A/N - I do not own Doctor Who. I just wanted to make this story because it would have been a cool season of Doctor Who. Enjoy and review please :P
'Little blue box,' said Christina as she came up to the Doctor, 'just like you said. Come on Doctor, show me the stars.'
The Doctor smiled at her and said 'No.'
'What?' Christina replied, the smile sliding off her face like watered down paint.
'I said no,' The Doctor replied.
'But I saved your life! And you saved mine!'
'So?'
'We're surrounded by police! I'll go to prison!' She replied, panicking and glancing around her.
'Oh,' the Doctor said, grinning cheekily. 'When you put it that way, let's go!' The smile returned to Christina's face, as the Doctor clicked his fingers and the doors of the blue box opened. 'Ladies first,' the Doctor moved aside to allow her in.
She turned to face the Doctor, walking in backwards. 'Won't it be a bit, I dunno, cramped with two people in a Police Box?'
'Have a look for yourself,' the Doctor shut the doors of the TARDIS just as the police were advancing.
Christina turned around to look in the TARDIS, and her mouth dropped. 'What the…?'
'Yeah, it's big. Well, where do you want to go?'
'How did that happen?'
'What? The big-thing? It's just dimensionally transcendental. Bigger on the inside,' he said as he walked over to the console and started the TARDIS. 'Where to? Future or past? Or maybe present? Earth? This solar system? The next one? Or the other side of the universe? This ship can take you anywhere, any when, and all in a few seconds!' As he said this, he was running about the TARDIS console, preparing it for launch.
'How about,' Christina said, 'we go to Jupiter. It's my favorite planet.'
'Never been there before, so, let's go!' The Doctor typed the coordinates into the TARDIS and, with a few pumps of a leaver, a turn of a knob, and a good kick, the TARDIS took off, streaming through the vortex, taking them to their destination, and a whole new adventure.
