Villains aren't born; they are created.
Rainbow Dash lay in her bed still. She looked at the clock. “00:30…” Rainbow Dash mumbled. She closed her eyes shut and tried to fall asleep.
Scootaloo came into the room “R-Rainbow Dash?” Rainbow Dash turned to the other side to look at Scootaloo.
“Why aren't you sleeping?” Rainbow Dash asked calmly. Scootaloo came closer to Dash’s bed. And looked around.
“Um… Rainbow Dash? I-I can’t sleep… I am having nightmares… can I sleep with you?” Scootaloo quietly said. Rainbow Dash raised an eyebrow.
“I thought you were over with these nightmares, squirt.” She said, looking sharply at Scootaloo. Scootaloo blushed.
“Well… I just… can’t sleep.” She whispered looking at Dash with a pleading look. Rainbow Dash shrugged smiled and patted on the bed. Scootaloo smiled and gently tucked herself in bed with Rainbow Dash.
“Dash?” Scootaloo asked uncomfortably.
“Mhm?”
“How did you… how did you become interested in the Rainbow Factory?” Rainbow Dash looked at Scootaloo and thought for a moment. She sat up and showed Scootaloo her flank.
“See this cutie mark?” Dash asked. Scootaloo nodded. “Remember when I told you the story about my Cutie Mark?”
“Of course! It was the coolest story that I’ve ever heard!” Scootaloo said excitedly. Rainbow Dash chuckled.
“Well, it wasn't really the true story…” Rainbow Dash said frowning in guilt. “You see, my parents worked in the Rainbow Factory and when I was a really small filly… I had a different mane color… It was…red. My mom and dad took me to the Rainbow Factory so I could see the process of the work. They thought that it would ‘improve me’ and they thought that if I saw the process, I would get scared and become a very ‘good’ filly and even pass the test. They were wrong. The way they tortured the Pegasi made my psychology go all wrong. I enjoyed the way the Pegasi moaned and screamed and shouted for mercy, how they cried for help. I saw how the Ponies that were killing… were enjoying themselves and how they crazily laughed…I also wanted to. Then, I got my cutie mark. It symbolized that I was born to be a Rainbow Factory worker. The other workers were quite happy about it and let me stay for a while when my parents went for work. I was enjoying myself but something happened. As I wondered off to explore the factory, my parents didn’t know it. I saw the place where the rainbow was formed and I accidently fell into it. My red Mane changed into Rainbow color and the radio-active rainbow gave me the ability to do sonic rainbooms, my Cutie Mark faded and came back to me when I preformed my first sonic rainboom in public. I lied to everypony about how I got my Cutie Mark, I really wanted the job and if anypony found out, I would lose it. When I finished flight school, I was sent to the Rainbow Factory straight away. I was very good at it, it was my special talent. I never gave mercy to my victims and I worked hard and got promoted a few times. I got a lot of money and that’s how I afforded this house! I’m a very trusted pony there and everypony likes me.” Rainbow Dash finished her story and saw Scootaloo sleeping. Rainbow Dash smiled and kissed her muzzle. “Good night squirt” Rainbow Dash fell on her pillow and Scootaloo smiled.
“By Rainbow’s stories… I feel more convinced to do this… maybe it won’t be that bad after all.” Scootaloo said to herself, and fell asleep.
