"What is it?" I asked cautiously to my cousins, Sam and Dean Winchester.

Dean sighed and shrugged. "Honestly, Ari, I don't know."

Sam looked at the computer and cleared his throat. "Um, whatever it is, it is very dangerous. I know that much."

Dean slapped the back of his hand on the table. "Well of course, Sammy! What else would it be?"

Sam gave Dean an annoyed look. I stepped in between them. "Let me look at it."

The computer showed signs of something powerful appearing in random places throughout time. I bit my lip and tried to find something familiar. Then something flashed across the screen and my eyes widened. Luckily, Sam and Dean were distracted so I quickly closed the computer. I turned to them and sighed.

"I couldn't find anything."

They turned around and walked to their bedrooms in the bunker. I relaxed and turned back to the computer and opened it. I looked closer at the information. I recognized it. This was something I never told Sam or Dean. This was something that was very special to me. This was a part of me. I watched the familiar blue box flash across the screen.

It all started with him. The Doctor. He was my best friend. He was my whole life. I traveled with him for what seemed like forever. I was more than just a companion to him. I was his best friend, too. He was my escape from the world I was living in.

Things happened when I traveled with him. I came face to face with my worst nightmare and I had to leave the Doctor. I was alone in the world with no family. Fortunately, my cousins came to me when there was a case near me. I've been with them ever since.

But something just isn't right. I'm afraid that my cousins will track down the Doctor and expose him for who he really is. I'm just not sure what will happen.

Sam and Dean tried to track down this thing they were following. Dean was especially worried about it. I overheard him talking to Sam about it.

"I'm just worried about Ari. I think she's hiding something from us about this thing."

I heard Sam sigh. "Dean, I think that if she wanted to tell us, she would."

"Sam, what if she's protecting this thing. Who knows how dangerous it is. It could kill her."

That's when I intervened. They acted as if nothing was wrong after that, but I'm sure they're still suspicious about it.

One day, when I was in my room, I heard Dean yell. I ran into the main room and saw Dean grinning. He saw me and his grin faltered just a little bit but he tried to hide it. Sam ran up behind me and Dean's grin widened.

"I found it."
