A/N: Is everyone sitting comfortably? Okay, hopefully you've read "All that's left behind." If here's what happened in very little detail.

Rose fell through the rift when the Torchwood crew opened it and ended up walking onto the TARDIS when the Doctor went to yell at Jack for opening said rift. Now Rose can't go back. Lots of accidents and a kidnap by Rogue london Torchwood later they find that Rose is growing a second heart and Jack decides to stay with the Doctor and Rose for a while. Oh and Rose also found out how the Time War actually ended. Also in a mini fic the Doctor finally learns that Rose isn;t gona die like a normal person... that pesky time vortex just loves meddling with people. It didn;t seem right that Jack couldn't die because of it but Rose remained unaffected.

Now, Martha has left the Doctor so although this takes place after Torchwood opened the rift and talks about some of the stuff he got up to in Rose's absence, from the Torchwood finale on it has nothing to do with series three! So ignore the write ups about the last three episode of the season!!!

I think that's all, it'd make more sense if you read the other story but if in doubt gimme a shout and I can explain some more.

Oh and I don't own anything, mores the pity!!!!

And so if we are all ready...


Echoes

Martha stood in the stair well drinking her coffee and staring out of the window over London. God this place could be boring sometimes. You wouldn't think it working in a hospital but after the things she's seen life on Earth was just a little too pedestrian. People passed her on the stairs, not even noticing her, paying no attention to what was around them at all and that's when she saw it. The flash of a familiar brown flashed in the corner of her eye. She wasn't sure she saw it at first, it was such a fleeting glance it could have been a trick of her mind but as she turned she saw the same colour disappearing through the door at the top of the next flight.

"Doctor?" she whispered and took off after the phantom. Her heart was pounding loudly in her ears. Had he come back for her at last? She found herself smiling at the thought and an explosion of butterflies in her stomach. He must have. Why else would he be here?

Bursting through the door she looked up and down the quiet corridor listening for the sound of his plimsolls on the lino flooring. She heard a muffled clang and curse coming from one direction. Biting back her smile she edged towards the storage room and was almost knocked flying as someone all but tumbled out, arms laden with supplies.

"Oh, sorry," he muttered breathlessly stuffing things into his pockets as he made for the stair well.

"Doctor?!"

"Nope, sorry. Don't work here. Try down the hall," he called distractedly before disappearing through the doors.

"Doctor wait!" Martha called again taking off after him. She didn't stop running until she reached the car park, four floors down. Looking around she spotted a familiar blue box and her heart leapt. Standing at the door was an unfamiliar man wearing a blue army coat.

She took off after the Doctor calling out to him across the car park.

He didn't turn round once until he reached the doors and the other man said something, pointing in Martha's direction.

"Martha! Oh am I glad to see you." The Doctor grabbed her hand and pulled her inside the TARDIS. "Come on, I need your help. Jack, get us out of here before anyone notices they've been robbed." He didn't stop to draw breath; he just kept running through the corridors until they reached a big, white, clinical looking room.

"Doctor what's going on?"

"My friend, she's hurt and I need more pairs of hands."

She felt a twinge of jealously at the fact he had another companion, let alone a female and stopped in the doorway as the Doctor rushed over to the figure in the bed.

"Its okay sweetheart, I'm back and we're going to fix you up." He pressed a light kiss to the girl's forehead as his hands frantically started throwing things out of his pockets onto the table at his side. "Martha? A little help please!"

She couldn't help it, she was dumbstruck. She's never seen the Doctor like that before. 'Looks like he finally got over Rose.' She sighed to herself and crossed over to the bed.

"Sweetheart this is Martha. You remember me telling you about Martha. She's going to help us. Martha, this is Rose."

XxXxX

Martha stood staring down at the blond girl for a moment. 'How could this be Rose? She was meant to be gone. Forever.'

"Right," the Doctor shrugged out of his jacket. "Martha, I need you to start cleaning up her side okay while I work on her head. Go on." He threw cotton and saline solution at her and directed her to the other side of the bed.

"She needs to be in the hospital," she told him quietly seeing the nasty gash on her side.

"No go. She wouldn't last two minutes once they get their hands on her," he told her, pressing a stethoscope to one side of Rose's chest and then the other.

"You'd hear it better in the middle," she muttered.

"That works on single hearted folk. When there's more than one the middle is the last place you listen to."

