"Clara," he murmured, gently working his fingers into her hair. "You've always been here for me, always trying to help me. I was blind to you before. But I see you now," his voice broke, "Clara, my Impossible Girl- I see you, and you are beautiful."
She looked up at him, wide dark eyes filling with tears, lips slightly parted. "Doctor," Clara whispered voice raw and cracked. He leaned down into her, and their mouths slid together. It tasted of tears, and regret, and of sadness and longing. It was perfect, and it was all she ever wanted.
But now it was going, fading as the golden light enveloped his face, and thus hers. She would fight the inevitable- she kissed him harder, ignoring the crumbling of the world. Everything was fire, yet they burned brighter. And then- suddenly, abruptly- it ended. In her arms, he changed.
She broke away from him, this new Doctor, gasping and sobbing.
The Doctor was born again from the flames, and she was left with the ashes.
