Derpy and the princess took off into the sky with Red Rover and his helpers right behind. Unluckily they were under the clouds so the ponies below could easily see them. Suddenly a red blur crashed into Derpy sending her falling downwards. She flapped her wings trying to regain her flight but instead she hit the ground and dust flew upwards.
She heard hooves hitting the ground. She opened her eyes to see a brown earth pony looking down at her.
"Are you ok?" He asked. He had an accent not much different to the farm pony Applejack's. Derpy stood up and brushed the dirt off.
'What's you're name?" She asked.
"Call me The Doctor." He replied smiling. He held out a hoof and Derpy shook it.
"Nice to meet you Doctor." She said.
"Did you happen to see a pony named Red Rover on the way here?" He asked. Derpy nodded.
"Yeah. How come?" She asked trying not to sound nosy.
"Well he's an alien who is trying to take over the world." Derpy looked confused.
"He's an alien inside a pony, on a different planet, in a different universe." He explained. Derpy nodded to show she understood.
"Could I help you stop him?" She asked. The Doctor nodded.
"I actually know how he became a pony because it happened to me. I came to this world and... now I'm a pony." He told her. There was a noise from overhead as Princess Celestia, followed by Red Rover and his helpers, rushed past.
"Come on!" Shouted The Doctor. He ran underneath them as Derpy flew up behind them. They were about to enter a chase.
Derpy sat in her bedroom crying. It had been six months since she had found out about her daughter's dissapearence. She hadn't left for any of it. Many of Ponyville's inhabitants had tried to get her to let them in but she refused. Nopony knew about the dissapearence. She had given up all hope of ever finding her daughter. So there she was the tears streaming down her face when there was a sudden crackle downstairs. Derpy perked up instantly. She slowly walked out of her bedroom. Her sadness had been overcome by fear. She carefully went down the stairs. She slowly opened her living room door and went inside.
When Derpy saw who was standing there she almost fainted. She was nervous. She hadn't seen Princess Celestia since before she had gone on the mission. That meant she was probably here to have a talk about the incident with Discord.
"P-P-P-Princess Celestia?" Stammered Derpy.
"Hello again, Derpy." Replied Princess Celestia "I heard you forgave Discord for everything he did." Derpy suddenly froze. Her heart sank. Celestia had found out.
"Uh... I-I-I-" She began only to find herself stopped by Princess Celestia.
"It's okay." Princess Celestia told her "I should of seen it sooner." Derpy's eyes widened in suprise.
"B-b-but I thought you'd be mad at me." Derpy said.
"That's not why I'm here, though." Celestia told her. Derpy's eyes widened even more.
"What?!" Derpy exclaimed.
"I'm here to give you another mission." She said putting a hoof over Derpy's mouth before she could protest "The mission. Is to save your daughter. I believe she is the missing link in a chain of events I am investigating." She removed her hoof from Derpy's mouth to allow her to speak. She didn't say a word. As soon as her mouth was free it dropped open.
"B-b-but how could my daughter have anything to do with it?" Derpy asked.
"Because the chain of events happened in the summer camp she was at." Princess Celestia replied. At that moment there was a flash of bright white light. As soon as it had faded Derpy realised she and the Princess had been tied up.
"Don't worry, Princess. I'm taking control of this party now." Taunted a voice.
Derpy glared at the pony that looked down at her. For some odd reason she felt hatred seeping out of him. It was like she knew him. All she knew was that they definetly weren't friends.
"You never did have a very good memory." The pony taunted. Derpy ignored him. She had always been made fun of in school so she didn't care. Then she realised who this was.
----------------------------------------------------------Flashback----------------------------------------------------------------------------
"Hey look!" Jeered a pony "It's that stupid mare! Hey, Derpy!" Derpy ignored them. Her real name was Ditzy. But she had always had that name. Even her parents called her Derpy. It was just because of her eyes. She was different so they made fun of her. Everypony was mean to her. But there was one pony that she hated the most. He always hurt her. Sometimes Derpy was knocked out. Whenever it happened she had always woke up outside. She was treated like trash.
----------------------------------------------------------Flashback------------------------------------------------------------------------------
Derpy suddenly felt pure hatred towards this pony. He could obviously tell.
"So you remember me now do you, Derpy?" The pony laughed. Derpy suddenly felt confident. More confident than she had ever been in her life.
"My name is Ditzy Doo." She shot back "And I am NOT as stupid as you think." The pony just laughed.
"Well it isn't very obvious!" Exclaimed the pony mockingly.
"Actually. I think I'm alot smarter than you. Because I think you forgot that Princess Celestia has magic." Derpy said. The ponies eyes widened as the princesses horn glowed. There was a snapping sound and the two mares were free.
"Do you have an escape plan?" Whispered Princess Celestia.
"Yes." Replied Derpy "Distract them and run and like hell."
"What sort of plan is that?" Asked the princess.
"I don't know." Derpy replied. Suddenly the pony lunged at Derpy and knocked her to the ground. He started repeatedly punching her in the face.
"YOU! BUCKING! IDIOT!" He yelled punching with every word. It seemed like he had punched her for minutes before the princess finally recovered from the shock and used her magic to pry him away from the almost unconcious mare. Celestia glared at the struggling pony. Derpy slowly got up.
"You think you're so clever don't you, Red Rover." Derpy said confidently "But a clever pony would have a plan before they captured someone."
"Oh look who's talking!" Red Rover exclaimed "'Distract them and run like hell'? What sort of plan is that." Derpy looked at Princess Celestia.
"New plan." She whispered "RUN!" Derpy and the princess suddenly stormed past Red Rover and his helpers.
"After them!" He ordered. All of his helpers ran after them.