Martha froze and opened her mouth to speak but the Doctor shushed her before she had the chance, staring intently at Rose. He pressed his fingers to her temples and closed his eyes not moving for what seemed like ages.

"Rose?" he whispered finally in her ear, his eyes watching hers. A smile tugged at the corner of his lips as Rose's eyelids began to flutter and she took a deep breath.

Rolling her head towards the warmth of the Doctor's breath she smiled lightly as she opened her eye's to look into his.

"Hello," he grinned. "Now what have I always said about wandering off?"

Rose shrugged lightly.

Martha cleared her throat, feeling more than a little uncomfortable about witnessing the scene before her.

"You scared me then," he chastised as if he hadn't heard Martha at all.

"Sorry."

He was about to say something else when the TARDIS gave a violent jerk and threw them off balance.

"JACK! What the hell is he doing?" he growled. "Stay here!" he told Rose pointedly. "Don't let her go anywhere for at least ten minutes," he said to Martha darting out of the door.

"Hello." Rose smiled at Martha. "Sorry, didn't notice you there for a moment." She blinked a few times, trying to clear her head. "I'm Rose."

"So he said. Martha Jones."

"I know. I've heard a lot about you Martha Jones." Rose, slid off the bed and took the cotton from the stunned medical student's hand.

"Have you?"

"Yep. Should be honoured. He never spoke about any of his old companions last time I travelled with him. Well, not until we bumped into one of them."

"Oh" was all Martha could say.

"You okay?" Rose asked, hissing as her side stung from antiseptic.

Shaking herself from her trance, Martha rushed to Rose's side and began bandaging up her waist.

"What happened anyway?" she asked.

"I wandered off." Rose giggled.

"Wandered off what? A cliff?"

"Pretty much. We were messing around and I slipped and fell."

"Ouch. What was the head thing about? I've seen him slip into people's minds before but he was like that for ages just now."

"Yeah, he was scrabbling around trying to see if there was anything wrong. He sedated me when he brought me back on board. He was checking I was okay before bringing me round again. At least that's what he was saying up here," she tapped her temple. "Although, between you and me I think he just likes to be nosey." Rose winked at Martha and gave her a smile.

Martha gave a small smile back but yelped as the TARDIS practically threw them across the room.

"What has Jack been doing?!" Rose gasped, biting her lip as her side pained her.

"Who's Jack?" Martha asked, helping Rose back to her feet.

"An old friend who loves to get his hands dirty. Annoys the hell out of the Doctor."

"Sounds like a fun guy."

"Oh he is. And as much as the Doctor moans, he loves him really. Come on, lets find out what they're up to."

The TARDIS rumbled and shook as they made their way along the corridor.

"I've never felt her behave like this before," Martha said holding onto Rose as Rose held on to the wall for support.

"Me neither. I don't like it, something is seriously wrong with her."

XxXxX

"Jack, pull that lever. No the other one. Right now pump the one next to it like our lives depend on it."

"Doc, it's not working. She's going to overload if we can't solve this."

"Doctor?" Martha's voice came from the doorway.

"I told you to stay with Rose," he shouted, not even looking up from the monitor.

"I did," she called back defensively.

This time he looked up and saw Rose gripping onto the doorframe. "What are you doing here?" He was at her side in an instant, hugging her tightly.

"Uh, Doc. We still have a problem here," Jack interrupted.

'Never waste time with a hug.' Those words rang through Martha's head as she watched him grip Rose as if his life depended on it.

"Later," Rose whispered in his ear, kissing his cheek.

"Right." He nodded and guided her to the jump seats. "Strap in," he told her "you too, Martha. This is going to be uncomfortable. Jack, we're going to have to fuse her. Force her to make an emergency landing then work our way backwards to find the problem."

"Wont that hurt her?" Rose asked.

"Yes but hopefully it won't be so bad that I can't fix it."

"And what if you can't fix it? What then?" Martha asked.

"Then I get domestic," he said grimly.

"What happens if you don't fuse her?"

"Then she rips herself apart in the middle of the time vortex, taking us with her."

"Wow, not even really an option of riding it out then?" Jack said, looking intently at the Doctor.

"Not a chance. Oh, Martha Jones, Jack Harkness. Jack Harkness, Martha Jones." The Doctor tried to keep his balance as he stepped down into the engineering pit under the control panel.

"Captain Jack Harkness," he corrected.

Rose and the Doctor both coughed something that sounded dangerously like 'Sparrow' as he said his surname and Martha held back a smile at the friendly tease.

