Timeless ( episode ) A failed attempt to return home results in " Voyager " crash - landing on an ice world and also in the deaths of the crew , except Chakotay and Harry Kim . Now , fifteen years later , the two men , having resigned from Starfleet , attempt to alter history to save the ship from disaster before Starfleet can stop them . Summary . Teaser . " 2390 " A vast , icy landscape . Two figures materialize out of a transporter beam , shielded against the cold by cold weather suit s . Laden with heavy backpacks , they begin hiking across the landscape . On reaching a certain spot , they stop and stick a sensor device into the ice . They brush aside a patch of snow , revealing a clear layer of ice underneath . Something not of nature is clearly visible under it . One of the figures taps his chest in the same spot where a Starfleet combadge would be . Sure enough , the chirp of such is heard . The figure ' s voice reveals him to be male . His face , like that of his companion , is hidden beneath his suit ' s mask . He indicates to the other that they have arrived at their destination . Beneath the thick sheet of translucent glacial ice , unmistakable markings become visible . USS " Voyager " NCC - 74656 Act One . The other figure makes scans on a tricorder and informs the first that the fractures in the glacier the ship is entombed in are stable ; they can beam inside safely . Like the first , this one ' s voice also reveals that it is a man . The first informs a third party over his combadge that they are ready to enter . A female voice acknowledges . They beam inside . Inside " Voyager " is dark and icy . The two figures , after materializing , remove their masks . They are revealed to be " Voyager " s First Officer , Commander Chakotay and Operations Officer Ensign Harry Kim . Both appear noticeably older . Both are very grim - faced . Using wrist - borne lights to light their way , they walk slowly to a dark , dead , frosted - over wall console . Kim scrapes ice off of it , connects a portable power cell and activates it . The console comes to life . Kim accesses it and reports the extent of " Voyager " s damage : her power grid is destroyed , her bioneural gel pack s are frozen solid and six of her lowermost deck s are compacted . Chakotay muses that she must have crashed into the ice at full impulse . He asks about The Doctor , their EMH , who served as the ship ' s chief medical officer . Kim tries to access the sickbay . But the console flickers and dies , despite his attempts to keep it going , to his great frustration . They decide to split up . Kim heads for the sickbay while Chakotay goes to the bridge . Chakotay reaches the bridge . It is frosted over and dark , like every other area on the ship . He walks among frozen bodies of crewmembers , including that of " Voyager " s Captain , his commanding officer and friend , Captain Kathryn Janeway . Chakotay pauses at her corpse for a long while before continuing . He is searching for something . He finds it : the corpse of the former Borg drone Seven of Nine . He hails the third party he spoke to before , calling her " Tessa " , and informs her . He instructs her to lock on to the transporter relay he places on the corpse ' s neck and beam the cadaver to " the lab . " She acknowledges and does so . He watches grimly as the cadaver dematerializes . Kim arrives at the sickbay . He scrapes ice off a wall console here and activates it with his power cell . He taps some controls on it . The Doctor appears , and starts his standard EMH greeting . But his words trail off as he sees what has become of the sickbay . He looks around in utter , uncomprehending horror . Kim tersely greets him . The Doctor addresses him in shock as " " Ensign ! " " , but Kim tells him not to . He instructs him to don his mobile emitter . The Doctor does so and agitatedly asks him what has happened , but he tersely responds that there is no time for that . He orders The Doctor to follow him . The Doctor refuses , demanding an explanation . Chakotay enters and walks up to him . He provides him with a cryptic response : they are there to " " change history . " " Act Two . " Fifteen Years Earlier : Year 2375 " A great celebration is taking place in " Voyager " s Engineering area . Crew and officer s are gathered , clapping and cheering . Confetti falls . Chief Engineer Lieutenant B ' Elanna Torres grins hugely as she smashes a bottle of champagne against the rail surrounding the warp core . The core looks strange , as if it has been modified . Captain Janeway calls for quiet and gives a speech . She proudly introduces the modified warp core as the " quantum slipstream drive " , to cheers and applause . She speaks of the time " Voyager " has been lost in the Delta Quadrant : four years , two months , 11 days . To more cheers and applause , she then announces that " " now it is time to go home . " " The quantum slipstream drive , should it work , will accomplish