Chapter 4:

The Insanity of Princess Twilight Sparkle

Twilight awoke in her bedroom. She felt dizzy and was very tired. She noticed her 5 friends and Crystal next to her. "What... happened?" She asked.

"You... you..." Crystal said with worry in her voice.

"Tell me." Twilight had a bad feeling she did something horrible.

"You... ripped... Rarity's tail off... and popped all Pinkie's balloons... and..." She sighed. "Burned 20 of Applejack's apple trees and broke Fluttershy's bunny Angel's leg and hurt Rainbow Dash's wings... all with your horn glowing and white eyes..."

Twilight had a look of horror on her face. "I... I don't know why I did it... I'm so sorry... I just read the back cover of the changelings book and turned to Chapter 3 instead of Chapter 4 like Celestia said to... Starswirl the Bearded's letter on the back cover said to..."

"It's... fine Twiligh'." Applejack said with a small smile on her face.

"I ordered more balloons Twilight! I'm fine!" Pinkie started bouncing around the room.

"It... will grow back..." Rarity looked at her stub of a tail.

"My wings are better already, don't worry about it." Rainbow Dash flexed her wings.

"Angel... is getting better..." Fluttershy looked at Twilight closely. "Why?" Fluttershy had tears in her eyes. "I... don't know. I felt dizzy and fell asleep for a bit... I didn't know I was doing such horrible things."

Twilight got up and looked in her mirror. Her hair was completely straight, like Pinkie's when she's very, very sad. Her horn was fine. Suddenly her eyes twitched and everything was tinted white a bit. Her horn lit. "What's happening?" Crystal used some of her changeling magic to put a forcefield around Twilight. A few minutes later, Twilight returned to normal. "Twilight. Something is wrong with you. You need to be careful. Read Chapter 4 of that book and throw it out. It's too dangerous." Crystal gave Twilight the changelings book. She read Chapter 4 and went outside.

As she walked through town, everypony was staring at her. Her eyes were red and her mane straight. Nopony moved when she walked past them. Twilight boarded the train to Canterlot and sat down on a seat. She put a forcefield around herself and closed her eyes. When the train arrived at Canterlot, she opened her eyes and her forcefield was still there. She got off the train and flew to Celestia's bedroom window. She knocked and Celestia opened the window.

"Twilight Sparkle. Why are you here? Come in."

Twilight told Celestia the story about the book. "I got dizzy and turned to the beginning of Chapter 3 to see where Chapter 4 was and I fell asleep and tortured all my friends." Twilight had tears in her eyes.

"My old student." Celestia looked calm.

"I have an idea. But it will take one week. You will have to stay here. Write a letter to your friends and meet my in the magic room next door." Celestia left. Twilight wrote her letter.

Dear my 6 pony friends and Spike,

Princess Celestia has something that will heal me. In one week, I will be cured of this thing that I have.

Twilight walked to the magic room while still writing.

If I don't come back in one week, come to Canterlot and find me. I may be lost,in my mind or in sleep.

I hope you are well,

Your friend,

Twili_

"Hello Twilight Sparkle."

Queen Chrysalis was behind her. She grabbed Twilight with her magic and sent the letter.
