The Doctor walked into an old playroom. Worn dolls thrown across the floor along with dusty, wooden blocks, a broken tea set. Everything seemed sad, old, and gray. Literally, gray. "What have we here?" He peered around the room.
"Who are you?" A voice, nearly a squeak, came from behind. The Doctor turned around and saw a little girl, about the age of six, in a blue dress, black hair done up in high pigtails, and her eyes…exactly like Charlie's. Blue as twinkling sapphires in the moonlight.
"I should say the same thing. What are you doing here all alone by yourself?"
"This is my playroom. I'm not supposed to talk to strangers." The girl stepped back in fear.
"I'm not a stranger. I'm the Doctor." He bent down to her eye level.
"Another one?" The girl tilted her head. "You're the eighth one I've seen so far."
"What are you talking about eighth? Who are you? And why do you look so familiar?"
"I thought doctors were supposed to know everything. You ask a lot of questions. You're like the other doctors, too, aren't you? You can't help because you don't anything!" The little girl became grumpy.
Charlie and the blood-covered man appeared behind a sheet a glass, unknown to the little girl or the Doctor. "Where are we?" Charlie scanned the room for a second, "Oh…and that's?" Charlie noticed the little girl getting huffy. "Oh, you've got to be kidding."
"Yes, this is fun, Chuckie." The man chuckled.
"You're not helping." Charlie retorted, "Why are you showing me this?"
"Chuckie, do you want the Doctor to find out for himself or are you going to tell him? Sooner or later, he's going to find out. You're just causing more grief for yourself."
"If you think tapping into my head will gather up my courage, you're dead wrong. I can't tell him because…I just can't."
"Do I have to get involved in this, Chuckie? You'll never grow up if you keep hiding!"
"Hiding is what I do best, along with hiding my secrets. I am not going to tell the Doctor." Charlie seemed furious at the man.
"Then you leave me no choice." The man disappeared from Charlie, leaving her alone.
"Hey, no need to get all fussy at me." The Doctor rubbed his hand against the girl's arm. "I'm better than other doctors. What was it that they didn't know?"
"They didn't know how to make him better."
"Who?"
"He's in the other room. I'll show you." The girl opened a door and went through it.
Charlie rapped her hand on the glass, trying to catch the Doctor's attention, "Doctor! Doctor!"
The Doctor turned his head and there was Charlie, on the other side of the glass, "Charlotte, where the hell are you?" He pulled out his sonic and scanned the glass.
"Don't follow her." Charlie frantically shook her head.
"What?"
"Don't follow her!" She shouted loud enough for the Doctor to hear her.
The little girl came back through the door, "I forgot. You asked me my name, it's Charlotte."
The Doctor looked at the little girl and back at Charlie, whose face never seemed angrier than he ever saw anyone, "Charlie?" He seemed worried.
"You…will never know." Charlie gritted her teeth and in a flash she was gone.
"Charlotte, what are you hiding?" The Doctor whispered.
