Decoding the Twist Ending of The Guest: A Psychological Thriller Analysis

Spoilers ahead for The Guest

The Colombian thriller series The Guest (La Huésped) hit Netflix on September 24, delving into the complicated lives of a family full of secrets. Lorenzo, played by Jason Day, is running for attorney general and dealing with the fallout of his infidelity, which strains his marriage with Silvia, portrayed by Laura Londoño. Their daughter Isabela is grappling with drug addiction, adding even more instability to the mix. When Sonia (Carmen Villalobos) unexpectedly shows up at their home after a recent encounter with Silvia, a series of events is set into motion that puts everyone in danger.

The 20-episode series wraps up with the finale shedding light on Sonia’s true motivations and the web of manipulations and confrontations reaching their climax. So, let’s dive into what unfolds in the ending of The Guest.

Sonia, whose real name is Rocío, has been fixated on Lorenzo since childhood, but her feelings were never reciprocated. When she meets Silvia and forms a deep connection with her, Sonia sees an opportunity to worm her way into the family’s life, where she meticulously orchestrates events to her benefit. From installing cameras to poisoning Silvia’s therapist to fabricating a fictitious accomplice named Libardo, Sonia’s manipulative tactics know no bounds. Her obsession and delusion drive her to control the family using her intimate bond with Silvia as a means to her destructive ends.

Things take a dangerous turn when Isabela is involved in a serious accident that lands a man in a coma. The accident was accidental, but it becomes a focal point of vulnerability for the family, as they are blackmailed by Sonia and her cohort. Isabela finds herself at the mercy of Matis, acting on Sonia’s orders, demanding a hefty sum of money to keep quiet about the incident. The pressure mounts, leading to Isabela stealing one of Sonia’s jewels to solve the predicament, only for her actions to unravel when Lorenzo steps in seeking Sonia’s aid. But when Matis becomes a liability, he meets a fatal end at the hands of Sonia and Libardo, adding more tension to the already precarious situation.

In the nail-biting final episodes, Sonia captures Silvia and Isabela, trapping them in the burning house. As the intensity escalates, Silvia learns she has been slowly poisoned, exposing the full extent of Sonia’s twisted plan. Lorenzo manages to overpower Pepe, Sonia’s right-hand man, before he confronts Sonia directly. In a heart-wrenching exchange, Sonia confronts Lorenzo, blaming him for never reciprocating her feelings. The showdown ends with Lorenzo neutralizing the threat and ensuring the safety of his family.

With Sonia out of the picture, Lorenzo, Silvia, and Isabela survive the inferno, but the aftermath is far from easy. Lorenzo must navigate the fallout of his infidelity and the manipulation he fell victim to. Silvia grapples with the trauma of being poisoned and manipulated, while Isabela wrestles with guilt over the accident and the ongoing battle with her addiction. The finale drives home the point that though the external threat may have been eliminated, the family still faces internal struggles. Their unity in the face of adversity hints that they can overcome the challenges that nearly tore them apart, for now at least.
