The Doctor turned around and threw his hands out.

"Well?" he asked, "What do you think?" Clara paused for a minute, staring around the massive... well, she didn't know quite what it was, but it was definitely massive.

"I- I think it's-"

"Bigger on the inside? Smaller on the outside? Yep, it is." The Doctor said cheerfully.

"I was going to say that I think it's a big step up from the coffee shop, actually." The Doctor pouted.

"You're supposed to do the whole 'bigger on the inside' bit. That's always fun." Clara raised her eyebrows.

"So what actually is this place?" she asked, walking up the ramp towards the main console. There seemed to be some sort of pillar coming out of the middle of it, and none of the controls looked very official; They all looked like they'd been cobbled together from the contents of a kitchen drawer.

"This is the TARDIS- that is, Time And Relative Dimensions In Space." At her confused look, he elaborated. "It's a spaceship. And it travels in time." Clara's eyes widened.

"You have a time machine?! How is this not on the news? I'm pretty sure we'd know if time travel had been invented. Unless... is this a military thing?" She tilted her head suspiciously.

"Good!" said the Doctor, "Except, you're extremely wrong. But I am impressed." He strode around to the far side of the console and Clara followed him.

"So what's the truth then?" she asked.

"I'm a Time Lord. The last of them, actually." Suddenly, his eyes looked very old, and Clara wondered how she hadn't noticed them before. "So I travel the universe, and fight the bad guys. And there's an awful lot of running involved." Clara put her hand on top of his where it rested on the console.

"Well, I'm always up for a run." She smiled at him. She got the feeling that he'd been too lonely for too long. He grinned, and looked young again. Still, Clara could see the shadow of those old eyes behind the mask of enthusiasm.

"Alright then!" All of a sudden, he was all action again. "What do you want to do? Anywhere and anywhen in the universe; it's all yours." Clara paused again.

"So... I tell you where or when to go and we'll just.. be there? We can seriously do that? You better not be making this up." There was something about the Doctor that made Clara sure he was telling the truth, but in her head it all just sounded so ridiculous.

"I'm not making it up. What shall we do?" He asked.

"Well..." Clara hesitated. "There is something I've always wanted to see..."

"What is it?" asked the Doctor.

"I've always wanted to see Ancient Greece, back when it wasn't ancient." The Doctor grinned and fiddled with the controls on the console.

"Greece it is!" he said, and pulled a lever.
