(I would like to make a note here, that this was a roleplay between a friend of mine (Jessy) and myself. We did this story after the Doctor left Rose in Pete's World the first time, before we even knew Billie Piper was coming back into the series for a few episodes.)

When Worlds Collide: Rose & the Doctor

Over the years, the Doctor had many different companions on his travels. In the end though, they always left. Whether they left of their own will, or the Doctor failed to save them when the cold clutches of death took them, they never stayed. Each loss was a painful reminder of just how alone the Doctor really was. Everyone left. Everything died.

He'd always moved on though. He had, despite the heartache that came with it each time, grown to expect all those whom he befriended to leave him someday, and so while he never knew what the circumstances might be of their leaving, he had a little smidge of preparation built into his system. He mourned their loss, then after time moved on, though he never, ever forgot them. The one that had really struck a blow on him, though, and the pain from which would likely never fully fade from his hearts, was Rose.

He had fought to allow himself from starting to develop feelings for her, as he knew that she too, like all the others, would someday leave him, but it couldn't be stopped. She'd stolen his hearts, and they'd been crushed completely when she'd become trapped in the parallel universe. The final goodbye had been one of the most heartache inducing moments of his life, and he'd had far too many of those.

Normally his loneliness at the loss of one companion would fade away to a tolerable point upon finding a new one, but such had not been the case post-Rose. Even in his travels with Martha, he still pined for his former companion. And then, Martha had left, and Donna had come along. So much time passed, so many adventures had, and still, Rose's name was whispered in his mind with every fleeting thought. When he slept he dreamt of her. Nightmares of the destruction of his world, the loss of his people, his family, of everything now mingled with the loss of her. Yes, she was still alive, she was safe, but he'd never see her again.

He was determined to find some way to travel between the two parallel worlds without damaging anything. There HAD to be a way. It had been impossible in the first place to end up there, but he had, even if it was by accident. The idea of finding a better, safer way to get to that world again seemed impossible, but that wouldn't stop the Doctor, oh no. He liked impossible.
He thrived on impossible. The truth was that nothing ever really was truly impossible; there were only levels of how challenging a situation was. The Doctor had won in so many "impossible" circumstances; this was just one more.

Unfortunately, the time to attempt to figure out such a thing wasn't something he had much of these days. Adventures called to him, whether his assistance was asked for or he happened to fall into the situation. So many things had happened since he'd last seen Rose. So many of them pretty bloody awful. Between all of that and the constant pain of loss, he wondered if it was possible to ever feel the joy of life he once did again.

Now, after a series of some very interesting events, albeit tragic ones in the end for some part of them, he found himself back in London, 2008, as Donna wished to spend a few days at home with her family. The Doctor, whose mood was currently a bit on the broody side and not as up to going somewhere exciting just yet, had granted the request, the T.A.R.D.I.S. now safely parked behind Donna's granddad's house.

While Donna visited her family, planning to go see some friends as well, the Doctor had grown restless and wandered off on his own for a bit, keeping the phone Martha had given him, on him, so Donna could call. He'd told her he'd be back; she had seemed a little wary, and then gone on her way to see her friends and family. He wondered if she had any idea just how lucky she was to be able to do that.

He wound up heading into the city, perusing amongst various shops and some street vendors. He stopped in front of the spot where Henrik's used to stand, his hearts twinged with that old familiar heartache for a moment. He remained a minute longer, fighting back the threat of tears, and then forced himself to turn away and move on. Soon enough, his attention was caught by a fruit stand, which was selling bananas at a wonderful price of one quid per pound. Eyeing the fruity delights, he rummaged through his pockets, pretty sure he had some money from this world in there somewhere.

Finally finding the bill he was looking for, he handed it over to the fruit vendor, picking out three bananas that looked to be of just the right ripeness. A chill went through him suddenly, his senses tingling as the universe told him something was just not right. What else was new, honestly?

"Ruddy lookin' weather, innit? Sunny a moment ago, now it's lookin' to storm."

The Doctor glanced up to the fruit vendor, an older man who looked to be in his late seventies, but was still sharp as a tack. The man was currently squinting up at the sky, which caused the Doctor to look up as well, a similar frown turning down both their mouths at the sight of it.

The sky was not just dark, but was progressively getting darker. The darker it got, the worse the feeling of impending trouble within the Doctor grew. It looked like lightning clouds, but more ominous, much more ominous.

And then, just that moment, lightning struck.

