The Magician's Apprentice - S9-E2
Continuity mistake: During the exchange where the Doctor says "You flatter me" and Davros responds "A pity. I intended to accuse", Davros' hand goes from just under his chin to resting on his chair's control panel. (00:40:15)
The Magician's Apprentice - S9-E2
Continuity mistake: When Colony Sarff arrives at the arena, he's seen unclasping his hands twice, in the close-up and following wide shot. (00:28:38)
Chosen answer: The Master knows that deep down, he deserves death for the crimes that he's committed throughout his life, and since he regards The Doctor as his arch-foe, he expects it to be at his hands. The fact that The Doctor is still willing to forgive him for all of his crimes hurts him more deeply than death would.
