Summary

After the ship sinks, transformed mermaids Mary and Eliza find Bridie, Sarah, and Annie trapped in an air bubble beneath the hull. The women initially recoil in fear, but Mary and Eliza sing their old song to prove their identity. Bridie recognises them and trusts them. They swim the survivors to the surface, build a raft from wreckage, and gather supplies. On the raft, the women bid farewell to those lost. Mary and Eliza share a deep reconciliation: Eliza confesses she once pretended to be afraid to stay with their father, and Mary apologises for not believing her about their mother. Mary decides she will not return to land; she embraces the sea as her true home. The group parts ways—the human women plan to evade recapture, while Mary and Eliza vow to protect all the vulnerable girls who will come to their cave.

Character Development

Mary
Mary fully accepts her merrow form and feels a profound aesthetic and spiritual belonging in the underwater world. She forgives herself and Eliza for past fears. Her purpose shifts from the conventional wish for a husband and child to a fierce, protective motherhood that transcends biology—she will become a guardian for every girl who arrives at the cave.

Eliza
Eliza is now confident and certain. She reveals that she had long dreamed of this moment and that she consciously deceived Mary to spare her guilt over their mother’s departure. Her sincerity deepens their bond.

Bridie
Bridie overcomes her first terror and demonstrates loyalty and pragmatism. She refuses to pray to the Christian God, instead honouring the “old gods” and leading the farewell to the dead. She encourages the group to evade capture by hiding rather than surrendering to the female factory.

Sarah and Annie
Sarah’s maternal care remains central (soothing Annie, gripping Mary’s hands). Annie shows resilience despite her fear, saying a small prayer for the dead. Both cling to the hope that Bridie’s plan will keep them free.

Themes, Symbols, or Motifs

Transformation and Identity
Mary’s physical change mirrors her internal acceptance of her true nature. The song (“You should have known me before”) becomes a proof of identity that transcends appearance.
The Sea as Freedom
The underwater world (“tír fo thuinn”) is depicted as a female realm of beauty and safety, contrasting with the violence of the colonial ship and the oppressive land. Mary chooses this world over her father’s land.
Sisterly Reconciliation
The chapter resolves the long-standing rift between Mary and Eliza. Their apology and understanding echo the novel’s larger theme of healing across generations.
Colonial Violence and Resistance
Mary explicitly rejects the English who “split open” the land. The women’s decision to hide rather than submit to the female factory embodies quiet defiance.
Non-Biological Motherhood
Mary redefines motherhood as protection and vengeance for all vulnerable girls, not as bearing children. This inverts the earlier grief of the mermaid who had to choose between the sea and her child.

Why This Chapter Matters

This chapter is the emotional and thematic climax of Mary’s arc. It resolves the sisterly conflict that has simmered since their arrest and fully activates Mary’s role as a protector of women. The rescue underscores the novel’s emphasis on female solidarity across the human-mermaid divide. Symbolically, the farewell to the land and the embrace of the sea marks a definitive break from patriarchal and colonial structures. The chapter also sets up the remaining narrative: Mary and Eliza will become guardians of the cave, while the human women must survive on their own terms.

Study Questions and Answers

1. Why does Bridie initially mistake Mary and Eliza for monsters, and what makes her change her mind?
Answer: The women are terrified by the scaled, finned bodies of the merrows, which appear monstrous in the dim air bubble. Bridie changes her mind when Mary and Eliza sing the song they used to share in the convict hold—“You should have known me before, I sang you to sleep.” The familiar melody and words prove that the creatures are still the women they knew.

2. What does Mary mean when she says she will “mother all the girls who came to this place”? How is this different from her earlier idea of motherhood?
Answer: Earlier, Mary believed her purpose was to marry a man and bear a child. Now she redefines motherhood as a protective, communal role: she and Eliza will shield every vulnerable girl who arrives at the cave, offering safety and seeking vengeance when needed. This shift moves motherhood from a biological destiny to a chosen, political act of care.

3. How does the scene on the raft function as a farewell to both the dead and to the sisters’ former lives?
Answer: The women pray for the souls of the drowned, using the Irish blessing “Slán abhaile” (safe home). Sarah, Bridie, and Annie must let go of the past and plan a new life of hiding. Simultaneously, Mary and Eliza must say goodbye to their human friends and to any possibility of returning to land. The raft is a liminal space between two worlds, marking a final separation.
