Former Doctor Who showrunner and returning writer Steven Moffat promises an emotional seasonal tale for Bridgerton star Nicola Coughlan’s 2024 seasonal special character. Following his eight-episode debut season, Ncuti Gatwa’s Doctor had a heartbreaking farewell with Millie Gibson’s companion Ruby Sunday, as their lives began to take them in different directions. While Gatwa and Gibson will reunite in Doctor Who season 15 when the series returns in 2025, Coughlan is expected to portray a one-off companion character in the seasonal episode, penned by Moffat, set to air in December of this year.
