Not what they’re probably going for here, but if Galaxia kills NQS in the 30th Century, she either took a thousand years to pull of killing Usagi (which is unlikely to me, Galaxia is way too capable) OR she just hung around and purposefully played a game of cat-and-mouse for that long, just to see Usagi be afraid and paranoid.

Which, thinking about it, makes for a REALLY INTERESTING version of Crystal Tokyo, because that would put us with an NQS who’s acutely aware of a looming threat, who’s probably consumed by fear and worry. It would make her distant relationship with Chibs make a bit more sense, because if Galaxia’s behind every shadow, she can’t build a good relationship. And then OF COURSE once she realizes she can send Chibs to the past, she would, because it’s safer than the present.

And then maybe one way or another, Chibs going back has a butterfly effect that allows Galaxia to be defeated when she first appears.
