He lands the Tardis in London and exit's it with Donna and Kiam. They stand outside the Tardis and look around at the quiet streets that are normally so busy with people.
"Like a ghost town." Donna says quietly.
"Sarah Jane said they were taking the people. What for? Think, Donna.
When you met Rose in that parallel world, what did she say?" He need more information.
"Just, the darkness is coming." Donna replied.
"Anything else?"
Donna looks over his shoulder "Why don't you ask her yourself?"
His breath leaves his body. Not daring to believe her, he turns around slowly and there she is his beautiful Rose walking down the street towards them. He passes Kiam's hand to Donna and starts walking towards her and then not being to help himself, he starts to run. The world seems to disappear around them and all he can see is her.
The word "Exterminate." Makes him stumble and he feels the Dalek's ray graze his body, knocking him down. He hears a shot and an explosion as the Dalek is taken out. Then she is to next to him. She lifts up his head and holds it gently in his hands. "I've got you. It missed you. Look, it's me, Doctor."
"Rose."
"Hi." She says smiling at him with the smile he missed so much.
"Long time no see." He says.
"Yeah. Been busy, you know." Pain rips through his body as he feels his organs starting to shut down. "Don't die. Oh, my God. Don't die." She says. Jack appears followed by Donna with Kiam in her arms. He didn't want Kiam to see this. He notices Rose's eyes turn towards the little boy with wonder on her face as she tries to figure out if that is the son she had left behind. Jack and Rose help him up and he hears Jack giving the order. "Get him into the Tardis, quick. Move."
They somehow get him into the tardis and lay him on the cold steel as Rose holds his head. "What, what do we do?. There must be some medicine or something." Donna is panicking and Jack takes Kiam from her, stepping away.
"Just step back. Rose, do as I say, and get back." He hears Jack say as the pain grows worse. "He's dying and you know what happens next."
"What do you mean? He can't." Donna says.
"Oh, no. I came all this way." She looks at him sadly.
"What do you mean, what happens next?" He had never explained the process of Regeneration to Donna, but he realizes she is about to find out as he holds up his hand and sees it is starting to glow. "It's starting." He says and watches as Jack grabs Rose and pulls her back to him and Donna.
"Here we go. Good luck, Doctor." Jack says.
"Will someone please tell me what is going on?."
"When he's dying, his er, his body, it repairs itself. It changes. But you can't!" She looks at him so sad and desperate and as he pulls himself up onto his feet. He looks at them one last time and is thankful to see Jack trying to keep Kiam turned away from him. He didn't want his son to see this. "I'm sorry, it's too late. I'm regenerating," As the energy over takes his body and he feels the changes start.
But he isn't ready to go not yet. He forces the Regeneration energy to heal his body and then using all the effort he has left he turns his body and points at the jar with his hand in it, forcing the Energy into his spare hand. The Energy flows into it and he stops glowing.
He turns to his companions. "Now then. Where were we?" He says seeing there stunned looks. He smiles and leans down to the hand and blows the rest of the energy away from it.
"You see? Used the regeneration energy to heal myself, but soon as I was done, I didn't need to change. I didn't want to. Why would I? Look at me. So, to stop the energy going all the way, I siphoned off the rest into a handy bio-matching receptacle, namely my hand. My hand there. My handy spare hand. Remember? Christmas Day, Sycorax. Lost my hand in a sword fight? That's my hand. What do you think?" He rambles on at there stunned faces, until finally Rose steps forward.
"You're still you?" She says.
"I'm still me." He says and gives her a hug. "And there is someone I would like you to meet." He walks over to Jack and takes Kiam from his arms. "Rose I would like to introduce your son, Kiam."
"He's gotten so big." she says in amazement, her eyes filled with tears.
"Well it has been almost two years." He replies.
"I know, I just always.." she cuts off.
"What," he ask.
"I just always pictured him as the tiny baby, I was taken from." As the tears start running down her cheeks. He pulls her to him and holds her tightly. The power flickers and then shuts off. He releases Rose. and hands Kiam back to Donna out of habit. He heads over to the console and looks at the readings.
"They've got us. Power's gone. Some kind of chronon loop." The Tardis jerks and he watches the readings as it starts to move.