"Jack, grab a-hold of something!" the Doctor yelled.

"What are you doing?"

"Just do it!"

Jack stumbled back and wrapped his arms around the rail and waited.

The TARDIS jerked and stuttered, shaking so hard that parts started to come loose, falling all around them.

The Doctor yelled as a flash came from under the panelling.

"Theta?!" Rose yelled, trying to see into the pit.

There was another flash and the TARDIS fell dark, only some strip lighting illuminating the floor, casting strange shadows, up the walls. The room seemed to flip over and over as if it was rolling down a hill top over bottom.

It was only by the grace of God that Jack managed to keep his grip on the rail, locking his legs round the lower rail, pinning himself to it.

As they rolled to a stop the three rushed to the pit.

"Doctor? You okay?"

"Urgh." Came a reply and they all breathed a sigh of relief. "I never thought I'd feel travel sick on my own ship!" Shakily the Doctor got to his feet and clamped a hand to his head.

"Come on." Jack held out his hand to help the Doctor out.

"Everyone okay?"

"We're fine, a little battered bruised but otherwise fine."

"What about you?" Rose reached a hand up to cup his cheek.

"My head hurts," he pouted.

She pulled his hand from his head and saw a gash on his temple.

"So what now?" Jack asked peering through the darkness at the control panel.

"I have to go and reboot her."

"Okay, how do we do that?"

"I'm going to need Rose, which means I've got to fix you up first." Taking Rose by the hand he led her back to the infirmary and sat her on the table. Using the sonic screwdriver as a torch he rummaged through one of the cupboards.

"What are you looking for?" Martha asked, watching the progress of the blue searchlight flit from cupboard to cupboard and drawer to drawer.

"Aha!" he cheered triumphantly. Shaking the tube it began to glow a golden yellow.

"Nanogenes? Where the hell did you get those?" Jack asked, "I haven't seen those since the 1940's."

"I found them in one of the storage rooms a few months back. The number of times I could have used these over the past few years. Still, at least now it means I can do this." The Doctor moved over to Rose and lifted her shirt up to her chin. If it hadn't been so dark she might have blushed.

"No point in using them all," he told them, lifting only one side of the stopper. A small, golden wisp of the nanogenes seeped out and went to work, buzzing around Rose's head and sides, healing any wounds it could find. Some found the cut on the Doctor's temple and set about fixing him up, all bumps and bruises soon fading into insignificance.

"So what's the plan?" Rose asked.

"Jack, take Martha to the control room, I need you to redirect the power from the backup generator powering the strip lights to the control panel monitor; Rose and I will go to the engine room and fix the fuse."

"But I don't know anything about engines," Rose told him

"And isn't everything in the control room?" Jack asked feeling a little lost.

"Not everything that keeps the TARDIS running is in the control room. The heart and the brain are in the main control room, everything else, including what we need is down in the bowels, in the second control room. And I need Rose to help me heal her."

"How?"

"I need you to act as an amplifier. It'll be easier to explain once we're there. You two, head back to the control room. Hopefully I'll be able to boost the signal from the cameras to the monitor and you'll be able to keep an eye out for anything that might go wrong. Rose, at any time you can back out. I can do this alone."

"But it's easier with two, right?"

"Yeah."

"And safer?"

"Yeah."

"Then I'm coming and I'm doing it, whatever it takes. This is my home too. She's part of me now."

"That's why I know you can help fix her. Lets get moving."

XxXxX


Next Time:

"What happened to them?" Martha looked Rose over, seeing a burn on her temple.

"Not a clue. That's the thing about the Doc, always plays things close to his chest. But then you'd know all about that." He smiled at her softly before turning his attention back to the Doctor. "Come on buddy. Wakey wakey. Rose

needs you."

The Doctor's eyes snapped open as he drew in a deep breath.

"Never fails," Jack chuckled.

"What never fails?" he panted.

"Mention Rose needs you and you jump to it."

Coming soon

"The organic matter has completely perished. It's no use what-so-ever. Question is; why are they all here?"

"And who's playing around with them?" Martha pointed out. "When we were here before we heard noises, drills and clanging."

The Doctor visibly paled, eyes darting around the warehouse. If anyone ever succeeded in reanimating the organic matter….he shuddered at the thought. "Well it's all silent now."

"Not quite, something's slithering around in here, Doc," Jack said, pulling out his weapon.
