Doctor Who is coming back October 7th with the very first female Doctor. And she will be the 13th Doctor, depending on how you do the math. There have been Movie Doctors, an American Doctor, and differing Doctor variations on the actual show, but they don’t count. In one episode, David Tennant’s Doctor split into two Doctors, permanently, but he still only counts as one Doctor. I know it’s confusing, but chaos is the show’s middle name. So! Officially, according to canon, there have only been twelve Doctors. With the new female Doctor becoming number 13! But is the number 13 lucky, or unlucky? Tune in October 7th to find out.
