I do not own Doctor Who. All I own is this story and my OC.

Please review and no flaming will be tolerated. Thank you :)

PARTING IS SUCH SWEET SORROW

"And I think you're so mean; I think we should try.
I think I could need this in my life, and
I think I'm scared; I think too much.
I know it's wrong, it's a problem I'm dealing'" – Matchbox Twenty: 'If You're Gone' (Mad Season [2000]).

Battersea Power Station

So far so good, as far as Pete, Katy, and Rose's infiltration into the Power Station was concerned. They were still alive and whole. But the overhead announcements were making it extremely difficult to maintain blank, emotionless expressions on their faces, when all they could think of were the hundreds of innocent Londoners walking silently towards their deaths, and re-emerging as Cybermen.

"Units upgraded now six thousand five hundred. Repeat. Six thousand five hundred and rising." A Cyberman stops the procession at Rose. Both Pete and Katy are standing right behind her.

"You will wait," the Cyberman tells Rose, as it moves away.

"You girls, okay?" Pete asks quietly.

"No," Rose responds shakily.

"I've been better," Katy answered, also just as shaky as her sister was.

"Chamber six now open for human upgrading. All reject stock will be incinerated." Katy's eyes widened slightly. There were people who were actually being rejected for upgrading, and being killed anyway?

'This is sick…' Katy whimpered mentally. A woman ahead of them walks into a chamber. Overhead, multiple blades whir into action, then a Cyber head is lowered. Seconds later, a complete Cyberman walks out of the chamber, and it clomps away. Pete's eyes dart about the area, obviously desperately looking for a hint or a whisper of his wife.

"Any sign of Jackie?" He mutters. But before either sister could respond to his question, a Cyberman breaks ranks and clomps up to them. Pete has to stop himself rearing back from it instinctively.

"You are Peter Tyler," It states robotically. "Confirm you are Peter Tyler!" It orders. Pete swallows before responding to the command.

"Confirmed."

"I recognise you," It stated, earning confused expressions from all three Tylers. "I went first. My name was Jacqueline Tyler."

"What!?" both Pete and Katy exclaimed.

"NO!" Rose shouted in anguish. The Cyberman immediately reacts.

"They are unprogrammed. Restrain." Three Cybermen approach and apprehend Pete, Katy, and Rose. Pete looked tearful and hysterical.

"You're lying!" He denied. "You're not her. You're not my Jackie!" He thrashed about trying to break free from the iron grip the Cyberman restraining him had on his arms.

"No," the Cyberman formerly known as Jackie Tyler, responded. "I am Cyber-form. Once I was Jacqueline Tyler."

"But you can't be. Not her!" Rose protested.

"Her brain is inside this body," the Cyberman insisted. Pete tried freeing himself fruitlessly, as he attempted to get through to the brain of his wife that had been welded into this body of steel.

"Jacs, I came to save you!" He insisted, in vain. The Cyberman ignored him, before turning to its peer beside it.

"This man worked with Cybus Industries to create our species," It stated. "He will be rewarded by force. Take them to Cyber Control." Pete, Katy, and Rose are escorted away. Katy was stunned but had to remind herself that that Cyberman was NOT her real mother; and that Jackie was safely back at home in the real reality, probably on the phone gossiping with her friends while drinking endless cups of tea. Completely, and blissfully unaware that her counterpart had been killed, and that both her daughters, the Doctor and Mickey were all in deep peril.

"They killed her," Rose muttered. "They just took her and killed her."

"Maybe there's a chance, I don't know." Pete reasoned. "Maybe we can reverse it."

"There's nothing we can do," Katy piped up, grimly.

"But if, if she remembers…" Pete trailed off before looking back the way they came from and started scanning the crowd of Cybermen. "Where is she? Which one was it? Which one was her?"

"They all look the same," Rose said, sadly.

Lumic's Zeppelin

The unconscious body of a guard is dumped unceremoniously onto the ground with both Mickey and Jake standing over him, triumphantly. Jake offered Mickey a half-smile, impressed.

"Nice one," he complements him, before glancing around the room for any other signs of life. "Nobody's home," He realises before glancing back over at Mickey again, this time all business. "Find the transmitter controls."

"What do they look like?" Mickey asks, heading over to some nearby buttons and knobs.

