Indeed. But I'd guess they go with the one time stream theory in Sailor Moon. 
Otherwise Pluto really wouldn't need to give a damn about protecting the time 
stream, since there would be infinite possibilities, so the right one would
happen. 
Which reminds me: if there were an infinite number of time streams
in SM, would that mean that there is an infinite number of Sailor Plutos?
In that case the time gate would to be crowded at times. So that's one more
reason to belive that there's only one time stream. ^_^

For *some* bizarre reason, I'm reminded of the Star Trek: Next Generation
episode "Yesterday's Enterprise." Guinan *knew* that the timeline had been
changed, that something was wrong. Hmmmm . . . could Sailor Pluto have
been part El-Aurian? (Guinan's race)
