The four of stood outside the TARDIS while the Doctor started Des up. Rose was all packed up and ready to go.

"Have you got everything?" Mum asked Rose.

"I've got everything, don't worry." Rose told her.

"Be careful." Mum told the both of us and pulled us into a hug.

"You got to call Mo about that —" Rose started but mum interrupted her.

"Oh, never mind Mo. . ." Mum said.

"Okay, I'm going now. I love you!" Rose kissed mum on the cheek.

"I love you." Mum returned and Rose walked into the TARDIS. I hugged mum again and gave her a kiss too.

"Love you, mum." I told her. She gave me kiss on the forehead.

"Love you too, Jessa." I went over to Mickey and gave him a hug.

"Bye." He whispered.

"Bye." I returned and walk into the TARDIS with a bounce in my step and a smile on my face. I close the door behind me. The Doctor looks over, noticing me and we beam at each other. The Doctor pulls a lever with extra vigour. The Doctor and I were both operating the controls while Rose was seating in the chair close by.

"So, where are we going?" She asked. The Doctor looked over to her, grinning.

"Further than we've ever gone before." He said, Rose grins back. I shot a look between them with a light frown on my lips. When Des finally landed, we step out onto a windy stretch of grass. I watch Rose's mouth drop open in amazement. "It's the year five billion and twenty three . . . we're in the galaxy M87, and this . . . this is New Earth." We looked upon a futuristic city, with flying vehicles zooming to and fro.

"That's just . . . that's —" Rose burst out laughing in wonder.

"Not bad. Not bad at all!" The Doctor said, nodding.

"I'll never get used to this." I told him with a bright smile which he returned. Rose begins to jump up and down excitedly.

"Different ground beneath my feet! Different sky . . .! What's that smell?" The Doctor bends down and pulls some grass up. He shows it to us.

"Apple grass." He said.

"Apple grass. . .!" She exclaimed. I let out a few chuckles.

"Yeah, yeah!" The Doctor beamed. I take the grass out of his hand and look at it closer.

"It's beautiful." I gaze up at the Doctor with a smile. "I love this, travelling with you. I love it." I link my arm through his.

"Me too." I laugh and the Doctor grins. He grabs my hand and we dash off. "Come on!" He yelled back to Rose. The Doctor takes his coat off and drapes it on the ground, holding his arm out for me to sit on it. While I sit down on his coat, the Doctor and Rose sprawl down on either side of me on the grass.

"So, the year five billion — the sun expands, the Earth gets roasted." The Doctor said.

"That was our first date." I smiled. The Doctor leans back to look at me.

"We had chips!" We let out a giggle. "So anyway, planet gone, all rocks and dust, but the human race lives on, spread out across the stars. Soon as the Earth burns up — oh, yeah, they get all nostalgic — big revival movement . . . but find this place!" He sits up for a better look at the view. "Same size as the Earth . . . same air . . . sam orbit . . . lovely! Call goes out, the humans move in!"

"What's the city called?" Rose asked.

"New New York." The Doctor answered. We looked at him skeptically.

"New New York?" I repeated with a raised eyebrow.

"Oh, come on." Rose said.

"It is! It's the City of New New York!" He pauses, thinking. "Strictly speaking, it's the fifteenth New York since the original. So that makes it New New New New New New New New New New New New New New York." I smile down at him, reminiscing. "What?"

"You're so different." I told him.

"New New Doctor." I felt my smile falter for a moment.

"Yeah." I turn away to look at the building in the distance in thought, missing the Doctor's frown. I look over to Rose as she starts to get up.

"Can we go and visit New New York — so good they named it twice?" She asked. The Doctor and I also start to get up.

"Well — I thought we might go there first." He nods towards the large building in the distance, on the coast.

"Why? What is it?" She asked. The Doctor had trouble getting his coat on because of the wind, so I help him out.

"Some sort of hospital. Green moon on the side — that's the universal symbol for hospitals." He told us.

"Cool." I replied as I straighten his coat out.

"I got this." He pulls out his psychic paper showing it to Rose remembering that I couldn't read it. "A message on the psychic paper. Someone wants to see me." He tucks it back in his pocket.

"Hmm! And I thought we were just sight-seeing. Come on then! Let's go and by some grapes." Rose said as she links arms with him. I stare after them for a moment before catching up to them and pulled a face.

"Grapes? They're so weird though." I complained, earning a chuckle from Rose. She leans in close to the Doctor.

"Jessa hates grapes and what's the other fruit you hate?" She turns back to me.

"Pears." I replied. "They're so gross and useless. Who even likes them, anyway?" The Doctor laughs and wraps an arm around my waist.

"I completely agree with you, Jessamine." He said with a grin. "What fruit do you like?"

