Martha stared in complete disbelief with a hint of resignation repeating him. "Rose?"

The Doctor calmed down a little. "Yes, Martha, the very same. Lost her, but in this bright big beautiful universe the impossible happens. She's here. Isn't that just invigorating?"

She scratched her head, not quite believing him. "Well, it's definitely something."

The Doctor decided her emotions as confusion so he'd explain. "Right, parallel universes. Got ahead of myself there. Do that a lot, don't I?" She nodded at him in annoyance. "Martha, every decision you make in your life there is always an alternative. You could take the elevator or the stairs, order the cake or the pie, leave home and steal a TARDIS or stay at home like a little girl. Anyways, the possibilities of the alternative happening are like an energy that creates a new universe where things change from that point."

"Oh! Like Back to the Future!"

"That was a brilliant movie, by the way! Had a very interesting conversation about oranges when I met Robert Zemeckis…" The Doctor scratched his head, seemingly lost thinking about that particular conversation, before Martha slapped him startling him. "Anyways, as you found out. Rose was trapped here forced to live a life away from me against her will. This isn't her home but rather a world where her father lives and becomes a millionaire. If I… If I had to take a wild shot in the dark, I'd say she created this one."

"What?"

The Doctor gestured nonchantly which insulted her. "Oh, a lifetime ago she saved her father but then we had to correct that because it was a fixed event. You know… all wibbly wobbly timey wimey and all that goola." The Doctor had livened up. "But the brilliant thing is I'm here! And she's here! Martha we're in the same place!" The Doctor bounded over to Martha and gave her an incredible hug, which she returned, completely happy for him.

Upon breaking the hug, he reached for her hand and took off running with Martha trying to keep up.

Between breaths, Martha yelled, "Where are we running to, Doctor? Great big world… she could be anywhere!"

The Doctor slowed, stopped and promptly slapped his head. "Ow! Oh, where, oh, where in the world is Rose Tyler?"

"Do you know where she lives?"

"She wouldn't be home. Only place she'd never be."

"So a workaholic then?"

The Doctor exclaimed in complete excitement, "Brilliant, Martha Jones! Just brilliant!" He then kissed her on the forehead. "Torchwood!"

Then just as quickly as he had stopped he took off running again with Martha struggling to keep up.

They stopped in front of a large multi-story building with guards standing in front of it resembling those that watched the king and queen in our world all stoically.

"But wait… that's… that's Torchwood? But Doctor, it's all public! Right on the boulevard not at all private or hidden!"

"Yeah, Rose told me about that. Told me she found work here too."

"Wait… how? How did you speak to her after losing her."

The Doctor seemed to let a deep hurt penetrate for a moment. "Only companion I've ever gone out of my way to say goodbye to."

"C'mon Doctor, let's go turn that frown right upside down!"

The Doctor smiled brilliantly and they walked right across the street to approach the guard.

"Where do you two think you're supposed to be going? Do you have an appointment?"

Martha asked him confusingly, "Aren't you supposed to not talk?"

The guard looked at her bewildered. "I dare say madem, why would I subject myself to such torture?"

Martha teased, "Doctor, I think your theory happened a long time before she saved her father."

The Doctor promptly nodded in annoyment and then fished in his coat for the psychic paper. "Sorry we were just going to go see an old friend, Rose Tyler." He retrieved it and showed the guard the psychic paper.

"Yes, I should say. You better go quickly before it hatches."

"Thank you sir!" They both ran inside the building and closed the doors behind them when the Doctor quickly clarified something to Martha. "He's a guard, so he hasn't received proper psychic training."

"If he had?"

"Nah, don't be thick, a guard is a guard no matter what reality."

The Doctor and Martha quickly ran up the steps in the wide entry level room they were in. The windows were large and shone copus amounts of light in making the room seem more whiter and brighter than it probably was.

"So many offices, Doctor. She could be anywhere! Maybe you should ask somebody."

"Nah, great big building. One Rose Tyler. More fun finding her ourselves."

Martha wasn't convinced and muttered something about all men being the same before stopping to ask a business suited man leaving a door, "Excuse me, Rose Tyler, where's her office?"

The man smiled as if the name triggered a memory. "Rose? Oh she's on the fourth floor in our investigations devision. Bloody brilliant that one is."

"Thanks!" Martha ran over to the Doctor. "Fourth floor, investigations. You're welcome!"

The Doctor gave her a very resigned, "Thank you" and both time travelers ran up another couple flights of stairs.

As they approached the investigations deparment they noticed it required an identification card so the Doctor quickly retrieved the psychic paper and put it against it until what felt like a minute later to Martha and probably a couple hours to the Doctor when it beeped and the doors flew open.

People in lab coats were running around in front of them in the middle of a huge investigation of some sort or at least that's what common sense would tell them was going on. "So where is she at?"

The Doctor searched with his eyes not noticing what the workers were buzzing about, not particularily caring about it at the moment, but fell in resignation when he sadly told her, "She's not here!"

"C'mon, Doctor, let's try another one, yeah?"

Behind them, the doors flew open and Martha and the Doctor's body turned to see a short blonde woman walking in with a labcoat holding an espresso that she promptly dropped on the floor in utter shock, exclaiming, "Impossible!"
