A/N: Part 3 is here! So, I've been up for longer than I should have been, missed a few days sleep. There may be spelling and grammatical errors, which I hope to hunt down and fix. Either way, I hope you enjoy this chapter.

Kari stood there behind Martha as she rebooted the monitor once again. The Doctor and Jack had charged off to the radiation chamber, and she knew that Jack would be in there by now. "We lost picture when that thing flared up. Doctor, are you there?" Martha called, hoping that the Doctor could hear them.

"Receiving, yeah. He's inside" The Doctor replied.

"And still alive?" Martha asked him, not noticing the way that Kari was chewing on her thumb nail and glancing at the professor every now and then.

"Oh, yes."

"But he should have evaporated. What sort of a man is he?" Professor Yana asked in awe. He knew that it shouldn't have been possible for anyone to survive being in that room full of radiation, especially without any protection.

Kari couldn't stop herself from speaking, even though she was trying to just keep herself to herself. "One of the best men I know, and he's my brother." She told them quietly, getting a bit of a smile from Martha.

"The Doctor and Kari sort of travel through time and space and picks people up." Martha explained. "God, I make us sound like stray dogs. Maybe we are."

"They travel in time?" Professor Yana asked, looking over at Kari. She just gave him a small, worried smile back, because she knew he was starting to hear more than just the drum beats in his head now.

Martha hadn't noticed anything, she was too busy making sure the communication didn't cut out any more. "Don't ask me to explain it. That's a TARDIS, that box thing." She said, nodding over to the wooden blue box in the laboratory. "The sports car of time travel, he says."

Kari was more interested in listening to the conversation that was going on between the Doctor and Jack. Even though she pretty much already knew everything they were going to say, she still wanted to hear it, because the Doctor's voice was her distraction.

"When did you first realise?" The Doctor said, as Jack worked on getting the coupling fitter correctly.

"Earth, 1892. Got in a fight on Ellis Island. A man shot me through the heart. Then I woke up. Thought it was kind of strange. But then it never stopped. Fell off a cliff, trampled by horses, World War One, World War Two, poison, starvation, a stray javelin. In the end, I got the message. I'm the man who can never die. And all that time you know. You both knew." Those final words that Jack said made Kari feel guilty. She had always known, and she had seen him in between, when he hadn't know, and she had never told him.

"That's why I left you behind. It's not easy even just looking at you, Jack, because you're wrong." The Doctor told him.

"Thanks." There was a hint of sarcasm in Jack's voice as he replied and struggled with the coupling.

The Doctor knew that he had to explain more, just like Kari knew he was. Going to. "You are, I cant help it. I'm a Time Lord. It's instinct. It's in my guts. You're a fixed point in time and space. You're a fact. That's never meant to happen. Even the TARDIS reacted against you, tried to shake you off. Flew all the way to the end of the universe just to get rid of you."

"So what you're saying is that you're, er, prejudiced?" Jack asked him, finally managing to get the coupling to fit into place. It wasn't an easy task, but he was the only man who was capable to do it.

"I never thought of it like that." The Doctor admitted, causing Kari to roll her eyes in the laboratory.

She heard Jack chuckling a little. "Shame on you. Kari was never like that. In fact, she couldn't seem to stay away from me." Jack said. "While you left me behind, she kept finding me. How comes you call me wrong, and she calls me her brother?"

Kari couldn't help but frown, that was not meant to be part of the conversation, it was something completely new, and she didn't know where it was going to lead. "Well, it's Kari. She always knew, Jack, from the moment she met you. She saved you that day, because she knew what was coming, that you would become a fixed point."

"Yeah, and look at all the trouble that caused. The pair of you had a massive fight and pretty much split up." Jack said, causing Martha to look at Kari with wide eyes.

Kari just shrugged at her. "It was a long time ago. He was a right pain in the backside, and so was I. We used to fight a lot in those days." The look on Martha's face just said that she wanted more of an explanation than that. "Not now, Martha. We have other things to be dealing with."

"Well, it was still early for Kari when all that happened." She heard the Doctor telling him. "And I suppose that didn't help towards my moods back then." The Doctor said. Kari had already started to understand why he was always in such a mood with her back in those days. She was so early in her time line, so far behind with everything that had happened, that the Doctor didn't know how to handle it.

