Derpy was laying on the floor with a painful look.

Pinks ran over to her and knelt down, gently pulling the mare into her lap. "Derpy? You okay?"

"I.... wanted water. My body feels numb..." Derpy said in a dull voice.

The pink mare nodded. "R-Rarity?"

The unicorn poked her head in, levitating a glass of water. "I got it here," she called, holding the glass out.

The pink mare took it and brought it to Derpy's lips. "Here you go, sweetie."

Derpy tried to drink it fast but almost chocked.

"Slow down, okay. We're not gonna run out of water."

Derpy nodded and slowed down.

"I'm sorry I left you, Derpy. Won't happen again, I promise."

Derpy smiled till she saw Pinkamena's face. "R... Rarity did that to you?" she asked.

The pink mare nodded. "You like?"

"You did... For me?" Derpy wheezed.

Pinks nodded, stroking Derpy's mane. "Yeah... Now, we match."

The mare smiled with her eyes closed.

Pinks then leaned in and kissed her forehead. "Derpy... I just want you to know... I do think of you as... more than a pet..."

"You do?"

The pink mare nodded. "Yes. I do."

Derpy smiled wider. "I love you... Pinkie..."

"I love you, too, Derpy..."

The gray mare fell asleep with a smile.

Rarity silently got up and left the two alone, headed home.

Diamond trotted into the kitchen for a glass of water. When she got there, she saw her Filthy Rich doll sitting at the table.

She looked around the room before staring at the doll. "How'd you get here?"

Suddenly, it looked down at her. "Tiara. What are you doing here? You know you're to stay in your room when we have business guests," he said in a scolding kind of tone.

The foal gasped. "B-But... Y-Y-You're dead."

Diamond blinked and found herself in her old home with her parents throwing one of their adult parties she was always told to stay in her room for. She looked in a mirror and found her old self, tiara and all. "Oh, goodness, Filthy. Why is she not in her room?" asked Gemstone, her mother.

Diamond gasped and looked at her mom, backing up. "I-I'm sorry..."

"Young filly. Go upstairs or we won't buy you that new dress you wanted," her mother warned.

Diamond gasped and ran upstairs.

When she opened her door, she found herself at one of the beauty paegents her mother forced her to enter in. She sat in front of a mirror as her mom set a tiara on her head. "Now, go win first place for mama, okay, Tiara?" her mother said, before leaning in. "And if you do, I'll buy you those toys you wanted..."

Diamond smiled weakly before stepping onto the stage.

As she did, she found herself at one of her father's formal dinners. "Sit up, Tiara," he said.

The foal whimpered and sat up straight. "S-Sorry..."

"Hooves off the table, Tiara."

Diamond did as asked. "I apologize, father."

"That's better, young filly. Now, if you're good, I'll get you a new Tiara tomorrow," he said, patting her head.

"Yes... father..."

"Now, be a good filly and get daddy's friends a bottle of wine from the cellar, okay, Tiara?" he asked.

"Yes, father," she said weakly, leaving the table and heading down to the wine cellar.

When she got to the bottom of the stairs, the door slammed shut. She let out a gasp and spun around.

The door was locked from outside as her mothers voice came down. "I've told Filthy to lock this door for years," she told a friend.

Diamond began banging on the door. "Let me out!"

But no pony heard her.

She slid down into a seated position and cried. "Please! Let me out!"

Diamond felt hours pass till the light of morning shown through the window as the door opened. "Tiara? What are you doing down here, little filly?" her mother asked, sounding mad.

"F-Father asked me to get some wine for him and the door closed."

"Oh... Well I'm sure we can do something... Perhaps a shopping trip?" she asked with a forced smile.

"Um... Okay..."

"What shall we get you, Tiara?"

The foal gritted her teeth slightly. "How come you never say my first name?"

"Well... Tiara is shorter," Gemstone said.

"But... my name's Diamond. And why don't you ever call me something cute like "sweetie" or "honey"? It's always "little filly" this or "little filly" that."

"now tiara stop this little fit right now" her mother scolded

"My name's... not... TIARA!"

"Yes, it is, young filly."

"It's DIAMOND! Call me DIAMOND!"

"Tiara! Stop this tantrum right now!"

"NO!" the foal yelled back.

