I do not own Doctor Who or any of the characters, nor am I gaining any amount of profit or personal gain from this story, other than the rewards of putting pen to paper (or keys to screen) and letting my mind flow free. As far as I know, the general storyline is my own, but if it is not I will graciously accept that it is the work of the wonderful writers of Doctor Who, all of the characters belong to them. Enjoy.

The Devil Inside

Chapter One- Not Myself

My name is Beth. At least, the name I go by. I look fourteen, but my true age tells a different story.

I'm looking for my dad. My true flesh and blood. I used to be happy with him and my mother, a long time ago, on a very different planet. I lost my Mum in a war. Not a normal war. I know that my dad were the only ones to survive it.

This is the story of how I meet him. Beginning to end. The man I haven't seen since I've been locked in a very different time, grieving, escaping, dreaming.

My dad. The man known as the Doctor.

Except... I'm not quite myself.

"Something isn't quite right..." the Doctor murmured, looking at the steadily moving console of the TARDIS, while Amy and Rory looked on nervously.
"Uh, should we even ask what's going on?" Rory asked uncertainly.
"Probably not, since I don't have the answer." the Doctor's voice was muffled as he darted out of sight. Amy nearly jumped out of her skin as there was a loud bang and the Doctor's angry yells. Rory, however, not adapted to the sometimes bumpy ride of the TARDIS, tripped and fell, skidding along the floor. When he had finished cursing and Amy had helped him up, the Doctor faced them.

"OK, who wants a gold star for remembering the rules?" he asked, clapping his hands together.
"Oh, me! Goody!" Amy said sarcastically, glaring at him. "I'd rather be told what the hell just happened." she folded her arms expectantly. The Doctor mentally hit himself for faltering under her gaze.
"Fair enough. Rules first though. Do everything I tell you and don't run off, and..." he looked sheepish. "I've got a new one. Stay calm."
"Why do we need to stay calm?" Rory looked nervous.
"Well, we've crashed into a parallel world where we may or may not be alive and we can't get out at this present time because SOMETHING is overriding my controls and we are at risks of our own minds." the Doctor said all this in a rush.
"Sooo... What do we do?" Amy nibbled her lip and elbowed Rory as he gaped at the Doctor in horrified disbelief. He cleared his throat and tried to stand as if this really didn't bother him at all when inside he was scared out of his wits.
"We either stay in here and hope whoever or whatever is overriding the system's controls stops so we can escape, or we explore outside and hope we find something else to get us out of here."

"I'd go for the latter so I can continue my work here." I said coolly, strutting towards them, my arms folded, face smug.
"A-"
"I'd rather you didn't call me by my first name, Dad." my eyes flashed with anger.
"What happened to you?" he gasped. "You used to be so-"
"So what? So special, so perfect, so nice? A lot's changed then. What a-" I gave a small fake smile. "Pity."
"I don't believe for one second you are A-"
"It's Beth now. Something normal, not out of the ordinary, like you."
"There is no way you're my daughter. Something is happening here, Beth, and I don't know what it is yet but I will get my daughter back." the Doctor supressed tears, trying to channel his emotions into anger instead. The little good I had left, somewhere deep inside me, felt a stab of pain, quickly covered by uncontrollable rage. He was quick to catch on, and he felt like his heart was being ripped out.

"Did you say she was your daughter?" Amy said in a hushed voice.
"Oh, sorry. I should have introduced myself more thoroughly." I simpered. "I'm the Doctor's daughter. He didn't bother looking for me. I've been alive for 607 years and not once has he even thought about me-"
"That's not true!" the Doctor said in anguish.
"I have two hearts, limited regenerating power, a sonic screwdriver, and his hair colour apparently." I eyed his messy dark hair with distaste.

The Doctor stepped forward, and his dark eyes searched mine. I saw the hollow sadness the memories of Gallifrey had scarred him with, the unshed tears that glistened in his eyes.

My own eyes flashed red.

He took a step back, his mouth slightly open. He circled me. I folded my arms, as if I was bored with the whole procedure. I knew he was trying to analyse what was happening. Rory was pale with shock and Amy's face was ashen at her friend's distress.

"Now, you can go outside and try and stop what's happening, which I think you will fail, or you can stay here while I work on destroying your TARDIS. Your choice."

The Doctor looked at me for a moment, closed his eyes briefly, then opened the door of the TARDIS and checked the atmosphere. Then he beckoned for Amy and Rory to follow. The door swung shut and my dark hair blew back, my long black dress fanning out behind me in the momentum of the slight breeze.

Far away across the surface of the planet, the screams began.
