A/N: I'm mad at myself for not being able to keep up a normal updating schedule. It's not that I don't have the chapters written, it's that I just don't have the time to open the computer and post the chapters...

Anyway, here's the new chapter, tell me what you think about it :)

"What you doing?" Rose asked some time later, looking at the Doctor as the alien pointed his screwdriver at the window.

"Trying to set up a resonation pattern in the concrete, loosen the bars," the Doctor replied.

"You don't think he's coming back, do ya?"

"Wouldn't bet my life," he muttered.

"I would," Eva said, making the Doctor stop and look at her.

"Well, you shouldn't," he bit out.

"Why don't you trust him?" Rose questioned.

"Why do you?" he retorted.

"Saved my life," Rose shrugged. "Bloke-wise, that's up there with flossing."

"He's a good man, Doctor," Eva said. "You just need to let yourself see it."

"I trust him cos he's like you," Rose added. "Except with dating and dancing."

The Doctor looked her way for a moment before rolling his eyes and turning back to the window.

"What?" Rose asked.

"You just assume I'm..." he trailed away.

"What?"

"You just assume I don't... dance," the Doctor finished lamely.

"What?" Rose asked. "Are you telling me you do dance?"

"Nine hundred years old, me," the Doctor said. "Been dating Eva for about half that time. I've been around. I think you can assume at some point I've danced."

"You?" Rose asked in disbelief.

"Problem?"

"Doesn't the universe implode or something if you dance?" she questioned.

"Well, I've got the moves and I took Evie a couple times, but I wouldn't wanna boast."

"Did you now?" Eva asked, standing up. "Prove it."

"Evie, I'm..." the Doctor muttered. "I'm trying to resonate concrete."

"You don't need to," Eva shrugged. "Jack will be back. He'll get us out. And you got a point to prove."

"Go on," Rose prompted, turning up the volume. "The world doesn't end cos the Doctor dances."

The Doctor rolled his eyes, turning to Eva.

"May I have this dance?" he asked.

"Always the gentleman," Eva smiled. "Of course."

She took his hand, leading him to the middle of the room where he put his free hand on her waist and she put hers on his shoulder.

"So," he started. "A month and a half. What did you do?"

"I found Nancy on my second day in," Eva replied, smiling as the Doctor barely moved around. "I knew it was only a matter of time before you arrived, so I stuck with her."

"And Ricky?"

"First night here," Eva said. "The alarm started and he was frozen. We hid together."

"You two seemed close," the Doctor commented.

"We are," Eva said, determined not to use past tense when referring to the young boy she all but adopted as a younger brother. "A night hiding inside a crypt below a Cathedral filled with dead bodies can do that to you." She paused for a moment, resting her head on his shoulder before adding, "I told him of you."

"Did you?" the Doctor asked, surprised. "What did you say?"

"I told him about a man who could never die," Eva explained. "He lived for hundreds and hundreds of years, and was the last of his kind. He travelled from far away to further away, and no matter where he reached, he helped people. Saved them."

"I don't save everyone," the Doctor reminded her.

"But you save everyone you can," Eva told him. "And that's what matters." Again, there was a short pause before she spoke. "You should be nicer to Captain Jack."

"We're calling him Captain Jack now?" the Doctor muttered, backing slightly away from her.

"Well, his name's Jack, and he's a captain," Eva retorted.

"He's not really a captain, Eva," the Doctor bit out.

"Yes, he is," Eva said. "I don't think he is, yet, but he is. You can keep dancing, you know," she added.

"If ever he was a captain he's been defrocked," the Doctor retorted.

"Whatever you say," Eva said with a fond smile. "Dumbo."

"Actually I quit," Jack said, making the Doctor jump away from Eva and look at where the captain stood next to Rose, eyeing the couple. "Nobody takes my frock. Most people notice when they've been teleported," he added, winking at Eva. "You guys are so sweet. Sorry about the delay. Had to take the nav-com off-line to override the teleport security."

"You can spend ten minutes overriding your own protocols?" the Doctor asked. "Maybe you should remember whose ship it is!"

"Oh, I do," Jack retorted with a sigh. "She was gorgeous. Like I told her, be back in five minutes."

