As the episode unfolds, Sandrine (played by Ludmilla Makowski) finds herself gazing intently at Zoe Dalton (portrayed by Sally Bretton), who is immersed in a tub of water, barely visible beneath its surface. With labored breaths, Sandrine curses under her breath before hauling Zoe out of the tub, where she gasps desperately for air. Sandrine cradles her, offering comfort as Zoe clings to her for support. Distressed, Sandrine sheds her jacket, revealing a deep scar marring her back. Zoe's curiosity piqued, she inquiries about the wound and offers an apology. Sandrine hastily reclaims her jacket, dismissing the matter with a curt, "It's none of your concern." Zoe persists, wondering aloud what might have transpired had she not discovered Sandrine, pleading with her to keep the incident confidential for fear it could unravel her marriage. Sandrine, lying down and sweeping her hair back, vows vengefully to make Zoe's life miserable, hinting darkly that murder crosses her mind.
Moments later, Chris (Kenny Doughty), Amber (Margot Pue), and Noah (Ripley Barden) arrive home, disrupting the tense atmosphere. Sandrine assumes a mask of concern for Zoe's well-being. Chris reassures her that she acted correctly, while Amber casts a wary glance at her as they ascend the stairs with Noah. With a forced smile, Sandrine closes the door behind them. Chris checks Zoe's blood pressure, probing how many pills she consumed. Zoe, taken aback, claims it was a mistake—a solitary sleeping pill. Amber and Noah pause in the hallway, drawing Chris's attention. He reassures them that Zoe will recover, amber questioning the rationale behind such an action. He emphasizes the importance of family unity, unaware Zoe overhears every word.
Elsewhere, Sandrine savors an apple, a knife glinting beside her, when a knock at the door interrupts. Zoe confesses her sense of failure, longing to regain her family's trust. She outlines her plans for Amber's upcoming birthday, pleading for Sandrine's assistance. Shortly thereafter, Zoe sketches a portrait of Amber, unaware Sandrine watches through the window before rushing to inform Chris. Chris downplays the incident as a harrowing accident, expressing a desire to believe Zoe's claim despite the striking similarity of prescription bottles—until he examines them closely and discovers they are vastly different.
As Zoe works diligently on Amber's tapestry, Chris approaches, urging her to join him in bed. She insists it's nearly complete. Upon finishing, Zoe delivers the tapestry to their bedroom, where she receives a flurry of messages from Amber's friends via Noah. Exhausted, she retires, only to awaken at 3 AM and lie back down. The next morning, Zoe proudly presents the completed tapestry to Sandrine, who studies it intently, relating to the struggle of earning others' affection. Zoe denies this motive, prompting Sandrine to reveal her father's role in inflicting her scars. Zoe reassures her that she is now an integral part of their family.
With a heavy heart, Sandrine takes the tapestry to the garden. Meanwhile, Zoe receives a stunning call from Dr. Vaughn (Vanessa Ifediora), informing her that she is five weeks pregnant—news that catches her completely off guard, as the embryo transfer hadn't occurred. In the garden, Sandrine douses the tapestry with lighter fluid, inhaling its acrid fumes, lost in dark contemplation.
Zoe approaches Chris after the party, seeking a private conversation. She senses his disapproval when she reveals her pregnancy, realizing he fears losing her due to her fragile state. Curiosity piqued, she inquires if he believes she deliberately ingested the sleeping pill. As they pass Amber's room, Sardine catches their eye, engrossed in her nail art. Noah offers Zoe a passing compliment, which she acknowledges before sinking into a chair, observing Amber warmly welcoming her friends. Her gaze falls upon Noah, clutching a lighter, prompting her to rush over, intending to confront him. Sardine, however, signals for Noah to remain silent.
Zoe then proceeds to greet her mother, Lydia (Lesley Molony), while Sardine whispers to Noah to use the lighter during Zoe's gift-giving moment to Amber. Zoe reassures Lydia that the sleeping pill incident was merely an unintended accident. George (David Suchet), ever-attentive, sends Zoe away with a tray laden with food, giving her a moment to reflect on her decision to pursue IVF without Chris, who views her as physically and mentally unstable. George captures a heartwarming photo of Zoe and Amber together.
Zoe informs Amber that the pizza is baking in the oven, only for Sandrine to stealthily ignite it after they depart. Moments later, Zoe attempts to salvage the burnt pizza amidst the blaring smoke alarm, to Amber's disappointment. Lydia's gentle inquiry about checking the oven temperature provokes Zoe's frustration, leading her to snap. Lydia suggests ordering more pizza, and Sandrine offers to take charge while Zoe prepares to change.
