Back to Ocampa?
Janeway would be guilty that the Ocampa would be running out of food, water and power by that point in the adventure, that she did nothing about it while she was on site, because she was running from the invisible threat of kazon reinforcements.
Kes had weeks to live.
Whatever star drive Kes was using that could cross 30 thousand lightyears in less time than it takes an Ocampa dying of old age to die of old age, would have gotten Voyager home in days but Janeway was too mistied eyed to enquire after the tech or ask for a lift back to earth first.
Unless Kes herself was the Tech/stardrive of course.
