Morgan trails after Serena, waving distractedly at Lizzie as she chats animatedly with “Gorgeous Josh.” Morgan finally finds Serena alone at the stern of the boat. Morgan approaches cautiously, telling Serena that she does not think she did anything wrong. Serena snaps back that Morgan shut herself off, never communicating what was going on with her, and Serena feels hurt and excluded. She thought she and Morgan were closer than this.
Morgan tries to defend herself, saying it is up to her when she tells people private things, but she also admits she understands why Serena is hurt. Morgan starts to argue that Serena does not know what it is like, and Serena immediately interjects that she cannot know because Morgan never talks about it. She begins to tell Serena about Keltie and her secret identity as a selkie.
Meanwhile, Keltie enthusiastically approaches the boat’s captain, striking up a cheerful conversation. Keltie asks if she can steer, admitting the crowded, noisy birthday party is not really her “scene.” Amused, the captain agrees and warns her to keep the boat on course. When he steps away to use the bathroom, Keltie excitedly takes the wheel, planning to shipwreck the boat.
Back with Morgan and Serena, Morgan continues describing Keltie’s world, explaining the seals, the rookery, and why Keltie is so determined to protect them. Serena listens in disbelief as the pieces come together. She turns away. Serena finally tells Morgan that, if this matters so deeply to her, she will talk to her parents about changing the boat’s route so the seals are not disturbed. However, Serena wishes that Morgan had talked to her reasonably instead of making up a story. Serena sits on the boat railing, emotional and conflicted, and tells Morgan to tell Keltie that she has agreed to talk to her parents.
Morgan hesitates but then goes to find Keltie. She begins telling her she spoke to Serena, but before she can finish, Keltie grabs her hand and insists Morgan come with her. Keltie leads her to the center of the boat and asks her to hold onto the railing. She tries to explain something urgent, but Morgan interrupts, excitedly announcing she convinced Serena to reroute the boat. Keltie freezes, horrified. She blurts out that she may have accidentally set the boat on a collision course with the reef. Morgan yells that this is a disaster, and Keltie sprints toward the controls, determined to fix her mistake.
Meanwhile, Lizzie finds Morgan and gushes about her time with Gorgeous Josh, but her excitement fades when she sees Morgan’s panicked expression. Morgan urgently tells her to hold onto the railing. The images shift to show the boat cutting across the water while seals swim beneath it. The captain confronts Keltie, asking whether she touched anything. Keltie, guilty and frantic, admits she did. She pushes the captain aside and grabs the wheel, turning sharply. The sudden movement sends tables crashing and nearly throws guests off balance. Morgan grabs Lizzie to keep her from falling as the boat lurches violently. For a moment, everything tilts, then stabilizes. However, the images show Serena slipping from her perch on the railing and falling into the sea.
Keltie collapses over the wheel in relief once the crisis is averted. The captain, furious, declares her permanently banned from the boat when they dock. Keltie finds Morgan and Lizzie and assures them everything is okay now. They laugh in shaky relief.
The scene shifts to Serena, alone in the water, desperately swimming after the boat and calling for help.
Back aboard, the DJ announces the birthday celebration, and everyone sings while Lizzie and Jules bring out the cake. Morgan and Keltie cling to each other, sharing a quiet moment of relief. Morgan even allows Keltie to cuddle her in public.
People start calling out for Serena. Morgan looks up and realizes, with horror, that Serena is not in her spot on the railing. She tells Keltie that Serena had been sitting there earlier. Keltie listens to the seals and tells Morgan grimly that they say Serena fell.
Panicked, Morgan runs to the top deck and throws a life buoy into the water. Serena reaches for it, but a wave pulls her under again. Keltie tells Morgan that she has to save Serena. Morgan protests as Keltie can barely swim in her human form. Keltie insists the only way is to use her seal-skin. Morgan tears up, knowing what that means. If Keltie puts on her seal-skin, she will not be able to return to human form. Keltie holds her hands and says she has to fix this because the accident was her fault. Morgan whispers that they had plans. Keltie gently reminds her that sometimes plans must change.
With a trembling hand, Morgan gives Keltie the seal-skin and tells her she has to come right back. They share a brief, emotional kiss before Keltie wraps the skin around her shoulders and leaps into the water. The moment she breaks the surface, the skin ripples across her, and she transforms fully into a seal. She sweeps through the water, searching desperately until she finds Serena sinking below the waves.
