Course: Oblivion: While using an enhanced form of warp drive, the ship and crew begin to mysteriously degrade.
Oh yes, Tom and B'Elanna getting married. *snoooooooooore* Oh, look, Kim playing the oboe. It sorta even makes sense that Chakotay would be giving Torres away. Meanwhile, the rice that gets thrown falls through the floor.
They've also enhanced the warp drive and will only take two years to get home.
"Between you and me, B'Elanna and I don't need aphrodesiacs." Did. not. need. to. know. that. Paris wants to honeymoon on Earth. In the holodeck, of course. Meanwhile, Torres leaves Seven in charge of engineering, but then they find a jeffreys tube losing cohesion.
Crewmembers start falling ill, including Torres - cellular degradation. Neelix finds that stuff brought on board recently seems to be immune. Chakotay and Tuvok attempt to track down when the problem might have started.
Tom tells Torres he decided on 1928 Chicago for the honeymoon, and she promptly dies.
Chakotay and Tuvok discuss the events of Demon and realise that they're all the duplicates from that story. How the hell does the biomimetic compound replicate antimatter? Faced with this news, Janeway says bugger it, we're continuing on to Earth.
Uh oh, Tom's wigging out. Chakotay thinks they should head back to the Demon planet. The crew is dropping like flies. The HoloDoc's only working plan is to find the real Voyager and reimprint the original crew's DNA.
Voyager finds a Y class planet, but it's inhabited and a ship fires on them and forces them to retreat. While debating with Janeway, Chakotay dies. Bummer!
Janeway decides he was right, and they set a course for the Demon world. And continue expiring and melting and stuff. With only Kim, Seven and a few crew members left, they detect the real Voyager and attempt to drop out of warp.
Real Voyager, following the distress signal, finds an expanding cloud of biomimetic compound, and sods off. Teh end.
