A/N: What are you waiting for? Time to start reading!

I do not own Doctor Who. All I own is my OC Katy and this story. Please review and no flaming will be tolerated. Thanks :)

DESTINATION: UNKNOWN

"Come with me, we can go
To a paradise of love and joy
A destination unknown!"
– Alex Gaudino: 'Destination Calabria' (Destination Calabria [2003])

Silo gates

A water supply truck drives through the gates, watched by the Futurekind tribe.

"All troops report to silo. I repeat, all troops report to silo." Atillo orders. The guards manning the electric gates, start heading inside.

"Inside! Everyone, inside!" shouts the head guard. "Come on, move, move, move!"

Corridor

Martha and Chantho weave their way through the crowds of refugees making their way towards the rocket ship, with Martha supporting a still weakened Katy with an arm around her waist. The medical student was reluctant at first to bring Katy along with them, but Katy was insistent, as she was getting bored with sitting around and doing nothing while her friends and boyfriend were picking up the slack, helping these refugees get on their way towards Utopia. They pass by Creet, who was heading towards the ship himself, no sign of any clipboard in his possession.

"Excuse me," Martha flags him down and Creet turns and acknowledges her politely. "Hey, what was your name? Creet?" She asks him, and he smiles and nodded at her.

"That's right, miss."

"Who are you with, Creet? You got family?" Martha questioned.

Creet shook his head.

"No, miss. There's just me." He responded, nonchalantly. Martha looked a little saddened by this.

"Oh, well. Good luck. What do you think it's going to be like in Utopia?"

"My mum used to say the skies are made of diamonds," Creet responded, grinning from ear to ear, and looking positively excited by the idea. Katy chuckled at the boy's enthusiasm.

"Sounds lovely." She commented.

"Yeah, good for her." Martha agreed. "Go on, off you go. Get your seat." Creet nodded and waved at them both before becoming just another face in the crowd. The two girls continue on their way with Chantho, unaware that they were being watched by one of the Futurekind.

Yana's Laboratory

A curious smell reaches the Doctor's nose, and he leans down and sniffs one of the wires. His eyebrows rose when he realised exactly what he was smelling.

"Is this…?"

"Yes, gluten extract." Yana had already interpreted what the Doctor was about to ask and gives him a small acknowledging smile. "Binds the neutralino map together."

"But that's food," the Doctor was amazed. "You've built this system out of food and string and staples?" He lets out an impressed chuckle. "Professor Yana, you're a genius."

"Says the man who made it work," Yana retorts.

"Oh, it's easy coming in at the end, but you're stellar!" The Doctor insisted. "This is, this is magnificent. And I don't often say that because, well, because of me."

"Well, even my title is an affectation," Yana admitted. "There hasn't been such a thing as a university for over a thousand years. I've spent my life going from one refugee ship to another."

"If you'd have been born in a different time, you'd be revered. I mean it. Throughout the galaxies," The Doctor stated, brightly.

Yana snorted, unhappily.

"Oh, those damned galaxies. They had to go and collapse. Some admiration would have been nice. Yes, just a little, just once." He sighed heavily. The Doctor looks at him with the genuine admiration Yana had been talking about.

"Well, you've got it now. But that footprint engine thing. You can't activate it from onboard. It's got to be from here. You're staying behind," He realises.

"With Chantho. She won't leave without me. Simply refuses," Yana stated, a little exasperatedly.

"You'd give your life so they could fly."

"Oh," Yana chuckles scornfully. "I think I'm a little too old for Utopia." He states, truthfully. "Time I had some sleep."

"Professor," Atillo's voice comes over the intercom. "Tell the Doctor we've found his blue box." He requests, and the Doctor lights up with relief.

"Ah!"

"Doctor?" Jack comments, and both look on the monitor at the image of the Tardis being wheeled into the silo by the water supply truck. The Doctor grinned triumphantly at Yana, who comes over to see what the commotion was on the monitor for himself.

"Professor, it's a wild stab in the dark, but I may have just found you a way out." The Doctor confirms, and walks off, not noticing the trance-like state Yana appeared to be in as the older man stares at the image of the Tardis on the monitor.

A couple minutes later, the Tardis is in the laboratory and the Doctor is dragging a power cable out of it.

"Extra power. Little bit of a cheat, but who's counting?" the Doctor mutters out loud, before shouting over to Jack, who was assisting him with the cables. "Jack, you're in charge of the retro feeds." Martha, Katy, and Chantho return from their errand, and both of the Doctor's companions sag with relief when they see the sentient ship, back safe and sound in their presence.

