With only a handful of episodes remaining in The Rookie season 7, the writers can't circle back to every plot, including one of John Nolan and Bailey Nune's most important storylines. The seventh season of the ABC police procedural series contains 18 episodes and nine main characters. Consequently, there isn't much room to thoroughly and continuously develop every story in The Rookie season 7, especially ones that technically have resolutions (no matter how lazy they might be).
