It was late Saturday night Martha was finally letting herself relax. Letting her dark hair fall delicately onto her face, she leant back in her chair and let out a modest yawn. She was almost asleep when she saw, out of the corner of her eye; a blurry figure crouched at the end of her kitchen. Frozen in fright Martha let a small gasp escape, and in reply the figure moaned. Hearing the moan Martha's doctor's instincts leapt into action, and she began creeping towards the figure. As she got closer Martha realised the figure, was actually two, one cradling the other in its arms. It was dark but Martha could make out the one crouched on the floor was a women, and as the woman reluctantly lifted her head, Martha remembered her face and spluttered "Rose?"

Seeing Martha Rose's face erupted into a tired grin. "Martha?" She asked in return for a small nod "Oh thank god. Thank god." Rose's shoulders relaxed as she breathed a sigh of relief. "Martha… you've got to help us. Please… please help us." She murmured as she slowly collapsed. Catching Rose in her arms Martha checked her vitals and carried her to a chair, before remembering the limp body fallen on the floor. It took Martha less than a minute before she realised who it was. How could she ever forget such a face? Collapsing onto the floor next to him Martha lifted his head onto her lap, and began searching for a pulse. In the end she found one heart, pumping a weak pulse. She started doing compressions on the same spot she'd done countless times before, but it didn't work, and it was only when Rose woke and told her, that she stopped.

"What do you mean that's not him?" Martha asked, her mind casting back to the fragile figure now resting up in her spare bedroom.

"That's John. John Smith." Rose told her "do you remember that time on Crucible? Do you remember the, the second Doctor?"

Martha nodded in response

"That's him. The Doctor, our Doctor, left him with me on the parallel universe."

"He didn't take you him? After all that time" Martha remembered the Doctor, her Doctor, never once looking at her, it was always Rose. When she had left she thought they would stay together, that the Doctor would finally be happy, but, obviously not.

"No" Rose replied "he left me with something even better. A human timelord. He can remember everything, you, Donna, me. But he only has one heart. He can't regenerate. And we can do the one thing he never could, grow old together." Rose glanced down, embarrassed after her small speech. "But that's not why we're here. Something happened, in the parallel earth." Rose began her tale:

"Once he, the Doctor, had left us it took a bit of getting use too. He's half Donna, half Doctor. At first I thought it was strange, I was used to the Doctor, but he persuaded me it would work, and we moved in together. It's nice having him a little human, I mean now I have someone to chat about Eastenders to!" Rose gave a little laugh "he love Eastenders, says Donna used to. Anyway, back home I work at Torchwood, I wanted him to join, but he wouldn't to start with, too many bad memories, and he wanted to be a doctor. Said he knew one once, and he wanted her to be proud of him." Martha's eyes widened and a smile crept over her face. He wanted to be like her. He wanted to say sorry. "However" Rose was oblivious to Martha's thoughts "I eventually persuaded him, and he joined working on the medical team. Doctor John Noble."

"Noble?" Martha asked

"For Donna. He became the head of his field. You know the Doctor, always wanting to be the best. At first I still called him Doctor but now these days it's John. It grew on him over the years and now I can't call anything else. But his face lights up when someone calls him doctor at work." Rose smiled thinking fondly

"Do you, do you have children?" Martha interrupted

"No, he can't. Never will be able to." Rose felt her eyes drop on Martha's sideboard where pictures of children littered its surface. Martha followed her eyes "I'm sorry." She said simply, placing her hand on Rose's.

"Don't be, we live on. You do though?"

"Yes. Three, triplets. Completely unexpected, but we love them." Martha smiled

"We?"

"Mickey and I. When the Doctor dropped us off he followed me home. I was engaged, but that didn't last long. He kept pestering me; I found red roses through my door, a golden heart necklace in my pigeonhole at work. We got married six months later. Should have been the happiest day of my life, and it was. Apart from the Siltheen attack." Martha laughed and gestured for Rose to continue.

"-At work the Doctor met these too women, Martha and Donna."

"You serious?" Martha sniggered "Us, for real?"

"Yeah. For real." Rose couldn't help laughing at Martha's expression of shock "To begin with Donna was a secretary and Martha a junior doctor, working in the labs with him. But once he was at the top Donna became his PA and Martha his top assistant in the lab. Anyway around six months ago, something started happening, the Doctor, he just suddenly became ill. Rather convenient really. t was ok at first, a little tiredness, you wouldn't notice it unless you knew he. But then, he started getting these seizures. Yesterday he fell in a coma, he was barely breathing and his heart was slowing. Today he got worse. I couldn't do anything. I had to just sit there and watch him get worse." Rose felt a tear roll over her lip "Then, Martha said something; we had told her about the parallel earth, she knew everything. She said there must be a parallel her, in the other earth, and she said maybe if we could get us to you, you could help him, find the Doctor, bring him back, and he could help my Doctor"

"But how did you get there? It's impossible to travel. He sealed them off. The Doctor sealed off the parallel universes. How? How the hell did you get here?"

"We'd been working on something at Torchwood, it's too complicated to fully explain, but we used it to transport us here. Because, Martha if we don't find the Doctor then, my Doctor, John, is going to die."

Yesterday in the Tardis

The Doctor rang his fingers of the controls, lightly flicking a switch. "So, Ponds where shall we go?"

"It's Williams." Rory reminded for the hundredth time "we married; she exchanged her name for mine, so it is Williams. W.i.l.l.i.a.m.s. It has not, not ever has been, nor never will be Ponds." He grumbled tetchily.

The Doctor took no notice and turned to Amy "Is someone on their period?" he whispered sympathetically, gesturing towards Rory

"No!" Amy muffled an indignant laugh "Doctor, that's women. We've talked about this before, remember?"

"Oh yeah" The Doctor sulked quickly busying himself with the controls, embarrassed that such a 'genius' could get something like that so wrong. "Anyway where we are going? I was thinking the ice caves of Kalmorda… or maybe the diamond caves of Janooner the second?" The Doctor flipped a leaver and suddenly the Tardis landed, crashing onto the ground. "Where are we? Kalmorda? Janooner?" The Doctor hauled back the door and peered outside. "Oh." Was all he said "how boring."

"Boring?" Amy laughed "where are we, let me see!" she pushed the Doctor playfully out the way and stared outside "Oh, we're in London! We're back home" She grinned and sniffed as the scent of vinegar surround them "I vote we get some chips. What about you Rory?" She shouted back into the Tardis only to get a muffled reply. Once Rory had appeared he too wanted chips. "Good old English chips." as he called them, and so the Doctor led the way, to as he called it, the best fish 'n' chip shop in the universe. As they crossed the road, the Doctor stopped, he started keeling over, a searing pain piercing his left heart, and slowly he staggered to the floor.
