Russell T Davies' latest era of Doctor Who is dripping in mystery and intrigue, with season 15 revolving around the mystery of Belinda Chandra. Doctor Who is a show that has always clung close to mystery, whether it be the secrets of the Doctor's real name, the Time Lord race, or simply unsolved mysteries from the past. However, in the latest season of the series, Doctor Who is leaning heavily into the idea that Belinda Chandra is someone important, and integrally tied to the Doctor in ways the show has yet to reveal.
