A/N: Here is the next chapter. I apologise now for any spelling or grammatical errors that are present. Having trouble focusing at the moment to do my final check through, I will get them done later. Well, enjoy!

"Hey, you okay?" The Doctor asked Kari, bringing her out of the little world she had found herself in since they had arrived.

She gave him a quick nod as they carried on walking through the packed corridors. She knew where they were, and she knew where they were heading. She wasn't happy, and she had that sinking feeling in the pit of her stomach.

"Kistane Shafe Cane?" The little boy, Creet, called out as they walked through the corridors there was packed with people.

"End of the universe and here you are. Indomitable!" The Doctor exclaimed. "That's the word. Indomitable. Ha!"

"Is there a Kistane Shafe Cane?" Creet called once more.

Finally a woman stood up and looked over at the group of people walking towards where she had been sitting on the ground. "That's me." She said, her cloths dirty and ragged.

Padra, the man who had led them to the silo, looked at her, hope in his eyes. "Mother?" He said, before rushing over there, hugging the woman and seeing his brother there with her as well. He was finally back with his family.

Martha couldn't help but smile at the scene before them all. "It's not all bad news."

Kari remembered what happened next, and she looked over at Jack, giving him a warning glare as a young man stood up. "Jack, don't. Help the Doctor instead." She said, noticing that he was working on getting a certain door open.

"It's half deadlocked." The Doctor announced as Jack went to help him. "I need you to overwrite the code. Let's find out where we are." He said, using his sonic screwdriver on the door.

The pair of them worked on the door, and soon enough they had it opened, only for the Doctor to almost fall straight down a rather large drop on the other side. Kari and Jack both reached out and grabbed hold of him, pulling him back. "Gotcha." Jack said with a smile as the Doctor thanked him. "How did you cope without me?"

Normally, Kari would have smiled at something like that, but she just didn't have it in her to smile. Even when they were gazing at the gigantic rocket before them, she couldn't be amazed like they were, especially Martha. "How that is what I call a rocket."

That was when it dawned on the Doctor. "They're not refugees, they're passengers." He announced, getting a slight nod from Kari, just to confirm that he was right.

"He said they were going to Utopia." Martha mentioned, remembering something that Padra said when they arrived at the silo. He asked if they could get him to Utopia.

"The perfect place. Hundred trillion years, it's the same old dream." The Doctor told her, taking Kari's hand once again and giving it a gentle squeeze. "You recognise those engines?" He said, glancing at Kari and then at Jack. He knew she wasn't going to tell him anything, she was being extremely quiet and that was always a bad sign.

"Nope. Whatever it is, it's not rocket science." Jack replied, also noticing how Kari was acting. "But it's hot thought."

The pair of them quickly shut the door again, stopping the extreme heat flooding into the corridor. "Boiling. But if the universe is falling apart, what does Utopia mean?" The Doctor wondered.

That was when Kari noticed an old man approach them, and she tensed up in fear. She was pretty sure that she was forgetting to breathe, she was just that terrified. Right now he looked harmless, he acted harmless, but she knew differently, she knew the truth.

"The doctor?" The elderly man asked, looking directly at Jack.

Instead Jack pointed to the Doctor, who still hadn't noticed what was wrong with Kari. "That's me." He said, causing the old man to grab his hand and shake it rather vigorously.

"Good! Good!" The man exclaimed. "Good. Good. Good. Good. Good. Good. Good. Good. Good." He continued, dragging the Doctor away from the rest, and in turn taking Kari with them.

'It's good. Apparently." The Doctor called back, as Martha and Jack both jogged along to keep up with them.

"Not good. Definitely not good." Kari mumbled, as she was tugged along with the Doctor and the old man. She was getting very close to her breaking point. There was so much running through her mind, so many thoughts about what was going to happen, how it was going to have an impact on all of her friends and the people she cared about. She was struggling as it was to keep everything all bottled up, she knew it wouldn't be long until she totally lost it.

Eventually, the group were pulled into a laboratory where they were greeted by a blue alien. "Chan, welcome, tho." She said to them, bowing her head slightly, being very polite to them.

