Fury ( episode ) Kes returns , seeking revenge on both " Voyager " and Janeway . Summary . Teaser . In her ready room , Janeway is grilling Tuvok about a secret he has been keeping . She walks over to the replicator and produces a birthday cake as it turns out to be Tuvok ' s birthday . Tuvok reluctantly blows out the candle on the cake , claiming it was a " " fire hazard " " . Commander Chakotay calls Janeway to the bridge . The has received a distress call from a small ship . Sensor s reveal the ship has one Ocampa n lifeform on board . It is an aged Kes , now around six or seven years old and appearing frail and weak , asking for permission to beam aboard . When Captain Janeway questions her motives , Kes cuts the com channel . Immediately after , her ship is on a collision course with " Voyager " and just before it is destroyed , Kes manages to transport herself on board . Act One . Furiously , she makes her way to engineering , giving off high levels of neurogenic energy that destroy the sections she is walking through . She does not respond to any hails from the captain and even force field s cannot hold her back . All attempts by Ayala and a security guard to stop her fail and she finally reaches engineering , making her way to the warp core . While she is holding on to the core , she kills B ' Elanna Torres with an energy pulse emitted from it . Holding on ever stronger to the warp core , she lights up and disappears . She somehow uses the warp core to travel back in time to 2371 , 56 days and 17 hours after " Voyager " had become trapped in the Delta Quadrant . In 2371 , there are now two Keses : the one that belongs to 2371 and the one that has traveled back in time to 2371 . Materializing right next to the warp core , she transforms herself into a duplicate of the young Kes . The Torres of 2371 asks Kes if she would like to stay and observe a warp core assembly , but she tells the chief engineer she is needed in sickbay . Upon arriving there , Kes starts fiddling around with some of The Doctor ' s medical instruments . The Doctor is annoying her with his questions about what name to pick for himself . Barely listening to him , she picks up a hypospray and rushes out of sickbay . In the airponics bay , the real Kes who belongs to the timeline , is attacked from behind by the " old " Kes , sedated and hidden , so that there are not two Keses walking around the ship . Act Two . In the mess hall , Tom Paris and Neelix are chatting about some unique names he could use for a cheeseburger he has made , when Kes walks in and asks Neelix for some coffee that she wants to bring for the captain . She is a bit grumpy and distanced , unable to laugh at Neelix ' s jokes as she used to . She grabs a canister with coffee and goes to the captain ' s ready room . Janeway and Chakotay are there discussing the Vidiian s , with the captain and first officer discussing the plight of the imperiled species and the lengths they go to to harvest organs . Chakotay wonders what Human s would do if they were faced with similar circumstances . Kes arrives shortly after and she spills some coffee on the captain ' s desk , supposedly by accident , and when the captain is called to the bridge , Kes accesses Janeway ' s computer terminal . When Kes leaves the ready room , Tuvok , who is standing on the bridge at the science station with Janeway and Ensign Wildman , looks at her from afar as if he sensed something . Later , during a staff meeting in " Voyager " s briefing room which is all about finding a way to evade the Vidiians and navigate the ship through a region of space densely packed with subspace vacuole s , Tuvok suggests taking the " Delta Flyer " with its advanced sensors to navigate through the region . This comes as a big surprise to everyone , because they have never heard of a " Delta Flyer " . Tuvok apologizes , believing that he must have been thinking of another starship . Paris finds Kes sitting in a shuttle programming a trajectory to and asks her if she is homesick . She claims she ' s not . She ' s " studying " the helm configuration and asks Paris to teach her how to fly . He agrees to give her some tutorials in the holodeck in an old Class 1 shuttle . While entering a turbolift Tuvok sees Naomi Wildman . He follows the hallucination to Cargo Bay 2 where he sees the alcoves with all the rescued former Borg , Azan , Rebi , and Seven of Nine , regenerating . Then he snaps back to reality when Lieutenant Carey , working at a console , asks him if he is all right . Kes walks into her quarters to find that Neelix has prepared one of her favorite meals for her , leaving her a message that says how much he misses her . Suddenly , she becomes irrationally angry and furious , throwing everything off the table and yelling at the computer to turn off the music . She then asks it to open an