"Oh, am I glad to see that thing." Martha commented out loud. Katy walks over to the Tardis and lays a hand on the side of the ship, leaning in to press her forehead against her in comfort.

"We would be lost without her…" Katy added and was about to walk away when the Tardis suddenly speaks to her telepathically.

"It's almost time…" She whispers to Katy, who freezes and looks back at the ship in surprise.

"Excuse me?" Katy whispers back, looking around for the Doctor to see if he was nearby. He was, but he hadn't even looked up when the Tardis had spoken out, which meant that whatever she had to say was only for Katy's ears. "Almost time for what?" She murmured.

"Almost time to open your locket, dear one…" the Tardis elaborates, and Katy's eyes widen comically as she looks down at the locket around her neck and carefully picks it up.

"When?" Katy asks urgently, both excited and dreading the moment.

"You will know when the time is right, Katy…" the Tardis promises before falling silent once more. Katy scowls at that answer, but before she could demand the Tardis to be a bit more specific, Chantho suddenly speaks up, sounding concerned.

"Chan-Professor, are you alright-tho?"

"Yes, I'm fine. I'm fine. I'm fine." Yana snaps, sounding irritated. "Just get on with it." He requested.

However, Chantho didn't look entirely convinced.

"Connect those circuits into the spar, same as that last lot. But quicker!" Jack instructs Martha, catching Katy's attention. Martha makes a face at Jack's bossy comment.

"Ooh, yes, sir." She responded, mockingly. Katy goes over to Jack to lend assistance somewhere.

"May I help, Jack?" Katy asks.

"Nah, we've got it, hon. But thanks anyway." Jack smiles warmly at Katy. "Go take a load off, you still don't look particularly well." He suggests.

Katy glances over at Yana, with a frown.

"I don't appear to be the only one…" She observes, going over to sit down like she was told to, as the Doctor seemed to agree with Katy's comment, going over to Yana with mild concern on his face.

"You don't have to keep working. We can handle it," the Doctor pointed out, and once again Yana looks annoyed about being fussed over.

"It's just a headache," Yana stated which grabs both the Doctor and Katy's attention. "It's just, just noise inside my head, Doctor. Constant noise inside my head…" He complained half-heartedly.

"What sort of noise?" Katy pipes up from where she was sitting. Yana and the Doctor look over to her.

"It's the sound of drums. More and more, as though it's getting closer." Yana clarifies, and Katy looks slightly disturbed.

"That's funny, the thudding pain in my head sort of reminds me of drumbeats too…" Katy mutters. "It's an odd coincidence."

"When did it start?" the Doctor frowned.

"Oh, I've had it all my life. Every waking hour…" Yana stated, before dismissing it. "Still, no rest for the wicked." He goes back to work, and the Doctor walks over to Katy and squats down in front of her, looking thoughtful.

"Should we be worried about this, Doctor?" Katy asked, quietly.

But he shook his head.

"Nah, I don't think so. It's like you said before, an odd coincidence." He reassures her, and Katy gives him a sceptical look.

"That's what you said before about the words 'Bad Wolf' following us around and look what happened then." Katy points out, and the Doctor grimaces when he remembers dismissing Margaret the Slitheen choosing the Welsh translation of Bad Wolf; Blaidd Drwg, to name her Nuclear Power Plant project, as something not worthy of focusing on. He wasn't about to make the same mistake again.

"Just keep a sharp eye out…" the Doctor suggests, and Katy nodded in agreement.

Martha helps Chantho put some circuit boards back onto a rack. She observes Chantho occasionally looking over at Yana with a mingled look of both concern and fondness and grinned at her.

"How long have you been with the Professor?" Martha asks Chantho, who smiles shyly.

"Chan-seventeen years-tho." She replied. Martha's eyes widen in surprise.

"Blimey. A long time."

"Chan-I adore him-tho." Chantho admits, and Martha looks at her sympathetically, already interpreting how her next question was likely to be answered with.

"Oh right, and he—"

"Chan-I don't think he even notices-tho." Chantho looks a little upset, but at the same time used to it.

"That's sucks," Martha comments, sympathetically.

"Chan-but I'm happy to serve-tho." Chantho reassures her. Martha studies Chantho curiously.

"Do you mind if I ask? Do you have to start every sentence with 'chan'?"

"Chan-yes-tho." Chantho nodded.

"And end every sentence with—"

"Chan-tho-tho."

"What would happen if you didn't?" Martha asks slyly and Chantho immediately looked horrified by the suggestion.

"Chan-that would be rude-tho." She explained, looking scandalised. Martha raises an eyebrow, looking amused.

"What, like swearing?"

