A/N: I know I was supposed to post this four days ago but, in my defense, I spent three of those days sick and the fourth at the engagement party of my boyfriend's best friend.

As it is, here's the first chapter to the second part of this series - tell me what you think!

"The Footprint," the Doctor told Martha as he saw her running to him. "It's a gravity pulse. It stamps down, the rocket shoots up – bit primitive, it's gonna take the both of us to keep it stable."

"Doctor, it's the Professor," Martha said, looking scared. "He's got this watch, he's got a fob watch, it's the same as yours," she added, making the Doctor turn to look at her. "Same writing on it, same everything."

"Don't be ridiculous," the Doctor said. Yana couldn't possibly have a fob watch, he just couldn't. If he had, then…

"I asked him, he said he's had it his whole life," Martha went on.

"So?" Jack asked. "He's got the same watch."

"Yeah, but it's not a watch," Martha corrected. "It's this chameleon thing."

"No, no, no…" the Doctor muttered. "It's this… it's this thing, this device that rewrites biology… changes a Time Lord into a Human."

"And it's the same watch!" Martha insisted.

"It can't be," the Doctor repeated. Which Time Lord could have survived the Time War? Which of them could it be?

"That means he could be a Time Lord!" Jack called out. "You might not be the last one!"

"Jack, keep it level!"

"But that's brilliant, isn't it?" Martha questioned.

"Yes, it is, course it is!" the Doctor muttered. Another Time Lord… just the thought of it was… terrifying. "Depends which one," he added. "Fantastic, yeah." There could be more. He might not be the last of his kind and if one Time Lord survived… how many others could have? "But they died, the Time Lords, all of them, they died."

"Not if he was human!" Jack noted.

"What did he say?" the Doctor asked, before all but screaming at Martha when she didn't reply, "Martha, what did he say?!"

"He looked at the watch like he could hardly see it," Martha stuttered out. "Like… that perception filter thing."

"What about now?" the Doctor asked. "Can he see it now?"

"If he escaped the Time War, then it's a perfect place to hide," Jack said, running towards them from the other side of the corridor. "The end of the universe!"

"And think what the Face of Boe said!" Martha added. "His dying words! He said…"

Martha trailed off but the Doctor didn't need the reminder as he turned he last notch to make the rocket fly, before looking at the screen, where the letters of the Professor's name were displayed to him.

You Are Not Alone.

"Lieutenant, have you done it?" the Doctor called into the radio. "Did you get velocity? Have you done it? Lieutenant, have you done it?"

"Affirmative," the Lieutenant replied. "We'll see you in Utopia."

"Good luck," the Doctor said, turning around and starting to run back towards Yana's lab. "Eva's alone with him!" he called out to Jack and Martha. "Eva's alone with him, and she was scared…"

"Do you think she knows who he is?" Jack asked.

"I think she does," the Doctor confirmed. "And that knowledge was enough for her to have a panic attack." He headed towards the door, only to have it slammed down right in front of him. "Get it open!" he screamed at Jack, aiming his sonic screwdriver at the systems in the hopes something – anything – will happen. "Get it open!"

It took a moment but eventually, the Doctor found the right setting. He didn't even wait for the door to be completely open before running through it, a single thought in his mind.

Eva.

They ran, intent on taking the fastest route to the lab before noticing a group of Futurekind standing in front of them. Quickly, he turned around, stretching his mind in the attempt to think of another way to get to the lab.

"This way!" Jack called, taking a sharp turn and the Doctor followed him, finding himself in front of yet another locked door.

"Professor!" he called out, taking out his sonic screwdriver once more. "Professor, let me in! Let me in! Jack, get the door open now!" he ordered. "Professor, where are you? Chantho, are you there? I need to explain, whatever you do, don't open that watch. Eva? Eva, can you hear me? Eva!"

"They're coming!" Martha screamed.

"Open the door!" the Doctor called out. "Open the door, please! I'm begging you, professor, please listen to me! Just open the door, please!"

