The Doctor was inside the TARDIS while Jennifer was saying her goodbyes. "Well, this is goodbye, for now," Jennifer said. "Be careful," Jackie said. "I will. I promise." Jennifer said. She hugged Jackie. "Have loads of fun JJ," Rose said as she hugged Jennifer. "Why don't you come?" Jennifer asked. "No, no. Maybe next time. You need some along time with The Doctor," Rose said. Jennifer smiled and walked up to Mickey and kissed him goodbye. "Love you," Mickey said. "Bye," Jennifer said.

Jennifer walked into the TARDIS. As soon as she closed the door, she looked at The Doctor. He gave her a big smile and Jennifer gave one back. "So where are we going?" Jennifer asked. "Further than we've ever gone before," The Doctor said.

The TARDIS materialized and Jennifer stepped out followed by The Doctor. "It's the year five billion and twenty three. We're in the galaxy M87, and this? This is New Earth," The Doctor said. They were on the other side of a river, just across a massive city. Cars zoomed past their heads. "This is just . . ." Jennifer said.

"Not bad. Not bad at all," The Doctor said with a grin. "This is amazing. I'll never get used to this. Different ground beneath my feet," Jennifer said. She hopped up and down. "What's that smell?" Jennifer asked. "Apple grass," The Doctor said with a smile. Jennifer smiled. "It's beautiful. I love this. Travelling with you, I love it," Jennifer said. "Me too. Come on," The Doctor said with a smile. He grabbed Jennifer's hand and they ran off.

The Doctor and Jennifer were laying down on The Doctor's coat. "So, the year five billion, the sun expands, the Earth gets roasted," The Doctor said. "That was our first date," Jennifer said with a smile. "We had chips," The Doctor said with a grin, "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 then find this place. Same size as the Earth, same air, same orbit. Lovely. Call goes out, the humans move in."

"What's the city called?" Jennifer asked. "New New York," The Doctor said. "Oh, come on," Jennifer said. "It is. It's the city of New New York. 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. What?" The Doctor asked. Jennifer smiled at The Doctor. "You're so different," Jennifer said. "New New Doctor," The Doctor said with a smile.

"Can we go and visit New New York?" Jennifer asked. The pair got up and The Doctor put his coat back on. "Well, I thought we might go there first," The Doctor said. The Doctor motioned towards a skyscraper. "What is it?" Jennifer asked. "Some sort of hospital. Green moon on the side. That's the universal symbol for hospitals. I got this. A message on the psychic paper," The Doctor said. On the psychic paper it said 'Ward 26 Please Come'.

"Someone wants to see me," The Doctor said. "And I thought we were just sight-seeing. Well, let's go then," Jennifer said. She and The Doctor linked arms and they walked to the hospital.

"Bit rich coming from you," Jennifer said. "I can't help it. I don't like hospitals. They give me the creeps," The Doctor said. '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.' The intercom said.

"Very smart. Not exactly NHS," Jennifer said. "No shop. I like the little shop," The Doctor said. "I thought this far in the future, they'd have cured everything," Jennifer said. "The human race moves on, but so do the viruses. It's an ongoing war," The Doctor said.

Jennifer looked at the nurses. They had cat faces. "They're cats," Jennifer said. "Now, don't stare. Think what you look like to them, all pink and yellow. That's where I'd put the shop. Right there," The Doctor said. The Doctor walked into the lift while Jennifer wasn't paying attention. She noticed that he was gone and went to where the lift was. "Hold on! Hold on!" Jennifer said. The lift closed.

"Oh, too late. I'm going up," The Doctor said. "It's all right, there's another lift," Jennifer said. "Ward 26 and watch out for the disinfectant," The Doctor said. "Watch out for what?" Jennifer asked. "The disinfectant," The Doctor said. Jennifer's lift opened and she walked in. "Ward 26," Jennifer said. The lift began moving. 'Commence stage one disinfection,' The computer said. Jennifer was drenched with water and she shrieked. It soon stopped. Next was the blow dry but Jennifer didn't mind it.

