The Doctor grimaced slightly.
"I thought he was dead?" He glanced at Jack, who obviously had no idea who they were talking about.
"He lives on through me. It's a new experiment he was testing. Soul slicing it's known as. In my mind I have a voice, kind of like a conscience; that's my father talking to me." The woman's eyes grew wider and darkened. The Doctor knew that look. It was the same one he had, only evil. She could obviously see across the whole of time and space.
"Whoa. So let me get this straight, we're going to take orders from a woman who claims she can hear her Dad talking to her in her head?" Jack asked raising one eyebrow.
"Don't." Warned the Doctor. "She's not lying. I can see it in her eyes."
"You're clever Doctor, but are you clever enough?" The woman smiled. "There are a series of puzzles you will face along the way. Each more difficult than before. You have an hour. I suggest you go."
The Doctor walked forward slightly, but the creatures hissed.
"Doctor," Jack murmured. The Doctor stopped a little way from Rose.
"I'm going to find that antidote and escape with Rose and her Mum in one piece." He said defiantly.
"Oh really. Well you'd better hurry, you've wasted two precious minutes."
The Doctor ignored her comment and turned walking past Jack and through a door on the other side. Jack followed him, glancing back at Rose who looked so helpless, her eyes screaming out.
"Got a plan?" Jack muttered as the Doctor opened the door.
"Nope," the Doctor replied.
The door shut with a clang behind them and they found themselves in a room with three doors, each one had an inscription above it.
"What do they say?" Asked Jack recognising the Gallifreyan script, even though he couldn't translate.
"The first one says 'Speak Truth And Enter Here'," the Doctor said frowning. He moved one the next. "This one says "Speak Foe And Enter Here' and the last one says, 'Lunch Room'."
"You're joking right?" Jack asked raising one eyebrow.
"Funnily enough no." The Doctor replied.
"So, which one?" Jack looked at the two optional doors. They were exactly the same in colour, height and distinction.
"This one." The Doctor said pointing to the second door.
"How do you know?"
"I Don't." The Doctor hissed something in Gallifreyan and the door opened.
"What did you say?"
"Foe," Jack thought for a long time as they went down the next very dark corridor before finally realising the reason the Doctor had said 'foe'.
After a while they came to a large pit, full of spikes.
"She's very imaginative isn't she?" The Doctor commented. "Not exactly the brightest of enemies I've faced."
"Hark at you," remarked Jack. "You're full of it aren't you?"
"Yup." The Doctor began examining a series of levers on the wall. "I'd say we have to pull the right lever to release a bridge or something to get across the pit."
"What happens if you pick the wrong one?" Jack asked suspiciously. The Doctor pointed somewhere over Jack's shoulder. He turned and saw several large, lethal looking spikes sticking out of the wall opposite.
Jack gulped. "Great."
The Doctor pondered for a few minutes.
"You better pick the right one." Jack warned as the Doctor reached out.
"Look, it's either pick one and hope, or wait for these scales to kill us. Which would you prefer?" The Doctor asked irritably. Jack didn't reply, just threw the Doctor a look of disdain after his back was turned.
"Ok, I' think I've got it." The Doctor said.
"You think?" Jack sounded nervous.
"I know." The Doctor said firmly, pulling the lever.
Nothing happened. Then with an almighty screech, like a cat being strangled, a bridge lowered and the Doctor cried out in joy.
"Wahey. See, I told you I'd do it."
"Never doubted you."
The continued down the corridor and found a door at the end. Once opened they found themselves in a very tall room with a single glass box in the middle. A box, which contained the antidote.
The Doctor took out his sonic screwdriver and proceeded cautiously.
"Stay behind me." He warned.
"Wow. Protective aren't you? I thought you were just this way about Rose." Jack smiled knowing he'd hit a nerve.
"Look. We're already in a life threatening situation, I don't need you getting yourself into another one." The Doctor growled.
They crossed the room and after checking the box with his screwdriver the Doctor removed the antidote.
"That was rather easy." The Doctor commented.
"Too easy." Jack agreed.
"Well done Doctor. The only problem with your rescue mission is that you're not going to leave that room alive." Came the woman's voice over the loud speaker.
"Well we'll see about that." The Doctor replied cheerily.
"Even if, by some miracle, you do get out, you won't live. There's only enough antidote for two people and if I've guess right, which I'm sure I have, you will give it to the others." The voice said rather more happily than necessary.
"You're forgetting one thing." The Doctor said. "I'm a Time-Lord. I can regenerate."
"Doctor, Doctor, Doctor." The voice laughed. "I know you can regenerate. Which is why I added a special formulae to stop you being able to do that."
Jack looked at the Doctor and could see the look of determination in his face.
"Cleverer than I thought." He muttered.
"Good-bye Doctor. It was nice knowing you, and your hunkey companion." The voice laughed.
Jack smiled slightly but hastily hid it when the Doctor turned to look at him. A large hole opened in each of the walls and water began to pour out. It wasn't long before the Doctor and Jack were floating at least twenty foot off the ground.
"I hope you can swim." The Doctor said grimly.
