Even though they had just finished filming the Christmas special "Twice Upon a Time," Doctor Who brought a small glimpse of it to Comic-Con -- along with the news that Pearl Mackie would return as Bill, and Mark Gatiss would be appearing in it.

Steven Moffat, in what will be his last Doctor Who Comic-Con as a the showrunner, said that the episode is about the Doctor refusing to regenerate and going on an adventure with Mark Gatiss.

All of this was a goodbye to Moffat and Peter Capaldi, also in his last Hall H appearance as the current doctor, and even Mackie, who confirmed that this will be Bill's last outing.
