Recap / His Dark Materials S 3 E 5 No Way Out

Angels guide Mary to an uncharted world where she befriends the Mulefa, sentient quadruped mammals. She begins learning their language and experiences visions from the rebel Angels that she will act as the biblical Serpent. Meanwhile, the boatman ferries Lyra and Will across the waterway to the Land of the Dead. They find Roger and Lee Scoresby among the deceased denizens. The Magisterium misled many into believing they would enter Heaven, but they are instead eternally trapped in Purgatory. Harpies harass the dead, but Lyra tells everyone to remember the living world, as it will protect them. Will attempts to slice a hole out of Purgatory, but the Subtle Knife does not work in the lower region; they set off for higher ground. Meanwhile, Mary improvises a spyglass by coating amber pieces with seed pod oil. Through it, she sees Dust escaping the Mulefa's world, slowly killing it. Also, MacPhail and Dr Cooper prepare Mrs Coulter for the incision procedure that will unleash the bomb. However, Dr Cooper experiences guilt and halts the operation. MacPhail kills Dr Cooper and Commander Roke while Mrs Coulter's daemon frees her from the device. MacPhail, willing to sacrifice himself, takes Mrs Coulter's place, but she disables the mechanism before the bomb detonates. When Alarbus tells the Regent Metatron that Will is the new Knife Bearer, Metatron intervenes and triggers the mechanism, killing MacPhail. The bomb detonates in the Land of the Dead.
