Corvie sat in a compartment all by herself, staring out the window at the passing scenery.
"Hello, is this compartment open for seating?" asked a girl's voice.
Corvie turned away from the window, spotting a blonde girl with startling blue eyes. Behind her was a black-haired boy with stormy-gray eyes.
"No, it's okay," Corvie said. "Oh, thanks," said the girl. She and the boy moved forwards. An Indian girl joined them, and the three of them suddenly gasped.
"I heard a rumor that Harry Potter's long-lost twin was on the train," said the Indian girl. "You must be her." She stuck out her hand. "I'm Padma Patil. This is Theodore Nott and Daphne Greengrass."
Corvie knew that the latter two were children of known Death Eaters, but she didn't want to listen to anything that her father told her. "Corvus Potter," replied the girl. "Hang on," she said and then the eleven-year-old girl shifted. He became male. The others gaped at him–well, Theo didn't.
"I'm a gender-fluid Metamorphmagus, apparently," said Corvie, and there was a sudden knock on the door. A black-haired boy with glasses was standing there, looking furious. "Corvus," he hissed, sliding open the door. "What are you doing?"
"SItting with my friends," Corvie said coolly. "You must be Harry, my twin brother." The boy nodded. Behind him were another Indian boy, along with a pale, brown-haired boy and a redheaded boy who could only be a Weasley.
"Two of them are the children of Death Eaters, you idiot!" hissed Harry. "You need to associate yourself with the right sort of people."
"I'm fine where I am, thank you," Corvie said, shifting to female. She folded her arms and leaned back in her seat. "Can you sing well?" asked Padma suddenly. Corvie nodded. "I can sing a Muggle song for you, if you like."
She shot a pointed look at Harry and the two boys behind him. "Come on," said Harry in disgust. "She's a lost cause."
"Sing, sing, sing!" chanted Padma, Theo, and Daphne. The door slid opened again, and a round-faced boy poked his head in. "May I sit in here?"
"They're Death Eaters, Neville," said Harry angrily.
"Excuse me, but my parents are not Death Eaters," said Padma.
"I share the same parents as you, you twat waffle!" Corvie snapped.
"And our parents are acquitted Death Eaters, thank you very much," Daphne said, nodding at herself and Theo, who was scowling angrily.

"Sure, you can sit here," Corvie replied to Neville.
Corvie opened her mouth and began to sing.

I've been running through the jungle,

I've been running with the wolves–

To get to you,
To get you.
I've been running through the jungle,

I've been crying with the wolves–

To get to you,

Ohhh to get to you!

Corvie closed her as she sang, pouring her heart out into the song. Neville, Theo, Daphne, and Padma all gaped at her; both boys were glassy-eyed.
"Wow," Neville stammered. "You–you've got a beautiful voice, Corvie," he said. Corvie closed her mouth and felt heat creeping up her cheeks. "Well…thanks," she said.
"So…how does this gender-fluid Metamorphmagus thing…" Theo trailed off, looking a bit uncomfortable. "How does it work, exactly?"
Corvie brushed some hair out of her face.
"Well, put it like this." She held up one hand. "This is me when I'm female, right?" The others nodded. She held up her other hand. "So then this is me when I'm male, okay?"
They nodded again. "So, most of the time, I'm female," said Corvie. "I can't control when I shift or what gender I shift into, and I can't change what I look like. I look the same, just female or male versions of my parallel self. Got it?"
Theo and Daphne nodded; Padma shrugged, and Neville gaped. Corvie sighed, putting down her hands. "I'm female most of the time," she said. "But sometimes I have very male days. And I can't control when I shift. I also can't control what gender I shift into. Understood?"
Neville and Padma both nodded.

"So…" Padma sounded a bit unsure of herself. "What are you interested in when you get to Hogwarts?"
"Well, I'm mostly interested in Quidditch and Defense Against the Dark Arts," said Corvie, smirking. "I don't have my own broom, but I can still practice using the school brooms. Apparently my brother's a great flier on the broom. So I've got to practice a lot, or I won't be as good as him."
The talk turned from Quidditch to various other subjects as the train ride went on.

Corvie and the rest of the first-year students filed into the Great Hall. Draco Malfoy was talking haughtily to Harry and the two boys who were with him. Harry said something, and Draco went red, and then turned towards Corvie, who was male now.
"And you?" asked Draco icily. "Will you pick the right sort of wizard to hang around with? I can help you with that. You don't have to hang around with Muggle-borns–" Here he glanced distastefully at Hermione, Dean, and Lavender, who had become good friends with Corvie on the train ride–"or talentless filth like that." Now he sneered at Neville and Padma, who both went red in the face and glared at him.
Corvie didn't hesitate. "These are my friends, thank you very much," she said coldly, "and I'd rather you not insult them. I was raised by Muggles, you know? What's wrong with being Muggle-born? And I will have you know that everyone has a talent–or more than one. Just because Neville and Padma here haven't shown any particular talent yet doesn't mean that they don't have any."
Draco sneered, and then backed away, whirling around and storming into the crowd. Suddenly, the SOrting began. Corvie moved forwards. "Could you make sure that Harry goes first?" Corvie asked Professor McGonagall. "I'm not that good with huge crowds."
This was a lie, of course, but McGonagall didn't have to know that. McGonagall nodded. Students were called forwards.
Hermione, Dean, and Lavender were all Sorted into Gryffindor, as was Neville. Ronald Weasley and Seamus FInnegan–Harry's two friends–were Sorted into Gryffindor, too. Parvati Patil–Padma's twin sister–was Sorted into Gryffindor, as well.
Then it was Daphne and Theo's turn. The Hat hesitated before shouting, "SLYTHERIN!" for both of them. Corvie saw Draco and Blaise and the beefcakes get sorted into Slytherin, too. Then he watched his brother get Sorted…into Gryffindor.
Corvie was up next.
"Hmm, plenty of cunning, lots of daring," said the Hat. "Not Hufflepuff or Gryffindor, you say?" he asked. "Well, then…better be…RAVENCLAW!"
Corvi enjoined Padma at the Ravenclaw table, ignoring the shocked silence that followed him towards the table. The Ravenclaws, however, were all hooting and grinning. Two thirteen-year-old boys leaned forwards. Both of them were tall, with auburn hair and blue eyes.
"Leo and Lucas Levioskey," said the twin on the right. "Great to meet you. Hope you're a much more pleasant person to be around than the Boy Who Won't Shut Up Already over there."
Corviesnickered, knowing immediately that they would be great friends.
