That idea is good. Fitting to the episode and thought out of the box. Fandom, I love your creativity.
Man, that would be a twist if she would have managed it somehow to leave the comic book, kidnapped Fluttershy and disguised as her to sneak into the group and prepare revenge on Twilight and her friends.

I bow in front of this creativeness and unique idea.
