Here are some spoilers for remaining season 6 episodes. Do not read further if you wish to be surprised!
"Muse" - nothing else known now;
"Fury" - evil Kes episode
"Life Line" - sees return of Barclay, Troi. Doc gets sent to Earth using technology from "Pathfinder" (I'm thinking microwormhole) and tries to save a dying Lewis Zimmerman
"Roll Call" - three aliens pose as Janeway, Chakotay, and Tuvok
"The Haunting of Deck Twelve" - Tuvok time travel episode, a lead in to finale
Finale: "Unimatrix Zero"
- two parter, probably cliffhanger
- Borg encounters resistance from within
- Seven gets involved, possible romance forms
- Queen may appear again
- Delta Flyer destroyed
- Half of senior staff assimilated
- Tom promoted to Lieutenant
NOTES: Yes, I know, the spoilers from "Unimatrix 0" seem... interesting, to say the least. However, they were supplied from some, who, as I understand it, has been very reliable when giving episode information. Also, although it may be a little odd, the assimilation of half the senior staff may explain why Tom get promoted, specifically if some of those assimilated are Chakotay or Tuvok.
Also, according to the schedule, finale night for Voyager starts at 8 PM, which leave me wondering if "Unimatrix 0" will air all at once, or if "Haunting...Deck 12" will be aired just before, as "Deck 12" is supposedly a lead in to "Uni..0" - it could also simply be airing one hour earlier.
So, what does eveyone think?
