Sisko is going to retrieve information about the former Commander Eddington, who defected to the Maquis, when his contact turns out to be none other than Eddington himself. Eddington sabotages the Defiant with a cascade virus and escapes. Using a compound that is harmless to humans but hazardous to Cardassians, Eddington begins to poison Cardassian colonies. The Defiant now receives support from the USS Malinche, but the Maquis attack and disable the Starfleet ship. When his ship arrives too late to stop another attack on a Cardassian planet, Sisko decides to turn the tables and contaminate a Maquis planet with a chemical that is harmful to humans but not to Cardassians. While the two sides have to switch planets, Eddington turns himself over to the Federation authorities in order to avert a further escalation.
Errors and Explanations
Internet Movie Database
- When Eddington captures Sisko, he directs Sisko to drop his phaser on the ground. There is no indication that Sisko retrieves the weapon before beaming up to the Defiant. It may have been automatically beamed up with Sisko.
- Trilithium already has a history of being used inconsistently. In TNG Starship Mine,it was a highly volatile by-product of the warp core. In Star Trek Generations, trilithium resin was an unknown explosive. In DS9 For the Uniform, trilithium resin is suddenly familiar but not an explosive any longer, but rather a bioweapon. Perhaps there are different forms of trilithium.
- Rene on Friday, January 15, 1999 - 6:19 pm: I'm sorry...but I have to agree with Sisko's actions in this episode. These people are committing terrorist actions… Omer on Friday, January 15, 1999 - 9:12 pm: No the civil population were not commiting anything. Sisko just attacked them cause he rightfully suspected that Eddington was a more moralistic person then he was.
- Murray Leeder on Friday, January 15, 1999 - 9:20 pm: What's the difference from what Sisko did in this episode and, say, destroying a Vietcong controlled village in a napalm bang? Better yet, Sisko didn't kill *anyone*! Adam Howarter on Friday, January 15, 1999 - 10:15 pm: Well one big difference is Sisko wasn't attacking the enemy. He was attacking *his* *own* *people*!! The people he is suppose to be defending. Morality problems aside, I'm talking about the LEGAL problems. Again does anyone think that if a navy captain threatened to blow up Montana unless Eric Rudolph turned himself in he would not be relieved of his command right away and tossed in a military prison for the rest of his life? Anyone? Omer on Saturday, January 16, 1999 - 7:57 am: I'm with Adam. Andanyway, attacking civilians is wrong, unless there are VERY unique circumstances.
- Mike Ram on Sunday, November 11, 2001 - 6:42 pm: Eddington attacks the Defiant around its bridge area after initiating the virus, yet later there seems to be little damage. In "Apocalypse Rising," Dukat destroyed a Klingon Bird-Of-Prey with 2 shots, and in ST3, Kruge destroyed the Grissom with one torpedo (yes, I know in both cases the shots were at near the targets' engines). Shouldn't the Defiant at least have some scarring? Not if it’s as tough as people keep saying it is!
- John A. Lang on Thursday, December 04, 2003 - 12:16 pm: Why do they have Nog using that microphone-thingy to issue commands to the Engine Room when Sisko can use the microphone-thingy himself to issue commands? John-Boy on Wednesday, August 11, 2004 - 1:03 pm: O'Brian says that he thought it would be best to have one voice relaying orders when the bridge is exploding around the captain, to avoid confusion. And with Nog's big ears, he was the best choice.
- David (Guardian) on Thursday, June 21, 2007 - 12:08 am: If this holocommunicator was such a new device, where did Eddington get one? dotter31 on Thursday, June 21, 2007 - 5:06 pm: Eddington did say the Maquis 'appropriated' a holocommunicator.
- Eddington pulled a Seska! (i.e. leaving a deadly/destructive/counterproductive/not nice virus on the ship before defecting) So, are we supposed to conclude that Starfleet officers don't check their ships thoroughly for booby traps after incidents like this? It may have been disguised to prevent it being detected/deleted by the computer system.
- Funny. I never thought you could attach a cargo canister to a torpedo and still fit it in the launcher. David (Guardian) on Thursday, June 21, 2007 - 12:08 am: I think we can assume that there is spare room in the average torpedo casing to allow unusual components or warheads to be installed by the crew.
- Where on the "tough little ship do they keep enough poison gas to take out multiple planets? inblackestnight on Thursday, June 21, 2007 - 7:24 pm: It wasn't poison gas. It was a substance that, once detonated in the atmosphere, became poisonous and spread globally, too fast for my taste. dotter31 on Thursday, June 21, 2007 - 8:01 pm: I agree that the substance spread too fast. That seems to be a common problem on Star Trek. The TNG ep A Matter of Time has this problem as well.
- John A. Lang (Johnalang) on Saturday, January 19, 2008 - 1:51 pm: Eddington left DS9 in For the Cause, how come it took so long for his "virus" to effect the Defiant? David (Guardian) on Saturday, January 19, 2008 - 8:39 pm: Eddington activated the virus remotely when the Defiant was chasing him in this episode. Guess he was saving it for a rainy day.
