Sophie Honeywell arrives on Scribbly Gum Island and settles into the inherited house despite some plumbing issues. Her lawyer Ian, who missed the ferry, stays overnight, but Sophie makes it clear she is not interested in him romantically. Soon after, Sophie meets Zeke, an island resident, who takes her to significant locations tied to the mystery of Alice and Jack Munro, including Swampy's Cove where their boat washed ashore years ago.

Sophie and Veronika continue their investigation into Alice Munro's disappearance. They discover that Alice worked at Finch and Son's department store as a shop girl, evidenced by several dresses with model gown labels found in Alice's closet. This leads them to track down Jan, a former colleague of Alice, who reveals that Alice's manager at Finch and Sons was known as Breadboard Man. Breadboard Man was murdered with a breadboard at his kitchen table two days before Christmas. Jan explains that this manager had introduced his new fiancée at work and was involved in a dangerous situation with Alice, raising questions about what really happened to Alice and Jack and why island residents have conflicting stories.

Meanwhile, Sophie rejects Ian's romantic advances, and her connection with Zeke deepens as they share moments that hint at growing attraction. Sophie allows herself to be vulnerable, and their relationship begins to develop amid the unfolding mystery.

Grace, who is struggling with motherhood, plans to take her baby to the mainland. While waiting for the ferry, she hallucinates that people around her are telling her the baby is not hers and that she should give him away. Disturbed, Grace returns to the Munro house, places her baby in the crib, and lies down on the bed. When Enigma, Grace's mother, arrives with a tour group, Grace quickly picks up her baby and leaves, masking her distress.

At dinner, Sophie offers Grace some dessert, but Grace has an allergic reaction due to nuts in the food. As her throat closes up, Grace imagines herself in the sea with Alice calling her, reflecting her deep depression and suicidal thoughts. Sophie panics, and Callum administers an EpiPen. While Grace recovers, she watches Sophie holding the baby and standing with Callum, perceiving them as a perfect family and doubting her own fitness as a mother.

During their own dinner, Enigma asks Rose if she thinks she is a terrible mother. Rose tells her to eat, implying that Enigma does feel like a bad mother. Enigma admits she believes she has the right to be terrible because she was abandoned, but Rose reminds her that Connie, Enigma's mother, was a fantastic mom to her.

The episode ends with Sophie and Veronika uncovering more about Alice's life, including the abusive power Breadboard Man wielded over Alice and others, which may have led to Alice's departure from the island. Grace's mental health continues to deteriorate under the pressure of motherhood and her fraught relationship with Enigma, setting up further emotional and narrative tension.

At the end of The Last Anniversary, Season 1, Episode 3, a DNA test reveals the true parentage of the character Enigma, providing a crucial answer to one of the island's mysteries. However, this revelation causes Rose to withdraw emotionally, retreating further into herself.

Expanding on the ending scene by scene:

The episode culminates with the results of a DNA test that Sophie and the islanders have been anxiously awaiting. This test confirms Enigma's biological parentage, resolving a long-standing question that has been central to the island's tangled family secrets. The moment is charged with anticipation as the characters gather to hear the news.

When the results are announced, Enigma's identity is clarified, which is a pivotal moment for her character and the community. Despite the clarity this brings, the emotional impact is complex. Rose, who has been closely connected to Enigma and deeply involved in the unfolding mysteries, reacts by withdrawing emotionally. She becomes more reserved and distant, indicating that the truth, while illuminating, also brings pain or discomfort.

The episode closes with Rose's retreat into herself, highlighting the emotional cost of uncovering hidden truths. Sophie, who inherited the house and is central to the unfolding drama, witnesses this change, underscoring the ongoing tension and unresolved emotional conflicts on Scribbly Gum Island.

Thus, the ending of Episode 3 balances revelation with emotional complexity, showing that answers can deepen personal struggles rather than simply resolve them. The fates of the main characters at this point are:

• Enigma: Gains clarity about her origins but faces the consequences of this truth.
• Rose: Becomes emotionally withdrawn, signaling internal conflict.
• Sophie: Continues to navigate the island's mysteries and the impact of the revelations on its inhabitants.

This ending sets the stage for further exploration of family secrets and personal dynamics in the episodes to come.

The episode's conclusion focuses on deepening the character relationships and the unfolding mystery rather than including a post-credit teaser or extra scene.

Alice Munro worked as a shop girl at Finch and Son's department store, where she had a difficult relationship with her manager known as Breadboard Man. This man was murdered with a breadboard at his kitchen table two days before Christmas. Alice's connection to him and the circumstances around his death raise questions about what really happened to Alice and Jack Munro, as the islanders have conflicting stories about these events.

In Episode 3, Sophie rejects one suitor but begins to explore a connection with a new island resident named Zeke. This marks a shift in her personal life as she settles into island life and navigates new relationships.

Grace struggles deeply with motherhood, experiencing post-partum depression and hallucinations that cause her to doubt her fitness as a mother. She also faces emotional abuse and pressure from her own mother, Enigma, who is harsh and critical. Grace's mental state deteriorates to the point of a severe allergic reaction and a near-suicidal episode, highlighting her fragile condition.

Sophie and Veronika uncover significant new information about Alice Munro's past, including her secret job and the troubling relationship with her boss, Breadboard Man. This discovery sheds light on the Baby Munro case and suggests that Alice's disappearance and the mystery surrounding the family are tied to darker events on the island.
