My first fanfiction! I should probably mention this has focus on an OC but I couldn't only put one twin in the character space. This chapters really short but I'm still getting used to the controls. I will get better. So read and Enjoy!

First day of school and already horrid. The Slytherin's hated her and the Gryffindor's mistrusted her.

How had pure blooded Katherine Nott managed not to get into Slytherin? She got into Gryffindor, no less. Her father was furious. He'd refrained from sending a howler-thank Merlin-however that didn't stop her from being ready and willing to rip the head of the first person who had a go at her.

She was just a little stressed.

Just as she was mulling over the stress relief benefits of ripping someone's head off, a water balloon crashed onto her head. Without thinking she aimed a stunning spell in the direction the balloon had come from.

Benefits of coming from a pure blood family she supposed. She was way ahead in all the practical parts of class. Especially offensive and defensive magic. Her father taught her offensive, 'passing on a gift', and her mother taught her defensive to keep herself safe. At least, she used to.

A small part of her acknowledged that there were at least two voices up there and she could only hit one. With a yell whichever one she'd hit toppled to the floor in front of her.

Good thing it wasn't too high up, she noted. Investigating the person at her feet.

"Oh, damn it!" She snapped as she recognised one of the Weasley twins, as in someone from her own house, who also had constant back up.

Just as she was contemplating running the other twin ran towards them, having come down from their hiding place.

"Fred!" He yelled towards his brother, who groaned slightly, regaining control of his body.

"Oh, Merlin, what was that George?" He asked, rubbing the back of his head.

Katherine, much to her relief, went unnoticed. She slipped away from the pair, ducking behind the first corner she saw. Leaning against the wall she signed and slid to the floor. Way to go instincts, she was not going to survive in Gryffindor, the rest of her house was going to kill her if she kept this up.

"I don't know," She heard George replied, "That balloon we dropped must have hit one of the more temperamental students."

"Right," Fred agreed, "So next time, we make sure not to stand so close to the edge."

"Then they can't hit us," George finished. Katherine heard their footsteps coming her way. As she stood up she remember her hair was wet. She quickly made her way down the hall, letting down her hair and shaking it out. She began running her fingers through it to pull out any broken balloon bits.

She got the edge of the corridor just as the twins rounded the corner. She made the mistake of looking up at them. Her eyes widened and she took off at a run. It wasn't like her to run from a fight but they had friends, she didn't. Both of them had been focused on her dripping hair.

That night at dinner Katherine sat alone, much like breakfast and lunch. Though it probably had something to do with coming to all the meals early to try and avoid her house. She was trying to work out how to avoid the twins considering they had all their classes together. So far she had nothing, she didn't know how to avoid people, her father had always taught her to face things head on.

Other students started coming through the hall, Katherine picked up her bag and headed out of the room. Just in time to bump into a red headed boy. To her relief it turned out to be Percy Weasley rather than the twins, he didn't say anything to her and she carefully made her way back to Gryffindor tower, ensuring neither of the twins were there before she entered. This was going to be a long year.

Katherine headed up to her dormitory as soon as she saw the two red heads entering the commonroom.

The next day Katherine ate breakfast at the same time as everyone else. She'd decided she couldn't constantly be ducking around corners and she would not keep trying to hide who she was.

Despite this, she wasn't surprised when people gave her a wide berth. She was even less surprised when she saw the twins enter the Great Hall, their determined eyes focusing on her.

They made their way towards her and, apart from the flick of her eyes when they entered the hall, she gave no sign that she saw them.

"You hexed me yesterday," Fred said as they sat down, filling their plates.

"You dropped a water bomb on me," She countered, continuing to eat.

"That was an accident," put in George.

"And I didn't tell anyone," Katherine replied.

"How did you know that spell? Isn't that a bit advanced for someone on their first day of school?" Fred asked, changing the subject.

"My father taught me," she said easily, finishing off what she had on her plate. The twins didn't say anything, she imagined they were contemplating questioning her about her family. Unfortunately for them her schedule wasn't about to change for their interests.

"I'm going to classes now," she informed them, walking away from the table.

Apart from classes, in the majority of which she now sat next to the pair, Katherine didn't have any more interaction with the twins until Friday. This was about when she decided it had probably been a bad idea to get involved with the pair at all.

Despite being short, hoped you liked it. It's only going to get better if you review, and I practice but still. I want your opinions. Also I plan on changing parts in the book for my own preference so a few things you can help with.

1. Is there anyone you don't want to die? (Unless their death is vital to the plot, eg. I can't save Dumbledore)

2. If theres anything you think the map should say to the twins when they find it, comment and I'll consider it.
