"Ready," Rose said running back over with two bags full of clothes and a note in her hand. Then she took the piece of paper and handed it to Dumbledore.

"Might I enquire what this is Rose?" Albus asked her with a small smile pulling at his lips,

"It is written permission from my mother sir," Rose said "for me to be able to go with Harry for the foreseeable future even when he goes to his magic school I can come with him."

Harry froze at this, he knew that muggles couldn't see Hogwarts, there were charms that sent muggles away from the school but he knew that he didn't want to lose Rose and he would gladly stay out of the school to keep her safe.

"Erm Rose," Harry said and then gulped "there is a slight problem with that, none magical people cannot see Hogwarts at all,"

"So I cannot be with you?" Rose asked with her eyes filling with tears and worry.

"There is one way," Albus said "that is to say, a way that you could possibly come to Hogwarts if your mother and Mr Potter approve of it."

"What is it?" Rose asked eagerly.

"There used to be a position at Hogwarts," Albus said "to do with the muggle studies teacher where we allowed muggles to be assistants to the teachers, it hasn't occurred since I myself was a student, it was ended to protect the muggles that came to the school, especially after the chamber of secrets opened the last time Harry."

"Is it safe?" Harry asked "for her? I mean no one in Voldemort' forces are the defence teacher are they?"

"I am confident that he isn't a follower of the dark lord Harry," Albus said with a grin "I have known this young man since he was a young child,"

Harry nodded at this and Albus and Harry both looked at Rose.

"So Rosie?" Harry asked her "do you want to come and be a teacher?"

Rose pretended to be thinking about it but beneath the surface she was brimming with excitement at the thought of being with Harry for the full year even though she would just be helping some teacher but at least it would mean that she was with Harry which was what she wanted and she didn't care that she had to be a teacher do it.

"Ok," Rose said eagerly "what do you need me to do?"

"It would be simply adding and correcting the teacher when needs be," Albus said almost dismissively "something I feel that you wouldn't have any problem doing Rose,"

Rose blushed at this but nodded and smiled.

"Right," Albus said "if we are ready, I need both of you to read this," Albus then handed them a small piece of paper.

'The Order of the Phoenix is located at 12 Grimauld place.'

"What is Grimauld place sir?" Harry asked

"I will explain when we get there Harry," Albus said and then extended a hand to Harry for him to take and Rose to Harry' other hand and the three apparated away.

They arrived in the upstairs of a house almost silently with only a slight pop in the house.

"This the ancient and most noble house of Black," Albus said "a house of an all but dead dark family, Harry you yourself descend from the Black' on your great grandmother, you also know the only living member of the Black family that unlike the rest of his family doesn't prescribe to the pureblood agenda."

"Sirius," Harry breathed and Albus nodded

"He is here," Albus said "you can speak with him later he is currently leading an order meeting in my place whilst I help you get settled."

Harry nodded but Rose looked confused,

"Sirius?" she said "your godfather?"

"How much has Harry told you of our world Rose?" Albus said with an amused look on his face.

"Nothing," Rose said with a blush "a couple of times when we has fallen asleep together he has called out for Sirius and I asked him who he was so he told me he was his godfather,"

"Sirius is his father' best friend save Remus Lupin," Albus said " James Potter, Remus Lupin and Sirius Black had been best friends all through Hogwarts with another Peter Pettigrew, Peter Pettigrew betrayed the Potter's to the man that killed Lily and James Potter in 1981, I will allow Sirius to talk to you more about himself when you meet him."

"Ok," Rose said

"Now to the sleeping arrangements," Albus said "sadly there is not much room in this house with the order using this house as a base of operations and there are not as many rooms as we would like but there are a few options, Rose you could have your own room, or share with one of the girls that is the same school age as Harry if you so wish or a female order member however if you like none of those options I can offer another."

"What is the other option?" Rose asked

"That you sleep in the same room as Harry," Albus said and both teens looked at each other and where unsure if it was a trap or not, "I assure you I am being serious, the two of you are young adults, Harry turns 15 in 3 days and you Rose are 16 it is not like you are dating, I believe you are only friends and if you so wish I could put a dividing curtain in place whilst you change? I could also put in another entrance that connects to the shower that can only be used by the two of you?"

"If Harry agrees to that I will," Rose said confidently even though she was worried that Harry would reject her and not want to share a room with her.

"Ok." Harry said

"Now," Albus said "I will go and inform the order that you are here, I dare say that your friends will be waiting for you in Mr Weasley' room Harry." Then he turned and left, Harry knew that he should have been hurt that the Weasley's where already here and that he didn't get to have any time alone to spend with Rose and Sirius but he didn't want to seem childish after all they were all on the same side.

