'Bigger on the inside'

'Smaller on the outside' said Julian and Dax together.

'Careful!' yelled a voice from inside. 'I'm trying to-' the voice broke off and started coughing. Through the smoke, a man staggered to the door with a fire extinguisher in his hand. His hair was ruffled and sticking up everywhere and his face and clothes were both singed. He leaned against the doorway, wobbling, for a moment, firing the extinguisher back into his ship. Another flood of smoke flew out, making him and the officers cough. He coughed for a couple more seconds before the fire extinguisher fell from his hand and his collapsed in a heap just inside the doorway. Julian knelt down next to him with the medkit as the smoke began to clear. Dax knelt down next to him.

'He looks human…' She, looking him up and down. He was wearing a tweed jacket over a pale blue shirt both of which were burnt and torn. An untied bow tie hung loose around his undone collar. Julian flipped open his tricorder and scanned him.

'Nothing's broken and it all looks fairly regular. Except…' Julian paused and suddenly the man's eyes snapped open.

'There's two hearts' he finished. He sat up quickly and looked around at everything.

'Where am I?' Sisko stood next to him.

'You're on the Federation station Deep Space Nine near Bajor.' The man looked startled.

'The Federation…' he muttered to himself. He jumped up and before pausing and turning to the startled officers to offer an explanation.

'Sorry about this, not really sure what happened, I'm the Doctor, hello everyone.' He flashed a smile and waved around. 'I really shouldn't be here; I need to go.' He quickly took off his jacket and pushed open the door, flapping the jacket in from of him as he went inside. A lot of the smoke had gone but there was still some. The officers stood startled for a moment when suddenly the station shook. The Doctor appeared next to Julian in the doorway.

'Sorry, sorry! It seems there's been some kind of malfunction. Let me just-' the station shook again, harder, knocking the officers' feet from under them. Julian fell backwards into the Doctor and they both tumbled back into the box. Before they could get back on their feet, the station shook again sending the Doctor back to the floor and Julian headfirst into the edge of the door. Lights flashed in front of his eyes and he fell to the floor, dazed, as the door slammed shut. The lock clicked and the engines whirred into life. The Doctor pushed himself towards the door with a yell and tried to pull it open but it had locked itself. Frustrated, he sprang up to the console and started frantically pressing buttons and turning dials. As he pulled a final level, a shower of sparks flew off from the console, making him spring away with a yell. He looked up at the central engine confused.

'What's wrong with you, then?' he muttered. Julian groaned and the Doctor looked over as he wobbled to his feet, looking around at the chasm that, a few moments ago, looked no bigger than a turbolift in wonder. The Doctor smiled. He loved the look on people's faces when they saw inside for the first time. He leapt down the steps out of the way of another shower of sparks.

'So this is your spaceship?' asked Julian curiously, forgetting about DS9.

'Well… spaceship, time-ship; it does both. It's called a TARDIS' he explained, 'Short for 'Time And Relative Dimension In Space. And yes; it's bigger on the inside.' Julian nodded.

'Some sort of inter-dimensional displacement?' he asked. The Doctor nodded, looking impressed.

'Good guess.' he said. Julian smiled. The TARDIS started to shake again and they had to hold onto the railing by the steps to stay on their feet. The Doctor bounded back towards the console with Julian following.

'Here, you seem reasonably clever, keep this reading under 100 it might help to stabilise the flight.' As Julian got to grips with that, the Doctor frantically ran around the console trying everything he could think of to gain control. As he danced around the TARDIS continued to shake and tilt at an unnatural angle. The Doctor lost his footing and slid towards the edge of the console area, knocking down Julian with him. They scrambled on the floor for a few seconds until suddenly there was a bang as the TARDIS made a hurried landing and then everything was still. The two men climbed slowly to their feet and stood still for a moment. The Doctor looked up at the engine, still glowing, but the background noise. Unlike its normal never-ending sigh, it was more metallic, like the static on a broken computer. The Doctor flicked a few things on and off but nothing happened. He threw up his hands.

'We'd better find out where we are then.'
