Harmony Divided

Twilight runs through town, dogging shadows in the black of night. It has just turned Midnight and Twilight is chasing after Rainbow, suspecting her of having ties with the murder. She runs into multiple ponies and stands, never cutting off her sight with Rainbow. "Stop right now Rainbow Dash, I'm warning you!" Rainbow stays at a steady pace away from her as they go through the town. Applejack joins Twilight, running along side her.

"Twilight! I know what is happening!" They stop, letting Rainbow get away.

"Then what? What could possibly be happening that you would want to tell me after fighting me to keep silent about it?"

"She made her do it! She wanted her to die so she could take her spot!"

"Wait, slow down, who did what because why?" Applejack facehoofs.

"Ok, listen. Rainbow forced Fluttershy to kill Sky." Twilight chuckles.

"Really, why then? Fluttershy would never, ever kill another just because she was told to. Shs may be feeble, but she is not boneless."

"Isn't she? What do you think she was yelling about? Accidentally leaving an animal for dead  and having a lust for blood? No, she killed sky and enjoyed the power seeing as though she never has any. She wanted more, so she then killed four pets because of a fi-"

"She what?! No, this isn't making any sense. She wouldn't, she didn't, and she loves her animals. Get out of my way, stop lying, and make yourself useful." Twilight goes to run but is caught on the tail by Applejack.

"Rainbow made her kill Sky because it creates sympathy for her. By failing to save Sky she now looks like a tragic hero who failed the most important task for another pony, raising her popularity by just trying to save her. She expects this to be increased by catching the killer who murdered the pony she failed to save, and in turn see the princesses due to the popularity." Twilight sinks it all in.

"But, if what you're saying is true, then why would she want to see the princesses?"

"She want's to overthrow them and divide Equestria." Applejack jumps, being surprised by Rarity.

Twilight grows angry. "What are you doing here?"

"To tell you that Rainbow-"

Applejack interrupts. "We know, but what does she want to divide Equestria for?"

Rarity walks in front of them. "To create the Pegasi the master race. She thinks that they are meant to run Equestria and make all the decisions. We need to stop her." Twilight hates to admit it, but she needs their help.

"I want to know how you two know all of this later, but right now we need an idea." She whips out a pice of paper and starts drawing on it. "Ok, I have a plan. first we-" She is interrupted by the mayor running at her.

"Twilight Sparkle! You and your friends are under arrest for accompanying a convicted murderer by the word of Rainbow Dash!" Twilight turns, pushes Rarity and Applejack and starts forcing them to run.

"Ok girls, keep up with me and stay close." She starts running ahead of them and disappears into the darkness. Rarity and Applejack run from the mayor who now has three guards behind her. A tree snaps and falls over, blocking the guards and mayor from following them. Twilight rejoins the group. "We need to get to RD, do either of you know where she is?"

"Right here." Rainbow flies in front of them, Fluttershy on her back. "I'm sure they already told you what my plans are, but don't worry, this isn't a cliché movie, I won't kill you. But I can't let you get away either, so pick your poison; do you want me to take you in peacefully, or do you want to make this harder than it has to be?"

"You'll never get away with this!" Twilight runs forward, only to run at  Fluttershy who is on the ground. "Wait, where did-" She is knocked to the side, Rainbow slamming into her. She struggles to get up and walks over to Fluttershy.

"Don't worry about her, she isn't hurt... yet." Rainbow runs at Twilight, knocking her over for a second time. "Shame, I thought you'd be more of a challenge. You know, with your super magic and all." She walks twords her but is tripped by Twilight spinning and catching her hooves. She jumps on top of her.

"Why would you do this?! Why do you want a segregated world to live in?! What would there be to gain in it?" Rarity and Applejack help hold her down.

"You would never understand Twilight, what we go through and what you go through are extremely different, and you have it much better off than you realize. I'm just a messenger, giving this message to you and your princess friends. Play time is over." Rainbow knocks Rarity and Applejack off of her and pushes Twilight to the ground. "Welcome to war." She throws her hood forward, knocking Twilight out cold.

The next Friday

...

Rainbow looks in the mirror, making sure her best dress is on right. Today Rainbow goes the castle to meet with Celestia and Luna, her being in Canterlot already makes it all a bit easier. Her fame and popularity lifted her here in a week, this being unheard of happening in such a short amount of time before. Today will go down in history, a day to remember for the great actions taken for the right of the citizens. "I just wish Fluttershy was here to see it." Rainbow says to her reflection. Looking one last time, she turns to only face a picture of all six of them when they were still friends. She becomes infuriated and punches the mirror, leaving the house. This was the last time she left a house as a Pegasus and not a ruler. She left nothing in the house but broken glass and a picture of the six of them, though Fluttershy crossed out in red marker in her wake.