Jennifer stepped out of the lift. "The human child is clean," A man said. "Um, I'm looking for Ward 26," Jennifer said. "This way, Jennifer Tyler," The man said and he walked away. Jennifer picked up a metal bar and followed carefully.

Jennifer walked into a projector room. She watched what was playing on the wall. She recognized someone. She recognized the blonde woman. "Wait a minute," Jennifer said. Jennifer turned around. "Peekaboo!" Cassandra said. "Don't come anywhere near me, Cassandra," Jennifer said. "Why? What do you think I'm going to do? Flap you to death?" Cassandra asked. "Yeah, but what about Gollum?" Jennifer asked. "Oh that's just Chip. He's my pet," Cassandra said. "I worship the mistress," Chip said.

"Moisturise me, moisturise me," Cassandra said. Chip sprayed Cassandra. "He's not even a proper life form. He's a force grown clone. I modelled him on my favourite pattern. But he's so faithful. Chip sees to my physical needs," Cassandra said. "I hope that means food. How comes you're still alive?" Jennifer asked. "After you murdered me -" Cassandra said. "That was your own fault," Jennifer said.

"The brain of my mistress survived. And her pretty blue eyes were salvaged from the bin," Chip said. "What about the skin? I saw it. You got ripped apart," Jennifer said. "That piece of skin was taken from the front of my body. This piece is the back," Cassandra said.

"So you're talking out of your-" Jennifer said. "Ask not," Cassandra said. "The mistress was lucky to survive. Chip secreted m'lady into the hospital," Chip said. "So they don't know you're here?" Jennifer asked. "Chip steals medicine. Helps m'lady. Soothes her, strokes her," Chip said. "You can stop right there, Chip," Jennifer said. "But I'm so alone, hidden down here. The last Human in existence," Cassandra said. "Don't start that again. They've called this planet New Earth," Jennifer said. "A vegetable patch," Cassandra said. "And there's millions of Humans out there. Millions of them," Jennifer said.

"Mutant stock," Cassandra said. "They evolved, Cassandra. They just evolved, like they should. You stayed still. You got yourself all pickled and preserved, and what good did it do you?" Jennifer asked. "Oh, I remember that night. Drinks for the Ambassador of Thrace. That was the last time anyone told me I was beautiful. After that it all became such hard work," Cassandra said. "Well, you've got a knack for survival," Jennifer said. "But I've not been idle, Jennifer, tucked away underneath this hospital. I've been listening. The Sisters are hiding something," Cassandra said.

"What do you mean?" Jennifer asked. "Oh these cats have secrets. Hush, let me whisper. Come close," Cassandra said. "Yeah right. I'm not coming anywhere near you," Jennifer said. Jennifer made her way out and beams of energy caught her hands. "Chip, activate the psychograft," Cassandra said. "I can't move. Cassandra, let me go! What're you doing?" Jennifer asked. Light streams down from above Jennifer, containig her. "The lady's moving on. It's goodbye trampoline, and hello blondie," Cassandra said.

There was a whoosh of energy that went from Cassandra to Jennifer. Jennifer collapsed. "Mistress?" Chip asked. "Moisturise me. How bizarre. Arms, fingers, hair! Let me see! Let me see! Oh my God. I'm beautiful," Cass-Jennifer said with a smirk.

Cass-Jennifer looked at herself up and down. "Oh, baby, it's like living inside a bouncy castle!" Cass-Jennifer said with a grin. "The mistress is beautiful," Chip said. "Absolutement! Oh, but look," Cass-Jennifer said. The equipment that had been keeping flat Cassandra alive is fried. "Oh, the brain lead expired. My old mistress is gone," Chip said. "But safe and sound in here," Cass-Jennifer said.

