The real meat of the episode, though, still lay ahead. Some have criticised recent seasons of the show for resorting to thriller pyrotechnics – gunplay over nuance. That certainly wasn’t the case here. Instead, creator Jed Mercurio treated viewers to an attempt at achieving moral closure for the protagonists – which may tell its own story about whether or not Line of Duty has a future beyond this season. Many viewers harboured dark fears about Ted Hastings. Surely not Ted? Well, no. But there were undeniably questions to answer, and answer he did. The most affecting interrogation scene yet involved Hastings spilling his secrets relating to John Corbett’s death and Steph Corbett’s money, and trusting in Arnott and Kate Fleming, whose pained, “disappointed not angry” faces were at once amusing and mildly heartbreaking.
