Soon, Rarity found her way home. "Sweetie, I'm back!"

"Sis?!" yelled Sweetie Belle, running into the room and latching herself to the unicorn's foreleg. "It's been a week! Where have you been?! I thought you weren't coming back!"

"Oh, Sweetie, I was just... at a fashion expo. I'm sorry I forgot to tell you," Rarity lied.

"Well, you're back now, and..." she said, stopping as she looked up. "Wh-What happened to your face? Are you okay?"

"Oh... Don't worry about it."

Sweetie Belle smiled. "Not sure how you do it, but... even with those scars, you still look pretty."

Rarity giggled. "Oh, Sweetie. These aren't just scars... They're beauty marks."

"Beauty marks?" asked the foal. "Well, they do show character, but... I wouldn't say beauty."

Rarity's eye twitched. "Well, they are."

"If you say so..." said the foal, looking confused and uncertain.

Rarity nodded. "If you like, I could draw up some marks for you. I promise they won't hurt," she said with a smile.

"Uh... N-No thanks."

"Awww... Why not?"

"Because, I don't wanna look... like... that," said the foal, pointing at Rarity's face. "I don't want scars."

"A-Are you saying it looks bad?!"

The foal cowered slightly, ears dropping as she took a step back. "U-Uh... M-M-Maybe?"

Raritys eyes started filling with tears.

The foal gasped and hugged her sister. "But, they look good on you, sister. Really."

The mare started balling. "You think I'm ugly!"

"No no. I don't think you're ugly, honest."

"Yes, you do!"

"No, I don't. Uh... I-If you wanna give me some, y-you can..."

"R-Really?" Rarity asked, her face soaked in tears.

"Yes. But I get to choose where and how much I want."

"O-Okay..."

"Well... If I had to have scars, I'd like to have one on either side of my mouth going straight down. Like a doll."

Rarity's mouth curled up into a smile. "A doll, you say?"

Sweetie Belle nodded. "Doll's are pretty, right? Don't you think I'd look prettier with scars like that?"

"Why, yes, you would. Oh, you would make the prettiest doll in all Equestria!" Rarity said with a broad smile.

"Hey hey... I don't wanna be a doll. Just look like one."

"That's what I meant..." Rarity said. "Can I do them now?"

"Sure. How will you do them?"

"Well, I'll need a small knife, some bandages, and the stove... Shall we move to the kitchen?"

Sweetie Belle gulped. "O-Okay..."

The older mare led her sister into the kitchen, getting out all they needed. She boiled some water and stuck the knife in it. The foal was sweating nervously.

"This is just to clean the blade. Don't want anything icky getting in you," Rarity said with a girly ew face.

"W-Will this hurt?"

"Not too much, deary," the older sister said, coming up to Sweetie, holding the knife.

Sweetie gulped and nodded. "A-All right. I-I trust you."

"Now, please lay down on the table."

Sweetie Belle nodded. "Be gentle," she said, looking up at the table. "Um... A little help?"

Rarity giggled and helped her little sister up. The foal then laid on her back, breathing to try and calm her nerves. Rarity used her magic to hold Sweetie in place as she quickly made the first cut down the left side of the foal's mouth. The foal whimpered as tears filled her eyes. Rarity quickly did the other side and pulled Sweetie into a hug.

"Oh, Sweetie Belle, I'm sorry. I didn't mean for it to hurt that much."

"I-It's not so bad... a-actually..."

"I'm still sorry," Rarity said, kissing her forehead a few times.

"W-While I'm s-still used to it... How about t-two more?"

"Two more?"

The foal nodded. "From below the center of my lower eyelid down my cheek and stopping just before the neck."

"Are you sure?"

Sweetie nodded. "Just... Be careful."

"Alright... Lay back down."

The foal nodded and did as told. Rarity slowly got ready to make the cuts, and quickly did both of Sweetie's cheeks. The foal stifled cries and, when it was done, exhaled deeply. She touched her cuts and winced, sniffling.

"N-Now, what?"

"Now, we just leave them alone. They will come out quite nicely."

"Wh... What about the... the blood?"

"Just keep it wiped up."

The foal nodded as she stared at her bloody hoof. "D... Do I look... pretty?"

"Oh, absolutely beautiful, little sis."

Sweetie Belle smiled. "So... cuts and scars make somepony... prettier?"

Rarity posed and smiled. "Why, yes! That's exactly right!"

"Wow... That's way easier than making a dress, isn't it?" asked the foal. "Think we should should others this new technique?"

"Hmmm... Yes. But only show special ponies, okay?"

"What you mean by 'special'?"

"Ponies who really need it."

"How can we tell who needs it?"

"I'll help you pick, okay, sweetie."

"Okay," said the foal, blood dripping from her wounds.

"Now, is there anypony that needs... How do I say it? Is there a pony that needs to learn a lesson? Somepony who's mean? Maybe somepony that needs to be taken down a peg?" Rarity asked.

"Um... Well... There's... two..."

"is one worse than the other?"

"Well... Diamond Tiara."

"Oh, Filthy Rich's kid?"

Sweetie Belle nodded. "She doesn't know what real beauty is. But, we do, right?"

"Oh, yes... Say, why don't you go get her?"

Sweetie Belle smiled and hopped off the table, heading for the door. "Wish me luck."

"Luck, Sweetie."

Author's Notes:

I had already edited this chapter but it didn't save. That's why when I published it it had the unedited stuff like grammar and the RP time stamps.
