I woke up on the floor of the tardis my hands untied. My mind felt free. I found some clothes on the floor next to me with a note. It read 'Sarah, thought you wouldn't want to wear a hospital gown all day. I have gone in search of the voice in your mind, if that makes sense. Don't follow me under any circumstances. Doctor' As I dressed I remembered how the Doctor had attacked me, no wait how the doctor had tried to save me from fading away and how I had attacked him. Convinced he was a clone. All of it seems so obvious now, I get what he was trying to say. But why did I bite him. I realised I tasted blood in my mouth. I ran to the bathroom and rinsed my mouth out. When I got back to the control room I heard a scuffling outside the door. Don't follow me, he had said. He wished. I noticed his sonic was still on the side. I grabbed it and went out the door to find myself face with two doctors.

"Sarah" one shouted fending off the other "Zap the clone with the third button down it will disable it"

"No" shouted the other grabbing at a scarf "That's the laser ray it will kill me I'm the real doctor"

"don't listen to him Sarah, I'm the real one" said the other. Well this is just great. Which one do I zap. There's no way of telling which one I which unless…

"Stop both of you" I shouted, causing them to halt in surprise. I held the sonic device against my head my hand trembling, my finger on the third button down. "I'll press it I really will" If the first doctor had been telling the truth this should do no harm to me, except perhaps a headache.

"No Sarah don't" said Doctor number two "it will kill you"

The other doctor just stood there and pulled out a yo-yo. He started yo-ing. Well that got me nowhere I thought. Then I noticed he was yo-ing in Morse code. Second button down will knock you and clone out I will wake you. Red jelly baby, hurt leg. He finished off with. Those two last things would be things only the real doctor knew. I moved my finger up one and pressed the button. A terrible ringing filled my head and I fell to the floor gasping for breath as the world around me fell into a fog.
