History Recap / StarTrekVoyagerS1E3TimeAndAgain

* MySignificanceSenseIsTingling: Kes sleeps through the shockwave, then [[CatapultNightmare abruptly sits up in bed]] like she felt a great disturbance in subspace, as if millions of voices cried out in terror and were suddenly silenced by a planet-wide polaric ion discharge. In the rest timeline, she remembers this happening, but the planet is now normal.

* BookEnds: The episode starts and ends with the same scene of Tom trying to convince Harry to go on a double date with the Delaney Twins. In the second scene, the explosion never occurs and Janeway continues on her journey without stopping at the planet, as it would violate the PrimeDirective.

* TheExtremistWasRight: While their tactics are something less than diplomatic, the anti-polaric group is trying to ''prevent'' a disaster that Janeway and Paris know from being time travelers is already destined to happen.

* FalseReassurance: The Doctor sardonically tells Kes she has the healthiest Ocampa brain he's ever seen. Of course it's the [[OverlyNarrowSuperlative only Ocampa brain he's ever seen]].
* FictionalGenevaConventions: Tuvok mentions the Polaric Test Ban Treaty, which prohibits research into polaric ion energy by the Alpha and Beta Quadrant powers due to its destructive potential.

* HeroicSacrifice: Tom Paris [[TakingTheBullet jumped in front of Latika]] to protect him. Notable as Paris knew these people had less than an hour to live.

* MyGirlBackHome: Kim wants to remain faithful to his girl back home, Libby.
* MySignificanceSenseIsTingling: Kes sleeps through the shockwave, then [[CatapultNightmare abruptly sits up in bed]] like she felt a great disturbance in subspace, as if millions of voices cried out in terror and were suddenly silenced by a planet-wide polaric ion discharge.

* YouWatchTooMuchX: Latika screams in terror when Tom and Janeway appear, and screams that they must be demons because they popped out of thin air. A nearby policeman tells him that he "Reads too many of those ''Darkstorm'' tales."

The protestors are planning to infiltrate the local power plant. Makull threatens to kill Latika if Janeway won't help them talk their way inside, but she sabotages their efforts, resulting in a shootout with the guards. The protestors try to shoot Latika, but Paris takes the shot to save him. Inside, Janeway manages to hold Makull and gunpoint and explains that blowing up the plant will destroy the world, but Makull insists that he's not there to blow up the plant. Meanwhile, Kes leads the rescue team into the factory and helps them locate the corridor where Janeway died. They start to open up another gate to rescue her.

On ''Voyager'', Chakotay leads an effort to rescue the castaways. They work on a device that will help reconnect them to their own time. Kes insists on joining the away team. While on the planet, Kes hears Janeway speak momentarily, detecting her across time. A day previously, the two protestors haul in Latika, whom they caught skulking around, and force him to join their other two captives. Under questioning, Janeway comes clean about being from the future and explains the impending calamity, but Makull doesn't believe her. Chakotay manages to send a brief message to Janeway through her combadge, which Makull simply confiscates. The protestors take a particle injector and order their three hostages to move out. When Chakotay's team manages to create a time bridge to rescue his cremates, they've already left.

* WalkAndTalk: The activists with their guns on Janeway and Paris march them to the power plant slowly enough that they're able to puzzle out their situation a bit along the way.

* AbsenceMakesTheHeartGoYonder: Not for stalwart Harry Kim, who would prefer to be faithful to [[MyGirlBackHome Libby]].

* CallBack
** To TNG's ''[[Recap/StarTrekTheNextGenerationS3E15YesterdaysEnterprise Yesterday's Enterprise]]'' when [[RippleEffectProofMemory Kes checks with the bridge that everything is all right]] at the end of the episode, just as Guinan did.
** To the ''[[RecycledPremise previous episode]]'' with [[TimeyWimeyBall an event that precedes its cause]].

* ChangedMyJumper: Realizing they stick out in their Starfleet uniforms, the first thing Janeway and Tom do is ask for directions to a clothing store.

* FalseReassurance: The Doctor tells Kes she has the healthiest Ocampa brain he's ever seen. Of course it's the [[OverlyNarrowSuperlative only Ocampa brain he's ever seen]].

* ImproperlyPlacedFirearms: The anti-polaric activists use Detonics Pocket 9's and the security forces use Calico M950's -- both firearms with a 'futuristic' look.

