A/N: Fourth Chapter. Wow, this is getting long. I'm up to chapter 12 and it still isn't even near the end. Read and review, please!

'You still have your wand, I presume?' Dumbledore asked the Doctor.

'Yup,' he said, drawing it from his pocket. Bree looked worried.

'Um, I don't have one of those things, is that a problem?' she asked Dumbledore, unsure how to address him.

'Fawkes will make you one,' he said, and gestured to Fawkes, who disappeared in a flash of flames. 'You also need to be sorted into a house. There are four houses in this school, Hufflepuff, Gryffindor, Ravenclaw, and Slytherin. Each are special and unique in their own way,' Ron snorted, but Dumbledore ignored him, 'and you are put into them, depending on your personality, or traits.' He passed Bree the sorting hat. She looked at it, confused.

'Put it on,' said Ginny, helpfully. Bree gingerly put it on her head, because it looked like it was about to fall apart.

Hello, you must be new.

Bree jumped.

Are you the hat?

Yes.

So you decide which house I'm in?

Yes, that is correct.

Can I go in the one the others are in? So I know someone?

Gryffindor? Well, you would fit in that house, however you are almost too clever, maybe Ravenclaw… but yes, I suppose Gryffindor would be best. GRYFFINDOR!

The hat shouted the last word to the rest of the office, and Bree removed the hat. The others were smiling at her.

'That's great!' smiled Ginny.

'I knew she was a Gryffindor,' said Harry, also smiling.

'HAH! Take that, Slytherin!' said Ron triumphantly, punching the air.

Dumbledore smiled and Fawkes arrived with another flash of flames. He dropped a thin stick of wood on his desk.

'Ah. Oak, 14 inches, with a… an unidentifiable core. This is your wand. Doctor, what subject would you like to teach?'

'Would a muggle subject be OK? I'm most comfortable with Science.'

'Yes, that would be great, 'cause then I'll know something,' said Bree, 'I love science, 'specially physics.' Ron looked confused, and Harry looked worried.

'You do? Great!' said the Doctor.

'As for books and clothes for Bree and textbooks for you, Doctor, I'm sure the room of Requirement will provide the necessary things. You can have classroom D, which has an office and lodgings. Bree, an extra bed will be added in the girls dormitory.'

'Hang on a minute. I still don't get why I have to stay here. Can't I just go home another way?' She asked, confused. Dumbledore ignored her and pressed on.

'How old are you?' asked Dumbledore.

'Well, my birthday's the 25th of April, and I'm 16. It's November, yes?'

'Yes.'

'So I'll be 17 next year, in 2012.'

They all gasped.

'Ah,' said the Doctor, looking guilty.

'What?'

'Bree, it's 2008.'

'Oh.'

'Yes, sorry about that,' the Doctor said, running his hand through his hair. She thought about this in silence for a moment.

'So, I guess I'm stuck here until you get the TARDIS fixed, then.'

'So, Bree, you'll be in sixth year, with Harry, Hermione, and Ron. Harry, could you take them to the Room of Requirement?'

'Yes sir,' he said, and led them out the office. 'The Room of Requirement gives you what ever you need. We used it for a secret club last year.'

'It's so great you're in our year!' said Hermione.

'At least I'll know some people. Is this magic lark hard?' she asked, twirling her wand between her fingers.

'You might struggle a bit, going straight into NEWT courses…'

'What…'

'Like A levels,' said the Doctor. Bree nodded in understanding.

'But we'll all help you.'

'Are you in their year?' Bree asked Ginny.

'No, but I'm only the year below them,' Ginny replied. Bree was glad. She liked Ginny, and could see an interesting relationship between her and Harry.

'I think Harry fancies you,' she whispered to Ginny, quietly. Hermione also leant in.

'I told you, Ginny. Bree's only been here a few hours and she's noticed.'

'No, he doesn't. Anyway, I'm with Dean, now.' Bree and Hermione giggled. Ginny ignored them.

'What's going on back here, then?' asked the Doctor, They all broke out into uncontrollable laughter. The boys looked worriedly at them, before continuing. Collecting themselves, the girls followed them.

'Here we go,' said Harry, as they stopped in front of a blank wall.

'Err…' said Bree, but she went quiet when a door appeared. Inside the room were two trunks, a normal sized one for Bree, and a larger one for the doctor. Hermione showed them both how to cast locomotor charms, and the trunks followed them to the Gryffindor Common Room. Harry showed the Doctor to his classroom, and they all flopped down on the chairs in front of the fire.

'God, I'm tired,' said Bree. 'It was night time when I hid in the TARDIS, and now its morning. I've got a whole day to go before I can sleep.'

