I arrived in London on a Tuesday, and by Thursday I was growing impatient.

The city was more beautiful than I had anticipated, the architecture held it's own sort of magic. I went sightseeing to all the places I'd dreamed of: the London Eye, Westminster Abbey, Buckingham Palace, and Big Ben to name a few. They were amazing, and mystical, but I felt like I was missing something. I could sense something else around me wherever I went, something hiding just out of sight. I kept catching glimpses of shadows that didn't belong. I would watch them out of the corner of my eye, but as soon as I could get a lock on them they would flutter away.

This has to mean something, I told myself.

After a few days of chasing shadows I decided that I had most definitely lost my mind and should probably admit myself to the nearest psychiatric hospital.

The sun was setting and I was slowly wandering around the city, debating whether to notify my family of my newfound insanity, when suddenly all hell broke loose.

People started screaming and rushing past me, terror etched across their faces.

An older woman knocked into me and shot me a confused and scared look. I was caught up in my own head and it took me a moment to understand what was happening.

"Don't just stand there! RUN!" she screamed before hurtling off again.

Panic started to seep into me just a bit as I twisted, trying to find what everyone was running from.

Is it a terrorist attack? An explosion? I didn't hear anything blow—

The thought died out as my gaze fell on the approaching threat.

They were over six feet tall, slender, and a slimy green. They had four arms, two on each side, and each arm finished with two long, taloned, claws. They ran using their arms to help gain speed, almost hopping down the street.

Even as the fear began to course through me, it was laced with something else… excitement.

This is it, what you have been waiting for. Proof there is more out there. Maybe you aren't crazy after all.

Despite the giddy feeling attempting to overwhelm me, I did realize that these things appeared to be a danger. They were overcoming the running people with ease and striking out with their dangerous claws.

I took a deep breath and darted down the nearest side street. Looking around I spotted a large dumpster and hurried behind it, I needed time to think.

Once safely out of sight, I sank down and buried my head in my hands.

What is going on? Is this really happening, or have I truly lost it?

A loud snarl makes my head pop up. I peek around the edge of the dumpster and see several of those creatures heading down my street.

I need to move.

The following hour is a blur of running, anxiety, and stealth. I made my way through the city, not sure where exactly I was heading, just knowing I needed to keep moving if I wanted to survive. Those things, whatever they were, didn't seem interested in hostages… only casualties.

One street I turned on looked like a warzone. A car crashed into a fire hydrant and water shot into the sky. Debris covered the street. Bits of broken brick were spread out from the side of a smoking building, looking like there might have been an explosion. The air was foggy, but I could still see clear enough.

"Mommy!"

A sharp, young, cry pierced the air followed closely by a guttural growl. My head snapped to the left and I saw a little girl, maybe eight years old, cowered against a building, in the shadow of one of those things.

I didn't see her mother anywhere, and it was clear the creature was about to attack.

"Leave her alone!" I shouted rushing up behind the creature.

It barely spared me a backward glance before reaching one of its arms back and knocking me to the side. I felt a sharp sting on my shoulder where it touched me and looked down to see the slime the thing was covered with, eating through the material of my shirt.

"Help me!" the little girl shouted.

The pain was annoying, but not unbearable, so I ignored it and searched around for a weapon. A few feet from where I was standing lay a three-foot piece of metal piping that looked to have once been a parking meter. I grabbed the metal post and held it like a baseball bat, moving to stand behind the creature.

"I said, leave her alone!" I screamed, swinging the makeshift weapon with all of my might.

It collided with the creature's side, where the ribs should have been, knocking it over. It didn't seem to be unconscious, just disoriented. It sat there, shaking its massive head, trying to regain its bearings.

"Jenna!" someone called from behind me.

A frazzled looking woman in her thirties ran up and scooped the young girl into her arms.

"Thank you," she said, her eyes glazed.

"Of course, but you two had better go. It's getting up," I urged her. "I'll, uh, slow it down. Go!"

The woman gave me a thankful look, murmured another 'thank you' and hurried off with her daughter.

The creature quickly regained its footing, and loomed over me.

"You're not so tough," I assured it, feigning a confidence I didn't feel.

Clicking fangs and snarls were my first warning, but didn't come soon enough. Before I even had the chance to consider running, two more of the creatures flanked on either side of the one advancing towards me. I tightened my grip on the metal pipe and started to back away, slowly.

I swear they grinned at me. Their deformed mouths, filled with gnashing teeth, twisted and conformed into nasty smiles. Black eyes, filled with hatred taunted me, knowing I knew I was a goner. My breath hitched as I backed away.

Take at least one of them with you, I told myself, just as my foot caught a large piece of debris and sent me sprawling onto my backside.

The creature in the middle, the one I had hit, let out a bark of what could only be described as laughter, as I tried to crawl backwards away from their approaching forms.

I saw it raise two of its long arms, four of its razor claws, and held up my arm in a last chance effort to block the coming blow.

Unexpectedly, and making no sense whatsoever, the three creatures burst into green ashes.

What?

My arm fell to my side and I looked up in astonishment. Standing where just moments before those creatures had been, was the man I had been dreaming about for years.

"David Tennant?" I asked, astonished.

"Who?" He asked, and extended a slender arm to help me up.

I took his hand, positive those creatures must have killed me and I was in heaven.

"Aren't you David Tennant?"

"Me? Nooo," he scoffed, "I'm the Doctor. Who are you?"