"Yeah, you were kind of jealous. Didn't exactly approve of me call her Princess, did you?" Jack mentioned. "Last thing I remember, back when I was mortal, I was facing three Daleks. Death by extermination. And then I came back to life. What happened?"

Kari knew that she had to speak up, she didn't want to know what had happened, if things were changed, because she hadn't been there yet. "Spoilers, Harkness, spoilers." She said, leaning over Martha just to make sure that they could hear her.

"Oh, you and you're spoilers, Kari." She heard the Doctor moan.

"Yeah, and? I haven't been there yet, and I'd really like it if you didn't spoil it for me by telling me everything that happened." Kari warned him. "And don't you dare say that I already know, because we both know that it isn't always as accurate as that. All you need to know, Jack, is that it was the final act of the Time War." She said, knowing that it needed to be said at that point. Out of the corner of her eyes she could see that Professor Yana was struggling with it, that he was starting to remember. "And Rose isn't just gone, Jack." She added quietly, thinking about Rose Tyler, her friend.

"Kari's right. She's not just living on a parallel world, she's trapped there. The walls have closed." The Doctor told him, knowing what Kari was getting at.

"I'm sorry. I went back to her estate, in the nineties, just once or twice. Watched her growing up. Never said hello. Timelines and all that." Jack said, now struggling with the next coupling.

"Do you want to die?" The Doctor suddenly asked him.

But it seemed like Jack wasn't really all that willing to go into that topic, not when he knew Kari was listening. "Oh, this one's a little stuck."

"Jack, just answer him, it's okay." Kari told him, making sure that he knew she wouldn't mind and that she understood.

"I thought I did. I don't know. But this lot… You see them out here surviving, and that's fantastic." Jack finally said. "And how could I ever leave my Princess?" After he said that, he managed to get the coupling in place and move on to the final one.

"Hmm, good answer, Jack." Kari mumbled, hearing both him and the Doctor chuckling a little at her comment. Both the men knew that she cared about them, like she cared about all of her friends and the people she met.

"You might be out there, somewhere." The Doctor informed him, trying to move the conversation along and onto something that wasn't likely to either annoy or upset Kari. She was having a hard enough time as it was, she really didn't want to make it any worse.

"I could go meet myself." Jack replied.

Kari couldn't help but roll her eyes as the Doctor replied. "Well, the only man you're ever going to be happy with."

"This new regeneration, it's kind of cheeky."

Martha just shook her head. "I never understand half the things he says." She said, before noticing the professor, and how he was on the verge of having a complete break down. "What's wrong?" Martha asked him, walking over to him with Kari and Chantho.

"Chan, professor, what is it, tho?"

"Time travel." The man replied, shaking his head a little. "They say there was time travel back in the old days. I never believed. But what would I know? Stupid old man. Never could keep time. Always late, always lost. Even this thing never worked." He told them all, before pulling out a fob watch. Kari's eyes fixed on it, and she could feel both her hearts pounding in her chest at the sight of it. "Time and time and time again. Always running out on me."

Martha was looking at the watch in his hand, completely stunned. "Can I have a look at that?" She asked, making Kari close her eyes and take a deep breath.

"Oh, it's only an old relic. Like me." The man said, holding it out in his hand still.

"Where did you get it?" Martha asked, looking at it cautiously. They could only see the back of it, but even Martha suspected it could be something more.

"Hmm?" I was found with it." He said, the expression on his face looking as if he was trying to remember everything. "An orphan in the storm. I was a naked child found on the coast of the Silver Devastation. Abandoned, with only this." The professor told them, looking at the watch once more.

The next words that Martha said made Kari's eyes snap open "Have you opened it?"

He looked at the woman in slight confusion. "Why would I? It's broken?"

"How do you know it's broken if you've never opened it?" Martha said, challenging the man. She was pushing him. Pushing to find out what he knew, to find out of she was right.

Kari cleared her throat and held her hand out. "Well, how about I take a quick look at it. I'm pretty good at fixing broken things, you know." A moment later and the watch was carefully lying in her hand. And she could hear it, she could hear a voice calling out, mentioning the drums, the never ending drums.

