A lonesome seemingly young man walks the dark deserted streets of some city, in some world, in some time period. As he wanders where ever his feet will take him he trusts that they won't get him into too much trouble this time; he stares off into some other place. His ancient mind never at ease with what he has become, and what he is most likely destined to do.
He sees the past, the present, and the future all at once, constantly. And he's entangled in it all; he is responsible for the balance of existence. Yet, in some ways he has no say in things at all, he can't change what is fixed in time. Sometimes this drives him mad especially those days he wants nothing but to go back and change at the risk of everything, every universe, every living being. Faces of familiar old friends flash in his mind, glimpses of entire races dance across his memories, moments of evoking fear in the very souls of beings so terrible that a word usually meant for healing means a fierce warrior in some languages, he wonders if that was even his goal in the first place. Sometimes he just feels so alone and so very old. Suddenly he sighs and gradually his shoulders slump in a slight despair. So many beings depending on him. He loses his ability to concentrate and searches for his escape of the world.
In the distance there's a blue police call box sitting there as if it's waiting for him to return. Just like every other time; the 'sexy' companion that never leaves him. He spots the box and begins to trot quicker towards it as if trying to escape his thoughts, maybe even his own self. Two hearts beating with the familiar adrenaline of the upcoming adventure and the lust for something new and exciting. Where will he go next? Who will he meet? What exactly is he going to get himself into this time? And then his guilt comes back, usually when he begins to travel he wonders what lives he's going to change for better or worse that day. The past is always nagging at him. 'Maybe it'll be better this time.' He muses each and every time. It never is. One moment things could be going well and the next he blinks and all that is gone. As if that one peaceful moment never happened.
As he reaches the box he slowly opens the doors as if dreading it, yet carefully as if he still has hope for the best. And that's all he needs to get through this lonesome journey just a little bit of hope that maybe one day he won't be so lonely. That this traveling man in the blue box will find what exactly his hearts were looking for when he started this journey. What that was? He's not quite sure. But he'll know when he knows, he tends to have a good sense about things like that.
Who is he exactly?
The Doctor.
