But in this case, I'm just curious but who would decide to stay behind with Janeway?
I'm not a Voyager expert like you guys, so my ideas may seem ridiculous to people who know the characters far better than I.This wouldn't be a single episode, or even a three parter necessarily. Maybe an entire season's worth of gradual changes leading to big decisions by the characters.
Stays in the Delta Quadrant:
Seven: Sacrifices herself to cure the Borg.
Janeway: Decides to stay behind to aid the now helpless former Borg. Not doing so would make Seven's sacrifice pointless.
Chakotay: The Maquis are long gone. He stays by his captain's side. It's where he belongs.
B'Elanna & Tom: I don't think the Alpha Quadrant treated them very well. I think they would both be willing to try a fresh start in the Delta Quadrant. The tougher question is, would they want to keep the baby on board and in possible danger, or would they settle down on some peaceful planet? I think their arc leads them to seeking a quieter family life, but still willing to go on the occasional adventure with their captain.
EMH: Shaken by the death of Seven, he puts away his childish daydreams of fame and glory back on Earth and devotes his life to helping the ex-Borg and all of the other inhabitants of the Delta Quadrant. Ironically, he becomes a legend to countless future generations of Delta Quadrant citizens.
Kes: A very old - but completely sane - Kes makes a final appearance and uses her now immense powers to return all of the members of Voyager who choose to leave to the Alpha Quadrant. Weakened, she returns to her home world to live out her final days with...
Neelix: He has no real reason to want to go to the Alpha Quadrant. He chooses to stay behind to watch over Kes and eventually makes the Ocampa his new family.
Goes home:
A large percentage of the unnamed crew: I think that many of the people who have been lost for all these years would be willing to jump at the chance to return home.
To replace them, you would see a lot of new faces in the background during the last episode of the show. Reclaimed Borg, and various members of races we have met throughout the seven seasons.
Tuvok: Returns home. He has a wife and family that he loves very much. I would love to see a shot of Vulcan, with Tuvok being welcomed by his family.
Harry: Last scene of the show is Harry sitting in Quark's bar, an extra pip on his collar, Libby by his side, recounting the adventures of the Voyager to a spellbound audience. In the end he toasts his absent friends and we see a majestic shot of the Voyager sailing through the Delta Quadrant.
That's right -
Harry got promoted, got the girl, and got the last word!
However, if you look closely, you can see that Libby is wearing a pair of Quark's Lobi crystals. Damn it Starfleet, will you never learn?
