A/N: Sorry for the wait but here's the next chapter! It still ties in with the episodes but this is where I'm starting to put my own plot in at the same time!

Once again, thanks for all the reviews, favourites and follows!

As usual, reviews would be appreciated.

The Doctor stood, staring up at the block of flats that Rose lived in. He had to admit the building was rather large, he just hoped he wouldn't get lost when he entered it. He pulled a crumpled white piece of paper out of his pocket and unfolded it to look at the writing on it. He looked at his scribbled writing in amazement. When he had been talking to Rose on the phone and had quickly jotted down the number of her apartment, he hadn't realised how messy his handwriting had been. He was just glad he could read it still!

He could just make out the numbers he had scribbled down so set off, into the building and up the first flight of stairs he came across. Finding Rose's apartment wasn't as hard as he first imagined, and he soon found himself knocking on the door.

After thirty seconds, Rose opened the door. "You're early," she pointed out, glancing over her shoulder into the flat with a worried look.

"I am?" The Doctor asked in shock, having not realised the fact. He looked at his watch which only confirmed what Rose had just told him. "I'm sorry. Don't worry about me, I'll just wait here." He turned to look at the view over the balcony but was pulled into the apartment by Rose grabbing his bag strap.

"I shouldn't be too long. I just need to get my lunch sorted," She told him, letting go of his bag strap and kicking the door shut. She poked her head into the first room on the right. "Mum, the boy I was telling you about is just in the hall."

"Oh, the Doctor?" A voice from inside the room spoke.

"Yep," Rose nodded then returned fully into the hallway where the Doctor was frowning at her.

"You introduced me as 'the Doctor'?" He hissed in surprise.

"Look, I don't know! It just sort of slipped out when she asked!" Rose replied, amused by the surprised look on his face. He opened his mouth to reply but she had already disappeared into the kitchen.

"She talks about you a lot, you know," The Doctor glanced to his right in surprise when he heard a voice. A middle aged lady with blonde hair was stood in the doorway Rose had previously popped her head into.

"Oh, hello Mrs Tyler," The Doctor greeted her, finding that more comfortable than trying to think up a good reply to what she had just told him.

"I suppose you get that a lot," Mrs Tyler continued.

"I'm sorry?" The Doctor frowned in confusion.

"I bet you get a lot of girls talking about you," Mrs Tyler repeated in simpler terms.

"Erm, I'm eleven, Mrs Tyler," The Doctor said, feeling awkward now. He glanced towards the kitchen, wondering how much longer Rose would take.

"Even six year old have crushes nowadays," Mrs Tyler shrugged.

"Mrs Tyler, I don't know what you think is going on here but I can assure you, Rose and I, we're just friends," The Doctor spoke at a fast pace, trying to get the situation clear for her as quickly as possible before the conversation could get even weirder.

"For now," Mrs Tyler added on to his explanation.

The Doctor opened his mouth to speak, but couldn't think of anything to say. He closed his mouth and glanced around before speaking again. "Could I use your bathroom?"

Rose had taken a lot longer than she had hoped to in the kitchen. She felt bad for leaving the Doctor alone in the hallway but hadn't expected to take so long. She always found that, much to her annoyance, whenever she was rushing, her fingers would just stop working, resulting into her dropping things all over the floor.

She was surprised to find an empty hallway when she returned to the spot she had left the Doctor. She sidestepped to her left, into her mum's room once again, who was busy doing her hair. "Where's he gone?" Rose asked.

"He wanted to use the bathroom," she replied, not looking around.

Rose returned to the hallway to wait for the Doctor, wondering how his and her mum's conversation went and if that conversation was what led him to retreat to the bathroom.

When the Doctor emerged from the bathroom, he was glad to see that Rose was now ready to go. She opened the front door so he walked through it and waited, looking at the view below, as she locked up.

After she'd locked up, they set off towards the school, chatting as they walked.

