Blood is Thicker Than Water

Samantha's POV.
It's been a quiet day in SugarCube Corner. It's been another week since Derpy joined us. Today, it was her turn to make some muffins. But she said she wanted to do this one on her own. So she was in the cellar, with our newest victim, Roseluck, while Pinkie Pie, Apple Bloom, Ellie and I were in the kitchen making icing and decorations for our newest batch of pastries.

While fiddling with some fondant icing, Ellie froze and stared at the table.

"Ellie? Are you okay?" Apple Bloom asked my Bat Pony sister. Ellie didn't reply.

I looked my sister over and noticed the Cutie Mark Patch of three wisps on her hoodie changing color. The purple wisps were changing green, then light red. Ellie senses something's gone wrong.

Ellie blinked and gasped, as she dropped the icing onto the table.

"What is it? What's wrong?" Pinkie asked in concern.

Before Ellie could answer, a familiar voice cried from the cellar, "Pinkie Pie!!"

Pinkie, Ellie and I charged to the cellar door and down the stairs. Inside, Derpy was sitting on the concrete floor, covering her eyes, sniffling and her wings wrapped around her. Pinkie Pie was first to reach down the stairs, her eyes wide with worry.

"Derpy!" She exclaimed, running to the crying Pegasus and kneeling down. Derpy looked up at Pinkie, her crossed golden eyes tried to focus on the Pink Party Pony as they swam with tears, "Derpy, what happened?"

"I..." Derpy gasped, sobbing. "I... D-did... It... Wr-wrong...! I m-messed up!!"

Pinkie Pie, Ellie and I turned and saw Roseluck's split Cutie Mark.

Pinkie smiled and faced Derpy again, stroking her mane, "It's fine, Derpy!" She cooed. "It's your first time! No one's perfect!"

"B-but I w-wanted to d-do it on m-m-my own this t-time!!" Derpy cried.

"I'll help you today and you can take another shot at it next time." Pinkie Pie assured soothingly, "Is that okay?"

Derpy wiped her eyes and nodded, giving a weak smile.

"Pinkie Pie! Eleanor! Samantha!" Roseluck shouted, "What are you three doing?! Why are you teaching her these things? She doesn't know right from wrong, she's too stupid to know what she's doing!"

Ellie lowered her head to the point that her long bangs shadowed her eyes. She stood up and walked over to Roseluck. Suddenly, she grabbed Roseluck's Cutie Mark and ripped it all the way off with one swift motion. Roseluck shrieked in pain, looking down at her bleeding flank.

"Don't you dare call my Ditzy stupid..." Ellie spoke in a deep, spooky monotoned voice.

"She also said I was a... 'retard'." Derpy answered with an angry pout.

Ellie's right hand tightened into a shaking angry fist, as she swung her arm and punched Roseluck across the face, giving the rose-maned Earth Pony mare a black eye.

"HOW DARE YOU!!" Pinkie bellowed in her high pitched voice. She ran to the bottom of the stairs and called up, "Apple Bloom! APPLE BLOOM!!!"

The door opened again and the little filly came running down, "What's wrong? What happened?" She asked in an urgent tone.

Pinkie Pie's murderous glare moved to Roseluck and Ellie. Cuddled up to Pinkie was the teary eyed Derpy, looking nervous, unsure if she should stand up.

"Roseluck called Derpy a retard," Pinkie Pie answered in an acid voice. Ellie looked ready to kill someone.

Apple Bloom gritted her teeth as she slowly approached the trapped pony, standing next to Ellie, "Well that wasn't very nice..."

"Apple Bloom?!" Roseluck recognized, "You're part of this too?!?"

"Of course I am!" Apple Bloom answered happily, "I've gotta earn my Cutie Mark somehow!" Roseluck started crying, and Apple Bloom took a look at Derpy's tools, "We need to punish you for hurting our sweet Derpy." She chose a small hand axe and held it up, ready to swing--

"Wait!" Derpy cried, causing our attention to turn to her.

Derpy stood up and slowly walked to Apple Bloom, taking the axe from her. Her head still low, Ellie stepped back.

She turned to face Roseluck. "I'm going to do this on my own, like I said I was."

"D-Derpy!" Roseluck sobbed, as Apple Bloom and Pinkie Pie cheered, "Please, you don't know what you're doing!"

"I know just what I'm doing!" Derpy screamed. "I may not understand so good, and I may not talk so good, but I do know that I am going to chop you into bits and make you into muffins." She gave an evil grin and narrowed her crossed eyes, "Didn't I tell I love muffins?"

"You're going to kill me!" Roseluck cried, struggling violently.

"Yup," said Derpy, and she swung the axe, chopping off her left arm. Roseluck screamed even more as Apple Bloom rushed forward with a bucket to catch the blood, "I'M NOT STUPID!"

Derpy swung again and chopped off her right ear, "I'M NOT A RETARD!!"

