Prologue: Meeting at 221b

Kira gave a great heaving gasp as her eyes shot open. Her body was burning. She wasn't sure how, or why, but it was burning. And it hurt. She twisted and turned, barely noticing that she was no longer in Platform One with the Doctor, instead she was traveling through the vortex, time and space twisting and forming around her. She burned gold as she fell through the vortex passing out from the pain of it all.

John Watson's POV

It was a normal day at baker street, or as normal as it could get with Sherlock around. Sherlock and I were sitting in the living room, I had just gotten back from shopping as Sherlock browsed the computer, while, my computer. I had just sat down in my chair, thinking of a way to ask him if I could borrow some money to pay the bills when a bright golden light filled the room. Just as quickly as the light appeared it disappeared, leaving behind a young girl.

The girl looked to be about 4 or 5 years of age with long straight brown hair and freckles dusting her cheeks. She was wearing a purple sweater that ended somewhere around the center of her stomach with a blue tank top underneath. Dark blue shorts with rose's printed all over them and a utility belt of sorts holding them up and thigh high socks that looked like a quilt with all the different colors and patterns stitched together finished off with brown boots that reached her calf. The girl collapsed onto the floor, and shuddered a bit. I was stunned, unable to do anything other than stare, and I was happy to see that Sherlock shared my shock.

It wasn't until Mrs. Hudson entered to room, looking at the girl with worried, wide eyes and mentioning a loud thump that I snapped out of my initial shock and moved to help Mrs. Hudson set the girl on the couch. I set a thin blanket on her and checked her pulse before leaving to go get a wet washcloth to help cool her down. The poor girls pulse was far too fast and erratic to be healthy, and for some reason she was burning up, probably what ever caused her to appear in that golden light

Once I was convinced that the child was as comfortable as she could be I settled down in the last free chair and waited for her to wake up. As I waited I watched the girl toss and turn in her sleep, her face scrunched up like she was having a bad dream. About an hour pass when she finally woke up. I waited to let her get accustomed to her surroundings before going to introduce myself and asking her how she'd gotten here. She might be a child, but she must have some idea of how she'd gotten here, some explanation.

Kira's POV

I woke with a groan, though my voice was a far too high pitched to be my own. I slowly opened my eyes and looked around. First thing I noticed was that I was laying on a rather large couch, and I had something wet on my forehead. I moved to sit up, but found myself tangled in a dark blue blanket. After a moment of struggle I finally got my arms free and noticed something disastrous.

My hands were too small to be my own. Infact, if I was to guess I'd say my hands were about as small as a 5 year old Childs. I had barely gotten my upper body free from the confines of my cloth prison when a very familiar face made it's way into my field of vision. I stopped struggling to get out of the blanket wrapped around me as I stared up at the face of none-other than Martin Freemen, or John Watson if his sweater was anything to go by. He looked down at me with concern clear in his eyes as he moved to set his hand against my forehead, removing the wet thing, which I could now see was a wash cloth, as he did so.

"Hmm, well it seems that you're temperature has finally dropped." John said, his tone just as worried as his eyes. He moved his hand down and grabbed my wrist, timing my heartbeat. "But you're heart is still going far to fast and erratic to be healthy. You might need to take a trip to the hospital Princess." John said, his gaze moving from my wrist to my eyes. I tilted my head and idly wondered why he seemed so tall and big. That is, until he asked his next question.

"Princess, can you tell me your name and how old you are?" That was when it occurred to me that he wasn't tall, I was just short. And the reason why my hands were so small and chubby was because they were a Childs hands. I moved to push the rest of the blanket off of my lower body but John stopped me with a hand on my own. "Is everything okay? Can you talk?" He asked. It seemed like John didn't know what to make of me.

"Um, I'm Kira. And last I checked I was 17 years old." I answered, watching in amusement as John's eyes widened in surprise at that statement. It seemed like he didn't believe me. "Um, I mean. I know I look younger, but trust me, I've lived for at least 17 years." I added.