"Chan-indeed-tho." Chantho nodded, vehemently. Martha grinned, mischievously.

"Go on, just once."

"Chan-I can't-tho." Chantho looked hesitant.

"Oh, do it for me." Martha wheedles, giving the blue alien a puppy-dog stare. Chantho glances about, as though looking for someone who was likely to chastise her for breaking the rules of her people and smirks playfully at Martha.

"No." Chantho complies and bursts into giggles, emboldened by her one act of rebellion, just this once.

"Professor!" They look over at the monitor where Atillo's voice rings out of, trying to get signal on the screen, which was still blank, and playing up like an old television on the fritz. "Systems are down. Professor, are you getting me?" Atillo calls out, somewhat impatiently. Yana goes over to the monitor and presses the spacebar, temporarily activating the temperamental monitor.

"I'm here! We're ready!" Yana confirms. "Now all you need to do is connect the couplings, then we can launch." He instructs, then groans in frustration when Atillo's face disappears from the monitor. "God sake! This equipment. Needs rebooting all the time!"

"May I help?" Katy inquires, still trying to be helpful despite her headache, that she apparently shared with Yana. He glances over at her and smiles appreciatively.

"Yes, if you could." Katy gets up from her seat and comes over to the monitor, taking a seat on the chair in front of it. "Just press the reboot key every time the picture goes."

"No problem," Katy nodded.

"Good!" Yana thanks Katy as she presses down on the spacebar. Atillo's face returns on screen.

"Are you still there?" Atillo asks, impatiently. Yana jumps like he was a misbehaving child and was being scolded by his mum.

"Ah, present and correct. Send your man inside." He instructs. "We'll keep the levels down from here."

"He's inside," Atillo confirms a few minutes later. "And good luck to him."

"That's in no way ominous…" Katy commented, grimly. Yana ignores the comment and turns towards Jack.

"Captain, keep the dials below the red." He instructs Jack, who nods and turns a dial to keep the levels steady. The Doctor gestures towards the monitor.

"Where is that room?" He asks.

"It's underneath the rocket," Yana explains. "Fix the couplings and the footprint can work. But the entire chamber is flooded with stet radiation."

"What's stet radiation?" Katy questioned.

"No idea. I've never heard of it." The Doctor shrugged, looking at Yana for an interpretation as the older man made a face.

"You wouldn't want to. But it's safe enough, if we can hold the radiation back from here." He explains. All of them watch the monitor showing the man connecting the equipment. Suddenly, an alarm sounds. "It's rising. Naught point two. Keep it level!" He warns Jack.

"Yes, sir!" Jack complies. The second connection is made. However, the electricity suddenly starts fading.

"Chan-we're losing power-tho!" Chantho announces.

"Radiation's rising!" the Doctor warns.

"We've lost control!" Jack yells.

"The chamber's going to flood!" Yana starts to panic.

"Jack, override the vents!" the Doctor instructs Jack. The ex-Time Agent immediately pulls out two power cables, alarming the Doctor when he realises what his friend was about to do.

"We can jump start the override," Jack suggests and proceeds to hold the two live ends of the cables together.

"Don't! It's going to flare!" the Doctor shouts. But he is too late, Jack is electrocuted.

"JACK!" Katy squeals in fear, as Jack's dead body crumples to the ground. The Doctor groans in frustration.

"I've got him!" Martha goes to aid Jack and flips him on to his back, preparing to perform mouth-to-mouth resuscitation on him.

"Chan-don't touch the cables-tho." Chantho cautions Martha. Yana looks saddened by Jack's death.

"Oh, I'm so sorry." He gives his condolences. However, the Doctor doesn't look concerned, much to Katy's ire. Did he not care that his friend had literally died before his eyes? She was about to give him a piece of her mind, when the Doctor goes over and places a finger against her lips, silencing her.

"The chamber's flooded with radiation, yes?" the Doctor questioned casually, perching on the side of the table Katy was sitting in front of, manning the monitor for Yana. Martha continues giving Jack mouth-to-mouth resuscitation.

"Without the couplings, the engines will never start. It was all for nothing," Yana despaired. The Doctor gets up from the table and goes over to Martha.

"Oh, I don't know." He responded light-heartedly, before gently reaching down and stopping Martha, pulling her to her feet and away from Jack. "Martha, leave him…" the Doctor stated firmly.

"You've got to let me try…" Martha protests, looking at him with confusion.

"Come on, come on, just listen to me. Now leave him alone," He insists, and Martha reluctantly steps back from Jack's lifeless body. "It strikes me, Professor, you've got a room which no man can enter without dying. Is that correct?" the Doctor enquires, and Yana looks at him oddly.

