Spilling the beans means ruining the surprise...which I'm reluctant to do. Getting blindsided by new complications is part of the original series, and that's what I'm shooting for here. Makes it a bit difficult to just tell you what's up my sleeve, get it?
All I need for this to work is for Ranma, Akane, and Ukyo to be in the same spot for a little peace and quiet, either before or after said contest--getting together to go to the beach, catching a bite to eat afterwards, or whatever. My opinion is that 'beforehand' will work better, but I can work it either way. P-chan, whether he's there or not, plays no part in my scheme. He can be a loose cannon or be completely absent.
I already ran my idea past Kai, and he's cool with it. The question is whether anyone else is comfortable with letting this roll without blocking...because once I get the ball moving, I have no idea where it's going to end up, either.
