Recap / Star Trek: The Next Generation S7E10 "Parallels"

Go To
"Captain, we're receiving 285,000 hails."

Original air date: November 29, 1993

Worf returns home from winning a Klingon bat'leth tournament and has a surprise birthday party thrown for him by Riker. As he reluctantly celebrates being "old enough," he notices several subtle changes in his own reality: The flavor of the cake changes, and Captain Picard suddenly appears at the party after sending word that wouldn't be available. As the Enterprise works on the Argus Array, a space telescope that is having problems, Worf has more dizzy spells, with more slight perception problems: officers switching positions, appearing and disappearing. More troubling, Doctor Crusher remembers him complaining about a concussion he suffered when he lost the bat'leth tournament. He returns to his room to find his champion's trophy replaced with one for ninth place.


The changes are starting to throw Worf into disarray. He claims the array was being tampered with by the Cardassians, but no one believes him. Angry, he takes himself off duty, and Troi tries to comfort him. As La Forge enters his quarters to tell him what they found with the array, he blacks out twice. The second time, he suddenly finds himself in the middle of battle with Cardassians. He struggles to shake off the effects and figure out how to operate the new controls, but not before the ship sustains heavy damage, putting La Forge in Sick Bay. Ashamed, Worf relieves himself of duty and returns to his quarters, only to discover that in this reality, Troi is his wife.

Worf has Data try to find any temporal anomalies that might explain the changes, but the now blue-eyed android can find none, so they search for commonalities in the events. Worf figures out that La Forge was present in all of them. As they head down to sickbay, the doctor (Ogawa instead of Crusher) informs them that Geordi is dead. There's nothing odd about Geordi's body, but when they check his VISOR, Worf gets dizzy again and more changes occur. Now he's First Officer of the ship under Captain William Riker, ever since Jean-Luc Picard was killed in the Borg incident (a deviation from what happens in "The Best of Both Worlds").


Data scans Worf and confirms that Worf not from this reality, where the tactical officer is Lieutenant Wesley Crusher and the conn officer is a Cardassian. A search for anomalies finds a quantum fissure in the space-time continuum that was crossed by Worf's shuttle in his own timeline. As the Enterprise scans the fissure, Worf returns to his quarters with Troi, who is still his wife. They have two children in this timeline, but Alexander doesn't exist. The scan is interrupted by a Bajoran warship (as the Bajorans turned warlike after defeating the Cardassians, who joined the Federation), and the battle disrupts the fissure; Hundreds of thousands of Enterprises appear out of nowhere. The Bajorans, suddenly not liking their odds so much, book it.

Riker sends out Worf's genetic info to the Enterprises, as it has the signature of his own reality encoded in it. They find the Enterprise that matches his information, and it sends a shuttlecraft to get him. However, before he can get to the fissure and seal it, another Enterprise starts to fire on it. This Enterprise is from a world where the Borg are everywhere, and a disheveled and panicking Captain Riker proclaims they won't go back. The "native" Enterprise tries to disable it with a photon torpedo, but it is so damaged that the shot destroys it. Worf enters the rift, fixing the anomaly.

Worf wakes up on the shuttlecraft in his own uniform, with a Bat'leth tournament champion's trophy. This time, when he returns to his room, only one person is waiting for him: Deanna Troi. Thinking about the Trois of the other universes, he decides to invite her to a romantic birthday dinner for two.


