问题解答：

Kes' telekinetic powers grow to such a point that she can no longer control them. In order to prevent Voyager from being destroyed, she decides she must leave the ship.
Season 6, Episode 23
Kes returns to Voyager. Aged, angry, and more powerful than ever, she literally tears through the ship. Using her abilities in combination with Voyager's warp core, Kes travels back in time to Voyager's first year in the Delta Quadrant. Her agenda is to kidnap her younger self and return her to Ocampa, even if it means turning her former friends over to the Vidiians.