It wasn't long until they reached the school gates and the Doctor froze when they walked past the school car park, frowning at the cars. "Come on, Doctor!" Rose ran back to him when she realised he had fell behind. "We're going to be late to first lesson!"

"But Rose!" The Doctor complained when she tried to pull him along. "Haven't you seen the staff car park?"

"Yes, it looks dull as usual," Rose spoke, barely glancing over at it. "Now can we get going, please? We have English first! I'm sure you look forward to arguing with Charles!"

"No! The cars aren't the same ones as usual!" The Doctor pointed out, still refusing to move.

"Maybe there was a deal for new cars this weekend," Rose concluded with a shrug. She didn't really care about what kind of cars the teachers owned.

"Two thirds of the teachers would not have changed their car in two days," The Doctor argued, his eyes still fixed on the staff car park.

"Clever kid," A voice sounded from behind the pair, making both Rose and the Doctor jump and spin around to see who was speaking. The man in question was rather tall and quite plump, wearing a suit. "You're… John Smith, am I right?"

"How do you know my name?" The Doctor questioned, unable to rid the feeling that the man in front of them was acting suspiciously. The way he composed himself seemed suspicious, the fact he knew his name seemed suspicious and the way he was talking seemed suspicious.

"I take pride in learning as many names as possible when I fill in as headteacher for a school," the man replied.

"What do you mean, fill in?" The Doctor inquired, questions filling his head. "What's happened to Mr Mott?"

"Oh, you're full of questions aren't you?" Came the initial reply. There was a moment of silence before the Doctor received some answers. "Unfortunately, many of your teachers have come down with that horrible flu going around. My company fill in for teachers. That's why many of the cars are different. Now then, does that answer all your questions, young man?"

The Doctor opened his mouth to reply when a woman he didn't know appeared beside the man. "Ah, John Smith and Rose Tyler!" The Doctor wasn't as surprised this time when he discovered that this woman also knew their names. "You two are meant to be in my English class. I'm filling in for Miss Smith!"

For some reason, the Doctor felt like he could trust this woman a lot more than he could trust the man so moved to her side with Rose. "Hold on a minute!" The man objected as the three began to walk away. "Who are you?" His question was designated for the woman standing in for Miss Smith.

"I'm Miss Jones, one of the school's usual supply teachers," She replied. The Doctor frowned; he thought he had met all of the school's supply teachers. "Now then, Mr Green, can I return to my English lesson?"

"Of course!" Mr Green responded with a nod though, for a reason the Doctor couldn't work out, he was staring straight at the Doctor.

Miss Jones began to lead Rose and the Doctor to their English room. "Miss Jones, I don't want to be rude or anything, but I'm pretty sure you're not a usual school supply teacher," the Doctor spoke up when they were out of Mr Green's earshot.

"Ah! You're as clever as they say you are!" Miss Jones grinned, glancing at him. The Doctor glanced at Rose, who also looked confused.

"As who? The teachers?" Rose questioned when the Doctor didn't ask.

"Of course not, Rose!" Miss Jones responded, with a little laugh. "John knows who I'm talking about."

"I really don't," The Doctor replied, shaking his head.

"Maybe I should start with the basics," Miss Jones said, almost to herself, before suddenly stopping in the middle of the corridor. "I'm Harriet Jones, leader of the Bad Wolf division within MI6."

"MI6?" The Doctor and Rose exclaimed at the same time, their eyes widening. What where MI6 doing in their school.

"Oh, goodness. You really don't know, do you?" Miss Jones made a worried looking face before hurrying into their English classroom.

"What are MI6 doing in our school?" Rose asked the Doctor, having to splutter out the words as she overcame the shock.

"Your guess is as good as mine," The Doctor shrugged before strolling into the classroom, as if nothing had just happened but many things were bugging him. Why did Miss Jones expect him to know what she was talking about? What was the Bad Wolf division? What was MI6 doing in his school? In fact, what on Earth was going on?