The Doctor didn't get a chance to say anything, as the old man was still pulling him around, now showing him all the different equipment that he had in there. "Now, this is the gravitissimal accelerator. It's past its best, but it works." The old man explained, as Kari finally managed to pull her hand away from the Doctor.

She walked straight over to where Martha and Jack were introducing themselves to the blue alien, Chantho. "Captain Jack Harkness." He said, giving Chantho a rather flirtatious smile.

The Doctor turned to look at him ad gave him a firm warning. "Stop it."

"Can't I say hello to anyone?" Jack asked, getting slightly annoyed with not being allowed to do anything with the Doctor around.

"No, you can't." Kari told him, grabbing a hold of his arm and resting her head against it. She wanted someone to take notice of how she was feeling, to actually start to understand how serious it all was. They all seemed to be too wrapped up in everything that was going on, that they had completely forgotten Kari's warning.

Lucky, Jack had finally noticed. "Hey, what's the matter, Kari?" He asked her quietly while the Doctor was shown some more equipment.

"Everything. Everything is the matter, Jack. I don't… I don't want to be here." She said, glancing at the old man out of the corner of her eyes. She knew who he was, Professor Yana. It was a good cover up, she would give him that, but it was still all an act in the end as far as she was concerned.

He didn't really know what to say, all he knew was that she was pretty scared. "Come on, everything is gonna be just fine, you'll see." He told her, pulling his arm from her grip and giving her a one armed hug.

Kari closed her eyes and took a deep breath. "I wish you were right, I really do. Anyway, I think the Doctor might need your help."

Jack nodded at her, knowing that there was nothing that he could say that would help to ease her mind or make her any less afraid. "So, what have we got here?" He asked, going over to the Doctor and the professor.

"And all this feeds into the rocket?" The Doctor asked, as Jack pasted Kari over to him, hoping that just being near him would calm her down slightly.

"Yeah, except without a stable footprint, you see, we're unable to achieve escape velocity." The professor explained. "If only we could harmonise the five impact patterns and unify them, well, we might yet make it. What do you think, Doctor?" He asked, a glimmer of hope in his eyes. "Any ideas?"

The Doctor looked at the old man, his glass still perched on his nose and an arm now tightly around Kari's waist. "Well, er… basically… sort of… not a clue." He finally admitted.

"Nothing?" The professor asked, the disappointment evident in his voice.

"I'm not from around these parts. I've never seen a system like it. Sorry." Even the Doctor sounded a little disappointed that he couldn't help. But Kari knew better, and she really wished she didn't.

"No, no. I'm sorry. It's my fault. There's been so little help." The man told him, while Martha started to rummage through the backpack that Jack had finally taken off and dumped on a chair.

"Oh, my God!" She cried, pulling out some sort of canister with a hand bubbling away inside of it and placing it down on a chest that was being used as a table. "You've got a hand?" She asked, as Jack smiled at the object. "A hand, in a jar. A hand, in a jar, in your bag."

The Doctor was now over there, looking at the hand that Martha had found. "But that… that… that's my hand." He said, sitting down on the chair and forcing Kari to sit on his knee.

"I said I had a Doctor detector." Jack told him, glancing at Kari and wondering why she hadn't smiled or laughed at that. Usually she would have, but she was just too quiet.

"Chan, is this a tradition amongst your people, tho?" Chantho asked, standing there in her clean, white, lab coat and looking very confused.

Martha looked from the hand and over to Chantho. "Not on my street." She exclaimed, before turning to look at the Doctor and Kari. "What do you mean, that's your hand? You've got both your hands, I can see them."

"He lost it. Christmas day. In a sword fight. On top of a spaceship." Kari muttered. She knew she needed to pull it together, and get on with it, but it wasn't as easy as it seemed.

The look on Martha's face just showed that she was shocked. "What? And you grew another hand?"

"Uh, yeah. Yeah, I did, yeah. Hello." He replied, giving her a quick wave with the hand that was attached to the rest of him.

The professor looked at him, completely and utterly confused. "Might I ask, what species are you?" He said.

The Doctor leaned back, taking Kari with him a little as he prepared to tell the man who he really was. "Time Lord, last off." He said, point between himself and Kari. "Heard of them?" The professor just shook his head at him. "Legend or anything? Not even a myth?" Once again the man shook his head. "Blimey, end of the universe is a bit humbling."

