Course : Oblivion ( episode ) As " Voyager " crewmembers begin dying , they make a startling discovery about their true identities . Summary . Teaser . In ' s mess hall , a formal and happy occasion is occurring : Lieutenant s B ' Elanna Torres and Tom Paris are holding their wedding . Captain Janeway is the master of ceremonies , Commander Chakotay is giving Torres away while The Doctor takes pictures of the occasion . Harry Kim plays the clarinet along with a bassist and a guitarist . Torres and Paris exchange their own vows , taking ring s from Kim and Chakotay , and then Janeway proudly declares them husband and wife . Seven of Nine has the honor ( unbeknownst to her ) of catching the bouquet that Torres tosses over her shoulder . The rest of the crew happily toss rice over the couple to shower them with blessings as they depart from the mess hall . Below the place of celebration , however , the metallic structure of the deck s begin to distort ominously and the thrown grains of rice begin seeping through to the Jefferies tube underneath . Act One . Life is good for the crew aboard " Voyager " , as well as the wedding a newly enhanced warp drive has been built that will get the crew back home in two years . In her ready room , Janeway and Chakotay are busy deciding on whether to stop along the way to study an anomalous gradient in the curvature of space that their ship will pass by in six months . Meanwhile , Neelix is busy helping the newlywed Tom Paris decide on where he and his new wife would want to spend their honeymoon . While Neelix offers holoprogram s of exotic places in the universe , such as a mountain resort on the fifth moon of Cytrax with its reputed " auditory aphrodisiac " cricket songs and the beaches of Ahmedeen with its seas of liquid argon , Paris is hoping for his honeymoon to be a little more " down to earth " , as in being on Earth during the 1920s in Chicago . Neelix thinks he isn ' t thinking exotic enough , but Paris doesn ' t think so . In main engineering , Torres prepares Seven to take care of things while she is on her honeymoon when a strange reading is picked up in a Jefferies tube underneath . They investigate what ' s supposedly a minor fluctuation , on the way discussing Seven ' s willingness to pursue a relationship . However , a serious situation develops as a tricorder scan of that section reveals that it is losing molecular cohesion . The crew suspect that their new enhanced warp drive is causing subspace radiation that is somehow breaking down the molecular bonds in all surrounding sections . What ' s confusing is that , as Kim notes , they ran many simulations and were confident there was no problem . Even taking the warp core offline doesn ' t stop the problem . Janeway orders Torres to try isolating the cause of this problem and to stabilize the affected areas . After examining the warp field ' s schematic s and finding no solution to the problem , Torres goes back to her quarters . Oddly , she finds herself shivering , even though the room temperature hasn ' t changed . She goes checking herself in the bathroom mirror when she notices an erupting blotch on her face . By the time Paris arrives at their quarters for dinner , he finds that Torres has become violently ill and takes her to sickbay , where Ensign Ashmore and Lieutenant Nicoletti are already being treated for the same conditions . They have an epidemic . Act Two . The Doctor discovers that she is dying of acute cellular degradation , another effect of the radiation . The engineering crew is showing the first signs of this degradation , but The Doctor soon discovers that the rest of the crew is also affected , including the captain . Comforting his wife , Paris tells her about his plans for their honeymoon at the Graystone Hotel , but she dies moments later , despite all attempts of reviving her . Meanwhile , after discovering that items brought on board in the past few months are not degrading with the rest of " Voyager " and her crew , Chakotay and Lt . Cmdr . Tuvok backtrack " Voyager " s course over the past year to see if there is anything that could be causing the degradation . They come upon the encounter of the biomimetic lifeform s created by the " Silver Blood " on the Demon Class planet in the Vaskan sector , which they naturally assumed they had left behind on the planet after their encounter with them . They come to a disturbing hypothesis and go back to sickbay , asking The Doctor to perform a test where Torres ' body is injected with a dichromate catalyst . The results show that she was a biomimetic copy . In fact , every member of the crew and " Voyager " itself are biomimetic copies . Act Three . All the crew have memories which have been copied from the originals – part of why the crew doesn ' t remember being copies – but for some reason they soon forgot they were duplicates . They realize they didn ' t think the warp drive radiation was harmful to them because it isn ' t to humanoids . Even The Doctor isn ' t immune , as he points out , as all of the holoemitters including the mobile one are copies , and so will also eventually degrade . Janeway decides that , despite their perilous state , their goal is still to return to Earth instead of going back to the Demon planet , which Tuvok believes would stop the degradation . She orders that they find the nearest Y - class planet and simulate the same atmosphere on the ship as soon as they can . Janeway informs the crew in the mess hall . They can ' t believe it , and start to wonder about themselves and the " real " " Voyager " . Janeway orders crew shifts to be cut in half so they don ' t exert themselves . Some , especially Paris , disagree with keeping to the original " Voyager " s mission , but the crew follows their captain ' s orders . Chakotay disagrees as well , and , during their weekly dinner in private , voices his strong belief that they should go back to their planet , but Janeway disagrees , saying she ' s been on their mission for five years . Later , The Doctor