"It's stuck. It's old. It's not meant to be. I don't know." Professor Yana told them, as Martha reached out and flipped the watch over. When she did, her eyes widened in shock. There, on the front, was an inscription similar to what she had seen before, when the Doctor had once made himself human. "Does it matter?"

Martha quickly looked at Kari, and the fear in her eyes told her everything she needed to know. "No. It's nothing. It's… listen, everything's fine up here. I'm going to see if the Doctor needs me." Martha said, looking between Kari and the professor.

"Go on then, Martha. I'll make sure the professor is all right." Kari told her, trying her best to keep her voice light and happy, ish. She just stood there and watched as Martha ran off, off to tell the Doctor what they had just found. "Don't worry, professor. We'll soon have you and Chantho both off to Utopia with everyone else."

She was hoping, that without the watch in his possession, he wouldn't think on it so much, that he wouldn't be able to break the perception filter around it until the Doctor arrived at least. She wanted the Doctor there, she needed him there. "I hope you boys are nearly finished down there." Kari called to him, trying not to sound too anxious.

"We're almost done. How's everything up there?" The Doctor asked her.

"Good. Everything is good." She lied. "But Martha is on her way down to you, just so you know. In case you need any more help." She didn't like lying to him, but she needed to try and buy them some more time. If she couldn't stop it from happening, she could at least try to do something. Kari didn't care about altering the timelines now, she cared more about the Doctor, her friends, and everyone else that would suffer.

'Oh, right. Well I think we're actually good down here. Almost there." The Doctor replied, starting to get a little bit suspicious. "Are you sure everything is okay?"

Kari couldn't help but roll her eyes. "Doctor, nothing has been okay since we stepped out of the TARDIS, why would they suddenly be okay now?"

"Right, sorry. Won't be long now." He told her, letting her know that they would be going soon. Only she had another meaning in her to what he had said, to what wasn't so far away now.

Kari turned her attention back to the professor, and she could see that the time was getting closer to where he would want to open the watch. She held it tightly in her hand, trying to ignore the voices coming from it, working their way into her head. No matter what the Doctor and Jack said, she was at least going to try for a different outcome from this little adventure to the end of the universe.

"Chan, are you all right, tho?" Chantho asked her, noticing that her eyes had started to glaze over slightly.

She quickly nodded at her, forcing a smile onto her face. "Yeah, I'm fine. Just wish the lads would hurry up, you know."

"Chan, are you sure? You are shaking, tho." The blue woman was quick to tell her.

Kari only then noticed that her hands were both shaking, and the rest of her body was getting ready to follow. "It's just been a long day. I'm tired and I'm hungry." She told her, actually telling the truth. "Been to the end of the universe and ran away from the Futurekind. Not exactly a peaceful day."

Chantho smiled at her, understanding that it must have been rather difficult for her to find herself in a place like that. "Chan, you should sit for a bit, tho." She said, ushering her over to one of the chairs and making her sit down. "Chan, I will make sure everything is okay, tho." She told her, before wandering back over to the monitor.

Everything was set, the rocket was ready to launch now. And all Kari could do was stare at the watch that was now sitting on the table in front of her. She couldn't hold it anymore, the noise, the drum beat, it was getting too much for her. But she knew she had to keep it away from Professor Yana for a little while longer.

"Kari? Kari, are you okay?" The Doctor suddenly called to her, his voice full of panic.

She let out a sigh. "Martha's told you, hasn't she?" That was the only reason she could think of for him being so worried.

"Can he see it, Kari? Can he see the watch?" She looked up and saw the professor staring at the watch on the table, his eyes transfixed on it.

"Uh, yeah. He can. But I'm trying to keep him away from it, until you get here. I know who he is, Doctor. I told you we should never have stayed. You should have listened to me." Kari was annoyed that no one would listen to her, that even though she knew what was going to happen, other people still thought they knew best.

"Who is it? Which Time Lord survived the war?" He called to her, the panic in his voice rising. Kari knew that the moment she told him, things would just get a whole lot worse.

Even though she was speaking to him through her mind, she still took a deep breath before answering him. "It's the…" She was cut short when the watch that was on the table was swiped away by the old man. "Professor?" Kari asked cautiously, as he inspected the watch. "It's broken, just like you said. It's a shame, because it's rather pretty." She told him, slowly getting up and taking small steps towards the old man.