this ; very much faster than warp drive , it would allow " Voyager " to cross the many tens of thousands of light year s between here and Earth in mere hours as opposed to the several decades that warp drive would take . Janeway exhorts everyone to enjoy the party , but reminds them of the final work that needs to be done ; the flight using the drive is scheduled for the next morning . Everyone mingles happily . Champagne flows . Seven of Nine , amusingly , becomes drunk from a single glass . Neelix , the Talaxian chef , gives Torres a good luck charm for the drive : a Talaxian fur fly , which he had kept hung in the engine room of his own small ship while he was a trader , before he joined " Voyager " . All enjoy themselves . But Lieutenant Tom Paris does not take part . Instead , he is seen at a console , running tests . Harry Kim , the main designer of the drive , finds him and , surprised , asks him why . Paris ' expression when he turns to face Kim is one of great worry . He gives Kim his opinion of the thing : it is an Edsel , a potential disaster . He explains that he has found a 0 . 42 phase variance in the drive ' s system ; a very small phase variance , but enough to possibly bring the flight to a catastrophic end by causing " Voyager " to get knocked out of the slipstream in mid - flight . This would almost certainly destroy her , and them with her . Kim dismisses his concerns , saying that such a small variance is probably due to a sensor glitch . But Paris will not be soothed . Kim then invites him to one of the ship ' s two holodeck s to run simulations and ease his fears . Paris agrees and they leave together . The two men run a holodeck simulation of " Voyager " with Kim at the auxiliary Tactical console , while Paris mans his conn console . They begin the simulation . At first , all goes well ; Paris engages the simulated drive , and , on the viewscreen , the view of normal space explodes into the gray , tunnel - like form of slipstream space . But then the bridge starts to vibrate as the phase variance Paris detected begins to manifest itself . It begins to increase . The vibration worsens . Kim tries stabilization measures , but none work . Hull breaches occur . Structural integrity rapidly falls and then fails ; " Voyager " is tearing apart . The slipstream starts to collapse . Paris tensely orders the computer to cease the simulation . But Kim doggedly refuses to give up ; he suggests yet another idea for stabilization , but Paris tells him it will not work . Kim tries to get the computer to run the simulation again , but Paris stops him : this is their 23rd consecutive simulation , and , like the 22 before it , it has ended in calamity . This is " not " a sensor glitch , he insists ; the others " must " be told . Kim agrees with a sad sigh . In Engineering , only the senior staff is now present . The air of joyous celebration has been replaced by somberness ; Paris and Kim have reported the results of their simulations to them . Torres cannot believe it ; she angrily protests that they have tested the drive " " molecule by molecule " " . Seven informs Paris that she wants to examine the results herself . Paris somberly invites her to do so . Chakotay , however , " has " seen the results and gives Captain Janeway , who is pacing in silence , his considered opinion : if they attempt this flight the next morning , the crew will find themselves in escape pod s that very afternoon . Tuvok opines that there is no choice but to cancel . But then Paris informs them that Kim has a suggestion . Attention turns to him as he outlines it : if a shuttlecraft were to " " ride the rapids in front of " Voyager " , so to speak , then it could map the slipstream threshold as it forms and transmit phase corrections back to " Voyager " . The corrections would compensate for the phase variance , preventing a catastrophic collapse of the slipstream . The idea is theoretically sound , but very risky ; the shuttle would only be at most a couple of seconds ahead of " Voyager " , and the auto - navigational system might not be able to make the adjustments quickly enough . But Kim , sensing the reluctance , begins a vehement plea for the idea to be tried . He points out the amount of time and effort that has been put into the project , and the decay of certain crystalline components of the drive that has already begun ; components that would take years to re - synthesize . He walks from each to each , looking into their faces hotly , proclaiming that he did not " " do all this work just to be stopped by a 0 . 42 phase variance . . . ! " " He finds himself shouting into Captain Janeway ' s face , and immediately apologizes . He begs her to let him try , confidently insisting that he will get them through the slipstream . She takes no offense , and orders him to submit a flight plan to her within the hour ; she will let them know her decision . Extremely pleased , Kim acknowledges . The officers disperse . Janeway and Chakotay have dinner in the former ' s quarters . As they sit at the table , with Intermezzo op . 