encrypted channel and direct the signal to the Vidiians whom she informs about Captain Janeway ' s plan to evade their vessels . She offers to send them tactical data on shields , weapons and anything else they need to take " Voyager " . In return , she asks for safe passage back to Ocampa for herself and one other person . When asked by the Vidiian why she is abandoning her crew , she coldly states that they are not her crew , for they abandoned her long ago . Act Three . Kes is back in airponics checking up on her younger self whom she apparently has hidden in one of the drawers . After finding everything okay she heads over to a computer console to ascertain " Voyager " s tactical information where she bypasses the command authorization by using her powers . In the meantime , Tuvok discusses his hallucinations with the captain in her quarters . He informs her of having run into a half - Human , half - Ktarian girl named Naomi Wildman in the turbolift and also of his encounter with a woman and several children with cybernetic implants . He cannot explain what is happening to him . Even though he has had hallucinations before , it has always been in the context of deep meditation . However , these are specific , evoking a sense of anticipation . He is concerned because Vulcan s generally do not have premonitions . Janeway instructs the computer to run a continuous scan around Tuvok so they can monitor what is happening to him next time he has another one of his visions . Then Chakotay calls them to the bridge to inform them they have reached the subspace vacuoles . " Voyager " is programmed to fly at warp and make course corrections according to previously made scans of this region . This is going to take 3 hours 12 minutes and 11 seconds according to Tom Paris with 216 course changes . After the first course correction the captain leaves for sickbay to ask about Ensign Wildman . Then Tuvok has another hallucination . This time it is a sensor reading of a vessel on a collision course , which no one else is seeing . Tuvok asks to be relieved of duty . The Doctor , albeit reluctantly because of doctor - patient confidentiality , confirms Ensign Wildman ' s pregnancy which is producing a half - Ktarian female offspring , Janeway realizes that everything Tuvok said is true and that there is something very strange going on . Tuvok ' s hallucinations become stronger and more frequent until he finally breaks down in engineering and goes into synaptic shock . Examining the proximity scan of Tuvok at the time where he broke down in engineering , Janeway discovers a surge in tachyon particles , indicating temporal distortion s and thus probably time travel . While nervous about these findings and researching the occurrence of tachyon particles elsewhere on the ship , " Voyager " suddenly finds itself under attack by the Vidiians . Act Four . The Vidiians keep matching " Voyager " s shield frequencies . Then the Vidiian ship attaches itself to " Voyager " s hull , trying to access the ship directly . Janeway asks for the neural agent The Doctor has been developing and asks him to release it in the sections where the Vidiians have cut a hole through the hull , but much to their horror they find that environmental control s are not responding ; they have been locked out of that system , all command relays have been fused and the Vidiians are about to board " Voyager " . That is when Janeway realizes that the Vidiians knew where to find them all along : they knew their shield frequencies and which systems to target . Someone told them . An electromagnetic fluctuation that could indicate a transmission is detected in the airponics bay . Bioreadings pick up two Keses . Janeway makes her way down there , where Kes is about to unsuccessfully initiate a site - to - site transport . Janeway confronts her in the airponics bay . When asked why she is helping the Vidiians , Kes tells her that she is from a future she is hoping to change , and uses her telekinetic powers to throw Janeway around the bay and out of her way . She says that she won ' t let them hurt her again by taking her from Ocampa , her home . She claims to have been a prisoner on this ship , a child who was corrupted by their ideas of exploration and discovery . She tells her that in three years she will leave " Voyager " in search of higher things because Janeway encouraged her to develop her mental abilities ; something she was not ready for . She couldn ' t control what she found . It scared her , and she felt she had nowhere to go . She thought of returning home to Ocampa , but knew that the people on her home world would be frightened by her mental abilities and not accept her . But they will accept the younger Kes , the one she is holding and wanting to transport over to the Vidiian ship . All attempts by Janeway to make her