Only it wasn't lightning. With regular lightning, it would either strike an empty part of the sky, or some metal pole or some unfortunate chap who happened to be passing by. This lightning hit the ground and hard, causing a huge explosion of dirt and broken pavement, sending people screaming and running. The owner of the fruit cart soon followed them, getting up and running with a departing, "Screw this, I'm off!" before running faster than any average old human the Doctor had ever seen run, or would've seen if he'd been looking.

His eyes were wide, drawn to the swirling white energy field rising up from where the lightning had struck, almost like a tear in the air. It swirled in a counter-clockwise direction, emitting strong gusts of wind. Whipping out the sonic screwdriver, the Doctor began to move closer to it, the end of the screwdriver pointed right in its direction.

By now the area was mostly evacuated, the sounds of sirens approaching the area. Another gust of wind nearly threw the Doctor off his feet, then suddenly circled back like a boomerang and hit him from the back, shoving him forward and stumbling right into the energy field, the energy doing the rest of the work in sucking him inside.

On the other side of the strange swirly energy thingie, he was thrown to the ground, a few pieces of fruit and other debris from the other side following with him. Rising quickly to his feet, the windswept Doctor looked around. Nothing had seemed to change, except that the swirly energy was gone, and there were zeppelins in the air. This meant that the impossible had happened once again: he was on the parallel Earth. Meaning something strange and likely very bad had happened.

Also meaning that Rose was here.

Despite his grave concern over what had happened, a glimmer of hope filled him. He would get to see her once again, and maybe, just maybe, she could come with him if a way back to normal Earth was restored. If it could be done, that was, with him finding a way to get himself back.

Brushing himself off, eyeing the scattered fruit on the ground, he picked up one of the bananas and began on his way to try to go find Rose, and a solution to this whole mess. Whatever had caused the rift between the two universes likely had occurred on this side, so there had to be some kind of physical indication nearby as to what it had been.

Her thoughts had been a twisted jumble over the past couple of years; wondering how The Doctor was doing, if he was alright, if he kept his promise to her. She had never gotten over getting trapped on this world, even if she had been with those she loved, her family, but that was all gone now. Her family was no more; everything had perished in her life, all because of one man-

-A man that she swore vengeance upon. He had tricked her into believing he was her Doctor and then took advantage of her, using her to get into Torchwood 3, Cardiff. When she fought him off, he retaliated by killing her family and friends, slowly, painfully, with her screaming and pleading for him to stop. He had been ruthless, relentless, malicious-yet, those events would also shape Rose into who she is now.
They shaped her into a soldier and one that wasn't going to stop until she got rid of the Torchwood Killer…

But that wasn't the worst of it, now her team was informing her that something was going down within the catacombs beneath the city. The catacombs that Torchwood, on this world, built beneath the city to contain the many weapons it captured over the years and-The Doctor of this world was behind it all. This was her chance; her chance for survival, for revenge-for justice. She wasn't going to let this slip through her fingers again, she refused.

"What do you got for me?" she asked as she strode into the Hub, removing her jacket as she moved swiftly to Tosh's side, at the computer monitor. The intruder, warning alarms were screeching overhead.

"Not much, I'm afraid. We caught the Torchwood Killer entering one of the hidden doors. When he was here he must have found the pass-codes for it…" Tosh started, but was cut off by Rose as she shook her head, some blonde hair shaking loose from the ponytail.

"No. He's got a device, a sonic screwdriver. All he would have had to figure out was where the door was located. The screwdriver would break the lock, without the codes…" Rose stopped in mid-sentence to glare up at the flashing red, warning lights, shouting, "would someone shut those bloody things off?! I can't think to hear myself speak!"

The others rushed about as Tosh worked to shut the alarms off, failing miserably. "The circuits are fried! I can't shut them off!!!" Tosh cried out, exasperated. Every single one of them had been pushed to their limits over the past few days, running on only small cat-naps here and there and Ianto's magnificent coffee.

"Fine! I'm going down there," Rose said as she spun away, slipped her coat back on and headed for the weaponry. She planned on stopping it once and for all. The Torchwood Killer would be no more, because she would make certain of it.
If this man, this "Doctor" was anything like the one she knew, then she knew who, what, he was. She knew he couldn't die, not exactly, but there are worse things than death. She'd make him wish he could die.

"You're not going by yourself! It's suicide!" Owen shouted at her.

"Watch me…" she muttered as she disappeared into the weaponry room. Nothing was going to stop her and she wasn't going to lose anyone else. She would stop him or die trying.