"Yes?"

"Well…" the Doctor trails off, just as Jack miraculously gasps back to life, stunning them all. "…I think I've just got the man."

"Was someone kissing me?" Jack looked confused.

"What the hell just happened?" Katy demanded, completely baffled.

Control Room

Since time was of the essence, the Doctor and Jack sprinted as fast as their feet could carry them towards the control room. Once they get there, Jack wastes no time and starts removing his trench coat and button up shirt in preparation to get inside the radiation chamber. The Doctor explains the situation to Atillo, who was watching all this with a bemused expression on his face.

"Lieutenant, get on board the rocket! I promise you're going to fly!" The Doctor stated confidently.

"But the chamber's flooded…" Atillo objects.

"Trust me. We've found a way of tripping the system." The Doctor stated before shoving him in the direction of the rocket. "Run!" The Doctor turns and looks at Jack strangely when he sees that he had been taking off his clothes this whole time. "What are you taking your clothes off for?"

"I'm going in," Jack clarified, and the Doctor takes a brief look at the radiation room.

"Well, by the looks of it, I'd say the stat radiation doesn't affect clothing, only flesh." The Doctor pointed out, but Jack only shrugged.

"Well, I look good though." He goes to head inside the chamber but pauses and puts to the Doctor a question that he had been curious about ever since he had clapped eyes on the Time Lord again. "How long have you known?"

"Ever since I ran away from you," the Doctor admitted before gesturing towards the radiation chamber. "Good luck." Jack nods briefly before sliding the heavy metal door open and heading inside; immediately continuing to connect things up to the waiting rocket as the Doctor slides the door closed behind him.

Yana's Laboratory

Katy reboots the monitor by typing Atillo into a hiragana keyboard. It responds, but only shows static on screen. She groans in frustration, on top of the headache pain that only seemed to gradually get worse over time, no matter how much water she consumed to keep herself as hydrated as possible.

"Ugh, we lost picture when that thing flared up," Katy grumbles to Martha who was hovering nearby. "Doctor? Are you there?" She calls out.

"Receiving, yeah." He confirms. "He's inside."

"And still alive?" Martha was shocked.

"Oh, yes."

"But he should evaporate," Yana pipes up; amazed. "What sort of man is he?" He wondered out loud.

"Jack's most definitely human, I can vouch for that." Katy confirmed, with a small smile. "Still not entirely sure what's going on though. The Doctor's obviously not telling us something, and it's probably very important too." She grouses a little.

"And I've only just met him," Martha explains to Yana. "The Doctor sort of travels through time and space and picks people up. God, I make us sound like stray dogs." She shrugs. "Maybe we are."

"Yeah, I can be a bit of a bitch sometimes…" Katy jokes, smirking playfully at Martha who gives Katy a flat expression because of her joke.

"Ha, ha. I'm haemorrhaging inside, it's so funny…" She drawls, earning a giggle from the younger girl. "You must be feeling better if you can joke like this."

"Not really. But it's a nice distraction." Katy admits, wincing a little.

"He travels in time?" Yana mumbles, looking a bit distant. However, neither Katy or Martha notice this.

"Don't ask me to explain it," Martha begged. "That's a Tardis, that box thing." She points towards the Blue Box standing against the wall. "The sports car of time travel, he says."

"I don't think she'd particularly like you calling her that…" Katy wrinkles her nose, and Martha blinks at her in surprise.

"It's a she?"

"Yep. She told me so herself. All Tardises were apparently female when they were first grown," Katy explained. "I read about it in one of the books in her library…" Katy explained. Martha was about to question Katy further on her knowledge when:

"When did you first realise?" Both Katy and Martha glance quickly at the monitor when they hear the Doctor chatting to Jack inside the radiation chamber.

Radiation Chamber

Jack struggled a little, sweating and straining to turn the handle he was working on. He looked up at the Doctor and hesitated before eventually responding to his question.

"Earth, 1892." Jack confirmed. "Got in a fight in Ellis Island." Both Katy and Martha back in Yana's laboratory frowned in confusion. "A man shot me through the heart." Katy's eyes widened in horror. "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."

"Ooh!" the Doctor winced, sympathetically.

"In the end, I got the message: I'm the man who can never die." He narrowed his eyes at the Doctor, slightly accusingly. "And all that time you knew."

"That's why I left you behind," the Doctor confessed with a shrug. "It's not easy even just looking at you, Jack, because you're wrong."

"Thanks," Jack made a face.

"You are," the Doctor stated defensively. "I can't 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." Jack grinned at his friend.