"Strawberries." I answered with a raised eyebrow. "Why?" The Doctor just shrugged with that grin still on his face.

"No reason." He replied as we stopped at an ATM to get credits and then bought some grapes at a fruit stall. Rose ate the grapes on our walk to the hospital, the Doctor telling us about how he dislike hospitals. We walk through the doors and into the reception.

"Bit rich coming from you." Rose said.

"I can't help it! I don't like hospitals — they give me the creeps!" He told us.

"The Pleasure Gardens will now take visitors carrying green or blue identification cards for the next fifteen minutes. Visitors are reminded that cuttings from the gardens are not permitted."

"Very smart. Not exactly NHS." I said looking around.

"No shop. I like the little shop!" I let out a half snort at the Doctor's ramblings.

"I thought this far in the future, they'd have cured everything." Rose said.

"The human race moves on, but so do the viruses. It's an ongoing war." A cat nurse walks by and nods politely to Rose, who stares at her.

"They're cats." She points. I push her hand down.

"Rose, it's rude to point and stare." I scolded her.

"Now, don't stare . . . think what you look like to them, all . . ." He looks us both up and down. "Pink and yellow. Blue and brown. That's where I'd put the shop!" He points over my shoulder. "Right there!" I roll my eyes at his behavior and follow him into the lift behind us. "Ward 26, thanks!"

"Hold on! Hold on!" Rose shouts as she rushes to the lift, but too late. The door closed right before she gets there.

"Oh, too late — we're going up." The Doctor said through the doors.

"It's all right, there's another lift." We hear her call.

"Ward 26. And watch out for the disinfectant." The Doctor calls down. I give the Doctor a look.

"Watch out for what?" She called up.

"The disinfectant!" We hear her call up again and I put a hand on the Doctor's arm.

"She'll find out." I told him.

"Commence stage one — disinfection." Green lights flash on and we're soaked in a shower of disinfectant. I jolted a bit in shock while the Doctor is perfectly calm. I laugh as the Doctor runs his hands through his hair. Soon a white powder is puffed onto us. Then a blow-dryer engages. I smile as I look over to the Doctor and see that he's enjoying the experience immensely, spreading his coat out to dry and smiling happily. I help fix the Doctor's hair before the lift doors slide open at ward 26 and we step out. One of the cat nurses leads us into the ward.

"Nice place. No shop, downstairs. I'd have a shop. Not a big one — just a shop. So people can shop." The Doctor said, looking around.

"The hospital is a place of healing." The nurse said, surprised.

"A shop does some people the world of good. Not me. Other people . . ." We start to walk, I pause slightly to stare at a completely red man.

"The Sisters of Plentitude take a lifelong vow to help. And to mend." We then pass a bed holding an extremely fat man looking as though he was about to turn to stone. By the bed is a very prim woman.

"Excuse me!" She called, indignantly. She approached us. "Members of the public may only gaze upon the Duke of Manhattan with written permission from the Senate of New New York."

"That's Petrifold Regression, right?" The Doctor asked, nodding to the Duke.

"I'm dying, sir. A lifetime of charity and abstinence. And it ends like this." I raised an eyebrow at the man.

"Any statements made by the Duke of Manhattan may not be made public without official clearance." The lady stated.

"Frau Clovis!" The Duke gasps. She rushes to his side. He grasps her hand. "I'm so weak!"

"Sister Jatt! A little privacy, please!" Clovis exclaimed, outraged. Sister Jatt leads us away.

"He'll be up and about in no time." She told us.

"I doubt it. Petrifold Regression? He's turning to stone. There won't be a cure for . . . oh . . . a thousand years? He might be up and about, but only as a statue . . ." I started to look around at the other patients while they talked to each other. I turn towards the back and let out a soft gasp. 'Jack!' I race over to him and the nurse beside him. I kneel down in front of him and rest my hands on the glass case.

"Novice Hame — if I can leave this two in your care?" I heard Sister Jatt ask.

"Oh, I think my friend got lost. Uh — Rose Tyler. Could you ask at reception?" The Doctor asked.

"Certainly, sir." I turn to Novice Hame when Jack doesn't acknowledge me.

"What's wrong with him?" I asked her.

"I'm afraid the Face of Boe's asleep. That's all he tends to do these days. Are you a friend, or . . .?" She asked.

"A very good friend. We met on Platform One. What's wrong with him?" I asked again, interrupting the Doctor.

"I'm so sorry. I thought you knew. The Face of Boe is dying." My eyes widen in horror.

"Of what?" I asked, turning back to Jack.

"Old age. The one thing we can't cure. He's thousands of years old. Some people say millions. Although, that's impossible." She told us.

