Cool episode but how did this not effect the human world? Without the sonic rainboom Twilight never would've become a princess. If Twilight was never a princess there would be no crown for Sunset to steal, no way for Sunset to become a raging she-demon, and no way for her to be reformed into the nice Sunset that we had in The Friendship Games. Considering that movie runs parallel to this special there should've been changes going on throughout the whole film.
