Twilight Sparkle never meant to do anything wrong. But then again, all magical mistakes are caused by ponies who have no idea what happened. That's why they're called mistakes. The only difference with Twilight's mistake is that it accidentally sort of turned her into Princess Celestia. And now she doesn't know how to change back.

When Scootaloo finally realizes that there's somepony who seems to have forgotten she exists, she decides to work her hardest at gaining the attention of her idol, Rainbow Dash. With the help of her friends she'll learn to discover that there is something inside of her that can't be reached just through following in somepony's footsteps, and that sometimes a little forgetting can lead to something worth remembering.