117 no . 1 by Brahms playing in the background , she makes her decision known to Chakotay ; she has approved the attempt . Chakotay acknowledges , but voices his disagreement . He holds up a PADD containing Kim ' s flight plan . He has looked at it ; the theory is sound , but there are simply too many variables . But Janeway responds that they have waited long enough to get home ; they may never have this chance again . With a smile , Chakotay assures her of his support of her , though he does not agree with her decision . He sets the PADD down . 2390 The same PADD , frost - covered and long inoperative , is seen on the floor of " Voyager " s frozen , entombed wreckage . Act Three . 2390 Kim , Chakotay , and The Doctor are on the " Delta Flyer " , a unique shuttlecraft " Voyager " had built . They fill The Doctor in . It is fifteen years after the attempted slipstream flight . They are in the Takara sector , just outside the Alpha Quadrant . The rest of the crew is dead ; " Voyager " crashed into the ice planet , killing all aboard . The Doctor recalls that Kim and Chakotay were on the " Delta Flyer " at the time ; they had been the ones mapping the slipstream and sending phase corrections to " Voyager " . Kim bitterly confirms this , commenting that they indeed made it back to Earth , with the only cost being the death of all whom they cared about . They further inform The Doctor that their finding of " Voyager " s grave is not a Starfleet - sanctioned endeavor . The service ended its search for " Voyager " nine years ago ; they continued on their own . Chakotay explains his comment to him in the remains of " Voyager " s sickbay : they are embarked on an attempt to change history , preventing " Voyager " s destruction from ever occurring . Stone - faced , his bitterness extreme , Kim elucidates : the blame for " Voyager " s destruction rests squarely on his shoulders . During the flight , he , as planned and agreed , sent phase corrections back to " Voyager " to compensate for the phase variance . But his corrections proved to be wrong ; instead , they " increased " the variance , so much so that the disaster he was trying to prevent was immediately precipitated . " Voyager " was knocked out of the slipstream and the crew was sent " " to an icy death " " . However , having fifteen years to think about his mistake , he has gone over the phase calculations from that day and has come up with a set of " new " corrections . The plan is to send the corrections back through time to " Voyager " , so that she actually makes it through and back to Earth instead of being destroyed . They intend to use three things , two of which they need The Doctor and Seven of Nine ' s corpse for , which is why they found and reactivated him , and found and retrieved the corpse . The first thing is a device they stole from Starfleet authorities : a Borg temporal transmitter , salvaged by Starfleet from the wreck of a Borg cube . The Doctor ' s job is to extract the other two items from Seven ' s cadaver : her interplexing beacon and her chronometric node . The final translink frequency registered by the interplexing beacon at the time of Seven ' s death will tell them exactly where she , and hence , " Voyager " , was before the catastrophe . The chronometric node will tell her actual time of death , when her Borg implants disengaged from her organic systems . A young woman then enters . This is the third party Chakotay was talking to . She alerts Chakotay of a Federation starship fast approaching . She informs them of measures she has taken to delay it from finding them , but warns that they will not work for long . They have six hours at most . At first , The Doctor is confused by this . But then he suddenly realizes what she means : they are , in fact , fugitives . Kim confirms it , listing the charges their plan has brought on their heads : high treason and conspiracy to violate the Temporal Prime Directive . Then Chakotay instructs him to begin work . He tells the woman to get ready to beam back down to " Voyager " s remains with him , to retrieve the ship ' s sensor logs . He then leaves to get himself ready . The woman smiles and introduces herself to The Doctor as Tessa Omond . Kim informs him that she is Chakotay ' s lover . She explains that she is there to help them carry out their plan . Chakotay returns for her , and they leave together . Returning to " Voyager " s bridge , Chakotay accesses the computer using his old first officer ' s command codes and begins downloading the sensor logs . As he sits in the first officer ' s seat next to the captain ' s , his pain of loss is evident . It is exacerbated when he finds a still - active file . It turns out to be Captain Janeway ' s last log entry , in which she states for the record , should the flight end in disaster , that the crew acted with " " distinction and valor " . " Tessa , seeing his pain , immediately comforts him , reminding him that if they are successful , Janeway and everyone else will be alive and well . Chakotay does indeed take comfort in this . But then another thought occurs to him : Tessa . If he is successful , he will lose her ; they will never have met . This , despite his intense desire to have " Voyager " and her crew , his friends , restored , makes him pause : can he give her up , even though it means he will get them back ? He takes her hands in his and asks her if she is sure she wants to do this , given what it will mean for the two of them . Her answer , however , settles the question : no matter how happy he is with her , his heart is , and would always be , on " Voyager " . She loves him enough to put his happiness first and help him fulfill his heart ' s desire and get them back , even if it erases what they have together . He accepts this gladly . Aboard the " Delta Flyer " , The Doctor works as Kim records a message to someone . The Doctor calls him to assist him . As they work , The Doctor asks him about his and Chakotay ' s homecoming . His extreme bitterness is made evident again as he recalls the reception they got : parades , antimatter fireworks , serenades by a Vulcan children ' s choir , speeches , and medals . The Doctor jokes that at least he was not buried under ice . This earns him a deathly glare from Kim , who responds coldly that he wished that he " had " been , many times . The Doctor sympathizes with him . Kim then , with intense sarcasm , recalls the therapy sessions he was forced to endure ; these were supposed to help him get over his survivor ' s guilt . He recalls that he signed onto the first deep space vessel he could and worked manically at finding where " Voyager " had crashed , until Starfleet , after four years of searching , called off the search , citing ' low probability of success ' . He begged them to continue , but they refused . So , he and Chakotay resigned their commission s , devised their plan and enacted it , stealing the " Delta Flyer " to do so . The Doctor succeeds in extracting the interplexing beacon from Seven ' s cadaver and reads out the interlink frequency . Kim encodes it into the Borg temporal transmitter . But The Doctor then cautiously asks him a question : is he sure about this course of action ? Suppose it causes a timeline in which things are worse ? But Kim ' s response is a look as deathly as his first , and a harsh reply that the only reason this timeline exists is because of his error . " " The crew trusted me and I let them down ! " " he spits . Then the computer sounds an alarm , and announces a warning of a vessel approaching . Kim checks the scanners and sees that it is the Starfleet vessel . He hails Chakotay and Tessa and alerts them . They acknowledge and prepare to return immediately . Kim then turns his attention back to The Doctor . He has a question of his own : given the criminal nature of their action , does he want to be a part of it ? If not , then Kim will take him off - line , not as a punishment or sanction , but as a friend , keeping him from being involved in something he is against . The Doctor considers and agrees to help willingly : he wants " Voyager " back as much as they do . Kim smiles and pats him on the shoulder . Act Four . 2375 Aboard " Voyager " , all is in readiness for the slipstream . Janeway records a log entry in which she states for the record , should the attempt end in disaster , that the crew acted with distinction and valor . Aboard the " Delta Flyer " , some distance ahead of " Voyager " , Commander Chakotay and Ensign Kim are also ready . After a pre - flight checklist , a telemetry link is established between the two vessels . Janeway gives the order to begin . 2390 The Federation starship arrives and closes on the " Flyer " . It is a starship . The " Flyer " flees at top speed , and the ship pursues them . Chakotay and Tessa pilot the " Flyer " , while Kim works in the lab with The Doctor to send the new phase corrections . The Federation ship hails . Chakotay answers . The captain appears on the small viewscreen . It is none other than Geordi La Forge , previously the chief engineer of the . He identifies himself , and his ship as the and calmly instructs them to stand down . Chakotay and Tessa refuse . La Forge then presents to them a deal offered by the Federation Council : if they stand down and return the temporal transmitter , the charge of conspiracy will be dropped . Chakotay and Tessa reject the offer . La Forge understands , admitting he would likely be attempting the same thing in Chakotay ' s position . But he is a Starfleet captain , and as such , his duty is to try to stop them . Chakotay understands this . They genuinely wish each other luck and end the communication . Tessa reports the " Challenger " is targeting the " Flyer " s engine s and Chakotay orders deflector shield s raised and weapons readied . 