“The final prophecy is in place. The Doctor and his Children of Time all gathered as witnesses. Supreme Dalek, the time has come! Now, detonate the Reality Bomb!”
“Activate planetary alignment field!” the Supreme Dalek announced. “Universal Reality Detonation in two hundred rels.”
Lilith swore in Gallifreyan.
“You can’t, Davros! Just listen to me!” the Doctor begged. “Just stop!”
Davros laughed with insane delight. “Nothing can stop the detonation! Nothing and no one!”
Suddenly, the Vault was filled with a wheezing noise and the Doctor, Lilith, and their companions watched in delighted surprise as the TARDIS materialized. “But that’s…”
“Impossible!” Davros finished.
The doors flew open revealing an incredibly familiar figure surrounded by a bright light. The Tenth Doctor stood in the doorway holding a gun-like device.
Lilith stared at the duplicate of her father. “What the hell?”
“Brilliant!” Jack cheered.
The duplicate Doctor sprinted towards Davros. “Don’t!” the Doctor warned.
Davros zapped the duplicate with a bold of electricity. He fell to the ground, stunned, but not badly hurt. “Activate holding cell.” A holding cell appeared around the duplicate.
Donna ran out of the TARDIS and picked up the weapon. “Doctor! I’ve got it. But I don’t know what to do!” Davros zapped her too. The power sent her flying back towards a control panel.
“Destroy the weapon,” Davros said. The device was exploded by a Dalek’s ray. “I was wrong about your warriors, Doctor. They are pathetic!”
Rose looked from one Doctor to the other, shocked. “How come there’s two of you?”
“Human biological metacrisis,” the Doctor explained. “Never mind that, now we’ve no way of stopping the Reality Bomb!”
The Supreme Dalek started counting down again. “Detonation in twenty rels. Nineteen…”
Davros activated a hologram showing the planets glowing with Z-Neutrino energy. “Stand witness, Time Lords! Stand witness, humans! Your strategies have failed. Your weapons are useless. And, oh, the end of the universe had come.”
“Nine, eight, seven, six, five…”
Lilith noticed something shift out of the corner of her eye. Donna was standing up.
“Four, three, two one…”
The countdown stopped and the hologram disappeared. An alarm sounded as Daleks, humans, and Gallifreyans all looked around in confusion.
Donna grinned confidently. “Oh, closing all Z-Neutrino relay loops using an internalized synchronous back-feed reversal loop?” She flicked a switch on the control panel. “That button there!”
“System in shut down!”
“Explain! Explain! Explain!” demanded the Supreme Dalek.
The Doctor stared at the ginger. “Donna, you can’t even change a plug!”
She smirked. “Wanna bet, Time Boy?”
“You’ll suffer for this!” Davros shouted. He lifted his hand to zap her, but Donna flicked another switch and the electricity turned back onto Davros instead. He yelped in pain.
“Bio-electric dampening field with a retrogressive arc inversion.”
“Exterminate! Exterminate! Exterminate!” the Daleks chorused. The humans looked terrified, but Donna didn’t seem bothered. She worked on a bit of the control panel and looked at the Daleks with a mocking smile. “Weapons non-functional.”
“What? Macrotransmission of a K-filter wavelength blocking Dalek weaponry in a self-replicating energy blindfold matrix.”
The Doctor was stunned. “How did you work that out?”
“Time Lord!” the Metacrisis said. “Part Time Lord!”
“Part human!” Donna declared, delighted. “Oh yes! That was a two-way biological metacrisis. Half Doctor, half Donna!”
“The DoctorDonna!” Lilith realized. “Just like the Ood said, remember? They saw it coming! The Doctor Donna!”
Donna pushed some more controls. “Holding cells deactivated and seal the Vault. Well, don’t just stand there, you skinny boys in suits! You too, Spacegirl! Get to work!” The two Doctors raced to the control panel.
“Stop them! Get them away from the controls!” Davros ordered.
“And spin.” Donna flicked another switch and the Daleks started to spin around, helpless.
“Help me! Help me!”
“And the other way.” The hostile aliens spun in the other direction.
“What did you do?” the Metacrisis marveled.
“Trip-stitch circuit-breaker in the psycho-kinetic threshold manipulator!” Donna beamed.
“But that’s brilliant!”
The Doctor studied the controls. “But why did we never think of that?”
Donna laughed. “Because you two were just Time Lords, you dumbos! Lacking that little bit of human, that gut instinct that comes hand in hand with Planet Earth. I can think of ideas you two wouldn’t dream of in a million years! Ah, the universe has been waiting for me! Now, let’s send that trip-stitch all over the ship! Did I ever tell you?” She held up her hand, wiggling her fingers. “Best temp in Chiswick, one hundred words per minute!”
