I do not own Harry Potter.

Poor Harry.

It took another week for Hedwig to return with Dumbledore's reply. Harry couldn't help but feel annoyed when he read the letter.

Dear Harry,

Yes, I feared that this would happen. These girls are called Mary-Sues. You must avoid them at all costs. I am sending along a coin to you. Just place the coin on the ground. Hopefully she will be able to help you. After she has appeared, explain that she is there to help you to the Dursley's.

Dumbledore.

Harry stared at the letter in shock. His house was filled to the brim with strangers and all Dumbledore could send him was a coin. A coin!

A knock on the door startled Harry out of his thoughts. The door opened and a girl with black hair and green eyes came through.

"Harry, Auntie said that dinner's almost ready," she said.

Harry pushed his glasses up and stared at her. Auntie? Where did she get off calling Aunt Petunia, Auntie? And if she was his sister, why didn't she have glasses?

"Um. Alright. I'll be right down," Harry replied. The girl, who called herself Harriet, shut the door and went back downstairs.

Harry went back to staring at the letter. In one hand he held the coin. He shrugged and placed the coin on the floor.

"Here goes nothing," he muttered.

In a blinding flash of light, the coin turned into a girl. Not a teenage girl, but a little girl. Literally.

The girl and Harry stared at each other. Finally the girl blinked and asked in a high voice, "Who the hell are you?"

"I'm Harry," Harry said uncertainly.

"Oh, so you're the bloke with the infestation," the girl sat on Harry's bed and made herself comfortable.

"Are you the she that Dumbledore was talking about?" Harry asked.

"Yeah, I suppose." She said. She jumped down from the bed and began poking around Harry's room. Harry was reminded of a house-elf because of the way she looked around. She had the pointy ears too.

"Not to be rude, but what are you?" Harry wondered aloud.

"Oh? Me? I'm an elf. Phew! What smells in here?" Her head popped out of Harry's closet.

Harry shrugged his shoulders. "How are you supposed to help me?"

"Oh, that. I suppose we should talk about that," She walked out of his closet and pulled a sock off her blonde head. She made herself comfortable on Harry's bed again. "Just give me two minutes and I can have them all killed."

"Killed? No, I don't want them killed, I just want them gone," Harry said quickly.

The girl looked disappointed. "We could always say that Harry Potter isn't you. Then they'd leave. Or we could go with Dumbledore's original plan."

Harry looked at the girl, "He had an original plan? Why didn't you tell me?" Harry stood up.

"Because I wanted to kill them." The girl stood up on Harry's bed and crossed her arms. She didn't look very menacing. In fact, she looked more like a cross kitten.

Someone knocked on the door and opened it. It was "Harriet" again.

"Harry, what's all the racket?" She asked before she noticed the little elf. "Ooh! How cute! What's her name?"

The elf scowled at her and bared her teeth. When "Harriet" went to pat her on the head, the elf snapped at her.

"Harriet" snatched her hand back. "Harry, dinner's ready," she said then left.

Harry looked at the girl. "What is your name, anyway?"

"Leo," she replied. "So, are you going to keep me?"

Harry thought for a moment, "Let's see how you do at dinner. What's Dumbledore's plan?"

Leo beckoned to Harry to come closer. She whispered in his ear and Harry's eyes widened. When she was finished, Harry stepped back and looked her up and down. "But you don't look anything like me," he protested.

Leo scoffed. She wiggled her little nose and her pointed ears disappeared. Then, her blonde hair turned black and messy. She waved her hands and a pair of black-rimmed glasses appeared. She put them on She looked like a miniature Harry Potter.

Harry nodded and picked her up. He balanced her on his hip and went downstairs.

"Here goes nothing," Harry muttered.