Gemstone raised a hoof and stomped it down. "Tiara!" she yelled.

The foal glared at her mom before trotting passed her. "Thanks for letting me out," she spat.

"Get back here this instant, Tiara!" Her father yelled

Diamond stopped moving. "Who's... Tiara?"

"You are"

"Mmm... I don't think so."

"Now, stop this right now, Tiara!" yelled her father as a door opened and Rarity and Sweetie Belle watched her with warm smiles.

The foal eyed her parents and then Rarity. She then smiled and made her way to the white unicorn. "Good-bye mom and dad. Unlike you, Rarity actually cares about me."

"You'll always be Diamond Tiara so long as you bear that cutie mark..." yelled Filthy Rich as Diamond got close to Rarity.

The foal stopped. "Perhaps... But I don't want you as my parents anymore," she said before resuming her trot towards Rarity.

"We gave you the tiara that got you that mark, Tiara," called Gemstone.

"Then... TAKE IT BACK!!!" yelled Diamond, tearing off her tiara and throwing It to the floor. She continued on towards Rarity.

As she got close, Rarity spoke. "If only you had a better cutie mark..." she said, turning away.

Diamond stopped in front of her and felt her flank. "New... Cutie Mark?"

"Yes... Too bad..." She then began walking away.

"W-Wait!" she yelled, running after her.

"Good-bye, Diamond Tiara," Rarity called, walking into a bright light.

"NO! RARITY! WAIT!!!" she cried.

Diamond bolted upright in Rarity's bed, tears still on her face.

She looked around. "R-RARITY??!!!" she cried again.

She saw a note on the bedside table. 'Dear, Diamond. I had to go out for a bit.'

She grabbed the note and read it closer. "H... Hurry back..."

As she did, she remembered her idea in her dream; New cutie mark.

She breathed heavily before climbing out of bed and heading down the stairs and into the kitchen.

As she looked around, she saw Rarity's carving knife laying on the table.

The foal went over to a chair and dragged it next to where the knife was. She then hopped up on top and grabbed the knife in her mouth. When she tried to cut her cutie mark, she couldn't reach.

She groaned and jumped down. "Sweetie?! Could I have some help with something?!"

"What?" Sweetie called, stepping into the room.

"I need you cut an X over my Cutie Mark."

The filly jumped up next to Diamond. "You sure?"

Diamond nodded. "Yes. Do it," she said, dropping the knife in front of Sweetie, who took it.

"Lay down on your belly," the white filly instructed.

Diamond did as told.

Sweetie quickly slashed an X on one side of Dolly's flank.

Diamond whimpered. "N-Now... Th-The other side."

Sweetie did it, too, and pulled out some bandages.

"Oh, it stings, she whimpered.

Sweetie Belle bandaged Dolly's flanks. "Sorry... Hey, if Rarity's now your mama... wouldn't that make me your aunt?"

"I... guess?" said Diamond.

Sweetie smiled darkly.

"What are you thinking?"

Sweetie slowly moved closer to the other filly. "I want to play makeover..." she said.

"U-Uh... How so?"

Sweetie giggled as she dragged Dolly to her room.

The front door opened and Rarity entered, looking around. "Sweetie! Dolly! I'm home!"

"Sweetie's room!" yelled Diamond.

Rarity raised an eyebrow as she walked up to her sister's room "What are you two up to?"

"I'm getting a, uh... makeover?"

Rarity walked into the room.

"Hey, mom," said Diamond. "What's up?"

Rarity looked at her. She was wearing a cliche, pretty-pretty princess dress and a lot of makeup. Rarity raised an eyebrow. "Sweetie's work?" she asked.

"Uh-huh," said the foal, looking at herself.

"We'll go take that off and put your dress on, okay?" Rarity said, looking for her sister.

"Okay, mommy."

"Sweetie Belle?" Rarity called, looking for her sis.

Sweetie Belle peeked out from a closet. "Yeah?"

"Did you dress her up that way just to humiliate her?" Rarity asked with a smile.

"Maybe..." said Sweetie Belle with a grin as she looked up and away slightly.

"Well don't do that to Dolly, okay? If I get another to make pretty, I'll let you humiliate her, okay?" Rarity said with a smile.

Just then there was a knock at the door.
