On Monday, June 30, Alice wakes to hammering across the bay and notices Charlie Florek’s yellow boat from her bedroom window. In the living room, Nan is absorbed in old photo albums, recalling early cottage years in the late 1960s when there were few amenities and the families worked on the place together.

Alice asks about Nan’s contact with John Kalinski, and Nan admits they have not spoken in years. Nan reflects that losing people changes things, a reference to the death of Alice’s grandfather David, and ends the discussion by asking to leave the past alone. Alice offers support and breakfast, then steps outside to eat.

With the construction noise ongoing, Alice imagines Charlie building his tree house and texts him a teasing complaint. She helps Nan complete her prescribed exercises, noticing Nan’s improved strength, and the two start sewing simple rod-pocket curtains. Nan coaches Alice through the machine work until Alice completes a panel successfully.

Nan encourages Alice to take a swim. When Alice checks her phone, she finds a flirtatious reply from Charlie calling her “princess.” She brings binoculars to the dock, scans the shoreline, and spots Charlie shirtless on his deck. When Charlie notices her and smiles, Alice dives into the lake to avoid being caught staring and swims laps until winded.

Back at the dock, Alice struggles onto a giant unicorn float, finally settling onto it as Nan laughs from the deck. The peace is broken by a Jet Ski making repeated passes around the bay, drawing nearer before stopping close by. A voice calls out, “Lucky Pegasus,” leaving Alice’s attention pulled to the new arrival.
