| 107 | 1 | "Buzzkill" | James Wong | Molly Green & James Leffler | September 26, 2024 (2024-09-26) | 8LAY01 | 4.93 |
| Hen and Karen make progress with regaining their foster license; Hen notices that Chimney and Mara are growing close. Buck and Tommy help Eddie throw a birthday party for Christopher over video call, but Christopher is vacant and eventually leaves to celebrate with new friends, much to Eddie's dismay. Bobby is now a technical advisor for firefighting TV show "Hotshots;" he is undermined by production, but idolized by the lead actor, Brad Torrence. A truck carrying 22 million killer bees crashes downtown, threatening the lives of a mother and daughter and, later, the attendees of a perfume party. Buck's initiative allows the 118 to handle both situations efficiently, but he is punished by Gerrard for unruliness. Buck later saves Gerrard from a flying circular saw, but knocks him unconscious in the process. Meanwhile, Athena escorts her first fiancé's killer, Dennis Jenkins ("Athena Begins"), to L.A. so he can testify in a trafficking case in exchange for freedom. En route, she detains a fake officer who tries to take Dennis into his own custody; Dennis reveals that someone wants him dead. They board an L.A.-bound plane which, due to the bees obstructing visibility, violently collides with another plane. |
| 108 | 2 | "When the Boeing Gets Tough..." | Bradley Buecker | Ted Griffin & Tim Minear | October 3, 2024 (2024-10-03) | 8LAY02 | 4.92 |
| Before the planes collide, Dennis tells Athena that he is being targeted because the perpetrator of the trafficking case, who was his cellmate, confided in him. The collision kills the pilots of both planes and creates two holes in Athena's — one in the cockpit that incapacitates the co-pilot and another in the back of the fuselage. While Gerrard is taken to the hospital, the 118, via phone call, aids the plane's passengers in treating casualties. Athena attempts to fly the plane herself with the help of flight instructors on the ground and a young aviation enthusiast on-board. The co-pilot eventually awakens, but suffers a heart attack shortly after. Meanwhile, all fire stations are directed to LAX; Buck travels there separately after retrieving Bobby (and Brad) from their show's set and taking a prop fire truck for transport. |
| 109 | 3 | "Final Approach" | Bradley Buecker | Tim Minear & Ted Griffin | October 10, 2024 (2024-10-10) | 8LAY03 | 5.52 |
| Passengers on the plane take turns performing CPR on the co-pilot. The plane's rudder becomes damaged, removing its ability to turn. This eliminates LAX as a landing option; Athena instead aims for the 110 freeway, with Buck, Brad, and Bobby clearing part of it in preparation. The plane is successfully landed, but a fire breaks out while the passengers are disembarking, threatening Athena, who stayed behind to continue CPR on the co-pilot. The fire stations arrive and the 118 and Bobby extinguish the fire and rescue Athena. Afterwards, Bobby deters a pair of detectives from locating Athena and Dennis and the three go to LAX's long-term car park to retrieve a book detailing the trafficker's associates. A detective follows them, reveals himself to be a fake, and shoots at Bobby; Dennis takes the bullet and stabs the detective, allowing for his detainment. Athena passes the book to trusted investigators and later has a heart-to-heart with Dennis, absolving herself of the resentment she held towards him over his past actions. Meanwhile, Gerrard returns to the 118 and is uncharacteristically beholden towards Buck, much to everyone's surprise and confusion. |

Eddie, missing Christopher, confronts the cheerleader's absent father, helping repair their relationship. At her adoption hearing, Mara risks being returned to group housing after the Wilsons are revealed to have continued contact following her removal from their household. Councilwoman Olivia Ortiz, still bitter over her son's death, rebuffs Hen's pleas for mercy before revealing that she was the one who reassigned Gerrard to the 118. After Hen and Bobby inform Gerrard of this, Gerrard convinces Ortiz to shut down the 118 to solve the budget issues. The 118 fights against this in court and Ortiz's reputation is ruined after it is revealed that Gerrard used his bodycam to record his conversation with her and expose all her schemes. With Ortiz's desire for revenge on Hen permanently foiled, Mara is reunited with the Wilsons and Bobby returns to the 118 as captain, with Gerrard taking on his technical advisor role. |

Recuperating at home with Tommy, Buck learns that the corpse was once a boil-covered cowboy who was betrayed by his own posse. Buck awakes the next morning covered in boils, which, coupled with his injury, leads him to believe he has been cursed; Eddie and Tommy remain skeptical. On Halloween, Athena and the 118 deal with various inoffensive calls before responding to a car crash brought on by a man who chased the aforementioned students via car after they egged his home; the excursion kills the man and pins Denny against a house. Denny's heart stops, but, thanks to a blood transfusion from Karen and CPR from Hen, he is revived and recovers at the hospital. Hen and Karen reconcile.

Overwhelmed by the events of the day, he takes a city bus hostage with a kitchen knife that another passenger falls onto when the bus hits spike strips.

Chimney, hearing Athena has been trapped in the building, goes in by himself to help her get out; they learn Graham was impaled, but said nothing because the other civilian, who he previously had been feuding with, needed their help more. This causes Athena to accept what Bobby did for Chimney and the two reconcile after the team saves Graham. Back at the firehouse, Chimney tells Eddie he is not living in Texas anymore and tells Buck he's not transferring, making a speech about keeping the importance of Bobby's legacy alive.
