The sixth episode of Apple TV+'s Cape Fear, titled "Possum," marks a significant high point for the series, expertly blending camp, dread, and unexpected action into a "bonkers hour of television." The episode effectively functions as a series of interconnected bottle episodes, delving into Max Cady's past and the escalating paranoia of the Bowden family.

"Possum" opens with an extended flashback to Max's time in prison. Following a brutal encounter with a white supremacist gang, Max is taken under the wing of an elderly inmate, referred to as "Padrino." This flashback sequence includes a jarring scene of Max undergoing invasive brain surgery before his induction into a mysterious religious order, the "Sons of Changó," which may explain the recurring presence of candles and altars throughout the series.

Back in the present, the Bowden family takes Max's threats more seriously, upgrading their home security. Despite efforts to keep the children constantly monitored, Natalie expresses her displeasure. Tom seeks legal counsel regarding Max's harassment, but the lack of evidence and political pressure leave him with few options.

The episode then features a rapid succession of scenes: a threatening phone call to Max, Max assisting Natalie with a confrontational podcaster, Anna hinting at her knowledge of Tom's infidelity, and Natalie experiencing a dream involving Zack. These quickly lead to the episode's most memorable set piece.

During a sultry evening with a broken air conditioning unit, the Bowden family begins to exhibit strange behavior. Following a confrontation with Tom about an "almost" affair, Anna notices the wallpaper moving. Tom discovers that their beverages have been spiked with the acid he had been microdosing for stress. What follows is a masterfully shot and acted sequence, simultaneously tense and darkly humorous. The family's paranoia about the police and the potential removal of their children heightens the tension, while Zack's disoriented moans and Tom's contemplation of his shotgun add to the surreal atmosphere. The situation is further complicated when Anna's anger management counselor may overhear the events via a video call. The family's perception of reality blurs as a drone enters the house, leading Natalie to retrieve Tom's shotgun and destroy it.

This sequence is described as an "amazing scene, a one-act play within an episode laced with slapstick and paranoia." The combination of music and cinematography creates a "technicolor feast" that exposes suspicions, builds drama, and reveals hidden character traits.

The following morning, a sober Anna and Tom confront Max across the street. Max, nonchalantly eating pig's ears, disarms them, reveals he has stolen their cat, and expels them from his house. He makes a disturbing proposition regarding Anna carrying his child and demands that Tom and Anna cease practicing law and issue a public apology. Tom's demand that Max leave them alone is met with a chilling "You'll have to kill me," to which Tom replies, "I know," setting the stage for the season's finale.

The narrative then returns to Max's prison time, where he confronts Padrino, revealing his knowledge that Padrino allowed him to be beaten to become part of his order. This revelation leads to Max murdering Padrino with a prison shank.

In the present, Tom finally asks Anna if she slept with Max when she was his lawyer, a question the review notes has been anticipated since the series premiere. Anna vehemently denies it, but their conversation is interrupted by a smoke alarm and a fire in the family's den. After Tom extinguishes the fire, he discovers Zack's severed toe. Anna and Zack discover a secret passage in his closet. Tom investigates the passage, falls through the floor, and lands in a hideout. Anna breaks through the drywall, revealing a possum. The discovery escalates when a hand snatches Tom back into the wall, belonging to Neveah, who attacks him before being subdued by Anna. The episode concludes with bloody footprints leading from Zack's room across the street to Max's house.

The episode's ending is described as "truly wild" and an "excellent episode after a somewhat sagging middle run." "Possum" successfully answers key questions in an engaging and surprising manner, propelling the narrative forward. The pacing alternates between "top-tier comedy leading into quiet drama followed by gonzo action."

While acknowledging minor drawbacks such as lingering subplots (like Max's restaurant aspirations) and occasional opacity in character motivations, the review praises "Possum" as a "brilliantly acted, sometimes uproarious thrill ride" that could serve as a template for the remainder of the season.