"But what of the Jennifer child's mind?" Chip asked. "Oh, tucked away. I can just about access the surface memory. She's- Gosh, she's with The Doctor. A man. He's The Doctor. The same Doctor with a new face. That hypocrite! I must get the name of his surgeon. I could do with a little work. Although nice rear bumper. Hmm," Cass-Jennifer said.

Jennifer's phone rang. Cass-Jennifer took it out. "Oh, it seems to be ringing. Is it meant to ring?" Cass-Jennifer asked. "A primitive communications device," Chip said. Cass-Jennifer answered it. "JJ, where are you?" The Doctor asked. "How does she speak?" Cass-Jennifer asked. "Be Jennifer," Chip said. "Yeah," Cass-Jennifer said. "Where've you been? How long does it take to get to Ward 26?" The Doctor asked. "I'm on my way, governor," Cass-Jennifer said. "You'll never guess. I'm with the Face of Boe. Remember him?" The Doctor asked. "Of course I do. That big old boat race," Cass-Jennifer said.

"I'd better go. See you in a minute," The Doctor said. He hung up. "This Doctor man is dangerous," Chip said. "Dangerous and clever. I might need a mind like his. The Sisterhood is up to something. Remember that Old Earth saying, never trust a Nun? Never trust a Nurse. And never trust a cat. Perfume?" Cass-Jennifer said. Cass-Jennifer grabbed the perfume. She tucks it down her décolletage. Chip and Cass-Jennifer made their way to Ward 26.

Cass-Jennifer reached Ward 26. She watched as The Doctor looked around the room, wearing his glasses. "There you are. Come and look at this patient. Marconi'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. Pallidome Pancrosis. Kills you in ten minutes, and he's fine. I need to find a terminal. I've got to see how they do this. Because if they've got the best medicine in the world, then why is it such a secret?" The Doctor asked.

The two walked into a hallway. "I can't Adam and Eve it," Cass-Jennifer said. "What's with the voice?" The Doctor asked. "I don't know. Just larking about. New Earth, new me," Cass-Jennifer said. "Well, I can talk. New New Doctor," The Doctor said. "Aren't you just," Cass-Jennifer said. Cass-Jennifer grabbed The Doctor and gave him a long and hard kiss. When she pulled away, The Doctor stared at her. "Terminal's this way," Cass-Jennifer said. She moved forward. "Yep, still got it," The Doctor said and followed her.

The Doctor and Cass-Jennifer were looking at a computer screen. "Nope, nothing odd. Surgery, post-op, nano-dentistry. No sign of a shop. They should have a shop," The Doctor said. "No, it's missing something else. When I was downstairs, those Nurse Cat Nuns were talking about Intensive Care. Where is it?" Cass-Jennifer asked. "You're right. Well done," The Doctor said.

"Why would they hide a whole department? It's got to be there somewhere. Search the sub-frame," Cass-Jennifer said. "What if the sub-frame's locked?" The Doctor asked. "Try the installation protocol," Cass-Jennifer said. "Yeah. Of course. Sorry. Hold on," The Doctor said. The Doctor got out his Sonic Screwdriver and used it on the screen. When he finished, the wall slid down to reveal a corridor. Cass-Jennifer walked forward and The Doctor followed.

"Intensive Care. Certainly looks intensive," The Doctor said. Cass-Jennifer led to way to an area where it looked like there were tombs. The Doctor opened one with Sonic Screwdriver. There was a very sick looking man. "That's disgusting. What's wrong with him?" Cass-Jennifer asked. "I'm sorry. I'm so sorry," The Doctor said. He closed the door and opened another one. It contained a young woman. "What disease is that?" Cass-Jennifer asked. "All of them. Every single disease in the galaxy. They've been infected with everything," The Doctor said. "What about us? Are we safe?" Cass-Jennifer asked.

"The air's sterile. Just don't touch them," The Doctor said. He close the door. "How many patients are there?" Cass-Jennifer asked. "They're not patients," The Doctor said. "But they're sick," Cass-Jennifer said. "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," The Doctor said. "Why don't they just die?" Cass-Jennifer asked. "Plague carriers. The last to go," The Doctor said. "It's for the greater cause," One of the cat nurses said.

