The Decision Behind the Cast Switch The producers explained that the series needed a new dynamic to maintain audience interest. „Nathan’s character had grown into a mentor figure,” said showrunner David O. Russell. „We wanted to explore the challenges of a rookie in a modern police department, so bringing in John Nolan allows us to dive into that perspective.” The shift also aligns with the network’s strategy to refresh long‑running shows, ensuring that storylines remain relevant. John Nolan’s first episode features a tense stakeout that tests his resolve. He interacts with seasoned detectives, including a seasoned partner played by former „Law & Order” star Marcia Cross.
