Disclaimer: I don't own them, just borrowing them to play with my imagination. I promise they'll go back exactly the way I found them! Miya Miranda Malfoy is mine, and any new character that wasn't in the book!

A/N: I started a similar story called New Friends or New Enemies? Well I didn't like it so I'm rewriting it to Mistakes (this story). I hope you like this one. Please comment! I would love to hear from you! This story will revolve around several characters, but each couple of chapters will revolve around a particular person or two. Hope you enjoy!

Mistakes

The Hogwarts Express was on its way. The smoke cleared by the red engine. Harry sat with Ron and Hermione in one of the compartments. He was happy, excited, sad and miserable at the same time. He was glad to be going back to the place he called home, but Cedric's death still hung over him. He wasn't sure how people would react to him. He kept himself out of contact with most people on board, having gone straight into one of the compartments. He still blamed himself for Cedric's death, no matter how much others told him it wasn't his fault.

Ron and Hermione knew that Harry was still upset but tried to keep him cheerful. They all exchanged stories about the summer and ideas about what would happen that year.

"I wonder who'll be our Defense Against the Arts teacher will this year?" Hermione wondered. At mention of this Harry perked up.

"I almost forgot to tell you. Moony sent me an owl before we left. He's back! He'll be our new DADA teacher again!" Harry smiled.

Ron and Hermione smiled too.

"I wonder if he's on the train." Ron asked.

"Nah. He said he was already at Hogwarts. But he did say there was a surprise for us this year." Harry replied.

"Surprise? Like Tri-Wizard tournament surprise? Or some other kind of surprise?" Hermione asked.

"I don't know" Harry shrugged. "He just said a surprise."

They went through the rest of the ride speculating what it could be.

Harry, Ron and Hermione sat in the dining hall cheering for the newly sorted students. As the hat finished, Dumbledore stood up and welcomed everyone. As he was talking everyone noticed a woman come into the room.

"Ahh, reminds me." Dumbledore said thoughtfully as he gave her a nod of acknowledgement. "I was going to announce this later, but I'll do it now. As you know our DADA position was unfortunely empty at the end of last year."

"I thought you said Lupin was professor?" Ron whispered to Harry. Hermione motioned for him to be quiet.

"Well I'm happy to welcome back Professor Lupin." Applause went around the room, except for the Slytherins. "And his new teaching assistant, Professor Malfoy. She's a student teacher and will be training under Professor Lupin."

The room was silent except for the clapping coming from the Slytherins. Yet quickly others joined in. Everyone was shocked that a Malfoy was teaching but what was more surprising was how different she looked from Draco and his father. She was slender and pale, but she was clearly Asian and she did not have the same platinum blonde that Draco had. She was young, in her twenties and had jet-black hair. It was pulled back into a high ponytail clasped by two linking silver snakes. She had black robe on that was embroidered at the edges with similar looking silver snakes and stars. She smiled and waved at the students and took a seat between Lupin and Snape.

"I am sure you will all treat her with the same respect as your other Professors." Dumbledore said as the students quieted. "Now that we have done introductions lets eat!"

Quickly food appeared on the table and they began eating. Everyone started to talk about the new teacher and everyone was looking at Draco. It was quickly passed along that the new teacher was Draco's cousin. He was smiling broadly and proudly at the fact she was sitting up there. Harry caught Draco waving up there every now and then.

"Oh great!" Ron moaned.

"What?" Harry and Hermione asked.

"She's a Malfoy, which means she was a Slytherin. Which means we're doomed!" Ron complained.

Hermione replied, "It won't be that bad. Professor Lupin will be there teaching the class too. She can't be judgmental with him in the class. Anyway she doesn't seem that bad. Definitely not as bad as Snape!"

"I have to agree Ron. Look she and Prof Lupin look like they are getting along fine!"

All three looked up at the teachers. Prof. Malfoy was talking animatedly with Lupin and they were clearly enjoying the conversation. As Ron and Hermione turned their attention back to the table, Harry was still watching. Prof. Malfoy was getting one of the peppershakers, which Snape was also grabbing. Their hands had touched, which she drew back sharply. Harry saw a flicker of disgust in her eyes and as she slightly moved closer to Lupin. What surprised Harry more was the look in Snape's eyes. He thought he saw a flicker of sadness in his eyes, or was it regret? Before Harry could contemplate it more he saw Snape turn his eyes towards him. Snape's expression was back to his normal glare of contempt and sourness.

At the other table Malfoy had watched the same thing unfold. He wondered if his cousin being there was a good thing. He hoped it was not a beginning of a disaster. He turned to see where Snape was glaring and saw it was Harry. Harry then caught the eyes of Draco, the two stared coldly at each other, and questionly. Draco vowed to keep the secret of his cousin and Snape quiet.

