A/N: This is my first Doctor Who fanfiction. I should mention that I am not British, so it may seem very American at times. I'll try my best. As always, reviews are always welcome.
Rose Tyler, Defender of the Earth
Rose Tyler was in the bowels of Torchwood, doing her least favorite job, filing. She was filing her report on her last mission, where she had gotten the opportunity to visit her favorite planet, Rexicoricophalivtorius. Even in this strange world, there was a whole world out there, with old haunts of Rose's and the Doctor's.
As she closed the drawer of the file, something caught her eye. She pulled out her compact laser deluxe from the back of her pants; she carried such a thing as a precaution; there had been too many attempts on her life since she had begun work at Torchwood. In this world, the weapon factory at Vilengard still existed; there was no banana grove in its place.
Rose rounded the corner slowly and saw, to her astonishment, a blue box. Not just any blue box though; this was a police public call box.
Rose could hardly believe it. She approached cautiously, weapon still drawn. Trembling, Rose reached out a hand and felt the pulsating power the Tardis always gave off.
Rose pushed on the door. It didn't budge. Rose stared at it, perplexed, before she remembered she still wore the key to the Tardis around her neck. After she shoved the key in the keyhole, she shoved again. The door still didn't budge. Rose tried the door again and again. Then it hit her. Mouth slightly open, Rose stared at the Tardis as though she had never seen it before. Because she hadn't seen it before. It was definitely a Tardis. But it wasn't her Tardis; not her Doctor.
It had never occurred to her that this world might have its own Doctor. Unsure of what to make of this revelation, Rose turned slowly away and made her way up the stairs.
Rose paused at her station, biting her lip thoughtfully. Arriving at a decision, Rose continued on to Mickey's station.
"Something wrong?" Mickey asked.
"I was downstairs," Rose began in an undertone, "filing my report on Rexicoricophalivtorius- try saying that five times fast-"
"Try saying that even once," Mickey laughed.
"Anyway," Rose continued, "something caught my eye. Guess what it was?"
"What?" Mickey asked.
"A blue police box. It was just sitting there!"
Mickey looked at Rose with pity. "Oh, Rose. I thought we were finally putting him behind us. Ever since you came to this world, you've searched everywhere for a blue box. Now you tell me you've seen one?"
Rose scowled. "I haven't gone bonkers, Mickey, if that's what you're implying. If you don't believe me then come with me."
"Alright," Mickey sighed, rising from his computer.
"Mind you, I don't think it's our Doctor," Rose said as they reached the stairwell.
"What d'you mean?" Mickey asked curiously.
"I tried my key in the slot; it didn't work," Rose explained. "We never stopped to consider that this world may have its own Doctor."
Mickey looked at Rose thoughtfully. "Well, come on," He said, taking Rose's hand. Rose grinned. Things were feeling normal again; she almost felt like she was in the "proper" world.
They reached the basement level; then the wall exploded inward. Rose screamed and she and Mickey dashed off. From their hiding place, Rose heard the voice of nightmares. "Human life-forms detected."
Suddenly, a hand grabbed Rose's free hand. "Come with me if you want to live," A somewhat familiar voice hissed. Rose tugged on Mickey's hand and allowed the mysterious hand to lead her and Mickey away from the Daleks.
It wasn't until they found themselves by the Tardis that Rose realized what was happening. She knew who the hand belonged to. Mickey and Rose were shoved inside.
Rose stood up, grinning. Then she got her first good look at this other-worldly Doctor. He looked just like her Doctor had when she first met him, complete with leather jacket.
"You're the Doctor, aren't you?" She asked.
"How on earth did you know that?" The Doctor asked, genuinely surprised.
"I'm from a parallel world; I travelled with that Doctor for a couple of years before I got trapped here," Rose explained.
"Ah," The Doctor replied.
"So, er, now what do we do?" Mickey asked.
"We take the Tardis and get as far from this place as possible," The Doctor replied, as though it was only too obvious.
"We're running away?" Rose demanded, unable to believe her ears.
"Yep. Got a problem with that?" The Doctor asked, fiddling with the controls of the Tardis.
"Yeah. You're a Time Lord. You're supposed to be fighting, not fleeing!" Rose exclaimed.
"It's what got me through the Time War," The Doctor shrugged.
"Well, it won't get you through this war," Rose snapped.
"Too late," Mickey sighed as the Tardis made its familiar whooshing noise.
Rose glared daggers at the Doctor, who avoided her gaze. The Doctor opened the doors of the Tardis. "Ah, Barcelona!" He exclaimed. "Fantastic!"