"Well, I don't know," Jake retorted. "They might have 'transmitter controls' written in big red letters." He added, sarcastically. This earned him an irritated glare from Mickey for the tone. "Just look!" The Zeppelin has a nice big ship's wheel for steering. However, when Mickey pulls open a nearby door, he jumps back in fright and immediately prepares to defend himself, drawing Jake's attention. "Cyberman!" Jake goes over to it with a large pistol, ready to discharge it at the Cyberman. He turns on the alcove light and pauses.

"It's dead," Mickey confirms. "I don't think it was ever alive," He wraps his knuckles three times on the metal head. "It's empty. No brain. It's just a robot suit. It's for display."

"Okay. Transmitter," Jake states, and Mickey does what he's told and goes off to locate the transmitter.

Corridor

The Doctor and Missus Moore continue on their way down the corridor when they both unexpectedly come across a lone Cyberman.

It confronts them.

"You are not upgraded," It states. Missus Moore glares at it, while digging around in her bag.

"Yeah? Well, upgrade this," She tosses a small rod with copper wire wrapped around it at the Cyberman. It sticks to its metal body, causing the Cyberman to jerk, before it sparks and collapses to the floor. The Doctor is impressed.

"What the hell was that thing?" He asks.

"Electromagnetic bomb," Missus Moore replied. "Takes out computers, I figured it might stop the cybersuit," She shrugged.

"You figured right," The Doctor squats beside the deactivated cyberman, pulling his sonic screwdriver from his pocket. "Now, let's have a look." He examines the cyberman's logo on the centre of its chest and attempts to open it by using the old 'righty-tighty, lefty-loosey' technique. It doesn't budge, but the Doctor is by no means stalled in his examination. "Know your enemy," He uses his sonic around the edges of the logo. "A logo on the front. Lumic's turned them into a brand. Heart of steel," He manages to get it open. "Heart of steel," He looks inside and raises an eyebrow at what he sees. "But look!" Inside the cyberman's chest were electronics, and something white that looked like tripe.

Missus Moore frowned.

"Is that flesh?" She pondered. The Doctor reaches in and pulls some of the white stuff aside with his fingers, running his thumb over it curiously.

"Hmmm. Central nervous system," He reveals. "Artificially grown then threaded throughout the suit so it responds like a living thing." Then he amends what he just said. "Well, it is a living thing," then he spots something interesting hidden among the artificial flesh. "Oh but look. Emotional inhibitor. Stops them from feeling anything."

"But why?" Missus Moore asks.

"It's still got a human brain," the Doctor states. "Imagine its reaction if it could see itself, realise itself inside this thing. They'd go insane."

"So, they cut out the one thing that makes them human?"

"Because they have to," the Doctor confirmed.

"Why am I cold?" The Cyberman suddenly asks, startling the both of them. Missus Moore's eyes widen in shock.

"Oh, my God. It's alive. It can feel," she said, horrified.

"We broke the inhibitor," the Doctor realises, before grimacing remorsefully at the cyberman. "I'm sorry. I'm so sorry." He apologises.

"Why so cold?" The cyberman repeats its question.

"Can you remember your name?" the Doctor gently asks, changing the subject.

"Sally. Sally Phelan." The Cyberman replied.

"You're a woman," Missus Moore stated.

"Where's Gareth?" The cyberman asks.

"Who's Gareth?" Missus Moore answered.

"He can't see me," The cyberman stated, and both the Doctor and Missus Moore froze in horror and sympathy. "It's unlucky the night before."

"You're getting married." Missus Moore's eyes welled up with tears. This was probably the saddest situation they had ever been put into. She looked up and saw the Doctor wearing a grim expression on his face.

"I'm cold. I'm so cold," The cyberman stated. The Doctor pulls out his screwdriver again.

"It's all right," He soothed the cyberman. "You sleep now, Sally. Just go to sleep." He puts the sonic screwdriver inside the chest cavity and switches her off. "Sally Phelan didn't die for nothing, because that's the key." He revealed. "The emotional inhibitor. If we could find the code behind it, the cancellation code, then feed it throughout the system into every Cyberman's head, they'd realise what they are."

"And then what happens?" Missus Moore asked.

"I think it would kill them," The Doctor realised, and looked regretful. "Could we do that?"

