Emma's POV

I am not giving up this fight for a simple, stupid headache.

"Now the pole's broken, so it's going to be harder grabbing it," I said, "but her powers have waned a bit. Notice the plague hasn't effected her one bit..." my voice trailed off.

"We should go check on the TARDIS," River suggested. I shrugged and started heading back to the TARDIS. The Doctor followed suit. After a block, we saw the crater of the explosion. The pole of the scythe laid in smitherens around us. The Child laid in the middle, smoking. Part of the blade of the scythe had fallen off. She looked at us, dazed. She twitched and flinched. The Doctor looked at her with pity, but I grabbed his arm to pull him along. "Doctor, there's nothing we can do. Just leave her."

"This is your sister. You'd leave your own sister to die?" he asked. "I say we grab the scythe."

"You go check on the TARDIS. I'll deal with her," I compromised. He shrugged and started, then came back. "Where's the TARDIS again?"

"Down the street. You'd know when you see him. Just follow the sidewalk," I said.

I knelt down by the Child's side. "Why are you doing this?" I asked softly. "This isn't like you."

You don't understand me! You never understand me! I'm sick of laying in your shadow, being bullied because I was weird, insane...

"But you're not," I whispered. "You're my sister. This isn't like you. Nobody understood you better than me. We used to wrestle together, play together... what happened to that?"

I accepted my Fate. And it is to kill you!

"Revenge is never the answer," I whispered, gently trying to tug the scythe out of her grasp. "There's some of my sister in you, I can tell, just let go of the scythe, join your family, this isn't the answer, killing is never the answer..." I was gently crying now, tears hitting the Child's cloaked face. I let go of the scythe, and pulled the cloak off her face and stumbled back in surprise.

Half of her face was obscured by darkness. Don't you see? whispered the Child, You turned into this. And you never thought about it!

I was taken back. How could this be my sister, my own sister... 

I grabbed the scythe and tugged harder. It slid slowly out of her grasp, but before I could pull it completely out, she swung it, sending me flying. I landed on my hands and feet. My left wrist cracked from the impact. I ignored it and charged the Child. I reached for her scythe, but missed. I rolled on the sidewalk. She swung at me, but suddenly stopped and slowly lowered the scythe. Then it hit me: the Child was fighting my sister's soul. She was of two minds- The Child's and my sister's. I could use it to my advantage. The black half of her face flickered, and I could see the other half of her face. I reached for the scythe, and she said, "I can't drop it- she'll kill me!"

She wasn't talking in mental telepathy. I was so shocked by this discovery that I was nearly chopped by the scythe. Kill her!

I realized that when the Child was in control, she spoke mental telepathy. When she was my sister, she spoke with her mouth. That, and half of her face was black- no, it wasn't black, it was empty- when she was the Child, and when she was my sister, I could see her whole face. I waited for her face to appear, then screamed, "Drop the scythe! She can't kill you when you're her body! She's only the scythe! She's only the scythe!"

Her hand began to open, but closed tightly. With her free hand, she ripped her hood over her face. I am her, you fly! I am so much more than a scythe! I am a living being! I controlled your TARDIS into say it was Zeher, then when you and your friends left the TARDIS, I put the book there, to confuse you! I have been keeping your friends TARDIS alive so when you finish the "cure" you had just poisoned her more! I could kill her easy; she would die in a snap when the poison in her system, like every living thing! There is no cure!

"Funny thing," I said, "I knew that. I realized all the things mixed together would create poison, so I threw it out. But the thing is, you are no longer completely in control now. The poison in the TARDIS is sizzling away as we speak. You failed. You're nothing but pathetic, Child, and I just proved it!"

She swung the scythe at me. I grabbed it, and it slid more out of her grasp. I looked in her eye. "Let go, Child. We are not enemies. We are sisters."

You lie! You are as much as my sister as a deer tick!

"Oh yeah?" I asked while tugging the scythe out of the Child's grip. "You're about as annoying as one, I'd say you were related to one. What do you say about that, Child?"

She was distracted. I yanked the scythe to my abdomen, feeling the jagged edge dig into my stomach. "Let go," I snarled through clenched teeth.

Why? So I can be thrown in your shadow again? I'm not stupid, Emma.

"If my name is fake," I asked, "why do you use it?"

Reasons. Let go!

"No!" I screamed. I was locked in a life-or-death game of tug-of-war. The Child spun, trying to shake me off, but I gritted my teeth and held all the tighter.

The half of her face flickered. "Just let go, Emma! Once you hold it-"

The half of her face went empty. Let go, you flea!

"Never," I said.

The side of her face came back. "Once you hold it, Emma, you become her! That's what-"

The half went empty again. It was horrific to watch her face flicker on and off, about as disgusting as the smell coming off of her. I kicked her in the face, and she let go...

Doctor's POV

I watched as the poison slowly sizzled off the TARDIS. Emma must of have removed the scythe!

I entered the TARDIS cautiously. There she was, looking as, well, like she always did. I took the TARDIS for a test run. When she landed, I looked outside at where we landed.

And a terrifying sight met my eyes.

A girl, dressed like the Child, but looked like a miniature Emma, was staring at something. I followed her gaze, and I realized that even if my TARDIS was no longer poisoned, nothing was alright.

Emma was floating in the air, mouth stretched in a scream, light surrounding her, sickly yellow light, the scythe in one hand. I began to rush forward, but the girl yelled, "STOP!"

I looked at her. "What's wrong with her?" I asked.

"The Child," she explained. "She lives in the scythe. I tried to warn her, but she failed to let go, and, well, now the Child has a new host."

I stared at her. "Who are you?"

"Crystal Lair, sister of Emma."
