The resemblance between season ones sixth episode, Dalek, and season eights second episode, Into The Dalek, are too many to be ignored. Specifically, the line where the transformed Dalek in both episodes tells the Doctor that he is a good Dalek, based on his hatred for the species thats dogged him for centuries, murdered whole civilizations and ruined his life. Now, transpose that to the repeated questioning in the early part of this season as to whether the Doctor is a good man, and the concern over whether Twelve actually fits that description and weve got ourselves a narrative through-line. We dont think the Daleks are due to reappear in this season, but this repetition from older storylines is starting to become a real thing in season eight. Is this Doctor a good man?
