Chapter 1 – Smith & Lewis.

Katy smiled as she walked through the crowd of college students trying to get to their next class. It was a beautiful summer's day and Katy couldn't be any happier. Her curled brunette hair whipped behind her as she walked. Her eyes, a dark brown that anyone could get lost in and perfect completion. Katy smiled to fellow students and said a friendly 'Hello' as she made her way to class.

Her next class was A – Level physics, which she was hoping to drop after her first year of college. Katy thought that the science of how the world works and how it evolved would be gripping and exciting, but unfortunately Katy was fed up with it on day 1.

Just before she turned the corner to the science department she collided with some object. She fell back onto the floor and looked up to see a tall man standing around 6"1 wearing a brown pin stripe suit and a pair of pale, worn out converse. The man held out his hand which Katy took gratefully. She brushed herself off and looked up at the man again to see his face. The man had brown, messy hair along with a pair of chocolate brown eyes which came across as old. Katy stood back slightly. He looked really familiar, like they had met before. But the man flashed a cheeky grin making Katy blush.

"Sorry about that, I'm looking for my class," The man finally spoke.

"You're a teacher here?" Katy asked rather shocked, he didn't seem anything like a teacher.

"Yes, you don't think you could direct me could you?" The man passed her his timetable which Katy studied, she then smiled.

"You're teaching me next, you can follow me," The man smiled and Katy passed back the timetable. They began walking to lesson in silence until the new teacher spoke.

"So what's your name?"

"Oh, Katy Sir, Katy Lewis." She replied looking at her new teacher. He was quite handsome.

"Nice to meet you Katy, I'm John, John Smith," They shook hands and Katy noticed how eccentric he was.

"So is it your first day Sir?" Katy asked.

"Oh don't call me Sir, Just John,"

"Okay, John," Katy said nodding almost checking to see she was right.

"Yeah it is my first day," They continued walking in silence until they were outside the class. They stop and neither opened the door. Katy turned to John smith.

"John Smith, is that your real name?" John Smith was taken aback but answered.

"What makes you say that?"

"You don't seem like a John Smith you seem….."

"Seem like what?" John asked.

"I'm not sure, It's probably me being silly," She thought back to were she had seen him before. What was his name? More to the point were had she seen him before? John nodded and grabbed the handle of the door.

"Here I go!" Katy laughed and entered the classroom and sat in her seat. John introduced himself and Katy seemed to be more and more interested into her Physics.

*****

During the lesson The Doctor looked at Katy, the young girl who he bumped into. She was paying the most attention in her class compared to the others. I have that affect The Doctor thought. Katy was different to other girls he had come across. Even Martha Jones, A Doctor, didn't even question the lord of time on whether his name really was John Smith or not. He hated lying to people but it was a risk he was willing to take. The lesson went smoothly, no paper airplanes flying about! The reason The Doctor was on earth again was because he got a signal in the London area from a college. Well nothing strange yet.

After the lesson, The Doctor debated on whether to speak to Katy again. If he did then she might get wrapped up in his disasters and either end up following his around the universe or end up dead because of him. Was he willing to risk it?

"Katy?"
