I've got a few more ideas... I want to at least get to "tomorrow morning" so that the original Sarah can be seen in her new form, probably a little more than that so she can do something, and then I want to go back and make some branches where the panties end up on other combinations of people.
Karyn has to re=enter the picture somehow, I think, but I'm not really sure how yet. Again, I've got ideas, but I haven't settled on which to go with or how.
