Ooooooo. Chapter 13... Yeah, I'm totally going to use this opportunity and do something horrible. (Even though technically, this is chapter 14, but it's thirteen because... yeah... math stuff. You figure it out.)
The Doctor
After choosing a path, the Doctor led the Pond and River down the stony hallway. This path didn't have any twist or turns, but finally it ended, a single door blocking the way. The Doctor pulled out his sonic and scanned the door while the Ponds and River talked about something in hushed tones behind his back. The scan showed that the door was just a regular door made out of wood.
Tentatively, the Doctor reached for the door knob. When he came into contact with it he expected something, anything, but nothing happened. It seemed like a normal door knob.
Slowly, the Doctor twisted the knob and pushed open the door.
The Ponds
As the Doctor pushed the door open, the Ponds stopped their whispered conversation and they all stared into the empty darkness that the door revealed.
"Rory?" Amy whispered. The Doctor turned and faced her and placed his finger on his lips, mimicking the quiet gesture. Amy closed her mouth and stared at the Doctor. He turned back to the door and walked forward slowly.
Amy, Rory and River followed, inching along until all of them were inside. There was no source of light at all and the room seemed to stretch on forever.
As soon as Rory opened his mouth to say something, the door slammed shut behind them, engulfing them in total darkness. He heard River gasp behind him and somebody, most likely Amy, grabbing his arm.
"Rory? What's happening?" Amy whispered in his ear.
"I don't know." He whispered back "Maybe-" But his words were cut off as lights appeared, painfully replacing the darkness with blinding light. The Ponds, River and the Doctor all dropped to the floor, covering their eyes.
"Don't you see, Doctor? Every creature that has been in the dark long enough will shy away from the light." A young girl's voice said, echoing through the halls. Rory tried to look up to see who was talking but his eyes still hadn't adjusted to the light and he covered his eyes to block out the brightness of a thousand suns.
To his right, the Doctor said something loud in Gallifreyan. The little girl, or whoever it was, must have been able to understand him because she giggled. A giggle that sounded like it came straight from a horror movie.
"No, they can't." She said. The Doctor responded and Rory thought that he might be able to look up without burning his irises. He slowly rose his head and opened his eyes. It still burned but after a few blinks Rory could at least open his eyes without being completely blind.
Looking around, the Roman saw that the little girl was nothing more than a blurred image at the other end of the room. He blinked again a few times and she came more into focus, but not enough for Rory to see who it was. She was just too far away for him to see.
Rory looked away from the little and saw that the room they were in was simple massive. The walls, floor and ceiling were painfully modern white and only added to his growing headache. He turned to look at Amy and River and found that they were also getting used to the light.
"It depends..." The little girl said, still talking to the Doctor. "What will you do for me?"
The Doctor said something back and the little girl came closer. Rory and Amy started to step back, but River and the Doctor stood their ground.
"Do you even remember what you did to me, Time Lord?" The little girl said in an accusing voice as she came to a stop in the middle of the room. "Don't tell me you've forgotten. Don't you DARE!" She yelled, the lights dimming as her voice changed into a cry of a thousand.
The Doctor said something back in a brave tone, something that the little girl didn't appear to like, because she scrunched up her nose, like she was disgusted and she scoffed.
"Really?! Did you even think before you do things? How would you feel to be cut off from everything that ever kept you sane?!" She screeched, lights once more dimming almost to a point where they were completely off before returning to normal. She grimaced and took a deep breath in. The Doctor said something in a soft tone.
"I'm different now, Doctor, and I've changed my mind." The little girl said and she held out her hand. Suddenly the Doctor was thrown through the air like a rag doll and he hit the opposite wall with a mighty thud and slid to the ground.
He got up immediately and half ran, half limped back to the Ponds and River. Before he could even get halfway to them a wall of glass popped up and the Doctor ran face first into it. He got back up and started pounding on the glass, screaming something.
"I'm done playing games now." The little girl said with a menacing demonic voice and the area which the Doctor was in started to fill with thick black smoke. She turned to the Ponds and River, hand outstretched. "I am done."
Oh, my. That was longer than I wanted it to be, but it was too good to stop. What's going to happen now? What's that black smoke that is surrounding the Doctor? Is it poisonous gas? (Yes) Oh, dear! Will they escape the wrath of the little girl? Who is she anyway? Remember, if you think you know, PM me the answer. I had some really good guess so far, but none of them hit the bullseye. For those that have already guessed, I'll give a little hit. This villain is a lot older...
