What if the crystal had sent them into an alternate or parallel

I'll bet Pluto is going crazy trying to find them. Maybe that is
why they are there, that world's Pluto stole them.
Ne, or maybe Ail/Ann just sucked Earth dry when the Inners were no
longer there to save everyone. (Or, skipping Rubeus - since he was
attracted back in time partly due to what Sailor Moon would do in the
future - maybe the Silence took that world after all.)
Another possible question is what happened to Usagi's parents
from before?
Retroactive to Usagi's birth. But then, what happened to *Minako's*
parents?
No we have part one of a multiparter here. This raises too many
questions to be answered. How did Minako get a copyright on
Sailor V without revealing her true identity.
By showing up in person, and showing off her powers to prove that she
really was Sailor V, most likely. The rest could be
anonymous/untraceable.
