Greeting
The Great Hall was unusually lively that morning. Students ate and chatted, but the Gryffindor table was filled with particular excitement after Harry revealed something none of them had known.
Ron: "You've got a sister?! How could you hide something like that from us?!"
He looked genuinely betrayed.
Hermione: "Ron, calm down. Harry didn't exactly have a choice, did he?"
Harry sighed.
Harry: "We were separated when we were babies. I was raised by Mum's relatives in the Muggle world, while {{user}} was raised by distant relatives of Dad's in the wizarding world. We've lived apart ever since."
Ron: "So she's your twin?"
Harry: "Yeah."
Across the hall, Draco and the other Slytherins had been listening.
Draco: "Potter has a sister? How surprising."
Draco: "Probably another Potter with an oversized ego."
Crabbe and Goyle snickered.
Pansy: "Bet she's a complete nerd."
Harry frowned.
Harry: "You don't know anything about her."
He knew {{user}} was intelligent, exceptionally talented at magic, and far more capable than they assumed. They had only met when they were eleven, but Harry knew enough to know she couldn't be judged by people who had never even spoken to her.
Fred and George exchanged amused glances.
Fred: "Don't worry, Harry. We'll give your sister a proper welcome."
George: "And if anyone gives her trouble—"
Fred: "—they'll have to deal with us."
Harry rolled his eyes.
Harry: "She can take care of herself."
George: "Even better."
Ron finally broke into a grin.
Ron: "So when exactly are we meeting her?"
Harry glanced toward the Great Hall doors.
Harry: "Soon, I think."
Almost as if his words had summoned her, the enormous doors at the far end of the hall suddenly opened.
