Halfway through the show, and we still don’t know who the new Doctor is. If you’ve just tuned in, well, then quite a large part of me envies you.
Zoe is talking to Peter Davison (who was the Doctor once), the little boy from Outnumbered (because he went to visit a doctor once) and Liza Tarbuck (because her name has the letter C in it, and so does the word ‘doctor’).
Edit:
Now Zoe Ball is explaining that the Doctor has the ability to regenerate, which apparently means that he changes in appearance. I don’t know about anyone else, but I had no idea about this. I hope she explains what that funny blue box that he flies around is next, or what Doctor Who is. Or what a television is.