"So this is Ron and Hermione yeah?" Rose asked

"Yes," Harry said with a nod "now Ron tends to speak and then think sometimes so if he offends you please give him a second chance I don't think he has met a none magical person before."

"Ok but if he makes a blonde joke or something I am kicking his ass."

"Ok," Harry said with a smile "you know if you want me to change your hair colour all you have to do is ask Rosie,"

"Leave it like this for now," Rose said like Harry knew that she would, even though she claimed she hated being blonde because of the blonde stereotype she secretly loved that her blonde hair made her look even more beautiful or that was what Harry thought at least anyway as Rose was a really beautiful young woman and Harry did have feelings for her but he didn't want to ruin the friendship that he had with her.

Harry opened the door and walked up the stairs as he could hear the voice of Hermione Granger talking to Ginny Weasley about something.

"I think the owl year will be interesting Ginny," he heard Hermione say "especially as this year 5th year can be prefects I hope I get it,"

"You are a dead cert Mione," Ginny said "I mean no one is more academic or smart as you in your year,"

"Thanks Gin." Hermione said with a smile "so what about you? Are you looking forward to your fourth year?"

"Yeah," Ginny said "plus I think I might try out for the quidditch team, I mean Angelina, Alicia and Katie are in their last 2 years at Hogwarts one of them might not want to be a quidditch player anymore and might want to rely on their education more,"

"What could be more important than quidditch?" Ron asked dumbly

"Their education Ronald, they do need jobs after all" Hermione said which made Harry laugh as that he and Rose still hadn't been seen from by the doorway.

"Quidditch is a job." Ron said defensively "loads of people have jobs as quidditch players even Vickie is a quidditch player you don't criticize him"

Harry could see that Hermione was getting ready to erupt like a Icelandic volcano and decided to intervene for his friend.

"Ron you should really learn to keep your mouth shut." Harry said with a grin.

"HARRY!" Hermione shouted and launched herself at her best friend and pulled him into a tight hug "when did you get here?"

"Just," Harry said with a grin and then turned to Rose, "this is my best friend Rose,"

"Oh," Hermione said surprised and stuck her hand out to her "I am Hermione Granger I have known Harry since his first day at Hogwarts."

"That's nice," Rose said shaking the hand "I have spent every summer with him until he left for the past three years and now I am going to Hogwarts with you to help the muggle studies teacher."

"Why?" Ron said rudely cutting across them "what do they need you for?"

Rose was stunned by Ron' rudeness but Harry quickly came to her defence.

"Because Dumbledore asked her," Harry said darkly "and she said yes so that is all that there is to it isn't there Ron?"

Ron looked like he wanted to argue more with Harry over it but when he saw the protective fire in Harry' eyes when Ron had verbally attacked Rose he decided that he didn't want to piss off the boy who lived.

"So Rose," Ginny said bringing everyone back to the conversation "did professor Dumbledore tell you what you would be doing? I mean why would you not be at Hogwarts already as a student?"

"I am not magical," Rose said like it was simple "I believed your headmaster called that being a muggle, whatever that means but I will be helping answer questions about the muggle world and correcting the teacher where it is needed."

"So your muggle?" Ron said "will you even be able to see Hogwarts?"

"What is the matter with you?" Harry said turning to Ron "I mean could you be anymore rude?"

"Harry," Rose said reaching to get his attention "it's ok."

"No it isn't," Harry said his eyes not leaving Ron "what is the matter with you?"

"Her," Ron said nodding at Rose "how is she your best mate, I have known you longer, I have been with you the longest, in second year Hermione was the one that was petrified,"

"Not by choice Ronald," Hermione snapped back "I was attacked last year you acted like a spoilt child and you were the one Ron Weasley that abandoned Harry in that godforsaken triwizard tournament not me,"

Harry was surprised at the fire that Hermione' argument had, herself and Ron had argued before but Harry hadn't seen her put as much force into an argument as she had then in quite a while, the only other times Harry could think of where the situations involving crookshanks and Scabbers.

"Anyway," Ron said ignoring Hermione "where are your clothes mate I left you some room in the closet."

"I am getting my own room." Harry said

"Of course you are." Ron said darkly

"He is sharing though." Rose said "just not with you."

"Unlucky you mate," Ron said laughing "who is it? Snape? Moody I heard he snores really bad,"

"He is sharing with me," Rose said stopping Ron' monologue.

"WHAT!" both Weasley children shouted