As Donna worked with the controls, the Daleks that surrounded the Supreme Daleks spun uncontrollably too.
“Motor casing interference!”
“What is happening? Explain!” the Supreme Dalek boomed.
“Come on then, boys, we’ve got twenty seven planets to send home!” Donna declared. “Activate Magnetron!”
“Stop this at once!” Davros advanced menacingly, but Jack appeared in the TARDIS doorway with his gun and the one Rose was carrying earlier. He tossed Rose’s to Mickey. “You will desist!”
Mickey pointed the massive gun at him. “Just stay were you are, mister.”
Lilith shoved a spinning Dalek and it glided away, still helpless. She joined the Doctors and Donna at the controls.
“Off you go, Clom!”
“Back home, Adipose III!
“Adios, Callufrax Minor and Jahoo!”
“Shallacatop, Pyrovillia, and the Lost Moon of Poosh, sorted. Ha!”
Rose stared at the four of them, still confused. “Is anyone going to tell us what’s going on?”
“He,” Donna gestured to the Time Lord, “poured all his regeneration energy into his space hand, I touched the hand, he,” she gestured to the Metacrisis, “grew out of that but fed back into me. But it stayed dormant un my head until the synapses got that little extra spark, kicking them into life. That you, Davros! Part human, part Time Lord. And I got the best bit of the Doctor. I got his mind!”
The corner of Lilith’s mouth quirked up in amusement. “There’s three of him.”
Rose blinked. “Three Doctors?”
Jack laughed. “I can’t tell you what I’m thinking right now.”
“Oh, shut it, Uncle Jack,” Lilith quipped. “Donna is so unique that the timelines were converging on her. A human being with a Time Lord brain.”
“But you promised me, Dalek Caan!” Davros cried. “Why did you now foresee this?”
Dalek Caan giggled.
Lilith raised an eyebrow. “I think he did. Something’s been manipulating time for a while now, making sure Donna Noble was in the right place at the right time.”
“This would always have happened,” Caan said. “I only helped, Collector.”
“You betrayed the Daleks!” Davros accused.
“I saw the Daleks, what we have done throughout time and space. I saw the truth of us, Creator, and I decreed no more!”
The Supreme Dalek appeared in the Vault. Jack cocked his gun. “Heads up!”
“Davros! You have betrayed us!”
“It was Dalek Caan!” Davros protested.
“The Vault will be purged!” the Supreme Dalek bellowed. “You will all be exterminated!” It shot at the control panel.
“Like I was saying. Feel this!” Jack used the huge gun against the Supreme Dalek and blasted it out easily.
The Doctor examined the control panel. “We’ve lost the Magnetron! And there’s only one planet left.”
“Typical,” Lilith snorted.
“We can use the TARDIS.” He dashed inside the ship.
The Metacrisis flicked s few switches on the remains of the control panel. “Holding Earth stability! Maintaining atmospheric shell.”
“The prophecy must complete,” Dalek Caan said. “I have seen the end of everything Dalek, and you must make it happen, Doctor!”
The Metacrisis hesitated for a moment. “He’s right. ‘Cause with or without a Reality Bomb, this Dalek Empire is big enough to slaughter the cosmos. They’ve got to be stopped.”
“Just… just wait for the Doctor!” Donna begged.
“I am the Doctor! Maximizing Dalekanium power feeds! Blasting them back!”
“Dad, wait!” Lilith shouted.
But one by one, Daleks started exploding. The power of it shook the whole Crucible. The Doctor ran out of the TARDIS and stared at the carnage. “What have you done?”
“Fulfilled the prophecy,” the Metacrisis said, firmly.
“Do you know what you’ve done? Now get in the TARDIS! Everyone! All of you, inside! Run! In! In!”
Lilith stood at the doors. “Dad! Rose! Donna! Sarah Jane! Martha! Jackie! Uncle Jack! Micks!” She waved them all in. Only the Doctor was left outside. “Dad, come on!”
Explosions shook the Vault, fire and destruction everywhere. The Doctor extended his hand to Davros. “Davros, come with me! I promise I can save you.”
“Never forget, Doctor. You did this! I name you, forever. You are the Destroyer of Worlds!” Davros screamed as he disappeared behind flames.
“One will leave and one will still die,” Dalek Caan warned the Doctor.
Lilith pulled him into the TARDIS and he ran to the console, pulling a lever. The TARDIS shook violently as they took off, the Crucible exploding behind them. The Doctor contacted Torchwood and Ianto and Gwen opened the Rift Manipulator, sending all the power to the TARDIS. K-9 provided the TARDIS base code.