"Chan, it is said that I am the last of my species too, tho." Chantho told them all.

That was when the Doctor realised he didn't actually know the names of the other two in the room, and even Kari hadn't let anything slip. "Sorry, what was your name?"

"My assistant and good friend, Chantho." The professor replied, speaking for the blue woman. "A survivor of the Malmooth. This was their planet, Malcassairo, before we took refuge."

"The city outside, that was yours?" The Doctor asked her, his hand finding Kari's and starting to fiddle with the ring on her finger.

Chantho nodded at him. "Chan, the conglomeration died, tho." She informed him, the sadness seeping through her voice at the thought of her home and people.

"Conglomeration, that's what you said, Kari." He said, giving her a nudge and a smile. She managed to give him the smallest of smiles back, which was better than nothing.

"But you are meant to say sorry, Doctor." She told him, her voice coming out in almost a whisper.

His smile faded a little. "Oh, yes. Sorry."

"Chan, most grateful, tho."

But Martha still hadn't forgotten where the conversation had started. "You grew another hand?" She asked him, still trying to wrap her head around it all.

"Hello, again." The Doctor said, putting his hands on Kari's waist and helping her stand before getting up himself. "It's fine. Look, really, it's me." He said, holding his hand out towards Martha.

Slowly, Martha took a hold of his hand and shook it. "All this time and you're still full of surprises." She said, letting out a laugh as the Doctor clicked his tongue on the roof of his mouth.

"Chan, you are most unusual, tho."

There was a slight grin on the Doctor's face as he once again grasped hold of Kari's hand. He knew this whole trip was difficult for her, and all he could do was try to reassure her that everything was going to be fine. "Well…"

"So what about those things outside?" Jack asked, moving the topic of conversation onto something a little more important than the Doctor's spare hand. "The Beasty Boys. What are they?" He said, referring to the sharp-toothed humans that had been chasing them to the silo.

"We call them the Futurekind, which is a myth in itself, but it's feared they are what we will become, unless we reach Utopia." The elderly man informed the group.

The Doctor looked at him, once again twisting the ring around on Kari's finger. He couldn't really explain why he seemed to do that, it just seemed to happen some times. "And Utopia is…"

The professor looked at him as if he was crazy, and then at the rest of the group. "Oh, every human knows of Utopia. Where have you been?"

"Bit of a hermit."

The man looked at him, and the way that the Doctor's hand was entwined with Kari's. He hadn't failed to notice the ring that she was wearing as well, and came to a conclusion. "A hermit with a wife and friends?" He asked sceptically.

The Doctor just shrugged at him a little. "Hermits United. We meet up every ten years and swap stories about caves. It's good fun, for a hermit. So, er, Utopia?" He said, completely skipping over the part about Kari being his wife. He couldn't say anything because he didn't know where she was up to. He hadn't had the chance to ask her or really talk to her at all since she had arrived.

The man led them over to a computer unit. "The call came from across the stars, over and over again. Come to Utopia. Originating from that point." He said, pointing to a particular spot on the screen.

"Where is that?" The Doctor asked, looking intensely at the screen. He had passed Kari over to Jack, only because he knew that he would try to get her to relax while he worked.

"Oh, it's far beyond the Condensate Wilderness, out towards the Wildlands and the Dark Matter reefs, calling us in. The last of the humans scattered across the night." The professor explained. Both Martha and Jack had solemn looks on their faces as they listened, while Kari was doing her best not to listen at all.

The Doctor was still interested, though. "What do you think's out there?"

"We can't know. A colony, a city, some sort of haven? The Science Foundation created the Utopia Project thousands of years ago to preserve mankind, to find a way of surviving beyond the collapse of reality itself." It was explained to them. "Now, perhaps, they found it. Perhaps not. But it's worth a look, don't you think?"

She managed to block everything out, if only for a few minutes, but it was a few minutes of relief that she had. Kari's had hadn't stopped hurting, and although she knew she wasn't about to be whisked off somewhere else, it was still worrying her. She was putting it down to stress, stress of knowing what was going on, how things would turn out. The stress of not being able to talk about it with anyone.

