Relativity (episode)
Seven of Nine is recruited by a starship from the 29th century to save Voyager from being destroyed in the past.

Summary

Teaser 

In 2371, Captain Janeway beams aboard the starship  during the final phases of the 's construction at Utopia Planitia. Admiral Patterson, who had been her calculus instructor at Starfleet Academy, is there to greet her with a pop quiz. After Janeway answers all of his questions correctly, Patterson shows her around her new ship. When they reach the bridge, Janeway starts to comment on how it is bigger than she expected. She sits in her chair briefly, then is shown her ready room. There, Janeway brings up her mission, specifically, Tuvok and her desire to bring in Thomas Paris. Back to the bridge, she begins proposing changes to Voyager already and, as she and the admiral start to get into a conversation, an ensign walks away from the helm. The ensign is a completely Human-looking Seven of Nine, avoiding eye contact.

Act One 
Seven of Nine scans the bridge and the observation lounge with a small, sleek tricorder. There, Janeway and Patterson come in, and she quickly hides her tricorder. After a brief chat, they leave, and she continues scanning, then leaves for engineering. There, she encounters Lieutenant Joe Carey, who, being friendly, questions her to get to know her. Her cover story has her not assigned to the ship, but rather Utopia Planitia. She then enters a Jefferies tube and locks it. She starts scanning again. She contacts someone, telling them that she localized the weapon's source. Opening a hatch inside the tube, she sees a strange device inside it. The people she is in contact with tell her to begin a procedure. She attempts to remove it, but cannot because the device is out of phase; she is in the wrong timeline, but her contact says it's still good they know where it is.

Meanwhile, Janeway and Patterson overhear Carey finding a malfunction in an EPS relay. Wanting to get her hands dirty, Janeway goes to the Jefferies tube, only to find it locked from the inside. Patterson and Janeway go to another deck to access the tube. Seven of Nine detects them and discontinues her procedure, waiting for beam-out. Aboard another, apparently very advanced starship, the Captain says to pull her out, even when they have trouble locking on to her, saying that if Janeway and Patterson find her, then it will contaminate the timeline. When Janeway and Patterson reach the tube, Janeway only finds a strange chroniton flux of .003 that vanishes.

On the advanced ship, Seven approaches the temporal threshold and materializes onto their ship successfully, however, she falls unconscious. One of the officers goes to check on her, but, as he had warned his captain, she is dead.

Act Two 
Since Seven is dead, the Captain orders to recruit her again. The XO, Lieutenant Ducane, orders a new time index in the Delta Quadrant, target: USS Voyager.

On a seemingly normal day in 2375, The Doctor is examining Seven of Nine for symptoms of blurry vision and dizziness, which she believes are symptoms of Albright-Salzman syndrome. The Doctor concludes that she in fact has a mild case of sensory aphasia, which he clears up. The Doctor then returns to sickbay, where he begins to find many cases of space sickness, including Janeway.

Meanwhile, Paris is walking through the corridors doing a ping pong exercise. He invites Seven to be on his team for a ping pong tournament because his other team member had come down with space sickness. She accepts and Paris continues his exercises. The tournament takes place in the mess hall against Harry Kim and B'Elanna Torres, with Neelix keeping score. Shockingly, just as Paris spikes the ping pong ball, it stops in the middle of the table in mid-air. Seven scans the table and detects a temporal anomaly. Seconds later, the ball shoots back towards Kim and Torres. Neelix jokingly still records it as a point.

Tuvok, Janeway, and Seven then find that temporal anomalies are occurring all over the ship and will soon tear the ship apart, so Seven and Torres start looking for the source of the anomalies, while the Captain tells The Doctor about them. He suspected an anomaly, with the large number of cases of space sickness he's seen. Neelix then calls The Doctor to the mess hall because Ensign Mannus is violently ill. Once there, oddly, Neelix greets him as if nothing was wrong. He asks Neelix where the medical emergency is. Neelix says that everything was fine there. At that moment, Mannus falls unconscious. The Doctor diagnoses him with space sickness then revives him. He then starts to put it all together. He checks the time in the mess hall and in sickbay. Sickbay is several minutes ahead of the mess hall. Neelix had not made his call to sickbay yet.

Chakotay reports to Janeway, who just had three day old replicated coffee. As it is apparent, the distortions are interfering with food replicators. Janeway then decides to input security measures. As Chakotay explains that turbolifts are malfunctioning and everyone is forced to use the Jefferies tubes, a temporal fracture accelerates his conversation by a few seconds.

