As the moon and night sky shined onto Ponyville, Rainbow Dash continued flying towards Ponyville, determined for her revenge. As she was flying, she was thinking of everything she had been through with her older friends. The happier moments.

"You girls are all of my best friends a Pony could ever ask for!"

"I'm glad to have all of you as best friends as well! All of you are awesome in my book!"

"You girls make me happy to be with!"

"I don't know what I would do without you girls!"

"Darlings, you all are some of the most fantastic friends as well!"

"Y'all are some mighty friends to me as well!"

"Let's promise to be here for each other!"

When she was almost about to reach the ground in Ponyville, she also remembered when they brought her back to normal after being corrupted by Discord.

"LET ME GO!! DON'T TOUCH ME!!"

"T-Twilight...?"

"Don't worry Rainbow Dash. Everything will be okay. We are here for you to turn you back to normal. We would never choose to leave you after how loyal of a friend you are, never willing to leave us!"

"Twilight is right. We would never leave ya Dash. Especially me, sugarcube! This was all the works of Discord!"

"W-what happened..? Why are you all around me..?"

"RAINBOW DASH! YOU'RE BACK!"

"Aw.. You girls don't have to hug me, I'm fine! I'm always awesome as usual! Though, I don't know what I would do in a life without all of you.."

"Aww.. Rainbow Dash.."

"Where did it go so.. wrong..." Said Rainbow Dash as her mentality turned back to normal for a brief moment, before returning back to insanity.

"WHAT AM I SAYING? They BETRAYED ME! They are NO FRIENDS for BETRAYING LOYALTY, and they shall soon realize that! ON THEIR DEATHBEDS!!"

She continued flying until she reached the ground in Ponyville. It was still night time, as every pony had their curtains closed and lights turned off. All except the Castle of Friendship.

"Looks like the egghead is still awake. I'll have to come back later when she's asleep, especially since I don't have access to enter the castle during night time anymore. If worst comes to worst, I'll have to barge in through the doors."

Rainbow Dash was thinking of who should be her first victim, until she thought of a particular yellow Pegasus Mare.

"Perfect. She will be my first target. Especially AFTER HOW SHE TREATED ME BEFORE BETRAYING ME..."

"But.. Fluttershy.. How could you betray me...? You are literally the Element of Kindness... Why.. do you and Twilight sudde-"

"Boo, Hoo, Hoo! I don't care Rainbow Dash. Now get the FUCK out of my cottage."

"At least explain to me why you betrayed me..."

"Fine. I simply don't give a shit about you anymore. You're uncool, and a narcissist cunt who thinks too much of herself. Now GET YOUR FUCKING ASS OUT OF MY COTTAGE BEFORE I GET MY HAMMER!"

"I will personally ENJOY watching that ungrateful CUNT DIE!" Said Rainbow Dash with pure malice in her voice as she started to fly outside of Ponyville towards Fluttershy's Cottage.

After a few minutes, she finally arrived at Fluttershy's cottage. The curtains were closed but the lights were on still, signaling that Fluttershy must still be awake.

"This will be harder since she's awake, but it's worth a shot."

Rainbow Dash opened the door to Fluttershy's cottage and walked right inside, alerting Fluttershy who became furious to the light blue Pegasus letting herself in.

"Who SAID YOU CAN COME BACK IN MY HOUSE, BITCH?" Yelled a angry Fluttershy. "GIVE ME ONE REASON WHY I SHOULDN'T BEAT THE SHIT OUT OF Y-"

Before she could finish, Rainbow Dash bucked Fluttershy very strong in her jaw with her front hoof, dislocating it, causing Fluttershy to scream in pain, and traumatizing her.

"M..y j..aw.. R..nb..ow D..sh.. w..y..?" Said Fluttershy the best she could despite her jaw being dislocated.

"R..b.ow.. Da..h.. I..m.. s..or..r..y.. fo-" Said Fluttershy before being bucked in the torso by Rainbow Dash, knocking her down to the wooden floor.

"What's that, CUNT? You're sorry? OH PLEASE. You're just lying." Said Rainbow Dash with a sadistic grin as Fluttershy could do nothing but cry.

"Oh please, SHUT THE FUCK UP BITCH! YOU WANT TO KNOW HOW YOU MADE ME FEEL WHEN YOU LEFT ME THAT FATEFUL DAY? WELL NOW YOU WILL KNOW HOW I FELT!" Said Rainbow Dash as she spotted the same hammer Fluttershy threatened her with to get out of her house. She went over and grabbed it while grinning sadistically, before turning back around towards Fluttershy.

"Now WE'RE TALKING!" Said Rainbow Dash, as she wielded the hammer, Fluttershy's pupils dilating in fear as she starts panicking.

