A lot of people think Sweetiebelle is Rarity's sister. Wrong. It started on a rainy night, cold and feirce. Rarity was inside watching the rain pour. "Wow... It's really pouring out th-", Rarity was interupted as she saw a box outside. Rarity didn't know why... But it caught her attention almost instantly. Rarity HAD to investigate.
Rarity got her pretty purple rain coat on, and walked to her door. She sighed, "Okay... It's just rain... So long as it doesn't mess up my mane "ill be fine." She said, opening the door with her magic. She walked over to the soiled box, her hooves splishing on the ground. She noticed the tarp over it. How hideous. She lifted the tarp, and nearly had a heart attack. Inside... Is a shaking and crying filly.
Rarity instantly picked up the box with her magic, and took it inside. "What is a little filly like you doing out there in the storm?" Rarity said, examining for some sort of note. She picked up the crying filly, and wrapped a blanket around her. She looked back into the box, and found a note and toy.
She gave the white coated, purple/pink maned filly the purple pony plushie, and picked up the note. 'Dear who ever finds this filly, I'm sorry I couldn't keep her for fear of my own and her own safety. If you find this and she's already passed... I'm sorry... It's not my fault. Her name is Sweetiebelle... Take good care of my baby.' Rarity finished the note, almost crying over it. She held the filly close until stopped crying.
She put the filly in the high chair SHE was fed in as a filly. She went into her kitchen, and opened the fridge. She searched until she found some milk and a bottle. She heated the milk, and fed the baby Sweetiebelle. "I feel so sorry for this filly!" Rarity thought aloud.
When Sweetie was done, she took the bottle out, and handed it to Rarity, who levitated it to the table. Rarity put the baby on the floor, and sat and played with her. She'd pin her down softly, and tickle her. They'd play peek-aboo, and take turns doing something with magic, even though Sweetiebelle couldn't really use magic, Rarity would always cheer and clap.
Sweetiebelle would try to use her magic, and then she'd give up and make a frown, but Rarity always made her smile again.
When it was bedtime, Rarity lifted the filly up, and took her to her bedroom. She placed the filly on the bed, and climbed in with her. She moved the blanket over them, and turned the lights off.