  • Ageless Birthday Episode: When asked how old he is, Worf simply says "Old enough."
  • Alternate Reality Episode: A whole bunch of them.
  • Beard of Sorrow: Captain Riker from the Borg-controlled reality has a massive unkempt beard and looks noticeably dishevelled from all the stress.
  • Bookends: Worf returning to the Enterprise after a bat'leth tournament and going to his quarters, talking with Riker along the way, suspecting a surprise birthday party waiting for him. In the beginning part of the episode, the birthday party takes place, but in the ending, it doesn't, with just Deanna Troi taking care of things until Worf returned.
  • Call-Back:
    • In one universe, Data explains that Worf's marriage to Counselor Troi was rooted in her helping him recover after his spinal cord injury in season 5's "Ethics".
    • The last universe is established as being how things would've been had they been unsuccessful in saving Picard from the Borg in "Best of Both Worlds". One of the many Enterprise copies seen at the climax is implied to be from a reality where they couldn't save Picard or stop the Borg assimilating Earth.
    • Troi alternates between much of her wardrobe throughout the series as we shift from universe to universe.
    • The Argus Array previously appeared in season 4's "The Nth Degree," and is revisited here presumably as an excuse to re-use the effects shots. While re-using effects shots like that isn't at all uncommon for Trek, it's much rarer for them to actually revisit a location, instead of just trying to pass it off as a different, but identical-looking place.
  • Captain's Log: Worf records a log entry on his way back to the Enterprise, which becomes a plot point when it changes between quantum realities.
  • Cassandra Truth: How Worf feels about nobody believing him when he points out that things aren't right. At least until Data finds the Technobabble that confirms his story.
  • Chekhov's Gun: Geordi's VISOR triggers Worf's various shifts.
  • Crapsack World: One Enterprise comes from a reality where the Borg successfully conquered the Federation in "The Best of Both Worlds". The Riker from that universe is so broken that he'd rather kill Worf than return to his universe. Of course, when the native timeline's Riker disables that Enterprise, it's already so damaged that it immediately explodes.
    Crapsack Riker: We won't go back! You don't know what it's like in our universe! The Federation's gone! The Borg is everywhere! (a console explodes in the background) We're one of the last ships left. Please, you've got to help us!
    Captain Riker: I'm sorry, there's no choice. If this works, everything will return to—
    Crapsack Riker: No! We won't go back!
  • Didn't Think This Through: When Worf asks Deanna to become Alexander's surrogate mother, legally available to care for Alexander should anything happen to Worf. Troi asks what that would make her to Worf, and he says the Klingon word for this relationship has no exact translation but the closest equivalent is that she would be his stepsister. Deanna's response? "That would make my mother your stepmother." The look on Worf's face...
    Worf: I had not considered that... (Beat) It is a risk I am willing to take.
  • Doppelgänger Gets Same Sentiment: The Primeverse Enterprise briefly receives a transmission from an alternate-universe version of Riker, now in command after Picard died during the events of "The Best of Both Worlds". He expresses his happiness to see Picard, saying that it's been a while.
  • Expendable Alternate Universe: Of the parallel timelines we get glimpses of, Riker is killed in one, Geordi gets killed in two, and Picard is long dead in one of them. On another note, this is such famous example of the trope, that J. J. Abrams used this episode to explain how the new timeline from the 2009 reboot/Kelvin Timeline works with the Prime timeline.
  • Foreshadowing: At the beginning, Riker is accompanying Worf to his quarters, and when Worf mentions it's his birthday and dreads that Riker or someone else planned a surprise party, Riker responds in disgust that he hates surprise birthday parties and would never do it to anyone else. Later when it turns out there is indeed a party Riker slaps a goofy party hat on Worf and says "I love surprise parties". In the offset it just seems like Riker was messing with him, not the result of a shifted reality.
  • Funny Background Event: When Captain Picard starts talking with Captain Riker, Commander Riker shares a surprised look with Lieutenant Worf over seeing Captain Riker and Commander Worf.
  • A Glitch in the Matrix: Worf begins to notice that small details are off from how he remembered them — the placement of decorations, the positions where people are standing, Starfleet uniforms and insignia, and even Data's eyes changing colour. As the episode progresses, the differences are magnified to the extent that Picard was killed at Wolf 359, Riker is captain of the Enterprise, and Counselor Troi is Worf's wife. Rather than being trapped in a Lotus-Eater Machine, it turns out that Worf is shifting through increasingly divergent parallel universes.