Everyone stood around the console as the Doctor gave them instructions. “Now then, you lot... Sarah, hold that down. Mickey, you hold that. ‘Cause, you know why this TARDIS always is always rattling about the place? Rose, that, there. It's designed to have six pilots. And I had to do it single-handed. Martha, keep that level. But not any more! Jack, there you go, steady that. Now we can fly this thing... No, Jackie, no, no, not you, don't touch anything, just... stand back…” He gently pushed Jackie away, then returned to his sentence. “Like it’s meant to be flown! We’ve got the Torchwood Rift looped around the TARDIS by Mr. Smith and we’re going to fly Planet Earth back home! Right then! Off we go!”
He pulled a lever and the TARDIS flew off, pulling the Earth along.
Lilith was standing back, watching her friends and her father fly the TARDIS. The Metacrisis joined her. “Not a sight you ever thought you’d see, huh?”
“Oh, I always knew it was coming. In here.” She tapped her temple.
The Metacrisis chuckled, and then sighed. “We both know what he’s going to do.”
“I assume you’re referring to him being a masochistic bastard and leaving Rose in Pete’s World with you?”
He nodded. “Can you really blame him, though? He’s right. I am dangerous.”
“You’re only as dangerous as he is,” Lilith said fiercely, “He destroyed the Daleks too, once. The Daleks and the Time Lords. You did what had to be done. It’s very human of you.”
The Metacrisis flinched, jokingly. “Please don’t say that.” They stood in companionable silence for a few moments. “So, since we’ll likely never see each other again, I don’t suppose you could answer a few overdue questions?”
She looked up at him, curious. “Like what?”
“Well, I’d mostly like to know who your mother is.”
Lilith’s eyes inadvertently drifted to Rose. “She’s someone you love. Does it make a difference whether you know or not?”
The Metacrisis followed her gaze and frowned. “But…how…?”
She shook her head. “How doesn’t matter. You get your forever, Dad. You spend the rest of your life with her. You two are happy. What else matters, really?”
“Nothing, I suppose.” He sighed.
As the Earth arrived back in its correct position, the passengers in the TARDIS laughed, cheered, clapped, and everyone hugged each other. Donna threw herself into Jack’s arms much to most people’s amusement. The TARDIS materialized and Lilith followed the Doctor and Sarah Jane outside.
“You know,” Sarah Jane said, “you act like such a lonely man. But look at you. You’ve got the biggest family on Earth!” She hugged him, and then hugged Lilith.
“This isn’t the last you’ll see of us, Sarah Jane. I promise.” Lilith smiled.
She laughed. “I have to go. He’s only fourteen. It’s a long story. And thank you!”
The Doctor waved to her, smiling. Sarah Jane waved back before turning around and rushing off. Jack and Martha came out of the TARDIS. Lilith hugged both of them.
The Doctor grabbed Jack’s arm and soniced his vortex manipulator. “I told you, no teleport! And Martha, get rid of that Osterhagen thing, hey? Save the world one more time.”
“Consider it done.”
Jack saluted, and so did Martha. Lilith and the Doctor saluted back. The two humans walked away hand in hand. Mickey appeared from the ship.
“Oi, where are you going?” the Doctor asked.
Mickey shrugged. “Well I’m not stupid, I can work out what happens next. And, hey, I had a good time in that parallel world, but my gran passed away. Nice and peaceful. She spent her last years living in a mansion. There’s nothing there for me now, certainly not Rose.”
“What will you do?”
“Anything! Brank new life! Just you watch.” The two men bumped fists.
Lilith hugged him. “See you around, Micks.”
“See you, Lil, Boss.” Mickey ran after Jack and Martha.
The Doctor opened the doors. But instead of going inside, Lilith started to walk away. He followed. “Where do you think you’re going?”
She turned around to face him. “You’re about to make the biggest mistake of your lives. Do you really think I’m going to stick around to watch?”
The Doctor clearly knew what she was talking about. “It’s what’s best for her, Lilith.”
“Is it?” Lilith demanded. “What about what she wants? Did you think to ask her that?”
“I want her to be happy,” the Doctor insisted. “This way, she can have me and grow old with me.”
Lilith sighed. “I know. This is how it turns out, but I just can’t watch you throw your happiness away. That and…” She trailed off.
“I remember you leaving now, don’t I?” he asked quietly. She nodded. “And you’re not coming back this time.”
“You’ll see me two more times,” she told him. “But I won’t be staying.”
The Doctor nodded solemnly. “So this is goodbye, then.”
Lilith’s eyes started watering and she threw her arms around her father, who hugged her back just as tightly. “I love you, Daddy,” she whispered.
“I love you too,” he whispered back. He let go of her and went back into the TARDIS. Lilith watched with tears in her eyes as her home dematerialized.
The universe has to move forward. Pain and loss, they define us as much as happiness or love. Whether it's a world, or a relationship, everything has its time. And everything ends.
