The Rookie ABC’s crime drama following John Nolan, a 45-year-old newly divorced man from Pennsylvania, who, after helping police officers during a bank robbery in his hometown, moves to Los Angeles to pursue a new career as a police officer with the Los Angeles Police Department. The series, which premiered in 2018, follows the personal and professional lives of Nolan and other officers, detectives, and sergeants with the LAPD.

Dr. Blair London (played by Danielle Campbell) was introduced in The Rookie Season 6 as a psychiatrist assigned to the LAPD to help Aaron Thorsen process the trauma of being shot and almost dying in the Season 5 finale. Later in the season, Sergeant Tim Bradford also starts to see her for counseling. Since her debut on The Rookie, fans have theorized that Dr. London wasn’t exactly who she seemed. Those suspicions were proved right at the end of Season 6 when the therapist was confirmed to be in cahoots with villain Monica Stevens. Read on for a refresher on who Monica on The Rookie is and what her connection could be to Dr. Blair London.
