At the Airbnb, Richie sits outside near the pool and watches Marco and Emily play with their daughter Ava in the water. He reflects on how his and his friends’ lives have changed and how it feels to be back together. He and Sasha talk about who will be coming for the weekend. When he reveals that Mitch and Nina are coming, Sasha launches into a rant about Nina’s work for an e-cigarette company. Richie, meanwhile, studies his friend Rami across the lawn. Richie and Rami met through AA right after Richie got sober. After Richie’s first meeting, he and Rami went out, and Richie opened up about his life before getting sober. Now, Richie studies his surroundings and feels a sense of peace.

Mia changes into her bathing suit at the house, noticing her friends outside at the pool. She thinks about how Marco has and has not changed. Downstairs in the kitchen, she chats with Adam before heading out to the pool. Studying Marco, she realizes she feels differently toward him in light of her relationship with Lev. 

The group has a conversation about work and politics, which is quickly derailed by Mia’s friends’ children. She reflects on how much Sasha has changed since having Ethan and how hard it has been for them to relate to each other now. An argument ensues between Emily and Marco about who is going to care for a screaming Ava. Marco huffily takes the baby inside while Emily settles down on the edge of the pool with Mia and a glass of wine.

Sasha finds Adam cooking in the kitchen. Instead of offering to help, she asks him to amend his recipe and privately recalls when they used to live together. She also thinks about how uncomfortable she’s felt in her body since giving birth. They chat about Theo, who went bankrupt after losing his real estate job six months prior. Sasha vents about how depressed Theo has been and how frustrated she is that he hasn’t found new work to support their family.

Afterward, Sasha wanders through the house, finding Mitch in the den. He pulls her to him and kisses her. The two have been having an affair for some months, but Sasha worries about being intimate here. Sasha doesn’t like Mitch but likes the secrecy of their relationship. She lets him touch her until she hears Marco’s voice upstairs and pushes him away.

In the bedroom alone, Marco struggles to calm Ava down. He ruminates on how difficult it’s been to become a father and to make Emily happy. He rocks Ava near the window, describing each of his friends to her until she calms down. Meanwhile, he recalls Mia and Lev’s visit to DC the year prior and reflects on how much he dislikes Lev. Lost in thought, Marco suddenly realizes Ava has fallen asleep.

Downstairs, Marco runs into Mia. When she asks about parenthood, a sweating Marco admits how tired he is and asks if Mia wants children. She insists she is too selfish to be a mother, and Lev doesn’t want a family. Marco suggests that she and Lev aren’t right for each other, upsetting Mia.

Richie plays bocce with his friends. Everyone exclaims about how good he is. Richie privately feels irritated that it’s easier to play when he isn’t drinking. Sometimes he hates how much better his life is sober. He reflects on the work he’s done to change and the difficulty of each one of the 12 Steps. 

He remembers confronting and apologizing to Adam not long ago. They took a walk, and after making amends, Adam suggested renting an Airbnb for Richie’s birthday. Now, Richie’s friends suggest he play bocce blindfolded to give them an advantage. Richie throws the ball with Nina’s scarf over his eyes, accidentally hitting Lev in the eye. Rami runs to the kitchen for ice.

Over dinner, a swollen-faced Lev tells the table a story of meeting Elton John. Only Nina is interested. Mia feigns interest because she knows Lev is upset about the bocce ball incident. While tending to his injury earlier, she found herself regretting bringing Lev, as she doesn’t feel like herself around her friends with Lev there. The sound of Ethan crying from the other room interrupts the conversation.

Watching Sasha excuse herself from the table, Mia recalls getting pregnant six months ago. She waited to tell Lev and her friends, unsure what she wanted to do. The longer she waited, the happier she felt to have this secret. However, she lost the pregnancy 10 weeks in, telling the doctor she’d planned to have an abortion anyway. When she finally told Lev, she was surprised to find herself bursting into tears. Lev reminded her, “Serious people don’t have children” (213). Overwhelmed at remembering this now, Mia excuses herself from the table to get the cake.

After dinner, Richie and Adam suggest that they all play a game of Celebrity. Marco and Mia are on the same team and get the most points. Meanwhile, Richie is distracted watching Adam and Rami sit close together, their knees intermittently bumping. Between rounds of the game, Richie steps outside for a smoke and finds Emily sitting with her face in her hands. He realizes how much everyone’s lives have changed while he was busy getting sober.

Nina urges the group to restart the game, meanwhile reciting positivity mantras to herself. She was devastated when she heard about Richie’s party online and hadn’t been invited. She called her mother, who encouraged her to invite herself. After she texted Richie, he agreed she could join. Now, she feels upset and ignored by everyone. 

She wanders off in search of the bathroom, accidentally opening a bedroom door where Sasha and Mitch are having sex. They both curse Nina, and Mitch races out. Afterward, Sasha opens up to Nina about how hard it’s been to become a mother and the escape her and Mitch’s affair has offered her. Nina is sympathetic, delighted that Sasha seems to need her. She promises to keep the affair a secret.
