10 Quintessential Doctor Who Moments From The 12th Doctor
3. Bill!
Replacing Clara—who’d been by The Doctor’s side since he was portrayed by Matt Smith—wasn’t an easy job. The show needed an amazing character, who’d likely only be around for one season, yet her chemistry with Capaldi had to be strong enough to make his final season a memorable one. Lo and behold they found just that in Pearl Mackie’s portrayal of Bill Potts.
Their chemistry isn’t just good, it’s gold. The fans love their rapport so much that Bill’s arrival in 2017 has been deemed a revitalization of an age-old formula. It’s unclear whether or not Bill will return for series 11—so far, most indications are that she will not—but if the fans had their way, she’d be allowed to stay as long as she wishes.
