...In particular, I hadn't thought of Endgame that way. Instead of being annoyed, all of a sudden I'm thinking "I wonder WHY Janeway changed so much? That sounds like a hell of a story! Maybe we'll get it someday!"
THAT is a story I would like to see explored as well. What happened in the original timeline where voyager took 16 more years? How did everyone differ? How many times did they save all of creation?
I know that the Full Circle mission is only supposed to last until 2384, but maybe it will just be continuous instead. We may see some of those events still pan out.
