1 – The Doctor

As I was wont to do on Saturdays, after my morning cuppa I went for a walk through a park a few blocks from my house. Although it wasn't a particularly large park, it was packed to the brim with trees, bushes, undergrowth, hills, trails to walk on, you name it and it was there, almost to the extent of being a forest in the middle of London. I came here every week because I liked hearing the birds sing, seeing the trees blow in the breeze, and enjoying the company of others that, like myself, appreciated life and nature.

Really, although on a much larger scale, that was the reason I had moved to London in the first place. I was born in California under the name Nelson Downs, and I had never really fit in. When I was twenty-five years old I had gone on vacation to London, and immediately I fell in love with the city, the people, and the lifestyle. A year and a half later, about eight months ago, I packed my bags and moved here. I've been very happy on the whole, but I haven't made any good friends yet, and sometimes I can start to feel quite lonely.

On this particular day during my walk, I didn't see a single other person. Usually there are at least two or three other people walking along the paths, but, although I thought it rather strange, I enjoyed my walk nonetheless. Just as I was turning around to head home, I heard two unfamiliar voices speaking with each other and getting closer. I couldn't hear exactly what they were saying, but soon they had rounded a bend in the path around a dense cluster of bushes and trees and were in my line of sight, about ten feet away.

There were two of them, a man and a young woman. The man was tall, wearing a suit, and had untidy brown hair, while the woman was about a head shorter than he was with shoulder-length blonde hair. Neither saw me at first, as their conversation appeared to be rather involving, but when the woman glanced up she spotted me immediately.

"Doctor," she said, stopping suddenly. "Someone's here."

"What?" he said, looking up at me and squinting slightly. "Why wasn't he evacuated?"

"Excuse me," I said, walking towards them. "Did you say evacuated?"

"Blimey, how does he not know?" the man said amusedly, grinning slightly.

"Listen," the woman said urgently. "It's not safe here, the police have evacuated everyone in a five mile vicinity and surrounded the park, but they should let you out. You've got to go - quickly!"

I blinked, bewildered. "Why?" I asked. "What could there possibly be that's so dangerous in a park?"

"That," the woman said, nodding her head in the direction behind me.

I turned around and immediately recoiled in fright. "Ahh! What is it?"

The creature standing a few yards away from me was tall, very tall, fat, green, and had large bulbous black eyes. It also had a long neck, clawed hands, and appeared to be wearing some kind of device around its neck with a light on it that was both blinking rapidly and making a strange whirring sound.

"That," said the man, "is a Raxacoricofallapatorian. Well, it's a Slitheen. Well . . . It's the last Slitheen."

I stared at him incredulously. "What!" I exclaimed.

"Stay out of this!" the creature snapped. "So, Doctor, you have come to kill the last member of the Slitheen family," it said, looking at the man.

"I don't want to kill you," he replied, stepping forward. All traces of a smile were gone now – he was dead serious. "I have a TARDIS, you know that. Let me take you somewhere you can be safe. Let me help you."

"I think not," the Slitheen, I think it was called, replied. "I know how you help us Slitheens. You tried to kill us all at 10 Downing Street, and you almost succeeded. Blon and I managed to escape, although separately and in such a way that she was unaware I had survived as well. I tried to contact her, but when I used my emergency teleport to escape it drained my communicator's power, leaving me isolated."

"Is that why the thing on your neck is blinking and making a funny noise?" I asked.

"It is kind of a funny noise, isn't it?" the man said, grinning suddenly.

"Yes, actually, it's so annoying to- I SAID STAY OUT OF THIS!" the Slitheen snarled at me. Pausing for a moment, it took a deep breath to calm itself, and then continued. "Anyways, I had just read that Blon was the mayor of Cardiff and was on my way there, but you beat me to it. You got there first, Doctor, and then you killed her. You killed Blon, just like the rest of my family!" it shouted angrily, glaring at the man.

"I did not kill her," the man insisted. "I gave her a chance to have a second life, a better life. Let me do the same for you. Please, let me help you," he said.

"Oh, Doctor," the Slitheen mocked. "Do you really think I'm going to accept your help?"

"It doesn't matter what I think," the man said. "I'm giving you a choice. Will you let me help you?"

There was a pause. "No." In a flash of movement, the Slitheen reached up and pressed the screen of the device it wore around its neck and then, to my horror, began sprinting towards us on all fours. Suddenly, a bright light erupted from all around us, temporarily blinding me, and a roaring sound began to pass over our heads.

"Rose, now!" the man yelled.

"Get down!" the woman shouted, shoving me facedown to the ground. There was another flash of light, a sharp crack, and then the roaring sound faded and died. Shaking, I looked up, expecting to see a scene of utter destruction before me, and was surprised to find the park exactly as normal. There was no Slitheen, the birds were singing, and all of the usual people were walking tranquilly around the park. Indeed, aside from the man and woman still being here, the man now holding a large green egg, and myself being on the ground, everything was just as it always was.

"You can get up now, it's safe," the woman told me, offering her hand. I took it gratefully and, brushing the grass off my clothes, looked around once more.

"How can everything be back to normal?" I asked, stunned.

"Ehh, that's kind of difficult to explain," the man said.

"Are you going to try?"

"Well," he said slowly, thinking. "No." He grinned cheekily at me. "Allons-y!" The man beckoned to the woman to follow him and started walking away.

"Wait!" I said, not about to let them go without answering some questions first. "Who are you?"

The man turned around and started walking backwards. "I'm the Doctor, and this is Rose Tyler. Hello!" Having said this, he turned back around and continued to walk away.

"Yeah, you're a doctor, I caught that. But doctor who?" I yelled after them.

"Just the Doctor," the man called back. The Doctor, what a strange thing to be called without a name attached to it.

And then, making a comment I didn't catch, the Doctor and Rose Tyler laughed and walked around the corner again, leaving me alone.