"We've got to. Before they kill everyone else," Missus Moore stated, sounding determined despite the horrible conversation they had just had with a cyberman who a young bride-to-be had previously been. "There's no choice, Doctor. It's got to be done." She stands up … then immediately gets electrocuted with another Cyberman suddenly grabs her shoulder without warning. The Doctor protests loudly as her body tumbles to the ground.

"No! No, you didn't have to kill her!"

"Sensors detect a binary vascular system," The second Cyberman reports. "You are an unknown upgrade. You will be taken for analysis." The Doctor is forcibly taken away, as he turns and looks down at Missus Moore's lifeless body with regret and sorrow.

Lumic's Zeppelin

The boys were still searching for the transmitter controls to cancel out the signal forcing everyone to walk blindly into the Battersea Power Station to become emotionless, walking metal men, when Mickey suddenly hits the jackpot, finding what they were searching for in a something that resembled a power grid.

"The transmitter controls are sealed behind here," Mickey revealed struggling to remove it. "We need like an oxyacetylene or something."

"Oh, and I forgot to bring it with me," Jake retorts sarcastically. Mickey scowls and rounds on him, getting annoyed with the other boy's sarcasm.

"Well then, what do we do?" He challenged.

"We'll crash the Zeppelin," Jake shrugged, like it should've been obvious. Mickey just looks at him exasperated.

"With us inside it?"

"We could set it to automatic and then just leg it," Jake suggested. "Let's have a look." They go back over to the steering controls keyboard. But they have no luck getting into it. "It's locked. There's got to be an override."

"Let me have a go," Mickey said, getting past Jake to gain access to the computer. "I'm good with computers. Trust me." As Mickey works, a red light on the back of the keyboard blinks, causing the Cyberman in the alcove to turn towards them.

Control room

Rose and Katy sit quietly together on some nearby chairs, with Pete hovering nearby looking grief-stricken, while a couple of Cybermen stand guard to ensure that they don't make a run for it. The Doctor is led inside. But he scowls in annoyance when he spots the three of them sitting there, obviously having been caught and brought in like him.

"I've been captured, but don't worry, Rose, Katy, and Pete are still out there. They can rescue me," the Doctor quipped sarcastically before sighing in defeat. "Oh well, never mind." Then he takes a real look at the shell-shocked, tear streaked and grief-stricken expressions on their faces and mellows. "You girls, okay?"

"Yeah," Katy responds quietly.

"But they got Jackie," Rose adds, which starts Pete up and he looked angry and tearful.

"We were too late," Pete declared. "Lumic killed her." The Doctor turns about the room, raising his voice to be heard by whoever happened to be nearby.

"Then where is he, the famous Mister Lumic?" He inquired. "Don't we get the chance to meet our Lord and Master?" His voice dripped with mocking, and one of the Cybermen steps forward.

"He has been upgraded."

"I'm shocked," Katy drawled angrily, wiping the tears still falling down her face with her hand.

"So, he's just like you?" The Doctor questioned the Cyberman.

"He is superior," the Cyberman corrected him. "The Lumic Unit has been designated Cyber Controller." A nearby door opens and a Cyberman is wheeled out in an upgraded wheelchair … very obviously Lumic. The four of them eye him in a mingled combination of shock, horror, and disgust.

"This is the Age of Steel, and I am its Creator." Lumic declares triumphantly.

Lumic's Zeppelin

Mickey's fingers were flying over the keyboard, with a mildly impressed Jake hovering over his shoulder looking at his work. Neither of them had noticed the Cyberman gradually waking up behind them.

"Almost there," Mickey confirms.

"Not bad work," Jake complimented him. The Cyberman's hand flexes, grabbing both boy's attention and Jake jumps back out of self-preservation. "It's moving!" He glares accusingly at Mickey who is equally as surprised that the Cyberman was in fact mobile. "You said it was dead!"

"Yeah," Mickey responded sheepishly. "But a robot's still a big robot." Then he glances over at a nearby panel, immediately getting an idea. "Wait a minute," He looks over at the Cyberman and calls out to it. "Hey, Cyberman, over here. Come on, you brainless lump of metal. Come and have a go!" He taunts the metal humanoid who ambles towards the boys.

