Is Doctor Fifteen a new person?

Doctor Fifteen is a new character played by Ncuti Gatwa. This character was created through a novel concept known as bi-generation, in which the Doctor separated from the Fourteenth Doctor's body, allowing both incarnations to co-exist.

Nicola Coughlan, Ncuti Gatwa's co-star, stated on The One Show,

"But [Ncuti Gatwa] is incredible in the role... It was very fun. I think it was meant to be a secret that it was Christmas, but then Russell told everyone."

Showrunner Russell T. Davies told Radio Times,

"At last, it's my great delight to unleash a whole new season of the Doctor and Ruby's adventures together."

Does Doctor Fifteen have all his memories?

Doctor Fifteen in Doctor Who retains memories despite his separation from the Fourteenth Doctor. This unique regeneration process enables both incarnations to retain memories, with the Fourteenth Doctor still eager for adventures.

At the same time, the Fifteenth Doctor ushers in a new era, centered on new companions such as Ruby Sunday. This intriguing concept of bi-generation introduces a dynamic in which both Doctors coexist with their memories intact, influencing their paths and interactions throughout the series.

However, David Tennant and Ncuti Gatwa's Doctors shared the Fourteenth Doctor's costume. So, there might be a possibility that not all memories were transferred.
