From the beginning, she was Impossible, the Impossible Girl. I met her in the Dalek Asylum, never saw her face, and she died. I met her again in Victorian London, and she died. Saved my life both times by giving her own. But now she's back, and we're running together, and she's perfect, perfect in every way for me, except she can't remember that we ever met. Clara, my Clara, always brave, always funny, always exactly what I need. Perfect. Too perfect. You get used to not knowing. Thought I never would. I was wrong. I know who Clara Oswald is. I know how she came to be in my life, and I know what she will always mean. I found out the day we went to Trenzalore.