"Yana." The old man said, causing her to snap out of her silent realm. She noticed that she was clinging onto the Doctor's hand now, his coat having been taken off, and that they had moved away from the computer where they had been looking at the signal.

The Doctor smiled at him. "Professor Yana. This new science is well beyond me, but all the same, a boost reversal circuit, in any time frame, must be a circuit which reverses the boost." He rambled, as Kari knew he would. "So, I wonder, what would happen if I did this?" He asked, using his sonic screwdriver on some device connected to a bunch of wired, and then yanking the switch on it over.

Suddenly everything powered up, much to the surprise of Professor Yana and Chantho. "Chan, it is working, tho." She said in awe, as alarms blared and sirens whirred.

"But how did you do that?" The professor asked, absolutely stunned at what the Doctor had done.

"Oh, we've been chatting away. I forget to tell you, I'm brilliant." The Doctor informed him, giving him one of the smiles that Kari loved so much.

"You're not that brilliant, Doctor." Kari whispered to him in his mind, causing him to look at her with a frown on his face. "Forget it, it doesn't matter."

He looked at her, the concern showing on his face. "Kari, is there anything you can tell me about this to give me a hint as to why you are so scared of being here?" He asked her, but not holding out much hope that he was going to get anything from her.

She wanted to shake her head at him, to keep everything all to herself like she planned. "The past is coming back to haunt us. Everything isn't as simple as you think it is, Doctor. I am not just scared, okay? I'm beyond scared, a thousand miles past terrified and several centuries further than petrified." Kari told him, trying not to give him too much, but at least enough for him to understand why she was being so quiet.

The Doctor just wrapped both his arms around her, trying to work out what else he could say to her. "What do you mean, the past is coming back to haunt us?"

"I can't tell you, for two reasons. One, you know, spoilers, and two, I haven't exactly been there yet, so I'm not entirely sure what happened." Kari admitted, having never been that far back in the Doctor's past yet, or having been to New New York with Martha.

"So how do you know?" He wondered.

Kari pulled away a little and looked up at the Doctor. "Because I know this. I've seen it. I know what happens, I always know all the bad stuff that is going to happen. And I wanted to stop it, but you and Jack wouldn't let me." She told him, trying not to get upset. She was sick of crying, of always getting upset with every small, little thing that happened. She didn't want to do that any more. "And I know, I just know, that I'm going to get blamed at some point for something that happens." She added, glancing over at Martha and Jack, both of whom were talking with the professor and his assistant.

The Doctor let out a sigh as he looked down at her. "Kari, we all promised you that no matter what happened, we would not blame you for anything. And we meant it, we really did."

She closed her eyes and shook her head at him a little. "People always break their promises. So much is going to happen, Doctor, and I don't want it to."

All he could do was hold onto her tightly, understanding how she felt and just wishing there was something he could do to help her. But he knew there wasn't. "Come on, we have work to do." He told her gently, pressing his lips against her for a few moments, before dragging her off to get started on sending everyone to Utopia.

Kari was just working in a daze, doing what she was told but paying no attention to anything else. She had completely shut herself down, and was now walking around on autopilot. Whenever the Doctor, Jack or Martha spoke to her, she just mumbled a response and carried on. It was the only way she was able to get through it all, to just ignore what she could until the moment presented itself where she could possibly change something.

It wasn't until a while later that something finally made her focus on what was going on around her. Something felt different, and when she looked around the room, she saw that blue box that she had been so desperate to get back into. "Oh, you have no idea how much I missed you." Kari whispered to the box, placing a hand on the wooden panelling. "Or how much I don't want to be here."

As if knowing exactly what she was saying, the TARDIS hummed, the vibrations being felt under Kari's hand. "We'll soon be out of here, Kari." The Doctor said, almost making her jump out of her skin as he came up behind her. "Just a little while longer." He then disappeared into the blue box, and although Kari wanted to follow him, in hopes that she would get pulled somewhere else, she knew she couldn't.

"Do you need me to do anything, Jack?" She said, looking over at her big brother who was working away himself. Kari knew she just needed to keep herself busy now, busy until her time to interfere came.

