"Stop!" I yelled after the big eared man as I chased him down my apartment building stairs. I glared at the mystery man, not out of hate or anger, but mostly out of annoyance that he wasn't answering my questions. And also because he was making me chase him down bunch of stairs for answers. Rose was close behind me.

"You blew up my job first job here in London! You can't just go swarming off!" I continued to scream at him.

"Yes, I can. This is me swarmin' off." He replied.

"But that plastic thing, it tried to kill you and Ari!" Rose protested from behind me. The man just kept walking away we jogged to catch up.

"It wasn't after you. Why is she called Ari? Is that short for Arianna?" He asked suspiciously. "And where did you get that necklace?" My brain tried to process what he was talking about. My hand flew to my neck and I felt a short cold chain. A round silver stopwatch, nearly two inches wide, was connected to the chain. I stared at the various blue circular patterns engraved into it. Both Rose and the man waited for a response.

"Why should I tell you?" I snapped rudely. Rose, sensing my hostility, decided to take over my little interrogation.

"Who are you?" She asked.

"I told you, I'm the Doctor." He answered in a non-caring manor.

"Doctor what?" Rose asked.

"Is that supposed to be impressive?" I questioned, trying to keep the smile off my face, but I failed terribly. He just shrugged.

"Sor' of." He muttered uncaringly.

"Come on, you can tell us." Rose said.

"I've seen enough. Are you the police?" I demanded.

"No. I was just passing through. I'm a long way from home." The Doctor responded. I cocked my head at them.

"Which is?" Rose asked.

"Oh, just a long way from here." The Doctor bypassed. "Speaking of which, what's with that accent?" My eye twitched at the question.

"I'm American! My god, is that so hard for everyone to get that through their stupid heads…" I began to rant before blushing faintly at the fact that the The Doctor looked like he wanted to laugh at me.

"But what have we done wrong? How comes those plastic things keep coming after me and Ari?" Rose asked, even though it nearly killed me, not her.

"Oh! Suddenly the entire world revolves around you! You were just an accident, you got in the way, that's all." The Doctor argued pointing at Rose.

"Oh that's it, is it?" I muttered sarcastically. "It tried to kill me!"

"It was after me, not you two! Last night, in the shop, I was there, she blundered it. Almost ruined the whole thing. This morning, I was tracking it down, it was tracking me down... the only reason it fixed on you two is that you met me." The Doctor explained.

"So, what you're saying is, the entire world revolves around you."

I rolled my eyes. "You're as much of an egomaniac as Rose's boyfriend Mickey." I muttered and Rose gave me a short glare.

"Sor' of yeah." The man replied.

"You're full of it!" Rose said.

"Sor' of, yeah." The Doctor repeated and I laughed. "But no one else knows about it, so I'm on my own. I mean, you lot, all you do is eat chips, go to bed, and watch telly! When all the time, underneath you, there's a war going on!"

Rose took the arm from the Doctor and tossed it to me. "Okay start from the beginning." Rose commanded.

"Okay, the British set up colonies in the new land for gold and minerals-" I started to explain the history of America.

"No I meant the plastic." She interrupted, slightly amused by my outburst.

"If you're gonna go with this living plastic, and I don't even believe that, but if we do... how did you kill it?" Rose asked.

"The thing controlling it projects life into the arm. I cut off the signal, dead." The Doctor explained.

"Is that radio control?" Rose inquired.

"Thought control." I corrected. Rose looked at me in complete shock, and I had a feeling that the doctor looked the same.

"Are you alright?" He asked looking straight at me.

"Yeah, I don't know where that came from." I answered. "So, who's controlling it, then?"

"Long story." the Doctor said.

"But what's it all for? I mean, department store dummies... what's that about? Is someone trying to take over Britain's shops?" Rose joked. I laughed at the idea and the Doctor laughed as well.

"It's not a price war." The Doctor added. "They want to overthrow the human race and destroy you. Do you believe me?" Part of me believed him, but I wasn't sure why.

"No." Rose answered truthfully. I looked but Rose seemed sure of her answer.

"But you're still listening."

Rose and I stopped as he walked on. My patience grew thin. "Really though, Doctor. Tell me, who are you?" I snapped.

"Do you know like we were saying? About the Earth revolving?" The Doctor walked back towards me. "It's like when you were a kid. The first time they tell you the world's turning and you just can't quite believe it because everything looks like it's standing still. I can feel it the turn of the Earth." The Doctor took Rose's hand and mine.

"The ground beneath our feet is spinning at a thousand miles an hour, and the entire planet is hurtling around the sun at sixty-seven thousand miles an hour, and I can feel it. We're falling through space, you and me. Clinging to the skin of this tiny little world, and if we let go..." He let go of our hands and my eyes snapped open. "That's who I am. Now forget me, Arianna. You too, Rose Tyler. Go home." Then he walked away leaving us speechless.

Rose turned to head back but I stayed for another moment before turning around just in time to miss him leaving.

"Ari?" Rose asked, breaking me out of my thoughts. I shook my head and cleared my throat.

"We need to get answers." I told her.

"Can I use your computer?" Rose asked. I grinned at her nervously and scratched my head.

"I may have accidentally fried the hard drive." Rose looked at me sceptically.

"'Accidentally'?" She stated. In complete honesty, I literally fried the evil thing. It got a computer virus stuck on it and nothing I tried would get it off. So I literally fried the stupid thing.

"We'll have to use Mickey's then." Rose decided after a moment of thought.

"But Rose, he calls me insane!" I whined.

"Well, I'm not really sure that he's wrong about that..." Rose trailed off. My jaw dropped as Rose rolled her eyes at my childness.