He went back to the pilot's seat and the Doctor looked around as Eva leaned against a wall.

"This is a Chula ship," the Time Lord stated.

"Yeah, just like that medical transporter," Jack informed him. "Only this one is dangerous."

The Doctor clicked his hand, and nanogenes appeared around his hand.

"They're what fixed up my hands up," Rose said. "Jack called them, um..."

"Nanogenes," Eva supplied.

"Nanogenes, yeah," Rose nodded.

"Subatomic robots," the Doctor said. "There's millions of them in here. See?" he asked, turning his hand around. "Burned my hand on the console when we landed. All better now. They activate when the bulkhead's sealed, check you out for damage, fix any physical flaws." He waved his hand, making them disappear, and looked at Eva thoughtfully for a moment. "Remind you to check you for them later," he said.

"Nanogenes?" Eva asked. "You think that would be it?"

"Wouldn't hurt to be sure," the Doctor shrugged, turning back to Jack. "Take us to the crash site. I need to see your space junk."

"Soon as I get the nav-com back on line," Jack said. "Make yourselves comfortable." He smiled at Eva's direction. "Carry on with whatever it was you were doing."

"We were talking about dancing," the Doctor said quickly.

"It didn't look like talking," Jack teased.

"Didn't feel like dancing," Eva replied. The Doctor huffed and she smiled, moving closer to him. "When did you take me dancing?" she asked.

"A couple of times," the Doctor said. "First time was with Nosey, but I don't think he counts, Scarfy, too, once or twice… doesn't count, either, and the time after that was with Shorty."

"Shorty?" Eva repeated.

"Body... seven, I think it was?" the Doctor shrugged. "Only one to be shorter than you."

"Haven't met this one yet," Eva told him.

"Oh," the Doctor said, surprised. "You're a young one."

"Is that a problem?"

"Not at all," the Doctor replied. "It just means you have more experiences with me to have."

Rose rolled her eyes at the two, turning to look at Jack.

"So you used to be a Time Agent, and now you're trying to con 'em?" she asked.

"If it makes me sound any better, it's not for the money," Jack said.

"For what?"

"Woke up one morning when I was still working for them," Jack said. "Found they'd stolen two years of my memories. I'd like them back."

"They stole your memories?" Rose asked.

"Two years of my life," Jack said. "No idea what I did. Your friend over there doesn't trust me," he said, nodding at the Doctor's direction. "And for all I know, he's right not to."

"He isn't," Eva said. "I trust you, and that should be enough for him."

"About that," Jack said, turning to look at her. "Why do you trust me?"

"Spoilers," Eva winked.

"I knew a girl who used to say that," Jack said. "Got a killer body..."

"Hair that never ends?" Eva asked, smiling.

"Lethal with a gun?" Jack retorted.

"And a hallucinogenic lipstick!" Eva said. "Oh, I know her parents."

"Do you?"

"Been to the wedding."

"Ahem?" the Doctor asked, bringing the attention back to him.

"Right," Jack nodded. "We're good to go! The crash site?"

The Doctor nodded, and Jack turned back, flying the ship away.

EMH

Jack parked his ship, and the four time travellers walked out, heading in the direction of the bomb site. The Doctor made sure to have Eva's hand in his at all times, keeping her close while sending dirty looks in Jack's direction.

"Is everything okay?" she asked him, quietly enough so that the other two won't hear.

"Yes," he replied, just a bit too quickly. "Why wouldn't it be?"

"Because you're scowling," Eva replied.

"Well, there it is," Jack declared before the Doctor could respond, oblivious to the conversation that took place behind him. "Hey, they've got Algy on duty. Must be important."

"We've gotta get past," the Doctor stated.

"Are the words 'distract the guard' heading in my general direction?" Rose asked, a small smile climbing unto her features.

"I don't think that'd be such a good idea," Jack said with a smirk. "Don't worry, I can handle it. I've got to know Algy quite well, since I've been in town."

Eva's face echoed the smile on Jack's. "I don't think you're his type," she summed it up, making Rose's eyes widen.

"I'll distract him," Jack said, heading forwards. "Don't wait up!"

