the bargirls hold a "wedding ceremony" for chris and kim ("dju vui vai"), with gigi toasting kim as the "real" miss saigon. thuy, kim's cousin, to whom she was betrothed at thirteen, arrives to take her home. he has since become an officer in the north vietnamese army and is disgusted to find her with a white man ("thuy's arrival"). the two men confront each other, drawing their guns. kim tells thuy that their arranged marriage is now nullified because her parents are dead, and she no longer harbours any feelings for him because of his betrayal. thuy curses them all and storms out ("what's this i find"). chris promises to take kim with him when he leaves vietnam. chris and kim dance to the same song as on their first night ("last night of the world").
