Rose and The Doctor in “Army of Ghosts”

(voice-over) Planet Earth. This is where I was born. And this is where I died. The first nineteen years of my life, nothing happened. Nothing at all, not ever. And then I met a man called the Doctor. A man who could change his face. And he took me away from home in his magical machine. He showed me the whole of time and space. I thought it would never end.

[with Rose on an alien planet] How long are you going to stay with me?

Forever.

(voice-over) Well, that's what I thought. But then came the Army of Ghosts. Then came Torchwood and the war. That's when it all ended. This is the story of how I died.