"Novice Hame, When you took your vows, did you agree to this?" The Doctor asked. "The Sisterhood has sworn to help," Hame said. "What, by killing?" The Doctor asked. "But they're not real people. They're specially grown. They have no proper existence," Hame said. "What's the turnover, hmm? Thousand a day? Thousand the next? Thousand the next? How many thousands? For how many years? How many!" The Doctor asked. "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," Hame said.

"These people are alive," The Doctor said. "But think of those Humans out there, healthy and happy, because of us," Hame said. "If they live because of this, then life is worthless," The Doctor said. "But who are you to decide that?" Hame asked. "I'm The Doctor. 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 me," The Doctor said. "Just to confirm. None of the humans in the city actually know about this?" Cass-Jennifer asked.

"We thought it best not," Hame said. "Hold on. I can understand the bodies. I can understand your vows. One thing I can't understand. What have you done to Jennifer?" The Doctor asked. "I don't know what you mean," Hame said. "And I'm being very, very calm. You want to be aware of that. Very, very calm. And the only reason I'm being so very, very calm is that the brain is a delicate thing. Whatever you've done to Jennifer's head, I want it reversed," The Doctor said. "We haven't done anything," Hame said. "I'm perfectly fine," Cass-Jennifer said.

"These people are dying and JJ would care," The Doctor said. "All right, clever clogs," Cass-Jennifer said. She grabbed The Doctor's tie. "Smarty pants. Lady-killer," Cass-Jennifer said. "What's happened to you?" The Doctor asked. "I knew something was going on in this hospital, but I needed this body and your mind to find it out," Cass-Jennifer said. "Who are you?" The Doctor asked.

Cass-Jennifer pulled him closer. She leaned in close to his ear. "The last human," Cass-Jennifer said. "Cassandra?" The Doctor asked. "Wake up and smell the perfume," Cass-Jennifer said. She sprayed the vial in front of The Doctor's nose and he passed out.

"You've hurt him. I don't understand. I'll have to fetch Matron," Hame said. "You do that, because I want to see her. Now, run along. Sound the alarm!" Cass-Jennifer said. Hame ran off. Cass-Jennifer walked over to a set of cables and pulled them. The alarm went off.

The Doctor was inside a cell. "Let me out! Let me out!" The Doctor said. "Aren't you lucky there was a spare? Standing room only," Cass-Jennifer said. "You've stolen Jennifer's body," The Doctor said. "Over the years, I've thought of a thousand ways to kill you, Doctor. And now, that's exactly what I've got. One thousand diseases. They pump the patients with a top-up every ten minutes. You've got about three minutes left. Enjoy," Cass-Jennifer said. "Just let Jennifer go, Cassandra," The Doctor said. "I will. Maybe. Now hushaby. It's showtime," Cass-Jennifer said.

"Anything we can do to help?" The nurse, Jatt asked. "Straight to the point. I want money," Cass-Jennifer said. "The Sisterhood is a charity. We don't give money. We only accept," The other nurse, Casp said. "The humans across the water pay you a fortune, and that's exactly what I need. A one-off payment, that's all I want. Oh, and perhaps a yacht. In return for which, I shall tell the city nothing of your institutional murder. Is that a deal?" Cass-Jennifer asked. "I'm afraid not," Casp said. "I'd really advise you to think about this," Cass-Jennifer said.

"Oh, there's no need. I have to decline," Casp said. "I'll tell them, and you've no way of stopping me. You're not exactly Nuns with Guns. You're not even armed," Cass-Jennifer said. "Who needs arms when we have claws?" Casp asked. She unleashed her claws. "Well, nice try. Chip? Plan B," Cass-Jennifer said. Chip pulled a lever opening every door. All the sick people stepped out followed by The Doctor. "What've you done?" The Doctor said. "Gave the system a shot of adrenaline, just to wake them up. See you!" Cass-Jennifer said. She and Chip started walking away. The Doctor ran after them. All the doors began sparking causing them to move faster. All the doors opened.

