The Doctor was lying in a hospital bed in his pyjamas, Violet sitting next to him. They were chatting as an actual Doctor and a group of medical students came up to them.

"Now then, Mr Smith, a very good morning to you. Who is this lovely young lady?" Mr Stoker, as his name tag read, asked.

The Doctor was going to answer, but Violet beat him to it. "I'm the fiancee. Violet Stewart." She smiled and held out her hand. The man shook it and turned to the Doctor.

"How are you today?"

"Aw, not so bad, still a bit, you know. Blah." He said lightly, looking at Violet, who smiled.

"John Smith, admitted yesterday with severe abdominal pains." He told the students before asking a dark-skinned woman, "Jones, why don't you see what you can find? Amaze me."

"That wasn't very clever, running around outside, was it?" She asked the Doctor.

"Sorry?" He looked confused.

"On Chancery Street this morning. You came up to me and took your tie off." Miss Jones told him.

"Really? What did I do that for?" He questioned.

"I don't know, you just did."

"Not me. I was here, in bed. Ask her." The Doctor pointed at his fake fiancee.

Jones frowned. "Well, that's weird, cause it looked like you. Have you got a brother?"

"No, not any more. Just me." He said regretfully, and Violet reached out to hold his hand.

"As time passes, I grow ever more infirm and weary, Miss Jones." Mr Stoker said, irritated.

"Sorry. Right." She grabbed her stethoscope and put it to the Doctor's chest. She moved it after a second to the other heart. She looked up at him, confused, and the Doctor winked. Violet swatted his arm playfully.

Mr Stoker sighed, "I weep for further generations. Are you having trouble locating the heart, Miss Jones?"

"Um. I don't know. Stomach cramps?" She suggested.

"That is a symptom, not a diagnosis. And you rather failed basic techniques by not consulting first with the patient's chart." He picked up the chart at the end of the bed and received an electric shock, dropping it in the process.

"That happened to me this morning." Jones said.

"I had the same thing on the door handle." Another medical student added.

Someone else nodded, "And me, on the lift."

"That's only to be expected. There's a thunderstorm moving in and lightning is a form of static electricity, as was first proven by...?" He looked around at the clueless students. "Anyone?"

"Benjamin Franklin." Violet and the Doctor said simultaneously, grinning.

"Correct!" Mr Stoker approved.

"My mate Ben, that was a day and a half. I got rope burns off that kite, and then I got soaked..." He started.

"...and then I got electrocuted."

"I think perhaps a visit from psychiatric." Mr Stoker moved away from them.

"Charming man." Violet commented sarcastically before pulling the Doctor's suit out of her bag. "Now, get dressed. I'm going to look around a bit."

She walked down the hallways and found a window. She gazed out of it and got caught up in her thoughts.

In the last few days, The Doctor and Violet had grown closer. As Time Lords, they barely needed sleep, but when the Doctor did sleep, he was plagued by nightmares. He didn't know it, but since that one night, Violet had been staying in his room as he slept, ready to wake him if the nightmares got too bad. She often took a book with her and read, but she spent a lot of time thinking.

Throught the loss of Rose, the Doctor had grown just a little more obnoxious, but Violet knew it was self-preservation. When he allowed himself to feel, he broke down. But she was always there to pick up the pieces. She had to be, because there was no one else who would.

Violet was snapped out of her thoughts when she saw the rain going upwards. Judoon. She ran to find the Doctor.

"Oh, there you are!" Violet pushed through some double doors that lead to a balcony, seeing the Doctor and the medical student from earlier.

"Hi. Uhm.. Miss Jones, is it?" She asked the woman.

"Yeah. Martha Jones. You're soon-to-be Mrs Smith, are you?" Martha asked with a look of slight jealousy on her face.

"No, just a cover. I'm Violet. I'm guessing you already know him." She pointed at the Doctor, looking at the scene around them. She picked up a pebble and threw it outwards. When it his a certain point, a bubble wrapped around the hospital revealed itself.

