Bill Confronts Another TARDIS In Doctor Who Christmas Special Clip

 
Traveling in time and space can leave one very confused. As an example, here’s a clip from next week’s Doctor Who Christmas special, “Twice Upon a Time,” in which Bill (Pearl Mackie) must confront the reality of stepping into the Doctor’s TARDIS thousands of years earlier in its own timeline. Its operator: The First Doctor (David Bradley).

She also notes one of the production’s running gags: the size of the police box windows, which varies every time the prop is rebuilt. Oh, but once inside, she and the Twelfth Doctor (Peter Capaldi) are treated to a loving recreation of the original TARDIS console room.
I wonder if she’s come to grips with the two Doctors by this point in the story?
The Doctors and Bill returns for “Twice Upon a Time” on December 25th.