"Relax," the Doctor said in response to the glance Rose sent his way. "He's a 51st-century guy. He's just a bit more flexible when it comes to dancing."

"How flexible?" Rose questioned.

"By his time, you lot are spread out across half the galaxy," the Doctor explained.

"Meaning?"

"So many species, so little time," Eva replied in a singsong voice.

"That's what we do when we get out there?" Rose questioned. "That's our mission? We seek new life and... and..."

"Dance!"

The trio watched as Jack walked right to Algy, a confident smile on his face. They stared as Algy fell to the ground and Jack stared, and started running towards them when a gas mask came out of Algy's mouth.

"Stay back!" the Doctor called, running towards him.

"You men, stay away!" Jack told the other soldiers.

"The effect's becoming airborne," the Doctor said. "Accelerating."

"What's keeping us safe?" Rose questioned.

"Nothing," Eva said, her head shooting up at the sound of alarms.

"Ah, here they come again," Jack muttered. "All we need!"

"Didn't you say a bomb was gonna land here?" Rose asked.

"Never mind about that," the Doctor said. "If the contaminant's airborne now, there's hours left."

"Till what?" Jack questioned.

"Till nothing," the Doctor said darkly. "Forever, for the entire human race, and can anyone else hear singing?"

"Oh, no," Eva muttered. "Nancy... I totally forgot. Screwdriver!" she told the Doctor. "Give me your screwdriver."

The Doctor quickly complied, a confused look on his face, and Eva took off towards the office where Nancy sat, singing Hush-a-Bye Baby to one of the guards that were transformed into... whatever these things were. When she saw Eva, she marked at her handcuffs and Eva nodded, kneeling next to her.

"Point and think," she muttered to herself as she aimed the screwdriver at the cuffs. "Point and think."

The cuffs' lock opened and Eva let out a breath as she dragged Nancy out of the cabin and pulled her into a hug.

"Oh, thank god you're okay," she muttered.

"Same here," Nancy said, holding the other woman. "The kids told me... about what happened to Ricky."

"It's okay," Eva said. "The Doctor will fix this. And he'll fix Jamie, too."

"Hello there," Jack said, walking towards them. "Care to introduce?"

"Not now," the Doctor said curtly. "We need to solve the problem you created."

EMH

"You see?" Jack said as they stood next to the wrecks of the ship he tried to sell. "Just an ambulance!"

"That's an ambulance?" Nancy questioned, staying close to Eva.

"Of a sort," Eva shrugged, unsure how to explain it to her.

"They've been trying to get in," Jack muttered, looking at it.

"Of course they have," the Doctor snorted. "They think they've got their hands on Hitler's secret weapon. What are you doing?" he asked when he saw Jack starting to work on the ship.

"When you see this thing is empty you'll know I had nothing to do with it," Jack said, just as sparks came out.

"Oh!" Rose called in surprise.

"Didn't happen last time," Jack said worriedly.

"It hadn't crashed last time," the Doctor bit out. "There'll be emergency protocols."

"Doctor, what is that?" Rose asked, stepping forwards before turning around at the sound of movement behind her. "Doctor!"

"Captain, secure those gates," the Doctor ordered.

"Why?"

"Just do it!" the Doctor called out. "Nancy, how did you get in here?"

"Cut the wire," Nancy replied.

"Show me where," Eva said. "I still have the sonic."

"Setting 2428-D!"

"I'm not going to remember that, Dumbo!" Eva called as she and Nancy ran. "My way is simpler!"

The two young women reached the fence and Eva took a deep breath as she pointed the screwdriver at the wire.

"Pont and think," she muttered as Nancy held together every two parts of wire that were supposed to be held together. "Point and think."

"Who are you?" Nancy asked when she saw the wire reattach. "Who are any of you?"

"It's... It's complicated," Eva sighed.

"You showed up out of nowhere two months ago," Nancy said. "There's a tube out there and you call it an ambulance. People are running round with gas mask heads calling for their mummies, the sky's full of bombs. Do you really think anything's not complicated?"

Eva sighed, not looking at Nancy as she spoke.

"Remember how I knew where the big bombs will drop?" she asked. "And where are the best places to get food... It's because I'm from the future. All of us are. We're time travellers."

