A broken air conditioner sends the Pearson family to a public pool, where three simultaneous crises unfold: Kevin nearly drowns while both parents are focused elsewhere, Kate is shut out by other girls for her weight, and Randall drifts toward the Black children at the far end of the pool — prompting a stranger to tell Rebecca what she has been missing about raising her son. In the present, William is reported for loitering in Randall's neighborhood, Randall apologizes to defuse the situation, and their argument exposes two incompatible survival strategies. Kate accidentally gets hired at Toby's ex-wife's boutique, and Toby reveals the depth of what his first marriage cost him. Kevin bombs his Broadway audition but gets cast anyway — for his TV name — and moves in with Randall.
