A couple of days later, Sonya and Cleo visit Seth, Anna, and their newborn daughter, Fiona. They take turns holding the baby, and Sonya presents a welcome basket. The final gift is a double frame containing pastel portraits of the newborn and the new family, a joint project by Sonya and Cleo. The family is moved to tears.

During a quiet week in September, Sonya finishes sorting the ballroom and decides to redecorate the third-floor servants’ quarters, starting with Molly’s room. In Molly’s dresser, she finds the butterfly bottle and hair combs that they had previously given the spirit. Sonya retrieves furniture from the attic and purchases two small watercolor paintings from Cleo for the walls. Together, they finish decorating Molly’s room with a rug, flowers, and the new items. Clover plays Katy Perry’s “Daisies” in approval. They decorate two more empty servants’ rooms.

When Trey and Owen arrive with pizza, Sonya and Cleo show them the redecorated rooms. Sonya explains her vision for the ballroom and says she will hire help to move the heavy furniture.

On moving day, Sonya directs Trey, Owen, Cleo, and hired helpers John, Manny, and Bree using a color-coded sticky-note system. Dobbs remains quiet as they rearrange the ballroom according to Sonya’s detailed plan. Sonya convinces Bree and Manny to accept an Art Deco table as a housewarming gift.

When the furniture is in place, Trey grabs Sonya and waltzes with her to Clover’s playlist. Trey reveals he has a line on a vintage pinball machine and tells Sonya her plan to bring the house back to life is working. She’s bringing the heart back to the manor.

As Sonya does yoga in the gym, the instructor’s voice is replaced by Dobbs telling her she is weak and should drown herself in the sea. The on-screen image of the yoga instructor becomes grotesque, blood pouring down its face, with bones cracking as it contorts impossibly. Exercise bands hiss and writhe like snakes. The door slams shut, locking Sonya in darkness as the servants’ bell rings. She realizes she left her phone in the kitchen.

As she panics, a hand covers hers, and a voice whispers that Dobbs lies, that she is not alone, and that she is stronger than Dobbs. Upstairs, Clover blasts a warning song from Trey’s phone. He runs down the servants’ stairs and arrives just as the gym door opens, revealing a pale but triumphant Sonya. She shouts into the gym, taunting Dobbs. Feeling weak, she allows Trey to carry her upstairs. They meet Cleo, who was awakened by the music and the clanging of the Gold Room bell.

In the kitchen, Sonya recounts the attack. Encouraged by the spirit’s words, she had verbally assaulted Dobbs, mocking her and daring her to a physical fight. She remembers Clover and other spirits as they joined in mocking Dobbs. When the lights came on, Dobbs was gone, and Sonya had opened the door to find Trey. Trey kisses her passionately. Cleo hugs her fiercely. Clover plays Aretha Franklin’s “Respect.”

Sonya insists that Dobbs cannot kill her directly and must manipulate her into self-harm. She emphasizes that she will not comply. The group notes that Dobbs used the same insult with Sonya as she did on Owen, and concludes Dobbs is lashing out in fear, which makes her more dangerous. Cleo decides to cook a celebratory dinner to dispel the bad energy of Dobbs’s attack.

Later, over lunch, Trey expresses frustration, wanting to end the threat so he and Sonya can build a life together. Owen suggests that Sonya, as both a Poole and an outsider, is fated to find the solution. They agree that Dobbs is becoming darker and more desperate and fear she might break her own curse by sacrificing Sonya.

That afternoon, Sonya helps Cleo make bread and sauce for the celebration dinner. A Bundt pan appears on the counter, which they attribute to Molly. After launching the Bayside Lotions and Potions website, Sonya goes to the basement with her sketchpad to plan the game room. She enters the gym to confront her lingering fear. In the large storage room, she begins sketching. When Cleo comes down, Sonya says aloud that she wishes she could see the room as it once was.

The magic mirror materializes in front of Sonya. It feels like an invitation rather than a demand, and she steps through, reassuring a worried Cleo. She finds herself in the servants’ hall of the past, where she observes the staff at their duties and watches the head housekeeper, Hobson, introduce a new undermaid: 16-year-old Molly, who has just arrived from Ireland, proud and excited to work at Poole Manor. When Sonya tries to explore further, the mirror blocks her path and gently pulls her back to her own time.

Sonya returns to the basement. Cleo tells her she was only gone about two minutes, though it felt longer to Sonya. In the kitchen, she describes the servants’ hall and seeing Molly to Cleo as Clover plays David Bowie’s “Five Years,” indicating Molly worked at the manor for five years before dying. Sonya sketches Molly from memory. She and Cleo conclude that the mirror appeared because Sonya made a sincere wish to honor the past. They determine this new function of the mirror is a gift with limits, and she must not abuse it with frivolous requests.

That evening, Trey and Owen arrive with champagne. The dumbwaiter delivers a cake plate from Molly. After toasting Molly, Sonya tells them about her trip through the mirror and shows them her sketch of young Molly. She explains the mirror granted her wish because she intended to honor the manor. They speculate the mirror could be the way to retrieve the rings. Owen points out they will need Astrid’s portrait to complete the set of seven brides, and they agree to wait until all four of them are together before hanging the final portrait. They enjoy the celebration dinner.

Sonya leads them to the basement to show her game room plans. They search the basement and find nine original chairs from the servants’ hall, plus a sofa, and decide to have the sofa and two chairs reupholstered. Later, in bed, Sonya expresses hope that the spirits will be able to move on once the curse is broken.

As fall progresses, Dobbs’s manifestations are minor and petulant. Sonya contacts Maddy Black, an upholsterer recommended by Corrine. When Maddy examines the furniture, the Gold Room bell rings repeatedly, but Maddy is unfazed, recounting her own experiences working in haunted locations. In the kitchen, Sonya and Cleo choose a bold tapestry-like fabric for the chairs and purple for the sofa. Clover plays music, and Sonya explains about her grandmother.

After Maddy leaves, Sonya and Cleo admire the fall colors outside. The Gold Room window bursts open with a boom. A bolt of black lightning shoots from the window into the ground, shaking the earth and releasing a smell of sulfur. Sonya grips the protective stone in her pocket and observes that the lightning did not scorch the grass, reaffirming her belief that Dobbs’s power is limited. Cleo tells Sonya she has finished a secret project in her studio and invites her up for a reveal.
