Flux: Chapter One - The Halloween Apocalypse - S13-E1
Continuity mistake: At the very start, when Yaz says, "Oh yeah, we are totally in command," just as it begins to zoom out, the handcuff around Yaz's right wrist has the double bar facing out and her left wrist has the single bar facing out, but in following shots both handcuffs are facing the same way. Similarly, this occurs with the Doctor's handcuffs around both wrists, when the Doctor keeps trying the voice recognition. (00:00:10)
Flux: Chapter One - The Halloween Apocalypse - S13-E1
Continuity mistake: Karvanista smashes his way into Dan's house by breaking down his door with an axe. When the Doctor and Yaz arrive after Dan's abduction, the hole in the damaged door is smaller than it was originally. (00:17:30)
Flux: Chapter Three - Once, Upon Time - S13-E3
Continuity mistake: In the previous episode Swarm put markings on Yaz and Vinder to mark them as replacement Mouri but in this episode, which takes place right after, they no longer have any markings.
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 after everything the Master's put him through hurts him more deeply than death would.