"Oh, my God," Cass-Jennifer said. "What the hell have you done?" The Doctor said. "It wasn't me," Cass-Jennifer said. "One touch and you get every disease in the world, and I want that body safe, Cassandra. We've got to go down," The Doctor said. "But there's thousands of them!" Cass-Jennifer said. "Run! Down! Down! Go down!" The Doctor said. They began running down the stairs. They reached the basement and Cass-Jennifer went to the lift. "No, the lifts have closed down. That's the quarantine. Nothing's moving," The Doctor said. "This way!" Cass-Jennifer said.

Cass-Jennifer ran in the opposite direction, The Doctor and Chip followed. Chip was cut off from Cass-Jennifer and The Doctor as more infected people came. "Someone will touch him," The Doctor said. "Leave him! He's just a clone thing. He's only got a half life. Come on!" Cass-Jennifer said. "Mistress!" Chip called. "I'm sorry, I can't let her escape," The Doctor said. Cass-Jennifer continued running and The Doctor followed. Cass-Jennifer ran to a door but there were more infected people.

"We're trapped! What am I going to do?" Cass-Jennifer asked. "Well, for starters, you're going to leave that body. That psychograft is banned on every civilised planet. You're compressing Jennifer to death," The Doctor said. "But I've got nowhere to go. My original skin's dead," Cass-Jennifer said. "Not my problem. You can float as atoms in the air. Now, get out. Give her back to me," The Doctor said. He pointed the Sonic Screwdriver at Cass-Jennifer. "You asked for it," Cass-Jennifer said.

Cassandra left Jennifer's body and went into The Doctor's body. "My head. Where'd she go?" Jennifer asked. "Oh, my. This is different," Cass-Doctor said. "Cassandra?" Jennifer asked. "Goodness me, I'm a man. Yum. So many parts. And hardly used. Oh, oh, two hearts! Oh, baby, I'm beating out a samba!" Cass-Doctor said. "Get out of him!" Jennifer demanded. "Oo, he's slim, and a little bit foxy. You've thought so too. I've been inside your head. You've been looking. You like it," Cass-Doctor said. The infected people burst through the door.

"What do we do? What would he do? The Doctor, what the hell would he do?" Cass-Doctor asked. "Ladder. We've got to get up," Jennifer said. "Out of the way!" Cass-Doctor said. Cass-Doctor pushed Jennifer out of the way. After Cass-Doctor, Jennifer followed. "Get out of The Doctor's body, he can think of something," Jennifer said. "Yap, yap, yap. God, it was tedious inside your head. Hormone city," Cass-Doctor said. "We're going to die if-" Jennifer said. Casp grabbed her ankle. "All our good work. All that healing. The good name of the Sisterhood. You have destroyed everything," Casp said.

"Go and play with a ball of string" Cass-Doctor said. "Everywhere, disease. This is the human world. Sickness!" Casp said. She was touched by an infected person. She fell, screaming. "Move!" Jennifer yelled.

They reached the end of the ladder. Cass-Doctor tried opening the door. "Now what do we do?" Cass-Doctor asked. "Use the Sonic Screwdriver," Jennifer said. Cass-Doctor grabbed the Sonic Screwdriver. "You mean this thing?" Cass-Doctor asked. "Yes, I mean that thing!" Jennifer shouted. "Well, I don't know how. That Doctor's hidden away all his thoughts," Cass-Doctor said. "Go back into me. The Doctor can open it. Do it!" Jennifer said. "Hold on tight," Cass-Doctor said. Cassandra went back into Jennifer. "Oh, good. Open it!" Cass-Jennifer shouted.