Jack slammed the handle of his gun on the lock, effectively breaking it and allowing them to walk into the room. For a moment, the Doctor could see the terrified look in Eva's eyes before Yana pulled her into the TARDIS.

He tried opening the door, first with his key and later with the screwdriver but Yana must have locked it from the inside, since nothing seemed to happen.

"Let me in," the Doctor called out, banging on the TARDIS doors. "Eva! Eva!" He could hear Martha and Jack talking behind him, but their words held no meaning in his mind. If something happened to Eva… it was all his fault. "I'm begging you," he all but screamed. "Everything's changed! It's only the two of us! We're the only ones left! Eva! Eva!"

He watched in horror as bright regeneration energy came out of the TARDIS's windows, only brought back to reality at the sound of Martha's scream.

"Doctor, you'd better think of something!" Jack called out.

"Now then, Doctor," a new voice said from inside the TARDIS. "Ooo, new voice. Hello. Hello. Hello," he said, trying out how the syllables sounded in his mouth. "Anyway, why don't we stop and have a nice little chat while I tell you all my plans and you can work out a way to stop me, I don't think!"

"Hold on," Martha said, looking up. "I know that voice."

"I'm asking you really properly," the Doctor begged. "Just stop. Just think!"

"Use my name," the voice said coldly, and the Doctor felt a tightening in his chest as he spoke again.

"Master," he almost whispered. "I'm sorry."

"Tough!" the Master called out, and even before the Doctor heard the TARDIS's signature whooshing, he knew what the other Time Lord was going to do.

He took out his screwdriver, trying to remember the correct setting when a piercing scream cut through the air.

"Doctor!"

It felt like a thousand knives were cutting through his hearts at the sound of Eva's voice but he ignored it as he aimed his screwdriver at the TARDIS, sabotaging the navigation systems.

"Doctor!" Eva called out again. "Doctor, please! Please!"

The Doctor could feel, more than see or hear, sparks coming out of the TARDIS console as what he did was complete. Eva kept screaming for him in the background, but he didn't know what he could do other than hope for her necklace to take her away.

"Oh, no you don't!" he heard the Master calling. "End of the universe. Have fun. Bye, bye!"

"Eva!" the Doctor called, realizing she was left alone with the Master now. "Eva!"

"Doctor!" Eva screamed back. "Doctor!"

The TARDIS disappeared from sight and the Doctor was left looking at where it was just moments earlier, his throat dry and Eva's voice ringing in his ears.

EMH

Eva was lulled back awake by a soft hand that played with her hair. It felt nice, she thought to herself, the long fingers twisting a curl gently and massaging her scalp. She sighed in content, pressing her head closer to the hand and as the other person chuckled lightly, an understanding came upon her.

This was not the Doctor's chuckle.

She jerked awake, jumping out of her bed and falling to the floor. Pain came from her elbow as it made contact with the floor and when she reached out to check the wound, she discovered she was wearing significantly less than she was when she passed out in the Console Room.

"Calm down," the Master said. "I'm not going to hurt you."

"Forgive me if I find that hard to believe," Eva snarled, pulling her blanket off the bed and using it to cover her body. "Where are my clothes?"

"I took them off when I put you in your bed," the Master replied. "Don't worry, I didn't touch your undergarments. I did try to take off your socks but you are, apparently, very ticklish. Who knew?" he added with a small smile.

"Get out of my room," Eva said.

"I'm not here to hurt you," the Master repeated.

"I don't believe you," Eva said once more. "And even if I did, I wouldn't care."

"Why don't you believe me?" the Master asked. "I never did anything to hurt you."

Eva pulled herself up, finally able to look at him without her neck protesting. He wasn't much taller than her – an inch or two, for sure, but certainly not as tall as some of the Doctor's regenerations were. Honestly, when she stood next to Three or Four, she felt like a midget.

It was a lot easier to be intimidating when you could look in the eyes of the person you were talking to.

"You stabbed a sword through my chest," she accused.

"I never meant you any harm," the Master insisted.

"You were screaming 'If I can't have you, neither could he!'"