"There's a massive Dalek ship at the centre of the planets. They're calling it the Crucible. Guess that's our destination." Jack says.
"Rose, you've been in a parallel world. That world's running ahead of this universe. You've seen the future. What was it?"
"It's the darkness." She replies. "The stars were going out ,One by one. We looked up at the sky and they were just dying. Basically, we've been building this, er, this travel machine, this, this er, dimension cannon, so I could. Well, so I could," She stutters and stops.
"What?" He ask.
"So I could come back. Shut up." She tells him as a giant grin covers his face. "Anyway, suddenly, it started to work and the dimensions started to collapse. Not just in our world, not just in yours, but the whole of reality. Even the Void was dead. Something is destroying everything."
"In that parallel world, you said something about me." Donna says.
"The dimension cannon could measure timelines, and it's, it's weird, Donna, but they all seemed to converge on you."
"But why me? I mean, what have I ever done? I'm a temp from Chiswick." Donna says.
He looks back as his scanner as it begins to beep. "The Dalek Crucible. All aboard."
"Doctor, you will step forth or die." A dalek voice says over the speakers as the Tardis lands.
"We'll have to go out. Because if we don't, they'll get in." He says to the others.
"You told me nothing could get through those doors." Rose says sounding surprised.
"Last time we fought the Daleks, they were scavengers and hybrids, and mad." He takes her gently by the arms, just wanting to feel her and know she is really there. "But this is a fully-fledged Dalek Empire, at the height of its power. Experts at fighting Tardises, they can do anything. Right now, that wooden door is just wood."
"What about your dimension jump?" Jack asks Rose.
"It needs another twenty minutes. And anyway, I'm not leaving." She tells Jack.
"What about your teleport?" The Doctor ask Jack, hoping he could at least take Kiam off the crucible and to some sort of safety.
"Went down with the power loss." Jack tells him crushing his hopes.
"Right then. All of us together. Yeah. Donna?" He turns to look at her and sees the glazed look on her face. He releases Rose and goes over to Donna, gently taking her shoulder. "Donna" he says softly and she turns and looks at him.
"Yeah." She finally answers.
"I'm sorry. There's nothing else we can do." He tells her.
"No, I know."
He tries stalling for time one last time before heading out to face the Daleks. "It's been good, though, hasn't it?" He says. "All of us. All of it. Everything we did." He turns to Donna. "You were brilliant." Then Jack "And you were brilliant." "And you were brilliant. Blimey." He takes a deep breath and opens the doors to the Tardis and steps out with Donna lagging behind, Kiam still in her arms.
The Daleks are celebrating and he realizes that Donna is still on the Tardis. "Donna! You're no safer in there," He calls out to her. The door slams shut trapping her and Kiam inside. "What" he says.
He hears Donna on the other side of the Door. "Doctor? What have you done?"
"It wasn't me. I didn't do anything." He says terrified.
"Oi! Oi, We're not staying behind!" she calls through the door.
He turns towards the Daleks angry. "What did you do?!" He says.
"This is not of Dalek origin." A red Dalek tells him.
"Stop it! She's my friend and that is my son. Now open the door and let them out."
"This is Time Lord treachery." The Dalek responds.
"Me? The door just closed on its own." He yells at them.
"Nevertheless, the Tardis is a weapon and it will be destroyed."
His hearts jump into his throat as a trapdoor opens beneath the Tardis and it falls away.
"What are you doing? Bring it back!" He is panicking. "What have you done? Where's it going?"
"The Crucible has a heart of Z-neutrino energy. The Tardis will be deposited into the core."
"You can't. You've taken the defences down. It'll be torn apart!"
"But Donna and Kiam are still in there!" Rose yells.
"Let them go!" Jack demands.
"The female, the Child and the Tardis will perish together. Observe. The last child of Gallifrey is powerless."
An image of the Tardis bobbing in the molten core appears. He starts to plead with them "Please. I'm begging you. I'll do anything! Put me in their place." They ignore him and he raises his voice. "You can do anything to me, I don't care, just get them out of there!"
"Total Tardis destruction in ten rels." They count down to one while he uses those ten seconds to come up with anything to get them out. He feels a piece of him die as he watches the Tardis vanish.
