AN: This is my first story for Doctor Who. I hope you all enjoy it. I only own Ali Carter.

Chapter One: The Hospital on the Moon

I remember seeing a bright white light, and the sensation of falling. It felt like my entire body was on fire. I have no idea how long the pain lasted, but it felt like an eternity, when I opened my eyes I discovered that I was lying on a hospital bed. I groaned as I sat up. What the hell had happened to me? I yanked off the thin blanket that was covering me and swung my legs over the side of the bed, the floor felt ice cold to my bare feet as I quietly made my way over to the door of my hospital room. There was a thin dark blue short sleeved house coat hanging from a hook, I quickly put that on over my hospital gown.

Before I could leave the room there was a flash of light and then the whole building started to shake violently. I was flung to the floor and I curled myself into the fetal position. I groaned. First, I end up in the hospital, and now an earthquake is happening. Could this day get any worse?

When building stopped shaking, I slowly got back up on my feet. I exited the room to see that the entire hospital was in a state of panic. What the hell was going on? What had happened to me? I really need to find some answers. I looked to my right and I noticed a sign with an arrow pointing to where the patient's lounge was located. I headed off into that direction and eventfully I came to a set of doors leading to a balcony.

Apparently, I wasn't the first person to have the idea of coming out here, because there was a young black woman in a white doctor's coat, she looked to be an inch or two taller than me, and a tall skinny man wearing a blue suit and some red converses. They both turned around and spotted me at the sound of the doors opening. The woman taking in my hospital gown took a few steps toward me.

"You're one of the patients, yeah?" she asked in a British accent.

Wait, what? Was I in a hospital in England? How did I end up in England? I was in St. Louis, Missouri, on vaction.

I nodded my head, in shock.

The woman smiled at me. "My name is Martha Jones. What's your name?"

"Alix Carter, but you can just call me Ali," I replied.

"Listen, Ali. You should probably go back inside. Everything will be sorted out, and you will be fine, I promise," said Martha.

"Look, I don't remember how I even ended up in this hospital. I just want to know where I am…" I trailed off when I saw the freaking earth in the night sky.

I was on the moon.

"How is this even possible?" I said out loud to myself.

I finally noticed that the man in the blue suit hadn't said a word and was just staring at me with his brown eyes. What a wierdo, even though I did find him just a little bit attractive.

"I promise you, Mr. Smith and Miss Carter, we will find a way out. If we can travel to the moon, then we can travel back. There has to be a way," said Martha, sounding very sure of herself.

"It's not Smith, that's not my real name," stated the man.

Ooh, how mysterious!

"What is your name?" I asked him, curiously.

"I'm the Doctor."

Martha laughed a little at that. "Me too, if I can pass my exams. What is it, then, Doctor Smith?"

"Just the Doctor."

Martha scrunched her face in confusion. "What, people call you 'the Doctor'?"

The Doctor responded "Yeah."

"Well, I'm not. As far as I'm concerned, you've got to earn that title," said Martha.

The Doctor sighed. "Well, I'd better make a start, then."

I watched him pick up a pebble and fling it over the balcony. The pebble hit a blue force field surrounding the whole hospital.

"Just as I thought, there's a force field keeping the air in," said the Doctor.

"If that's like a bubble sealing us in, that means this is all the air we've got. What happens when it runs out?" asked Martha.

I rolled my eyes. We'll suffocate, duh.

"How many people are in this hospital?" questioned the Doctor.

Martha shrugged. "I don't know, a thousand?"

"One thousand people. Suffocating," stated the Doctor.

I shuddered. "That's horrible!"

Martha looked disgusted at the idea. "Why would anyone do that?"

At that moment I heard the sound of engines from above. I looked up to see three gigantic cylinder shaped space ships about to land on the moon.

"Head's up! Ask them yourself," said the Doctor.

"Oh, good! You can see them, too. For a moment, there, I thought I was just insane," I joked.

The Doctor and Martha both smiled at my remark.

Sweet! I think just made two new friends on the moon. Do I have skills, or what?

The Doctor, Martha, and I all watched as rhino looking aliens marched toward the hospital.

Martha gasped at the sight of them. "Aliens! Those are real proper aliens!"

"Judoon," said the Doctor.

I looked at him, feeling confused. Hang on, how does he know what they're called? There's definitely more to this Doctor than great hair and a nice blue suit.

A few minutes later, my new friends and I were on the second floor above the lobby, hidden behind some potted plants. We were watching the Judoon scan people and making sure that they were human. After they were done scanning the person, they marked their hand before moving on to the next one. What the hell were these aliens up to?

"Oh, look down there; you've got a little shop. I like a little shop," the Doctor exclaimed.

I snorted at him. "Wow, you've got a serious case of ADD."

The Doctor rolled his eyes at me. Martha agreed with my statement. "Never mind that! What are Judoon?"

"Galactic police. Well, police for hire. More like interplanetary thugs," answered the Doctor.

"So…" I drawled, "They're basically alien mercenaries."

"Yup," the Doctor responded.

"Great," I muttered, sarcastically.

I saw the corner of the Doctor's mouth twitch slightly upwards at my comment.

"And they brought us to the moon?" questioned Martha.

