A/N: Everyone out there reading this story um… This is the only author's note I'll put in this story. You guys probably aren't reading this but I still have to tell you guys. I promise to make this story a better written one. My previous one sucked- even though it's my favourite one. This story is really AU and starts in Harry and Jet's Fifth year. Enjoy :)

"Hahaha! Come on Mr. Filch, come and get me." Jet Smith was being chased by the caretaker Argus Filch.

"Come back you wretched girl, come back. You turn my cat back to its normal colour." Jet ran faster. She laughed out loud.

"Oh NO Mr. Filch! She's showing her festive colours. Plus she doesn't seem to care. Quite frankly I don't know why YOU care. Why get your knickers in a twist? Or is it boxers Mr. Filch. You could be a briefs man. Yeah you look like one." Argus Filch lunged at her once again, but Jet dodged.

"You insolent little rat! I will have you this time. I will take you to the Headmaster and you and that wretched Peeves will be expelled once and for all!" Jet laughed.

"Well technically, Sir, if you are expelled it is once and for all." She looked serious and Filch looked at her closely.

"Detention 9 o'clock Saturday! Don't be late!" Jet looked at him.

"Yeah I'll bring a couple of dungbombs and more jinxes up my sleeve for your darling cat." Argus Filch screamed and started chasing Jet around. Jet ran amongst the throng of students.

"Coming through, coming through!" Most of the girls sighed at her boyish and un-girly ways.

"Watch where you're going Smith!" Said one of the girls. Jet did a double take. She walked backwards and came face to face with the person who spoke.

"Sorry, Parkinson," she frowned down at her, "But you see my eyes hide the ugly people, mostly for my benefit. Sorry my Sight must've deleted you." Most of the students laughed but Parkinson held her nose up high and walked on.

"Where is she? Where is she?" Filch was pushing his way through the students.

"Uh oh, that's my cue. Bye guys." No one waved back. No one acknowledged her, no one even knew her name.

"You insolent girl, come back here!" Filch was still pushing his way through. Jet continued laughing and running. She reached the portrait and said the password between pants.

Jet yelled the password and scrambled through the portrait hole. She came in the warm common room and sat down on a comfy armchair. She looked at the fire and recalled her day's events.

She woke up in the morning and went to classes as usual. No on spoke to her, as usual. Even the nicest girl in her dormitory, Hermione Granger, didn't talk to her. Not that Jet was allowed to talk to her or any of the girls in Gryffindor. Her mum made her promise not to make friends with any of the girls or else 'the future would change' and no one wanted that to happen. Apparently Jet was going to find out about everything in due time. When classes finished she got bored and wasn't in the mood for eating. She set out to find Mrs Norris and change her colours, again. This time she changed her fur to orange and black as it was the a month before Halloween. Mr Filch came after her again. He always was and kept giving her detentions. He tried getting her expelled but Professor McGonagall wouldn't allow that. Her favourite pupil was Jet Smith. Jet knew that professor McGonagall liked the way that Jet teased Mr Filch and his cat. After all he was the teachers' worst nightmare. He was always complaining about students and their behaviour.

Here she was now, alone, sitting in the common room. She wasn't arsed to do her homework but she had to do it or else Snape would get pissed at her, again. She couldn't concentrate on her homework. She looked around the common room and saw the warmth everyone was radiating. Everyone had friends. The most famous group was Potter's group. They were always getting up to no good. Unbeknown to them, Jet had been in all of their adventures. Her mother had told her from a young age, when she went to school with him, to protect Harry Potter. So far he didn't need any help. Last year going into the maze wasn't possible. She could have saved Cedric. She cried for nights because she thought she could have been there to prevent his death. Maeve, her mother, had told her not to worry. It wasn't her fault.

Jet was a loner. She had no friends and no one talked to her. She didn't mind thought, or so everyone thought. She always was happy and hyper and pranking people she didn't like. Her number one target was Filch. She also liked, on occasion, pranking Crabbe and Goyle. They were the stupidest year fives anyone knew. Despite all of this fun she had she didn't have a close friend. Someone she could share secrets with. No one went near her because she got so many detentions they were afraid they would get detentions as well. The guys never noticed her because she never talked to them and always kept silent. Someone came in the common room and interrupted her thoughts.

"That was awesome! Did you see his tongue when we gave him one of our ton tongue toffees? Like that whale of a cousin Harry's got." Fred Weasley was waving his arms about in excitement. Jet could always tell them apart. Fred Weasley was louder and had a deeper sort of voice while George, was hyper, but he had a soothing voice and he also had a posture that made him seem a bit shy. No one could tell them apart because these tiny details only Jet saw. She shook her head at them and sighed. Everyone thought that the Weasleys were the 'prank masters' but really Jet had achieved more than them. Zonko even had a contract with her. She made them sweets that made their customers shake until they collapsed. She had made so many things that she had to keep a 'recipe' book. She had memorised most of it but she kept it mostly for the benefit of her kids. If she had any because if everyone continued to ignore her like that and no guy noticed her then she would have a tough time having children.

"Yeah it was! Draco Malfoy's tongue just went wooop." They laughed again. Jet sighed. They were so immature. They always thought they were better than others. They had passed her so many times and they never even said a 'hi'. They had even served detention together sometimes. She went back to doing her homework and the night passed uneventfully.