"So what you're saying is that you're, er, prejudiced?"

"I never thought of it like that." The Doctor admitted, thoughtfully.

"Shame on you," Jack playfully scolded in between laughs.

"Yeah," the Doctor reacted shamelessly.

"Last thing I remember, back when I was mortal, I was facing three Daleks. Death by extermination. And then I came back to life." Jack looked at the Doctor with a serious look on his face. "What happened?" The Doctor hesitated, looking over at the monitor, knowing that Katy was most likely listening in to this conversation. But knew that she was bound to learn about this anyway, so decided to just wing it.

"Katy." He replied succinctly, and both Jack and Katy were shocked.

'What did I do?' Katy was horrified. Why couldn't she remember any of this? Martha looks at her questioningly, but Katy chooses to ignore her in favour of learning more.

"I thought you'd sent her back home with Rose?" Jack was confused. The Doctor frowned; his memories of that moment in time rushing back to him, as well as how he felt when he realised what Rose's intentions could have done to the Tardis, had Katy not intervened when she did. Which essentially was the reason why Jack was now immortal.

"They came back. Rose had opened the heart of the Tardis, and Katy managed to stop her from absorbing the time vortex itself." He lets out an angry huff. "Unfortunately, in order to do so, Katy was forced to absorb the time vortex herself." Anguished tears were streaming down Katy's face, but unknown to her and Martha, tears were also streaming down Yana's face, but for different reasons.

"What does that mean exactly?" Jack questioned.

"No one's ever meant to have that power. If a Time Lord did that, he'd become a god. A vengeful god." The Doctor explained.

"So why didn't that happen to—" Jack was referring to Katy and her status as a Time Lady.

"Because she hasn't awakened just yet," the Doctor confirmed. "But everything she did was so human. She brought you back to life, but she couldn't control it, and she brought you back forever." The Doctor then looked somewhat intrigued. "That's something, I suppose. The final act of the Time War was life."

"Do you think she could change me back?" Jack wondered. But the Doctor shook his head, looking regretfully at him.

"I took the power out of her." Jack nodded, looking slightly disappointed. There was silence for a few moments.

"I went back to the Estate, in the nineties, just once or twice." Jack explained. "Rose," he clarified when he saw the questioning look on the Doctor's face. "Watched her and Katy growing up, but never said hello. Not even to Katy. Timelines and all that."

"Do you want to die?" the Doctor asked, curiously.

"Oh, this one's a little stuck…" Jack refers to the mechanism he was fiddling with and evaded the question. But the Doctor persisted.

"Jack…" He looked at him, slyly. Jack immediately caved.

"I thought I did. I don't know," He admitted. "But this lot," Jack referred to the humans they were currently attempting to send to Utopia. "You see them out here surviving, and that's fantastic."

The Doctor grinned at him.

"You might be out there, somewhere." The Doctor points out.

"I could go meet myself," Jack realised half-heartedly.

"Well, the only man you're ever going to be happy with," the Doctor smirks at him, and Jack grins back, enjoying the banter he was sharing with this version of the Doctor.

"This new regeneration, it's kind of cheeky." Jack observed, chuckling a little.

Yana's Laboratory

Katy was devastated.

She was responsible for Jack's state of immortality. Out of shame, she turns away from the monitor and stares at the floor, upset. Martha shakes her head, oblivious to Katy's despair.

"I never understand half the things he says—What's wrong?" She notices a tearful Yana and immediately goes over to find out what the matter was.

"Chan-Professor, what is it-tho?" Chantho was equally as concerned.

"Time travel!" Yana was distraught. "They say there was time travel back in the old days. I never believed." Then he turns scornful. "But what would I know? Stupid old man. Never could keep time. Always late, always lost. Even this thing never worked…" Yana pulls out a fob watch from within his waistcoat pocket and shows to Martha and Chantho. Martha's eyes widened when she sees the fob watch.

It definitely looked familiar … uncomfortably so.

"Can I have a look at that?" Martha asks, a little timidly. She was hoping and praying that she was so very wrong about what she was suspecting. Yana frowned dismissively.

"Oh, it's only an old relic. Like me." He said, but Martha was insistent.

"Where did you get it?" She asked, cautiously.

"Hmm?" Yana blinks at her in confusion, before frowning reminiscently. "I was found with it." Katy's head immediately snaps over in his direction when she hears those familiar words; words that she too had once used when people had asked her about her locket's origins. She then looks down at the fob watch in Yana's hand, and her eyes widened too at the impossible item.

'No … he couldn't be…' She gets up from the seat in front of the monitor and slowly comes over to where the three of them were standing in a circle.

