The goodbyes begin now, apparently.
Doctor Who hit up Hall H for both the last day of San Diego Comic-Con and its last panel featuring Peter Capaldi and showrunner Steven Moffatt, and gave us a sneak peek at this year's Christmas Special.
The special, called "Twice Upon a Time," will be Capaldi's final appearance as the Doctor, Moffatt's last episode as showrunner, and Pearl Mackie's last appearance as companion Bill Potts. It will also feature David Bradley as the first Doctor, who was originally played by William Hartnell, and writer/occasional Doctor Who guest star Mark Gatiss as "The Captain."
Apparently, something has gone very wrong with time, trapping everyone inside a single moment, and it's up to the two doctors to fix it.
The panel itself was largely a goodbye to Capaldi, Moffatt, and Mackie, featuring standing ovations for Capaldi and a chorus of boos when it was announced that the Christmas special would also be the last time we'll see Bill.
After the Christmas special, Chris Chibnall will be taking over the job of showrunner, while Broadchurch star Jodie Whittaker will be taking on the role of the Doctor. It will be the first time in the 54 year history of the series that a woman will play the famous savior of the universe.
Whittaker will likely appear in the Christmas special and then officially take over in 2018.
Doctor Who will return to BBC America this Christmas.
