An interesting point was raised in a Tenchi BBS.  Sasami-chan's 1st dream involved
Kagato's arrival, and sure enough, he showed up.  Her 2nd dream involved her being
alone, being attacked, and Tokimi showing up to take Tenchi.  The point brought up

was whether the events in episode 17 where Sasami is captured by herself may indicate
the dream coming to pass.  What do you guys think?