"Kari? Kari, who is it? Is everything okay?"

"I'm sorry, Doctor. He has the watch. And… and he's going to open it. Just… remember what the Face of Boe said, his dying words. Think, Doctor." Kari called to him, keeping her eyes firmly fixed on the man with the fob watch. She followed him as he went and looked at the Doctor's spare hand in the jar.

"Chan, Yana, won't you please take some rest, tho?" Chantho asked him, clearly worried about the way he was acting.

Kari just watched, as everything around them all started shaking. The Doctor had done it, he had sent the rocket to Utopia, at the end of the universe. But that mean something else was going to happen, and her eyes filled with fear as she watched the professor stand in front of the TARDIS and open the watch. "No… no, no, no, no." She whispered to herself, knowing that she had failed to do anything. She should have tried harder, to have kept the watch away from him, to have taken it to the Doctor instead of just sitting there.

A golden light streamed out of the watch and towards the old man, and even Kari could feel the Time Lord essence returning into the mans body. "Chan, Prosfessor Yana, tho?" Chantho called in concern, causing the man to slowly turn and look at her. The look in his eyes just showed that he was no longer the same man.

"It's okay, Chantho, just stay over there." Kari said, pulling the woman back so that she was further away from the old man. "Professor?" She then asked looking at him. "Professor, are you okay?"

The man didn't say anything, as he went and pulled a lever, glancing at Kari every now and again. "Chan, but you've locked them in, tho."

He just ignored the woman, as he kept on walking. "Not to worry, my dear. As one door closes, another must open." The man told her, before powering down the defences around the silo, allowing the Furturekind that were eagerly waiting outside to gain entrance.

"Chan, you must stop, tho." Chantho protested. "Chan, but you've lowered the defences. The Futurekind will get in, tho."

Kari had inched her way closer and closer to the TARDIS. She knew that he was going to steal it, along with the Doctor's spare hand that he had been rather interested in now. She was getting ready to at least try to stop him another way, since keeping the watch away from him hadn't worked.

"Chan, Professor, I'm so sorry, but I must stop you. You're destroying all our work, tho." Chantho then said, causing Kari and the old man to look over at her. She was now holding a gun firmly in her hands, and pointing it at him.

"Oh. Now I can say I was provoked." He spat at her, picking up one of the live cables that had killed Jack. "Did you never think, all those years standing beside me, to ask about that watch? Never? Did you never once think, not ever, that you could set me free?"

Kari remembered what was going to happen next, and knew she had to do something. "Don't!" She shouted, getting their attention. "Leave her alone. How was she to know? The Time Lords never came this far, how was anyone supposed to know?"

He snarled at her. "You knew, didn't you? That's why you took it away from me, trying to stop me from being free." He said, now starting to approach Kari with the live wire. "The Angel of Time who knows everything."

"Please, it doesn't have to be like this, you know it doesn't." Kari pleaded with him, actually starting to panic a little more. She had never anticipated that he would decide to go for her. "Just wait for the Doctor, and listen to him. There is so much that you don't know, about what happened, about how everything has changed."

"The Doctor!" He growled, inching closer a little more to Kari. "The Doctor and his perfect life and his perfect wife."

"Listen, I don't know everything, okay? I haven't been with the Doctor that long, it's still early for me. Please, please, just listen…"

"Do you know who I am?" The old man hissed at her, causing Kari to nod. "Than who am I? Tell me, what is my name?"

Kari swallowed the lump that had formed in her throat. The man truly was terrifying her. "Master. You are the Master."

The Master smiled, such an evil, wicked smile, and then thrust the cable forward towards Kari. Only it never touched her, as Chantho had jumped in the way and the live cable had electrocuted her instead. "I suppose you are worth more to me alive." The Master decided, grabbing Kari tightly by the arm.

He started pulling things apart, making a complete mess of all his work, when a voice called through the locked door. "Professor! Professsor, where are you? Professor! Professor are you there?" The Doctor shouted. "Please, I need to explain. Whatever you do, don't open that watch."

