CHARLEY: Thank you, Doctor. Thank you for that strength. But I have my own strength too, and I refuse.

THE SOUND CREATURE: What?

DOCTOR: You refuse, Charley? You'd do that for me?

CHARLEY: I do not accept your sacrifice. Not this time

THE SOUND CREATURE: No! You can't!

CHARLEY: Let her burn in the R101. Let her be executed by the Time Lords. Live on. With regret, but live on.

THE SOUND CREATURE: No!

CHARLEY: Right or wrong, whatever happens to Charley Pollard, I choose the Doctor to live.
