Pearl Mackie has admitted she doesn't know if she will stay on Doctor Who past season 10. The actress made her debut opposite Peter Capaldi's Doctor at the start of the current season, which will also be Capaldi, and showrunner Steven Moffat's, last. As Bill Potts, Mackie has made an immediate, and very positive, impression on viewers. Her chemistry with Capaldi is a true joy to watch, and coupled with much stronger writing, which is far more focused on character and a more traditional approach to Doctor Who, the teaming of Capaldi and Mackie has proven to be a stroke of genius.
Sadly, though, it's not to last. Capaldi's Doctor will regenerate during the 2017 Christmas special, or possibly much sooner if the series hints are to be taken seriously. His departure brings with it persistent rumors that Mackie is also set to leave the show. Speaking on This Morning in the U.K., the actress didn't confirm that she was departing Doctor Who, but said she didn't know. She also added that it's not up to her, obviously, but she did add that she thinks the dynamic that the two share in the TARDIS, works:
"I don't know. Well, it's not up to me, I don't think, but I feel like Peter is such a wonderful Doctor. I think the dynamic he and I have playing The Doctor and Bill really works, [but] that's not to say it wouldn't work with a new Doctor. I think it's always a new adjustment getting a new Doctor and that dynamic is different because you're different actors and characters."
Before Bill's arrival, the twelfth Doctor wasn't given the chance to have a new companion when he regenerated; he inherited Clara, who already knew so much about his work and the whole idea of space and time-travel. This resulted in a much more even balance between the pair - but while Clara was a great character, the naivety of Bill and the sheer awe she experiences week on week, has given Capaldi a new dynamic to work with, and injected the show with an energy that it has been lacking for a long time.
Undoubtedly, if Mackie does leave, fans will be very sorry to see her go, but the question is raised of whether she would or could share the same energy with a new Doctor? Incoming showrunner, Chris Chibnall is said to be starting Doctor Who season 11 with an entirely clean slate; new, (casting as yet unknown) Doctor, new companion... even Michelle Gomez's Missy is bowing out. Sadly, Mackie's leaving would seem like a logical choice for a showrunner wanting to make their own mark on such a popular show.
Doctor Who Season 10 continues on BBC 1 and BBC America with 'Extremis' this Saturday, May 20th.
