The Paramount+ gang drama MobLand eliminated its primary antagonist, Richie Stevenson, after just one season, but what's replacing him is far worse for the Harrigans and their fixer, Harry Da Souza. The rivalry between the Harrigans and the Stevensons in the London criminal underworld evolved into a full-scale war thanks to the murderous actions of the elder (and youngest) Harrigans, and Richie Stevenson appeared to have an edge thanks to his patience, calm under pressure, and intel from the rat in the Harrigans' organization, O'Hara Delaney.
