Millie Gibson’s Ruby Sunday was greatly teased to be special in Doctor Who season 14, and even though the mystery behind the first companion of Ncuti Gatwa’s Fifteenth Doctor has already been seemingly solved, I’m convinced the upcoming run will bring an unexpected reveal about Ruby. Even though Gibson left as a member of the main cast at the end of Doctor Who season 14, the trailers for the next batch of episodes confirm that Ruby is returning to be part of Doctor Who season 15’s story. Hopefully, showrunner Russell T. Davies has something mindblowing in store for her.
