Dalek: I scanned your satellites and radio telescopes.
Doctor: And?
Dalek: Nothing. Where shall I get my orders now?
Doctor: You're just a soldier without commands.
Dalek: Then I shall follow the Primary Order. The Dalek instinct to destroy. To conquer!
Doctor: What for? What's the point? Don't you see? It's all gone. Everything you were, everything you stood for.
Dalek: Then what should I do?
Doctor: All right, then. If you want orders, follow this one. Kill yourself.
Dalek: The Daleks must survive!
Doctor: The Daleks have failed! Why don't you finish the job and make the Daleks extinct? Rid the universe of your filth! Why don't you just die?
Dalek: You would make a good Dalek.