"Mad, you are!" Nancy muttered.

"The Doctor has a time travel machine," Eva went on. "Really," she added at the look of disbelief on Nancy's face.

"It's not that," Nancy said, shaking her head. "All right, you got a time travel machine, I'll believe ya. Believe anything, me... But what future?"

Eva smiled softly. "I grew up in Careby," she said. "That's about two hours' train ride up north from here. It was also in the early 21st century." Nancy's eyes widened and Eva went on. "Rose – that's the blonde – she was born here, in London, in 1986."

"But..." Nancy started. "But you're not..."

"German?" Eva asked with a small smile. "They don't win, Nancy. I really shouldn't tell you that," she said as she reattached the last pieces of wire, "But guess what? You win."

"We win?" Nancy asked in disbelief.

"Damn right," Eva nodded. "Come on, we should go back," she added, looking behind her shoulder.

"It's empty," the two heard Jack say, finally opening the ship. "Look at it."

"What do you expect in a Chula Medical Transporter?" the Doctor asked, crossing his arms and looking at Jack. "Bandages? Cough drops? Rose?" he asked when the Captain hadn't replied.

"I dunno," Rose muttered.

"Yes, you do," Eva said, marking at her hand.

"Nanogenes!" Rose said in understanding.

"It wasn't empty, Captain," the Doctor said, sending the other male a look of disdain. "There were enough nanogenes in there to rebuild a species."

"Oh, God," Jack muttered.

"Getting it now, are we?" the Doctor bit out. "When the ship crashes, the nanogenes escape. Billions upon billions of them. Ready to fix all the cuts and bruises in the whole world. But what they find first is a dead child." Eva reached out, grasping Nancy's hand. "Probably killed earlier that night. And wearing a gas mask."

"And they brought him back to life?" Rose questioned. "They can do that?"

"What's life?" the Doctor questioned. "Life's easy. A quirk of matter. Nature's way of keeping meat fresh. Nothing to a Nanogene – heck, Eva does it about once a week."

"Oi!" Eva called out.

"One problem though," the Doctor went on, ignoring her. "These nanogenes, they're not like the ones on your ship. This lot have never seen a human being before. Don't know what a human being's supposed to look like. All they've got to go on is one little body, and there's not a lot left. But they carry right on, they do what they're programmed to do – they patch it up. Can't tell what's gas mask and what's skull but they do their best. Then off they fly, off they go, work to be done! Cos you see," he said, "Now they think they know what people should look like. And it's time to fix all the rest. And they won't ever stop. They won't ever, ever stop."

"Doctor," Eva said warningly.

"The entire human race is gonna be torn down and rebuilt in the form of one terrified child, looking for its mother," the Doctor called out. "And nothing in the world can stop it!"

"Doctor!" Eva called out angrily, glancing at Nancy from the corner of her eye. The other woman was trying to hold back tears, and Eva pulled her close. "Stop it."

"I didn't know," Jack muttered, obviously ashamed of his actions.

The Doctor didn't spare him more than a look of disapproval before kneeling next to the ship. Rose made a move to get closer to him, but Eva shook her head, marking at Jack who clearly needed comfort right now.

"Eva?" Nancy asked, and Eva turned around to see people approaching.

"Mummy, Mummy, Mummy, Mummy."

"Doctor," Eva muttered, and the Doctor looked up for less than a second before looking back at the ship.

"The ship thinks it's under attack," he said. "It's calling the troops. Standard protocol."

"But the gas-mask people aren't troops!" Rose said.

"They are now," Eva said.

"This is a battlefield ambulance," the Doctor explained. "The nanogenes don't just fix you up, they get you ready for the front line. Equip you, programme you..."

"That's why the Child's so strong?" Rose questioned. "Why it could do that phoning thing?"

"It's a fully-equipped Chula Warrior, yes," the Doctor replied. "All that weapons tech in the hands of a hysterical four-year-old, looking for his Mummy and now there's an army of them."

"Mummy, Mummy, Mummy!"

"Why don't they attack?" Jack asked.

"Good little soldiers," the Doctor bit out. "Waiting for their commander."

"The Child!" Jack said in realization.

"Jamie."
