After two years of waiting, Sacha Dhawan’s incarnation of the Master makes his return to the Whoniverse in a newDoctor Whoaudio adventure. The actor made a surprise debut in 2020’s season 12 premiere “Spyfall”, where it was revealed that the Thirteenth Doctor’s (Jodie Whittaker) MI5 contact 0 was the rogue Time Lord, vengeful and angered after his world was shattered by recently uncovered Time Lord history. Burning Gallifrey down and wiping out the species once more, Dhawan’s incarnation of the Master tried to invade Earth with interdimensional foes, created Time Lord/Cyberman hybrids, and stole the Doctor’s body.
Big Finishhas unveiled that the Master will return inCall Me Master: Inner Demonsin February 2025. The three-story box set findsDhawan’s Master is in the midst of an identity crisis at an unknown point in his life, as Robert Valentine’s “Self-Help” sees him dealing with his existential woes, Georgia Cook’s “The Clockwork Swan” sees him become an unlikely detective to solve murders at a futuristic theme-park, while Una McCormack' “The Good Life” leaves him on a reclusive island among a religious order. The first box set will be released on the Big Finish website for £18.99,with a second currently untitled box set slated for September 2025.

What Call Me Master Could Mean For The Character
The Master’s Timeline Is Still A Mystery
Though Dhawan’s Master followedMichelle Gomez’s take on the character, there is still no solid connection between the two on-screen, asDoctor Whoseason 10’s finale “The Doctor Falls” seesMissy’s prior incarnation (John Simm) blast her with a laser shot strong enough to make a regeneration impossible. Big Finish themselves would explore the regeneration with the introduction of the Master’s following good incarnation, The Lumiat (Gina McKee), though Missy would ensure that her future self regenerates back into their worst self.
