Are you going to let her know what happened to Ranma? You'd better.

The slow finding out is half the fun of the story.  The way the story is 
unfolding I would expect Michiko to have found out by the end, she's 
hanging around so much that I don't see it can be avoided.  Her reaction 
will be interesting ("Yay! Big Bro/Sis in one" or "You sneak Ranma" or 
some less obvious variation...) and whether or not Nodoka finds out as 
well intrigues me.

Actually, you came fairly close to the exact quote, but didn't quite hit 
it. ;)
