To dodge an awkward conversation, Rachel hides in the pantry while Tully tells Heather stories about Rachel’s rebellious teenage years, explaining that she abruptly stopped dating at 16. To change the subject, Rachel brings out engraved salad servers, a cherished gift from their mother, Pamela.

Heather reveals that she visited Pamela that morning because she wants to be part of the whole Aston family. The women move to the courtyard to eat. When Rachel goes back inside, she discovers that the salad servers have vanished.

Heather drinks wine with the sisters, despite promising Stephen that she would abstain from drinking. Darcy texts Rachel’s phone, and Tully and Heather seize it, sending flirtatious replies and accepting a date on Rachel’s behalf. Just then, Sonny calls Tully’s phone. As Heather reaches into Tully’s handbag to retrieve the phone, she finds the missing salad servers inside.

Based on what Tully revealed about Rachel’s adolescence and Rachel’s reaction to a story about a survivor of sexual assault, Heather suspects that Rachel was raped during her teenage years. She is surprised that no one else in the family has noticed what seems to be obvious to her. After Tully leaves, Heather asks to stay and continue drinking with Rachel.

Tully wakes with a severe hangover. Sonny is supportive, letting her sleep while he cares for their sons. Tully remembers the stolen items in her bag and moves them into her bedside table. Sonny tells her that their house is officially for sale. After comforting him, Tully vows to stop stealing.

When Sonny develops a headache, he asks for painkillers. Tully directs him to her bedside table, inadvertently causing Sonny to find the stolen items.

Rachel prepares for her date with Darcy but expects to cancel. She finishes a client’s wedding cake, then receives a message from Darcy that begins with the same casual greeting her attacker used when she was 16. This triggers a flashback to the rape.

Shaken, Rachel cancels the date, claiming illness. She turns to the finished wedding cake and compulsively eats handfuls, destroying her work.

Heather wakes at Stephen’s house hungover, with a bruised elbow. Stephen says she fell down the stairs while drunk. Heather recalls the sensation of being pulled by her ankle just before the fall, which contradicts Stephen’s account and unsettles her.

The narrative shifts forward to the wedding day. Police begin arriving at the chapel and question the wedding guests who are preparing to leave. The narrator feels uncomfortable when she is asked to provide her name, but eventually reveals her identity: She is Fiona Arthur.

Sonny confronts Tully with the stolen items. She confesses that she stole them and explains that shoplifting has long felt like a release for her anxiety. She admits that she has been shoplifting since she was 11, and she also lied to a previous counselor. Sonny identifies her behavior as kleptomania and tells her he feels he no longer knows her. Before Tully can respond, their son Miles erupts in a screaming tantrum.

Rachel hides at home, ashamed after consuming the top two layers of the wedding cake. Darcy arrives unexpectedly, offering to deliver the cake for her. When she lets him in, he sees the destroyed cake.

Darcy does not judge. He asks when the cake is due to be delivered and, seeing Rachel’s distress, calmly says he has an idea to fix the crisis.

Heather moves into Stephen’s house and tries to dismiss her suspicion about the fall. In a flashback, she recalls their connection deepening after she comforted him over moving Pamela into care. Heather and Stephen’s relationship did not become romantic until after Pamela moved into a care home. Although Heather is excited about the progression of her relationship with Stephen, alcohol continues to be a point of tension between the couple.

As Rachel goes to visit her mother, she thinks back to how Darcy resolved the crisis the previous day. He and Rachel bought supermarket cakes, redecorated them, and delivered a convincing replacement. Touched, Rachel agreed to go on a real date with him. When she arrives at the nursing home, Rachel asks Pamela about the money and the note bearing the name “Fiona Arthur.” Pamela is unresponsive about the money but becomes extremely distressed when Fiona is mentioned. She states that Stephen hurt Fiona badly.

Five days after Tully’s confession, Sonny remains distant, and their house is being photographed for sale. To get the boys out, Tully takes them to McDonald’s for the first time. Their son Miles has stopped talking in response to the family’s stress.

During the outing, Rachel calls, and their son Locky blurts out that they are selling the house. Rachel immediately invites them for dinner.

When Tully arrives at Rachel’s house, she confirms the family’s financial collapse. Rachel gives her the $97,000 in cash from their mother’s hot-water bottle. They examine the note with Fiona Arthur’s name, and Rachel relays Pamela’s accusation that Stephen hurt this woman.

Rachel notices Miles’s anxious tics, which mirror Tully’s childhood compulsions. Prompted by the parallel, Tully reveals her final secret: She has kleptomania. Rachel calmly accepts the confession.

Heather and Stephen spend an afternoon filling out a wedding planning survey. Later, dressing for dinner with Stephen’s friends, Heather chooses the navy dress she wore on their first date. Stephen initially compliments it, then asks her to change, saying he wants to keep the memories tied to that dress private. He suggests a black pantsuit instead. Heather finds the request controlling but agrees to change.
