The Coffee Table

Jesús buys the table to assert his independence and decision-making power in the relationship. María had critiqued the salesman's pitch so effectively that Jesús felt stripped of his ability to make his own choice. By purchasing the table despite her objections, he essentially tells her that he still gets to decide, even if the decision is against her preferences. This tension reflects underlying power dynamics in their relationship as new parents.

The table's glass pane shatters during the scene where Jesús is alone with the newborn Cayetano. While the salesman claimed the glass was unbreakable, the actual mechanism isn't fully explained in the summary, the shatter simply occurs, triggering the tragic accident. This marketed reliability becomes a dark irony, as the very feature promised as safe becomes the instrument of tragedy.

The salesman's overzealous claims about the table's durability foreshadow the devastating failure of that claim.

Jesús is alone with baby Cayetano while María is out buying groceries and wine. As Jesús struggles to calm the crying infant, the glass coffee table shatters, presumably due to some pressure or impact, and the falling glass causes fatal injuries to the newborn. The exact moment and mechanics aren't detailed, but Jesús returns to find the baby decapitated, with the severed head left under a chair.

Jesús attempts to shield María from the traumatic reality because he knows the accident occurred while he was solely responsible for their child. Overwhelmed by guilt and shock, he panics and tries to manage the situation by cleaning up and hiding the body before she returns. His desperate attempt to control the narrative reflects his inability to confront both the horror of what happened and his role in it.

Jesús retreats to the bathroom and writes a suicide note because he sees no way out of the catastrophic situation. He's traumatized by the accidental death of his child, guilt-ridden over being the sole caretaker when it happened, and unable to face María with the truth. The note represents his complete mental breakdown and his attempt to pre-emptively end his own life before dealing with the consequences of the tragedy.

The evening escalates chaotically as the truth unravels. Ruth's dog discovers the baby's severed head, triggering Jesús into catatonia. María, under extreme psychological pressure, breaks down completely and grabs the baby's head, rushing to the balcony. The authorities eventually arrive to find both Jesús and María dead alongside their decapitated child. The exact sequence of their deaths isn't specified, but the cumulative trauma leads to their suicide or fatal breakdown.

María experiences a complete psychological breakdown when she finally learns the truth about Cayetano's death. The combination of the shocking discovery, the stress of hosting guests, Cristina's pregnancy announcement contrasting with her loss, and Jesús' erratic behavior proves overwhelming. She grabs the severed head and rushes to the balcony in a moment of acute trauma, representing the complete shattering of her sanity.

The salesman returns to deliver the replacement screw that Jesús had requested earlier, completely unaware of the tragedy that has occurred in the apartment. His arrival is darkly ironic, he shows up at the worst possible moment and even attempts to flirt with Jesús while the aftermath of the accident is still unfolding. This adds a layer of absurd black comedy to the horror, highlighting the cruel timing of ordinary life intersecting with catastrophe.

Ruth's dog follows its senses to the location where Jesús had hidden or placed the baby's severed head, leading to the traumatic discovery during the chaotic dinner party. The dog's detection triggers the final unraveling of Jesús' fragile state, pushing him into catatonia as the truth becomes impossible to conceal from the guests.

Carlos, visibly traumatized and trapped in a police car after the events, utters "La mesita del comedor" (which translates to "the little dining table") as a haunting final line. This phrase, echoing the coffee table that started the tragic chain of events, represents how his mind fixates on the mundane object that indirectly caused all the devastation. It symbolizes the inexplicable nature of tragedy, how something as ordinary as buying furniture could lead to such horrific consequences.
