Doctor Who Showrunner RTD Details Why A Former Doctor Cameoed In Season 15, Episode 5

As Doctor Who season 15, episode 5 "The Story & the Engine" featured a surprise cameo from a past Doctor, showrunner Russell T Davies explains why the episode was the right point to bring the star back and address their incarnation's story. The latest season of the long-running sci-fi series sees Ncuti Gatwa's Fifteenth Doctor and new companion Belinda Chandra (Varada Sethu) attempting to return to present-day Earth. In Doctor Who season 15's "The Story & The Engine", a visit to an old friend in 2019 Lagos draws the Doctor into a plot to exact vengeance on the Gods themselves.