Mickey deliberately stands in front of the panel, labelled 'transmitter controls' and beckons towards it. He ducked as the cyberman smashes its fist into the panel and electrocutes itself.

"The transmitter's down!" Mickey shouts triumphantly.

Battersea Power Station

All of the ear pods immediately stop flashing, and the unconverted people lining up to be 'upgraded' wake up from their motionless trances. They look about in bewilderment, until they finally register exactly where they were.

"Oh no!" A woman exclaimed, before everyone suddenly starts screaming and panicking and pushing their way past the cybermen to get outside.

Control room

The shouting and screaming can be heard from the control room, making the Doctor grin from ear to ear in triumph.

"That's my friends at work," he tells Lumic. "Good boys! Mister Lumic, I think that's a vote for free will." However, Lumic doesn't sound exactly fazed that his plan to convert London into an army of Cybermen had failed.

"I have factories waiting on seven continents. If the ear pods have failed, then the Cybermen will take humanity by force." He vowed, and the grin falls abruptly from the Doctor's face, replaced with horror, anger and disgust.

Lumic's Zeppelin

Their current threat out of commission and having helped him and Jake disconnect the Londoners from their grisly fates, Mickey commandeers the panel again and resumes typing away at the keyboard.

He makes a sound of triumph.

"Hold on, I've logged on to Cyber Control," he tells Jake, who immediately comes over to see for himself. Sure enough, both boys have got a bird's eye view of the control room where the Doctor, Katy, Rose, and Pete were being held hostage by an upgraded Lumic. Mickey sags in relief. "They're alive! The Doctor, Katy, and Rose, there they are!"

"Never mind them," Jake points towards Lumic on the monitor. "What the hell is that thing?"

"Shush. Has this thing got sound?" Mickey quickly looks around for the volume. Suddenly, Lumic's robotic Cyberman voice floods the room, making it easier for Mickey and Jake to eavesdrop on the entire conversation.

"I will bring peace to the world. Everlasting peace..." Jake and Mickey exchange dubious looks with each other before focusing back on the scene in front of them.

Control room

"…And unity and uniformity," Lumic promised, earning a scoff from the Doctor who was still eyeing him like he was something particularly disgusting he had found stuck to the bottom of his converse.

"And imagination?" He challenged. "What about that? The one thing that lead you here, imagination, you're killing it dead!" He pointed out.

"What is your name?" Lumic questioned.

"I'm the Doctor."

"A redundant title," Lumic sneered. "Doctors need not exist. Cybermen never sicken."

"Yeah, but that's it. That's exactly the point!" The Doctor suddenly looked positively triumphant and gleeful, much to the confusion of everyone in the room. However, both Katy and Rose got over their confusion fairly quickly, as they were used to the Doctor's bipolar changes in mood. After a while, it sometimes became a little exhausting. "Oh, Lumic, you're a clever man," the Doctor complimented the wheelchair bound Cyberman in front of him. "I'd call you a genius, except I'm in the room."

This earned an amused snort and roll of the eyes from Katy whom the Doctor aimed a grin and wink at before continuing on with his tirade, while Rose just continued looking a little lost, and Pete frowned at Katy looking mystified.

"But everything you've invented; you did to fight your sickness. And that's brilliant. That's so human. But once you get rid of sickness and mortality, then what's there to strive for, eh?" The Doctor asked rhetorically. "The Cybermen won't advance. You'll just stop. You'll stay like this forever. A metal Earth with metal men and metal thoughts, lacking the one thing that makes this planet so alive: People. Ordinary, stupid, brilliant people."

"You are proud of your emotions," Lumic stated.

"Oh, yes!" The Doctor confirmed.

"Then tell me, Doctor," Lumic rolled forward a little. "Have you known grief, and rage, and pain?" The Doctor glanced at both his companions out the corner of his eye and nodded, a shadow passing over his face.

"Yes," He responded. "Yes, I have."

"And they hurt?"

"Oh, yes."

"I could set you free," Lumic offered, earning a blank look from the Doctor. "Would you not want that? A life without pain?"

"You might as well kill me," the Doctor retorted automatically, shoving his hands into his pants pockets, and shifting his weight casually onto one of his legs.

"Then I take that option," Lumic decided. The Doctor shook his head, knowing a lost cause when he saw it, before letting out a humourless laugh.

