He planned to scapegoat Lamb’s team for the entire security crisis.Jackson Lamb, however, is always playing the long game. According to reports from entertainment analysts, his character consistently outmaneuvers his superiors. Lamb used secretly gathered blackmail material to force Whelan’s resignation.This political maneuver saved the Slough House department. It also secured the reinstatement of agents Roddy Ho and Molly Doran. The power shift resulted in Diana Taverner finally ascending to the role of First Desk.

The Symbolism of the Final Scene
