"Room 802."

The Doctor looked at Jack, "The night your space junk landed someone was hurt."

I looked at the solid metal door, "Who were they?"

"Let's see shall we?"

Jack stepped forward, "Step back, I can handle this."

The Doctor looked at the square blaster hole that Jack had made, "Sonic blaster, 51st century. Weapon factory of Villengard."

Jack looked almost eager, "You've been to the factories?"

"Just once."

"Well they are all gone now, all due to the explosion at the factory."

"Like I said once. Now there's a banana grove there. Bananas are good, I like them."

I stepped into the room, my eyes immediately drawn to the illustrations made by what had to be a young child.

It all came back to the boy.

A recording sounded from behind going through questions from a doctor with his patient, a young boy.

I looked at the Doctor, "I've heard that voice before. He was the boy I followed when we got here."

"Mummy?"

The song was loud now echoing in the expanses of mind. It was sad toned but with accelerating melodies as if the notes were anxious.

Tears welled up in my eyes as the Doctor paced.

"Can't you feel it?"

"Feel what?" Jack looked lost.

I looked down at the tape player not computing what I was seeing.

"Mummy, are you there?"

As the Doctor continued his tirade, I stared at the tape recorder.

"Um, Doctor?"

"I'm here." The boy's voice came again.

"It's got such a massive amount of power and I just sent him to his room." The Doctor stopped.

"I'm here. Can't you see me?"

"Doctor, behind you." Jack caught my arm as I went to grab the Doctor.

The Doctor turned around to find the boy on the other side of the room.

The boy's gas masked head shifted toward me, head tilting to the side and I could feel his honest inquiry.

"Are you my mummy?"

Jack spoke up beside me, "On my signal, head for the door."

I looked at the boy, "I'm sorry, little one. I'm not your mummy. If I were I would have never let you out of my sight."

Jack pulled me back, "Now!" and pointed a banana at the kid, while the Doctor pulled the sonic blaster from his waistband and shot a hole in the wall for us to exit through.

"Go now! Don't drop the banana!"

"Why?" Jack jumped through the hole after me.

The Doctor followed, "It's a good source of potassium."

The Doctor closed the hole after us, only for Jack to snatch the blaster back.

As the Doctor and Jack exchanged verbal jousting,

I took both their arms.

I watched as the wall broke against the force of the child's pounding on the other side.

"Run!"

Hospital doorways opened to show the other patients following after us.

"It's controlling them!" Jack yelled.

"It is them. It is every living thing in this hospital." The Doctor corrected Jack.

We ran down a hall into another only to find us trapped on all sides.

"At least I have a sonic blaster. What do you have, Doctor?" Jack clung to his blaster as if afraid the Doctor would snatch it again.

"I have a sonic..."

"What?"

"A sonic screwdriver."

"Fat luck that'll do."

"Hey!"

I sighed as they squabbled, "Boys! Brace yourselves."

I took Jack's hand holding the blaster and pressed the finger holding the trigger at the floor below our feet.

"Are you all ok?"

"Thanks for the warning."

I made my way to the wall, following the direction of the previous hallway and switched on the lights. We were in another ward, patients sat up from the beds and started moving toward us.

We moved back into another dead end.

Captain Jack pointed at the wall with his sonic but it sputtered, "I'm out of juice." There was only a closet behind us, we rushed in, the Doctor sonicing the door behind us shut.

"That should hold them for a bit."

"A wall didn't hold up against them." And they were at it again.

"Boys! Enough!" I eyed the two bickering like school children. "We should be putting our minds together to find a way out."

Jack pointed to the only window that was barred, "We are 7 floors up. If only we had more assets." Jack glared at the Doctor.

"Rose, where did you even pick him up?"

I sighed, "He saved me when I fell from the barrage balloon."

"Oh." The Doctor scratched the back of his neck.

"Yeah oh. Thank you by the way Jack." I turned only to find Jack was gone. "Rude."

Then as if to answer me the radio turned on behind us in a cabinet, "Rose, Doctor, can you hear me?"

The Doctor ran over checking behind the radio, pulling out a couple of wires here and there.

"I'm back on my ship, I used my emergency teleport. Sorry I couldn't take you, its keyed to my molecular structure. I'm working on it. Hang in there."

"How are you speaking to us?" The Doctor held up the severed wires of the radio.

"My om-com."

"The child can do the same."

"I can hear you. Coming to find you." The sweet but contrasting creepy voice of the child spoke out through the radio.

Jack spoke up, "I'll try to block out the signal. Remember this one, Marion."