2375 On " Voyager " s bridge , Captain Janeway hails the " Delta Flyer " and orders Chakotay and Kim to prepare for engagement of the slipstream drive . They acknowledge . Janeway orders Paris to engage the drive . Paris counts down . At zero , he engages the drive . Normal space explodes into a slipstream tunnel as the two ships enter slipstream space . They are on their way . 2390 The " Flyer " is hammered by the " Challenger " s weapons . Chakotay fires back , but of course , the shuttle ' s weapons have no effect against the starship ' s shields . In the lab , The Doctor quickly works to extract Seven ' s chronometric node from her cadaver , to give Kim the needed time index to send new phase corrections to . 2375 On " Voyager " s bridge , Seven of Nine , at the auxiliary tactical console , detects the phase variance . Ensign Kim , on the " Delta Flyer " , quickly calculates the compensatory corrections to send back to Paris at the conn console . He sends the corrections . Paris inputs them . The variance decreases . All seems to be going well . But then Seven reports the variance is increasing again . The increase is now more rapid than before . " Voyager " is shaken and begins to vibrate . Janeway hails Kim for an explanation . Kim becomes fearful . He is at a complete loss ; the corrections should be working , he insists . He begins to quickly review them , fighting to control his fear . Then the com link between the ships fails , followed by the telemetry link . Paris reports tensely that the slipstream is destabilizing . Janeway orders him to shut the drive down . Paris tries to do so , but fails . 2390 The Doctor succeeds in extracting the needed time index from Seven ' s chronometric node . He reads it out to Kim , who quickly inputs it into the transmitter . He calls up the new corrections on the computer , interfaces the computer with the transmitter , and activates the transmitter , confidently telling The Doctor that this time , he will be successful . 2375 Seven of Nine suddenly looks perturbed . She reports to Janeway that she is receiving new phase corrections , even though the com link is down . Janeway surmises that Ensign Kim must have found a way to access her Borg implants to send the corrections . She orders them used . Seven does so . But they do not work ; instead the variance increases even more rapidly . All hell breaks loose . Paris reports the hull is buckling . Janeway orders deflector shields at maximum . She orders Paris to hold her steady . He tries , but fails . The ship explodes back into normal space . Amid the alarms , Paris shouts that inertial damper s are offline . There is no sign of the " Flyer " . Aboard the " Flyer " , still in the slipstream , Kim is shocked and horrified to see what has happened . He tells Chakotay to alter course to return to where " Voyager " was thrown out . But Chakotay tells him that that the " Flyer " would not survive falling out , even if " Voyager " did . Panicked , Kim insists , but Chakotay sternly tells him they have no choice . Kim sinks to the floor , as the full enormity of his failure starts to sink in . " Voyager " spins and careens , completely out of control . Paris informs Janeway that they are but a few parsec s from the Alpha Quadrant . Tuvok reports extensive hull breaches ; if they do not land immediately , " Voyager " will be torn apart . Paris then reports a planet nearby , Class L , covered with snow and ice . Janeway orders him to attempt to land . " Voyager " enters the planet ' s atmosphere , but fails to slow down and approaches the surface at full impulse . Janeway orders full reverse thrusters , but this avails them naught . She orders all hands to brace for impact . " Voyager " crashes belly - first into the solid , icy surface of the planet at high speed . The ship careens violently along the surface with one of the warp nacelles being destroyed upon impact with a patch of rocky terrain . Without inertial dampers , the crew of " Voyager " are killed immediately . Act Five . 2390 On the " Flyer " , Kim is shocked and very much dismayed to find that nothing has changed . If " Voyager " had been saved , then this entire timeline would have been erased , and they would not be there still trying to save her . His new corrections did not work . He checks the equipment , and hails Chakotay , informing him of the failure . The " Flyer " s engines fail . The " Challenger " catches it in a tractor beam . Chakotay suggests a dangerous method of escape : sending a plasma surge through the beam to break its grip on them . Tessa confirms that this can be done , but warns him that their heavily damaged EPS relays might cause their warp core to destabilize , destroying them . Chakotay gently tells her she can leave and beam to the " Challenger " if she so desires , but she refuses with an equally gentle smile . He returns it and hails Kim , informing him that they have a few more