We haven't seen much of Jodie Whittaker's take on the Doctor yet -- just her regeneration, at the end of Peter Capaldi's run, as the thirteenth Doctor and a few brief promo shots. Now, at San Diego Comic-Con 2018, we got our first glimpse of the new Doctor's personality. She says everything is new: New worlds. New times. New faces. In light of all that, the new Doctor asks a single question: "Will you be my new best friends?"

Presumably, that question is for Whittaker's co-stars, Bradley Walsh, Mandip Gill and Tosin Cole -- who are set to play Graham, Yaz and Ryan, the Doctor's new companions.
