According to Memory Alpha's In Universe Timeline, the story sequence is:
Time's Arrow : Past Prologue : The Passenger.


The Bajoran Tahna Los is beamed into DS9 after narrowly evading a pursuing Cardassian warship. Tahna belongs to the Khon-ma, a particularly ruthless terrorist group, and now seeks political asylum. Major Kira, who knows Tahna from her time in the resistance, supports the request in any way possible, acting against Commander Sisko. In the interim the two renegade Klingon sisters from the House of Duras, Lursa and B'Etor, have arrived on the station and meet with Tahna. He tries to enlist Kira's assistance to obtain a runabout but does not reveal his motive. His yet unknown goal is to detonate a bilitrium explosive, which he plans to purchase from the Duras sisters, to seal the entrance to the wormhole, and therefore eliminate the need for a Federation presence on Bajor. But the Duras sisters plan to double-cross Tahna and to deliver him to the Cardassians for a price. Sisko reluctantly allows Kira to accompany Tahna to the rendezvous with the Klingon sisters in the hope of revealing his intended target. Although Tahna manages to briefly elude Sisko and O'Brien, his plan is thwarted when Kira seizes control of the runabout, enters the wormhole, and detonates the device in the Gamma Quadrant. However, Tahna has regained control of his weapon and orders Kira to return to the Alpha Quadrant. There, Sisko gives Tahna an ultimatum, either to give himself over to the station's authorities, or to wait to be destroyed by the Cardassians. Tahna hands over his weapon to Kira, and turns himself in; Kira explains that he may come to understand why this was the right thing to do someday.

Errors and Explanations

The Nitpickers Guide for Deep Space Nine Trekkers

Plot Oversights

  1. Odo managing to compact his mass into a small rodent without becoming hot and heavy. This could be a natural ability of Odo's species.
  2. Odo being better at making a rodent nose than a human one. A human nose may be too complex.

Internet Movie Database

Plot holes

  1. Commander Sisko refers to the Cardassian ship's commander as Gul Danar. However, the Gul never introduces himself by name any time during the episode. Danar's name could be included in the ship's current ID records.

Nit Central

  1. Keith Alan Morgan (Kmorgan) on Wednesday, August 30, 2000 - 11:36 pm: In A Matter of Perspective, O'Brien had trouble beaming Riker off an exploding space station. In Emissary, O'Brien had trouble operating the Cardassian transporters on DS9. However, in this episode, O'Brien has no trouble beaming a guy off an exploding spaceship. Hmmm... Uncle Dick on Tuesday, July 31, 2001 - 2:07 am: Well, people are always being beamed off of exploding starships in Star Trek (ie Heart of Glory, Best of Both Worlds, Part II) with no problems. I assume that O'Brien read up on the tech specs of Cardassian transporters between episodes and now is able to adequately run them. Perhaps the strange beam the guy in Matter of Perspective shot at Riker interferred with transport somehow.
  2. Why would a Bajoran need to request political asylum in Bajoran space? He obviously believes Bajor has become Federation territory!
  3. If the Klingons, allies of the Federation, have declared someone to be a renegade, wouldn't the Federation have a responsibility to notify the Klingons of their whereabouts? inblackestnight on Monday, October 01, 2007 - 11:09 am: I would think so. Sisko tells Odo that "they haven't broken any laws here, you can't just throw them in jail." Well Benny, they are wanted by the Klingons, so the Constable has every right to do so. Brian FitzGerald on Monday, October 01, 2007 - 10:51 pm: Perhaps it's that they are on a Bajoran station. While the Feds probably have an extradition treaty with the Klingons the Bajorans may not. The Provisional government is still pretty new at this point.
  4. John A. Lang on Thursday, September 18, 2003 - 7:58 am: Let me get this straight, the Federation hires Kira, a reknowned terrorist from Bajor, who has no love for the Federation's presence in Bajoran territory aboard DS9....which is now Federation property & is designated to oversee the activities around the wormhole for its commercial value.(?) RIGHT! Isn't that like putting someone from Al-Quida in charge of the Department of Immigration? Josh Gould (Jgould) on Thursday, September 18, 2003 - 9:06 am: The Federation didn't hire Kira (especially cause they don't use money ;-)) - she's the Bajoran liason officer on a station which is Bajoran property, albeit under Federation administration. She was assigned by the Bajoran Militia, which, I'm guessing, is largely comprised of ex-Resistance fighters. John A. Lang on Thursday, September 18, 2003 - 10:20 am: But...wouldn't a Bajoran ambassador be more appropiate for a laison position than a terrorist? (Forgive me, I'm a little confused) Josh M on Thursday, September 18, 2003 - 1:36 pm:One, the Federation doesn't own the station. The Bajorans do and they can put whoever they want up there. To them, she's not a terrorist, she's a freedom fighter who fought off an oppressed people. The Federation may not view her as a terrorist either. The Cardassians undoubtedly do. When the U.S. became a nation, it let one of its terrorist leaders become the first president. It's not much different.

Ex Astris Scientia

  1. When one of his security officers points a phaser at Lursa and B'etor, Odo steps between them, straight into the line of fire. This way he makes it look like he disapproves of his people's use of weapons, before knowing what has happened. A good security chief would have sided with his people and let them keep control of the situation before asking any questions. Mofre likely he is taking action to prevent the situation getting out of hand.


  1. According to the episode list, the provisional stardate for this episode is 46401.