Meanwhile, Torres and Seven found the source of the anomalies. It was coming from a device in the Jefferies tube that only Seven can see with her ocular implant. They tell the Captain, who is ready to initialize a set of force fields to counteract the anomalies. The plan fails and the hull starts to demolecularize. Just then, two men from the unknown ship beam in, giving off a similar chroniton flux from five years ago, spacedock. The captain orders all hands to abandon ship. As Seven moves to an escape pod, she sees the two men. She tells them to identify themselves. They ignore her and place a device on her which beams the three of them away. Seconds later, Voyager is split apart and explodes with almost everyone on it.

Act Three 

Captain Braxton welcomes Seven to the Federation timeship . They explain to Seven that Voyager has just exploded due to a saboteur putting a force-3 temporal disruptor on the ship. They suggest to Seven that the saboteur transported onto Voyager while Voyagers shields were down in an attack by the Kazon. Seven agrees to help them prevent Voyagers destruction. Ducane begins by testing her on all things about time, such as the Pogo paradox, when the Borg tried to prevent the Federation from ever existing, incidentally creating it. Then, she goes to a holodeck to view the device in its location on Voyager with Braxton. Braxton unexpectedly orders her to avoid contact with Janeway if at all possible, for she has made more temporal violations than anyone in history and sticks her nose where it doesn't belong: hence he calls it the Janeway Factor, due to which he had to fix up three major temporal incursions. He also mentions the timeframe he was stuck in for thirty years. Ducane finally uses a technology to hide her Borg implants and she's ready.

In 2372, Voyager is under attack by the Kazon when Seven of Nine beams aboard Voyager. She starts scanning for the weapon immediately.

Act Four 
The crew is focused on the attack when Harry Kim detects a 0.003 chroniton flux. They rule out the Kazon's weapons as the cause, and Janeway recognizes the reading from Voyager in drydock (as she did over 2 years later). She studies it as the battle subsides, the Kazon lead ship having been disabled, and the ship escapes. Janeway remembers the last time she saw the chroniton reading and places a force field around the area. Like her 2375 counterpart, Janeway and Tuvok both go to where Seven is; however, this time the force fields isolate Seven from her 29th century colleagues. Unable to receive instructions, Seven is trapped in the corridor and Janeway finds her. On the timeship, Ducane continues to try to pull her out, but the force field continues to interfere with the transport and communications. 

Janeway demands she explain who she is, and Seven initially tries to avoid telling Janeway the truth, due to the Temporal Prime Directive, as Braxton listens in. Unfortunately, Tuvok detects Seven's hidden Borg implants so Janeway orders a search for any nearby vessels and is even more concerned. Seven insists there are none and, disregarding the Temporal Prime Directive, gives up and tells Janeway the truth. Seven convinces Janeway to free her to help prevent the destruction of Voyager in 3 years, 6 months and 2 days. In the 29th century aboard the Relativity, a crew member utters the Latin phrase , which literally translates as time flies. 

Seven and Janeway quickly go to the Jefferies tube where the weapon should be. Janeway, Tuvok, and Seven enter and find a man trying to place the disruptor in the tube. It turns out to be an older Captain Braxton.

Act Five 
The older Braxton quickly arms his device and threatens to activate it unless they lower their phasers. They do so, and then soon the younger Braxton calls in and is extremely surprised to hear who it is. The saboteur Braxton explains that this will complete "our" mission. He had undergone a temporal psychosis, having lost his rank which he blames on Voyager. He tells his "younger" self that once Voyager is obliterated, he will heal. The Braxton on the Relativity is determined to bring his older self into custody, telling Ducane to beam him aboard, but the older Braxton had activated a dispersal node to avoid beaming. Ducane then takes it upon himself to relieve his captain, placing him under arrest for crimes "he is going to commit."

Just as Seven of Nine is about to capture the older Braxton, he beams off Voyager. Seven then transports to where Braxton beamed to: back to 2371. Back during Janeway's first tour of Voyager with Admiral Patterson, they walk down a corridor as Seven and Braxton come running through. Seven shoots at Braxton, but misses. Seven starts to suffer from temporal psychosis and starts to drift out of consciousness. Due to Janeway's quick order to bring up force fields, Braxton is contained, but he then beams himself to 2375. Seven calls to be transported there.

In the mess hall, the ping pong tournament is occurring. Braxton suddenly runs through and Seven, almost unconscious, walks in and disables Braxton's tricorder, trapping him in 2375. He runs, but she then falls to the ground. The Seven of Nine in this timeline walks up to her counterpart, asking her to explain herself. Seven's counterpart tells the other Seven to stop Braxton because their future depends on it. After Relativity beams the incapacitated Seven away, the other Seven captures Braxton. When Janeway arrives, she realizes that she remembers him from 2372. Relativity beams Braxton away. They then beam Janeway to their ship.

