Rocky wakes Monday morning in the loft bed beside Nick, who is reading. She reflects on the slow, luxurious early days of vacation that always seem to vanish by Friday. Nick tries to initiate sex, but Rocky stops him, aware that Willa is sleeping nearby. Rocky muses about Nick's family's tendency to communicate exclusively through movie quotes and dad jokes, recalling how she once worried this signaled emotional shallowness, until she saw him tenderly whispering to newborn Jamie.

A small disagreement escalates when Rocky, hormonal and exhausted from menopause, erupts in rage about the unfair burden women carry—doing all the hard work while still being expected to be desirable. She cries, asks Nick if they should split up, and he reacts with hurt frustration. They reconcile through humor and a Brokeback Mountain quote, with Nick patiently affirming their bond. Willa overhears from below and teases them.

Rocky reluctantly joins Nick for a run on the bike path, where they forage for chicken-of-the-woods mushrooms and complain about aging bodies and plantar fasciitis. Rocky vents about her father's recent comment ranking Willa as his favorite grandchild over Jamie, which had upset her. Nick gently affirms that her dad is imperfect but still loved.

Back at the cottage, Willa wants to spend the day with them and chooses the bay beach to look for hermit crabs, mentioning she had been in Provincetown the night before. Rocky reflects on how layered Willa has become through years of vacationing here, and on her own aging—she was twenty-nine on their first visit. Rocky cooks the foraged mushrooms in butter, and she and Nick share coffee on the sunny deck, ending the morning reconciled.