"Oh, no . . . I like impossible." The Doctor kneels beside me. "I'm here. I look a bit different, but it's me . . . it's the Doctor . . ." He places a hand right next to mine on the tank. Jack lets out a sigh.

"Hope, harmony and health. Hope, harmony and health." The Doctor crosses the ward and gives Novice Hame and I a glass of water.

"That's very kind. But there's no need." Novice Hame said to him.

"You're the one working." He said as he goes to the window.

"There's not much to do. Just maintain his smoke. And I suppose I'm company. I can hear him singing, sometimes. In my mind . . . such ancient songs . . ." She trails off. I glance at her.

"Are we the only visitors?" I asked her.

"The rest of Boe-kind became extinct. Long ago. He's the only one left. Legend says that the Face of Boe has watched the universe grow old." The Doctor smiled. "There's all sorts of superstitions around him. One story says that just before his death, the Face of Boe will impart his great secret. That he will speak those words only to the ones like himself."

"What does that mean?" I asked her.

"It's just a story." She answered.

"Tell us the rest." The Doctor said.

"It's said he'll talk to the wanderers. To the man and woman without a home." I glance towards the Doctor when I recognizes ourselves in that sentence. "The lonely God and Witch." I stayed beside Jack while the Doctor went to find Rose.

"Jack?" I whispered so only he could hear. "It's Jessa. I'm here, little brother. I fulfilled my promise just like you asked." I felt a tear rolled down my cheek. "Please don't leave me." I look over to the Duke side of the room, I could hear the Duke laughing which didn't make sense. I stood up and walked over to his room. The Duke and his lady friend were drinking a glass of champagne.

"Didn't think I was going to make it!" The Doctor steps into view. "It's that man again." The Doctor smiles, scratching his ear absent-mindedly. "He's my good luck charm! Come in! Don't be shy!"

"Any friendship expressed by the Duke of Manhattan does not constitute a form of legal contract." The Doctor and I nodded.

"Winch me up." He gives the Doctor a thumbs up. Frau Clovis presses a button on a remote and the bed tilts forwards. "Ah! Look at me! No sigh of infection!"

"Champagne, sir? Miss?" A waiter asked us. I shook my head.

"No thanks. Uh . . . you had Petrifold Regression, right?" He asked the Duke.

"That being the operative word! Past tense! Completely cured." The Duke laughs joyfully.

"But that's impossible." I turn to the Doctor.

"What is it?" I asked him.

"Primitive species would accuse us of magic, but it's merely the tender application of science." Another cat nurse told us. The Doctor turned to her.

"How on Earth did you cure him?" He asked.

"How on New Earth, you might say." She repeated his statement.

"What's in that solution?" He asked, nodding to the drip.

"A simple remedy." she stated.

"Then tell me what it is." He challenged her.

"I'm sorry. Patient confidentiality. I don't believe we've met. My name is Matron Casp." She said.

"I'm the Doctor and this is Jessa." He motions to me.

"I think you'll find that we're the Doctors here." She told him as Sister Jatt walks up to the matron.

"Matron Casp — you're needed in intensive care." She told her.

"If you would excuse me." She said to us. We nodded and watch them leave.

"Something's not right." I told the Doctor.

"Your feelings acting up?" He asked, I nodded. The Doctor turns back to the nurse, this time watching them suspiciously. The Doctor puts on his glasses and starts looking at each of the patients in the ward. I look over to the elevator when the doors open revealing Rose. I stared at her as she walks out getting another bad feeling flowing from her.

"There you are! Come and look at this patient!" I'm shaken out of my thoughts as the Doctor takes my arm and shows me to the red man. The Doctor takes his glasses off. "Marcont's Disease. Should take years to recover. Two days. I've never seen anything like it — they've invented a cell washing cascade — it's amazing. Their medical science is way advanced. And this one!" He leads me to another bed sporting a completely white man.

"Pallidome Pancrosis. Kills you in ten minutes, and he's fine!" He waves cheerily to the patient. "I need to find a terminal. I've got to see how they do this." We walk off, Rose following us. "Because if they've got the best medicine in the world . . . then why's it such a secret?"

"I can't Adam and Eve it." Rose said, stopping in her walk. I turn to her confused.

"What's with the voice?" I asked her. Rose ignores me and stares up at the Doctor.

"Oh, I don't know . . . just larking about New Earth . . . New me . . ." She looks him up and down.

"Well, I can talk. New New Doctor." He grins.

"Mmm . . . aren't you just . . ." Rose suddenly pulls his face towards her and plants a smacking kiss on his lips. My eyes widen in shock and hurt while my mouth drops open in a silent gasp. When she finally pulls away, the Doctor looks extremely shocked and she's slightly breathless. "T . . . terminal's this way." She walks off, exhaling slightly. I stare at the Doctor for a moment then move to go after Rose.