"It's not yours to take," He countered. "You're a Cyber Controller. You don't control me or anything with blood in its heart," He gestures towards the three other people in the room: Katy, Rose, and Pete.

"You have no means of stopping me," Lumic insisted. "I have an army. A species of my own."

"You don't get it, do you? An army's nothing," the Doctor insisted. "Because those ordinary people, they're the key. The most ordinary person could change the world." The Doctor suddenly angles himself towards a nearby security camera he had spotted during his lecture.

Lumic's Zeppelin

Mickey and Jake are still watching the scene from the Zeppelin, although both of them are wondering where the Doctor was heading with this speech about ordinary people. They both react in surprise when the Doctor looks directly at them.

"… Some ordinary man or woman, some idiot…" The Doctor babbled on, and Mickey's eyes widen in realisation when he realises that the Doctor was subtly giving him a signal. "All it takes is for him to find, say… the right numbers? Say... the right codes?" Mickey immediately launches himself towards the computer monitor and starts typing away at it, with Jake observing this with a confused look on his face. "Say, for example, the code behind the emotional inhibitor. The code right in front of him." Mickey's fingers fly over the keyboard. "Because even an idiot knows how to use computers these days. Knows how to get past firewalls and passwords. Knows how to find something encrypted in the Lumic Family Database, under, er, what was it, Pete? Binary what?" The Doctor looks casually at Pete, who by now has realised what the Doctor was up to, as did Katy and Rose, and he chimed in helpfully.

"Binary nine," Pete answered quickly.

"Binary nine," Mickey muttered and quickly adds it to the algorithm he was typing into the system, as Jake smirks, realising what was going on and chuckles triumphantly. The Doctor continues talking over the monitor.

"An idiot could find that code. Cancellation code. And he'd keep on typing. Keep on fighting. Anything to save his friends."

Control room

Lumic remained oblivious to the plan currently underway right underneath his 'nose' and scoffs acerbically.

"Your words are irrelevant," he stated. The Doctor shrugged, agreeing with him as he continued pacing about the room.

"Yeah, talk too much, that's my problem," He turned towards Rose, who blinks at him in surprise. "Lucky, I got you that cheap tariff, Rose, for all our long chats. On your phone," He makes the phone gesture with his thumb and forefinger towards the camera, just as Mickey finally gets the code: 6879760 up on the monitor. He immediately snatches his phone from his pocket and types in the code via a text message.

"You will be deleted!" Lumic warns the Doctor.

"Yes. Delete, control, hash. All those lovely buttons. Then, of course, my particular favourite, send," He points at the security camera. "And let's not forget how you seduced all those ordinary people in the first place—" Rose's phone beeps in her pocket, and she pulls it out and accesses the text message from Mickey. "By making every bit of technology compatible with everything else."

"It's for you," Rose quickly tosses her phone to the Doctor who catches it without looking at her.

"Like this," the Doctor puts Rose's phone into a docking station which conveniently fits the shape of the phone. The code is transmitted and every Cyberman start crying out in pain.

"YES!" Mickey and Jake shout triumphantly back in the Zeppelin. Cybermen everywhere clutch at their heads in pain, much to the horror and remorse of the Doctor, who witnesses a nearby Cyberman catching its reflection in a shiny piece of metal and touching it in horror.

"I'm sorry," the Doctor mutters with regret. Lumic looks about in horror, as his life's work is being destroyed all around him.

"What have you done!?" He roars. The Doctor looks at him with a very dark look on his face.

"I gave them back their souls," He explains. "They can see what you've done, Lumic, and it's killing them!" He grabs Katy's hand and legs it out a nearby door with Rose and Pete following them.

"Delete! Delete! Delete!" Lumic mechanically chanted in his anger.

Battersea Power Station

The entire power station is exploding all around them as the Doctor, Katy, Rose, and Pete run for safety. They run for the nearest emergency exit and wrench open the door, only to come across some Cybermen writhing in agony. The Doctor slams the door shut and looks frantically around for another alternative route out.

But there are none to be seen.

"There's no way out!"

Lumic's Zeppelin

Jake is at the steering wheel of the Zeppelin and immediately spins it, which steers the aircraft away from the power station. Mickey immediately objects.

"What're you doing?"