He looked over at her, and knew that nothing was right with her still. "Go check on the Doctor, make sure he doesn't need any help."

"Uh, no thanks. I'd be better off staying out here." She said, looking at him and then back at the blue box. She saw the quizzical look that her brother was giving her. "If I go in there, then there is every chance that I will not come back out again." Jack nodded at her in understanding.

A few minutes later, and the Doctor was dragging thick, heavy cables out of the TARDIS. "Extra power. Little bit of a cheat, but who's counting?" He said, dragging them across the floor. "Jack, you're in charge of the retro feeds."

"Oh, am I glad to see that thing." Martha called, finally returning with Chantho. In all honesty, Kari hadn't even noticed that they pair of them had gone anywhere.

But what she did notice was the way that Professor Yana was rubbing his head, his face showing that he was in pain as he quickly sat down. "Chan, Professor, are you all right, tho?" Chantho asked, seeing his distress as well.

"Yes, I'm fine. I'm fine." He said, waving her off. "I'm fine. Just get on with it."

Kari just watched him, a hint of fear in her eyes. "You don't have to keep working." The Doctor told him. "We can handle it." He said, thinking that the man was just getting exhausted from all the work and excitement at the prospect of leaving for Utopia.

"It's just a headache, just a noise inside my head, Doctor." The professor told him. "Constant noise inside my head."

"What sort of noise?" The Doctor asked him curiously, kneeling down in front of him and a slight look of concern on his face.

"The sound of drums." Kari said, without even realising it. Both the Doctor and Professor Yana looked over at her. "Uh, sorry."

The professor was stunned, to say the least. "How did you know?" He asked her.

"The sound of drums, more and more, getting closer and closer." She said, taking small steps towards the pair. "And you've had it all your life, right?"

He nodded at her. "Every waking hour. But… how did you know that? How could you possibly know that?"

Before Kari had the chance to say anything, the Doctor was speaking for her. "Oh, well, my Kari is rather brilliant as well. Shy and quiet at times, bold and loud at others, and I'd say she's slightly psychic."

Kari just glared at him. "You know I'm not psychic. I just know stuff that I shouldn't." She called over to him. "Anyway, there's work to be done, so better get to it." She walked away, and over towards Jack.

"How you doing, Princess?" He asked her, wrapping an arm around her and kissing the top of her head. She was getting so much attention but it wasn't making her feel any better. She didn't want the attention, she wanted it to all be over.

"I just want it all to be over Jack. Promise me that when this is all over you will take me to see everyone back in Cardiff?" She asked, trying to find a way to distract herself. "Please?"

The moment he looked at her and saw her eyes, he knew there was no way in the universe he could say no to her. "Course you can, I know they'd all love to see you. Isn't it about time we had another birthday party or something anyway?" He asked her.

"Uh, probably, yeah. It's just been a long time since I last saw everyone. I could really do with one of Ianto's coffees, and having a bit of a banter with Owen." She said, watching Jack do something with some of the equipment. She had no idea what he was doing, and she wasn't going to ask either.

Jack chuckled a little at how Kari always wanted Ianto's coffee. Sometimes he thought that was the only reason why she wanted to visit. "So, it's all for his coffee and to joke around with Owen, huh? Got nothing to do with your big brother being there?"

Kari looked up at him, and gave him a nudge with her elbow. "Shut up, Jack. You know I love seeing you, as well as everyone else. But Ianto really does make some amazing coffee, I refuse to drink anything else." She said, before going off into her own little world once more.

"Captain, keep the dials below red." Professor Yana called, causing Kari to blink several times and look at the man standing beside her. She was still standing with Jack, clinging onto his arm while he worked. Kari had never drifted into her own little world so much, especially not during an adventure.

"Where is that room?" She heard the Doctor ask, turning her head and looking over to where he was with Martha and the professor, looking at a monitor.

"It's underneath the rocket. Fix the couplings and the footprint can work. But the entire chamber is flooded with stet radiation." Professor Yana explained, as Kari finally pulled herself away from Jack and shuffled over to the Doctor.