  • Guess Who I'm Marrying?: A heroic variant when Worf finds out he's married to Troi in one universe.
  • Happy Birthday to You!: The crew sings "For He's A Jolly Good Fellow" in Klingon. Worf is not amused.
    Worf: That is not a Klingon song.
    Troi: It wasn't easy to translate. There doesn't seem to be a Klingon word for "jolly".
  • The Hero's Birthday: Worf's birthday.
  • Hero of Another Story: Captain Riker and the crew of the Enterprise in the last timeline that Worf visits. Their adventures after Wolf 359 could make for an interesting series.
  • He Who Fights Monsters: In one timeline the Bajorans have turned warlike and are oppressing the Cardassians, who have joined the Federation.
  • Hilarious Outtakes: This clip of Jonathan Frakes overacting his lines at the end and running after Tracee Lee Cocco.
  • In Spite of a Nail: All the universes Worf shifts through are at least broadly similar to the "real" one, in that he and most of the same group always end up on the Enterprise. This is vaguely implied to be an actual in-universe phenomenon, as for the most part Worf's brief exposures are "nudging" him into timelines that are relatively close to his own, with only a few minor divergences in most cases.
  • It's a Long Story: Worf to Troi while confirming he's in the correct universe.
  • Killing Your Alternate Self: Captain Riker gives the order to fire on the Crapsack World Enterprise to stop them from attacking Worf. He only intended to disable them, but that Enterprise is in such bad shape that one hit destroys them.
  • Master Swordsman: In both the original and final timeline, Worf was the Klingon bat'leth tournament champion. In the 9th place timeline, an opponent cheated, and in another he had to pull out last minute due to an emergency.
  • Meaningful Background Event: The presence of a Cardassian conn officer on the bridge in one universe reveals one of the differences between that universe and the regular one a few scenes before anyone mentions it.
  • Mythology Gag: The commbadges in the last reality visited by Worf are the same as the false future seen by Riker in "Future Imperfect".
  • No OSHA Compliance: Perhaps unsurprisingly, Klingons don't seem to have safety regulations in bat'leth tournaments, leading to several competitors apparently getting "maimed."
  • Oh, Crap!: Worf practically gapes in horror when Troi tells him that their new arrangement would, in effect, make Lwaxana his mother-in-law.
  • Other Me Annoys Me: Captain Riker is very disturbed at seeing a panicked, disheveled version of himself.
  • Real Life Writes the Plot: At the time of production, the rights to the song "Happy Birthday", despite its common use, were privately held. To avoid any sort of legal issue (similar to why it took a long time before Moriarty returned to the series), the writers thought it safe to substitute "For He's a Jolly Good Fellow" instead, despite the rights owners not really seeing this as an issue.
  • Revealing Continuity Lapse: Worf notices these increasingly as the episode progresses. Each time something changes, he's in a new quantum reality.
  • Ripple Effect-Proof Memory: Worf apparently remembers everything that happened to him in the alternate quantum realities, though nobody else has any idea that anything happened until he says so.
  • Screw This, I'm Outta Here!: The Bajoran ships attacking an alternate universe Enterprise tuck their tails and run when they see thousands of Federation ships descending on them.
  • Ship Tease: The seeds for this season's Worf/Troi tease really begin here. According to Brannon Braga, the writers had actually been thinking about this angle since Season 5.
  • Spoiler Title: If you're familiar with the concept of parallel universes, the title of the episode makes it easy to figure out what's going on long before the characters do.
  • Spotting the Thread: "The cake was chocolate, but now it's yellow..."
  • Stock Footage: The only new visual effects shots for this episode are the shots of the fissure, and the shots involving thousands of Enterprise clones showing up. Probably because of the time and expense involved in creating the latter shot, every other effects shot is taken from previous episodes.
  • Surprise Party: For Worf, but only in certain of the timelines. At the end of the episode, it turns out that in the prime reality, Riker wanted to throw the surprise party, but Troi talked him out of it. So Worf and Troi share champagne instead.
  • Uneven Hybrid: Worf and Deanna's unseen children in the final alternate timeline. Their mother's half-human, half-Human Alien; their father's a full-on Rubber-Forehead Alien.
  • Wham Line: After Worf is stunned by Troi kissing him.
    Worf: I do not believe this is appropriate behavior!
    Troi: Not even for your wife?

Video Example(s):


Old Enough

In "Parallels" from "Star Trek: The Next Generation," a surprise party is held for Worf in an alternate timeline and Captain Picard has a question for him: "So, how old are you, Mister Worf?" Worf hesitates, then replies that he is "Old enough," prompting laugther.

How well does it match the trope?