suggests to the mimetic Janeway to find the real " Voyager " so that the duplicate crew could copy the original crew ' s genetic patterns to prevent further degradation , but Janeway dismisses the idea as impractical as they are completely unaware of " Voyager " s position in relation to their own . Just then , a class - Y planet is located . Upon arriving , " Voyager " commences landing procedures , but , unfortunately , a mining starship arrives and states that the planet resides under the Ord ' mirit Mining Treaty and threatens to destroy " Voyager " unless they leave . Act Four . Janeway tries to explain their situation , but they won ' t listen . After " Voyager " s weapons prove ineffective , Tuvok suggests a way to destroy the mining vessel , but Janeway orders the landing canceled , reminding the crew they are still Starfleet officer s . She has them send a distress signal on all bands in the hopes that the real " Voyager " will find them while also maintaining their course to the Alpha Quadrant . Chakotay feels that their journey has gone far enough and bravely confronts Janeway in her ready room to express his and the remaining crew ' s desire of returning to their real home of the Demon planet . In the midst of the heated conversation , Chakotay ' s degeneration becomes critical and he is admitted to sickbay , only to die moments later . Realizing her error in judgment , Janeway decides then to follow her first officer ' s advice and turns the ship around , bringing back online the hazardous new warp drive and setting a course for the Demon planet . Act Five . Over time , " Voyager " continues to fall apart and the crew continue dying as the ship suffers further degradation . The Doctor is now permanently offline due to the holoemitters no longer working , and with Paris ' condition not improving , Neelix is now chosen to be the new chief medical officer . Seven of Nine ' s modified nanoprobe s are keeping the warp field stable , hopefully long enough for the ship to reach the Demon planet . Janeway orders the creation of a time capsule out of non - biomimetic materials to preserve the memory and record of the duplicate " Voyager " crew and what they have discovered and experienced on their journey . Suddenly the main deflector fails , and interstellar dust begins to contaminate the warp field . Harry Kim reinitializes the deflector in time to preserve the warp field , but as Neelix begins calls for celebration , the bridge crew discover that Janeway has died . Continuing on , Kim takes command of " Voyager " , assisted by Seven , with Neelix tending to the dying crew remaining . The degradation has become so severe that life support begins to fail with less than ten hours left of air . Kim orders the time capsule launched , but because nearly all systems have failed , the launch fails , destroying the capsule and taking with it all record of the crew ' s adventures and existence . Suddenly , a vessel is detected , 22 light - years away ; the real " Voyager " . Kim attempts to hail them , but communications are out . They must drop to impulse to contact them , but the warp drive does not respond to controls . Kim orders the core ejected , causing the ship to spin out of control and tear itself apart . Meanwhile , the original " Voyager " has detected the distress signal and is proceeding to its location . Upon arrival , the crew finds only formless debris . With no traces upon which to make further investigations , Janeway makes a note of the encounter in the ship ' s log , and the crew continue on their way home . Memorable quotes . " " The idea is to shower the couple with a symbol of good fortune , not garnish them like a roast chicken . " " " " Given the volatile nature of their relationship , one might have predicted homicide rather than matrimony . " " " " When it comes to affairs of the Human heart , it is wise to look beyond logic . " " " " B ' Elanna has asked me to forgo the rigors of Klingon painstiks in favor of a more traditional ceremony . " " " " They ' re saving the painstiks for the honeymoon . ' " " " " Congratulations . " " " " For what ? " " " " You may not want to know . " " " " You stood by me when most people would have run for the nearest airlock . You were willing to see past my shortcomings , and take all the bumps and bruises that come along with it . You made me a better person , even though I put up one hell of a fight . I look forward to our journey together . " " " " Just you , B ' Elanna , and the crickets . " " " " Crickets ? " " " " Cytraxian crickets . " " ( His voice gets very sly ) " " Their song is reputed to be an auditory aphrodisiac . " " " " Ah . . . well , between you and me , B ' Elanna and I don ' t need aphrodisiacs . " " " " So , who ' s the lucky guy ? You caught the bouquet that means you ' re next in line for the altar . " " " " Yes The Doctor informed me of that archaic Human superstition . " " " " How about Harry Kim ? " " " " I fail to see the benefit of monogamous relationships . " " " " So you want to stay single ? " " " " If you mean remain open to social situations with a wide variety of individuals , then yes . " " " " I ' m married . I ' m not going into stasis for the rest of my life . " " " " I do not wish to be dependent on anyone . By marrying one limits , one ' s romantic interactions to a single individual , a circumstance which implies extreme monotony . " " " " I ' m glad we had this little talk . " " " " How ' s my old lady ? " " " " Well enough . . . to break your nose if you call me that again . " " " " The holographic projectors in sickbay went offline at 0300 . We ' ve lost The Doctor . " " " " We ' ve lost Commander Chakotay . Duplicate or not , he was real to me and he was a fine Starfleet officer , and he was a friend who wasn ' t afraid to let me know when I am wrong . " " " " We received a distress call at 0900 hours . . . arrived at the vessel ' s last known coordinates at 2120 . The ship was destroyed . Cause unknown . No survivors . " " Links and references .