Later, Zoe opens her prescription bottle and notices Amber's acrylic nail on the sink, struggling to open the sleeping pill container. Alarmed, Zoe confronts Chris, asserting that someone swapped her pills. Sandrine steps in, suggesting it's time for the surprise. Chris concurs and summons Amber. Zoe concedes to Sandrine's earlier advice about earning love, as she unveils the tapestry, embracing her warmly. Chris joins in with hugs and kisses, while George captures another precious moment.
The pizza delivery arrives, and as Zoe takes a selfie with the tapestry, Sandrine discreetly sets it ablaze. George, looking up, spots the inferno unfolding. Chris springs into action, extinguishing the flames. Zoe, enraged, accuses Noah of lighting the fire, but Amber comes to his defense as he flees with Chris in pursuit. Sandrine tries to console Zoe, but Amber insists on a private conversation.
Accusations fly as Zoe blames Amber for switching her pills. Raye (Ebimie Anthony) gently leads Amber away, who confides that Zoe has changed since Sandrine's arrival. As Zoe reviews her photos, she spots Sandrine lurking behind the tapestry, prompting her to insist on searching Sandrine's room. Meanwhile, Zoe stands precariously on a chair, engaged in some task.
Sandrine warns Zoe that enough is enough, but Zoe demands she stop projecting her troubled past onto her. In a fit of anger, Sandrine kicks the chair, causing Zoe to tumble to the ground. In a moment of vulnerability, Zoe confesses her pregnancy and the urgent need to visit the hospital. Sandrine volunteers to take her, but Amber, having found a tag for Stephanie Lacroix in Sandrine's room, discovers through an online search that Sandrine is actually Stephanie, once entangled in larceny charges that were eventually dropped. Determined, Amber insists on confronting her, while Raye worries about her mother discovering Zoe's pregnancy.
At the hospital, Zoe clasps her hands in silent prayer, hoping with all her heart that her unborn child is safe. As she stands on the brink of her ultrasound, she extends her trembling hand, which Sandrine grasps firmly in return. The technician's voice, soft yet definitive, pierces the silence as she locates the baby's heartbeat. Zoe's shoulders sag in visible relief. Meanwhile, Sandrine excuses herself to the restroom to gather her composure.
As they depart the hospital, Zoe confides in Sandrine, her voice tinged with sorrow, about the loss of her firstborn at birth and the heart-wrenching decision to shield her from sight. Upon reaching their home, Zoe is met by Chris, who offers a heartfelt apology for the tapestry incident. Sandrine, upset by Zoe's revelation, dashes to her room, her mind replaying Zoe's words about her own child's untimely demise. In a fit of rage, she punches the mirror, shattering it into a thousand pieces.
Amber, determined to confront Sandrine, issues an ultimatum to Noah to stay away. She confronts Sandrine head-on, demanding to know her true identity, and then rushes to find Chris. Sandrine, cornered, responds with desperate force, knocking Amber unconscious with a wooden cutting board. As voices draw nearer, she hastily drags Amber's limp body into the laundry room, wipes away the telltale traces of blood from her head wound, and returns to conceal her crime. The cutting board lies abandoned on the floor, a silent witness to the violence.
George enters the scene, oblivious to the drama that has unfolded, and expresses his gratitude to Sandrine for saving him last week before leaving. Zoe, searching for Noah, picks up the cutting board and calls out his name. Meanwhile, Sandrine, in a panic, sends a text from Amber's phone to Raye, ignoring Zoe's desperate attempts to enter the locked laundry room. Donning a jacket, Sandrine drags Amber's body out the door, her mind racing.
Zoe apologizes to Noah, offering a tentative olive branch by suggesting he light the cake if they can reconcile. Outside, Sandrine struggles to drag Amber's body across the pathway, her efforts complicated by the weight and awkwardness of the task. Inside, Noah and Zoe bring out the cake, their spirits momentarily lifted.
Raye informs Chris and Zoe that Amber went to confront Sandrine and hasn't been seen since. She shows them a news article about Stephanie, adding to the atmosphere of tension and suspicion. Unbeknownst to them, Sandrine is hauling Amber's body away in a cart attached to a bicycle, navigating the dense woods. Chris, frustrated and anxious, takes out his emotions on Raye, but Zoe steps in to mediate. Using an app, Chris tracks Amber's phone to the woods, where Sandrine is riding the bike, dragging Amber closer to a creek.
Zoe and Chris, hearts pounding, continue to track Amber's phone signal through the woods. Miraculously, Amber regains consciousness, shoves Sandrine aside, and flees into the forest. Sandrine, relentless in her pursuit, gives chase. As Zoe and Chris emerge from their car on the road, Amber runs towards Chris, seeking refuge. Sandrine confronts Zoe, her voice breaking as she reveals the truth: she is Zoe's daughter. Chris, disbelief etched across his face, insists she is lying. Zoe, stunned, takes a step towards the car, her mind reeling with the revelations of the day.
