The worst part of it all was that everything I had said to her, to Amelia Pond, had been true. I had taken her, and everyone else, out of vain. I had failed her time and time again, and she had shown nothing but faith. And that faith had done nothing but caused her pain. Yet she said not one harsh word towards me, and the pain in her eyes was apparent as I left her side. I could hear the last whistle of the Tardis as it faded away. A lone tear was going down my face, and I let out a low sigh. The girl who waited… Amelia Pond. Memories of countless other companions were flooding my mind, and it was seemingly too much to bear. How was it that these people could want to stay by my side? And how was I vain enough to let them? I knew that if I had just.. Left her… and never had returned, never put her in danger, this wouldn't have happened. She wouldn't have died. She wouldn't have been left behind. She chose her fate, like everyone does. Everything that has ever happened and ever will happened is a conscious effect of someone's choice. This world, this god-awful, terrible, beautiful… world, has been shaped by the choices, both good and bad, of these people. These blind, oh so blind, people. Amelia was gone. I had watched the weeping angel take her, but had known beforehand there was no other option. For where Rory went, she would surely seemed almost unfair, that they should have each other, even in that darkness, but I am to be alone always in the end.
I was alone yet again, something I would have thought I'd be used to by now. It struck me yet again that the girl who had taken a fancy to me, was in fact, Amelia and Rory's daughter. It seemed oddly… fitting. This timeline stuff was beginning to wear on me, a very recent development.
I had revealed so much of my inner self to her, and yet she still never left my side. And here I was, leaving her again. I wanted to think that she was at her house, and that I could see her again. That she would still be the girl who waited for me all those years ago. That she would still consider me her "raggedy doctor".
I couldn't bear to sift through these thoughts and emotions, but knew try as I might, there was no way to push them away. So many companions throughout the years, all lost in time. I wondered if I, The Doctor, even served a purpose. I had surely destroyed just as many lives as I had saved. And at that, I let all my feelings go. It was time to let the past be just that. The past. Goodbye Amelia, The girl who waited. Goodbye Rory, the last Centurian.