"What do you mean?" Martha asked.

"An orphan in the storm. I was a naked child found on the coast of the Silver Devastation. Abandoned, with only this," Yana explained.

"Have you opened it?" Katy suddenly blurted out, startling Martha who looks at her quizzically. But Katy ignores her, determined to discover the truth that she and the Doctor might not be the only ones that survived Gallifrey's destruction. Yana gives her a weird look.

"Why would I? It's broken."

"How do you know it's broken if you've never opened it?" Martha pointed out. Yana looked perplexed by their questions.

"It's stuck. It's old. It's not meant to be. I don't know," He sounded slightly hysterical. Slowly, Martha reaches out and flips over the watch, flinching back like the watch had burned her when she recognises the inscriptions. Katy pales dramatically. 'Oh, my God!'

"Does it matter?" Yana looks at both girls suspiciously.

Immediately, Martha pastes on an unconvincing nonchalant face. But Katy, continues staring at the fob watch, like it was a lethal snake; poised to strike. She barely registers her headache pounding that same drumbeat in her head as she reaches up and grabs her locket in her clenched fist, seeking comfort from it.

"No. It's nothing," Martha reassures him. "Listen, everything's fine up here. I'm going to see if the Doctor needs me." She turns towards Katy and looks meaningfully at her. "I'll be right back, Katy."

Martha bolts from the room.

Control Room

"Yes!" Jack makes the final connection with a triumphant yell and immediately hi-tails it out of the radiation chamber. The Doctor reaches for a nearby phone that was connected to the rocket transporting the surviving refugees to Utopia.

"Lieutenant, everyone on board?" the Doctor asks.

"Ready and waiting," Atillo confirms.

"Stand by. Two minutes to ignition." The Doctor tells him before promptly hanging up on him.

"Ready to launch. Outer doors sealed." Atillo gives the overhead announcement to those passengers on board the spacecraft.

'Countdown commencing. T-minus ninety nine, ninety-eight…' the computer starts counting down to ignition as Jack and the Doctor race around, flicking on switches. Martha runs in, breathless and looking extremely concerned about her discovery back in Yana's laboratory.

"Ah, nearly there!" the Doctor declares. "The footprint, it's a gravity pulse. It stamps down, the rocket shoots up. Bit primitive," He shrugs. "It'll take the both of us to keep it stable." He tells Jack.

Martha goes over to him.

"Doctor, it's the Professor. He's got this watch. He's got a fob watch." The Doctor snaps his head at her, looking shocked. "It's the same as yours. Same writing on it, same everything." She tells him, urgently.

"Don't be ridiculous," the Doctor chides her, but Martha couldn't help but notice the hopeful expression on his face.

"I asked him. He said he's had it his whole life."

"So he's got the same watch…" Jack commented, not understanding the seriousness of the situation.

"Yeah, but it's not a watch. It's this chameleon thing—"

"No, no, no, it's this, this thing, this device, it rewrites biology." The Doctor cuts off Martha, looking rather agitated. "Changes a Time Lord into a human."

"And it's the same watch," Martha insists, firmly.

"It can't be…" the Doctor breathed, looking doubtfully at her. An alarm sounds, prompting the Doctor to fix whatever it was alerting. Jack immediately looks excited on the Doctor's behalf.

"That means he could be a Time Lord," Jack exclaimed. "You and Katy might not be the only ones." The Doctor notices something out the corner of his eye and immediately barks at Jack.

"Jack, keep it level!" He instructs, and Jack immediately goes and fixes the issue. Martha attempts to see this as a positive thing.

"But that's brilliant, isn't it?"

"Yes, it is. 'Course it is." The Doctor agreed. "Depends which one. Brilliant, fantastic, yeah." But there was something that still persisted with him. "But they died, the Time Lords. All of them. They died."

"Not if he was human," Jack points out. The Doctor turns and looks at Martha, urgently.

"What did he say, Martha? What did he say?" He asked.

"He looked at the watch like he could hardly see it. Like that perception filter thing." Martha responded, reluctantly, realising that Katy and she had possibly done the wrong thing by asking Yana questions about the fob watch.

"What about now? Can he see it now?" the Doctor asked, worriedly.

Yana's Laboratory

Katy watched Yana nervously, as he continues to stare at his fob watch like a man possessed. Part of her was overjoyed that she and the Doctor had managed to find yet another Time Lord that had escaped the destruction of Gallifrey. But at the same time, which Time Lord was he?

For all she knew, this man was likely to have been banished for something or wasn't a very nice person at all or would recognise her as a Time Lady he despised for things that she obviously would not remember at this precise moment. She seriously hoped that the Doctor would arrive soon to help them figure out what to do next.

