The Defiant is thrown into the past by the Bajoran Orb of Time. But it's not just any past, it's the TOS episode "The Trouble With Tribbles", and the crew finds themselves trying to prevent an assassination attempt on James T. Kirk.This was the Deep Space Nine Milestone Celebration for the 30th anniversary of Star Trek, along with Voyager's "Flashback".
- Ascended Fanboy/The Knights Who Say "Squee!": Dax may be the most outwardly enthusiastic, but don't let that fool you. The other Starfleet officers are just as thrilled to be there and to see Kirk in action.Sisko: Excuse me, Captain. Here's tomorrow's duty roster for your approval.
Kirk: Lieutenant... uh, Lieutenant?
Sisko: Benjamin Sisko, sir. I've been on temporary assignment here. Before I leave I just want to say... it's been an honor serving with you, sir.
Kirk: All right, Lieutenant. Carry on.
Sisko: Thank you, sir.
- O'Brien stands in line, as Kirk dresses down the brawl."I lied to Captain Kirk! I wish Keiko could have been there to see it."
- O'Brien stands in line, as Kirk dresses down the brawl.
- Author Avatar: Dax's enthusiasm for the time period of the original series was a direct reflection of the writers' love for the old show.
- Bar Brawl: One of the most famous scenes in both tribble episodes. This time, O'Brien and Bashir get mixed up in it.
- Now comes with Darker and Edgier background music.
- Brick Joke: Odo buys a Tribble from Cyrano Jones, clearly not knowing anything about it. At the end of the episode, the Promenade is swarming with Tribbles. Makes his question about whether or not Sisko told Dulmer and Lucsly about the Tribbles a case of Fridge Brilliance, since it was his fault.
- We find out why Kirk was getting pelted with individual tribbles during the original episode: Dax and Sisko were tossing tribbles out of the way to scan for the one with the hidden bomb.
- Call Back: This site doesn't have the server space to list all the references to TOS in this episode.
- Two to the earlier Deep Space Nine time travel episode "Past Tense" - Sisko knows his history quite well, but Bashir doesn't.
- Cerebus Retcon: Remember the Everybody Laughs Ending of the original episode when Scotty revealed he beamed the Enterprise's tribbles to the Klingon ship? That resulted in an ecological disaster for the Klingon Empire and the Klingons hunting tribbles to extinction. Oops.
- The Charmer: Averted. At one point Kirk glances over at Dax and she smiles at him. This was all the interaction they could show given what they had to work with, and they deliberately kept it as brief as possible to explain why Kirk didn't go over to talk to her (as one would normally expect him to do with an attractive woman like her, and Dax being...well...Dax).
- Besides, Kirk was already occupied by the Tribble he'd just sat on, as well as all the other Tribbles swarming the bridge.
- Continuity Drift: Dax recognizes Bones McCoy because she had met him as Emony even before he became a doctor and also sees Spock in real for the first time. Later in the series, it's implied that Curzon was present at the Kithomer Peace Conference (though it's possible that they never actually saw each other at Khitomer).
- The Temporal Investigations agents have a brief aside about the number of Starships Enterprise, where Lucsly firmly states that there have been six. This was meant to be an reference to the newly-constructed U.S.S. Enterprise-E, which was due to make it's first appearance in Star Trek: First Contact. The eventual creation of the Enterprise NX-01 would make it rather unclear which Enterprise Lucsly had been referring to.
- Damn You, Muscle Memory: Sisko taps his Starfleet badge to contact the Defiant, before remembering that in this era they were just a logo, and he has to use a handheld communicator.
- Dangerously Short Skirt: The TOS-era miniskirts don't cover much. Not that Bashir and O'Brien complain when they see Dax...Dax: And women wore less.
- Deadpan Snarker: Odo, when questioning Worf about the Klingons' history with the tribbles, is particularly merciless with the sarcasm."Oh, another glorious chapter in Klingon history. Tell me, do they still sing songs of 'The Great Tribble Hunt?'"
- Death Glare: As they leave the station, Lucsly can be seen scowling at Dulmer for approving of Sisko meeting with Kirk.
- The Dreaded: As far as Dulmer and Lucsly are concerned, the otherwise heroic James T. Kirk is this, courtesy of his record of temporal violations.
- Establishing Character Moment: A retroactive example with Dulmer, which actually comes at the very end of the episode when he admits to Sisko that he probably would have said hello to Captain Kirk himself if he had been in his shoes. His comment, along with Lucsly's reproachful reaction, sets them up for a Red Oni, Blue Oni dynamic when they go off to star in their own novels. (Lucsly, by contrast, is every bit as stern as he appears during his introduction.)
