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 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 Craham, Yasmin and Ryan, the Doctor's new companions.