"It's too late, Doctor. He opened the watch." Kari told him, feeling like she had let him and everyone else down. She had tried to stop Chantho from being killed by him, to save her, but she had failed that. Chantho had sacrificed herself to save Kari instead.

"Professor! Open the door, please. I'm begging you, Professor. Please, listen to me. Just open the door, please." The Doctor begged, having heard Kari but being too worried about what was going on with the man she was locked in a room with to answer.

Everything that happened next, happened in a bit of a blur for Kari. She heard a gunshot, and something else smashing. The Master had a tight hold of her arm, holding the Doctor's spare hand under his other arm, as he dragged her into the TARDIS. He shut the door just as the Doctor reached it, quickly locking it so that he Doctor couldn't get it and pulling Kari over to the console with him.

"Deadlocked." The Master said triumphantly.

"Let me in! Let me in!" The Doctor shouted from the other side of the door, hammering on the wooden panelling. "I'm begging you. Everything's changed! It's only the three of us! We're the only ones left! Just let me in!" He continued to shout.

"Killed by an insect. A girl. How inappropriate. Still, if the Doctor can be young and strong, then so can I." The man said, looking at Kari with a glint in his eyes. "The Master, reborn."

"Doctor, I really hope you have a plan here. Because he isn't going to let me go anytime soon, and I am about to lose my mind." Kari said, closing her eyes tightly and huddling down the side of the console at the golden regeneration energy surround the old man. "Please, get me out of here."

"Kari, it's okay. Everything is going to be fine, I promise you." The Doctor assured her. "No matter what happens, I will get you out of there."

Kari didn't like the way he had said that, it made her feel like he was going to leave her with the Master. The Doctor didn't know everything, he didn't know what the Master was going to do, where he was going to go. But Kari did. "Don't make promises you can't keep, Doctor."

Before the Doctor could say anything else, there was a manic laughing coming from across the console, causing her to carefully peek over. "Now then, Doctor." The Master called, sound very excited. As he tested out his new voice. "Ooh, new vice. Hello, hello. Hello!" He said, going low to high before returning his tone back to normal. "Anyway, why don't we stop and have a nice little chat while I tell you all my plans and you can work out a way to stop me, I don't think."

"I'm asking you really properly. Jut stop. Just think! Let Kari go, an listen to us." The Doctor shouted from outside of the blue doors. He was worried about her, about what was going to happen to her.

"Use my name." The man asked, staring at Kari, the evil glint in his eyes scaring her even more.

"Master. I'm sorry. Please, just let Kari go." The Doctor pleaded. "Please."

The Master grinned a little. "Tough. You're precious little Kari is mine now. Oh, just looked at her, so scared." He said, taking a few steps closer to Kari. "All those years of following you around, going wherever you went. Times change."

Kari didn't know what the hell he was talking about, or what the hell was going on. All she did know was that it seemed like he had absolutely no plans on letting her go, which meant she was going to have to think of a plan herself.

"Let her go. Just let Kari go!" The Doctor shouted, angry and frustrated that he couldn't do anything apart from try to convince him to let her go.

"Oh, I don't think so." The Master said, grabbing a hold of the lever on the console. "End of the universe. Have fun. By bye!" He called, before sending the TARDIS off into the time vortex. "Now then, what shall I do with you?" He said, looking at Kari.

She really was completely and utterly scared. She didn't know what to do, she didn't think there was anything that she could do. "I… I don't…" She stuttered, trying to back away from him.

"Like a deer caught in the headlights." He said, now standing right in front of her. "Oh, how young you are. So young, so beautiful…" The Master trailed off as he tucked some of Kari's hair behind her ear. She was just standing there frozen, both her hearts pounding in her chest.

"Don't… don't touch me." Kari managed to say in a whisper, her voice shaking as well as the rest of her.

All that happened was that the grin on the Master's face grew bigger. "Oh ho, look at you, trying to be brave." He said, holding Kari's chin between his thumb and finger. "Always so brave for the Doctor."

"I said, don't touch me." Kari said, only a little louder, as she pulled her head out of his reach. She knew she couldn't let him intimidate her, she knew she had to do something to get back to the Doctor.

