some people suggest it could be Derpy-related or a new character, outside of the obvious Scootaloo assumptions
if they do do it about Derpy, i'll be both shocked and impressed that they would actually attempt to do that
i'm hoping for a newcomer. have some other episode be about Scootaloo and Rainbow Dash, unless the disability episode allows her to fly by the end of it. too close of a shave if you ask me