"Jessamine!" The Doctor grabbed hold of my arm before I could get too far away. "It's not what you think. It didn't mean anything to me." I glanced at him then plastered a fake smile on my face.

"It's fine, Doctor. I'm just your friend nothing more." I told him then went after my sister. We finally caught up with her looking at the details of the hospital on a screen.

"Nope . . . nothing odd . . . surgery . . . post-op . . . nano-dentistry . . . no sign of a shop . . . they should have a shop." Rose walks around him to look closer at the screen.

"No, it's missing something else. When I was downstairs those Nurse/Cat/Nuns were talking about Intensive Care. Where is it . . .?" I shared a look with the Doctor then turned to Rose.

"You're right, well done." I told her.

"Why would they hide a whole department?" She asked. The Doctor takes his sonic screwdriver out of his pocket. "It's gotta be there somewhere. Search the sub-frame." I kept my facial expression neutral while I slipped my wand down to my hand. The Doctor turned his head to her.

"What if the sub-frame's locked?" He asked her.

"Try the installation protocol . . ." She answered.

"Yeah, course. Sorry. Hold on." He starts scanning the screen. He clicks his sonic screwdriver off and the entire wall moves downwards, revealing a secret corridor behind. Rose smiles and walks straight into it. The Doctor and I follow after her to keep her in our sight. "Intensive Care. Certainly looks intensive."

We go down some metal steps into Intensive Care. We find ourselves in a huge cavernous chamber, looking upon row and row of green doors. The Doctor walks along one of the rows and opens a door with his sonic screwdriver. A man, covered in boils and surrounded by smoke looks back at us.

"That's disgusting. What's wrong with him?" I stare at Rose in disgust. Who was this person standing beside me?

"I'm sorry. I'm so sorry." The Doctor said to the man, horrified. Rose holds her nose while the Doctor closes the door gently and opens another.

"What disease is that?" I asked him while we stare at the woman inside.

"All of them. Every single disease in the galaxy, they've been infected with everything." He said quietly, disgusted.

"What about us? Are we safe?" Rose asked.

"The air's sterile. Just don't touch them." The Doctor shuts the door and then leans over the railing, looking upon the rows of doors. I move after him and place a reassuring hand on his shoulder.

"How many patients are there?" She asked.

"They're not patients." I replied for the Doctor.

"But they're sick." The Doctor spun around, angry.

"They were born sick. They're meant to be sick. They exist to be sick. Lab rats. No wonder the Sisters have got a cure for everything. They've built the ultimate research laboratory. A Human farm." He spat out.

"Why don't they just die?" She questioned.

"Plague carriers. The last to go." I answered.

"It's for the greater cause." We turned around and spotted Novice Hame.

"Novice Hame. When you took your vows, did you agree to this?" The Doctor asked her.

"The Sisterhood has sworn to help." She said.

"What, by killing?" The Doctor shouted.

"But they're not real people. They're specially grown. They have no proper existence." She told him, gently.

"What's the turnover? Hm? Thousand a day? Thousand the next? Thousand the next? How many thousand? For how many years? How many?" The Doctor asked as he advanced dangerously, but I grabbed his arm to stop him getting to close and doing something he might regret later.

"Mankind needed us. They came to this planet with so many illnesses. We couldn't cope. We did try. We tried everything. We tried using clone-meat and bio-cattle . . . but the results were too slow. So the sisterhood grew its own flesh. That's all they are. Flesh." She said. I turned to her with a look of pure disgust on my face.

"These people are alive." I hissed at her.

"But think of those Humans out there . . . healthy . . . and happy, because of us." She replied. I shook my head.

"If they live because of this, then life is worthless." She stared at me for a moment.

"But who are you to decide that?" She asked. I looked to the Doctor then back to her. The Doctor took a step forward and stopped right in front of her with me right by his side.

"I'm the Doctor and she's the Mistress of Death. And if you don't like it . . . if you want to take it to a higher authority, then there isn't one. It stops with us." Rose peered over our shoulders.

"Just to confirm . . . none of the Humans in the city actually know about this?" She asked.

"We thought it best not —" I held up a hand to silence her.

"One second. I can understand the bodies and I can understand your vows." I glared at her, my green eyes flashing with hidden fury. "But there's one thing I can't understand — what have you done to my sister?"

"I don't know what you mean." Novice Hame said, confused.

"I'm being very calm. The only reason I'm being so very calm is that the brain is a delicate thing. Whatever you've done to my sister's head, I want it reversed now." I demanded, deadly quiet.

"We haven't done anything." Novice Hame repeated.

"I'm perfectly fine." Rose told me. I turned to her and stared her straight in the eyes.

"Theses people are dying, and Rose would of cared." I told her. She rolled her eyes and pouted.

