Right last night I got this idea down below at 1am. I have no idea were it's going or even if I should continue with it so I'm going to post the start of it on here, so tell me what you think!
"How does it feel Doctor…" the voice echoed throughout the Tardis for, to the Doctor, seemed like the hundredth time. "To see each one of your companions, friends, even lovers, suffer right before your eyes…" The voice paused to laugh, a laugh that made the Doctor tremble with fear. "…Over and over again!"
"Stop this…" The Doctor said through clenched teeth. The pain of all these memories that he had always tried to push away, to the back of his mind were coming back to him. He was on the floor of the Tardis, gripping his head in pain. He saw all of his companions before his eyes again. Each one, screaming in fear, crying out his name, screaming in pain and some of them dieing right before his eyes over and over again. What was this thing?
"You're the smart one…" the voice was icy cold. "Stop all of this yourself! All of these people risked their lives for you Doctor, and they end up helpless at times, they die to help you!"
"But I tried!" he screamed. "I tried to help them! But I couldn't!"
Another cold laugh. "Now nobody's going to be here to help you!"
Review and let me know if I should keep it like that or continue.
