DOCTOR: In all my travellings throughout the universe I have battled against evil, against power-mad conspirators. I should have stayed here. The oldest civilisation, decadent, degenerate and rotten to the core. Ha! Power-mad conspirators, Daleks, Sontarans, Cybermen, they're still in the nursery compared to us. Ten million years of absolute power, that's what it takes to be really corrupt.

The Sound Creature: I shall go and find Papa. I know he'll let me live

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.

THE DOCTOR: We must fill these seconds quickly. We'll never get another chance. All the waste. These seconds are gone forever. What's the point of filling them? Everything temporary. Only memories left until the memories fade. How can you live like this? How can it not drive you mad?

SKY: He's waited so long.

DOCTOR: He's waited so long.

SKY: In the dark.

DOCTOR: In the dark.

SKY: And the cold.

DOCTOR: And the cold.

SKY: And the diamonds.

DOCTOR: And the diamonds.

SKY: Until you came.

DOCTOR: Until you came.

SKY: Bodies so hot.

DOCTOR: Bodies so hot.

SKY: With blood.

DOCTOR: With blood.

SKY: And pain.

DOCTOR: And pain.

IANTO: I love you.

JACK: Don't. Ianto? Ianto. Ianto, stay with me. Ianto, stay with me, please. Stay with me. Stay with me, please.

IANTO: Hey. It was good, yeah?

JACK: Yeah.

IANTO: Don't forget me.

JACK: Never could.

IANTO: A thousand year's time you won't remember me.

JACK: Yes, I will. I promise. I will. Ianto. Ianto? Don't go. Don't leave me, please. Please don't.

DOCTOR: Tegan, sometimes I wonder how well I'd get on without you

TEGAN: Thank You

DOCTOR: Probably quite alright, all things considered
