A/N- Sorry another really short chapter but this is the one where the plot is solved the next chapter is pure loving FLUFF!

Ps- sorry I've nicked a line from Harry Potter GOF it's not mine

Sorry again as I've nicked a line From DOOSDAY! I don't own it!

'Who are you, what do you want?' the Doctor asked the wisp, his sonic screwdriver clasped in his hand.

'I am of the Dimension Shifters and I want that girls brain!' and with a laugh that made even the Doctor shiver, the Dimension Shifter cackled. The Doctor longed to look behind him, to check that Rose and Jack were ok but he didn't want this thing to learn his weaknesses so early in the game.

'Rose's brain? You don't want that it's just filled with fluff and stupid earth songs' the Doctor replied trying to keep his voice cheery for Rose's sake. He could hear her snorting with outrage behind him but he couldn't worry about her reaction now, he had a Dimension Shifter to figure out.

The Dimension Shifter swayed silently on the spot before saying softly-

'It is not the fluff or songs I wish to take Doctor!'

'Well what DO you want?'

'KNOWLEDGE'

His brow creased in confusion and his eyes sparkled dangerously.

'Of what?'

'I know that the girl looked into the TARDIS and I wish to obtain the information that she soaked up about times that have been, are, and will be!'

The Doctor turned to Jack not daring to look at Rose.

'Jack search the databanks on Dimension Shifters and read what it says'

After a couple of impatient clicks and tuts from Jack he soon started to reel off the information.

'Dimension Shifters- made out of only atoms and can take the form of anyone or anything that it has information on' Jack paused and took a deep breath

'Ok Doctor, basically they're info banks living databanks, they source unknown knowledge of their kind and steal it from the carrier by um, dismantling the brain and removing the necessary cells'

The Doctor heard rose flinch somewhere behind him and he called over his shoulder-

'Don't worry Rose I won't let it take your brain'

It sounded like he said stuff like that everyday, thought Rose.

But then again, he probably does. The Doctor faced the Dimension Shifter once more.

'So you don't want to kill us, take over the world or destroy the human race, you just want TARDIS knowledge?'

He looked thoughtful for a second, before buzzing the sonic screwdriver onto the control panel. He shouted over the noise at the wisp of smoke in front of him-

'WELL HERE IT IS!'

Before, the heart of the TARDIS was exposed to the Dimension shifter and it shuntered around the control panel, shaking furiously. Then after a few moments in imploded and all that remained of it was two piles of sand, one blue and one yellow.

The TARDIS closed and Rose walked over to the Doctor who was kneeling down by the sand. He smiled wanly at her.

'I hope you like your brain Rose, cos I just saved it from becoming a library book!'

He called over to Jack who was standing in front of the grinding central column.

'Hey Jack, go and get an empty jar from the kitchen!'

A/N- I know it's a really short chapter, but I do hate writing in chapters because-

Mine are normally really short

And if I put all the chapters together it looks much more impressive!

Oh sorry I forgot my Disclaimer, so tell you what, I'll write an all over disclaimer on my profile in case I ever forget to write one!