"Oh, all right, clever clogs." She said.

"What's happened to you?" I asked her.

"I knew something was going on in this hospital, but I needed a body and a mind to find it out. I would have preferred your's but your sister worked alright." I glared at the person using my sister's body.

"Who are you?" I demanded. Rose moves over to whisper in my ear.

"The Last Human." I jolted back from her, eyes widen.

"Cassandra?" I asked, unpleasantly surprised.

"Wake up and smell the perfume." She takes a tube of perfume out from her shirt and skirts it in the Doctor's and mine face. I immediately keel over, unconscious. I groan as I wake up and look around, I was inside one of the Intensive Care cells. I move to the door of the cell and bang on the door.

"Cassandra! Cassandra!" I screamed out, ignoring the other banging sounds and yells. Cassandra comes to the door and quirks an eyebrow.

"No need to scream, big sis." She mocked. I let out another scream and kicked the door.

"Get out of her body, Cassandra. Right now." I hissed out, dangerously. I could feel my magic spiking.

"No, I don't think I will. Out of all the ways I thought I could kill you and only to realize you can't die? Well, this option works just fine. This one will kill you maybe not physically but emotional and mentally? Oh yes." I let out a shaky breath.

"You have no idea who you're dealing with Cassandra." I told her.

"Oh, but I do. It's all up here." She tapped Rose's forehand. "Now I'll leave this body when I've found a better and younger one. Now hushaby! It's showtime." I began to bang on the door again as she walked away.

"Cassandra! Come back here! Cassandra!" I shouted. I continued to bang on the door until it springs open. I step out of the cell looking for Rose. The Doctor rushes over to me, moving me out of the way from some infected people.

"What've you done?" The Doctor yelled towards Cassandra-Rose.

"Gave the system a shot of adrenaline, just to wake 'em up. See ya!" She runs off. I dash off after her, leaving the Doctor behind.

"Don't touch them!" I heard the Doctor call. "Whatever you do, don't touch!" Rose let out a scream as we run for our lives along the rows, all of the doors opening. We paused for a moment and watch all the zombies break out of their cells.

"Oh, my God . . ." I heard Cassandra-Rose say. I turned to her.

"What the hell have you done?" I asked her.

"It wasn't me!" She exclaimed.

"I want that body safe, Cassandra!" I yelled at her. The zombies were advancing on us.

"We've gotta go down!" The Doctor called.

"But there's thousands of them!" Rose said, scared.

"RUN! Down! Down! Go down!" We run down the stairs. The zombies followed us as we go down the stairs, arms outstretched. "Keep going! Go down!" We descended the last flight of stairs and burst through a door into a cellar. Cassandra-Rose frantically tries to operate the lifts.

"No, the lifts have closed down. That's the quarantine, nothing's moving." The Doctor, stopped.

"This way!" Rose runs the other way, with the Doctor and I on her heel. More of the infected people begin to spill out from converging corridor.

"Someone will touch him!" The Doctor begins to go back to help the man that was with Cassandra.

"Leave him! He's just a clone thing, he's only got a half life — come on!"

"Mistress!" The clone calls pitifully. Cassandra-Rose ran off in the opposite direction. I looked to the Doctor then raced after Rose to keep her in my sight.

"I'm sorry, we can't let her escape!" The Doctor called to the clone and ran after rush back to the basement, slamming the door behind us. Cassandra-Rose tries another door but seeing the zombies all clambering to get in behind it, slams it shut again.

"We're trapped! What're we going to do?" She asked, upset and scared.

"Well, for starters, you're going to leave that body." The Doctor said, angrily. Then he gestures up at the metal thing in the room with his sonic screwdriver.

"Doctor, what is that?" I asked him.

"That's a psychograft. It's banned on every civilized planet! You're compressing Rose to death." I turned to Cassandra in fear.

"Get out of my sister!" I shouted at her. She glared at me.

"I've got nowhere to go. My original skin's dead." She told us. I gave her a vicious glare.

"I don't care!" I turned to the Doctor and snatched his sonic screwdriver out of his hand and point it threateningly at her. Not even thinking about taking my wand out, it may be Cassandra right now but my baby sister was still there. "Give me my sister back, trampoline." She sneered.

"You asked for it." In a cloud of light, Cassandra leaps from Rose's body and into mine.

JTDW

Doctor's Pov

I stare on fury as Cassandra uses Jessamine's body. I point my sonic screwdriver at her, threateningly.

"Get out of her body now, Cassandra or so help me." I growled out at her. She looked up at me, Jessamine's bright green eyes give a slight eerie flash. Cassandra gave us a smirk that didn't look right on Jessamine's beautiful face.

