Sloane sets an alarm for Sunday morning, but she doesn’t need it: She’s too excited to sleep. She puts on makeup and carefully selects an outfit. On the boat, Violet and Sloane drink sparkling apple cider before Jay explains to her the ins and outs of sailing. Jay learned how to sail at summer camp, but Jay doesn’t come from wealth. Sloane relates to his socioeconomic status. Jay and Sloane flirt, and Sloane admits to herself that she has more than a “crush” on him.

Violet receives her presents: Harper gives Violet a pink robe, Jay gives her a book, and Sloane gives her a necklace that’s similar to her “grandmother’s.” Violet gives Sloane a necklace with the same gold pendant that Violet has. Sloane feels extremely happy.

Violet and Sloane listen to Taylor Swift. Harper takes a nap, and Violet leaves to bring Jay a flash drive that he forgot. Alone, Sloane notices a copy of The Great Gatsby; inside there’s an inscription from Violet to Jay. She wonders if Violet and Jay read parts of the novel out loud to each other in bed. She thinks about Jay’s question about whether Violet has mentioned anything to Sloane about their marriage.

Yielding to “temptation,” Sloane goes upstairs. She lies down on Violet and Jay’s bed and imagines Jay next to her. She looks at Violet’s sexy underwear, and she puts on Violet’s robe. In the closet, she opens a box with Manolo Blahnik pumps and a grey flip phone. She can’t guess the password, but she gets a new text alert. The message is from DS. DS wants to know “which day.” Sloane wonders if DS is Danny and why Violet has a burner phone concealed in a shoe box.

In the bathroom, Sloane notes the generic dark chestnut brown hair dye. She uses Violet’s acne cream and goes through Violet’s makeup bag. Through the window, she sees Violet coming home. Hurriedly, Sloane smooths the pillow and bedsheets. She remembers to take off Violet’s robe. When Violet enters the brownstone, Sloane is on the bottom step. She tells Violet she was checking on Harper. On her way home, Sloane buys dark chestnut brown hair dye.

Sloane once dyed her hair red so it would look like Allison’s hair. She remembers Allison finding her in Allison’s closet. Sloane was in Allison’s clothes and looking at private photos. Sloane also used Allison’s perfume and brush. She liked “pretending” to be Allison. Allison was supposed to be in Boston, and Sloane was only supposed to come over to feed the cat.

Allison screamed at Sloane. Sloane tried to leave; she fell and grabbed a marble jewelry stand to stop her fall. Allison thought Sloane intended to use the marble stand to harm Allison, but Sloane had no intention of hurting her. Sloane felt like she was a member of Allison’s family.

On the first day at school after the incident, the director fired Sloane. Police charged her with stalking and menacing in the third degree. Sloane explained that she didn’t break in; Allison gave her a key. Her overworked court-appointed attorney got Sloane to plead guilty to stalking in the fourth degree—a misdemeanor. Sloane didn’t get jail time, but she had to obey a restraining order.

Back in the present, Sloane’s mother goes to bed, and Sloane dyes her hair brown. She tells herself that the situation is “different” because Violet is “different.” When Sloane wakes up, she realizes she did a shoddy job.

Violet pretends to admire Sloane’s new hair color before they both admit that it’s a “disaster.” With Harper on a playdate, Violet takes Sloane to her hairdresser, Nolan, who gives Sloane a hairstyle that looks like Violet’s. As Violet pays, a Rose & Honey business card falls from her purse. Sloane grows fearful. Violet says she hasn’t been to the spa. Violet invites Sloane back to her house. She wants to give Sloane some of her clothes.
