The Doctor: The day the Earth was stolen and moved across the Universe. And you…
Brooke: I saw the Daleks. We looked up, the sky had changed. Everyone was running and screaming. And my father took hold of me. I never saw him again. Nor my mother. They were never found. But out on the streets there was panic. And burning. I went to the window. And there, in the sky, I saw it, Doctor. And it saw me. It stared at me. It looked right into me. And then… it simply went away. I knew that night, I knew I would follow it.
The Doctor: But not for revenge.
Brooke: What would be the point of that?
