You mentioned that you wrote Aziraphale and Crowley as a love story in the TV series. Why did you decide to make this change from the books? I find this a very interesting distinction!

Mostly because the show needed focus, and because it solved the narrative problems of neither of them being in episode 3. That way the bandstand scene came as the culmination of the first half hour of episode 3, and tipped us into episode 4. And once I’d done that, it had its own rhythms. (I’m sure there is a way of talking about writing that’s more exciting than this, which sounds like everything is a half-unconscious set of problem-solving equations.)