"R..bo..w D..s..h.. pl..as..e.. I..m.. s..o..rr.y.. W..e a..l..l do s..m..et.h..in..g w..e e..n.d u..p r..eg..r..t.t..i..n..g" Said a very panicky Fluttershy.

"It's TOO LATE FOR APOLGIZING! HAHAHA!! YOU WANNA KNOW HOW YOU MADE ME FEEL? LIKE I DON'T MATTER IN THIS FUCKED UP WORLD! I'm.." Exclaimed Rainbow Dash before starting to temporarily regain her sanity for a brief moment.

"I'm sorry.. What AM I DOING?!" Said Rainbow Dash, before bursting out in tears.

"R..ai..n..bo..w D..s.h.. It..s n..o.t yo..u..r f..a..u..t.." Said a weak and emphatic Fluttershy.

"Fluttershy... You need.. to run away... It's coming back..." Said Rainbow Dash weakly. Fluttershy understood this, nodded, and started flying for her dear life outside of her cottage, before Rainbow Dash's insanity came back.

"WHO THE FUCK DO YOU THINK YOU ARE TO RUN AWAY FROM ME BITCH?!" Yelled Rainbow Dash as she flew outside towards Fluttershy.

"I h..v..e t..o t..e..l.l Tw..i..li..ht.." Said Fluttershy as she was trying to fly back to Ponyville in fear, before falling down on the grass in weakness from being bucked in the torso earlier. Soon enough, Rainbow Dash walked over to her in the grass, still wielding her hammer and having her sadistic grin.

"No you're not!!" Said Rainbow Dash as she smashed the hammer down on Fluttershy's back hooves and then wings, preventing her from being able to escape, causing Fluttershy to scream in agony. As the two were outside of Ponyville, Fluttershy's screams sadly cannot be heard by any pony. Rainbow Dash goes back to her house for a few minutes to get a bucket before coming back.

"Remember this BITCH?" Said Rainbow Dash as she dumped the melted wax from some candles she melted in the bucket onto Fluttershy, burning through her skin and causing her to scream the loudest she's ever screamed in agony, all while Rainbow Dash watches in pure malice with the same sadistic grin.

"What's soaking wet and clueless? YOUR FACE!!"

"D..s..h.. Pl...e..as..e.." Fluttershy cooed gently, in fear and agony, her skin scarred in second degree blisters.

"It's been fun and all Fluttershy, but it's time for it to end now. Farewell Fluttershy." Said Rainbow Dash, as she smashed the hammer down onto Fluttershy's head with all of her might, cracking her skull open killing her instantly. As the death of Fluttershy sank into her mind, a flashback came from when they were fillies long ago.

"R-rainbow Dash..?"

"Yeah Fluttershy? What's wro- Y-your torso.. What happened?!"

"The.. Th.... I don't know if I can tell you... They might find me and hurt me again..."

"Who DID THIS TO YOU Fluttershy? They gotta pay for what they've done!"

"I..."

"This is serious Fluttershy! I.. care... about you.."

"Oh.. Okay.... You win Rainbow Dash... It was.. the bully ponies.. in Cloudsdale... Hoops... Dumb-Bell... and Score.."

"WHAT?! Oh, when I GET MY HOOVES ON THEM!! I SWEAR TO CELESTIA!! THEY WILL PAY FOR HURTING YOU! I'll make sure to get them back, without making them hurt you ever again Fluttershy!"

"Thank you so much Rainbow Dash! I don't know what I would do without you! You're so brave..!"

"Anything for you, Fluttershy.."

As Rainbow Dash came back from the flashback, the emotions caused her to come back briefly. As she saw Fluttershy's corpse, she screamed in horror and sadness.

"F-FLUTTERSHY!!" Cried out Rainbow Dash in grief. "Did I... do this..? What am I saying... This was all my fault..." Said Rainbow Dash, filled with grief, as she hugged Fluttershy's lifeless body.

"FLUTTERSHY... I'M SO SORRY!! I'M SUCH A FAILURE.." Screamed Rainbow Dash as she was crying uncontrollably.

She had killed one of her old friends, Fluttershy. Even though they weren't friends anymore and she treated her like shit before, she still ended up killing a friend of hers. There was no going back now from the insanity. It would take her over completely this time. She closed her eyes one last time in her sane mind, before turning back to the insane side.

"What am I saying. She deserved that for backstabbing me. I don't feel bad at all." Said Rainbow Dash as she turned back insane. "I missed this mentality though... Hehe..."

As Rainbow Dash talked to herself, she eyed Ponyville for the location of her next victim.

"I'm coming for you next, Twilight. There is nothing that can save you, egghead!" Said Rainbow Dash as she took off in the sky towards the Castle of Friendship. Meanwhile, a certain Unicorn Mare watched in shock from a distance.
