Walking back to the lighthouse in the rain, Fen cannot stop thinking about Yen’s mutilated body and what it means that a human body can be treated with the same brutal indifference she has seen in dead animals. That thought turns into grief for her mother, Claire, as Fen imagines what Claire’s body might have looked like after death. Fen also keeps remembering Rowan’s injured body and the intimacy of helping wash, dress, and care for Rowan, which gives Fen an unexpected sense of tenderness and connection to her own emerging womanhood.

At the lighthouse, the family eats a simple meal while the storm batters the building. Fen notices Dominic watching Rowan closely and recognizes that Rowan’s presence unsettles him because she brings change he cannot control. After dinner, Dominic retreats to work upstairs, Orly and Raff occupy themselves in the living room, and Fen and Rowan wash dishes. Fen asks whether Rowan is all right, but Rowan turns the concern back on Fen; when Fen starts crying over the dead sailor and what his family will be told, Rowan gently comforts her. When Fen asks why Rowan shaved her head, Rowan says she wanted to feel lighter, and Fen understands the impulse.

Later, Fen finds Raff hiding with a secretly charged phone and looking at a photo of himself with Alex. Overwhelmed, Raff shuts the phone off and smashes it against the wall. Fen tries to reach him by asking him to play music, knowing the violin once helped him, but Raff cannot manage it and leaves only saying that he will go to the bag. Wanting to stay busy, Fen makes drinks for everyone and brings tea to Dominic. Outside his room, she hears him speaking intimately to no one visible, then realizes he has been talking to Claire’s keepsakes stored in his wardrobe. After Dominic leaves to find Raff, Fen opens the wardrobe and studies the treasured objects he has hoarded from Claire’s family, including Claire’s annotated copy of Jane Eyre.

Fen sees the collection as proof that Dominic remains trapped in grief and believes the objects imprison Claire’s spirit as well. As part of her private effort to free them both, she steals Jane Eyre, taking only one item so Dominic will not notice immediately. That night, Fen insists Rowan take the bed while she sleeps on the couch downstairs. Sitting alone with the stolen book hidden against her back, Fen looks out the large window and becomes convinced she has seen someone pass outside. The sight terrifies her so completely that she rushes out into the rain and heads for the boathouse, guided by the green lights.