"Force field. How many people in this hospital?" Violet asked Martha.

"Like, a thousand?" She guessed.

Violet winced. "The air won't last long. And it's Judoon. They'll take forever."

"What are Judoon?" Martha asked.

"Come on." Violet didn't answer, just dragged both the Doctor and Martha inside as she saw the Judoon ships landing.

They were above the reception area, watching the Judoon filter in.

"Bo sco fo do no kro blo co sho ro!" The first chanted.

"We are citizens of planet earth. We welcome you in peace." A medical student said bravely. The Judoon pushed him against a wall and shone a blue light in his face.

"Please don't hurt me, I was just trying to help, I'm sorry, don't hurt me, please don't hurt me." He pleaded, afraid.

"Language assimilated. Designation Earth English. You will be catalogued." The Judoon drew a cross on his hand. "Category: human. Catalogue all suspects."

The Judoon started scanning all people on the bottom floor.

"Oh, look down there, you've got a little shop. I like a little shop." The Doctor commented.

"Never mind that! What are Judoon?" Martha asked.

"Galactic police." He replied.

"More like interplanetary thugs. Police for hire." Violet corrected him.

"And they brought us to the moon?"

"Neutral territory. According to galactic law, they've got no jurisdiction over the Earth, and they isolated us. That rain? Lightning? That was them, using an H2O scoop." He told her.

"What's that about 'galactic law'? Where'd you get that from? If they're police, are we under arrest? Are we trespassing on the moon or something?" Martha panicked.

"No. But I like that. Good thinking. No, it's more simple. They're making a catalogue, it means they're after something non-human."

"We're screwed, basically." Violet finished.

"Why?" Martha asked. Both Time Lords gave her a look. "Oh, you're kidding me." The Doctor raised an eyebrow. "Don't be ridiculous. Stop looking at me like that."

"Come on, then."

The Doctor and Violet were examining a computer with his sonic, when Martha came in.

"They've reached third floor." She announced and pointed. "What's that thing?"

"Sonic screwdriver." He told her off-handely.

"Well, if you're not going to answer me properly!" She complained.

"No, really, it is. It's a screwdriver, and it's sonic. Look." He held it out to her.

"What else have you got? A laser spanner?" She asked sarcastically.

"I did, but it was stolen by Emily Pankhurst, cheeky woman." He told her seriously.

"Really?" Violet asked. "Always wanted to meet her. She showed the boys where it was at, didn't she?"

The Doctor grinned at her before hitting the computer. "Oh, this computer! The Judoon must have locked it down. Judoon platoon upon the moon. Cause we were just travelling past, I swear, we were just wandering, not looking for trouble, honestly, but Violet noticed these plasma coils around the hospital, and that lightning, that's plasma coils, been building up for two days now, so I checked in, we thought something was going on inside, it turns out the plasma coils were the Judoon up above." He rattled on.

"But what were they looking for?" Martha interrupted him.

"Something that looks human, but isn't."

"Like you. Apparently." She smiled.

"Like us." He looked at her. "But not us."

"Haven't they got a photo?"

He grimaced, "Might be a shape-changer."

"Whatever it is, can't you just leave the Judoon to find it?" She asked.

Violet stepped in, "If they declare the hospital guilty of harbouring a fugitive, they'll sentence it to execution."

"All of us?"

"Oh yes. If I can find this thing first... Oh!" He shouted, making Martha take a step back. "Just that they're thick! Judoon are thick!" He hit the computer again. "They are completely thick! They wiped the records. Oh, that's clever."

"It never did help to hit a machine, you know. Budge over." Violet moved to the computer and pulled out her own sonic.

"What are we looking for?" Martha questioned.

"I don't know. Any patient admitted in the past week with unusual symptoms." The Doctor said, frustrated.

"I'll go ask Mr Stoker, he might know." She left, just as Violet restored the back-up.

"Oh, I'm brilliant, you have to admit." She laughed. "Come on, let's go find Martha."

They made it into the hallway before they bumped into her.

"I found her." She told them, breathing heavily from running.

