Given that Sailor Pluto stands at the Door of Time, wouldn't she immediately recognize Usagi and co, when they were attempting to travel back through time?
I never quite got how she seemed to be ignorant of who they were and nonetheless attacked them. After all, she knew of NQS, Mamoru, and the Inner senshi of Crystal Tokyo, so why respond that way?
Also, what was the deal with the Black Moon clan being able to travel through time without Pluto's agency? How'd that happen?