Ducane starts to explain to Janeway all that had happened, quickly giving her a headache. He explained that there is a Braxton in their brig and a Braxton on their bridge. They ask Janeway to go back to 2372 to completely fix the timeline. Seven's attempts to remove the device have introduced several noticeable temporal incursions. She instigated a phaser fight at Utopia Planitia, interacted with Janeway's three years younger self and spoke to her younger self during a ping pong tournament in front of 15 crew members. By capturing Braxton before the device is planted these changes will be removed. Seven cannot do it because she might damage herself. Janeway is confused, especially with the second Seven. Ducane assures her that by the end of the day, there will be only one Seven. The Braxtons will soon be reintegrated in time for the trial. The Braxton on the bridge tells Janeway where he will be in that timeline and Janeway is transported to 2372.

Janeway is beamed aboard during the Kazon attack on Voyager. She encountered Torres en route, telling her to do what she think is right in Engineering. When she nears the corridor where Braxton will beam in, she hides from her three years younger self. Almost immediately, she finds Braxton beaming aboard. He stumbles over a wounded crewman. At that moment, Janeway walks over to him and captures him.

Back on Relativity, Ducane commends Janeway for capturing the last Braxton and making a small incursion of 0.0036. He then is ready to send Seven of Nine and Janeway back to 2375's Voyager, reintegrated with their past selves. He strictly reminds them to remember the Temporal Prime Directive: discuss your experiences with no one. Yet he tells her one thing: Braxton was right that Voyager appears on the Relativitys sensors too often and they should avoid time travel. They then beam back to the 2375 Voyager.

 Story and script 
 This was the last of five  episodes that Nick Sagan, story editor for the series' fifth season, was involved in writing. He previously worked on , , , and . In his capacity as story writer and teleplay co-writer here, Nick Sagan found this to be an enjoyable episode to write. He later reminisced, "I think that might have been the easiest one I worked on, because the goal is simply to have fun. With the others I felt a lot of different loyalties to character this, character that. For some reason that one came together very quickly, and it was such a joy to write because we were just trying to please ourselves." 
 Executive Producer Brannon Braga did a lot of uncredited rewriting on the episode. (Cinefantastique, Vol. 31, No. 11, p. 55)
 One aspect of this installment that was changed was its depiction of the Utopia Planitia Fleet Yards; the episode's script originally called for only a simple shot of a lone Voyager in drydock at Utopia Planitia. Adam "Mojo" Lebowitz noted, "One ship, one drydock, and that was it." ()

 Cast and characters 
 Not having been a science fiction fan prior to her work on , Seven of Nine actress Jeri Ryan found this time travel episode's script difficult to follow. "It was a challenge just keeping the time frames straight," she admitted. (Cinefantastique, Vol. 31, No. 11, p. 28)
 Jeri Ryan also found it humorously coincidental that, in this outing, her character wears the disguise of a Starfleet uniform, a fact the actress described as "actually very funny." She continued, "I had just done an online chat three or four days before this script came up. As they always do, one of the fans had asked me when we were going to see Seven in a Starfleet uniform, and I said, 'Well, never, because she's not Starfleet, of course.' Then bam, I get a call from wardrobe two days later saying, 'We need you to come in for a fitting because you are in a Starfleet uniform for the next episode." (Cinefantastique, Vol. 31, No. 11, pp. 28-29)
 Although Captain Braxton appeared in Star Trek: Voyager twice before, he is played by a different actor in this episode, with Bruce McGill replacing Allan G. Royal.

 Production 
 The 29th century phaser that Seven of Nine uses against Braxton is of the same type seen in possession of Henry Starling's assistant Dunbar in the third season episode  during the phaser fight outside the Griffith Observatory in Los Angeles in 1996.
 The thrombic modulator is seen again in this episode, having first been seen in  when The Doctor didn't know what it was.
 Another prop reused in this episode is the triangular device that Lieutenant Ducane places on Seven of Nine's arm before transporting her to the . It was used in  as a universal translator between one of the Sky Spirits and Chakotay.
 Even though some minor cosmetic changes were made to the Voyager sets for the fourth season (for example, the trim on the briefing room table as well as the ready room desk was changed from a gray to green), the scenes from this episode that take place prior to  show the newer set colors.
 According to the unauthorized reference book  (pp. 312 & 314), the bridge of the Relativity was a redress of the  bridge, with interior design elements from the Enterprise-E and Voyager.