"Stet?" The Doctor questioned, wrapping an arm around Kari the moment she was in his reach. "Never heard of it."

The professor looked at the pair, a small smile on his face. "You wouldn't want to. But it's safe enough, if we can hold the radiation back from here." He said, all of them watching the man on the monitor entering the room full of radiation. Kari was holding her breath as he started to connect everything together. "It's rising. Nought point two. Keep it level!" He called, looking over at Jack.

"Yes, sir!" Jack replied, Chantho working alongside him now that Kari wasn't beside him.

All of a sudden, alarms starting blaring as the lights flickered. "Chan, we're losing power, tho." Chanto announced, panicking a little.

The Doctor just tightened his grip on Kari's hand. As Jack rushed around to try and stabilise everything. "Radiation's rising!" The Doctor called over to him.

"We've lost control." Jack cried back to him, knowing that they needed to figure it out and do something soon. Professor Yana reminded them that the chamber was going to flood with radiation if they didn't do anything.

"Jack, override the vents!" The Doctor shouted at him, finally letting go of Kari and dashing around himself, working to get it done. Kari just stood there with Martha, feeling rather useless during the crisis.

Kari watched as her brother grabbed hold of two rather large, and rather dangerous looking cables. "We can jump start the override." He said, holding onto them tightly.

"Don't!" The Doctor cried at him. "It's going to flare!" But Jack didn't listen to him, he held the ends of the cables, sending the electricity surging through him as he held them together.

Martha was quick to rush over to him, but Kari managed to reach him first as he hit the ground. "Chan, don't touch the cables, tho." Chantho warned her, kicking them carefully out of the way.

"Oh, I'm so sorry." The professor said, looking down at Kari and how she was cradling Jack's head in her lap. Only Kari really didn't seem as upset as he was, nor Martha who was getting ready to give him CPR.

"The chamber's flooded with radiation, yes?" The Doctor said, leaving Kari alone with Jack and not worrying about how she was staying on the floor with him. He knew that she was just waiting for him, for him to come back to her. Even when Martha started to give him mouth to mouth, she didn't move.

"Without the couplings, the engines will never start. It was all for nothing." Professor Yana told him, all of the hope he had now completely gone. All the work he had put into the project, all the time and the hope he had gathered. Everything they had accomplished since the Doctor arrived had all be pointless.

"Oh, I don't know." The Doctor said, before taking a step forward and tugging at Martha's arm. "Martha, leave him."

The woman looked at him with total confusion in her eyes. "You've got to let me try." She protested. She knew something was wrong with Kari and she wasn't about to just stand there and not help her friend's brother.

Come on, come on, just listen to me. Now leave him alone." The Doctor said, finally managing to tug her away from the body lying on the ground. He looked at Kari and she gave him a small nod that he only just managed to catch. "It strikes me, Professor, you've got a room which no man can enter without dying. Is that correct?" He asked, watching as Kari watched Jack.

The professor looked at him and nodded. "Yes."

"Well…" The Doctor said, drawing it out. A moment later, Jack gasped, snapping his eyes open and bolting upright. "I think I've got just the man." It was clear that the Doctor had planned to be a little dramatic at that point.

Jack just looked at everyone who was staring at him. "Was someone kissing me?" He asked, before getting a whack around the back of the head from Kari. "Hey, what was that for?"

"Don't keep doing that." She whispered. "It scares the hell out of me when you do that. What if one day you don't come back, Jack? What if one day, you die and don't come back? What do I do then?" It was something she had thought about, even though she knew what would happen to him eventually, but it didn't stop her imagination from working overtime.

He noticed that she was deadly serious and that tears were glistening in her eyes. "Hey, come on, Princess. You know I'm not going to leave you any time soon." Jack assured her, giving her a tight hug.

"Yeah, you better not, Jack." Kari told him, her voice still in a whisper. "Anyway, while you were dead, the Doctor had an idea." She added, knowing what was coming next.

She had managed to get through everything so far, but she knew that the worse was still to come. And she knew what she had to do, who she had to stay with and keep an eye on. She wasn't scared of Professor Yana, the old man who had worked so hard to send everyone to Utopia. Kari was scared of the man he really was, and how much he knew about her.
