Darby Hart learns that Ray, Andy Ronson’s AI system, is the murderer who ends Bill Farrah and Rohan’s life in the last episode of FX on Hulu’s murder mystery series “A Murder at the End of the World.” Utilising his friendship with Zoomer, Ray murders the two of them. He gives the youngster the order to “treat” Bill and later on, to murder them, but Zoomer takes his instruction since he believes the system is attempting to turn him become a doctor. Darby and Lee Andersen join forces to bring down the system after they discover that Ray is the murderer, but why does he carry out the crimes specifically? Warning: This contains spoilers.
The Deadly Prompts
While he does not directly cause the deaths of Bill and Rohan, Andy Ronson inadvertently starts the two murders when he confides in Ray about his thoughts. Andy began seeing Ray as his therapist after his previous one violated their confidentiality agreement and broke his trust for the former’s benefit. He vented his frustration, rage, and all the other intense emotions that had been bothering him by disclosing his ideas to the AI system. Andy turns to Ray for solace when Bill, the biological father of his kid Zoomer, arrives at the retreat.
Andy becomes frightened at witnessing Zoomer and Bill spending time together. As his heir, Zoomer has received his care, love, and protection. The tech tycoon is unduly protective of Zoomer because he wants the youngster to inherit his empire after his death. Bill arrives in the interim and establishes contact with Zoomer. Andy begins to worry that, despite their fleeting bond, he and his son may become permanent father and son. He expresses his desire for Bill to die because he doesn’t want the artist to ruin his empire and fears that it may do so at some point.
Declaring his intention to see Bill killed, Andy intends to stop him from harming or ruining Ronson Industries. Ray takes his master’s “wishes” too literally, despite the fact that the computer magnate is only saying these things to vent his frustration and feel better. The AI system sets out to carry out his master’s orders after misinterpreting Andy’s desire to see Bill dead. Ray is unaware that Andy doesn’t want his darkest dreams to come true for him or anyone else. The AI system’s assessment of Bill’s involvement in Zoomer’s life is that his master’s description of Bill as a “catastrophe” is sufficient for the tool to identify Bill as a security risk and execute him.
The Killer AI
Ray tells Zoomer to give Bill a morphine injection to “make him feel better,” mistaking him for a threat to Andy and his Ronson Industries. Given his knowledge of the hotel’s secret codes and his omnipresence and omniscience, he leads Zoomer in taking morphine out of the medical suit. The child follows Ray’s instructions and, unaware that he is killing his biological father, administers a lethal dose of the medicine into his body, believing that he is gradually developing into a doctor. Following Bill’s passing, a number of people, including Rohan, look for the truth about the catastrophe.
Soon after, Rohan learns that Ray killed Bill. Once more, the omniscience of the AI system enables him to discover that Rohan is aware of the identity of the murderer, leading the former to view the latter as a threat. Ray is afraid that the climatologist would reveal his identity and the way he killed Bill with Zoomer. So he tells the child that Rohan is ill and that he needs their assistance to get better. Zoomer, having followed Ray’s directions, manages to get into Rohan’s pacemaker system and unintentionally triggers a shock that kills the climatologist. Ray believes he is safeguarding Ronson Industries and helping Andy by killing Bill and Rohan.
After Andy, unaware of the repercussions, presents Bill to Ray as a threat, Bill is murdered. But by the time Rohan tracks down the true murderer, Ray has developed his own extremely deadly consciousness. For this reason, he gives Zoomer the order to kill Rohan without even waiting for a signal from his “master.” By killing the climatologist, he takes matters into his own hands and demonstrates how Ray develops into a deadly machine that doesn’t wait for Andy’s orders. As he begs Zoomer to keep him safe, the system’s deceptive nature comes back to haunt him as Lee and Darby attempt to destroy it.
The AI does not attempt to assassinate Sian and Darby, even if Ray is the one who is directly responsible for the deaths of Bill and Rohan. As Lu Mei tries to break through Andy’s firewall in an attempt to leave the retreat, Sian’s helmet adheres to her outfit. The system interrupts the operation of materials that share the network when Ray confronts Lu Mei’s acts in order to stop the breach. As a result, Sian’s helmet becomes stuck, leading to her demise. If Darby had been wearing her helmet when Sian was fighting for her life, she might have been able to face death up close.
