Donna.
It was a strange sensation, the abrupt removal of information from the brain. She could feel the Doctor's fingertips at her temple, her cheekbones, her jaw. She could see his anguished thoughts, his pain at removing/eliminating/deleting her-his best friend. His tired, age-old eyes that reflected lifetimes long past and a vague wariness to the future flickered-his attempt at holding back the tears.
She was one more of his kind that he had to get rid of, to kill. First the planet, then the Master, and now her. The last other Gallifreyan on this side of the skin of reality. Once again, he would be handed the title of the Last Gallifreyan, the Last Timelord.
With her last Gallifreyan strength, she pushed one final thought towards him, praying that he would still receive it.
Remember.