MOONLIGHT SONATA began to play and the Doctor raised an eyebrow.

I raised one right back, "He was trying to con me."

The Doctor's expression didn't change and the music played on.

He went over to the window and started sonicing the concrete.

"You don't think he's going to get us, do you?"

"Wouldn't bet my life on it." His head turned to the side but didn't look back at me from where he stood by the window, "Do you?"

"My cynical side wants to say no but something else in me says to trust him." I looked down and told myself not to fidget on the only seat in the room, a wheelchair. "And he saved my life which has to count for something."

The Doctor didn't answer, but he looked back at me.

I stood up and walked toward him, placing my hand on his, "But if I had ever to pick, I would always pick you in a heartbeat."

His smile was slightly grim but he placed his other hand on mine. He cradled my hand in his before he began to raise it. He paused and turned my hand over, brow furrowing before he grabbed my other.

"Barrage balloon. You had been hanging from it high above London. Not a cut or a bruise."

"Captain Jack had some sort of nanobots, nanogenes, that healed the rope burn."

Another eyebrow raised, "Oh is it Captain Jack now?"

"What should I call him then?"

The Doctor pulled me closer, "He's not even a real captain."

"Then should I call him Mr Jack?"

A voice startled us, "Far too formal." Jack smiled over at us, "Most people notice when they've been teleported."

When I turned back to the Doctor I saw the nanogenes surrounding him and healing a small scrape on his hand.

As soon as they finished, the Doctor looked at Jack,

"We need to head down to the crash site."

"There it is. Algie is on guard duty, it must be important. I'll distract them."

Jack had barely walked over before Algie changed into a gas mask zombie.

We ran over. "The infection has become airborne. It's been accelerated."

Sirens echoed in the night air.

"Not again." I whispered.

"If the containment is airborne, then there's only a couple of hours before the end."

Jack looked spooked, "The end of what?"

"Everything! The whole human race re-written."

The doctor looked at me, "Do you hear that?"

I listened and nodded as I heard the wobbly lullaby being sung.

The Doctor disappeared following the sound and reappeared towing a young woman after him.

"I'll just open the ambulance and you'll see," Jack set off alarms instead.

The young woman pointed at the pod, "That's an ambulance?"

I gave her a nod, "It's from the stars and another world."

Wide eyes met mine.

The alarm continued.

Pounding on a nearby fence told us of the arrival of the patients.

The Doctor looked at the girl, "Nancy, how did you get in?"

"Cut the barbed wire."

The Doctor threw me his screwdriver, "I already set it up. Go weld the barbed wire back together."

Nancy pulled me towards where she came in. In the dim light I saw the clipped wire. Suddenly glad about the one year of shop I took, I leaned forward and welded the barbed wire fence back together.

Nancy seemed at the end of her tether, "Who are you? Who are you all?"

I looked at her and decided I hadn't lied about the ambulance and I wasn't going to lie about this.

"We are time travellers from the future."

"You are mad." Nancy's solemn face turned toward me, "What future?"

She looked up at the war torn skies in fear.

"Nancy, it must feel like there's no hope but all this isn't the end. London survives, I was born here in around 40 years."

"But you aren't German."

"Nope," I smiled.

When we made it back to the Chula ambulance Jack had at last opened it up, "See empty."

The Doctor scoffed, "What did you expect to see in a Chula ambulance; bandages, disinfectant?" The Doctor turned toward me, "What do you think Rose?"

I stared at the ambulance, the pieces shifting in place, my eyes widening and a sick feeling rising up my throat. "Nanogenes!"

"It wasn't empty, Captain. Millions upon millions of nanogenes resided inside it enough to rebuild a whole species. Ready to fix every scrape and bruise."

"Oh god." Jack paled.

"Except these aren't like the ones on your airship, they don't know what a human is like. Their first encounter is a dead child probably killed earlier and wearing a gas mask."

My hand covered my mouth and I glanced at Nancy whose eyes were pooling with tears.

"Life is nothing to a nanogene. They used him as a blueprint, as the only human example they are given. So they patch him up the best they can but they don't know what's skin and gas mask. Then off they go because now they think they know what humans should look like so they go off to fix all."

Nancy's cheeks were wet with the tears now.

I wasn't sure if she'd accept it but I offered my arm to her and in a moment reminiscent of the child she wrapped her arms around my middle, her head bowed against my shoulder and bawled.

The Doctor continued the anger clouding his features and his gaze zeroed on Jack.

"They won't stop. Nothing can stop it. They are all going to be made into one terrified child looking for his mother."

The gas masked people sobbed out, "Mummy? Mummy?"

