Allen will play Liam Walker. Described as smart, slightly smug, but with a strong moral compass, Liam is Walker’s younger gay and conservative brother who has been recently promoted to assistant DA. Liam and Walker are close, but Liam gives his brother no shortage of tough love. Liam has always stayed close to home, often sacrificing his personal life in favor of his family duties. In Walker’s absence, he stepped up to take Walker’s kids under his wing. Liam’s close relationship with Walker’s son and daughter makes Walker slightly jealous.
