"Doctor why are we crashing!" I was shouting over the loud sounds of metal bending, fires burning and the frantic sound of buttons being pressed.

"I can't remember! Ally, this is going to hurt."

"What's going to hurt?"

Instead of answers my core muscles exploded in pain followed by immediate heart burn. My eyes were blinded by a light that I was sure was definitely not there before. I was like that for who knows how long until it faded slightly and I heard an unfamiliar voice saying something about legs. My eyesight came back for a moment and another light, similar to the one before shone and a whirring whooshing sound began. I collapsed sideways on one of the chairs beside me. My hair fell across my face and I was sure I was blonde a minute ago? No time for that. "We're still crashing!"

"We're not crashing." The words echoed around until I realised they weren't pointed at me. There was no one else in the control room and everything was in pristine condition. There was no evidence of the crash, which I was beginning to think I'd imagined. "Rose where are you?" There were footsteps on the grating I wasn't familiar with. It was Rose I think but I'd never actually met her. She must have thought he was up here.

"Doctor, I think you're going to want to come up here!"

"This had better be important I was about mend the... Who are you?" He didn't recognise me. Of course he didn't recognise me, I shouldn't be an idiot. I could be who knows where in this existence, we might never have even met for all I knew.

"Ally. I'm, I'm Ally."

"You can't be Ally, I just left Ally. Wait, the problem with the sensors earlier. Come here."

"Just to warn you, don't kick anything."

"What, why? What's kicking things got to do with anything?"

He used his sonic screwdriver on me, I knew what it would say. "I'll explain later. Just promise me you won't kick anything?" I relished the confused look he was making. I glanced at the screwdriver and noticed the tiny section that said I had a tiny bit of his DNA in me. It wasn't there when I still lived on Earth.

"Excuse me, still here by the way but who's Ally?" We'd forgotten about Rose.

The Doctor ran a hand over his face. "Oh right. Ally is.."

"I'm the resident teenager, nice to meet you." I got more than one surprised look at that.

"Since when did you live with me?"

"Since four years ago when this got really complicated." Going from how old I think I was in this time frame it was already complicated but he has no idea what's coming for him. I was probably twelve at the moment and not long come back from Omaria. I looked down at my singed clothes. "Can I go get changed?"

"I'll come with you." Rose and I went down to the wardrobe. I owed her an explanation. "He's never mentioned me has he?"

"Are you another one of his companions? I always wondered why he would keep running off every now and then. He must have a thing for you."

"I never used to travel with him. In fact at the moment I've probably been in here once and I freaked out. Kept calling it a tin can to begin with." I laughed cruelly at my existence back then. Back now, whatever this is shouldn't have happened. "I told you not to kick anything!" I shouted at the one person I couldn't see while hopping slightly. A confused Rose went back to the conversation.

"But you travel with him now."

"Only because I'm forced to. We went back home when I was fifteen to get some chips and things got really painful. I was on the missing persons list and..." I stopped before I said to much.

"He still likes chips?"

"More like I wanted chips. I guess? It isn't something we eat regularly."

"Why did you start hopping and tell the Doctor off for kicking something?"

"It's complicated."

"I like complicated."

"I know, they all like complicated. And the running, everyone likes the running." I finally found the t-shirt I wanted and some jeans. I changed in what would eventually be mine and the Doctors room and looked in the mirror. I looked the same as I ever did. Apart from a strip of black hair That wasn't there before. I thought something had happened to my hair.

"I just told you not to kick anything!" I mumbled idiot under my breath.

"I didn't kick anything." He called, wounded. But if he didn't kick anything and I didn't kick anything and I am absolutely sure that felt like when the Doctor kicks something when someone does something he said exactly not to do... I ran to the kitchen and grabbed a knife. I hoped this would work otherwise I'd be putting myself through this for nothing. I began to etch in my skin.

"What the heck are you doing? Put it down!" The Doctor must have been looking for me.

"No. If it's the only way..." Blood began to run down my arm. I finished the S and began on the T. The Doctor grabbed the knife away from me. "You don't understand. If this works there may be a chance that I can send a message to him!"

"What's going on?" Now Rose had to enter the room.

"She's cutting herself."

"For a very good reason." I growled.

Rose looked horrified.

"The scars won't be there for long, if there are any. Now give me my knife!" There was a reasonable amount of scrapping around in which I lost terribly to the Doctor and Rose.

"What are you trying to get out of this Ally? Freedom from something."

"I'm trying to send the other you a bloody message. Right now all he's got is some blood on his arm and an S! At least I think he has."

"What!" So much confusion. I love that face but I didn't know if I liked it right at that moment.

"Give me the bloody knife!"
