  • The Tell: As his wife, Keiko has noticed that her husband has a small facial cue when he is about to ask a question. As the Pah-wraith possesses her has all her knowledge, it notices too.
  • Undying Loyalty: Rom to O'Brien, even when O'Brien admits he's not actually doing a top-secret project for Starfleet. O'Brien repays him for it in the end.
  • Wham Line: From Rom of all people:
    Rom: The new frequency of the deflector grid is set to turn the station into a massive chroniton array aimed directly at the wormhole. So I just wanted to know... why are we trying to kill the wormhole aliens?
  • You Have Outlived Your Usefulness: Keiko notes in the coda that she is certain the thing in her wouldn't have allowed either O'Brien live to tell what happened.