The Master winced. "I'll admit," he said, "Not my brightest moment."

"What about when you tried to use me to get to the Doctor?" Eva questioned. "Or when you tried to release entropy into the universe, knowing I'll die?"

"That was a long time ago," the Master said. "Things are different now."

"It wasn't that long ago for me," Eva said. "It wasn't even a year ago for me."

"No longer than ten months, I know," the Master said.

"What?" Eva asked, stopping to count back the months since she first appeared in this universe. "How do you know that?"

"I ran some tests on you," the Master explained.

"What?" Eva asked. "When?"

"While you slept," the Master said dismissively.

"You ran tests on me while I slept? Do you even start to understand how creepy –"

"Do you intend to let me tell you the results any time soon or are you going to keep questioning the morals we both know I don't have?" the Master asked.

Heat made itself known on Eva's cheeks and she looked down, breaking eye contact with the Master for the first time since she woke up. "Sorry," she muttered.

"It's alright," he replied. "What I was trying to tell you is that the tests results indicated severe malnourishment for the past ten months or so, in addition to irregular hormone levels that suggests uneven sleep patterns, and several infections caused by your lack of ability to keep up regular hygiene habits."

"And in human language?" Eva questioned.

"You rarely eat, and it's affecting your health," the Master said. "You barely sleep, which affects your hormone levels and, in turn, your health. And small cuts that could have quickly healed if they were treated properly and kept clean became infections that would have killed you if it wasn't for the fact that you can't die.

"In short," he concluded, "If you could die, life with the Doctor would have killed you already. And that's without mentioning all of the other life-threatening situations he has the tendency to throw himself – and you – into."

"Is it really that bad?" Eva asked. Of course, she knew her life jumping around the Doctor's timeline weren't the healthiest thing that could have happened to her, but surely it wouldn't have killed her.

"It's worse," the Master said curtly. "Starting today, you'll take antibiotics against the infection. The TARDIS assisted me in setting up a diet that should get you to normal health in about two months and until your hormone levels return to normal, you will take a medicine that will make sure you sleep exactly eight hours a night."

"You did all of that," Eva said slowly, "To help me?"

"I already told you," the Master frowned, "I don't want to hurt you."

"There's a major difference between wanting to keep me alive and tending me back to health," Eva commented.

"Just because that idiot couldn't care less doesn't mean I'm the same," the Master replied. "Now get dressed and take your meds, we have a lot to do and not a lot of time."

"We?" Eva repeated.

"Yes," the Master said, daring her to argue with him. "We. The TARDIS landed in London, the day before Christmas of 2006. Harriet Jones is now Prime Minister," he added. "Apparently she made some changes in the economy, I have to say this woman knew what she was doing. Anyway, we need to start making arrangements for our stay here – a place to live, a job –"

"Forged documents," Eva added bitterly. "Neither of us exists here."

"That shouldn't be that much of a problem," the Master shrugged. "I got along with less."

"You were also brainwashing innocent people by the hundreds," Eva retorted.

"I was only doing it by the dozens," the Master protested. "But if it makes you feel better, I won't do it to any more people than I absolutely have to."

"Fine," Eva sighed, knowing it was going to be the best she got from the Time Lord. "What do you want me to do, anyway?"

"Put on something pretty," the Master said. "We're having a day out."

He turned around, starting to leave the room and Eva sighed to herself before realizing what was missing – what had been missing since she woke up.

"Master!" she called out and he turned around, a pleased expression on his face.

"Yes?" he asked.

"My necklace," Eva said. "Where is it?"

"Safekeeping," the Master smirked. "Couldn't have you jumping around now, could we?"

And with that, he walked out of the room, leaving Eva shivering even though the room wasn't cold.

EMH

She wore a simple blue dress the TARDIS provided her with, matched with blue shoes and a small blue bag. As she walked out, she noticed the door was a deep blue colour as well, with patches of amber here and there.

