Re: Before & After/Year Of Hell relationship
I recall an explanation of this which centred around Janeway's different hairstyles and ultimately said that the timeline changed. They did avoid any mention of Kes for the most part, though (and when they finally brought her back, everyone wished they hadn't...).
Kim: I'm detecting some weird technobabble.
Janeway: A possibly dangerous anomaly that we know nothing about?
Kim: Yeah. I suppose we should steer clear.
Janeway: Ha! Good one, Ensign. Take us in, Mr. Paris.
