"So... Where are we going?" Clara grinned as the doctor slid around the console, pulling levers and spinning wheels.

"The third moon of Laxtri! You'll love it- the sky is actually green! And the people!" They landed with a large bump, and he gestured towards the doors. "After you, Miss Oswald."

Clara grinned as she bounced towards the doors and flung them open, before pausing.

"Er... Doctor? The sky is... Not green." The doctor peered over her shoulder as she looked at him skeptically.

"Ah... Sorry." He winced. Clara sighed.

"Where are we?"

"The moon! In the 51st century! How did we...?" He spun to look at the console, but Clara stepped out, smiling as she stared around her.

"Wow..." She murmured. "Wait, how are we breathing? And how is there sunlight?"

"Artificial sunlight and atmosphere! You lot are clever aren't you. There's a whole colony of humans here- hospitals, schools, offices, homes, even a university! An entire world, on the moon." He grinned at her, but the smile faded as he caught sight of the armed guards marching towards them.

"Oh, that's extremely not good." He muttered as they surrounded them.

"You will come with us. Do not resist, or force will be used." A mechanical voice said.

"Robots!? Robot soldiers! On the moon!" The doctor laughed as he held up his hands in the air. "Hey, get off of my tardis!" He cried as another set of soldiers surrounded it with a large crane. They were marched across the green where they'd landed towards a tall glass building.

"Ok. Not normal." The doctor mumbled as they approached.

"What?" Clara hissed.

"The doors- they're air locked shut." He whispered back as they walked through them. Clara flinched as thy closed behind them with a powerful hiss, a clanking confirming they were well and truly secure. "We're in a fake atmosphere! Why would they need airlocks?" Clara opened her mouth, then shut it again as human soldiers came forward.

"Prisoner transfer complete." The automated voice said, before the group of robots marched away back outside.

"Please follow us." The expressionless soldier said, and they marched on through the long corridors.

"Where are you taking us then?" The doctor asked as they walked. The man didn't respond.

"Oh, come on! If you're going to kill us, can we at least know about it?" The doctor exclaimed. The soldier scowled.

"We're not going to kill you. We're under orders to bring you before the high council." He told them coldly. Before long, they were lead into a large room that was dominated by the large table in the centre, where several people sat.

"Oh, hello!" The doctor smiled. "I'm the doctor, and this is Clara. I think there's been some mistake-"

"We know who you are doctor." A short, round man stood up and walked towards them, frowning sternly. "What are you doing here?"

"Ah, see, we kind of took a wrong turn somewhere. Was supposed to be going to Laxtri, not entirely sure how we ended up here..." The doctor trailed off when he saw their faces. "I think I'm missing something. Do you get that feeling, Clara?"

"Just a little." She said, exasperated, putting her hands on her hips. Before anything else could be said, the doors were flung open and a familiar teenage hurried through.

"Governor! Slight misunderstanding- these two are earlier in their time streams than before. They genuinely have no idea what's going on!" AJ said breathlessly. The man scowled.

"Are you sure?"

"Of course I'm sure!" She crossed her arms, frowning at the man. "Release them, now. I'll deal with them."

"Miss S-"

"Governor! I will deal with them, I promise. Just release them." She interrupted him quickly, frowning at him. They stared at each other for a long moment.

"Fine. But you are responsible for them and their actions." He finally relented. AJ nodded curtly.

"Understood." She gestured to the doctor and Clara and walked out with them trailing after her. As soon as they'd turned the corner and were out of sight she spun on her heel and glared at them.

"Are you two crazy coming back here!? Thank god governor stupid face doesn't have a clue about time streams or you'd both be locked up by now! Honestly, of all the stupid things to do..." She ranted at them, keeping her voice low so as to not alert the guards.

"What?! We didn't actually mean to come here... It was an accident." The doctor protested. AJ blinked in surprise.

"Wait, you really are earlier in your time stream?" She questioned. The pair nodded.

"Huh. That's complicated." She commented. "So... Have you met me before?"

"Well, obviously-" Clara began, but the doctor quickly put his hand over her mouth.

"Have you done England?" He asked, not removing his hand. AJ nodded.

"The first time you met me, and I'm assuming you haven't since... Doubly complicated." She mused while Clara, confused, licked the doctor's hand in frustration.

"Ew! Clara!" he snatched his hand away and jumped up and down, waving his hand in the air before finally wiping it on Clara's dress.

"Oh, stop it you two." AJ grabbed their hands and hauled them down the corridor, eventually dragging them into an lift at the end.

"Identification?" A smooth voice sounded as the lights flashed and the doors closed. Clara looked vaguely uneasy, but AJ was perfectly calm.

"Smith, AJ, number 2029."

"Acknowledged."

"Floor 46." The lift whirred and Clara had the unsettling feeling she was about to fall through the floor, before they came to an abrupt halt and the doors slid open. AJ led them out through another maze of corridors before coming to a stop and scanning her palm to allow them access to the room they'd come to.

"My tardis!" The doctor bounced out and threw his arms around his ship, murmuring as he scanned her with his screwdriver.

"Oh please." Clara raised an eyebrow at him, which he ignored. She wandered around the room, looking at the equipment. There were several large tables covered in papers and books, as well as holographic computer terminals and the walls were covered in sketches and drawings, photos and calculations. Stairs that spiralled up in the middles of the room led up to another level, on which she could see bookshelves filled with various references. She let out a gasp as the room suddenly brightened, moving closer the the wall that had suddenly become a glass window. She stared out in shock and wonder, looking over the huge city of which she'd only seen a tiny part earlier.

"Luna city. Not terribly inventive with names, are we?" AJ came to stand beside her, looking out over the buildings and parks in front of her. "Over one million people live in this colony. The elderly, children and babies. Scientists and artists and politicians and soldiers. An entire culture. An entire world."

"Where are they all?" Clara wondered, not seeing a single person in the streets below her, despite the bright sunshine. AJ looked at her questioning, pointedly gesturing to the city below them. "No, I mean why aren't they out there? Apart from the soldiers and the men in the room before, there's not a one single person."

AJ laughed delightedly.

"Oh, doctor, she's good." Her lips twisted into a smile as she looked at him, but he didn't return it. He walked over to them, face serious.

"I was wondering that as well. The Luna colony is not a military establishment, the only base is a protective one built to politely dissuade would-be attackers. So why the escorts? And as Clara said... Where is everyone? Why does a SIMPLE teenage girl hold such sway over the high council, and have access to what is obviously one of the highest security establishments on this colony? It isn't normal, not by a long way. What, AJ Smith, aren't you telling us?"
