Al pilots the submersible toward the Trieste station while Luke watches the structure loom out of the dark. Its long, snakelike design and unfamiliar geometry unsettle him. Al voices her own unease but brings the submersible in and docks. She tells Luke to go in first while she monitors the connection from the controls.
Luke opens the hatch, and a cool, cave-like smell drifts in. He peers into the darkness and spots something that startles him into stepping back.
As Luke hesitates, a childhood memory surfaces of a barbershop mirror that revealed hidden angles. Al asks what is wrong, and Luke dismisses it as a visual trick. An inner voice tells him to stay out, but he fights it and propels himself through the hatch.
Luke lands hard in a freezing, lightless tunnel as the hatch closes. The temperature bites through his suit. Overhead, he hears scurrying footsteps, then a boy’s laughter. He whispers his missing son’s name. As movement approaches through the dark, a shape resolves into a panting dog that stops short, friendly but trembling.
Al forces the hatch and joins Luke, explaining that the porthole lock malfunctioned. Her flashlight reveals patches of friction tape and foam stuffed into seams, signs of makeshift repairs. The Trieste is running on minimal phantom power.
The dog stays close. Al identifies her as Little Bee, one of Clayton’s specimens—there were two dogs, Little Bee, or Pchyolka, and Little Fly, or Mushka, named after the doomed dogs that the Soviet Union sent into space. A scream echoes from deeper in the station. Al sprints toward the sound, and Luke follows with a shaking Little Bee.
They reach a locked containment hatch at a dead end. Al listens, then dismisses the scream as likely steam from a release valve. She explains the hatch only opens from the other side, trapping them. As Luke peers through the porthole, a man’s wild-eyed face slides into view. The man’s expression suggests danger, underlining that they cannot pass.
Al identifies the man as Dr. Hugo Toy, a chaos theorist nicknamed “Hugo the Horrible” for his bleak worldview (109). He locks eyes with them and mouths, “You are not who you are…” (109). He then produces a scalpel and pulls it across his throat without breaking the skin. Al concludes that Toy will not open the hatch, forcing them to retrace their path.
On the way back, Al explains that spending too much time this far underwater can cause a psychosis that they call, colloquially, the “sea-sillies.” Luke questions his own grip on reality but keeps the laughter he heard to himself. They return toward the sub to assess other options.
Luke’s thoughts go to the past. He plays hide-and-seek with his young son, Zachary, at a park. While he counts, he hears a zippering and sucking sound from the woods where Zach ran. When he goes to find him, Zach is gone. An extensive search turns up nothing. The loss breaks his marriage to Abby and hollows out his life. He fixates on his vanished son and sometimes wishes for the memory loss of the ’Gets.
Al heads off to attempt a remote unlock of the hatch from a different access point, leaving Luke and Little Bee. Luke finds and pockets a black-stained notebook labeled Psych Report. The station lights cut out. Unsettling slithers and chittering sounds creep closer. Luke remembers the night he awoke to Zachary’s screaming, only to find a giant millipede in his son’s pajamas, and he envisions a giant, many-legged thing bearing down on him now.
The locked hatch behind him pops open with a wedge of light. Luke falls backward through it, and Clayton greets him.
Clayton helps Luke up with a cool manner. Luke rebukes him for abandoning Little Bee; Clayton blames Toy’s interference. Luke presses him about the garbled transmission that called him down, but Clayton states he did not send it. Luke reports that Dr. Cooper Westlake is dead, and Clayton absorbs the news without emotion.
Al rejoins them and confirms that the transmission existed, suggesting Clayton sent it while sleepwalking. He rejects the idea but allows them to remain in the station, warning them not to obstruct his work.
Clayton leads them through junctions to a horizontal crawl-through chute. They emerge into a central lab ringed by five hatches. One hatch, marked with the initials LW, does not open, and something dark is spread across its porthole, blocking their view. The lab includes a large viewing window of the ocean outside. Clayton routes power to exterior spotlights, washing the seafloor in a pale glow.
A sheet-like drift of ambrosia glides past the window, and Clayton notes that it now comes toward them. Luke notices Al staring fixedly at the locked LW hatch; Little Bee barks and breaks the moment. A distant knocking echoes; Clayton dismisses it as Toy.
Fatigue hits Luke hard. Al guides him to Dr. Westlake’s old bunk room. Inside, Luke finds Westlake’s laptop, sticky with a dark residue. On the desktop are three audio files labeled Contact.
Luke listens as Westlake’s voice charts a progression. In the first recording, Westlake describes a black hole opening in his lab wall, growing larger and drawing bees while repelling other animals. In the second, he says the hole has doubled, and he has begun a system of knocks and responses with something on the other side. In the third, he reports that the microphone gets pulled into the hole. He hears buzzing, grinding, and his daughter’s laughter within. He insists the entities will help him, sounding increasingly paranoid.
