"No."

"Please, Harry -"

"No."

"If you could just hear me out for one second - "

"What part of 'no' are you not hearing?!"

The girl who looked suspiciously like him without glasses or a scar pouted, "I'm telling the truth, though!"

"Where's your bloody proof?" Harry didn't wait for an answer and tried going back to reading Quidditch Through the Ages while the girl began to do exactly what Dudley always did when he wanted something and was being denied it. Her wails echoed in the Great Hall and everyone turned their heads towards the source of the commotion. Harry furrowed his brow and pulled the book closer to his face to divert suspicion.

It didn't work.

"HEEEEEEEEEEE'S IGNOOOOOOOOOOORING MEEEEEEEEEEEEEEEEEE!"

"Silencio!"

Immediately, the girl's wailing ceased and Harry smiled with satisfaction that all of the practice in Charms had not gone to waste. Hermione looked torn between telling him off for using magic in between classes and kissing him for silencing the strange girl who had just shown up in front of them five minutes ago. Everyone went back to their breakfast now that the commotion had ended. Even with her voice silenced, the girl still continued to open her mouth as if she could break the charm with enough sheer force of will. Instead, Harry could see that her face was turning a lovely shade of puce that Uncle Vernon would be jealous of.

Ron just sat down a moment later and looked at his best friends for an explanation.

"She's been trying to convince Harry that they're twins," said Hermione.

"Half twins," Harry corrected her and the apparent half-twin in question scowled at him, "You grew up with Fred and George, Ron. Can wizards have half-siblings?"

Ron took one look at the girl - who now looked as though she were trying to Transfigure her face into a blueberry - and snickered. He said, "Why would it be different if we were wizards?"

Thump!

They all turned their heads towards the noise and saw that the girl had crumbled to the ground, finally succumbing to asphyxiation.

"Blimey," Ron leaned over the table, "Reckon we should poke her?"

"I'm not touching her with a ten foot broomstick!" Harry declared vehemently.

"Honestly, this is becoming ridiculous," Hermione sighed, "Shouldn't we tell Dumbledore about all these girls claiming to be your sister, Harry?"

"I would, but I don't think I'd like the answer..."

Author's Note: How can someone have a half twin? Just think about that for two seconds...