Remus sat by the fire in his office smiling. He heard a knock at the door. "Come in."

"Hey Remus. I'm not disturbing you am I?"

"No, come on in Miya!" Remus replied.

"Why do you keep it so hot in here?" Miya asked as she took the robe off. She was about to sit in the chair when she noticed someone else was in there. "Snape!"

"Funny Snape said the same thing. Must be something about Slytherins." Remus said. "Hmm, yes we were discussing about the classes this year." Remus replied as he conjured up another chair. Miya stood unsure whether or not she should go or stay.

"Well I can go since you're busy- I"

"Stay Miya." Snape said quietly, then with added sarcasm. "You'll have to get use to my being around whether or not you like it."

"Hmph. I guess I will." She replied icily.

"What brings you here?" Remus asked trying to calm the two.

"I just wanted to talk about tomorrow's lesson." Miya said. She sat down and tried to get comfortable. Both men watched her in silence. She was wearing a dark velvet blue short-sleeved shirt that went down enough to entice a man to use his imagination about her bust yet be modest at the same time. She wore dark black pants to go with it that showed the nice shape of her legs. Remus smiled as he noticed Snape's lingering gaze on those legs.

"What about those lessons? I thought we went through it over a thousand times this summer?"

"Well you know me- I'm just nervous I guess." She said as she finally settled down and looked back at the two men. "And can't transform a more comfortable chair?"

Remus laughed. "I did transform it out of a box."

"Transfiguration was never his strong suit." Snape replied coldly.

"Nope never was. Anyway I think you should stop worrying, Miya. You'll be fine. Anyway I'm glad you came down because I wanted to talk to you about the dueling club and team."

"Perhaps I should leave now." Snape said as he started to gather up the folds of his robes. He was tired of either being ignored by Miya or getting ice-cold daggers from her eyes.

"You should stay." Remus replied. "I asked Sev to help coach as well, hope you don't mind Miya."

"Mind?!?" She said thin-lipped. "Why should I mind? He's just the bastard who-"

"Who what Miya?" Snape asked sharply. "I'm the bastard who what?"

"You know as well as I do. No need to say anything." Miya crossed her arms and stared at him coldly.

"Then why mention it?" Snape challenged. Before either could say anything Remus interrupted.

"Well I think that Snape will be a good addition. He's good at dueling and plus you know the headmaster thought we should have someone else to help out." Remus replied.

"Whatever you think is best Remus." Miya got up and grabbed her robe. "I will see you tomorrow."

She left the room with Snape looking coldly at her.

"You should go after her." Remus said as he looked at the standing Snape.

"No need- you heard her. She thinks I'm a bastard."

"You should explain it to her, Sev."

"I can't and you know it. You know its best she never knows the truth."

"She'll find out someday. Might be better to hear it from you."

"Remus- I think I know best how to handle this. After all I know how to deal with the Malfoy's better then you. I've been around them all my life."

"Sev, no offense or anything, but I think you're still wrong."

"What's new?" Snape snapped back at Lupin. Lupin sighed.

"Just trying to help that's all."

"I know Remus. I just don't think this situation can be helped. Night." Snape walked out of the room. As he was making his way back down to his dungeon he saw Miya looking out one of the balcony at the end of a hallway.

He stood behind one of the pillar doors and watched her. He saw that she had tears in her eyes and her hand was holding onto an end of a necklace. His heart broke at the sight and all he wanted to do was to hold her. He had stepped out to do just that when she turned sharply around.

"What do you want?" She asked coldly.

"I just wanted to see if you were alright." He replied softly. She laughed, it was a cold and sarcastic laugh.

"Oh I'm just fine and dandy." She hissed, anger radiating from her. At that moment she looked even scarier then Snape did on his bad days. "You don't have to worry about me. You gave up that right a long time ago. You made it loud and clear you didn't want me around!"

"Miya-" He tried to grab her arm, as she was moving past him.

"Don't! Don't you ever touch me again! Just stay away from me!"

"Fine! If that's what you want! I was just trying Miya. I thought you were old enough to try acting like an adult!" Snape dropped her arm angrily, his eyes going cold.

"That was the problem wasn't it? I was just too young for you! I was too much of a child! Yet that wasn't a problem when I was in your bed was it? Just when my family found out! You are such a bastard!" She said in a low and dangerous voice. With that she ran down the hall and up one of the corridors. Snape just watched her go, his feelings mixed, but mostly he hated himself.

"I'm sorry I hurt you." He said softly to himself as he looked back out the balcony and realizing for the first time where he was. "I'm so sorry, Miya."
