The final day of the families’ “Tahoe Games” concludes with Allie and Blake’s father, John Logan, defeating all competitors. Over the following week, many guests depart, leaving behind the younger generation and a few adults.

Blake spends time with Wyatt’s twin sister Gigi, the sharp-tongued Stella, and Ivy. One night on the boathouse roof, the boys pass around a joint while Blake stands near the edge, mindful of her fear of heights and remembering the dark moment earlier in the summer when she nearly jumped.

Beau approaches Blake and says he wants to kiss her, reminding her they nearly hooked up four years ago. Blake tells him she’s seeing someone, though she keeps their identity secret, and adds that even if she were single, it would ruin their friendship. The exchange makes her worry that her involvement with Wyatt could be similarly complicated.

During a morning workout, Garrett thanks Wyatt for watching over Blake, then reveals a surprise: He’s converting a storage room into a music studio for Wyatt’s mother—Hannah’s—birthday and enlists Wyatt’s help choosing equipment.

In the kitchen, Wyatt apologizes to Hannah for resenting her push to advance his music career. She explains she does it because he is talented and music helped her through a teenage trauma. Encouraged, Wyatt asks her to review tracks he’s written this summer, calling them his best work.

That night, Wyatt, Blake, and Gigi work on a jigsaw puzzle. Gigi deduces they’re together: Blake denies it, but Wyatt confirms the relationship and asks Gigi to keep it secret. Blake calls it a summer fling, which privately bothers Wyatt. On the dock, Gigi warns him that Blake will always be in his life and questions whether he knows what he’s doing. Wyatt admits he never does.

At the lake that week, Beau accidentally kicks Blake in the head while diving. She goes underwater and doesn’t surface. Panicked, Wyatt dives in after her. She resurfaces stunned but unharmed, and in his relief, Wyatt calls her “baby” and kisses her in front of everyone, exposing their relationship.

Blake and Wyatt face an interrogation from both sets, with Gigi present. Blake downplays the relationship as casual, but the fathers press for details about sex and pregnancy risks. Blake refuses to answer and eventually loses her temper, insisting she and Wyatt are consenting adults capable of handling their own lives. John storms out after Garrett suggests he’d prefer Blake with a Di Laurentis.

Blake hides in her room for the rest of the day. That night, Grace visits her and asks if Blake is happy and safe—Blake confirms she is—but expresses concern that Wyatt is a wanderer who might unintentionally hurt her. Blake texts Wyatt, and they agree to keep their distance for a few days. Beau then comes to her room and warns that Wyatt has a poor track record with women and will break her heart. Blake dismisses his concerns.

Three days after the public reveal, the fathers are still refusing to speak to each other, making dinner unbearable. Wyatt, suffering from insomnia without Blake beside him, goes to a bar with Beau, AJ and Gray, along with AJ’s girlfriend Tara. Wyatt notices Beau drinking heavily and acting angrily.

On the drive home, Wyatt texts Blake to meet him behind the boathouse. They have quick, urgent sex against the wall. Afterward, they hear sounds from inside and peer through the door to find Beau and Tara having sex on a workbench while AJ sleeps upstairs, completely unaware.

At breakfast the next morning, AJ storms onto the deck and confronts Beau, announcing to everyone that Beau has slept with Tara. He punches Beau repeatedly; Beau does not fight back. The adults allow it until Beau is bleeding, at which point Garrett orders it to stop and John pulls AJ away. AJ declares their lifelong friendship over, tells Tara to find her own way to the airport, and leaves.

Blake confronts Beau on the beach. He claims he was too drunk to say no when Tara came on to him. Blake accuses him of doing it because she rejected him for Wyatt, which Beau angrily denies. She tells him he needs to fix the situation and deserves to feel terrible.

Late that night, Garrett wakes Wyatt and tells him to meet him on the pier. Wyatt finds Garrett and John Logan in a boat, dressed in black. They motor out to the middle of the lake, where Logan asks Wyatt about his intentions with Blake and demands he name three things he likes about her. Annoyed, Wyatt ends up listing numerous qualities, revealing the depth of his feelings. Logan asks if Wyatt is in love with her. Wyatt denies it, but Garrett knows better. Logan gives his blessing but threatens harm if Wyatt ever hurts her.

Wyatt then learns that Garrett and Logan were never truly feuding—they’ve been hoping their children would get together since college. Wyatt is left feeling ambushed and unsettled by his own emotions.

The party staying at the lake house is now only Blake, Wyatt, and their four parents. Blake has been feeling unwell and Wyatt has been acting strangely. At dinner, the dads are suddenly and suspiciously enthusiastic about the relationship.

Blake and Wyatt visit the Spencers for a final goodbye before they return to New York. On the way, they pull over and have sex in the back seat. The Spencers reveal they have uploaded their podcast episode without Blake’s permission. It has gone viral with over a million views and earned $10,000. They propose making it an official series called “Fringe Benefits.” Encouraged by Wyatt, Blake agrees. They toast with champagne, but one sip makes Blake nauseous. While sick in the bathroom, she realizes her period is two weeks late.

The next morning, Blake takes a pregnancy test. It’s positive. Grace comes to the door, and Blake shows her the test without speaking. Grace hugs her and promises not to tell John until Blake is ready. Blake panics, insisting she’s not ready to be a mother. Grace reassures her she doesn’t have to decide immediately and will be supported whatever she chooses. Blake fears Wyatt will feel trapped or will try to do the right thing when he doesn’t truly want to. Grace tells her she is not alone. Blake sobs, overwhelmed.

Two days later, Garrett unveils the completed basement music studio to Hannah, who is moved to tears. Wyatt plays her a song called “Lightkeeper,” which she praises and recognizes is about Blake.

Blake texts Wyatt asking him to meet her on the dock. There, she tells him she’s pregnant, she thinks by about five weeks, and has a scan scheduled in two weeks. She assumes Wyatt will want her to terminate the pregnancy, but he refuses the assumption. He tells her he is equally responsible, will not run, and will be there for her regardless of her decision.

When Blake questions his motives, Wyatt says he loves her, that he thinks he has loved her forever but was too scared to say it. Blake is shocked and doesn’t say it back. She expresses her fears about not being ready for parenthood. Wyatt tells her they’ll wait for the scan and figure it out together. She rests her head on his shoulder.

The next day, Blake develops severe all-day morning sickness. After three days of constant illness, she and Wyatt decide to tell their parents. They hold a family meeting on the deck with their parents and Gigi on speakerphone.

John and Garrett are unexpectedly calm on hearing the news. Gigi quickly realizes the dads are happy because this is what they wanted all along; they admit they had already negotiated arrangements for this possibility, including a hyphenated last name and a babysitting schedule. Blake and Wyatt insist the pregnancy remain secret from the rest of the family for now. Blake reflects that, by telling their parents, they have limited their choices on whether or not to keep the baby.