On the planet, Paris and Janeway work to fit in, but Latika, a young boy who saw them appear, is convinced that they're demons and starts spying on them. Paris locates a working timepiece and figures out that the world-ending catastrophe will happen within a day. They start investigating the local polaric field and trace it to a power planet, where a protest is going on. Janeway gets injured during the brawl and taken to the home of a protest leader, Makull, to recuperate. However, Her and Paris's story quickly breaks down under his questions, and he and his associate Ny Terla hold them at gunpoint, believing them to be spies.

On Voyager, Chakotay leads an effort to rescue the castaways. They work on a device that will help reconnect them to their own time. Kes insists on joining the away team. While there, she hears Janeway speak momentarily, detecting her across time. A day previously, the two protestors haul in Latika, who they caught skulking around, and force him to join their other two captives. Under questioning, Janeway comes clean about being from the future and explains the impending calamity, but Mukall doesn't believe her. Chakotay manages to send a brief message to Janeway through her combadge, which Mukall has confiscated. The protestors take a particle injector and order their three hostages to move out. When Chakotay's team manages to create a bridge between the two times, it's too late.

The protestors are planning to infiltrate the local power plant. Mukall threatens Latika if Janeway won't help them talk their way inside, but she sabotages their efforts, resulting in a shootout with the guards. The protestors try to shoot Latika, but Paris takes the shot to save him. Inside, Janeway manages to hold Mukall and gunpoint and explains that his attack on the power plant will destroy the world, but Mukall insists that he's not there to blow
up the plant. Meanwhile, Kes leads the rescue team into the factory and helps them locate the corridor where she died. They start to open up another gate to rescue her.

On the other side of time, Janeway sees the bright light of the gate opening and, seeing that it is almost the moment of the world-ending explosion, realizes that it's the rescue attempt itself that caused the calamity. She uses her phaser to close the gate before it can destroy everything. In doing so, she averts the disaster that set everything in motion, and time resets to just before the explosion. No one has any memory of the events that transpired throughout the episode, though Kes seems unusually relieved to be told that the nearby M-class planet is teeming with life.

* MinimalistCast: For most of the planet scenes, there are no extras around whatsoever, despite the very lengthy talk and walk scene. Also, the power plant has the two guards at the gate and no other employees appear at all.

* SeriesContinuityError: In what may be a sign that this episode was written with the intention of airing before the previous episode, "Parallax", the Doctor suddenly becomes totally ignorant of who Kes and Neelix are, or of the fact that there are Maquis on-board, despite the fact that he had interacted with both Kes and Chakotay, while also treating Carey for an injury inflicted by a Maquis crewmember, in the previous episode.
** PoorCommunicationKills: It's not that the Doctor doesn't know ''who'' they are, it's that he doesn't know that Kes, Neelix, Chakotay and the other Maquis are not part of Voyager's original crew because no-one has told him, given that the Doctor is 'switched off' when not being used for medical purposes, and he's not hungry for gossip as in later seasons.

''Voyager'' is traveling on its [[TheHomewardJourney long journey home]] when a shockwave from a nearby planet rocks the ship. A massive explosion, caused by a volatile power source called polaric ion energy, has destroyed an entire pre-warp civilisation. When an away team is sent down to investigate, Paris and Janeway get themselves trapped in a temporal fracture, sending them back in time to the day before the disaster.

* WhatTheHellHero: Tom Paris calls out Janeway on intentionally letting an entire planet get wiped out for the sake of upholding the Prime Directive, and points out that her argument about "not knowing the consequences of intervening" is pretty absurd considering they really couldn't get any worse than the known consequences of ''not'' intervening. As usually happens when someone makes a sensible argument on ''Voyager'', Janeway pulls rank on him and dismisses his suggestion without further comment.

* EatsBabies: Invoked. A local boy starts harassing Janeway and Paris, fearing they might be demons. When he states that there only four people coming from Kalto Province, three quarters of them were a couple and their child, so if they were them, they'd have a child with them. Exasperated, Tom says they've eaten the child; they really are demons, and that it's been a while since lunch, causing the youth to flee in terror.

* TheCasanova: Tom tries to get Harry to go on a double-date with the Delaney twins. When Harry says he has a girl back home, Tom casually admits to having five, and points out that the rest of the crew will start pairing up soon, so they need to get in first.

* EatsBabies: Invoked. A local boy starts harassing Janeway and Paris, fearing they might be demons. When he states that there only 4 people coming from Kalto Province, three quarters of them were a couple and their baby, so if they were them, they'd have a baby with them. Exasperated, Tom says they've eaten the child; they really are demons, and that it's been a while since lunch, causing the youth to flee in terror.
