Ace : You like it, don't you, Professor? All the lying and cheating and treachery. You even enjoy it.

(The Doctor smiled wryly. )

The Doctor :Perhaps I do, in a way. You have to remember, I grew up in a society so complex, devious and corrupt it makes this lot look like a kindergarten?

Ace: What, you? A Time Lord? I should have thought it was all sweetness and light and high tea in the nursery?

(The Doctor shook his head. )

The Doctor :When it comes to low cunning and high treason, the Nazis have got nothing on the Time Lords of Gallifrey.