"We've got to get away," Jake states like it should've been obvious what he was attempting to do. "If that factory blows up, this balloon's going to ignite."

"Take it back!" Mickey exclaimed. Jake looks at him with both irritation and pity.

"Mickey, they've had it!"

"I said, take it back!" Mickey was forceful and stubborn. "We're not leaving them behind. There's no way we're leaving them behind!" He grabs onto the wheel, attempting to hip-check Jake out of the way. But Jake fights back. In the end, Mickey wins the brief battle and spins the wheel back to steer the Zeppelin back to the power station roof. "Hold it!" He passes his phone to a sulking Jake after dialing and indicates for him to hold it to his ear. "Katy? Katy, can you hear me? Head for the roof!"

Battersea Power Station

Katy pulls her phone away from her ear and looks at it in astonishment, before looking up at the Doctor, Rose, and Pete.

"That's Mickey. He says head for the roof," She instructs, and without another word, the Doctor (who once again grabs Katy's hand and leads the way), Rose, and Pete run up a nearby metal staircase as fires start breaking out behind them. Meanwhile, back in the control room, Lumic, in his rage, disconnects himself from the wheelchair and stands up for the first time in years.

"NO!" he roars.

He stomps his way out to follow his saboteurs. The four in question make it to the roof via the metal ladder and immediately spot the Zeppelin with Mickey and Jake standing at the bridge window and Mickey at the wheel. Rose rushes over to Katy's side and shouts down her sister's phone to her ex.

"Mickey, where'd you learn to fly that thing?" She demanded.

Lumic's Zeppelin

Mickey, who was struggling a little underneath the weight of the aircraft he was attempting to steer, responds distractedly to Rose's question.

"PlayStation," On the roof, both sisters grin in remembrance of Mickey's love of video games. "Just hold on, guys. I'm coming to get you," Mickey promises them.

"You can't go any lower," Jake points out.

"I've got to," Mickey insisted, stubbornly.

"You're going to crush them," Jake states, causing Mickey to pause and look around in frustration.

"There's got to be something, there's got to be," Then he spots the in case of emergency lever, and grins. "Oh, yes!" He pulls it down, releasing a trapdoor that opens up and a rope ladder falls free above the four trapped on the roof.

Power Station roof

Pete eyes the rope ladder flapping in the breeze the Zeppelin was giving off as it hovers above them all, and scoffs incredulously.

"You've got to be kidding."

"Obviously he's not. C'mon, we gotta go!" Katy stated, and the Doctor pushes Rose towards the ladder.

"Rose, you first. Get up!" The Doctor instructs, and Rose steps on the first rung and heaves herself up, followed by Katy, then the Doctor and Pete last. All four of them strain uncomfortably as they climb up. It is not exactly the easiest obstacle to accomplish when the rope ladder was flapping about dangerously, with all of them attached to it at the same time.

"Hold on tight, we're going up!" Mickey's voice sounds over a loudspeaker. "Welcome to Mickey Smith's Airline. Please enjoy your flight. WOO!" He cheers, earning a fond chuckle from both Katy and Rose as the Zeppelin rises into the air.

"We did it! We did it!" Rose cheers triumphantly. Then something heavy pulls at the ladder, nearly dislodging them from the ladder, and they all look down to see what the disruption was.

"Oh, what the hell!?" Katy growls exasperatedly. The disruption turned out to be Lumic who had managed to catch up with them and was in the process of climbing up the ladder with them. The Doctor rummages around in his pocket and pulls out the sonic screwdriver.

"Pete!" He looks up at the Doctor. "Take this!" The Doctor drops the screwdriver and Pete catches it, looking at it with confusion. "Use it! Hold the button down! Press it against the rope!" The Doctor instructs, then groans impatiently when Pete hesitates. "Just do it!"

Pete with a look of raw determination on his face, reaches down to the bottom rung of the ladder and aims the blue tip of the screwdriver to the side of the rope. Lumic pauses mid-climb watching him.

"Jackie Tyler. This is for her!" Pete passionately declares as he presses firmly down on the button on the side of the screwdriver. The rope snaps and gives way, causing Lumic to plummet off his own Zeppelin.

"ARGH!" He screams as he is engulfed in the flames of the exploding Power Station.