A few minutes later, Rose was at her SUV, shoving what looked to be some sort of futuristic rifle into the passenger seat, before climbing behind the steering wheel; the "rifle" was a type of gun, but it was a laser based alien weapon that Torchwood had uncovered about a year ago, Rose having led the team, of course. This weapon would cause the person hit by it extreme agony and if the charge was set high enough, even death; she had only used this weapon once before, to stop a crazed alien man from destroying Cardiff, and the world-the high energy charge had vaporized him, but she hadn't had much of a choice in the matter; he had seemed highly resistant to the lower settings.

Her hand on the inner frame of the open window, she started to close the door as a hand grabbed her wrist, causing her hazel eyes to glare up at the person who dared to try to stop her; it was Gwen-

"Rose, please don't go alone. You shouldn't face this demon by yourself, he could kill you."

"That's a risk I have to take, Gwen. If I don't stop him, or try to, who will? You? I know more about this man than anyone alive. Have faith, if anyone can stop him, it would be me."

"I know what you want. I know you want revenge, justice.
But is it really worth your life?"

"I give my life everyday to save this miserable planet, Gwen," she said, her voice harsher than Gwen had ever heard, "first Torchwood took my life and then he just finished what they had started. I lost everyone, including my baby brother…"

Gwen released her wrist as she saw the pain in her eyes; pain that she knew all to well. She had been there when the team had rescued Rose from the Torchwood Killer and she hadn't been in a good state of mind after that, nearly having gone insane. Some of that insanity still stuck to Rose, which is what scared her the most. Ever since she had seen Tony murdered, just a baby, barely able to crawl-that had been what broke her. Poor Tony, he had been such a sweet baby boy and it pained Gwen when she had seen Rose's family lying there in a bloodbath at Rose's tied up, sobbing form.

"Go. Do what you need to do then," Gwen said to Rose nodding. She actually had another plan; she and the rest of the team were going to track Rose's SUV and follow her. She wasn't going into this alone, no way-she was going to have her backup; the people who cared for her.

Giving a brief nod, Rose closed the door, started the engine, backed out of the parking spot and left the grounds of the complex. It was time to get the ball rolling. Unbeknownst to her, Tosh already had the tracker going and her team was trailing her a few streets behind.

Moments later Rose arrived at the coordinates of the breached door to the catacombs, throwing the SUV in park, grabbing the laser rifle and hopping out, she left the keys in the ignition, just in case of a much needed escape, a last ditch effort. As she came upon the warehouse that hid the secret entrance, one of many, she glanced around, unaware that she was being watched by the Torchwood Killer. Right hand faltering above the handle, she glanced up to see the little red, blinking dot on the security camera as it shifted its position to watch her.
I can do this. Rose, you have to do this. Remember your family.
Remember Tony… Decision made. Opening the door, she stepped into the warehouse-

"Ah, if it isn't Miss Rose Tyler, how are you doing this evening? Forlorn and melancholy, I hope. Me, on the other hand, I'm excited," came the ever familiar voice from the speakers throughout the warehouse. That voice brought back so many memories, both good and bad. Who ever knew that one face, one voice, could ever have that type of impact on anyone?

Keeping silent, refusing to respond, she kept on moving towards the entrance to the catacombs; he wouldn't be able to hear her if she said anything anyway. "Oh, come now, is that any way to treat an old friend?"

All that got from her was an eye roll. He knew so much about her past on the parallel world; about her family, life, even The Doctor and her time with him…Even that she loved him, still does. He knew because he took advantage of that love and when she had found out the truth of whom he really was…Well, let's just say it wasn't a pretty sight and she has the scars to prove it, physical, emotional and mental.

"I've got a little surprise for you, my dear," he continued to taunt over the speakers, just as she reached the entrance to the catacombs, "see, it seems that you're not alone here. I see you brought friends…"

That got a reaction out of her, just as her hand was above the handle, causing her hazel orbs to jump to the nearest camera, wide eyed.
No… Deciding she better hurry, before the team caught up with her, she grasped the door handle and then started screaming as about 1200 volts coursed through her body, eventually dropping her to the ground unconscious.

She awoke minutes later to someone, a woman, shaking her fiercely and begging her to wake up. Slowly, dazedly her eyes opened to see Gwen and Tosh kneeling over her; Gwen having been the one shaking her. Confused, she wasn't sure what had happened, but it only took a minute for the memory to rush back to her-the door handle. Wait, something wasn't right here, where are the men?

"Where…" she began to ask the women.

