While 'Twice Upon a Time' leans on nostalgia and wraps up Peter Capaldi’s run, the narrative largely respects established character arcs. There’s a hint of forced emphasis when the First Doctor is played for outdated jokes, but identity isn’t the story’s main focus. Most cast choices seem consistent with story history rather than contemporary ideological motives.

The First Doctor’s old-fashioned views are played up for comic effect, and there are a few moments gently mocking traditional gender roles. However, the episode overall doesn’t aggressively undermine religion, family, or tradition outside these lighthearted jabs, making it relatively balanced for modern Doctor Who.

Although it pokes fun at some traditional perspectives, the episode offers affectionate nods to the past and doesn't completely villainize alternative views. The regeneration into a female Doctor is teased at the end, highlighting the show’s direction, but pluralism isn’t totally absent.