John laughed a moment at the insanity of the idea, but stopped when his eyes met mine. I guess he saw something. He paused a moment, staring at my eyes and assessing my face to see if I could be lying. After the moment's pause he kneeled down in front of me, a very serious look on his face.

"Kira, I can believe you, if you explain to me how. I mean, there's got to be a rational explanation for all of this." John said. I wondered if that was true, if he would really believe me, but I guess spending as much time as he did with Sherlock made the impossible seem possible. With a heavy sigh I thought about all the possibilities.

"Well, I'm sure it had to do with how I got here. I mean, I shouldn't even be here. Well, It's not like I should have been where I was before I was here but after being there being here is even more unlikely." I rambled on, trying to work everything out in my head when an idea came to mind. I turned towards John, who currently looked very confused, and asked the first question that came to mind.

"John, how did I get here? Was there anything odd about the way I appeared?" I asked, curious. If I was right, that could explain everything and maybe more. John scratched the side of his head as he seemed to think about this.

"Well, you did appear in a flash of golden light." John answered, a little hesitant. That seemed to do the trick. Possibilities seemed to rush into my mind like a wave after a broken dam. My mind was moving rapidly from possibility to possibility without stop. I remembered leaving the Doctor in a golden light, burning through the vortex as time and space moved around me. I remembered the pain in my chest along with the pounding in my skull. And it all made sense.

"I think I know what happened!" I yelled out, causing John to jump a bit. "I must have been traveling through the Vortex! All of time and space moving around me must have changed my physical age! Oh it all makes so much sense now! But, it shouldn't. It shouldn't make sense at all. Maybe something else changed, maybe it changed my DNA as well. What was that you said? About my heartbeat being too fast and erratic?" I asked, finally stopping my ramble. John just nodded his head slowly, like he was a bit lost trying to listen to me. "Well then, did you just check through my pulse point or did you use a stethoscope?" I continued my questioning. If I was right, and oh how I hoped I was right, then that could be the most important detail.

"Uh, pulse point. Why? Does it matter?" John asked, obviously confused by my rambling and seemingly random questions. Instead of answering him I simply moved my hands to my chest, slightly surprised by how flat it was, but pushing that shock to the back of my mind so I could focus on the most important part. My heartbeat, or heartsbeat as it were. I had two. Two hearts, a larger, or at least more developed brain and if I'm right, I should have a respiratory bypass system. Oh that was just, that was just fantastic!

"Oh Dear Doctor John Watson it makes all the difference. All the difference in the world. You see, It's not that I've got an erratic heartbeat. Rather, it's I have two hearts. Two separate hearts beating in my chest. And do you know what that means? Oh what am I talking about, of course you don't. I'm a TimeLord. Or is it TimeLady? I suppose it's all up to the persons preference. Hmm, I'll be a TimeLady. That way it's stays as it should be, the Doctor being the last of the TimeLords. But how did I become one? Was it just the strain of traveling through the vortex? Oh no, that can't be right, I was changing before I traveled here. Maybe I've always been one? Oh well, that's a question for another day I suppose. Oh, I guess I'm getting off topic aren't I. Well then, back on topic. I think I changed, I became younger that is, due to the instability of a single person traveling through the time vortex without a case or 'ride' if you will. Traveling through time and space put too much stress on my body, so my body changed to compensate." I finished my explanation. Or, what was meant to be an explanation. John looked positively lost. I was about to try explaining again when a voice interrupted me.

"So your reasoning for being so young when you're not suppose to be is that the Time Vortex changed you? And I suppose you expect us to know what this Time Vortex is don't you Ms. Kira." A cold, calculative voice said. I turned around, trying to find the source of the voice. I knew that voice, it was oh so distinct. That, was the voice of Benedict Cumberbatch. Well, I suppose in this universe it's the voice of the great Consulting Detective Sherlock Holmes. Sherlock walked into my field of vision.