"You know, we were friends once." The Master told her, not trying to touch her but still too close to her for her liking. "All three of us. The Doctor, the Angel, and the Master. Oh, the adventures we had."

Kari had no idea what he was getting at, but she was starting to form a plan in her head. "Spoilers." She said, a hint of a smile on her face. "I haven't done any of that yet. This… this is the first time I've met you. And you're not really making a very good first impression."

A frown formed on the Master's face, before it suddenly turned into a grin once more. "Well then, I had better change that then, hadn't I? Go pack a bag, we're not going to be in residing in the TARDIS."

She knew exactly what he meant. "Because she's going to be turned into the ultimate paradox machine?" Kari queried, still standing there and looking at him. As the minutes passed, she seemed to find just a hint of courage.

"Oh, brilliant. You know all about it, that is fantastic. And, since I have you, there is no way that you can tell the Doctor." The Master said, bouncing around the console. "Now, off you go, my sweet little Angel. Pack a bag, we have a world to conquer."

Kari slowly backed away from him, before turning and running as fast as she could to her room. "Come on, Sexy, give me something. There has to be something that I can do." She whispered to the ship as she went. She knew she had to come up with some amazing plan, otherwise she would be spending the next 18 months living with the Master.

A thought made her stop dead in her tracks, and cause her shiver to go down her spine. "Oh, that was not nice." She mumbled, having just seen an image of her taking the place of Lucy, the Master's human wife. Kari began to move again when the corridor started to shake a little. "Right, get to my room and make a plan from there." She muttered.

The moment she stepped into her room and closed the door, she heard it locking behind her. "Uh, I do hope that was you." She said, getting a hum in response from the ship. "Okay, so now what do I do?" She asked, before noticing an enveloped perched on her desk. "Where did that come from?"

Kari went over and picked it up, vaguely remembering when she had gotten it. Ianto had delivered her a dress, and they had gone to where Professor Lazarus decided to try and change what it meant to be human. The hand writing on the front of it looked familiar, and it took her a few minutes to realise that it was her own handwriting.

'Oh, you have got to be kidding me. I'm sending myself letters now? Is that what my life has come to?" She asked herself. Kari was stressed, and she had gone past her breaking point and was now just running on what little hope she had left. "Suppose I might as well see what I have to say to myself."

She carefully opened the envelope, and pulled out a folded piece of paper. "I don't fancy spending a few years with the Master. How about we take the quick way?" Kari read from the note. "The Doctor needs us, so grab you're bag and let's go." She read it over a few more times, just to make sure she hadn't missed anything out. It wasn't until she turned it over, that she saw the string of numbers on the back. "Oh, lovely. Now I get it."

A moment later and she had half crawled under her bed, reaching for her bag that River had given her so long ago now. Once she had it, she let out a small cheer. Then she was overcome with guilt as she looked around her room and her home. "I'm sorry, for what he is going to do for you. If I stay, I might be able to…" A hum from the ship cut her off. "The Doctor and I will stop him, I promise you." She said, pulling the leather strap out from her bag and fixing it around her wrist. "I mean it, we'll stop it." Her fingers typed in the coordinates into her vortex manipulator.

After one last glance around the room, she whacked her hand down on the device. She knew that he Master would soon go looking for her, and probably be more than just a little annoyed when he found out that she was going, but she didn't care, she needed to get away from him and get back to the Doctor. He was probably panicking as it was, and she didn't want him to worry. She could get to him, and tell him everything that was going to happen, and hopefully stop it all.

A/N: So, I hope you all liked the chapter. I've already finished the next episode, and yes it is another 3 parter. That would be the reason why I have been lacking sleep, I've been too engrossed in writing this story.

Quick note, SOPA is NOT trying to take down fanfiction or any other form of fandom. There are a few scaremongers out there, as well attention seekers. Before getting all panicked over something like that, always go and do some research.

Thank you to everyone who has favourited/followed the story. It's amazing how that little notification can just brighten up my day. Now, an absolutely massive thank you to everyone who has taken the time to review. Reading them always makes me smile, so thank you so much.

Well, I hope you enjoyed this chapter, and are looking forward to the next one. I have to admit, this is going to be a long and difficult journey to get through. I have a few tricks up my sleeve.

Until next week!

Pippa.