"Not till you get out of her," The Doctor said. "We need the Doctor," Cass-Jennifer said. "I order you to leave her," The Doctor said. Cassandra swapped back. "No matter how difficult the situation, there is no need to shout," Cass-Doctor said. "Get out of him!" Jennifer said. "But I can't go into you, he simply refuses. He's so rude," Cass-Doctor said. "I don't care. Just do something," Jennifer said. "Oh, I am so going to regret this," Cass-Doctor said. Cassandra swapped to the lead woman on the ladder below them.

"Oh, sweet Lord. I look disgusting," Cassandra said. The Doctor opened the doors. "Nice to have you back," The Doctor said to Jennifer. Cassandra went back into Jennifer before she could jump. "That was your last warning, Cassandra!" The Doctor said. "Inside her head. They're so alone. They keep reaching out, just to hold us. All their lives and they've never been touched," Cass-Jennifer said sadly. The Doctor offered her hand and she took it. There was banging at the door. The Doctor and Cass-Jennifer walked forward and into Ward 26. A woman lunged at them with a metal stand.

"We're safe! We're safe! We're safe! We're clean! We're clean! Look, look," The Doctor said. "Show me your skin," The woman said. "Look, clean. Look, if we'd been touched, we'd be dead. So how's it going up here? What's the status?" The Doctor asked. "There's nothing but silence from the other wards. I think we're the only ones left. And I've been trying to override the quarantine. If I can trip a signal over to New New York, they can send a private executive squad," The woman, Clovis said. "You can't do that. If they forced entry, they'd break quarantine," The Doctor said. "I am not dying in here!" Clovis said. "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!" The Doctor said.

"Not if it gets me out," Clovis said. "All right, fine. So I have to stop you lot as well. Suits me. Jennifer, novice Hame, everyone! Excuse me, your Grace. Get me intravenous solutions for every single disease. Move it!" The Doctor said.

Everyone collected bags of liquid. The Doctor wrapped himself in rope. Cass-Jennifer walked over to him and helped attach the bags onto the rope. "How's that? Will that do?" The Doctor asked. "I don't know. What's it even for?" Cass-Jennifer asked.

The Doctor walked to the lift and opened the doors. "The lifts aren't working," Cass-Jennifer said. "Not moving. Different thing. Here we go," The Doctor said. He took steps away from the lift. He put the Sonic Screwdriver between his teeth. He ran and jumped. He held onto the rope. "What do you think you're doing?" Cass-Jennifer asked.

"I'm going down," The Doctor said. He attached a piece of equipment to the lift cable with his Sonic Screwdriver. "Come on," The Doctor said. "Are you crazy!? Not in a million years," Cass-Jennifer 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?" The Doctor said.

"Seal the door!" Clovis said. Cass-Jennifer was trapped with the infected people. She jumped onto The Doctor's back. "You're completely mad but I can see why she likes you," Cass-Jennifer said. "Going down!" The Doctor said. The Doctor and Cass-Jennifer began zooming down the cable. As soon as they got closer to the lift, The Doctor had them come to a gentle stop.

"Well, that's one way to lose weight," Cass-Jennifer said. "Now, listen. When I say so, take hold of that lever," The Doctor said. "There's still a quarantine down there, we can't-" Cass-Jennifer said. "Hold that lever! I'm cooking up a cocktail. I know a bit about medicine myself," The Doctor said.

Cass-Jennifer held down the lever. The Doctor began pouring the liquids into a tank. "Now, that lever's going to resist. But keep it in position. Hold onto it with everything you've got," The Doctor said. "What about you?" Cass-Jennifer asked. "I've got an appointment. The Doctor is in," The Doctor said. He dropped down into the lift and he opened the lift door.

"I'm in here! Come on!" The Doctor said. "Don't tell them," Cass-Jennifer said. "Pull that lever!" The Doctor said. As the disinfected people got in the elevator, Cass-Jennifer pulled the lever. "All they want to do is pass it on. Pass it on!" The Doctor said. "Pass on what? Pass on what?" Cass-Jennifer asked. "Pass it on!" The Doctor said.

