In the poignant fourth episode of "Don't Come Home," titled "Panida," the narrative shifts to the past, focusing on the life of Panida, Varee's mother. Set in 1991, the episode explores the strained relationship between Panida, a dedicated director at a local hydraulic dam, and her young daughter Varee, who longs for her mother's attention. The story unfolds with Varee eagerly anticipating a beach trip with her parents, only for Panida to cancel at the last minute due to work commitments, a decision that deeply disappoints Varee.

Panida's preoccupation with her work at the dam is palpable as she and her crew conduct constant tests on the machines. In a chilling twist, Panida encounters a mysterious vortex in the machine room, from which a woman's shoe falls—a shoe that she later realizes is her own. This surreal event plants the seed of a time-bending concept that will later consume Panida's life.
The tension at home is high, with Varee's father, Wat, expressing his frustration over Panida's constant absence. The family dynamic is strained to the breaking point, culminating in a tragic car accident that claims the lives of Wat and Varee. The accident serves as a catalyst for Panida's descent into grief and self-reproach, as she realizes the error of her ways in prioritizing work over family.
The episode takes a dramatic turn when Panida, in her despair, contemplates suicide at the dam, losing one of her shoes into the vortex. This event triggers a revelation: the shoe that fell from the vortex earlier is the same one she lost, suggesting a connection across time. Driven by this discovery, Panida becomes obsessed with building a time machine, hoping to travel back to March 1991 to save her daughter Varee.
Despite several failed attempts, Panida's persistence pays off when Min, not Varee as she initially believes, appears in the cubical machine. Panida's confusion quickly turns to realization as she understands that Min has traveled through time. In an attempt to make up for the lost time with Varee, Panida begins to act as Min's mother, creating a poignant parallel to her past mistakes.
The episode reveals that the Min Varee sees in the future, playing in a study wearing a mask, is the same Min who has time-traveled. Panida's use of the time machine creates a vortex, and in a heart-wrenching scene, Varee from the future is sucked into it, arriving in 1992 in front of Panida. The time machine's glitch is suggested as the reason Varee saw glimpses of a masked Min in the future.
The episode concludes with a powerful and emotional scene where Varee, now in the past, opens her eyes and calls Panida 'Mom,' a moment that takes Panida by surprise and fills her with a mix of joy and sorrow. This encounter not only marks a significant turning point in the series but also highlights the theme of regret and the lengths one might go to correct past mistakes.
"Panida" is a powerful exploration of a mother's love, regret, and the desperate struggle to change the past. The episode masterfully blends elements of science fiction with a deeply emotional narrative, creating a compelling and heart-wrenching tale. The performances are raw and captivating, particularly the portrayal of Panida's journey from a work-obsessed mother to a woman willing to defy the laws of time to save her child.
The episode leaves viewers with a profound sense of the consequences of neglecting loved ones and the potential costs of second chances. As the series progresses, the implications of Panida's actions and the true nature of the time machine become increasingly intriguing, promising a thrilling and emotional journey ahead. "Don't Come Home" continues to captivate with its atmospheric storytelling and the slow unraveling of a family's dark secrets, making it a must-watch for fans of psychological thrillers and supernatural mysteries.