"We followed you," Tosh began, "and were ambushed about a block away from here. Owen and Ianto are missing. I'm afraid we…"

"Don't know where they are?" The familiar voice came as a wall seemed to come to life before their eyes. There, on the screen, were Owen and Ianto tied up to chairs and behind them-

Behind them was the Torchwood Killer, the "Doctor" of this world and what he was holding made her blood run cold as ice-her laser rifle, "Leave them alone!" Her voice surprised her, the frantic fear that laced it as she forced herself up and ran towards the screen.
"It's me you want! Leave them out of this!!"

"Now why would I want to do that, hmm? Do you have…Oh no you don't!" His shout caused her to jump, surprised and then she heard an electrical hiss of energy as something came to life behind her, causing yelps of pain and surprise from Tosh and Gwen. Spinning around, she saw the women get thrown backwards as a spark of energy passed through them and they fell to the ground unconscious, possibly even dead.

"NOOOOO!!!!" The wail emitted from her lips, even before she realized it was her. Gwen and Tosh, they weren't moving! She spun back towards the monitor, "what have you done to them?!"

"The same thing I'm going to do to these two," he replied nonchalantly as two devices descended from the ceiling above the two captured men's heads. Opening her mouth the same type of energy surged through them and she watched them screaming before they also fell unconscious or dead, leaving her gaping in surprise as she realized what it was.
It was the same type of energy that the rifle had! How had he managed to do this?

"You don't belong here. I've gotten rid of your family and now I'm going to get rid of you too. I don't want you here to ruin my plans for this world, for my domination. You've already done enough damage as it is, just by being here. And, I'm sorry to say, that while this has been fun, torturing you and all, I'm afraid it's finally come to an end."

After he was done speaking the view screen vanished and the wall slid up into the ceiling, revealing him standing there, Owen and Ianto's bodies still tied up to the chairs. Her heart was broken now and without thinking she lunged at the Torchwood Killer, hell bent on killing him with her bare hands.

"You son of a-" Her words were cut off as a hand shot out and grasped at her throat, causing her leg to shoot out and slam her booted heel into his stomach, "I'm going to kill you!!"

The man fell back, slamming into a console behind him, laughing like the madman he was. Dashing towards him his foot shot up, seemingly out of nowhere, and slammed into her side, causing her to fall sideways and land on the floor. The man rose and danced around the console, grinning that devilish grin as he peered over it at her. That grin, the one she used to love and adore, suddenly put the fear of God into her. This man took pleasure in hurting others, killing others, she had to remember that this wasn't the man she had loved.

"Goodbye Rose, and good riddance…" he said again as she rose to her feet and took a step towards the console he was standing behind. He brought his hand up, winked at her and then brought his hand down upon a button as hard, and as fast, as he could.

Suddenly a pure white beam of light shot up from the room, behind where the man was standing, her hazel eyes jerking up to follow it. Some sort of cyclone appeared, moving clockwise, causing a massive wind to whip through the room, as the entire complex began to shake and shutter, throwing her off her feet.

The man stumbled towards a corridor, muttering words that were lost upon the howling wind and then disappeared. She tried to go after him, but realized she'd die if she tried to; the foundation beneath her feet began to crack as Owen and Ianto, still strapped to their chairs, flew up into the air and into the cyclone. She made a stumbling run towards the nearest door, turning to watch in horror as the cyclone grew, expanding past the barrier that had separated her from the other women and saw them pulled up into the cyclone as well.

"Nooo!" Her wail was lost upon the howls as things began to change. Before her very eyes, the cyclone seemed to shift its direction, now moving counter-clockwise, but nothing was coming out. Raising her gaze upwards, she saw the roof was gone, but couldn't see where due to the cyclone's top. The building began to shake even more violently now, concrete falling from the walls and ceiling, the floor breaking apart even more. The place was going to collapse on her!

Giving a silent "I'm sorry & Goodbye" to her late friends, she turned on her heels and began to make a mad dash towards, what she hoped, was the entrance. She didn't want to be buried alive.
Feet racing rapidly over the ever increasing pace of the breaking floor, she dodged debris that fell from above her and then she saw it-

An open door and the warehouse beyond it and saw that it was collapsing as well; pushing herself harder, she tried to make it and then everything went black as she felt something slam down upon her and knock her to the ground, the last thing she remembered was seeing the floor, hearing the cyclonic howls and the ever-deafening crash of things falling around her, surrounding her; her last thoughts-the real Doctor.
