The Doctor was still glaring at Ashildr. He couldn't know how filled with remorse she was. She'd genuinely liked and cared for Clara Oswald and now she was the instrument of her death. Responsible for whatever became of The Doctor after this. She feared he would be darker now, more dangerous and less caring. He really did try to be a good man and make the right choices. She needed to say something to apologize, but there was nothing to say except one piece of knowledge.

"If it helps, Doctor, her fate was meant to be my own." She said into the silence. "It was meant for me."

There was nothing to say to her confession, and there was the flash of light and The Doctor was gone.
