Speaking in an interview with the latest issue of Doctor Who Magazine, Tennant said that the first episode, titled The Hidden, is "quite high-concept", calling it "a clever bit of writing".

Speaking about the new audio adventures when they were first announced, producer and script editor Matt Fitton said in a statement: "The Tenth Doctor and Rani Chandra feels like a TARDIS team that was always meant to happen! United by their love for Sarah Jane Smith, it's only fitting that Rani gets to follow in the footsteps of her mentor and venture out into time and space.

"She runs into the Doctor in Cumbria as she investigates sightings of strange creatures for a potential podcast – I wonder what happens with that? – and is soon whisked away to amazing adventures.

"Like Sarah, the Doctor sees Rani’s potential immediately – the pair soon run into his wife-to-be Princess Elizabeth, and a very familiar 1970s TV sci-fi show."