Luke considers whether Westlake’s account records true events or a man having a mental health crisis. Exhaustion overtakes him. A pleasant memory of Abby shifts into a nightmare as he falls asleep. He opens his eyes to the bunk room’s porthole and sees faces pressed there—Clayton, Al, Westlake—each distorted. The faces stabilize into Zachary, who laughs and tells Luke he cannot get free. The vision leaves Luke shaken and unsure where the nightmare ends.
The physical entry into the Trieste marks a critical transition, establishing the station as a malevolent, sentient environment. The initial description of the station’s architecture, with its strange geometry that feels both unnatural and despairing, moves beyond technical detail into architectural horror. The description of the structure as a coiled, waiting predator frames the descent as a journey into the belly of a beast. Luke’s psychological reaction, a feeling of his soul dwindling as the Trieste fills that space, confirms that the station is an active antagonist that is already beginning to prey on his psyche. This initial encounter reframes the deep from a physical location to a symbolic representation of a hostile, alien consciousness. The subsequent journey through the station’s cramped tunnels, described as a digestive tract, reinforces this idea. The narrative structure, which forces characters through these oppressive spaces, mirrors their psychological entrapment and the slow erosion of their autonomy.
The immediate aftermath of this entry intensifies the exploration of The Fragility of Mental Health Under Extreme Pressure. The appearance of Dr. Hugo Toy, a chaos theorist, provides an early example of the deep’s psychological toll. His silent, repeated mouthing of the phrase, “You are not who you are” (109), acts as a thematic statement for the entire novel, suggesting a fundamental breakdown of identity. Al provides a rational explanation with her description of “sea-sillies,” a form of confinement-induced psychosis. However, the narrative immediately complicates this with supernatural occurrences, such as the child’s laughter that only Luke hears. This juxtaposition creates a persistent tension between scientific rationale and cosmic horror, leaving the characters uncertain whether the ensuing events are products of mental decay or genuine supernatural contact and imbuing the narrative with the same ambiguity. The station itself becomes an agent of this breakdown, its disorienting architecture and oppressive atmosphere acting as catalysts that exploit and amplify the characters’ psychological vulnerabilities.
Central to this psychological deconstruction is the theme of The Vulnerability of Unresolved Trauma, which the narrative explores by juxtaposing the external horrors of the Trieste with the internal terror of Luke Nelson’s past. The inclusion of a detailed flashback in Chapter 32, to the day of Zachary’s disappearance, is a structural choice that functions not only as backstory but also as the key to Luke’s character, establishing his unresolved grief as a profound vulnerability. The narrative positions this trauma as a pre-existing wound that the forces within the Trieste can exploit. Luke’s waking nightmares and hallucinations—most notably the vision of a giant millipede drawn from a traumatic family memory—are not random terrors but targeted manifestations of his deepest fears and guilt. The environment does not simply create fear; it curates it from the raw material of memory, suggesting that the abyss’s true power lies in its ability to weaponize an individual’s personal history against them. The final vision of a mocking, menacing Zachary confirms this, transforming Luke’s most profound loss into an instrument of his own psychological torment. With this construct, the novel connects to the premise of a seminal work of science fiction, Stanislaw Lem’s Solaris (1961), shifting the setting from space and an unexplored planet to the equally unknown environment of the world’s deepest ocean trenches.
Dr. Westlake’s audio recordings, discovered by Luke, introduce the symbol of the holes while simultaneously serving as a case study in Scientific Hubris and the Perversion of Knowledge. The recordings document the appearance of a “hole” in the lab wall—a physical and metaphysical breach. Westlake’s shift from detached scientific observer to paranoid participant illustrates the corruption of the intellectual pursuit. His initial curiosity morphs into a possessive mania, as revealed when he declares of his finding, “This is…mine. My discovery” (144). This moment crystallizes the theme of hubris, where the quest for knowledge becomes a selfish and ultimately self-destructive endeavor. The hole itself symbolizes a gateway to an incomprehensible dimension, and Westlake’s attempts to communicate with the entities beyond it represent humanity’s arrogant belief that it can reason with forces that defy its understanding. Furthermore, the transformation of his bees—which become agitated and aggressive—connects to the recurring insect imagery, representing the perversion of natural order and the subsuming of individual will into a malevolent hive intelligence.
The dynamic between Luke and Clayton Nelson further examines both the perversion of intellect and the nature of trauma. Their reunion is not one of familial support but of immediate friction, establishing them as psychological foils. Clayton represents the pinnacle of detached, amoral science; his cold reaction to Westlake’s death and his dismissal of the transmission by stating he has no need of Luke reveal a man governed by logic devoid of empathy. His focus is entirely on his research, a pursuit that has blinded him to the human cost and the dangers around him. Luke, conversely, is defined by his empathy and his overwhelming grief. While Clayton’s intellect has been his shield against the world and his own traumatic childhood, the narrative suggests that this detachment has become his greatest weakness, allowing him to be manipulated by forces he believes he can control. Their shared traumatic childhood produced two different responses: Luke’s hyper-empathy and Clayton’s intellectual fortress, both of which are revealed to be inadequate defenses against the primordial power of the deep.