The Doctor helped Cass-Jennifer get into the lift. "What did they pass on? Did you kill them? All of them?" Cass-Jennifer asked. "No. That's your way of doing things," The Doctor said. He and Cass-Jennifer walked out of the lift. "I'm The Doctor, and I cured them," The Doctor said. A woman hugged The Doctor. "That's right. Hey, there we go, sweetheart. Go to him. Go on, that's it. That's it. It's a new sub-species, Cassandra. A brand new form of life. New humans! Look at them. Look! Grown by cats, kept in the dark, fed by tubes, but completely, completely alive. You can't deny them, because you helped create them. The human race just keeps on going, keeps on changing. Life will out! Ha!" The Doctor said.

A little later, The Doctor and Cass-Jennifer watched as a staff member was arrested. "The Face of Boe," The Doctor said. He ran off and Cass-Jennifer followed him. "You were supposed to be dying," The Doctor said. "There are better things to do today. Dying can wait," The Face Of Boe said, telepathically. "I hate telepathy. Just what I need, a head full of big face," Cass-Jennifer said. "Shh!" The Doctor said. "I have grown tired with the universe, Doctor, but you have taught me to look at it anew," The Face Of Boe said.

"There are legends, you know, saying that you're millions of years old," The Doctor said. "There are? That would be impossible," The Face Of Boe said. "Wouldn't it just. I got the impression there was something you wanted to tell me," The Doctor said. "A great secret," The Face Of Boe said. "So the legend says," The Doctor said. "It can wait," The Face Of Boe said. "Oh, does it have to?" The Doctor asked. "We shall meet again, Doctor, for the third time, for the last time, and the truth shall be told. Until that day," The Face Of Boe said. The Face Of Boe beamed away.

"That is enigmatic. That, that is, that is textbook enigmatic. And now for you," The Doctor said. "But everything's happy. Everything's fine. Can't you just leave me?" Cass-Jennifer asked. "You've lived long enough. Leave that body and end it, Cassandra," The Doctor said. "I don't want to die," Cass-Jennifer said. "No one does," The Doctor said. "Help me," Cass-Jennifer said with tears. "I can't. I'm in love with that body and I want her back," The Doctor said.

"Mistress!" Chip called. "You're alive," Cass-Jennifer said. "I kept myself safe for you, mistress," Chip said. "A body. And not just that, a volunteer," Cass-Jennifer said. "Don't you dare. He's got a life of his own," The Doctor said. "But I worship the mistress. I welcome her," Chip said. "You can't, Cassandra, you-" The Doctor said.

Cassandra left Jennifer and went into Chip. Jennifer fell and The Doctor caught her. "You all right?" The Doctor asked. "Yeah," Jennifer said. She looked up at The Doctor. "Hello," Jennifer said with a smile. "Hello. Welcome back," The Doctor said with a smile. The Doctor leaned in but then Cass-Chip interrupted. "Oh, sweet Lord. I'm a walking doodle," Cass-Chip said.

"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," The Doctor said. "Well, that would be rather dramatic. Possibly my finest hour, and certainly my finest hat, 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-" Cass-Chip said. Cass-Chip fell.

Jennifer and The Doctor hold Cass-Chip. "Are you all right?" Jennifer asked. "I'm fine. I'm dying, but that's fine," Cass-Chip said. "I can take you to the city," The Doctor said. "No, you won't. Everything's new on this planet. There's no place for Chip and me any more. You're right, Doctor. It's time to die, and that's good," Cass-Chip said. "Come on. There's one last thing I can do," The Doctor said.

The TARDIS materialized at the party that Jennifer saw in the projection room earlier. There was human Cassandra. "Thank you," Cass-Chip said. "Just go. And don't look back," The Doctor said. "Good luck," Jennifer said. Jennifer and The Doctor watched the scene before them. Cass-Chip collapsed and human Cassandra cradled him. The Doctor grabbed Jennifer's hand and they made their way to the TARDIS.
