Patrick Keleher debuted in Season 7 of The Rookie as Seth Ridley, one of the new police recruits, fresh out of the academy. Throughout Season 7, it appeared that Ridley was harboring a dark secret. He told conflicting stories that didn't line up, something that his training officer, Lucy Chen (Melissa O'Neil), caught onto and found suspicious. Eventually, the truth was revealed that Seth is a pathological liar who constantly uses false statements to get out of trouble. It started in his youth, later continued into his adulthood, and became habitual. Seth then became one of the most hated characters of the season, and perhaps, the show's entire history. However, despite all the trouble Seth caused, his last episode left a glimmer of hope. Seth Ridley's latest appearance in "The Return" should not be the character’s last. Seth must make a comeback in Season 8 to bring his redemption arc full circle!