"But what if I don't want to, Doctor?" She question while making Jessamine's voice low and husky. "Immortality is a very difficult thing to just give back." She closes her eyes and lets out a sigh of delight. "And oooooo, I can feel the power coursing through these veins. I look good, don't you think?" She asked with another smirk.

"Get out of her!" Rose shouted, causing the smirk to get wider.

"Is that a threat or an order, lil sis." She teased. Rose just gave her a glare and she turn to me. She walked over to stand in front of me. "Might as well let this sister kiss you since I let the other one do it." And with that she pulled me into a smashing kiss. After a moment she pulled back, both of us breathless. She stared at me with a thoughtful look and I raised my screwdriver at her again.

"Out. Now." I ground out through gritted teeth. She rolled her eyes and let out a huff.

"Oh, fine." She leaps out of Jessamine and into me.

JTDW

Jessa's Pov

"What . . .?" I looked around confused for a second.

"Oh, my." I snapped my head to the Doctor with wide eyes. "This is . . . different."

"Cassandra?" I asked, feeling a little awkward.

"Goodness me, I'm a man. Yum. So many parts! And hardly used . . ." She wiggles around crazily. "Ah . . ah! Two hearts! Oh, baby, I'm beating out a samba!" I rolled my eyes, exasperated.

"Get out of him, Cassandra." She runs a hand down his body.

"Ooh, he's slim. And a little bit foxy." She raises his eyebrows at me. "You've thought so too. I've been inside your head . . ." I looked away with a light blush on my face. She came closer. "You've been looking . . . you like it." She said, teasingly. The zombie people suddenly burst through the doors making us all jump.

"What do we do? What would he do? The Doctor — what the hell would he do?!" She cried, frantically. I raised an eyebrow at her, she just made the Doctor sound absolutely gay for a moment.

"Well, I'm never gonna let the Doctor forget this moment." I stated with a teasing smirk. She rolled her eyes at me. I look around and notice a ladder. "Use the ladder, we've got to go up." I told them. Cassandra shoves Rose roughly out of the way to get to the ladder first.

"Out of the way, Blondie!" The zombies come even closer. I push Rose to move faster and hurriedly follow after them. As we climbed up the ladder, I kept looking down to check to see if anyone was following us.

"If you get out of the Doctor's body, he can think of something." Rose called up to Cassandra.

"Yap yap yap . . . God, it was tedious inside your head. Hormone City." Cassandra sniped back. I let out sigh at their bickering.

"Can we not fight right —" I let out a scream as something grabs my ankle. I look down in panic and find Matron Casp. "Get off!" I shake my ankle a bit and grab tightly onto the handles of the ladder.

"All our good work! All that healing!" I rolled my eyes. "The good name of the Sisterhood — you have destroyed everything!"

"Go and play with a ball of string." Cassandra said, dismissively.

"Everywhere — disease! This is the Human World. Sickness!" A diseased hand grabs Matron Casp's ankle. She wails in pain and breaks out into boils. She releases my ankle and falls down the shaft.

"Move!" I shout up towards my sister and Cassandra. Cassandra lets out a whimper and hastily starts to climb the ladder again.

"Maximum quarantine. Divert all shuttles."

We get to the top of the ladder and find the doors are sealed.

"Now what do we do?" Cassandra asked.

"Use the sonic screwdriver." She takes it out of his pocket between his thumb and forefinger while wrinkling his nose.

"You mean this thing?" I let out a groan and nodded.

"Yes, I mean that thing." She looked down at it.

"Well, I don't know how — that Doctor's hidden away all his thoughts." I bit my lip for a second, thinking.

"Cassandra, do back into me." I told her.

"Hold on tight." She leaps back into me.

JTDW

Doctor's Pov

"Oh . . . wonderful." Cassandra sighed then looked up at me. "Open it!"

"Not 'til you get out of her." I point my screwdriver at her again.

"We need you, Doctor." Rose said but I ignored her.

"I order you to leave her!" I shouted, angrily. She leaps back into me.

JTDW

Jessa's Pov

"No matter how difficult the situation, there is no need to shout." I gave her an unimpressed look.

"Really, Cassandra?" She looked down at me.

"I can't go into you, he simply refuses — he's so rude." I rolled my eyes.

"Figure something out then, trampoline." She sent me a glare before looking down behind me in disgusted and reluctance.

"Oh, I am so gonna regret this . . ." Cassandra leaps from the Doctor's body and into a diseased woman's body. "Oh, sweet Lord . . . I look disgusting." The Doctor opens the lift doors and helps Rose out then holds a hand to me.

"Nice to have you back." I gave him a smile as I grab his hand and let him help out.

"No, you don't . . ." I let out a gasp of shock, falling to the floor as Cassandra leaps back into my body.