"The Tardis has been destroyed. Now tell me, Doctor. What do you feel? Anger? Sorrow? Despair?"
Numb, "Yeah." He answers. Donna was gone. He couldn't think of Kiam being in there too, if he did he didn't think he could save anyone else. He looked down not wanting to look at Rose knowing he had failed her. He had kept their son alive for almost two years and right as she was reunited with them he had failed. Tears streamed silently down his cheeks.
"Then if emotions are so important, surely we have enhanced you?" The Dalek Taunted him.
"Yeah? Feel this!" He hears Jack say followed by the sound of a gun shot.
"Exterminate!" He hears the Dalek's ray guns and then Rose screaming. "Jack. Oh, my God."
"Rose, come here. Leave him." He says finally lifting up his head and heading over to her.
"They killed him." She was crying too.
"I know. I'm sorry." he says, realizing she doesn't know about Jack.
"Escort them to the Vault. They are the playthings of Davros now."
He goes with the Daleks barely trusting his legs to keep going. "Kiam is dead." just kept repeating over and over in his head. "Oh god let this be a dream." He pinches his arm and feels the pain. He looks over at Jack and sees Jack blink. He catches Jack's eyes and then turns away.
They are lead down to the vaults and separated from each other. "Activate the holding cells." He hears one of them say and a beam comes down and surrounds them.
"Excellent. Even when powerless, a Time Lord is best contained." Davros taunts him.
"Still scared of me, then?" He says barely trusting his own voice.
"It is time we talked, Doctor. After so very long."
"No. We're not doing the nostalgia tour." He was angry. He let the anger flow through him and over take the pain he was feeling. "I want to know what's happening right here, right now, because the Supreme Dalek said Vault, yeah? As in dungeon, cellar, prison." It dawned on him and he could have smiled. "You're not in charge of the Daleks, are you? They've got you locked away down here in the basement like, what, a servant? Slave?"
"We have an arrangement." Davros says.
"No, I've got the word. You're the Dalek's pet!"
"So very full of fire, is he not." Davros heads over to Rose. "And to think you crossed entire universes, striding parallel to parallel to find him again."
"Leave her alone." He screams at Davros.
"She is mine to do as I please."
"Then why am I still alive?" She ask and the pain flows over him all over again as he hears how broken she sounds. He dares a look at her and sees his once strong Rose Tyler about to fall apart.
"You must be here. It was foretold. Even the Supreme Dalek would not dare to contradict the prophecies of Dalek Caan."
"So cold and dark. Fire is coming. The endless flames." Caan Laughed.
"What is that thing?" She asked.
"You've met before. The last of the Cult of Skaro." That horrible day, he adds silently to himself. "But it flew into the Time War, unprotected."
"Caan did more than that. He saw time. Its infinite complexity and majesty, raging through his mind. And he saw you. Both of you."
"This I have foreseen, in the wild and the wind. The Doctor will be here as witness, at the end of everything. The Doctor and his precious Children of Time. And one of them will die." Caan laughs again.
"Was it you, Caan? Did you kill Donna and Kiam?" His voice catches as he says the name, but he continues. "Why did the Tardis door close? Tell me!" The anger is back.
"Oh, that's it. The anger, the fire, the rage of a Time Lord who butchered millions. There he is. Why so shy? Show your companion. Show her your true self. Dalek Caan has promised me that too."
"I have seen. At the time of ending, the Doctor's soul will be revealed."
"What does that mean?"
"We will discover it together. Our final journey. Because the ending approaches. The testing begins." Davros tells him.
"Testing of what?"
"The Reality bomb." Davros turns towards a screen and he looks at it. He sees a group of people standing there. Now knowing what the twenty seven planets were taken for he pleads with Davros.
"No, Davros. Davros, you can't! You can't! No!" But he watches feeling helpless as the prisoners are disintegrated.
"Doctor what happened." Rose asks but he can't answer her. After a pause he hears Davros explain that the reality bomb can dissolve everything in the universe, changing everything in its path to smaller and smaller particles until they are nothing.
"This is my ultimate victory, Doctor! The destruction of reality itself!" Davros says to him.
