The BBC has officially confirmed who will be the new companion for Doctor Who’s upcoming 15th Doctor, set to be played by Ncuti Gatwa, revealing that Millie Gibson will join him on the TARDIS in 2023. Best known for appearing in the hit UK series Coronation Street, Gibson will take on the role of Ruby Sunday in the series. It’s unclear exactly when Ncuti Gatwa and Millie Gibson will make their official debut as their characters, especially since the recent special episode of the show had Jodie Whittaker’s Doctor surprise regenerate into none other than David Tennant, a plot thread that will be explored across three more specials before the pair begin their new run on the character.