Keltie approaches Serena, who stares in shock and fear at the seal swimming toward her. Keltie moves the skin slightly away from her face, revealing her human features. Serena’s eyes widen in recognition. Keltie gently grips Serena’s wrist in her mouth and pulls her upward. Serena finally reaches the life buoy and holds on.
As the partygoers gather at the stern, the captain, Jules, and Lizzie pull Serena in with the rope attached to the buoy. Morgan, trembling, stands apart from the crowd, her eyes locked on the water. She watches the captain haul Serena, soaked, exhausted, but alive, onto the deck. Morgan collapses to the floor, crying in relief and heartbreak. Below, Keltie rises to the surface. She pulls aside the seal-skin just enough to show her human face again. Morgan leans over the railing and begs her to come back to shore, reaching toward her. Keltie apologizes and looks down at her hand, now entirely covered in the seal-skin. Tearfully, she tells Morgan she must remain in the sea for seven years.
Morgan promises she will wait, but Keltie shakes her head. She tells Morgan to follow her plans, to live more, do more, become more, and that in seven years they will meet again and share their adventures. They hug and kiss through tears. Then Keltie’s face melts into seawater as she slips entirely into her seal form. Morgan watches her disappear beneath the waves.
The boat returns to the dock. Guests stand quietly, subdued after the chaos. Jules, Lizzie, and Serena sit together until Serena gets up to find Morgan. She discovers Morgan slumped at the stern, still staring out at the water. Serena looks at the teeth marks on her arm and tells Morgan she knows now that she was not lying. Morgan admits she herself was not sure she fully believed everything until tonight. Serena says Keltie saved her life and asks quietly if she is gone. Morgan nods, apologizing again. Serena helps her up and tells her she wants to go home to watch a bad movie and eat too much birthday cake with her best friends. Morgan agrees.
The narrative shifts to a beach montage. Morgan looks both happy and wistful as she plays in the surf with Min and Aiden. She explains in narration that the seals are safe now and that the town has grown used to the boat. She works at the kayak rental place, blushes when a cute girl notices her, and calls her dad.
Later, Morgan rides her bike home and stops on a hill overlooking the sea. Her neighbors, Earl and Val, join her. They comment that it is a good day to look for seals. Morgan asks if they knew about Keltie. Earl nods, telling her there have always been selkies on the island. Morgan admits she cannot talk to anyone about it because it sounds too unbelievable. Val gently tells her that a selkie’s love is special.
Morgan says that Keltie wanted her to be “more alive,” and Val tells her Keltie would want her to live fully, not stand at the cliffs waiting. Morgan asks how they know so much about selkies. Earl removes his glasses, revealing bright, dark eyes just like Keltie’s. He and Val smile and say they are very familiar with selkies. Together, the three of them watch the seals moving through the water.
The final section of the novel brings the story to its emotional climax and sets the stage for the characters’ future growth. While the narrative resolves many of the conflicts that have been building, it does not offer an entirely happy ending. Instead, it presents a layered resolution that emphasizes personal responsibility, honesty, and transformation. The section highlights how Morgan and Keltie must each confront the consequences of their actions and choices, as their decisions ripple outward into their friendships, families, and the larger community.
One of the most important emotional threads in this section is Morgan’s confrontation with Serena. Their fight exposes the damage that silence has caused in their friendship. Serena expresses her hurt directly: When Morgan protests that she “didn’t do anything,” Serena turns this defense back against her, pointing out that Morgan’s inaction is the problem (187). She shut Serena out completely, along with the rest of the friend group. For Serena, Morgan’s secrecy feels like rejection, especially since Morgan shared the truth with “some random girl none of us has ever met before” rather than with her closest friends (188). Morgan tries to defend herself, explaining she “didn’t want to be different” and that no one would understand (189-90). However, Serena rejects this excuse, pointing out that she cannot understand Morgan’s experiences if Morgan never talks about them. Their argument shows the core problem Morgan has faced all along: She protects herself by shutting others out, even people who love her. When Serena later says, “I wish you would just talk to me like a normal person instead of telling me weird lies,” it highlights how secrecy has undermined Morgan’s relationships, making it hard for people to believe her even when she is being honest (196). This difficult conversation forces Morgan to embrace a degree of vulnerability that she has heretofore avoided, and the moment marks the beginning of her emotional transformation.