"You did what?" He saw the Slabs and grabbed Martha's hand. "Run!" He shouted. The made their way down the stairs, Slabs hot on their tails. Unfortunately, the meet the Judoon coming up, so they go down the hallyway instead.

They skidded around corners before making it into a radiology room. The Doctor slammed to door shut in a Slab's face and used his sonic to seal it.

"When I say 'now', press the button." He dragged Martha to the controls.

"I don't know which one!" She shouted.

"Find out!" He replied in the same tone, plugging his sonic screwdriver into some of the machinery. Violet grabbed the manual and read it in a matter of seconds, just as the Slab broke down the door.

The Doctor yelled, "Now!" and Violet slammed down a big, yellow button. The Slab was zapped by the radiation, and fell to the floor, dead.

"What did you do?" Martha let out a breath.

"Increased the radiation by five thousand per cent. Killed him dead." He stated.

"Isn't that likely to kill you?" She panicked a little as Violet went out.

"It's only radiation. We used to play with roentgen bricks in the nursery." Violet told her lightly. "It's safe for you to come out, he's absorbed it all. Now he's going to make a fuss about expelling it." She grinned and watched him, highly amused.

"If I concentrate I can shake the radiation out of my body and into one spot. It's in my left shoe. Here we go, here we go, easy does it..." He shook his foot. "Out, out, out, out, out. Out, out, ah, ah, ah, ah. It is, it is, it is, it is, it is hot. Ah, hold on." He threw his shoe into a nearby bin. "Done."

"You're completely mad." Martha looked at him in utter disbelief.

"You're right. I look daft with one shoe." He took off the other and threw it way too. "Barefoot on the moon!"

She shook her head and went to the Slab, "So what is that thing? And where's it from? The planet Zovirax?"

"It's just a Slab. They're called 'Slabs'. Basic slave drones, see? Solid leather, all the way through." He explained.

"Someone has got one hell of a fetish." Violet commented, still very entertained.

"It came with that woman, Mrs. Finnegan. It was working for her. Just like a servant." She realised as the Doctor took the remains of his completely fried sonic screwdriver out of the X-Ray machine.

"My sonic screwdriver." He looked at it, actually sad.

"She was one of the patients, but-"

"My sonic screwdriver!" He exclaimed.

"She had a straw like some kind of vampire."

"I loved my sonic screwdriver!"

Violet laughed. "I'll make you a new one later, okay?"

"Doctor!" Martha called, annoyed.

"Sorry." He tossed his sonice away and smiled. "You called me 'Doctor'."

"Anyway!" She said, exasperated. "Miss Finnegan is the alien. She was drinking Mr. Stoker's blood."

"Funny time to take a snack. You'd think she'd be hiding. Unless - no. Yes, that's it, wait a minute. Yes!" The Doctor had a debate with himself, and Violet ignored him.

"She's an internal shape-changer. She wasn't drinking blood, she was assimilating it." She explained.

The Doctor added, "If she can assimilate Mr Stoker's blood, mimic the morphology, she can register as human. We've got to find her and show the Judoon. Come on!" He and Violet ran out of the room, leaving Martha to follow.

"That's the thing about Slabs. They always travel in pairs." The Doctor said quietly as they hid behind a water-cooler, watching the other Slab step out of a room.

"What about you?" Martha asked quietly.

"What about me what?"

"Are you two partners or something?" She motioned at him and Violet.

"Uh. Humans." He scoffed. "We're stuck on the moon running out of air with Judoon and a bloodsucking criminal, you're asking personal questions. Come on." The Doctor stood up, Violet following swiftly.

"I like that. 'Humans.' I'm still not convinced you're aliens." Martha told them as she stood up as well.

They stepped right in front of three Judoons, both of which scanned The Doctor and Violet.

"Non-human." They both confirmed.

Martha gasped. "Oh my God, you really are!"

"And again!" They set off running, going upstairs, where people were sitting on the floor, gasping for air.

