Katrina Rose stood on platform 9 3/4, anxiously awaiting the Hogwarts Express. It was going to be her first day at this new school and she was very nervous. Partly because she had been expelled from her last school, but mostly because of her constantly changing hair. She was a metamorphmagus, meaning she could change her appearance by will.

   Well, in theory.

   She had very little control over her powers, so her hair went to "default" and changed with her emotions. Right now it was bright green, reflecting her anxiety.

   When the train finally pulled into the station, it was about 7:00 am. Katrina sighed, realizing she'd be on the train for hours. She looked at her cart, overflowing with her belongings.
How am I going to get this on the train?

   Katrina kicked the cart in frustration.

   "Now what did the cart do to you, love?" A rather smug voice called from behind her.

    That smug voice belonged to one James Potter. A young girl's dream, even at twelve. Was he handsome? Yes. Did he play sports? Yes. Was he widely known for his politeness and respect towards people outside his friend group? Eh...

   James smirked at the peculiar girl kicking her cart. "The cart didn't do anything, I just have no way of getting my bags onto the train. My parents just left." As she said this, she felt the familiar feeling of an egg being cracked over her head and knew her hair was bright pink. Her parents disdain embarrassed her to no end.

   Katrina's family were directly related to the Threstles, a famous pure-blood family. Her grandmother was Regina Threstle, who was said to be the great-great-great-great-great-great granddaughter of Rowena Ravenclaw, and all for her family since then had been Ravenclaws or Slytherin, since cunningness and wit went hand-in-hand. Her parents were very proud of their heritage, so naturally when Katrina was born, they were confused. One day her hair was black, the next orange, the next purple; it changed daily. Her parents thought someone had cursed their baby, and got worried.

   Upon taking her to St. Mungo's Hospital for Magical Maladies and Injuries, they were told she was a Metamorphmagus. Taken aback by this conclusion, her parents had shunned her everyday since.

    "You alright there, love?" His voice pulled Katrina from her thoughts. She turned to look at the boy and nodded quickly.

  "I'm fine. Could you help me with my bags?" The boy nodded, grabbing a couple hefty bags and heaving them onto the train for her. "Thanks." She said to him before briskly boarding the train, taking a compartment near the back.

   Katrina pulled a book from her pocket and started to read. The book was a muggle book called 'Hamlet' by a man named Shakespeare. It was quite good.

   Completely immersed in her harrowing story, she did not hear the gang of troublemakers walk towards her compartment.

   "Hey Moony, where should we sit?"
   "Near the back, where else?"
   "Don't be a git, Wormtail."
   "I am not being a git!"

   Suddenly her compartment door was opened. Katrina tore her book away from her face. In front of her stood four boys. One of them was the boy who helped her onto the train. He was quite handsome actually, with brown eyes and dark hair. Next to him stood an equally attractive boy with grey eyes and dark hair; he and the first boy were virtually the same height. Next to them, there was a smaller boy who looked frail, he had light brown hair and hazel eyes, with a scar running across his nose. The last boy was smallest, with brown hair and watery blue eyes.

   They all stared at Katrina. "Hello again, love-"

   "Don't call me that again, I'm no one's 'love'."

    James raised his hands in surrender. "Fine, I won't call you that. Could we sit with you?"

    Katrina took the boys' appearances in again. She shrugged. "Sure."

   "Brilliant! I don't believe we've been properly introduced, James Potter." He said sticking out his hand to shake. His cronies chuckled as they sat down.

   She took his hand, "Katrina Rose."

    The rest of the boys introduced themselves, before too long, Katrina knew these boys as Sirius Black, Remus Lupin, and Peter Pettigrew. They were all nice enough. After introductions, silence ensued. From what Katrina could tell from watching Peter sit on the edge of his seat, a question was inevitable.

   "So, what's with your hair?"

Katrina was slightly taken aback by this question asked so flagrantly, but answered anyway. "I'm a metamorphmagus, it's just a big word that means I can change my appearance at will." The boys' eyes grew wide. They whispered for a second, making Katrina raise an eyebrow.

   After much muttering, Sirius had to ask, "Why'd you transfer to Hogwarts before second year?"

    Katrina thought about this for a moment,
"I transferred because I was expelled from Beauxbatons. I don't like to talk about it."
Sirius nodded before getting out a deck of cards to play with James. They were okay with her being "bad" enough to get expelled? Katrina smiled to herself. They aren't annoying prats...

   They spent the rest of the ride laughing and getting to know each other and Katrina was genuinely convinced these boys were going to be her good friends.

   But, that was four years ago...
