A.N. This is a series of short fics about the Tenth Doctor, from the POV of his companion. This companion isn't Rose or Martha, sorry. Just someone of my own invention to look through the eyes of. I don't know how long or short this will be, I'll update when the muses move me. Please don't hesitate to give constructive criticism if you think there's something I should be doing better, I'm always looking to improve.

Part One:

I travel with him. I don't know why he chose me, but I'm grateful. With him, I've seen a sun breathe it's last, a mountain speak. I've seen a living rock bleed dry, giving it's life-force to save a civilization. By his side, I've faced things that defy description, and I've helped to save my species. But the greatest wonder of all remains beyond my understanding. Him.

Who is this mysterious him, you may ask? Well, the easy answer is this; He's the Doctor. That's the name he chose. "Just-The Doctor," He is fond of saying, tossing off a nonchalant smile before turning, coattails flapping, to save the world again.

No matter how much he is pressed, that's all he'll really say. The Doctor. Somehow, this simple title fits him like a glove.

He has the power of life or death over us all, but we don't know it. The Doctor doesn't look for recognition and medals, he just does what has to be done. He is precise, meticulous, and ever wary. He has to be. If he isn't, if he slips up, miscalculates even a bit, death is the result. True, his methods seem off-hand, even dangerously casual, but it comes from the familiarity of long practice.

His knowledge is great, but considering he has lived over nine hundred years, it isn't surprising he knows so much. What is endlessly surprising is that he cares about the human race, despite our many flaws.

A doctor is a healer. The Doctor makes people better, though not in the everyday sense. The people he meets are forever changed. 'The act of observing changes the observed' is a true statement. Even those to whom he makes it clear he holds in contempt are changed, fearful of what he sees in them.

And for those rare few he inexplicably deems worthy to travel with him in his TARDIS? We become different people, old lives burned away. He shows us a new way of living, one based off bravery, tenacity, quick thinking, and just a dash of simple luck.

The traveler takes us along for the ride to fend off loneliness, to share the wonder and horror with someone else. Yet he keeps a certain distance, knowing that eventually, we will leave him. This distance makes it hard to know him. I have come to accept it. I think the Doctor is grateful I don't try to press the boundaries between us, and somehow both of us knowing the limits of our relationship lets us become very close. He tells me about his life sometimes, about Gallifrey and the Time War. I listen as he shows me marvels, and I count myself lucky.

But the most important thing the Doctor shows us is that one simple person, at the right place and time, truly can change the world. All you have to do is believe, and try.

A.N.2 Also, I'm happy to take requests! If there's an aspect of the Doctor's character you'd like me to explore, don't hesitate to mention it, and I'll see what I can do for you!
