However, the relationship is complex: Gruner treats her as property while Aneris maintains a stubborn sense of kinship that eventually allows her to choose friendship with Friend over obedience to Gruner.

Gruner refuses to let Friend signal the passing ship because he has no desire to leave the island. After years of isolation, Gruner has become inseparable from his role as lighthouse keeper and from Aneris. He attacks Friend during the flare struggle, explaining that he will not allow anyone to disrupt his established life on the island, even if it means keeping another person trapped there against their will.

Foreshadowing: This refusal reveals Gruner's deep-seated commitment to his isolated existence, foreshadowing his fatal decision to walk out of the lighthouse.

Gruner tells the newcomer that the previous weather observer died of typhus and that there is no body to bury. However, the predecessor's diary filled with sketches of strange sea creatures suggests a darker truth, the previous observer likely encountered the creatures and may have been killed during one of the nightly attacks. The typhus story appears to be a cover-up, mirroring the lie Friend tells at the end of the movie.

Foreshadowing: The diary's existence hints that the creatures have been attacking long before Gruner and the newcomer arrived.

Gruner walks out of the lighthouse after dropping his axe because he experiences a moment of emotional collapse. When Friend pleads for him to remember love, Gruner seemingly succumbs to the weight of his isolation and cruelty. He exits the lighthouse voluntarily, only to be immediately surrounded and killed by the waiting mob of sea creatures. This fatal decision represents both a breakdown of his survivalist mentality and a tragic failure to adapt to the changing dynamic with Aneris and Friend.

Foreshadowing: Gruner's refusal to accept peace with the creatures and his command for Aneris to return seals his fate.

The sea creatures appear to be attempting to reclaim Aneris, whom they lost when Gruner freed her from his net. Friend believes the nightly attacks are efforts by the sea to reclaim their own, and Aneris's mournful wail from the water after the explosion suggests a connection to her kind. The creatures are intelligent, organized, and persistent, they climb the lighthouse, coordinate assaults, and mourn their dead, indicating they possess civilization and social structure beyond simple animal behavior.

Foreshadowing: The revelation that Aneris leads Friend to a rowing boat hinting at escape suggests the creatures want her return above all else.

Friend lies about the weather observer dying of typhus to maintain the same deception he was told upon arriving on the island. By echoing Gruner's original lie, Friend perpetuates the cycle of concealment that has defined the island's history. This ending suggests Friend may be choosing to stay on the island indefinitely, either because he has become tied to Aneris or because he has accepted the isolation Gruner once embraced. The lie also protects whatever truth exists between humans and the sea creatures.

Foreshadowing: This lie mirrors the very first conversation Friend has with Gruner about the previous observer's death.

Aneris leaves into the sea at the end because Gruner's death removes the master she was bound to, and the temporary truce established by Friend has run its course. After watching from a distance as the replacement ship arrives, Aneris takes one final leap into the ocean, swimming away from the island. This departure represents both a release from her captivity and a return to her own kind, leaving Friend alone but having achieved a fragile understanding with the creatures.

Foreshadowing: Her mournful wail from the sea earlier signaled her conflicted loyalty between Gruner and Friend.

Friend names Aneris as a way of acknowledging her individuality and humanity, rejecting Gruner's view of her as mere property. This act of naming represents Friend's growing attachment and his belief that the creatures possess civilization and emotion. By naming her, Friend establishes a personal connection that contrasts sharply with Gruner's utilitarian relationship with the creature. The name becomes a symbol of his empathy and their developing bond.