Keltie’s arc in this section mirrors Morgan’s, emphasizing responsibility and change. When Serena falls overboard, Keltie faces her own turning point. She knows she cannot save Serena in human form, and she admits, “I need my seal-skin” (215). Morgan immediately realizes what this means: once Keltie puts it on, she cannot return. Keltie, however, accepts full responsibility, “It’s my fault. I must fix this,” showing a level of maturity she did not have earlier in the story (215). Her decision to use the seal-skin, knowing she will be forced back into the ocean for 7 years, marks a critical moment of growth. It proves that Keltie is no longer acting from impulse or excitement; she is thinking about consequences and about the safety of others. The moment also serves as a rebuttal to traditional selkie tales in which the selkie’s male lover keeps prevents her from returning to the sea. In this version, Morgan respects Keltie’s autonomy without question. When Keltie asks for the skin back, Morgan immediately gives it to her despite knowing that it will mean losing the girl she loves.
When Keltie uses the seal-skin and shifts into her true form, her transformation reflects Morgan’s internal change as well, highlighting the theme of Change as a Catalyst for Personal Growth. While Keltie must return to the sea, Morgan must move out of the emotional “boxes” she has kept herself in. Their separation scene shows both girls choosing honesty and growth over the comfort of staying the same. When Morgan insists she will wait seven years, Keltie refuses. “Don’t you dare,” and pushes Morgan toward a fuller life instead of encouraging her to wait (227). Keltie urges her, “You have plans. Go do them. Do more!” (228), emphasizing that Morgan’s story cannot stop because their relationship must pause. Their farewell is tender but also signals a shift toward independence.
This moment also ties directly into the theme of The Burdens and Consequences of Secrets. Throughout the novel, secrecy weighs heavily on both girls, creating misunderstanding, guilt, and isolation. In this final section, honesty lifts these burdens. Morgan finally tells the truth to Serena. Keltie is honest about what she wants from Morgan. Even Serena, once rescued, acknowledges what she saw and admits, “You weren’t lying about her” (236). Morgan, in turn, admits she herself “wasn’t sure if [she] believed it either” until everything unfolded (236-37). Their reconciliation is simple and warm: Serena wants nothing more than to “hang out with my best friends, watch a bad movie, and eat too much birthday cake,” reminding Morgan that her friendships are still solid underneath the hurt (238).
Morgan’s transformation continues after the rescue as she navigates life without Keltie. In her narration, she notes that “the seals were safe” and that the community eventually accepted the changed boat route, showing that even this tradition-bound small town can undergo transformation (240). She reflects that even confusing or messy situations can “become normal,” showing that she is beginning to adapt to change rather than resist it (241). Her growth also appears in her interactions with her family and her new job at the kayak rental shop. She blushes at a cute girl, talks openly with her dad, and begins to imagine a broader, more open future for herself, all signs of her expanding identity.
The final conversation with Earl and Val brings closure to the selkie storyline while reassuring Morgan that her experiences were real and meaningful. When Earl tells her, “There have always been selkies here,” he validates both her relationship and her grief (243). Morgan confesses that it is “hard to really talk about to anyone,” because explaining the situation feels impossible (244). Val responds with wisdom: “The love of a selkie is something special […] sudden and powerful […] and in its wake, things are changed forever” (244-45). This affirmation helps Morgan understand that Keltie’s presence in her life changed her for the better. Keltie taught her to be “more alive,” to live all parts of her life rather than hide. Earl and Val encourage her to keep moving forward rather than “wait at cliffs,” reinforcing the idea that love can shape her future without trapping her in the past.
This section ultimately shows each character stepping into a more honest, open version of themselves. Morgan speaks openly, repairs friendships, and stops hiding pieces of her identity. Keltie accepts responsibility and embraces her true form. Serena shows empathy and forgiveness. Even the community adapts. While the story ends with separation rather than a traditional happy conclusion, the emotional resolution is hopeful. Morgan moves into a future shaped not by fear or secrecy but by growth, truth, and the promise of meeting again after seven years, stronger, more alive, and more fully herself.