"Chan-Yana, won't you please take some rest-tho?" Chantho urged Yana, who continued to ignore his assistant and Katy, still obsessively staring at the watch.

Control Room

The computer continues counting down the minutes until the rocket would lift off and transport the refugees to Utopia. However, the Doctor was still reeling over the fact that he and Katy may not be the only survivors left.

'Thirteen, twelve, eleven, ten, nine…'

"If he escaped the Time War then it's the perfect place to hide. The end of the Universe." Jack points out.

'Six, five…' Then Martha suddenly recalls a conversation from long ago, that she kicked herself for not remembering until now.

"Wait, Doctor. Think of what the Face of Boe said," She reminded him; missing the slightly startled expression that Jack threw her when the name 'The Face of Boe' came up. "His dying words…" Jack frowned and refocused on the current situation, promising himself to revisit this 'Face of Boe' information later on. "He said…" The Doctor's eyes widened in shock as he thought back to New New York when he, Katy, and Martha had last seen the Face of Boe.

'One.' The Doctor turns the last switch and the rocket engines fire.

"You are not alone…" The Doctor could clearly hear the giant face's voice inside his head.

He glances at the monitor, at the name blinking back at him in big capital letters: YANA. Momentarily brushing aside this new discovery, the Doctor grabs the phone and shouts into it.

"Lieutenant, have you done it? Did you get velocity? Have you done it?" The Doctor asks, somewhat impatiently. "Lieutenant, have you done it?" He repeats himself. "Affirmative," Atillo replies back. "We'll see you in Utopia." The Doctor sags with relief.

"Good luck!" He bids them before hanging up the phone and gesturing for both Jack and Martha to follow him, quickly. They had a Time Lord to prevent from waking up back in the laboratory. The Doctor just hoped that they weren't too late. But then he almost stumbled in horrified realisation when he remembers … Katy was still there, weakened by a strange headache, vulnerable, and in the same room as the mysterious unknown Time Lord.

"Oh, no…" He curses underneath his breath and runs faster.

Yana's laboratory

It all happened within a split second. Katy watched as before her eyes; Yana went from a kind, mild-mannered, if overworked University professor, to someone who radiated danger and malice from every pore in his body. They say that the eyes are the window to the soul. But Katy knew instinctively, this Time Lord, whoever he was, was the epitome of evil; as his blue eyes had gone icy and flinty.

"Sir? Are you okay?" Katy asked, cautiously.

The currently unnamed Time Lord swiveled his eyes to look over at Katy, and his eyes softened a little; genuinely curious about this young girl before him. However, Katy immediately buckled over when a sharp, piercing pain suddenly ricocheted through her brain, adding on to the headache already there. She yelled and sank to her knees, clutching at her head.

"Katy!?" She, the Time Lord, and Chantho hear the Doctor's worried call off in the distance. Immediately, the Time Lord moves towards a nearby lever and activates it. The door to the control room slams shut in the Doctor's face.

"No, what are you doing?" Katy groaned in pain when she sees what he had just done.

"Chan-but you've locked them in-tho." Chantho was confused.

"Get it open! Get it open!" They could hear the Doctor's anxious voice shouting from behind the closed door, most likely at Jack.

"Not to worry, my dears. As one door closes, another must open..." The Time Lord's silky, refined voice reassures them, before he turns off the silo's defences.

"Chan-you must stop-tho." Chantho insists, alarmed. "Chan-but you've lowered the defences. The Futurekind will get in-tho." The Doctor and Jack finally manage to get the control room door open, and then they and Martha sprint for the laboratory. Katy looks over and freezes when she sees what Chantho was going to do.

"No, Chantho. This isn't the way…" She protests weakly. But the blue bug-alien ignored her.

"Chan-Professor, I'm so sorry, but I must stop you. You're destroying all our work-tho." The unnamed Time Lord looks over and sees that Chantho is pointing a small handgun at him, looking determined. But instead of looking nervous or worried, he smirks.

"Oh. Now I can say I was provoked." The Time Lord picks up a live energy cable, and glowers at Chantho as he advances towards her. Katy sees that she is in danger and attempts to get to her feet.

"No, leave her alone!"

"Now, now. Stay right where you are, my dear. I'll deal with you in a moment…" the Time Lord promises Katy without looking over at her. "Did you never think, all those years standing beside me, to ask about that watch?" He seethes at Chantho who backs off slowly. "Did you never once think, not ever, that you could set me free?"

"Chan-I'm sorry-tho." Chantho whimpers. "Chan-I'm so sorry."