"Look what I found!" the Master called out when she walked through the doors that led to the Console Room. At one of the corners, she could see the Doctor's hand in a jar, but the Master ignored the place her eyes wandered to as he pushed something into her hand. "Apparently, the Doctor keeps a stash of psychic paper in his second drawer."

Eva frowned for a moment, before deciding to drop the subject of the Master going through the Doctor's personal belongings and turning to look at the paper he handed her.

It seemed like a normal ID card, one that she saw people using when she was younger. She was too young to have one when they came out, and it was cancelled before she was old enough for reasons she didn't care much for at the age of fourteen, but now that they were back in the years the cards were used, it only made sense both she and the Master would need to have those.

However, it was the name on the card that made her breath hitch in her throat.

Surname: Saxon
Given Names: Harold Ronald
Date of Birth: 10-07-1970
Place of Birth: Manchester

"Harold Saxon," she repeated aloud.

"Harry for short," the Master said. "And one for you," he added, handing her a second paper.

Surname: Saxon
Given Names: Eva Merida
Date of Birth: 04-03-1987
Place of Birth: London

"My daughter," the Master smiled. "It will probably take us a couple of weeks to properly forge and submit the documents in order to get real ones, but this will do well for now."

Eva felt sick, reaching out a hand to lean on the console. "How did you know my middle name?" she asked.

"The Doctor has a file on you in his database," the Master shrugged. "You must have told it to him once and he put it in the system. Now, I know your official birthday is on December 1st, but March 4th is when your body will next reach the end of a year cycle of living."

Eva closed her eyes, trying to comprehend what he just told her. He had preformed a series of tests on her body while she slept, that much she already knew, but knowing that not only did the Doctor had a file on her in the TARDIS database, but that the Master read through it? That was too much.

"What else is written in there?" she asked.

"Not much," the Master shrugged. "There's a DNA sample, but so far it's not a match to anything in his systems. Date of birth, full name, references to times when you were referred to as 'The Omniscient' – most of these are still in your future – and percentage of Human at different ages."

"What?" Eva asked, confused. "What do you mean percentage of Human?"

"You didn't know you weren't completely Human?" the Master asked, confused.

"I did," Eva replied, "But why does he needs the data from different ages?"

"He didn't tell you?" the Master questioned. "Really?"

"Tell me what?"

"Your cells," the Master said. "They're constantly mutating – your DNA is constantly changing. Your Human percentage is slowly descending."

Eva furrowed her brows in worry and confusion. "What percent Human am I now?" she asked.

"I don't know," the Master replied. "I'll have to check, but I'm guessing somewhere between 75 and 85, according to the data."

"And what happens when I reach zero?"

"Your file doesn't say," the Master muttered, scanning the data. "The lowest reading I see here is 42 percent… but you still have time until you reach that," he added quickly, seeing the look on her face. "And that timeline won't happen, anyway. For now, let's focus on setting up everything we need for our life here."

"O-Okay," Eva said quietly, taking the hand he offered her without giving it too much thought and taking a couple of steps out of the TARDIS with him before he suddenly paused.

"Did he give you a TARDIS key yet?" he questioned.

"Er…" Eva looked at the Master, confused. "No, not yet."

"Well, seeing as it's going to be our house until we can settle on an actual place of our own, you might as well take this," the Master said, searching his top pocket until he found a key and handing it to her. "Now, we have a lot to do but I think it would be best if we head to the bank first, and maybe the hair salon later…"

He kept talking, but Eva was no longer listening. Instead, she looked at the small object in her hand, swallowing down the tears that threatened to fall from her eyes.

She always dreamed about the day the Doctor would finally give her a TARDIS key. She remembered River telling her, back at the Library, that she could open the doors with just a snap of her fingers, but she knew that having her own TARDIS key meant so much more than that. It meant that the Doctor trusted her enough to give her access to the power that came with the TARDIS, it meant he cared for her enough to invite her into his home – and maybe, one day, make it their home as he always called it in his older bodies.

Yes, she had a lot of dreams of the day she would finally have her own TARDIS key.

But in none of them it was the Master giving it to her.