Lambeth Pier

The group abandon Lumic's Zeppelin after Mickey parks it somewhere off the beaten track nearby Lambeth Pier where the TARDIS was still waiting for the Doctor, Katy, Rose, and Mickey, and the recharging power cell the Doctor still had on his person.

The Doctor immediately makes a beeline inside the TARDIS and immediately puts the power cell back into the console, which causes the TARDIS to light up. He grins with relief and excitement. Outside, Pete eyes the blue box shrewdly from where he was standing with Katy and Rose nearby the same bus shelter his advertisement was attached to.

"So, what happens inside that thing, then?" He questioned the girls, curiously.

"Do you want to see?" Katy responded, hooking her thumb in the direction of the TARDIS, but Pete instantly shakes his head.

"No, I don't think so," He declines politely. "But you two," Pete indicates towards the TARDIS where the Doctor was still getting the TARDIS to start up to normal capacity, and back at Rose. "You know, all that stuff you said about different worlds. Who are you?" He asked, frowning a little.

"It's like you say," Rose replied shrugging a little. "Imagine there are different worlds, parallel worlds. Worlds with another Pete Tyler and Jackie Tyler's still alive … and their daughter." Rose hints, earning a scowl from Katy for being forgotten once again.

"Daughters," Katy corrects, looking shyly at Pete who swallows hard, looking overwhelmed by the information he was receiving from this strange blonde girl, and his niece who apparently wasn't really his niece at all, but another 'daughter'.

"I got to go," Pete decides and goes to leave, but Rose stops him.

"But if you just look inside—" Rose insisted.

"No, I can't," Pete interrupts. "There's all those Lumic factories out there. All those Cybermen still in storage. Someone's got to tell the authorities what happened, carry on the fight…"

The Doctor steps from the TARDIS, looking about for Katy, Rose, and Mickey, before spotting the sisters and shouting out at them to grab their attention.

"Katy? Rose? I've only got five minutes of power. We've got to go!" He reports and both Katy and Rose look apologetically at Pete, who continues to look awkwardly at them. Rose attempts to persuade Pete again.

"The Doctor could show you," She offers.

"Thank you. For everything," Pete ignores the invitation, choosing to just let them leave. But he pauses and looks at Katy. "You're not really my niece, are you?" Katy shakes her head, smiling both sadly and apologetically at him.

"No. I'm sorry," Katy tells him and Pete's face falls before he nods and turns to walk away, but Rose once again stops him.

"Dad…" She says, and Pete flinches and backs off quickly.

"Don't. Just, just don't." He mumbles and walks briskly down the street away from them and out of sight. Rose looks anguished, while Katy eyes her sister for a moment longer, before she chooses to walk off herself, going towards Mickey who comes over carrying the Doctor's brown pinstripe suit in his hands.

"Here it is," He tells the Doctor who grins in relief as he hands it to him. "I found it. Not a crease."

"My suit!" The Doctor exclaimed. "Good man!" He claps a hand on Mickey's shoulder before turning and looking solemnly at Jake. "Now then, Jake, we've got to run. But one more thing. Missus Moore. Her real name was Angela Price. She's got a husband out there, and children. Find them. Tell them how she died saving the world," He instructs, and Jake smiles and nodded.

"Yeah, course I will."

"Off we go, then!" the Doctor announces, turning and heading back to the TARDIS with Katy following and Rose trailing behind, still looking upset over Pete's rejection. However, Mickey doesn't immediately follow.

"Er, thing is, I'm staying," He announces, and all three of them stop, turn, and look at him in shock.

"You're doing what?" the Doctor demands.

"No, Mickey…" Katy protested.

"You can't!" Rose was aghast. However, Mickey looked perfectly serious with his intentions.

"It sort of balances out," Mickey attempted to justify his decision. "Because this world lost its Ricky, but there's me. And there's work to be done with all those Cybermen still out there." He explains, however, Rose can't accept this.

"But you can't stay."

"Rose, my gran's here," Mickey reminds her. "She's still alive. My old Gran, remember her?"

"Yeah," Rose nodded.

"She needs me," Mickey stated.

"What about me?" Rose starts tearing up, while Katy bristles; angry that Rose was being selfish once again and only thinking about herself. The Doctor puts a hand on her shoulder, and she looks up and sees the serious expression on his face as he shakes his head at her. Katy reluctantly steps down. "What if I need you?"

