When Good Omens wrapped its first season, the story was over. That was it, the Amazon Prime TV series created by Neil Gaiman had finished adapting Gaiman and Terry Pratchett’s 1990 apocalyptic comedy novel. But Gaiman wasn’t quite finished with the tale of the angel Aziraphale (Michael Sheen) and the demon Crowley (David Tennant).

“We always knew from the beginning that there was more story because Neil and Terry, when Terry was alive, had talked about ideas beyond the first book,” Sheen tells Inverse.

Nearly five years after they filmed Season 1, Sheen and Tennant settled back into their characters as if they’d been doing this for, well, millennia. In an interview with Inverse, the two stars discuss Good Omens Season 2, how they dealt with the show’s passionate following, and what Easter eggs fans can expect to see.

David Tennant is making history with his return to Doctor Who. He’s the first actor in the show’s 60-year run to reprise the role of the Doctor after parting ways with it, and he’s the first to play a completely different incarnation.

Yes, Tennant’s 14th Doctor will be a different person than the 10th Doctor, who he played for nearly five years starting in 2005. Tennant’s new Doctor might share the same face (and penchant for saying “What?!”) as the 10th Doctor, but he carries all the key memories and personalities of the past three doctors. Which must mean Tennant went back to watch the seasons of Doctor Who led by Matt Smith, Peter Capaldi, and Jodie Whittaker, right? Not quite.