"They've done this floor. Come on. The Judoon are logical and just a little bit thick. They won't go back to check a floor they've checked already. If we're lucky." The two Time Lords went ahead, but turned around when they heard Martha talk to another medical student.

"How are you feeling? Are you all right?" The Doctor asked her, looking concerned.

"I'm running on adrenaline." She smiled.

"Welcome to our world." He turned to Violet who just nodded.

"What about the Judoon?" Martha asked.

"Ah, great big lung reserves, it won't slow them down." He looked around. "Where's Mr Stoker's office?"

"It's this way."

They entered Mr Stoker's office, but only found the man's body. "She's gone! She was here."

Violet examined the body. "Drained him dry. Every last drop. She's a plasmavore."

"What was she doing on Earth?" She asked, horrified.

"Hiding. On the run. Like Ronald Biggs in Rio de Janeiro. What's she doing now? She's still not safe. The Judoon could execute us all. Come on."

"Just a sec." Violet closed Mr Stoker's eyes before following.

The Doctor was ranting, "Think, think, think. If I was a plasmavore surrounded by police, what would I do?"

Violet pointed and an MRI sign.

"Aah. She's as clever as me. Almost." He praised, and Violet slapped him.

"Cocky." She stated.

"Find the non-human. Execute." They heard the Judoon's voices, followed by various screams.

The Doctor grabbed Martha's shoulders."Stay here. We need time. You're going to have to hold them up."

"How do I do that?" She asked, confused.

"Martha, forgive me for this. It's to save a thousand lives, it means nothing. Honestly, nothing." He apologised in advance, then kissed her before running off with Violet.

"That was nothing?" Violet heard faintly, and laughed.

"You're in trouble now." She told the Doctor.

They went to MRI, and Violet opened the door, barging in.

"Oh my god! Have you seen those huge space rhinos? And I mean huge. And we're on the moon! Am I deluded? I was only here because of my husband," She pointed at the Doctor. "but maybe I should get myself checked over. Maybe it's oxygen starvation." She rambled at Ms Finnigan.

"Hold them!" The plasmavore ordered, and the Slab took hold of her and the Doctor, who had followed her in.

"That thing, that big machine thing, is it supposed to be making that noise?" The Doctor gestured at the MRI.

"You wouldn't understand." She dismissed.

"Isn't that a magnetic resonance imaging thing? Like a ginormous sort of a magnet? I did magnets at GCSE. Well, I failed, but all the same." He rambled on.

"The magnetic setting is now set to 50,000 Tesla." Mrs Finnigan told them, smug.

"Ooh. That's a bit strong, isn't it?"

"I can send out a magnetic pulse that will fry the brain-stems of every living thing within 250,000 miles. Except me, safe in this room." She smiled.

"But... hold on, hold on, I did geography for GCSE- I actually passed, unlike my husband- doesn't that distance include Earth?" Violet asked.

"Only the side facing the moon. The other half will survive. Call it my little gift."

"I'm sorry, you'll have to forgive me, I'm a little out of my depth. I've spent the past fifteen years working as a postman- hence the bunions- why would you do that?" The Doctor asked in fake confusion.

"With everyone dead, the Judoon ships will be mine, to make my escape." She said lightly.

"Now, that's weird. You're talking like you're some sort of an alien." Violet gasped.

"Right-o."

"No!"

"Oh, yes."

"You're joshing me!" The Doctor exclaimed.

"I am not." She smiled, obviously taking satisfaction in his surprise.

"I'm talking to an alien? In hospital? What, has the place got an ET department?" He joked.

"It's the perfect hiding place. Blood banks downstairs for a midnight feast, and all this equipment I'm ready to arm myself with should the police come looking." She shared with them.

"So, those rhinos, they're looking for you?" Violet questioned.

"Yes." She held up her hand. "But I'm hidden."

"Oh. Right! Maybe that's why they're increasing their scans." The Doctor lied, and Violet understood what he was trying to do.

"They're doing what?" Florence shrieked.

"Big chief rhino boy, he said, no sign of a non-human, we must increase our scans... up to setting two?" He pretended to recall.

