AN: This was just a story that I thought would be cool. If you like it, I will continue. If you don't, I won't. The choice is yours, dear readers.
"My feet hurt" Said Clara as she followed the doctor. "Aren't you even the tiniest bit…incredibly bored?"
"Not a chance" Replied the doctor "All this-it's fascinating"
They were trekking through a muddy forest, passing rows of 'special' trees.
"So, what's special about this tree then?" Asked Clara, stopping at a very normal, thin trunked tree.
"That is the raxachoragafalipatorian peace tree" Explained the doctor, looking insulted.
"And this one?" She said, trying to test him.
"Absolutely nothing, it's just a tree" He said, incredulous.
"What? I was promised a forest full of interesting and important trees" She said in mock horror.
"I never said all of them were interesting and important" He said, trying to justify himself. "Just, most of them"
"Someone carved their initials into it" Clara informed the doctor.
"Good for them" Said the doctor.
"Actually, several people did" she said, now purposely trying to annoy the doctor.
"So?" He asked, stopping and turning around.
"I just thought you should know." She said with a cheeky smile.
The doctor sighed and continued walking.
"AP" Said Clara
The doctor froze. "What did you just say?" Asked the doctor in a suspicious tone.
"That's someone's initials, AP" She repeated.
The doctor walked quickly to her side. His facial expression was a little bit shocked and a lot concerned. The word 'pond' was only just audible as he muttered it under his breath.
"Why" Inquired Clara, "Do you know someone with those initials?" She asked.
"I used to" The doctor said darkly, as if he was purposefully not telling her something.
"What do the other initials say" He asked.
"Well, very close, there is one that say RW, but the W was replaced with a P."
This statement was followed with a sharp intake of breath that sounded to like 'Rory"
"There is MP, but someone scratched it out and wrote RS"
The doctor remained wide eyed and worried. His heartbeat quickened. As his mouth formed the word 'River'
"RT was replaced with BW"
The doctor's eyes lit up a bit as he began to understand. Bad Wolf.
"CJH became FOB" she said. "And for some reason, COO has just been scratched out."
The doctor whispered 'Captain Jack' before he fully comprehended what she had said. He grabbed her arm. "It's not safe here for you, we have to go"
"Why?" asked Clara.
"What did you say about most of those names?" The doctor asked.
"That they were replaced with something else?" Clara said.
"No, that they became something else"
"So what?" Asked Clara, confusion plain on her face.
"So, it's implying that the person changed" He explained, impatiently.
"And I would know, I knew each and every one of the people on that tree."
"Knew?" She asked, feeling slightly scared.
"That's right, past tense." He said, confirming her fears.
"And what was the last initials?" He asked, waiting for her to figure it out.
"COO" she said.
"That's you!" Shouted the doctor.
"But I don't have a middle name!" She said.
"Not yet you don't!" He shouted, pulling the TARDIS door shut behind them. "And the you who has a middle name, is no longer with us"
