What happened in The Rookie season 7 episode 10?

The Rookie season 7 episode 10, titled Chaos Agent, opened with Officer Lucy Chen and her rookie, Seth Ridley, assigned to watch over one of three teenage girls recovering in the hospital after being stabbed during a park altercation.
The stabbing was linked to a larger gang conflict, and Lucy and Seth’s job was to ensure nothing happened to the injured teen while she remained under hospital care.
During their assignment, Seth unexpectedly ran into his former oncologist at the hospital. Lucy overheard their conversation and sensed something was off. Seth claimed his cancer had returned and that he switched doctors due to LAPD insurance, but his former oncologist seemed confused. Suspicious, Lucy asked Luna, Sergeant Grey’s wife, about Seth’s new doctor. Luna revealed the oncologist had a reputation for falsifying diagnoses for profit.
Lucy’s suspicion grew, and she later shared her concerns with her fellow officers, including Sergeant Grey and Tim Bradford. They began investigating Seth’s situation more closely.
Their suspicions were confirmed when it was revealed that Seth had lied about more than just his cancer diagnosis. The investigation into his behavior during his training was also revealing. Lucy had noticed several discrepancies in Seth’s actions, and the team decided to confront him about his lies.
The confrontation took place in a nearby hospital room. Grey and Bradford were already there, waiting for Seth. They informed him that they had been briefed on his multiple lies during his training, including his false cancer diagnosis and other fabrications.

The situation quickly escalated when they demanded that Seth submit to a blood test to verify his cancer diagnosis. Seth, visibly nervous, refused to comply, claiming that it was unfair for them to question something so serious. However, Grey made it clear that if Seth refused, he would be fired immediately.
Seth, in a last-ditch attempt to keep his job, pleaded with them, saying, "I can’t lose this. I love being a cop." But his protests fell on deaf ears. He refused the blood test, which ultimately led to his termination. Grey instructed Seth to turn in his badge and gun, and he was escorted out of the station.
As Seth left, he claimed he would sue the LAPD for medical discrimination. The Rookie season 7 episode 10 ended with Seth’s downfall, and fans were left wondering how his firing would affect Lucy, his training officer.
The Rookie season 7 episode 10 is available to stream on Hulu.
