Chapter Two.

The Doctor watched Tilly carefully while he set the TARDIS coordinates. She was staring around her in awe, absolutely fascinated.

"It's dimensionally transcendental," she murmured and the Doctor looked up.

"How'd you know that?" he asked. Tilly stared at him.

"'Cause it's bigger on the inside," she answered. "I saw a thing like this on some movie once."

"Of course," the Doctor muttered as he pressed a button and flicked a lever. "Hold on."

The TARDIS began her dematerialization fairly smoothly, shivering slightly. Moments later they landed.

"Are we here?" Tilly asked excitedly. The Doctor nodded.

"But don't go anywhere yet," he warned as Tilly headed for the door. "There's a few things you need to know first. You cannot, I repeat, CANNOT do anything to interfere with the course of history. Also, you must be really careful. Anything could happen, especially around me. I seem to attract trouble."

"I bet you do," said Tilly with a wink and the Doctor wondered what she meant. "Can we go now?"

"I suppose so," the Doctor sighed. This girl was going to be a handful.

"So tell me about the things you've learnt from these movies," the Doctor asked as he followed her outside into a fairly empty London street.

"Oh, this and that," Tilly answered casually, looking around her in interest. "Where's Freddie Mercury? And is he with the rest of the band?"

"There'll be a concert tonight," the Doctor answered. "If I'm not human, don't you want to know what I am?"

"Are you evil?" asked Tilly, turning to stare at him accusingly. "Are you a bloodthirsty alien in disguise, here to kill us and take over Earth?"

"No!" the Doctor cried, shocked that she'd suggested such a thing. "I try my best to protect the Earth actually."

"What, by going to old concerts to watch bands perform?" Tilly smirked. "You look human enough to me."

Stopping outside a shop, the Doctor glanced at the date on that day's paper.

"Damn," the Doctor muttered. "I got the wrong date, concert's not til tomorrow night."

"Typical," Tilly laughed. "I take off with a psycho who thinks he's not human and he can't even get the date right to take me out to a concert."

"Hey, I'm not taking you out!" the Doctor said. "I'm taking me out, you just tagged along like a lost puppy."

"Can we get a coffee?" Tilly asked, ignoring his comment. "It's cold and I'm thirsty."

Tilly pulled on her puffy white jacket and looked considerably warmer as she followed the Doctor into a nearby cafe. She plopped down onto a seat at the little table furthest from the door.

"I hate being near doors," she explained. "There's always a cold draft. I'll have a latte thanks."

The Doctor realised she was staring at him expectantly and obviously wanted him to order. He considered protesting but shrugged before heading over to the counter to order their drinks.

"Thanks," Tilly said once the Doctor arrived back at the table. "Is that tea you're having?"

"Yes," answered the Doctor as he sat himself down and took a sip. "I have a thing for tea."

"How boring. Coffee is way better, nicer taste."

"I beg to differ."

They chatted for a while and the Doctor was beginning to think Tilly wasn't as bad as he'd first thought.

"So, if you're not human, what are you?" she asked.

"Ah, I was starting to think you were alright, then you go and get nosy on me."

"You were itching to tell me before," she pointed out.

"Yeah, I guess," the Doctor answered grumpily. "But now isn't the time. I'll tell you one day."

"You make it sound like I'm gonna stay with you after this," Tilly said.

"Well, if you want to stay then I suppose you can. Doesn't matter."

"Gee, I'm glad you sound so enthusiastic," she said with a roll of her hazel-green eyes.

The Doctor laughed and they sat at the table in amicable silence, lost in their own thoughts.

"We'd better get back to the TARDIS," the Doctor said after they'd drained their third cup of coffee and tea.

"The what?" asked Tilly looking up.

"My time machine space ship thing," the Doctor said. "My home."

"Why's it called the TARDIS? And why does it look like a police box?"

"TARDIS stands for Time And Relative Dimension In Space and it looks like that because the Chameleon Circuit got stuck back in the fifties."

"Fairo, let's go then."

They stood up and wandered slowly back to the TARDIS, rain drizzling half-heartedly from the cloudy grey sky. As Tilly stepped through the doors in front of the Doctor, she staggered slightly.

"You right?" the Doctor asked, noticing she looked as though she was in pain.

"I'm fine," she said after a moment, forcing herself to smile. "Can I lay down for a bit?"

"Sure," said the Doctor. He led her to a small room with a bed and Tilly flopped down on it, looking exhausted.