"Then I must assimilate again." She said.

"What does that mean?" Violet scrunched up her face.

"I must appear to be human."

Violet smiled innocently. "Well, you're welcome to come home with us. Meet the little boy. Only a year old, my ma's taking care of him, bless. She'd be honoured. We can have cake. She makes brilliant cake."

"Why should I have cake? I've got my little straw." The plasmavore pulled a bendy straw out of her purse and walked up the the Doctor.

"That's nice. Milkshake? I like banana." The Doctor told her.

"You're quite the funny man. And yet, I think, laughing on purpose at the darkness. I think it's time you found some peace. Steady him!" She ordered. The Slab let go of Violet to hold the Doctor.

"What are you doing?" He looked down at the straw.

"I'm afraid this is going to hurt. But if it's any consolation, the dead don't tend to remember." She smiled.

Violet gasped. "You're going to kill him? You can't! I'm only 21, I don't want to be a widow!" She watched as Florence drank the Doctor's blood, his skin paling considerably. The Judoon entered suddenly, and Violet winced as she dropped him to the ground rather unelegantly. She ran to his side.

"You better wake up." She murmured. She listened to his hearts, but there was nothing. "No, no, no. You have to."

The Judoon dealt with the plasmavore as Violet started performing CPR on both of the Doctor's hearts. She heard the Judoon retreat and Martha panik as she looked at the MRI.

"Martha, pull out the plug." Violet told her. Martha did so, and Violet gave the Doctor her last breath as the air got thin. She collapsed just as he woke up and started to cough. He sat up, looking at Violet in concern, not even noticing Martha, who was leaning against a wall. The Doctor picked Violet up gently and carried her out, the medical student staggering out after her.

They walked to a window.

"Come on, come on, come on. Come on, Judoon, reverse it." The Doctor muttered. As it started to rain, he smiled down at the girl in his arms. "It's raining on the moon, Violet."

Martha was left alone outside of the pub, looking distressed, as she spotted the Doctor and Violet. She smiled and walked towards them as they turned around a corner.

She found them leaning against the TARDIS. "I went to the moon today." She said, smiling.

"A bit more peaceful than down here." Violet commented. "Uhm, I'll be back in a minute." She added as something caught her attention.

She walked onto the middle of the street. For a moment, she just stood there, observing, before she jumped out of the way as a car came. But she had heard something. She had heard drums.

Violet shook her head and went back to the TARDIS, seeing that Martha and the Doctor were already inside.

"So, where are you taking me?" Martha asked excitedly.

"Well, first of all, you look like you're about to pass out. So, we're gonna find you a room." Violet smiled.

After Violet had given Martha something to sleep in, she looked for the Doctor and found him in the control room. She leant against the doorway and watched him. He looked unusual with out his suit jacket and tie. After a while, he noticed her presence.

"You should get some sleep." She told him.

"I'm fine." He denied. "Just need a bit of coffee, that's all."

She sighed. "You had your blood sucked out of you. You need a little more than coffee, Theta."

"I know, I know. I'm no use to the universe if I'm sleep-deprived." He joked bitterly.

"You don't need to carry the weight of the universe alone, you know." Violet called after him as he stood up and walked to his room.

It was a few hours later when the TARDIS told her that the Doctor was having nightmares again. She, as always, rushed to his room.

"Theta!" She shook him gently. He was shaking, beads of sweat on his face. He woke up and whimpered when he saw Violet.

"Damnit, I'm sorry." He apologised. Violet shook her head and stroked some hair out of his face.

"It's okay. You're okay." She whispered. "Go back to sleep."

"You don't have to stay." He told her.

She smiled softly. "But I will. Sleep, Theta."

He closed his eyes and Violet sat down in the chair she had spent a lot of nights in. She tucked her legs under her body and started humming a Gallifreyan lullaby, watching the Doctor's chest rise and fall. Once his breathing slowed, she picked up one of the books lying around and started reading at a human pace, still humming softly.