"Yes well, I suppose you won't know what the Time Vortex is will you. Though I'm not sure how I'd go about explaining it. I suppose I could just say that it's a vortex where all of time and space meet, a place where, if one could travel through it, they'd have all of time and space as a destination. I suppose that's the best way of explaining it. Though, I can also say that there is more than one Time Vortex. At least, in theory there should be. There should be a Time Vortex for each and every separate universe in existence, and I suppose, for me to be here, those different Time Vortex's must converge and meet at certain points." I tried to explain. Sherlock seemed to understand what I was trying to say, if the look of concentration was anything to go by.

"Hm, interesting theory, but you have no way of proving it. So that is what it shall stay. A theory." Sherlock said, turning to walk away. But I couldn't let him do that. I wasn't quite sure why, but I needed him to understand and believe me. Maybe it had something to do with the fact that he was the best chance I had at finding a way to get back to the Doctor.

"I can prove it if you'd like. I can't show you the Vortex, at least, not yet. But I can prove that I have future knowledge that no one should have unless they've witnessed your future." I said slowly, watching Sherlock's reaction. He seemed intrigued, but far from convinced. I knew it was dangerous, telling someone their future. I had to choose what I said carefully, make sure that it was something that wouldn't change the future to much. "Where are you? I mean, what was the last case you solved and how long ago was it?" I asked both Sherlock and John.

"Our last case? Don't you mean our first case?" John asked, obviously still confused. That little piece of information caused my eyes to widen in surprise. It was that early in their timeline?

"So that means that you've only gotten as far as 'A Study in Pink? That's just... so early in your timeline. Hm, then, if my memory's correct, your next big case will be-" Everything went golden as I fell back onto the couch, my body convulsing as I struggled to breath. Everything burned again, and I feared that I'd leave again, that I'd open my eyes and find myself in some other, new and far away place. The burning lasted for what felt like years but in truth, was only a few seconds.

I opened my eyes, unsure of when I closed them and looked around. I was still in 221b, with a concerned John and curious Sherlock standing over me. I moved my hand into my field of vision and was slightly relieved as well as disappointed to find that it was still the hand of a 5 year old.

"Well, that wasn't fun at all." I groaned, moving to sit up and run my hand through my hair. It was then that I noticed how long it really was and I grimaced. I hated having long hair. It's not that I had anything against long hair, It's just too hard to take care of. I turned towards John and Sherlock, surprised to see that they were still watching me with the same concerned and curious expressions as before. "What? What's wrong?" I asked, my tone becoming nervous. I just I wasn't quite sure why, part of me thought that I wasn't done changing. Or, as the Doctor would say, I was still cooking. And I was scared about what that change would turn out to be.

"Um. Y-Your eyes." John stuttered. I looked from John to Sherlock, waiting to see if either of them would explain what was so odd. After a moment of silence I stood up and ran to where I assumed the restroom would be, luckily I was right. I rushed into the room and stared at my reflection in a mixture of shock and aww. My eyes were, instead of there normal dark brown, a mesmerizing mix of gold, silver, blue, and purple. They looked, in all honesty, like the Time Vortex.

Sherlock Holmes POV
~8~

The girl was interesting, without a doubt, but she was an anomaly. Not only the way she appeared, or her odd changes in physical appearances, but her mannerisms as well. She acted and held herself like a young adult. I was, regrettably, surprised to see her appear in a flash of golden light. Though there are many ways to explain her sudden appearance with science and deduction, none of them fit quite right. There was always a blank space, an area left to chance.

That was unacceptable. Now there was the odd seizure the child had that had further changed her physical appearance. She was, without a doubt, an anomaly I wished to get to the bottom of. A puzzle that I couldn't wait to solve. This child, no, this anomaly will not stay a mystery long. I will solve this puzzle soon.