minutes . In the lab , Kim feverishly checks his calculations , but cannot see why they did not work . The Flyer escapes from the tractor beam but , as Tessa warned , the warp core begins to destabilize . Chakotay hails Kim and alerts him that they have three minutes until they are destroyed . Kim begins to panic . He checks and rechecks his calculations , but to no avail ; he simply cannot find the reason why they failed . The Doctor sternly tells him to keep trying . He does for a few seconds more , but gets nowhere . He falls apart . The fifteen years of guilt and self - loathing he has been carrying suddenly boil over in a tide . He steps away , his back to The Doctor , screaming , anguished : " " I killed them ! They trusted me and I KILLED THEM ! " " The Doctor becomes furious . He spins him around to face him and shouts at him into his face to control himself and stop wallowing in self - pity . Kim hysterically tells him he is repeating history , destroying " Voyager " once again . The Doctor sternly retorts that he , Kim , is the only one who can change history to save her and the crew . Kim steps away from him , tearfully insisting that it is impossible . But then The Doctor , countering that he had merely said that he couldn ' t keep the ship in the slipstream , gives him an idea that , with all his guilt , he had not even considered : while he must accept that he was unable to get " Voyager " home , could he not send them a warning to stop the flight or not attempt it at all ? Kim seizes upon this : he could send a set of calculations that would cause the slipstream to harmlessly dissipate , depositing them back into normal space and shutting down the drive . Reinvigorated by the knowledge that he could still save the ship , he rushes back to the equipment and begins making the calculations , as the computer counts down the final 60 seconds before the warp core breach es . Chakotay asks Tessa if the core can be ejected . She responds no . Captain La Forge hails them . The " Challenger " s sensors have detected the imminent core breach ; he offers to beam all of them off . Chakotay politely thanks him , but refuses and suggests he move his ship a safe distance away . Kim completes the calculations . But then he notices with horror the transmitter ' s power source is nearly depleted ; the transmitter is shutting down . He looks desperately for an alternative and finds one : The Doctor ' s mobile emitter . The Doctor gladly surrenders it . He and Kim exchange comradely smiles and pats on the shoulder , then he dematerializes . Kim attaches the emitter to the transmitter , informing Chakotay that he is giving it one more try . The time runs down . Chakotay and Tessa , in the final ten seconds , hold hands . Kim works feverishly . At the very last second , he succeeds in transmitting the calculations . He screams an elated , victorious " " YES ! " " just before the flyer explodes , killing them . 2375 Seven of Nine suddenly looks perturbed . She reports to Janeway that she is receiving new phase corrections , even though the com link is down . Janeway surmises that Ensign Kim must have found a way to access her Borg implants to send the corrections . She orders them used . The corrections cause the drive to shut down . Paris reports the slipstream is dissipating . Both " Voyager " and the " Flyer " emerge from slipstream space back into normal space , unharmed . Communications between the two ships comes back online . Ensign Kim hails " Voyager " , confused , and asks what happened . Captain Janeway , looking very displeased , tells him that he made a mistake : the phase corrections , which he sent to Seven shut the drive down . This confuses Kim even more ; he responds that he sent no corrections to Seven . This stuns Janeway and the bridge crew . She informs him that Seven received a set of corrections through her implants . " " It wasn ' t you ? " " she asks . He repeats that it was not . Janeway and the bridge officers look at each other , dumbfounded . Janeway notes in her log that she has ordered the quantum slipstream drive dismantled . A disappointed Chief Engineer Torres is seen overseeing this . But Janeway also notes that the little time they spent in the slipstream shaved a solid ten years off their journey . Now , she comments , it seems to be a matter of " when " they get home , rather than " if " . Ensign Kim sits glumly alone in the darkened mess hall with a desktop monitor . Janeway enters and sits with him . He sadly tells her what he has discovered : the phase corrections he had sent were wrong ; their use would have severely damaged or even destroyed " Voyager " . It is evident that he is deeply ashamed of himself . But , he continues , he cannot fathom where the other corrections came from , or who sent them . Janeway enigmatically tells him that they came from a " " guardian angel named Harry Kim . " " She explains to him as he regards her , dumbfounded , that Seven