'You go and sleep, it's Saturday tomorrow, and there's no point in you starting lessons now. The Doctor probably won't start until Monday, when Dumbledore's sorted out the Timetables.'

Bree yawned and trudged up the steps, her trunk following her.

'It's the one with Sixth year on it!' Hermione called after her. 'We should go to lessons now,' said Hermione. They all groaned.

****

The Doctor had organised some of his lessons, and had had a flick through the textbooks from the Room of Requirement. They were good. He decided to go and see the TARDIS.

'Hello. I'm sorry about this,' he said, stroking the side, before going in. He got some weird stares from passing students, but he ignored them.

The TARDIS was in bad shape.

'I'm so sorry,' he crooned, patting the dashboard. He started to look at the damage, and realised he would need help. Someone as clever as him would be best, and he had an idea. He bounded off to Dumbledore's office.

'Can a friend of mine come to this school, to help me fix the TARDIS?' he asked.

'How old is this friend?' asked Dumbledore.

'Technically, he's quite young, but he's about 16, I think.'

'We have a space in Harry's year, there are only 5 boys. It's a very small year. Your friend can come; you can have whatever you need to fix the TARDIS.'

'Thanks. I'll just floo over to his house.' The Doctor took a pinch of the powder from a pot near Dumbledore's fireplace. He stood in the fire and let go of the powder.

'15 Bannerman Road!' He shouted, and he was gone in a rush of green flames.

He shot out of the fireplace at the other end, much to the surprise of the 16 year old boy, who had been reading by the fireplace.

'Doctor?'

'Hello Luke.'

'Mum's out, but she'll be back by lunchtime…'

'Good, but it's not Sarah Jane I need. It's you.'

*****

Sunday morning dawned bright and clear. Bree, having slept through the rest of Friday, woke feeling rather lethargic on Saturday, like you always do after sleeping for too long, so she didn't do much except flick through her new books. It was all very interesting. She had also spent some time with the Doctor, before making her way back to the common room, and going to bed early.

Bree had met the other girls in her dormitory, and they were nice, but she got on best with Hermione and Ginny, who sometimes ate with her in the kitchens. This morning, however, Hermione was still asleep, and knowing Ginny wouldn't want to be disturbed, she decided to go on her own.

She stretched, and drew her curtains.

Today Harry and Ron were going to teach her to fly. They'd promised her the other night, when she woke up, hungry. This was what she had looked forward to the most about the magical world, although spells were cool. Not feeling homesick at all, she got dressed into some jeans and a T-Shirt she'd found in the trunk from the Room of Requirement. It all fit better than her clothes at home.

Dumbledore had requested that she not make a public appearance until Monday, so she made her way down to the kitchens, where the Doctor would also be. She liked the Doctor. Although she'd only just met him, she felt like she'd known him for years.

This morning, he was reading the paper. She was amazed to see that the pictures of the Daily Prophet were moving, but she was used to the magical world now, and didn't trouble herself thinking about it too much.

'Anything interesting?' she asked, companiably.

'Not really.'

She scoffed her breakfast, anxious to fly.

'You look excited. What are you doing today?'

'Harry and Ron are teaching me to fly on a broomstick. I can't wait!'

'Oh yeah, Minerva wants to see you in her office at ten o'clock.' Bree looked anxiously at her watch, and then remembered it had broken the night she was chased. She suspected it was when she fell over.

'Don't worry, it's only 9. Here, you can borrow mine.'

'Thanks.'

As she lent forward to take his watch, her necklace dangled over the table. She'd always worn it, but she never knew why she was so attached to it. The Doctor looked startled, but his expression changed abruptly back to impassiveness. He smiled at her.

'Are you going to help me fix the TARDIS?'

'I might as well, considering it's my ride home. Of course!' she grinned. 'Though I would much prefer to stay here.'

'You can choose when it's ready. Dumbledore's going to move it to Hogsmeade…'

'What's Hogsmeade?'

'A little village just outside Hogwarts grounds,' said the Doctor. 'He's going to move it today, so we can start on repairs. I don't know how long it will take to charge up though.'

'Ah well,' said Bree, and they ate in silence for a while. Bree produced a book and read it while the Doctor read the paper.

'Oh no, it's nearly quarter to ten!' gasped Bree. 'I completely lost track of time, and I need at least half an hour to get there, in case I get lost.' She rushed out the kitchen, waving a hasty goodbye to the Doctor. He smiled, rolled up his paper, and followed her out.

Bree burst through the door of McGonagall's office, only two minutes late. On her way, she'd managed to knock at least five people to the floor, and tripped a million times. She wasn't the most graceful person on a good day, and definitely not under pressure.

'Sorry I'm late, I got lost,' she gasped. She was just glad she didn't have her bag of books. She would definitely be out of breath then.