JTDW

Doctor's Pov

I quickly spun around when I heard Jessamine gasp followed by a thump. Her eyes were dazed as she stared into space. I let out a growl of annoyance.

"That was your last warning, Cassandra!" She just keeping staring.

"Inside her head . . . they're so alone . . . they keep reaching out, just to hold us . . . all their lives and they've never been touched." She said, quietly. My gaze soften, slightly. I hold my hand out to her, which she takes. I pull her to feet while the diseased people bang on the lift doors. We walk off, through a door that leads back to Ward 26. As we walk into the Ward, Frau Clovis brandishes a chair at us menacingly, roaring like a wild animal.

"We're safe! We're Safe! We're safe. We're clean! We're clean! Look, look —" The three of us start showing her our skin.

"Show me your skin." We all raised our arms high to show her.

"Look! Clean. Look — if we'd been touched, we'd be dead." Frau Clovis nods and puts the chair down. "So, how's it going up here? What's the status?"

"There's nothing but silence from the other wards. I think we're the only one left. And I've been trying to override the quarantine." She fiddles with a small device in her hands. "If I can trip a signal over to New New York, they can send a private executive squad."

"You can't do that. If they forced entry, they'd break quarantine." I told her.

"I am not dying in here." She stated, angrily.

"We can't let a single particle of disease get out — there is ten million people in that City, they'd all be at risk! Now, turn that off!" I shouted.

"Not if it gets me out." I give her a cold look.

"All right, fine. So I have to stop you lot as well. Suits me. Jessa. Rose. Novice Hame. Everyone! Excuse me your grace — get me intravenous solutions for every single disease. Move it!" I kept a watch on Cassandra as everyone gathers all of the solutions. I try a rope around my body and Cassandra attaches the solutions to it so they hang off me. "How's that? Will that do?"

"I don't know! Will it do for what?" I open the doors to the lift with my sonic screwdriver. "The lifts aren't working." I peer down the shaft.

"Not moving. Different thing." I step right back, ready for a running jump. "Here we go." I stick the sonic screwdriver between my teeth and run.

"But you're not going to —" I jump into the middle of the shaft and cling onto the rope. "What do you think you're doing?!"

"I'm going down!" I fix up the wench with my screwdriver. "Come on!"

"Not in a million years." She said.

"I need another pair of hands. What do you think? If you're so desperate to stay alive . . . why don't you live a little?" More zombies emerge from the quarantine.

"Seal the door!" Frau Clovis shouted. The door close, leaving Cassandra trapped with the zombies and no choice to jump into the lift shaft and onto my back with a regretful moan.

"You're completely mad. I can see why she likes you." I look away from her as my cheeks flared with a sudden heat.

"Going down!" We whizz down the shaft, screaming. We straighten ourselves out when we reach the bottom.

"Well, that's one way to lose weight." I rolled my eyes.

"Now, listen — when I say so, take hold of that lever." I point to the lever.

"There's still a quarantine down there, we can't —"

"Hold that lever!" I shout and she backs down. "I'm cooking up a cocktail. I know a bit about medicine myself." I rip the tops off the packets of each solution with my teeth and squirts them into the clear container where the disinfectant for the lift goes. "Now, that lever's going to resist. But keep it in position." I open a trapdoor on the top of the lift. "Hold onto it with everything you've got."

"What about you?" She asked.

"I've got an appointment. The Doctor is in." I drop down into the lift. I open the doors with the sonic screwdriver. Beyond, are all the infected people huddled in groups. When they see me, they start to come towards me. "I'm in here, come on!"

"Don't tell them!" Cassandra shouted.

"Pull that lever!" The infected people stagger towards the lift. "Come and get me, come on! I'm in here, come on!" They reach out to me.

"Commence stage one — disinfection."

"Hurry up, come on!" I beckon them towards me. The solution showers into the lift, soaking me. "Come on, come on." The infected people stumble into the shower and are also soaked with the medicine. "All they wanna do is pass it on. Pass it on!" I exclaimed, enthusiastically.

"Pass on what? Pass on what?!" Cassandra asked confused.

"Pass it on!" I grin manically as they become healthy. Cassandra jumps down into the lift with my help.

"What did they pass on? Did you kill them? ALL of them?" She asked.

"No. That's your way of doing things." I walk into their midst. "I'm the Doctor and I cured them." The new humans look around at their surroundings, slightly child-like. A woman comes up to me and hugs me. "That's right! Hey, hey! There we go, sweetheart! Ay? Look at him . . ." I usher her off to sit with someone. "Go on, that's it! That's it! It's a new sub-species, Cassandra!" I take a man by the shoulders and look at him.

