A/N : Thanks for the encouraging reviews, they are fab as always :). Well this is the chapter were you find out exactly what exactly the experiment was. I wasn't really sure if this was a good idea or not, it's a bit of a twist to the story but I'm going to risk it anyway and hope you like. Review as always!

Reinette stopped Teresa before she'd had chance to type in the access codes to the building. Reinette needed to know what was going on, what the daleks were up too and what they were doing to her friends before she could go any futher. Teresa looked at her questioningly."What's wrong?"

"I need you to answear my questions before we go on" Reinette said firmly. Teresa looked at her and hesitated but after a few moments, nodded slowly."What are the daleks doing to them? I mean you mentioned an experiment? what is it?". Teresa looked at her uncertainly."They're my friends, please, if you've done something to either of them, I needed to know what it is. One my friends is already dead". Teresa glanced away after she mentioned Mickey. She decided she may as well tell Reinette now they're on the same side but she wouldn't admit to killing Mickey.

"To answear your question, I'll have to go right back to the very beginning" Teresa said and Reinette urged her to go on."The daleks were all wiped out after a terrible war with the time lords. I believed, like the rest of the universe, that they were extinct. But I soon discovered four had survived, a small group of daleks that went around known as the cult of Skaro. The daleks , although they think very highly of themselves, are not a particulary intelligent race without help so they recruited me" she paused for a moment. Reinette frowned at her.

"But why would they want you?"

"Because I'm part time lord. I have my mothers human form but I have my father's time lord intelligence and that's what they needed to help rebuild the dalek race" she continued and Reinette listened intensely."Well anyway they found me when I was just eighteen and at the most vunerable point in my life. My mother had disowned me, my sister had no intereast in me what so ever as she was this famous actress who everybody adored and she had no time or tolerance for a geeky half sister" Reinette could not help notice the tone of bitterness in Teresa's voice."I joined the daleks because they told made me believe it would be worth my while and all I could think about at that time was revenge. I didn't really care about who got hurt just as long as I'd made my mother hate me as much as I possibly could " Teresa ignored the sympathatic look Reinette was giving her."The daleks found this isolated facality and we turned most of the rooms into labs for experiments. We snatched various species from all over the universe as part of our plan to rebuild the dalek race". Reinette looked at her confused.

"But in what way were you using them and how did you rebuild an entire race?" Teresa hadn't realised how much she dreaded getting to this part. It was sickening to even admit.

"When we snatched a species, we usually took one female, one male. We chained them to medical tables in our lab and knocked them out while we did it so they really didn't get much choice in the matter. Our scientists took a sex cell from the male and female, mixed them together and left them to grow into embryos. Except when we mixed the DNA together, we added this liquid that would make the growth alot faster than it usually would for that species so it would take onlya few hours and then we would plant it into the female. After that, she would give birth to it's child and then we'd take it, mutate it, remove it's emotions and turn into a dalek" Teresa gulped at the last part. Remorse had hit her fast and hard these past couple of days. She didn't understand why but her conversation with the Doctor had contributed alot to it. He had somehow broken through the barriers she'd built over the last thrity years for herself. She choked back tears then continued with her story. "It's been thrity odd years since we began doing this and now there are at least one million daleks up in spaceships in the sky, killing things thanks to me " Teresa said with a tone of self-loathing. Reinette followed her gaze to the sky above."A couple of months ago, the daleks decided they needed a emperor. They already had a leader but it wasn't enough, they wanted an intelligent emperor who could lead them into battle against all other species without anything getting in their way, particulary the Doctor. They considered it and decided it couldn't be me they still needed me in human form but they were desperate and that's when it came to them. It would be a perfect revenge on their greatist enemy in the universe and that's when they decided it must be him. They were going to steal the Doctor and do an experiment on him and his companion, Miss Tyler".

"Why miss Tyl- I mean Rose?" Reinette corrected herself and looked at Teresa curiously.

"All they told me was that she was compatible" Teresa said quietly as soon as she said that Reinette remembered something and decided to bring it up.

