The four emerged from the Tardis. Amy and Rory in a new set of clothes and the Doctor now umbrellaless. Him and Luke were talking nineteen to the dozen, the Doctor about his adventures in Time and Space (and his new face) and Luke about his latest adventures with his mum, Sarah Jane, on Earth.
Luke had earlier explained that he had woken up close to his mum in corridors like these. They had wondered the corridors together until a wall slid down and separated them. He then stumbled across a small room filled with various tool:, guns and knives etc. but all Luke took was a bag of chemicals (what he thought he could get the best out of). He had then bumped into a Slitheen and then bumped, more violently, into the Doctor.
The young boy stopped mid sentence, "You're gonna find Mum, right?" A look of concern crossed his face.
"Yes I will," smiled the Doctor, he slapped Luke on the back "and until we do I think your mother's more than capable of looking after herself" He walked forward and pressed his ear against one of the white walls.
Luke laughed half-heartedly. Amy could see he was still worried. They both watched as the Doctor stared intensely at the wall, licked it and then smacked his mouth. She chucked to herself. "Honestly, he looks crazy... but he gets results" she smiled a warm, friendly smile that instantly made Luke feel relaxed. "What is it then Doctor?" She smiled walking over.
"An ordinary wall" he sighed disappointed.
Rory looked around and then stopped, he frowned and turned to the Doctor. "Have we moved?"
"No of course we haven't Rory" cried the Doctor striding over to him.
"But Doc-" the Doctor but his hand over Rory's mouth and looked at his surroundings in confusion. In annoyance Rory tried to say something but it came out muffled.
"Shhhh, thinking" he mumbled and then walked away from Rory, pacing.
"Doctor we've moved" said Amy bluntly
"Shhhh" he put his finger to his lips and motioned for the others to do the same which they did.
"Maybe everything else has moved" said Luke clearly nervous as to whether he was allowed to speak.
The Doctor paused for a second then laughed and clapped his hands together. "Boy genius right there" he said and ruffled Luke's hair. He pulled out his sonic screwdriver and pressed his ear against the wall once more. The sonic glowed a ghoulish green and hummed at several different frequencies before he finally peeled himself from the wall with an excited exclamation. "There's tiny, tiny, little mechanisms in these walls, which means somewhere something is controlling them." He yelled as excited as a child on Christmas.
"You're loving this aren't you?" Asked Amy a smile stretching across her face
"Well someone bought us here for a reason, I think it's time we found out what it is"
Suddenly the walls changed, new corridors opened up and once open passages became closed off by crystal clean, white walls. They were separated, Amy was with Luke and Rory was with the Doctor and none of them could reach the Tardis.
