Courtney wakes early with her face aching from Wyatt’s assault. She recalls that Nolan used to sleepwalk, wondering if the condition is hereditary. When Greta Dahl knocks, Courtney answers to avoid being alone with Wyatt. Greta gives her the key to Emily and Nolan’s cottage, now released by police.

Greta notices Courtney’s bruise. Courtney lies about running into a doorframe, but Greta skeptically remarks that doorframes do not have fingers. When Courtney asks about a resort employee, Greta correctly guesses she means Daniel Clarke, whom she hired as a favor to his late mother. She describes him as unreliable but mostly harmless.

Greta bluntly tells Courtney her niece is dead, then clarifies that she does not know this for sure but thinks it is safe to assume. After Greta leaves, Courtney opens Elliott’s fishing cooler, finding it empty and clean. Elliott appears and claims he threw the fish in the dumpster. Courtney feels suspicious, and her thoughts turn to the photos of Reese on his iPad.

Reese examines her reflection in the bathroom, thinking about Daniel. She studies her body, including the minimalist tattoo Skylar’s cousin gave her despite both being underage. When Emily tries the locked door, Reese screams at her.

At the pool, Courtney compliments Reese’s pink sweatshirt until Emily mentions Reese mutilated it by cutting the neckline. Reese feels judged and is angry until she sees Daniel watching her intently from across the pool.

Emily notices Daniel and questions Reese about him. Daniel signals Reese to follow. Behind the pool house, he complains about Emily’s control, kisses Reese, and asks her to meet him on the pier that night. When Reese says she will try, Daniel acts wounded and pressures her until she agrees to come.

Elliott returns after failing to find other lodging. Detective Evans arrives with updates: Police found a knife in Emily and Nolan’s cottage with blood that does not belong to either victim, plus two sets of unidentified fingerprints. The victims’ phones were recovered, but Reese’s phone remains missing. Evans requests elimination fingerprints from Courtney’s family.

Courtney feels increasingly confined in the small, musty cottage. She notices a fly dead in her coffee and feels physically ill. She takes the car keys and tells Elliott she is going to the store for groceries, though she is actually planning to go elsewhere.

Reese sends Wyatt $20 via Venmo to keep quiet and sneaks out to meet Daniel on the pier. They drink beer together, and Reese mentions the unmarked grave. Daniel gives Reese a gold beaded necklace and professes intense feelings, saying he thinks he could fall in love with her. Reese feels overwhelmed, having never had a boy interested in her before. They kiss until dawn, and Daniel walks Reese back to the cottage. She wonders if it was real or just a dream.

Courtney visits Sam and Joanna Matthews. When they notice her bruise, she explains it as Wyatt sleepwalking. Joanna recounts Kylie’s disappearance five years earlier. She admits briefly suspecting Sam but says surveillance footage proved his alibi. Joanna shows Courtney Kylie’s preserved bedroom and Sam’s shoebox of evidence, including Polaroid photographs of Kylie’s friend, Abby’s, house, where Kylie was last seen. Joanna mentions that Greta Dahl told her Kylie was dead. As Courtney leaves, she notices a family photograph showing Kylie wearing a beaded gold necklace. Something about the image seems vaguely familiar.

Emily notices the beaded necklace Daniel gave Reese and comments on the pattern. Reese defensively lies that it is Skylar’s. At the pool, Mae and Cass use Elliott’s iPad to take pictures of Reese. That night, Reese prepares to meet Daniel but finds Emily awake on the sofa after fighting with Nolan. Emily interrogates Reese about being awake and fully dressed at midnight. Reese claims she wanted water and fell asleep in her clothes. Emily notices perfume. Reese returns to the porch frustrated, wondering what Daniel will do when she does not appear.

Courtney searches online for Daniel Clarke’s address and drives to his dilapidated manufactured home on Moon Road. She approaches the house and finds the sliding glass door open. She enters, stunned by a rancid smell. The dark, cramped house contains dirty dishes and a silently playing television. Down a dim hallway, she finds a filthy bathroom and bedroom with expensive-looking jewelry on the dresser. Beneath the bed, she discovers Reese’s pink sweatshirt with blood on the sleeve. As she examines it, she hears someone arriving. Before she can escape, the front door bursts open, and she faces a gun barrel.

Reese successfully sneaks out and finds Daniel skipping rocks by the lake in a darker mood. When she apologizes for being late, Daniel says he will kill Emily if she keeps Reese from him. Reese dismisses it as exaggeration. Daniel’s mood softens and he leads Reese into the woods. He asks if she wants to be with him, and she agrees. They begin to have sex on the forest floor. Daniel is gentle and repeatedly asks if she is comfortable. Just as Reese confirms she is ready, Daniel freezes, hearing movement in the trees. Something approaches through the darkness.

Detective Evans responds to the trespassing call and confronts Courtney. She explains she found Reese’s bloody sweatshirt under the bed. Evans warns that illegally obtained evidence could be inadmissible and that such actions could impede the investigation. Outside, Evans notices Courtney’s bruise and gently asks whether Wyatt caused it. Courtney admits Wyatt hit her during a sleepwalking episode, saying he was having a nightmare about a kidnapper and lashed out in his sleep. Evans asks if she feels unsafe with Wyatt; though afraid, she insists it was an accident. Evans then questions Wyatt’s claim of sleeping through the attack after taking Benadryl for allergies, noting that police found no such medication in the cottage. Courtney realizes Daniel’s house sits across from where Kylie Matthews was last seen.

Elliott interrupts Reese and Daniel in the woods, catching Reese undressed. Daniel flees. As Reese scrambles to get dressed, Elliott says he will tell her parents. Without hesitation, Reese threatens to accuse Elliott of inappropriate touching if he tells anyone. Elliott goes pale, calling the accusation serious. Reese asks if he thinks she cares, making clear she will say whatever is necessary to silence him or ensure no one believes him.
