~This is what I've gotten from research. None of it is neccesarily true!~
Either Josie or Jane*, J will be short-haired blonde and what appears to be green eyes which would make sense since there's one blonde with green eyes and that one has bangs. This actress has bangs, but we all know that could be easily changed for the movie. In the following picture the wheelchair-bound J has no bangs. So should we go off the book illustrations or an actress' haircut? I say the book! Here is what I'm assuming from my reasearch:Josie*
-Light skin (both)
-Green eyes (actress)
-Blonde, short-haired (both), no bangs (book)
-Wheelchair-bound (book)
*I think Jane was the psuedonym for Josie just like Velma was for McKenna. I like Jane more though...
