Tamino and Pamina have to go through the last trial together. Papagena enters and dances, then, when Papageno promises to be true, she throws off her disguise and disappears. Pamina thinks her mother is going to use her dagger, but at the last moment the boys save her and take her to Tamino. Tamino plays the flute as they go together through fire and water. The chorus sing in triumph.
