On Call‘s ending left few questions about the murder of Officer Maria Delgado (Monica Raymund) but did leave the audience picturing a second season with more highs and lows for our two new favorite police officers.

Throughout Season 1 of Prime Video‘s newest hit police procedural, Officer Traci Harmon (Troian Bellisario) and Officer Alex Diaz (Brandon Larracuente) worked together to track down Delgado’s murderer after she was brutally shot and killed during a traffic stop. The death hit the entire Long Beach Police Department like a ton of bricks but particularly affected Harmon, who trained Delgado and blamed herself for the junior officer’s death.

Immediately after Delgado’s traffic stop slaying, Harmon was partnered up with Diaz, a rookie entering his 60-day training period. While Lieutenant Bishop (Lori Loughlin) gives Harmon an out, telling her that she doesn’t have to take an underling, Harmon is committed to making sure that Delgado’s fate does not come to another younger officer.

**Spoiler Warning: This article contains heavy spoilers for On Call Season 1**

Throughout the eight-episode first season, we watched as Diaz and Harmon responded to calls both related to and unrelated to the murder of Officer Delgado, who was killed while picking up a shift. Episode after episode, the two cops put themselves in the line of fire, risking their own lives — and the lives of the ones they love — in order to protect the community of Long Beach. Standard stuff for a cop show but life and death all the while.

Harmon, eager to ensure that another freshman officer doesn’t lose their life in the line of duty, spent the entire first season working to teach Diaz everything she knows and mold him into the kind of cop that should be on the force. While the show is riddled with Dick Wolf-isms about policing in the 21st century, Harmon tends to be the cool-headed officer who takes her job seriously and tries to be just. Diaz, hungry to prove himself, is more of a rash character who runs in the direction of gunfire without thinking of the consequences. It’s that dynamic that gives On Call Season 1 the drama and intrigue to propel eight episodes and a killer finale (pun intended).

So did they find Delgado’s killer? Did Harmon finally get the promotion she had been waiting for a long time? Has Diaz earned himself a full badge and gun by finishing his training period and passing with flying colors? Most importantly, did these two officers find a friendship that will forever change them into cops and humans? Okay, maybe that’s not the most important thing but it is something we wondered about since Episode 1.

Here’s everything you need to know about On Call‘s Season 1 finale…

After finding Delgado’s killer, a member of the East Barrio gang nicknamed Maniac, earlier in the season, the final episode came down to the pursuit of Smokey (Lobo Sebastian), who inadvertently acted as the informant to Harmon in finding Maniac. Smokey, a bar owner with connections to the East Barrio gang, had told Harmon that she should stop looking into Maniac, which led to her realization that the wanted murderer was in hiding, not Mexico, as LBPD was led to believe. Even though Smokey didn’t really give anything substantial to Diaz, East Barrio saw it as a betrayal nonetheless, putting a hit out on Smokey and his family.

After realizing there was still a chance for them to catch Maniac, Harmon put her ear to the ground and got to work on hunting him down, barely keeping her fellow officers or superiors in the loop on her independent investigation. In fact, after she used sources and solid police work — with a little bit of coercion — to track Maniac down to a Long Beach motel, she had to answer to Lieutenant Bishop, who asked her how she knew Maniac was hiding out at the motel. At the time, she admitted, believing that they were talking off the record, that she used some off-the-books tactics to find Delgado’s killer. This will come back to bite her, just wait.

In the final moments of Episode 7, “War Machine,” Harmon’s friend and potential new teammate, Sergeant Tyson Koyama (Rich Ting), tells her that they have information that could lead to Smokey’s capture. Koyama, a drug officer, received intel that Smokey was waiting on 50 kilos of fentanyl from China worth more than $1 million. Assuming that he would never leave that behind and flipping his drug runner, Harmon and Koyama stage a sting operation to catch Smokey in the act of receiving the shipment.

Earlier in the episode, Koyama told Harmon that her transfer to the drug team had been approved by his commanding officer and that she would soon be leaving behind her beat-cop days. This only provided further incentive (and pressure) for Harmon to ensure that the apprehension of Smokey went according to plan. While staking out the drug drop, the team realizes that Smokey sent his daughter, Leona (Annabella Didion), to pick up the drugs in his stead. This comes as a shock to Diaz and Harmon, who rescued Leona just days prior after she was beaten to a pulp during a break-in at Smokey’s home. At the hospital, Diaz even was able to get Leona to confide in him and managed to establish a connection with her.

After a tense shootout during the drug drop between Smokey’s own crew and the police, Diaz chases Leona and is shot several times in the chest by her. Before Leona can fire a fatal shot as she stands over Diaz, Sergeant Koyama stops Leona by shooting her directly in the head. Luckily, Leona’s bullets hit Diaz’s bulletproof vest and grazed his shoulder, making his injuries non-life-threatening. After confirming her trainee would live, Harmon chases after Smokey, locating him in a diner and calling for EMS since he had been hit. There, Harmon tells him that Leona is dead and that he will go back to prison and live out his days.

At the hospital, Harmon hugs Diaz as he apologizes for running off and putting himself in danger, something he was told not to do throughout the season. Harmon admits that she is just happy he is alive and the two are interrupted by Koyama, who brings bad news about Harmon’s promotion. According to him, the transfer to the drug team was denied by someone within LBPD, effectively shutting down Harmon’s hopes to finally make career moves. She, of course, thinks that Sergeant Lasman (Eriq La Salle) is responsible for the transfer denial as he has had it out for her this entire season.

After a frosty confrontation with Lasman, Harmon discovers that it was not Lasman who stopped her upward mobility. It’s never spelled out but she quickly realizes that if it was not Lasman, it had to be Lieutenant Bishop, a friend and supposed confidant.

Cut to Diaz’s parole board hearing where he makes his case to the board — including Harmon and Lieutenant Bishop — for why he should be able to earn his badge and gun. After a heartfelt speech about how he is not only a better police officer but a better man because of Harmon, he thanks her for her guidance and friendship. It’s a sweet moment of elation before a bomb completely obliterates his happiness as Harmon makes the recommendation that he should not be moved out of his training period. It’s on her advice that Bishop then resets his parole period, making him restart his 60 days of training. Of course, Diaz thinks that Harmon is just bitter about her own promotion being denied, but really, she tells him that it is the recklessness and urge to “be the hero” that makes her feel as though he has more to learn.

Ultimately, Harmon confronts Bishop about the transfer being denied, saying that she thought their earlier conversation about locating Maniac was just between friends. That’s when Bishop confirms that it was, telling her that any other officer would have been fired for disobeying direct orders and investigating a known cop killer behind superiors’ backs. The elder officer also turns Harmon’s own critiques of Diaz right around on her, saying she too — in her own way — is brash and has a tendency to do what she thinks is right, not what she is told. Ever the optimist, Harmon tells Bishop that if she is going to be forced to suffer through more time as a beat cop, the least Bishop can do is give her Diaz for another 60 days. This, she says, will give her enough time to train Diaz and correct his mistakes in order to make him a better cop.

Season 1 ends with Harmon and Diaz right back where they started, heading out together for a shift patrolling the streets of Long Beach. Not before Diaz hands back the “Get Out of Jail Free” card that Harmon gave him at the start of the season, squashing their beef and giving them a fresh start with a new rotation. It all but ensures that these two have more adventures ahead and much more to learn about the profession from one another, probably in Season 2.

Prime Video has yet to renew the police procedural but given it’s popularity — it’s currently in the No. 1 spot on the streaming platform — we think this isn’t the last we’ll see of these cops.