"Mr Potter I will not tolerate this. You will sit down and speak no more of this nonsense."

"But professor…" Harry started.

"No buts, Potter. I am here to teach Defence Against the Dark Arts not mythology." Professor Umbridge spat at him.

"Actually professor may I intervene." Everyone stared at Jet. She stood up and looked tiny in the big classroom. "Mythology is about things that don't exist. Lord Voldemort does exist so technically he cannot be mythology." Everyone stared at her.

"He has not returned Ms Smith. Potter is speaking nonsense." Jet started going red. If you knew her well that mean that she was getting angry.

"I believe him." She said quietly. Professor Umbridge looked at her.

"What?" She asked her.

"I said, I believe Potter. Always have, always will."

"Detention Ms Smith." Jet wasn't going to have this. She turned to face the whole class.

"Don't believe Lord Voldemort is back. When your parents get murdered in their beds at night and the ministry gives you bullshit as a cover up story and you swallow it all up well then you guys are a bunch of idiots. Or maybe when your best friend dies will you then believe that Voldemort is back. But then it's too late. And then you die, should have believed Potter shouldn't I, you guys will be thinking. But oops it's too late cause you're dead." Harry looked at her in admiration. From next to him Ron could be heard saying,

"Bloody hell, who is she?" Professor Umbridge pointed her finger at Jet.

"Ms Smith. Detention next week for a month. Monday, seven o'clock in my office, do not be late." She went to sit down but Jet was not finished.

"Why can't you believe he's back Professor. Someone died! As Potter said, did Cedric just die… just like that?" She screamed at her.

"Ms Smith!" Umbridge roared. "You will not speak about things you are too young to understand about."

"I doubt Ms that because I'm too young that I can't understand. Potter has done things you haven't even heard of. All of you at the ministry just think it's a story to give him fame. Do you think he likes fame? Tell me do you?" Jet said staring intently at Professor Umbridge.

"Ms Smith if you do not stop talking this instant I will…" Jet gave a dry laugh.

"Save it, I'm leaving." She pointed her wand at her bag and it levitated behind her.

"Step outside that door…." She was warned. Jet stepped over the line that divided the corridor and the class and looked back.

"Oops." She said and laughed. She walked up to her dormitory where she could think in peace.

She sat on her bed worrying. She had never done anything so rational before. She shouldn't have done that but yet Umbridge was being a right pain in the arse. She knew her mum would understand. She always flew off in rages like that. She put her hands behind her head and laid down on her bed. Her thoughts went to her father, Sirius Black. After 11 years of not having an idea of who her father was, her mother finally told her. He was the murderer that broke out from Azkaban. Now he was acting like a father to Harry Potter.

"Stupid Potter. Gets everything he ever wanted." Jet grumbled. She didn't have anything against Harry it's just everyone went on about how unlucky he was living without his parents and having to have Voldemort after him. Despite all of that he had a great group of friends and Ron Weasley invited him over to his house every summer. What did Jet have; a mother who suffered from mild depressions now and then, a father who was a no show all her life, no friends, and powers that could get her killed. She always thought of going to find her father but her mother had told her many times that the future should be changed only for the best. Well wasn't finding her father changing the future for the best. Jet couldn't help but wonder what kind of work her mum did. She sometimes poured over books reading and re-reading. She never read the title but she knew that they were important in her life.

That night Jet stayed up in the common room reading one of her favourite books her mother had bought for her on a trip to Australia; 'On the Jellicoe Road'. She had read it so much that the spine was creased. She didn't hear the Weasley twins come in talking about their latest product.

"How are we going to make them do whatever we want?"

"I don't know we need to make that spell that connects mind from the touch of the hand to the consumer."

"We've searched everywhere and so far we've only gotten the relationship that connects the sweet to the touch."

Jet strained her eyes to hear. She laughed. She could do that spell easily. She wanted to make such a sweet to give to the Ministry so that they didn't have to use the Imperius curse. Zonko, though, did not want such a sweet in case it fell into the wrong hands.

"Fred, find the spell!" George whined. Jet smiled.

"I can't George, you know that. I need to read so a couple more books I got from the library."

"We don't have time."

"What do you mean?"

"I want to go onto our next product." Fred laughed at his twin.

"All in good time my friend." Jet looked at them and couldn't resist.

"I know the spell." The twins looked around to see the person who spoke.

"Who are you?" Fred asked. George smacked him in the stomach.

"I'm George, this is Fred. Hi, who are you?" He then turned to his brother. "You have to be polite you git." Jet grinned.

"Pass me the sweet." Fred looked at her suspiciously.

"Who are you?" He asked again.

"My name's Jet Smith and I'm in the fifth year." George looked at her closely.

"Say, you look oddly familiar."

"You probably see me every day in the corridors but have never said a 'hi'." George looked at his shoes guiltily.

"Hang on, hang on. You're that girl who spends half her detentions with us." George looked up.

"Guilty." Jet grinned.

"Jeesh, how many detentions do you get?" Fred asked.

"Quite a bit. Filch gives me many detentions." Fred and George sat on the armchair and looked at her.

"What?" She said smiling at them a bit scared.

"Tell us more." George said. And Jet told them everything.