"When I first met the Doctor, these robots from the future came after me because they said I was compatible. They needed something specific, is that what the daleks want from Rose?"

"I don't really know. The daleks kept me in the dark about most things, all I was allowed to know was about the experiments" she replied, feeling a bit drained.

"But you haven't done anything to them yet have you?" Reinette looked at her in alarm. Teresa glanced away once more.

"I'm sorry, I really am. And when I last saw Miss Tyler, she seemed to be suffering some rather unusual side effects" Teresa typed in the access codes in the machine.

"The Doctor will be furious when he learns what you did to Rose. The daleks are his greatist enemies..."

"I know and I never really thought about my actions until the day I met him" Teresa admitted sounding angry with herself.

"The Doctor has that affect on people" Reinette agreed and followed Teresa through the doors.

Rose was feeling a little bit better now but she still felt sick and wasn't over the fact that Mickey was dead. The Doctor was still holding her in his arms and neither had said a word in a while. Rose didn't know what the hell they'd done to her but something was wrong. Rose felt sleepy and yawned which didn't go unnoticed with the Doctor."Here, lie down" he said, pulling off the covers for her to slip into bed. She took off her jeans and left on just her t-shirt and knickers. The Doctor was just about to get up when she pulled him back down.

"Lie with me, please" she whispered , he nodded and crawled in beside her. Underneath the covers Rose looked for his hand, took it and fell to sleep snuggled up to him. The Doctor smiled, he could get used to this. But unfortunately, a few moments later, just as he was getting used to it, their door flung open and two purple guards barged in.

"Get them" one of them ordered and they marched to the bed and pulled the couple out. Not again, the Doctor thought in irritation, just before he was sedated. Rose gasped as she was also shot to sleep with a tranquliser dart.

Teresa made a fake I.D card for Reinette and they stepped into the elevator that led them to the level on which was Rose's and The Doctor's room. She followed on behind her and they stopped at a steel door. Teresa pressed her hand to the machine on the door and it flung open but to Teresa's horror there was nobody in there . "Where are they?" Reinette asked looking at Teresa who had paled dramatically.

"They've been taken which must mean..." Teresa began but drifted off.

"What? Teresa what does it mean,?" Reinette looked at her worriedly.

"They're here. The daleks are here and they're going to kill the Doctor"

"What for? I thought you said they needed him" Teresa looked at her with a grave expression.

"I should of mentioned earlier. After the experiment is a sucess, they kill the male and after the female has given birth, they kill her too. The daleks don't see the point in letting them go alive and then the child immediately get's taken straight to the lab to be converted into a dalek". Teresa looked like she wanted to cry. "I've seen so many of them get mutated, it's horrible, it cruel. And I never did anything to stop it.What have I done?". Reinette's face had gone white just like Teresa's had earlier. Teresa looked haunted for a few moments but pulled herself together."Reinette, we need to go to the daleks and stop them. I will not have this happen again because of me. I'm sick and tired of all of it and if they kill me then I will finally of got what I should of had coming a long time ago". Reinette stopped her as she began walking down the hallway towards the lift.

"Don't say that, your nothing like them. You obviously still have your emotions and your sorry for everything you've done. Nobody deserves to die, not even you. They're the real murderes aren't they?" Reinette said softly looking at Teresa who was struggling to hide her feelings. She wasn't so good at it these days and now she knew she had to tell the woman she was the one who killed her friend in cold blood.

"I killed Mickey Smith" she confessed sadly and Reinette's sympathatic expression hardened.

"Why, what did he ever do to you?"

"Nothing. Nothing at all. I simply panicked and didn't think it through. I know that there is no point in saying sorry when I can't change what I've done but I'm going to say it anyway since it's the only thing I can do now." Teresa said quietly.

"We should just go and save my two living friends before they get into even more trouble" Reinette replied, not looking at her and walking off towards the lift. Teresa sighed, pulled herself together and joined Reinette in the lift.