"Neutral territory. According to galactic law, they've got no jurisdiction over the Earth, and they isolated us. That rain? Lighting? That was them, using an H20 scoop, "said the Doctor.

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

"That can't be right; they're the one that brought us here in the first place," I argued.

The Doctor agreed with me. "No. But I like that. Good thinking. They're making a catalogue; it means they're after something non-human, which is very bad news for me."

I stared at him in shock. "Shit!"

"Oi, don't swear!" the Doctor scolded at me.

I simply rolled my eyes at him.

Martha's eyes widened in disbelief. "You've got to be kidding me."

The Doctor raises one of his eye brows.

"Don't be ridiculous. Stop, looking at me like that," said Martha.

I'm also having hard time believing that the Doctor is an alien. I mean he just looks human, and not weird looking, like the Judoon.

"What type of alien are you, Doctor?" I asked him.

The Doctor just ignored my question and said. "Come on, then."

I sighed unhappily. Fine, don't answer my question. It's not like I meet aliens on the moon, every day. I thought sarcastically as Martha and I got up to follow the Doctor.

The three of us made our way up the stairs.

"So, what are we going to do, now?" I asked out loud.

"I need get access to a computer," stated the Doctor.

"There should be an office on the third floor," added Martha.

I watched the Doctor from the other side of the small office while I was sitting on a comfy swivel chair. Martha was gone for the moment, she had left to go find out what floor the Judoon were on. The Doctor immediately put on some brown colored glasses and pulled out a cylinder shaped device.

I gaped at him. Yeah, that technology definitely looks weird and alien. Before I could ask the Doctor the name of the device that he was using, Martha came back into the room.

"They've reached the third floor," she motioned to the devise that was in the Doctor's hand, "What's that thing?"

"Sonic screwdriver," said the Doctor.

"I think it looks cool," I told the Doctor.

He beamed at me. "Thanks, Ali!"

I looked down so he wouldn't see wouldn't see my now slightly pink cheeks. For some reason I liked the way he said my name.

Martha rolled her eyes. "Well, if you're not going to answer me properly."

"No, really, it is. It's a screwdriver, and it's sonic," the Doctor held it out in front of us, "look."

"What else have you got? A laser spanner?" said Martha sarcastically.

The Doctor didn't pay any attention to Martha's sarcasm. "I did, but it was stolen by Emily Pankhurst, cheeky woman." He angrily smacked the computer, looking frustrated he ran his fingers through his short brown hair, making it look really messy.

I looked at the Doctor's hair, feeling jealous that this man had better hair than I did at the moment. I really wished that I had a scrunchie to pull my own wavy chestnut brown hair into a ponytail. I've always hated having my hair hanging in my face.

The Doctor continued on. "Oh, this computer! The Judoon must have locked it down. Judoon platoon upon the moon," he muttered. "Cause I was just traveling past, I swear, I was just wandering, I wasn't looking for trouble, honestly, I wasn't, but noticed these plasma coils around the hospital, and that lighting, that's plasma coils, been building up for two days now, so I checked in, I thought something was going on the inside, it turns out the plasma coils were the Judoon up above."

"It sounds like you do this investigative stuff all the time," I said to the Doctor.

"Well… almost every day," he drawled out.

"But what are they looking for?" questioned Martha.

The Doctor went back to tinker with the computer. "Something that looks human, but isn't."

"Like you. Apparently," stated Martha.

"Like me. But not me."

"Don't they have a photo?" I asked feeling confused.

"It might be a shape-changer," answered the Doctor, still messing with the computer.

"Whatever it is, can't you leave the Judoon to find it?" grilled Martha.

"If they declare the hospital harboring a fugitive, they'll sentence it to execution," replied the Doctor.

Oh, great, so much for the Judoon being nice aliens.

"All of us?" inquired Martha.

"Oh yes. If I can just find this thing first…" he lightly smacked the side of the computer, "Oh! They're thick. The Judoon are thick. They wiped the records." The Doctor leaned back in his chair. "Oh, that's clever."

"What are we looking for?" asked Martha.

"I don't know. Any patient admitted in the past week with unusual symptoms." The Doctor went back to working on the computer. "Maybe there's a back- up."

"Just keep working. I'll go ask Mr. Stoker, he might know," said Martha as she ran out of the room.

The Doctor stopped messing with the computer for a moment; he looked at me, curiously. "Ali, what were you admitted for?"

Why was he asking me this? Does he think that I'm the alien fugitive? I'm pretty sure that I'm human, but suddenly I had this uneasy feeling that I'm not anymore.

"I don't remember how I ended up here. I was in St. Louis, and then I just woke up in the hospital," I said honestly.

The Doctor sprung to his feet, stood on front of me, and pointed his sonic screwdriver at me. The tip of the sonic flashed blue, and it made a strange noise.

"Are you scanning me with that thing?" I asked.

The Doctor ignored my question, and looked at his sonic with a thoughtful expression. "Well… that's interesting."

"What's interesting?" I narrowed my eyes at him.

"Nothing," the Doctor said quickly. "You're fine. Everything is fine, though you could eat less junk food."

"Hey!" I cried out. "Watch it, E.T!"

The Doctor just smiled cheekily at me.