"You, with your chan and your tho driving me insane…" He continued, menacingly.

"Chan-Professor, please." Chantho begged.

"That is not my name!" the Time Lord snarls. "The Professor was an invention. So perfect a disguise that I forgot who I am."

"Then who are you?" Katy demanded, from where she was, watching this weakly. The Time Lord smirks once again.

"I am the Master," He names himself, before thrusting the live end of the wire at Chantho.

"NO!" Katy shouts, in anguish. Chantho collapses to the ground before the newly named Master drops the live wire and turns towards the jar containing the Doctor's severed hand in it, caressing it. "Get away from that!" Katy hisses, drawing the Master's attention towards her.

"Ah, I almost forgot you. Now what to do?" He muses thoughtfully. However, both he and Katy snap their heads towards the laboratory doors when they hear the Doctor hammering against it.

"Professor! Professor, let me in! Let me in!" The Doctor begged.

"Doctor! Doctor, hurry!" Katy wails, much to the Master's annoyance, as he comes over to attempt to shut her up with a hand over her mouth. However, the Doctor heard his girlfriend's frightened wails.

"Jack, get the door open now!" He growls. The Doctor attempts to try again to appeal with the Master. "Professor! Professor, where are you?! Professor! Professor, are you there? Please, I need to explain. Whatever you do, don't open that watch."

During the Doctor's repetitive begging, the Master had managed to pull a struggling Katy to her feet and dragged her over to a nearby chair and tied and gagged her to it. He then removes a circuit board from the gravitational field navigation system.

"Utopia," the Master sneers, sarcastically.

"They're coming!" Katy hears Martha alerting both the Doctor and Jack and makes an attempt to free herself from the chair, while the Master disconnects the power cable from the Tardis, who groans unhappily.

"Professor!" the Doctor shouts desperately. "Open the door, please! I'm begging you, Professor. Please, listen to me!" Lying on the ground where the Master had left her, Chantho weakly raises her head and reaches for her gun while the Master's back was turned. "Just open the door, please!" the Doctor continues. Katy's head snaps up when she hears Chantho's gun fire and sees that the blue alien had shot the Master point blank before dying. Jack smashes the control panel, allowing the door to open, and the Doctor, Martha and Jack barrel through.

"DOCTOR!" Katy's muffled voice shouts through her gag to her boyfriend who ignores her momentarily to focus on the Master, who steps back into the Tardis, carrying the jar containing the Doctor's hand and shuts the door in his face.

Martha spots Chantho and goes over to her side to check her pulse.

"Let me in. Let me in!" the Doctor hammers on the Tardis doors when he realises that the Master had deadlocked the doors to prevent him from following his fellow Time Lord inside.

"She's dead," Martha refers to Chantho, before spotting a tied up and gagged Katy and her eyes widen in shock. "Katy!" She rushes over and unties her. "Are you alright?"

"No, I'm not!" Katy retorted, angrily. Jack is struggling to hold the door closed on the Futurekind.

"I broke the lock. Give me a hand!" He shouts over at both girls, and Martha immediately goes over to help him, while Katy goes over to the Doctor's side; knowing that she might be able to assist him wrangling the Master.

"I'm begging you. Everything's changed! It's only the three of us! We're the only ones left! Just let me in!" the Doctor pleaded. Then both Katy and he freeze when the familiar golden glow of regeneration shines through the Tardis window.

"Oh, God. He's regenerating…" Katy muttered, in horror.

"Doctor! You'd better think of something!" Jack urges frantically over at the door where he and Martha were still having a tug-of-war session with the ravenous Futurekind. Suddenly, evil laughter sounds over the Tardis's loudspeakers.

"Now then, Doctor—ooh, new voice. Hello, hello…" a younger male's voice is heard, sounding amazed by the sound of his new voice. "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!"

"Hold on. I know that voice…" Martha pipes up.

The Doctor ignores her.

"I'm asking you really properly. Just stop. Just think!" the Doctor urges him.

"Use my name," the Master mocks the Doctor.

"Master," the Doctor complies. "I'm sorry…"

"Tough!" the Master snapped back as he starts up the time rotor.

"I can't hold out much longer, Doctor!" Jack shouts at the Doctor, and Katy abandons the Doctor, knowing she couldn't be much help right then and goes to help close the door with Martha and Jack. The Doctor wordlessly activates his sonic screwdriver, fusing the time rotor.

This aggravates the Master.

"Oh, no you don't! End of the universe. Have fun. Bye, bye!" He mocks the four of them as the Tardis dematerialises, leaving the four of them stranded.
