She in many ways sort of sabotaged a moment when a previous existing character could of shined more and had their own two parter ending for Season 6. It could have been Applejack, Rainbow Dash, Fluttershy, Rarity, Pinkie Pie, Cadance, Shining Armor, Spike, Celestia etc., a moment for someone that's been in the shadow of Twilight Sparkle so long could have had a grand opportunity to not only be a hero but showcase a different type of hero, Rainbow Dash could be more brash and obnoxious than Twilight making reckless mistakes but eventually finding patience as a virtue, Fluttershy may take baby steps and needs more time to develop into a hero and when she does she finishes it with flying colors.