'Don't worry, Bree, we're still waiting for the Doctor.' She gestured to herself, and to a boy lounging on a desk in front of her.

'Hello,' he said. She gaped. He was wearing normal clothes, like she was, but he obviously didn't go to Hogwarts. He didn't have a wand sticking out of his back pocket of his trousers, like everyone else did, but was examining one in his hand. Bree didn't like this school habit, as it was very uncomfortable, and so she put her wand in her hair. It kept it out the way, and stopped her hair getting in the way. Two birds with one stone.

'Um, hi,' she mumbled. She felt very stupid. Not to mention she was panting heavily and slightly red-faced.

'This is Luke Smith, a new student like you,' said Professor McGonagall. Then the Doctor burst in.

'Luke! Glad you could make it. How's your mum?'

'Fine. She let me come eventually, but I had to milk the whole situation about you and another poor soul being stuck here without my help,' he said grinning.

'Are you here to help fix the TARDIS?' asked Bree, looking him up and down. He looked about her age, and he had light brown hair and blue eyes. His eyes were very innocent looking, and so was he. He looked questioningly at her, and she realized she'd been staring.

'What house are you in?' she asked casually. He was quite fit, actually. Please be in Gryffindor, please be in Gryffindor…

'Well the hat wanted to put me in Ravenclaw,' he shared a grin with the doctor, 'but it decided that while I am clever with some things, I'm not so good with others.' Again he shared a knowing look with the Doctor. Bree was beginning to get frustrated. 'So the hat put me in Gryffindor.'

'I'm in Gryffindor, too,' she said, trying not to sound too happy about this.

'Your stuff will be put in your dormitory, so you are free to do whatever you like for the rest of the day,' said Professor McGonagall. 'You both shall be introduced formally to the school tomorrow morning at breakfast.' They both nodded, and the Doctor sauntered out.

'I have to meet Harry, Ron and Hermione down by the Quidditch pitch in a few minutes,' said Bree, glancing at her, or technically the Doctor's, watch, 'Do you want to come too? You're in sixth year too, so you could meet them.'

'Yeah, sure,' he said, and followed her out the classroom. 'You still haven't told me your name.'

'It's Bree,' she said, shy all of a sudden.

'Unusual name,' he commented.

'My parents were unusual,' she murmured.

'So were mine,' he laughed, 'honestly, you have no idea how weird mine are. So, how did you get stuck here?'

'I was being chased, and I hid in the TARDIS. It was foggy, so I didn't see what it was, and I passed out almost as soon as I'd sat down,' she said. He looked shocked.

'When did this happen?' he asked.

'On Friday.' They walked in silence for a while, and Bree managed to remember the way to the Quidditch Pitch, without getting lost more than twice. When they arrived Harry and Ron were already in the air, while Hermione hovered by the school broom they'd brought out.

'Oh good, you're here. I thought you'd got lost. Who are you?' she asked, surprised at seeing Luke walking next to Bree. Harry and Ron flew over.

'Guys, this is Luke Smith. He's going to help the Doctor and me…'

'Doctor and I,' corrected Hermione.

'Fix the TARDIS. He's in Gryffindor, our year,' she said. 'Luke, this is Harry, Ron, and Hermione.'

'Do you want to fly too?' asked Ron. Luke nodded, looking excited.

'I'll just go and get a broom for you,' said Hermione, and she rushed off to the Broom shed. Ron handed Bree the other one.

'You hold it like this,' he demonstrated, 'and you get on it like this.'

'OK,' she said, uncertainly, as Hermione came back with another broom. Luke copied the hand grip and mounted his, grinning.

'As long as it's easier than football, I don't mind,' he said.

'And you push off like this,' said Harry, and he shot off up into the air. Bree gave it a go, and found it to be relatively easy. She whooped, and pushed the broom on faster. She and Luke had a race to the goalposts, and then Harry got out a tennis ball. They played catch, with Hermione levitating the ball back to them whenever someone dropped it (which was quite often, and mainly Bree and Luke). Soon their faces were red with cold, and flushed with exertion. They stopped only when Ron's stomach rumbled so loudly Hermione heard it from the ground and told them to come down for lunch.

Bree was happier than she had been in years. She had friends, a comfortable place to live, and the promise of many exciting lessons. Also there was no Aunt Malice to interrupt this happiness, as she always managed to get in the way before.

She thought she was starting to get a little crush on Luke, as she had dropped the tennis ball many times because she'd been watching him. At least it's him, she thought, as Harry is already taken, and Ron was apparently going out with Lavender, a girl in her dormitory, at whose mention Hermione became very quiet and snappy. Somebody's jealous, she thought.

A/N: Oooh, Hermione's jealous. So, tell me what you thought. Review people!!
