Welcome to The Authority, Slate’s deep dive into the world(s) of HBO’s His Dark Materials. Each week, Slate’s scholars of experimental theology Dan Kois and Laura Miller discuss the HBO series and Philip Pullman’s original trilogy. This week, they cover the Season 2 finale, “Æsahættr”, in which Will finally meets his father, Lee Scoresby visits the Alamo, and Mrs. Coulter puts a kid in a trunk. Plus: an interview with Jack Thorne, the adaptor-in-chief of Philip Pullman’s books. Email: [email protected] Podcast production by Phil Surkis.
