The Doctor, the Widow and the Wardrobe - S7-E1

The Doctor, the Widow and the Wardrobe - S7-E1
Factual error: Cyril is introduced looking at the Moon with a telescope... in a brightly-lit room through a window with the curtains mostly shut, circumstances in which he's not going to see anything at all. (00:03:56)
The Doctor, the Widow and the Wardrobe - S7-E1
Revealing mistake: When Cyril is walking around the statue and chair in the tower, if you look closely you can see the statue's hands move or shake. (00:30:14)
The Doctor, the Widow and the Wardrobe - S7-E1
Continuity mistake: When the Doctor asks the wooden people to show the Arwells where the timeship is going, the queen raises her hand, widening the window's field of view. In a shot shortly after focusing on the Doctor, the queen's hand is lowered in the background, before suddenly being raised again. (00:48:57)
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.
