Mr. Anonymous. There were times he wished that was his name. Hidden in the shadows. Not seeked after, no need to save the world, again and again and again. He wished he could be like other Time Lords at times and observe the true principles of Galifrey. The point remained walking into a room announcing you are The Doctor people flock to you, assume you are some sort of savior. Like it or not. With a name such as Anonymous people in that room would assume just as easily you were that, and quickly turn away.
It was in his companions' eyes that he would rekindle the love of the worlds, his self declared duty and proudly called himself Doctor.