 Visual effects 
 The reasoning why the Utopia Planitia Fleet Yards was depicted as more extensive than the script suggested was that the visual effects artists from Foundation Imaging were extremely excited about visualizing the elaborate shots that open this episode. "As fans who were working on the show, we couldn't bear to be this close to seeing the shipyards and not go all the way," reflected Adam Lebowitz. "So, in our own time, we created the entire shipyard and took rough drafts of the shots we had in mind to VFX supervisor Ron Moore and producer Peter Lauritson. Luckily, they were very receptive. It may have only amounted to two shots in the final episode, but they were an absolute labor of love for all of us. The half-constructed ships looked great (thanks to the hard work of Koji Kuramura), and the image of Mars you see in the final sequence is made from a satellite photo of the real Utopia Planitia, courtesy of the folks at NASA. In fact, the whole time we were working on the episode, we thought it was a shame that the people at home would only see this stuff on blurry TV screens, and not in the high-resolution glory we had created them in." () Robert Bonchune and Lee Stringer were others at Foundation Imaging who donated personal time to realize the sequence. 
 The battle scenes between Voyager and the Kazon were stock footage of combat from earlier episodes, in the order of , , and .

 Continuity 
 This episode features the return of not only Captain Braxton, whose previous appearances were in the two-parter  and , but also Lieutenant Joe Carey, who was last seen in Season 1's . However, Carey's scenes here take place before Voyager is lost in the Delta Quadrant. He returns in , but his scenes in that episode also take place in the past. He is not seen again in the present (namely, 2378) until , in which he is killed.
 Braxton mentions that Janeway and Voyager are involved in three major "temporal events". The first ("30 years trapped in the 20th century") is clearly a reference to  while the second ("temporal inversion in the Takara sector") is a more subtle reference to . The third was never described. However, it could be the events of  and  or the series finale .
 Seven of Nine travels back in time to Voyager during a Kazon attack, though this specific event does not seem to be from a previous episode featuring the Kazon. Ducane states the stardate target for the temporal transport as 49123.5621. This would place the events as occurring between the second-season episodes  and . The conflict with the Kazon was taking place during that time.
 Braxton claims to remember being stranded in the 20th century in this episode, despite having claimed to Janeway at the conclusion of  that he "never experienced that timeline."
 In scenes set at the Utopia Planitia Fleet Yards, this episode makes several references to the events of . Notably, Janeway and Admiral Patterson discuss the whereabouts of Tuvok (undercover on Chakotay's Maquis ship), enlisting Paris, and going to the Badlands.
 In  this episode Janeway tells Admiral Patterson that she wants to enlist Tom Paris' help because his superior piloting skills can help them get through the Badlands, however in  Janeway recruits Paris to lead her to hidden Maquis bases, with her making clear during that episode that she did not expect him to pilot.
 This episode features the eighth of nine times that Kathryn Janeway's death is depicted over the course of the series. Previous episodes that depict this include , , , , , , and . On this occasion, the version of Janeway that succumbs to death is that of an alternate timeline that ultimately doesn't come to pass, and the cause of death is Voyagers destruction as a result of the temporal distortions.
 This episode features the fifth and final time that the destruction of Voyager is depicted on the series, previous occasions being , , , and . On this occasion, an alternate timeline version of Voyager is destroyed by temporal distortions.
 According to the stardates, the 2375 portions of this episode take place at about the same time as , which was originally broadcast two weeks later.
 This is the first episode to feature the actual Utopia Planitia Fleet Yards. The fleet yards were seen previously in a picture in  and as a holographic simulation in .
 The events of Star Trek: First Contact are used as an example for the Pogo paradox.
 In  there are also localized time discrepancies as time running faster or slower in specific locations from inside a room to a vast region in space.
 Captain Braxton wears a blue uniform indicating that at some point in the future the command division will switch to blue uniforms.
 Admiral Patterson is shown activating the Doctor's program during Captain Janeway's inspection tour in dry dock, however previous episodes (most notably ) firmly established the Doctor's first activation didn't occur until after Voyager arrived in the Delta Quadrant.

 Reception 
 Ultimately, Brannon Braga was extremely pleased with this installment. "Relativity' is a time travel romp," he declared. "It's an incredibly fast-paced, mind-bending, fun, time travel story. [The identity of the bomber] will be a real shocker." (Cinefantastique, Vol. 31, No. 11, p. 55)
 Nick Sagan was also satisfied with this outing, likewise finding it to be fun. He stated, "I don't think it's an episode that needs to be studied, per se, or ruminated upon, you just go with it like a rollercoaster ride." 
 The book Star Trek 101 (p. 177), by Terry J. Erdmann and Paula M. Block, lists this episode as one of the "Ten Essential Episodes" from Star Trek: Voyager.
 Among the costumes and props seen in this episode which were sold off on the It's A Wrap! sale and auction on eBay was Jay Karnes' uniform.