- Fanservice with a Smile: The waitresses at the bar, in keeping with the original show.
Bashir: I think I'm going to like history.
- Dax gets into the act while showing off the 23rd century miniskirt.
- Future Imperfect: A mild, internal example, with some of the DS9 crew not knowing things about this era, such as the Starfleet division colours being different, and what Captain Kirk looks like, and even that you have to grab the hand-holds before the turbolift will respond to voice command.
- Hand Wave: Upon seeing 23rd century Klingons, the crew asks Worf about the ridges."We do not discuss it with outsiders."
- Hello, Nurse!: Dax elicits this response from Bashir and O'Brien when she reveals herself in the 23rd Century miniskirt.Sisko: In the old days, operations officers wore red, command officers wore gold...
Dax: And women wore less.
Dax enters and everyone gawks at her as she performs a Girly Skirt Twirl.
Bashir: I think I'm going to like history.
- I'm a Doctor, Not a Placeholder: Bashir is a Doctor, not an historian.
- Meet Your Early Installment Weirdness: "Those are Klingons?"
- My Own Grampa: Lampshaded when Bashir encounters an attractive woman who has the same name as his great-grandmother. He starts panicking over the possibility that he is his own great-grandfather and that he could cease to exist if he doesn't get into her pants, but O'Brien tells him he's being ridiculous.Bashir: I can't wait to get back to Deep Space Nine and see your face when you find out that I never existed!
- Mythology Gag: At the K-7 bar, O'Brien mistakes a Starfleet officer for Kirk. The actor who plays the officer was William Shatner's stunt double on TOS.
- Nerds Are Sexy: Dax finds Spock very attractive.
- Never Heard That One Before: the Temporal Investigations guys to the time related joke Dax cracks.
- No Sense of Humor: The Temporal Investigations agents have heard every single time-travel joke Eleventy Zillion times already, thank you very much. Their annoyed reactions to everyone else's repeated joking makes them Comically Serious.
- Obstructive Bureaucrats: Played with. Temporal Investigations is apparently seen by most Starfleet personnel as people who show up just to make life hell for anyone who time travels, but the two we meet are pretty reasonable guys.
- The Strange New Worlds story "Gods, Fate, and Fractals" by William Leisner runs with this, with Dulmer and Lucsly regarding themselves as the Only Sane Men in a Kirk-worshipping Starfleet that keeps casually messing with the timeline to disastrous consequence.
- Oh Crap!: Worf's reaction when he sees Odo's pet Tribble. Odo, of course, takes the opportunity to needle him about it.
- One of Us: In-Universe: Dulmer admits he'd probably do the 'one last thing' that Sisko did.
- Poetic Justice: Darvin claims that killing Kirk with a tribble-bomb is this.
- Production Foreshadowing: Dulmer says to Sisko that there have been five vessels named Enterprise, prompting Lucsly to correct him by saying "Six", referring to the Enterprise-E, which was about to debut in Star Trek: First Contact.
- Retraux: For the scenes in the past, the production crew intentionally used primitive equipment and lighting techniques to make the footage "mesh" with the original episode's.
- Red Shirt: One of the few times where a TOS Red Shirt in mortal peril survives.
- Sarcasm Mode: Bashir and O'Brien go into this when, after searching half the Enterprise for Darvin, beam over to K-7 and find Odo and Worf sitting around.Bashir: Clearly we've been going about this search business all wrong, Chief.
O'Brien: You're right. Why bother searching through twenty decks for Darvin when you can just plunk yourself down at the bar and wait for Darvin to come to you?
Odo: We have reason to believe that he'll return to this area.
O'Brien: Ahhh, yes, the raktajino.
Bashir: A vital clue that others might have missed. How fortunate that it has kept you two stuck at this bar for the past three hours having drinks while we've been crawing through conduits.
- Significant Anagram: The Temporal Investigation agents are named Dulmer and Lucsly, anagrams of Mulder and Scully.
- Stable Time Loop: Dulmer and Lucsly ask Sisko if he thought their trip to the past was one of these (even calling it by its proper name, a predestination paradox), but Sisko says no.Dulmer: Good.Lucsly: We hate those.
- Tempting Fate: Played for Laughs. The episode opens with Sisko receiving a visit from Temporal Investigations, and in the flashback, Sisko says the last thing he wants is a visit from them.
- Time Travel Tense Trouble: Odo while describing what's going on aboard Station K-7.
- Too Much Information: Sisko's reaction (as an Aside Glance) to Dax fondly remembering that McCoy "had the hands of a surgeon."
- Whole Episode Flashback: The framing story is Sisko explaining the episode's events to the Temporal Investigations agents.