"Yeah, but Rose, you don't," Mickey was firm. "We had something a long time ago, but not anymore."

"Well, we'll come back," Rose decides. "We can travel anywhere. Come and see you, yeah?"

"We can't," Rose turns and looks at the Doctor with wide eyes. Katy bites her bottom lip, and turns away, upset that her best friend was leaving and never coming back. The Doctor discreetly reaches for her hand and holds it, as he continues explaining to Rose. "I told you, travel between parallel worlds is impossible. We only got here by accident. We, we fell through a crack in time. When we leave, I've got to close it. We can't ever return." Tears fall down the sisters' faces as Mickey looks at the Doctor and offers him his hand to shake.

"Doctor," He acknowledges the Doctor who takes Mickey's hand and shakes it, looking solemn.

"Take Rose's phone," the Doctor instructs. "It's got the code. Get it out there. Stop those factories. And good luck … Mickey the Idiot." He grins at Mickey who scowled playfully at the Time Lord he now considered a friend.

"Watch it!" He replied.

The Doctor turns and heads back into the TARDIS, giving the sisters a moment to say a proper goodbye to Mickey. Katy steps forward and wraps her arms around his shoulders, burying her face into them as she weeps silently. Mickey rubs her back soothingly.

"I'm gonna miss you, you know that right?" Katy tells him, and he nodded, tears threatening in his own eyes.

"Yeah," Mickey smiled. "You take care of him," He then leans forward to whisper into Katy's ear. "And I hope you open your locket soon and return to yourself."

"I hope so too. Bye, Mick. Stay outta trouble." Katy kisses him on the cheek and hugs him one more time before stepping back and heading for the TARDIS. Then it was Rose's turn. She hands him her phone.

"Thanks," He puts the phone into his jacket pocket. "We've had a laugh though, haven't we? Seen it all, been there and back. Who would have thought, me and you off the old estate, flying through the stars." Mickey smiles at Rose, who tries and fails to smile back at him.

"All those years just sitting there, imagining what we'd do one day. We never saw this, did we?" Rose croaked.

"Go on, don't miss your flight." Mickey gently pushes Rose towards the TARDIS, however, instead Rose hugs Mickey, then goes into the TARDIS, crying. Jake, who had been watching this silently, comes over and stands beside Mickey. "Jake, you want to watch this." The TARDIS dematerialises, and Jake's mouth falls open in stunned shock.

"What the hell?"

"That's the Doctor, in the TARDIS with Katy and Rose Tyler," Mickey explained, proudly.

The Tyler's Flat
Powell Estate

The TARDIS dematerialises in the living room, just as Jackie pauses in the middle of refilling the kettle, presumably about to make a cup of tea. She steps out the kitchen just as the TARDIS doors open and out steps Rose, who runs at her mother the very second she sees her.

"You're alive. Oh mum, you're alive!" Rose sobs into a bewildered Jackie's shoulder, as she looks over Rose's head at the Doctor and then at Katy who has tears still falling down her own face.

"Well, I was the last time I looked. What is it? What's happened, sweetheart?" She asks Rose, who doesn't respond. "Katy? What's wrong? Where did you go?" She asks her youngest who also doesn't respond and turns to bury her face into the Doctor's heavy brown trench coat. He answers the question instead, attempting to soothe his sobbing girlfriend at the same time.

"Far away. That was far away," he said. Jackie looked confused, then frowned when she noticed a missing person.

"Where's Mickey?"

"He's gone home," was all the Doctor said.

Pete's world
The Preachers' Van

Mickey and Jake hop back into their van, as Jake continues mulling over exactly what he had just seen moments before at Lambeth Pier. Mickey looks awkwardly at him.

"I know it's not easy with my face looking exactly like Ricky, but I'm a different man," he explained. "I'm not replacing him. But we can remember him by fighting in his name. With all those Cyber factories out there, do you think they'll be one in Paris?" He wondered.

"Yeah," Jake nodded, conceding the idea.

"Then, let's go and liberate Paris!" Mickey decided, and Jake looked at him in a mixture of amusement and bewilderment.

"What, you and me, in a van?"

"There's nothing wrong with a van," Mickey pointed out. "I once saved the universe with a big yellow truck."