"Oh and that's not all, for this is no ordinary ambulance. This is the Chula battle ambulance. They've been programmed, ready for battle. All that strength in the hands of a hysterical four year old looking for his mummy."

Jack looked at the groups massing on the edges of the fence not going any further. "Why won't they attack?"

"They are waiting for their general."

"The child?"

"Jaime." Nancy parted from my arms, wiping her tears defiantly, her chin raised high. "Not the child, he's just a little boy."

The Doctor peered at her, "I know."

"Just a little boy who wants his mummy."

Her hands became fists at her sides.

The Doctor's eyes were far away for a moment looking off into the distance, "There isn't one little boy in the universe who wouldn't tear the world apart for his mother, and this one can." There was a lost look in his eyes, like he'd once been such a child but that he was stopped from saving his own.

Nancy stepped forward, "It's all my fault."

"Mommy! Mommy!" The crowds raised their voices higher.

I looked at everyone only to catch sight of Jack fiddling with his tech brace, his eyes reached mine.

"It's volcano day, I'm sorry."

Then he was gone.

The Doctor didn't even look Jack's way instead he looked upon Nancy with a searching look, "You are older than you look. You must have been only 16 or 17, young but old enough to give birth."

"Doctor." I neared Nancy who's tears wetted her cheeks again.

"A teenage mother in the late 1930s. So you hid, you lied. You even lied to him."

Nancy nodded.

"Are you my mummy?" Jaime's voice called out again.

"He's going to keep asking," The Doctor continued, "Nancy...The future of the human race is in your hands." We both looked at him, "Trust me and tell him."

Nancy kneeled before Jaime, "Yes, I'm your mummy."

"Are you my mummy?"

"Yes I'm your mummy, I'll always be your mummy." Nancy reached out to him and brought him into her arms holding him tightly. A golden cloud of light surrounded them.

The Doctor whispered fervently, "Come on, you're smart. Check her DNA, she's his mother. That's got to be enough."

The cloud went away and the Doctor ran forward staring at the child in the gas mask.

Kneeling beside him, "Oh please, give me this day, just this one." He looks the gas mask off to reveal an adorable smiling boy beneath it. The Doctor jumped up with a shout of joy, picking up the boy and spinning him around.

I hated to interrupt a moment of such infinite joy but we were in danger still.

"Doctor, the bomb."

"Taken care of."

"How..." My mouth gaped as I looked up to find the bomb frozen above our heads caught by Jack's tractor beam. The man himself sat on top of it.

The Doctor spoke up to Jack, "Change of plans, don't need it anymore. Can you get rid of it?"

"Will do Doc." Jack grinned toward me, "Goodbye, Marion Rose."

His ship took off.

My gaze refocused on the Doctor's smile as the cloud of nanogenes surrounded him.

I let out a semi-nervous laugh, "What are you doing?"

"Software patch, sending them the upgrade."

The Doctor looked back at me and winked.

His hands sent forward the golden light nanogenes towards the other gas mask patients.

"Everyone lives, Rose! Just this once - everybody lives."

I smiled as I watched the Doctor smile so widely that his whole visage brightened, such unabashed happiness rare to see.

The Doctor had saved all from this storm.

As the Doctor came back into the TARDIS he was still shining brightly.

"The nanogenes will clean up the mess and then shut down because I told them to." He nearly skipped to the console, "Nancy and Jaime will go to Dr Constantine for help. Ditto. All and all perfect."

"Look at you beaming!" I laughed alongside him, feeling the TARDIS's joy alongside ours.

"Anything else? Let's see, ask me anything!"

"What about Jack? Will he be alright?"

The Doctor flipped a switch and the TARDIS settled on a new location. I ran to the doors as soon as I opened them I called out to the pilot, "Jack, are you coming or are you going to continue moping?"

I watched as he stepped into the TARDIS, his jaw dropped.

"Close the door will you, your ship is about to blow there will be a draft." The Doctor chimed from his side of the console.

The Doctor raised an eyebrow, "Now what?"

I bounced on my toes, "I could go for a dance."

MOONLIGHT SONATA drifted through the console room.

"Oh, Doctor, you can do better than that."

He grinned and IN THE MOOD came on.

"Fantastic!" I grinned before I offered a hand to dance to the Doctor. He took my hand pulling closer before spinning me out. We laughed joyfully as we danced around the console.

As we neared Jack, he stepped forward.

"May I cut in?"

"Oh, CJ, you already had your chance!"

"CJ?" He pouted and I threw my head back in laughter catching the Doctor's eye who smiled back at me.

"Has a nice ring to it."