"This message is for the Dalek Crucible. Repeat. Can you hear me?" He hears Martha say.
"Put me through." He says, his voice barely above a whisper.
"It begins As Dalek Caan foretold." Davros gloats.
"Put me through!" He says again his voice a little stronger this time.
Martha appears on the screen. "Doctor! I'm sorry, I had to."
"Oh, but the Doctor is powerless. My prisoner. State your intent." Davros says.
"I've got the Osterhagen Key. Leave this planet and its people alone or I'll use it."
"Osterhagen what?" he had never heard of it. "What's an Osterhagen Key?"
"There's a chain of twenty five nuclear warheads placed in strategic points beneath the Earth's crust. If I use the key, they detonate and the Earth gets ripped apart." Martha says.
"What? Who invented that?" Feeling slightly dumb at his statement. "Well, someone called Osterhagen, I suppose." He couldn't believe she would even suggest such a thing. "Martha, are you insane?"
"The Osterhagen Key is to be used if the suffering of the human race is so great, so without hope, that this becomes the final option." She explains.
"That's never an option." He says coldly.
"Don't argue with me, Doctor, because it's more than that. Now, I reckon the Daleks need these twenty seven planets for something. But what if it becomes twenty six? What happens then? Daleks? Would you risk it?"
"She's good." Rose says.
"Who's that?" Martha asks.
"My name's Rose. Rose Tyler." She tells Martha.
"Oh, my God. He found you." Martha says.
A second image appears on the screen. "Captain Jack Harkness, calling all Dalek boys and girls. Are you receiving me? Don't send in your goons, or I'll set this thing off." He sees two people standing with Jack.
"He's still alive." Rose says and then noticing the people with Jack. "Oh, my god. That, that's my mum." She says.
"And Mickey. Captain, what are you doing?" He says.
"I've got a Warp Star wired into the mainframe. I break this shell, the entire Crucible goes up."
"You can't! Where did you get a Warp Star?" He couldn't believe what he was hearing. First that bloody key, now this."
"From me." Sarah Jane appears on the screen with Jack. "We had no choice. We saw what happened to the prisoners."
"Impossible. That face. After all these years." Davros says.
"Davros. It's been quite a while. Sarah Jane Smith. Remember?"
"Oh, this is meant to be. The circle of Time is closing. You were there on Skaro at the very beginning of my creation."
"And I've learnt how to fight since then. You let the Doctor go, or this Warp Star gets opened."
"I'll do it. Don't imagine I wouldn't." Jack says.
"Now that's what I call a ransom." Rose sounds happy. "Doctor?" she says but he can't answer. After Kiam and Donna died his hearts had been broken and he didn't think they could hurt anymore until this. He felt as though they had been ripped from his chest and were being stomped on. He couldn't even begin to express his disappointment and the scene unfolding in front of him. All these people he called friends. They had all been so kind in the beginning and he had turned them all into killers.
"And the prophecy unfolds." Davros begins as though he could read his mind he continued. "The man who abhors violence, never carrying a gun. But this is the truth, Doctor. You take ordinary people and you fashion them into weapons. Behold your Children of Time transformed into murderers. I made the Daleks, Doctor. You made this."
"They're trying to help." He says finally finding his voice again.
"Already I have seen them sacrifice today, for their beloved Doctor. The Earth woman who fell opening the Subwave Network."
"Who was that?" He ask.
"Harriet Jones. She gave her life to get you here."
"How many more? Just think. How many have died in your name? The Doctor. The man who keeps running, never looking back because he dare not, out of shame. This is my final victory, Doctor. I have shown you yourself."
There is a flash of light and all of his companions on the screen are standing in the vault with him. Jack starts to head towards him.
"Don't move, all of you. Stay still." he says.
"Guard them! On your knees, all of you. Surrender!" Davrose demands.
Not wanting to see anymore deaths he tells them to listen to Davros and watches them get on their knees, hands in the air.
"The final prophecy is in place. The Doctor and his children, all gathered as witnesses. Supreme Dalek, the time has come. Now, detonate the Reality bomb!"
"You can't, Davros! Just listen to me! Just stop!"
"Ah, ha, ha, ha! Nothing can stop the detonation. Nothing and no one!"
