The Doctor untangled the dinosaur from his net and pushed it into the large bird-cage he had found in one of the libraries. It was funny, whenever he used this bird-cage he was always catching something scaly with four legs. It hadn't been him using it last time though. Not with the hands he had now.

'Four things and a lizard,' He muttered to himself, remembering.

He heard the door creak open behind him. He turned around and saw the girl standing there, looking around with a frown on her face. She wandered further in, then stepped outside again. She reappeared in the doorway. 'Is going crazy infectious?'

He smiled to himself. He liked this bit.'Depends.'

'On?'

He fiddled with something on the console. 'If you're telepath, possibly.'

'And are you?'

'Insane or telepathic?'

'Either.'

'Both.'

The girl bit her lip, considering. She nodded. Her dark curls bobbed. 'Okay.'

'Okay?'

The girl shook her head. 'Not okay.'

'Okay then.' He clapped his hands together. 'So, on or off?'

'Sorry, what?'

He gestured to the console. 'Time machine. Space travel. To put it simply: would you like to see something cool?'

The girl stared, her mouth hanging open slightly. Then she returned to her frown. 'I have school tomorrow.'

'It's a time machine. It travels in time.' He hopped down from the platform.

'I have to get back before dinner.'

'As I said, it travels in time. That's what time machines do.'

'My parents don't know where I am.'

'Neither do mine.'

The girl nodded. Then nodded again. 'Okay.' A smile broke across her face.

'Okay?'

She positively beamed. 'Okay.'

The doctor held out his hand 'I'm the Doctor.'

'The Doctor?'

He lowered his hand. 'That's my name.'

'Doctor.' It wasn't a question, but she said it sceptically.

'Just the Doctor.'

'Okay, the Doctor.' The girl stuck out her hand. 'I'm Noelle.'

The Doctor shook her hand. 'Okay.'

She grinned. 'Okay.' She stopped grinning. 'You can read my thoughts.'

'Only when I can be bothered. Which I can't, for the majority of the time. Your thoughts are safe.'

'Okay.' Noelle nodded. 'Okay, so where are we going? Venus?'

'If you like. Not much there at the moment, though.'

'The moon?'

'Of course.' He hopped back up to the console, pushing buttons, flicking switches, pulling levers.

Noelle looked around when the sound started. 'Is it supposed to do that?'

'Yes.' The Doctor remembered what River said. About the brakes. 'Sort of.'

'That's reassuring.'

The noise stopped. The Doctor smiled over at her. 'Take a look outside.'

'Don't I need a spacesuit?'

'Only if you want one; the Tardis provides oxygen.' He saw the look on her face.'It's complicated.'

Noelle nodded. 'Okay. Okay. Okay.' She realised she was repeating herself and stopped. 'I say okay a lot.' She looked at the door, determined. 'Okay.' She marched over and pushed both doors wide open.

The view was unbelievable. The actual moon was pretty un-amazing, just grey and rocky, but the blue orb floating in the inky blackness left Noelle speechless. Well, almost. 'Can I stand on the moon?'

'If you want to.'

'But when someone else gets up here, won't they be like, 'Who the hell left these here and why were they wearing trainers?' Won't that be a problem?'

'A whole hospital disappeared off the face of the earth and landed on the moon once. I don't think it matters much anymore.'

'Wait, what?'

'It was the Judoon. A platoon of Judoon.'

'A platoon of Judoon on the moon?'

'Exactly.'

'Try saying that when you're drunk.' Noelle muttered to herself. She took a deep breath. 'Okay.' She stepped out. She took another step. And another. She ran a ring a round the Tardis. The Doctor appeared in the doorway, watching her. 'We're on the moon!'

The Doctor raised his eyebrows in reply.

'This is unreal. How is this real? This isn't real. Am I dreaming? I'm dreaming... I am dreaming, aren't I?'

'You're not dreaming.'

'That is exactly what you would say in a dream.'

'It's quite unlikely that we're both dreaming - well, I say that. It has happened before.'

'That's not possible... is it?'

'It's happened to me.'

'Do you always get caught up in trouble like that?'

'Not all the time. Well, actually - not the point.'

'What is the - Hey! Ow.' She rubbed her arm. 'What the hell was that?'

'Electric shock function,' He said, holding up his sonic screwdriver. 'Good for April fools. I love April fools. Had twelve in a row once. Also not the point. What was that for? It was to check if you were dreaming.'

'Did that work last time?'

'Ah, no. Not quite.'

Noelle glared at him. She punched his arm.

'Hey!'

'Just returning the favour.' She smiled sweetly. 'So we're probably not dreaming.'

'It's highly unlikely.'

'So what now then?' She looked at her feet.'... Are you going to take me back?'

The Doctor's forehead creased. 'Do you want to go back?'

Noelle grinned. 'Not yet.'

'Well then.' The Doctor smiled, rubbing his hands together. 'How about take a little trip back in time?'
