There is a sequel now: https://www.fimfiction.net/story/372198/the-broken-harmony
Diamond Tiara tells Snips and Snails to make Scootaloo fly off of her scooter. Once she does, she has to go to the hospital. Diamond Tiara's complete indifference to her agony cracks Scootaloo's mind. She is so enraged, so burnt up inside, she goes on a murderous rampage.
The other two Cutie Mark Crusaders, Apple Bloom and Sweetie Belle, are horrified to see what has become of their once close friend. This breaks what was left of Scootaloo's heart.
The always loyal Twist wasn't horrified, but interested. She became an accomplice and a good one at that.
Will the police be able to stop this freakish filly?
All the dislikes tell me is either "I don't normally read stories with story! AND I ONLY READ ONE CHAPTER!" or "I'm 9 and I'm upset about poor Scootaloo". If there's another reason, I'd love to know.
