The Pyramid at the End of the World - S10-E8
Continuity mistake: When Erica's eyeglasses get smashed, they're seen in a closeup inside her bag and the lens frame is cracked, but when she takes it out of her bag both lens frames are intact around the broken lenses. Also, when Erica takes the eyeglasses out of her bag she holds the eyeglasses' right temple in the closeup, but in the next shot it's the left temple being held up. (00:06:15)
The Pyramid at the End of the World - S10-E8
Continuity mistake: When the Doctor, Bill, Nardole, et al. first see the pyramid their long shadows are cast directly in front of them, but when the Doctor decides to "bring it" and crosses the barrier, their long shadows are cast directly to their right. Then it keeps changing in the following shots when the Doctor approaches the pyramid. (00:10:45)
The Pyramid at the End of the World - S10-E8
Continuity mistake: While the Doctor, et al. Are in the pyramid with the Monks, when the Monk tells the Secretary General that if his consent isn't pure it will kill him, Xiaolian is standing right behind him in shots facing the Secretary General and shots facing the Monk, but in the one shot of the Secretary General as he's being vaporized Xiaolian has vanished, but Xiaolian is still standing in the same spot in the shot facing the Monk.

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.
