In the Rainbow Factory...

"Dr. Atmosphere, in my office now." Rainbow Dash said over the income. About a minute later, he arrived.

"Yes?" Dr. Atmosphere asked, opening the door to Dash's office.

"I... kinda need help. I usually would have my- *ahem* 'friends' help me, but they can't do anything now. So you're one of the best ponies I can call right now."
"Is it about them again?"
"Yes! I don't know what to do! And you know I can't stay here, even with Rainbowrio working here too."
"Well, you could've called her here instead."
"Yes, yes. Well, she's busy. I don't know where. I think she said she had to finish a book- or was it a story? Nevermind- that she had to finish."
"She's so busy with those these days."
"Yes. But we're not here to talk about her."
"Yes, yes. We're here to talk about your 'friends'."
"'Friends'..."

"Princess Celestia said we might be able to get her back... but how?"
Twilight paced around while her friends sat in their assigned seats.

"She said maybe so it's possible we won't." Applejack said.

"I know. We have to try. But I don't know how."
"I know! Let's have a BIIIIIIIIIIIIIIIIIIIIIIIIIG party and ALL OF PONYVILLE WILL BE INVITED!!!"
"That's not going to work, Pinkie. We have to try something else."
"Make her a cake?"
"No."
Pinkie Pie gasped.
"LET'S MAKE HER CUPCAKES!!!"
Everypony turned towards Pinkie Pie. She facehoofed herself.

"It's just a made up fanfic. Like I would actually kill somepony for a cupcake, let alone any of you guys or Dashie!"
"Yeah. We've been in your basement anyway."
Twilight Sparkle sighed and finally sat down on her throne.

"I regret this..."

"No... stop..."
Rainbow Dash muttered in her sleep.
"Stop... StOp..."
She began to twitch violently.
"No... no... NO!"
She shot out of bed.
"Oh Celestia no... I can't kill them."
She took a deep breath and flopped down onto her bed. Somepony knocked on her door.

"Whaaaaat? Give me a sec." Rainbow Dash got out of bed, fixed her mane, and put on her uniform. She walked over to the door and opened it.

"Dr. Atmosphere? The hay are you doing here?" Dr. Atmosphere sighed.

"I'm sorry to disturb you, but your... 'friends' are here again." Rainbow Dash rolled her eyes.

"Tell them if they ever come here again, then my guards will TAZE THEM and I will bring down the ENTIRE Lower part if the Factory on them if VERY. NECESSARY." Dr. Atmosphere nodded and flew away.

How much longer will it take before you actually agree to kill them?
Just stop...
You'll agree soon...
Shut up...

"Rainbow Dash!" Twilight burst into the room.

"What the- TWILIGHT!? WHAT THE FUCK ARE YOU DOING!?!? YOU'RE NOT SUPPOSED TO HAVE YOUR ASS IN HERE!!!"
Twilight flinched.

"D-did you j-just... s-swear?" she asked, bringing a hoof to her mouth. Rainbow Dash facehoofed herself and swore some more under her breath.

"Yes. Now tell me how the hell you got in and how you aren't dead yet."
"D-dead?"
A wicked grin slowly spread across Rainbow's face.

"In the Rainbow Factory... Where your fears and horrors come true..."
"W-what?"
"In the Rainbow Factory... Where not a single soul gets through."
Dr. Atmosphere came in and grabbed Twilight. He blocked her magic and Glaze tied her wings and hooves together.

"I'm sorry, Princess. But I can't let you go now..."
"Rainbow! What are you doing!?"
"Oh, I have to lock you up for now."
"B-but why?"
"Where your fears and horrors come true..."
The way Rainbow Dash said that sent chills down Twilight's spine.

"Lock her up. If any of my other 'friends' come in, make sure they don't escape. I already have plans for them."
"NO!"
"Shhhh... I'll take your horn and wings away if necessary."
Twilight got a bolt of magic ready. Rainbow Dash chuckled and got up in the alicorn's face.

"Look at you. So desperate to get out. I was planning to let you and the others live, but you wouldn't stop bugging me. And you finally reached my maximum annoyance with you all. Desperately trying to get me back. But that's never going to happen. After your... betrayal."

Rainbow Dash grabbed Twilight's horn and jerked it off. Twilight gasped.

"A-AH!"
"Take her away."
Twilight struggled against Atmosphere and Glaze's grips but without her magic, it was difficult. The last thing she heard from Rainbow was that one line that made it feel like hundreds of bugs were crawling across her skin.

"In the Rainbow Factory... Where not a single soul gets through..."
