The Doctor was holding his sonic screwdriver in this right hand and Jim's phone in the other.

"Why do you need my phone again?" Jim inquired grumpily.

"I'm using it to find where the teleport goes too and stop asking." He said spinning it round.

He stopped and licked his lips, "got it, this way!"

He led the way down the corridor until he reached a fork. Then he spun the phone around again.

Still don't get it." Jim said sulking.

"Last time, it uses sort of your phone signal to collaborate where it goes too. Like a source of power, we just have to follow to where the power supply starts."

They continued on, spiralling through the corridors endlessly.

Rose opened her eyes wearily, "Doc..."

She lifted her head and found her legs and arms tied down. She tried to wriggle out but they were too firmly tied. She was in an upright position however, tied to a board against the wall. No one was in sight and she seemed to be in yet another slimy room of mouldy, dripping concrete walls.

She gulped down her fears, "hello?"

No answer but her echoing voice.

She tried to get her right hand out by twisting her wrist round but nothing would get them out. Hope they're not planning to starve me... No, they need me for something otherwise they would have just killed me.

The door banged shut beside her but before she could look her eyes were covered.

"Do not try to look." A cracking husky voice spoke in her ear.

"Who are you?" Rose shot at it.

"You will find out later! Be still! This hurt a bit maybe. More if you struggle."

She felt a sharp jolt of pain from her left arm and as she tried to move it away it shot down her arm like a razor sharp knife. She called out in pain.

"Stupid girl! You moved! No moving! You won't leave!" it spat at her.

Then a jolt of pain in her right arm and she couldn't help flinching at the pain which made it even worse.

"Ouch! STOP IT!" she cried out hopelessly.

"Stupid. Hurts a bit! Stop moving!"

Then there was a jolt of pain in her left leg and one more quickly in her right. She gritted her teeth against the pain and frustrated tears rolled down her cheeks.

"What-are-you-doing!" she hissed through her teeth.

"Surprise," It said.

With its free hand it unclenched Rose's teeth and dropped in a drop of some foul liquid before holding shut her mouth.

"Swallow, it help with pain," and he disappeared out of the room in the blink of an eye.

Rose spat out the liquid as soon as he had gone and looked down at her throbbing arms.

"Ouchy!" she said crossly.

After a few minutes her arms went numb along with her legs. Dazed and tired Rose closed her eyes.