found a Starfleet security code in the transmission : his . Further , the transmission had a temporal displacement , showing that it originated between 10 and 20 years in the future . Kim ponders aloud on the paradox of this : how could he have sent the message from the future to change the past if by changing the past , that future was erased ? Janeway gently advises him not to try to figure it out ; all that matters , she insists , is that " " somewhere , somehow , some " time " , you ' ll come through for us . " " She then invites him to listen to it from his own mouth if he does not believe her , and hands him a tricorder . On it , she tells him , is a video message his future self also sent with the transmission , to him here , in the past , now the present . She then leaves him , but not before smiling at him sweetly and proudly . Kim slowly interfaces the monitor and the tricorder and plays the message . The image of the future , older Harry Kim gazes at him with a small smile . It is the same message the future Kim was seen recording . He tells him that if he is seeing this , then the mistake he made fifteen years ago ( sending the erroneous phase corrections ) has been corrected . " " You owe me one , " " he finishes . Kim stares at the image in wonder . Memorable quotes . " " Mr . Neelix , you are an unending source of astonishment . " " " " Why , thank you , Mr . Vulcan ! " " " " Decks Nine through Fourteen are now . . . Deck Ten . They ' ve been compacted . " " " " How many glasses of champagne did you consume ? " " " " One . " " " " Obviously the Borg can ' t hold their liquor . " " " " You see , Doc , fifteen years ago , I miscalculated the slipstream threshold and transmitted the wrong phase corrections to " Voyager " . Boom ! They were knocked out of the slipstream and sent to an icy death ; ' Thank you , Ensign Kim . " " " " But I ' ve had a long time to rethink my mistake , and now I know how to fix it . So . . . we ' re going to send " Voyager " a new set of phase corrections . " " " " Isn ' t it a little " late " for that . . . ? " " " " And how did you get involved with Bonnie and Clyde here ? " " " " I ' ve been interested in " Voyager " for a long time . " " " " They ' re having sex . " " " " Shield Generators ? " " " " Online . " " " " Plasma flow ? " " " " Stable . " " " " Comm . link ? " " " " Secure . " " " " Lunch ? " " " " ( pause ) Salami sandwiches . " " " " I killed them ! " " " " Control yourself ! " " " " They trusted me and I KILLED THEM ! " " " " MR . KIM ! I didn ' t spend all those years in an ice bucket so I could listen to you berate yourself ! If you want to wallow in self - pity , fine ! DO IT ON YOUR OWN TIME ! " " " To aid an honorable thief or to spend eternity in cybernetic oblivion . . ( pause ) Let ' s tempt fate . " " " This is no ordinary phone call , Doc , we ' re talking to yesterday . Timing is everything . " " " " I ' m no time travel expert , but can ' t we just call " Voyager " again ? The past isn ' t going anywhere . " " " " Don ' t you see ? History is repeating itself ! I destroyed " Voyager " once and I ' m doing it again ! " " " " Someone has got to knuckle down and change history , and that someone is " you " . " " " " It can ' t be done , Doc - I told you . . . " " " " No - you told me you can ' t correct their phase variance . Alright - we have to accept that . But what about sending " Voyager " a warning ? Is there a way to get them to abort the slipstream flight ? " " ( Scientifically ) " " Yes . . . " ( Excitedly , realizing all is not lost ) . . . " YES ! I could send a phase correction which would disperse the slipstream entirely ! " " " " If we can ' t get the crew home , at least we can save their lives ! " " " " Warning : Warp core breach in ten , nine , eight , seven , six , five , four , three , two … " " " YES ! ! ! " " " The corrections I sent you were wrong - if you had used them , " Voyager " would ' ve been heavily damaged - maybe even destroyed . What I " can ' t " figure out is who sent the other phase corrections to Seven of Nine . " " " " Looks like we ' ve got a guardian angel . " " " " Oh , I wish I could believe that . . . " " " " Believe it : his name is Harry Kim . . . Seven found a Starfleet security code embedded in the transmission - yours . " " " " If I sent a message from the future , and changed the past , then that future would no longer exist - right ? . . . So , how could I have sent the message in the first place - am I making any sense ? " " " " My advice in making sense of temporal paradoxes is simple : Don ' t even try . . . To " me " , all that matters is that somewhere , somehow , some " time " , you ' ll come through for us . " " " " Hello , Harry . I don ' t have much time , so listen to me . Fifteen years ago , I made a mistake and 150 people died . I ' ve spent every day since then regretting that mistake . But if you ' re watching this right now , that means all of that has changed .