She threw the axe to the floor, breathing hard and grabbing her scalpel again. She walked over to Roseluck's other Cutie Mark and managed to carve a rather neat circle around the rose. Roseluck was breathing heavily, sobbing still, her voice hoarse from screaming.

"Alright, Derpy!" Pinkie Pie cheered, "That was a perfect Cutie Mark cutting!"

Derpy smiled and nodded, "Thanks Pinkie! I'm glad to do good! I'm not nervish anymore!"

She gave a small dance, her hooves clacking on the cement floor. Then she suddenly slashed a deep cut in Roseluck's chest. It started to bleed freely.

Derpy gasped and covered her mouth, "Oh sorry! I'm so clumsy. Lemme make you better!" She took a needle and thread and started sewing the wound shut very roughly. Roseluck winced, shaking her head back and forth desperately, "Oops! Clumsy me! I messed up." Derpy cut the wound again, slicing the stitches, then started sewing it back up, "Oops!" She repeated this process a few times before just giving up and jabbing the needle right into the gash, "I just don't know what went wrong!"

"Hey Derpy," Apple Bloom spoke up, "I've got something special for you!" She held up a large pair of pliers, and Derpy took them.

"What should I do?" Derpy asked.

"Whatever you want!" Pinkie Pie answered with a bounce.

Derpy's evil grin returned, and she suddenly forced Roseluck's mouth open, "I wanna play dentist!"

She started ripping out Roseluck's teeth one by one with the pliers. The teeth landed on the floor with a little tink. Once Derpy was satisfied, she dropped the pliers and started chucking the teeth at Roseluck as hard as she could. They left scrapes and welts on her body.

"Derpy..." Roseluck started in a weak voice. "Please..."

Derpy pulled a lever to rotate the chair to stand vertically. Then she turned away from Roseluck, got on all-fours and started kicking her repeatedly with her back hooves. There were cracks as ribs were broken, and large bruises began to form.

"Careful, Derpy." Pinkie reminded, "We don't want to damage her organs too much!"

"Okie dokie lokie!" Derpy answered, and started kicking Roseluck's legs, breaking them in several different places. Pinkie giggled and turned to Apple Bloom.

"I'm so proud of her!" She smiled excitedly, "It's like having a little sister!"

"You sure did teach her good, Pinkie Pie!" Apple Bloom replied with a smile.

Finally, Derpy ceased her kicking, Roseluck's legs resembling a couple of strangely shaped sticks. Roseluck was still crying, but didn't even bother to scream or plead; she was too weak.

"Pinkie, should I finish up?" Derpy asked.

"If you feel you've had your fun!" Pinkie Pie replied.

Derpy fluttered briefly with happiness, and then took her scalpel again. She cut two horizontal lines, one below her ribs, and one above her pelvis. Then she connected them with a vertical cut straight down the middle.

"Don't you want to numb her first?" I asked.

"No." Derpy answered darkly, opening up Roseluck's abdomen, "I want her to hurt lots. She called me stupid."

"Revenge!" Pinkie sang, "It's best served in muffins!"

Apple Bloom came forward with her bucket and held it up for Derpy, who started pulling organs out.

"We return to the story of Lively Liver and his friends." Derpy started her story, pulling out the liver, "Bad Bladder and Sad Stomach form a new plan to make Lively Liver very sad."

She pulled out the bladder and stomach, "They want to make Laughing Lungs think that Lively Liver stole her favorite dress! This makes Laughing Lungs not laugh so good, and Lively Liver keeps telling her that he didn't do it! Playful Pancreas knows Lively Liver wouldn't ever do such a bad thing and tries to prove that he is good. And down comes Kind Kidney to tell that Bad Bladder and Sad Stomach do bad, and all the other organs know the truth. Helpful Heart comes over to make happy again, teaching them all about friendship and honesty..." Derpy dug out the remaining organs, including the heart, and dropped them into the bucket. As Roseluck's head lopped forward, Derpy said, "The end!"

"I think we've got everything we need!" Apple Bloom answered, holding up the bucket.

"No, we still need to skin and de-bone Roseluck and collect the rest of the meat," Pinkie Pie chirped.

"Oh yea!" Apple Bloom smiled.

"Did I do good, Pinkie Pie?" Derpy asked nervously, bowing her head and putting her ears back.

Pinkie gave her a huge hug, nuzzling her, "You did fantasterific!" She giggled, "I'm making you my new little sister! I love you, Derpy!"

"Yay! I have a sister!" Derpy cheered, overcome with giddiness.

"Welcome to the family, Derpy." I smiled, clapping my hands.

Then I turned to Ellie, who hasn't spoken or lifted her head. Derpy and Pinkie Pie turned to Ellie as well. Ellie walked toward the grey Pegasus and surprised all of us. She lifted her head, smiled and hugged Derpy, laughing. Derpy smiled and hugged my sister back with a laugh.

"Now let's get to work." Pinkie spoke up, holding up a knife, "We gotta make those muffins!"