understand reason fail , and Kes becomes more and more furious until finally Janeway has no choice but to set her phaser to kill Kes . Meanwhile , " Voyager " manages to break free of the Vidiian ship and drive them off . Act Five . Later , in engineering , Tuvok , who is standing in front of the warp core , says that Kes was standing exactly here during his last premonition , where she appeared older , faceless , tired . They note that tachyons are concentrated in the warp core and that it was possible that she used the core to travel back in time . If that is true , then she will need it again but unfortunately , they don ' t know when that will be and yet they have to be ready for it . When young Kes regains consciousness , Captain Janeway tells her in confidence what has happened and that they will need her help to prevent it from happening again . Five years later , " Voyager " receives a distress call from a small ship . Sensors reveal the ship has one Ocampan lifeform on board . It is an aged Kes , who appears frail and weak , asking for permission to beam aboard . When she hears that , Janeway , who admits she had almost forgotten the incident , is immediately alerted and knows what to do . She raises shields and goes to red alert and orders the emergency evacuation of deck eleven . Kes ' ship is on a collision course with " Voyager " and just before it crashes , Kes beams herself on board . Furious , she makes her way to engineering , giving off high levels of neurogenic energy that destroy the sections of the corridor she is walking through . She does not respond to any hail s and even force fields cannot hold her back . On the bridge , Janeway orders the shutdown of the warp core and signals to Tuvok to be ready and follow her . In engineering , Janeway plays the hologram Kes had recorded before leaving " Voyager " . In that , the holographic recording of Kes reminds her older self that no one forced her to do anything ; that she was the one who made the decision to leave Ocampa and also the one who made the decision to leave " Voyager " . She asks her not to take revenge and just find another way home with the captain ' s help . She asks her to try and remember who she used to be . Janeway walks in , telling her what will happen if she crosses the timeline again . She offers her to stay with them on " Voyager " but Kes says that she cannot , for she does not belong there anymore and needs to be with her own people . Suddenly she smiles , saying that she now remembers the holorecording she made years ago to remind herself of who she is . Janeway asks her whether it really matters which Kes goes home . In the transporter room , the captain and Neelix are sending Kes off . Neelix hands her a few snacks of leola root for the journey home and looks at her in reminiscence . When she asks him if he sees anyone he knows with a small smile , as she had changed a lot both inside and out , he replies that he only sees her . After Kes is beamed back to her vessel , Tuvok asks what they should tell the others . Janeway says to simply tell them that a friend got lost and they helped her find her way . With these words Janeway and Tuvok leave the transporter room and Kes ' ship sets a course for home . Memorable quotes . " " We ' ve known each other for how long ? " " " " Approximately twenty years . " " " " We ' ve served on three starships together . I was present at your daughter ' s " kolinahr " . I consider you one of my closest friends . " " " " And I regard you with the same esteem . " " " " I ' ve always been honest with you , but you ' ve been keeping something from me . " " " " I don ' t know what you mean . " " " " Don ' t you ? It took exhaustive research , sifting through teraquads of data , separating fact from rumor , but eventually I arrived at the truth . " " " " Captain ? " " " " Happy birthday . " " " " It was a fire hazard . " " " " Lieutenant Torres is dead . Kes has vanished . " " " " Identify yourself . " " " " It ' s me , Tuvok . Naomi Wildman . " " " " State your intentions ! " " " " One down , 215 to go . " " " " What do you remember ? " " " " I was in airponics , and then I felt dizzy , and then I was watching myself . " " " " Yourself ?

Out here , I get to fly a state - of - the - art ship and there ' s no admiral s in sight . " " " " Goodbye , Kes . " " " " Captain . " " " " What should we tell the others ? " " < br > " " A friend got lost . We helped her find her way . " " Background information . Apocrypha . In the novel " " - " Evolution " , it is revealed that the Kes that appeared in this episode was technically not Kes , but was actually the result of Kes merging with another Ocampan who was undergoing a complex ' pregnancy ' with a Nacene , with the Kes depicted here essentially being a manifestation of the darkness within Kes rather than Kes herself .
