Doctor Who is ready for his 14th regeneration (*). After 3 years with the sharp and aged face of Peter Capaldi, the Doctor will be played by an new actor that is, for the first time in 54 years, a woman: the british actress Jodie Whittaker.

Peter Capaldi too, as the Doctor, had to handle hard and complicated situations, as in the Gallifrey cospiracy against him, and in every story involving the new The Master's incarnation, Missy.
What awaits the 13th Doctor and her companion, Bill? About Bill, we know she is a funny character (and so is the last co-companion, Nardole), so this will be a trait to consider in shaping the next Doctor. I mean, I think Jod...
