"Well this doesn't look like home!" Said Amy hopping out of the Tardis, Rory followed soon after.

"I didn't do anything" Said the Doctor confused. He darted around the console to catch up with them. He stopped suddenly retraced his steps and grabbed something that was close to the door.

"Wait so the Tardis landed itself" Rory looked around. They were in a corridor with other corridors leading of it. Every wall was blank and painted white, they all looked identical and there was no one to be seen or heard. It was silent.

"This isn't one of those times where you 'accidentally' landed us somewhere exciting is it?" Amy sighed "And why have you got an umbrella?"

In his hand the Doctor was twirling a multicoloured polka dot umbrella. "Felt like it, and when has that ever happened?" Said the Doctor leaning on his umbrella and pulling out his sonic screwdriver from his tweed jacket to scan the air.

"Like when we were supposed to be going to Brazil and ended up in Yorkshire!" Mocked Rory

"And when you were coming to pick me up and then was two years late!"

The Doctor grunted "Stop being so..." He said, flapping his arms around. "Not everything goes badly for us" He began to walk down the biggest corridor.

"Yes, it does" said Rory

The Doctor turned to talk to them, walking backwards down the corridor "You never know, the people here might me friendly"

Suddenly a boy clutching a bag running from the corridor to the right, slammed in to the Doctor taking them both to the floor. The boy was flustered and out of breath but the Doctor still recognised him immediately: "Luke Smith!" He cried standing up and brushing himself off "What are you running from?" The Doctor turned just in time to see a Slitheen waddling up the corridor. A massive, repulsive green monster with long sharp claws and eyes as dark as night.

"Ah..." The Doctor frowned and scratched his head. He leaped towards the creature "Stay Back!" He yelled pointing his umbrella towards the slimy green monster. "Amy, Rory get back"

The Slitheen laughed cruelly "Your threatening me with an umbrella!"

"Well it was worth a try" he shrugged lowering his 'weapon'. "Who are you, why are we here?"

"You're guess is as good as mine, Doctor!" The Slitheen flexed its claws and blinked its cruel, black eyes.

Even in the drama the Doctor looked pleased at being recognised, he smiled and straightened his collar. "You've heard of me then"

The Slitheen snarled "You killed my family when they tried to invade. I have waited all my life for this chance of revenge, you shall be a fine hunt" he took a step forward and the Doctor took a step back.

"Yes sorry about that" said the Doctor, a smile on his face to prove that the apology was not sincere.

"Doctor?" Amy called, half hiding behind Rory

He turned towards the couple briefly "Yeh there was a little problem at Downing Street, all sorted." The Doctor turned back and continued to distract the Slitheen by talking utter nonsense.

"Downing Street" Amy mumbled, impressed.

"What's he doing" whispered Rory, nodding in the direction of Luke. Amy got a better look at him now, he looked about eighteen and was wearing a T-shirt and jeans. 'Same as any average teenager' she thought. He was crouched behind the Doctor mixing and then smelling various vials of different coloured chemicals that he was pulling out of the bag.

Suddenly he jumped up and shouted "Got it!" As if waiting for him, the Doctor hopped out of the way and Luke through the vial full of liquid at the beast. Strange noises started to rumble from the Slitheen and its eyes grew distant. Quick as a flash the Doctor opened his umbrella shielding himself and Luke from massive chunks of Slitheen flying at them. The Slitheen had exploded.

Amy stood in shock over what had happened. Her an Rory were coated head to foot in green slime. She made an attempt to wipe away the sludge from her face but her hands were covered too and it only made it worse.

"Doctor!" She screeched "What was that?"

"Acetic Acid" smiled Luke, triumphant and excited from defeating the creature. He looked both of them up and down and smiled even bigger than before, "don't worry, it washes out".
