The Consul and Kate remain, waiting Butterfly to wake up. When she wakes and goes in the living room hoping to see her husband she sees Sharpless and an American lady. She questions Suzuky who is unable to answer, and realizes the gravity of the situation. She says that she will give her son to his father only if he will be there to take him in half an hour. The Consul and Kate go away.
Butterfly simulating a game blindfolds the baby and goes behind a screen.
Soon after enters Pinkerton, shouting her name. The man runs and holds the dead young Japanese, while the baby, unaware of the tragedy, is still playing.