"A brand new form of life! New Humans! Look at them, look!" I bend down to look at them with a huge smile on my face. "Grown by cats . . . kept in the dark, fed by tubes . . . but completely, completely alive!" I point at Cassandra. "You can't deny them, because you help create them." She rolls her eyes. "The human race just keeps on going. Keeps on changing. Life will out! Ha!" We walk back into the ward while the police officers swarm the hospital.

"All staff will present themselves to the officers for immediate arrest. I repeat - immediate arrest. All new life forms will be catalogued and taken into care." I watch as Novice Hame is lead away by a police officer. She catches my eye and I don't smile. "All visitors to the hospital will be required to make a statement to the NNYPD."

"The Face of Boe!" I said, suddenly remembering. 'Jessamine would probably cruse me if I forgotten.' I dash off again with Rose and Cassandra following after me. I approach the Face of Boe, who looked very much alive and well. "You were supposed to be dying." I said, smiling.

"There are better things to do today. Dying can wait."

"Oh, I hate telepathy. Just what I need, a head full of big face." Cassandra stated, rudely.

"Shh!" I hissed at her.

"I have grown tired with the universe, Doctor, but you have taught me to look at it anew." I kneel before him.

"There are legends you know, saying that you're millions of years old." I told him.

"There are? That would be impossible." He laughed slightly.

"Wouldn't it just? I got the impression . . . there was something you wanted to tell us . . ."

"A great secret."

"So the legend says." I repeated.

"It can wait." I stared at him, shocked.

"Oh, does it have to?" I asked, put out.

"We shall meet again, Doctor, for the third time . . . for the last time . . . and the truth shall be told. Until that day . . ." He teleports himself away.

"That is enigmatic. That — that is — that is textbook enigmatic." I said, very impressed. I nod to myself, and then stand to face Cassandra. Rose moved to stand behind me. "And now for you." Cassandra looks up at me.

"But . . . everything's happy. Everything's fine . . . can't you just leave me?" She asked.

"You've lived long enough. Leave that body and end it, Cassandra." I told her.

"I don't want to die!" She started to cry.

"No one does." I said.

"Help me!" She cried.

"I can't." Suddenly her clone appears, making Cassandra gasp.

"Mistress!" He exclaimed.

"Ah! You're alive!" She said, shock.

"I kept myself safe. For you, mistress."

"A body . . . and not just that, a volunteer . . ." She stared at Chip, cogs ticking.

"Don't you dare. He's got a life of his own." I told her, warningly.

"But I worship the mistress!" Cassandra winks at Chip. "I welcome her."

"You can't Cassandra, you —" Cassandra ignores me and leaps into Chip's body. Jessamine falls forward with a gasp. I lunge out to catch her. "Oh! You all right?" Jessamine pauses and loses her balance again. "Whoa! Okay?"

"Yes." She finally gets her bearings and gathers herself together. She smiles up at me. "Hello."

"Hello. Welcome back." I return her smile. We gaze at each other, smiling, when we're distracted again by Cassandra.

"Oh, sweet Lord. I'm a walking doodle." She grumbled.

"You can't stay in there. I'm sorry, Cassandra, but that's not fair. I can take you to the City. They can build you a skin tank and you can stand trial for what you've done." I told her.

"Well, that would be rather dramatic. Possibly my finest hour. And certainly my finest hat." The three of us glanced at each other. "But I'm afraid we don't have time. Poor little Chip is only a half-life. And he's been through so much. His heart is racing so. He's failing. I don't think he's going to last —" Her legs give way. Jessamine and I lunge forward to support him.

"You all right?" I asked her.

"I'm fine." She pauses. Jessamine and I stare at her in concern. "I'm dying. But that's fine."

"I can take you to the City." I said, calmly.

"No, you won't. Everything's new on this planet. There's no place for Chip and me anymore. You're right, Doctor. It's time to die." Rose looks on rather upset. Cassandra swallows. "And that's good." Jessamine and I help her to her feet.

"Come on. There's one last thing I can do." I replied as we lead her to the TARDIS. Once we're inside, the girls help Cassandra to a chair while I put in the destination. When the TARDIS lands, the four of us step out. We could see the proper Cassandra laughing and talking, being the life and soul of the party. Cassandra turns to me.

"Thank you."

"Just go. And don't look back." I told her.

"Good luck." Rose said. She begins to walk away when Jessamine calls out to her, causing her to turn back to us. Jessamine walks over to her and pulls her into a hug, whispering something in her ear. Whatever she said caused Cassandra's face to glow. Jessamine walked back over to me and grabbed my hand, pulling me back inside the TARDIS.

"Jessamine, we —" She turned to me with a soft, solemn look.

"She doesn't need us to watch her die, Doctor. It's time to move on." She said as walks to Rose. I pause and look at the door for one last moment then started the TARDIS up for our next trip.
