Rocky, limping from her bathroom fall, and Nick, sporting a budding black eye, arrive at the local Cape Cod surf shop with Willa, Jamie, and Jamie's girlfriend Maya to buy replacement swimsuits. Willa jokes about "Plungergate" to the cute shop employee, and Rocky notices Willa flirting; the girl ends up putting her number in Willa's phone. Rocky reflects on the many years her family has spent in this shop and on the Cape, recalling the unglamorous logistical reality alongside the natural beauty.

Jamie, Nick, and Willa quickly grab nearly identical black board shorts and gear, while Rocky struggles to find a one-piece that fits her aging, post-menopausal body. She admires Maya's youthful beauty and laments her own changing shape, trying on suits that are either too gappy or too pinching. A graffito noting the unceded Wampanoag territory prompts a passing thought about her body's irrelevance to history; she chooses the roomier suit, spending two hundred dollars and earning a "check your privilege" jab from Willa.

In the car, Willa scolds Rocky for calling Nick "Daddy," explaining the term's modern connotations. Rocky teases back but is internally uncertain. They head to the bay for a quick swim before clams. At the water, Rocky and the others hold up towels while Nick and Willa change and run into the waves; Rocky watches Nick bounce grown-up Willa like a baby and silently insists on the word "Daddy," recalling a memory of pregnant herself comforting four-year-old Jamie, who was afraid of the water and chanted that his father was okay.

As the sun sets, Willa and Nick return from the surf, and Rocky and Willa sing a line from "Sunrise, Sunset." Willa announces she's starving for clams, and Rocky realizes she is too—a small, warm closure to the chapter's meditation on time, change, and family.
