Benjamin Marshall Lawson, known professionally as Marshall Law, is the deuteragonist of the series Let's Play. He is a famous ViewTuber who runs the gaming channel Lawman and unknowingly served as a major inspiration for the protagonist Sam Young before his review of her game Ruminate triggered a wave of negative feedback from his audience. His real name is rarely used publicly, and he maintains a confident, humorous online persona that contrasts with his private struggles. He is described as having a broad sense of humor and a gift for making people smile, though a fellow character labels him a narcissist; beneath this exterior, he struggles with depression and a fear of being unwanted or unloved, which drives his desire for appreciation and connection. His role in the story begins as an antagonist whose careless criticism derails Sam’s career, but after moving into the apartment next door, he evolves into a neighbor, friend, and eventual romantic interest. Key relationships include his protective dynamic with his sister Eva and his complex, growing bond with Sam, which forces him to confront his own vulnerability and the ethical weight of his influence. He is reluctant to open up about his emotional struggles, fearing rejection, but the narrative shows him gradually offering Sam genuine support, such as deleting a high-engagement video to protect her privacy. Notable abilities include his skill as a gamer, his charismatic streaming presence, and the significant sway he holds over his fanbase—a power he must learn to wield responsibly. His development involves reconciling his public brand with his private identity, facing a public relations crisis, and beginning to let down his defensive barriers.
