@Nakromis I believe it's called a stereotype. It goes something like this; the bigger your boobs and the blonder your hair, the less braincells you have, regardless of how true/untrue it actually is.
I think it has more to do with the "look beautiful, don't have to work to be smart in life.
Anyways. This story went completely off the rails when the mirror alternate version of herself came in. Then it turned into Inception levels of complicated plot and introduced way to much stuff that didn't need to be included. It was fine and simple with the "fighting a reality change and losing" concept and it should have been left at that.
