Change isn't easy, but in "Doctor Who," we often have companions who help us transition to a new Doctor. The arrival of the 12th Doctor (Peter Capaldi) meant that Clara Oswald (Jenna Coleman) had to serve as the audience surrogate and help the transition from bow ties & fezzes to a no hugging magician. Clara's relationship with 12 is different from her interactions with 11, and after she left, audiences got to meet Nardole (Matt Lucas) and Bill Potts (Pearl Mackie). Jessica and Phillip talk about the unique aspects of these companions to the 12th Doctor, and how they relate to companions both past and future.
In their look into the TARDIS library, the couple visit the inaugural 2nd Doctor serial "The Power of the Daleks," as Ben and Polly must cope with the first regeneration of the Doctor. How do these companions help the audience with this first change in the Doctor?
