He searches for a photograph of Isabel posing in front of a shed, the flower prominently beside her. James then reaches out to Hazel, summoning her to the station as he believes he might know Izzy's whereabouts that fateful night.
Anton escorts Kalana to the shed, capturing a moment of her framed against the door. Upon Hazel's arrival at the station, James unveils his theory, accusing Anton of being the killer. Hazel reveals that Anton and Izzy used to retreat to the shed for privacy, confessing that Anton is the father of Kalana and he had taken her there too.

He narrates how Izzy had brought them together, yet it was she who had kept him apart from his daughter. As James and Hazel arrive on the scene, they make a desperate attempt to extricate Kalana from Anton's grasp.
Anton informs everyone that Izzy had ended their relationship at the formal, but that night had not been the final time he had laid eyes on her. Approaching her at the service station, Anton insistently claims that nothing had transpired between him and Tasha. Victor enters the picture, arriving on a roaring motorbike. Anton, finally weary of deceit, confesses that Izzy had passed away instantly. Victor, convinced of his son's unwell state, trains the rifle's sights on Anton, commanding him to step away from the knife. Anton reluctantly releases Kalana, allowing Victor to rush to his son's side. James manages to wrestle the gun away from Victor, who now finds himself facing James's own firearm, accused of beating his son to silence him. James suspects that Isabel had stumbled upon them there.
Seeing the motorbike, Isabel decides to follow its trail. Upon reaching the shed, she retrieves the boys' boots and swaps them with her own shoes in the washing machine. Rushing back to check on Kalip, Izzy discovers that he believes his boss had murdered his brother. He leads her to his digging site, where she notices his bleeding wound. Izzy provides him with something to dress the cut, but the sound of the returning motorbike sends her scurrying through the wisteria plants, away from the shed.
Victor returns, reassuring Kalip that everything will be alright, as he possesses the medicine needed. However, upon realizing that someone else had been there, Victor is consumed by panic and shoots Kalip. Discovering Isabel's cloth, he is compelled to go after her. He tracks her down to the service station, where she is with Anton, and beats her mercilessly with the rifle. James intervenes, leading Victor away, while the bike Izzy had been riding is later discovered abandoned.James instructs Dale to contact him immediately upon discovering the boys' bodies. At the precinct, James learns that Vic has relinquished his right to have legal counsel present.

Victor contends it was a matter of self-defense, asserting that one of the boys broke into his home with intentions to molest his infant daughter.
A flashback unfolds where Victor steadfastly refuses to allow them to drink until their chores are done. Kalip eventually succumbs to exhaustion and passes out. They head to Victor's house to slake their thirst from the outdoor faucet. Overhearing the baby's cries, Kalip ventures inside to check on her. Victor catches him and flies into a rage. They attempt to apologize, but Victor retaliates by assaulting Niman, prompting Niman to yell for Kalip to flee. Victor gives chase on his motorbike, while Isabel looks on helplessly. Victor explains that he didn't seek help because authorities would falsely accuse him of assault. He intended to leave them be until the boy recovered, but an infection set in. On the night of the formal, Victor visited the SES shed to retrieve antibiotics, claiming he was returning to assist the boy but found him already deceased. When questioned about whether he forced Billy off the road, Victor mentions Billy's involvement in drug dealing.
Victor maintains that Billy was just as bad as the boys, alleging that Billy had dropped them off at his place. Furthermore, Billy was causing a commotion at the pub, so Victor couldn't risk him remembering the incident. James informs Anton that he is free to go but advises him to surrender his passport. James finds himself uncertain of his next steps but believes Victor will spend the remainder of his life behind bars. Katherine enters shortly thereafter, breaking down in tears.
Outside, Kalana inquires about Anton's reasoning for taking Izzy's hair. Anton clarifies that he couldn't abandon her in such a state, so he took her to the cemetery and laid flowers in her honor.
He vowed to her that one day, he would muster the strength to confront him head-on, armed with undeniable proof. With tender care, he snipped strands of her hair, entrusting them to a time capsule as a token of their shared resolve. Kalana is convinced that she engaged with the entities in ways Anton never could, bridging gaps he found insurmountable.
Hazel, uncertain about Anton's potential role in Kalana's life narrative, makes it clear that it is her journey to navigate. She asserts that until she is mentally prepared, Anton must remain a distant shore in her ocean of personal growth. Six weeks pass, and Hazel provides Kalana with funds for her trip to the town accompanied by Meg. Meanwhile, James pays Hazel a visit, returning the lock of Isabel's hair, his heartfelt hope that he too might uncover long-sought answers mirrored in her eyes.
