After a performance, the troupe tries to guess Granny Anna's age and how to celebrate her upcoming birthday. Nadja is unaware that her father, her mother and her mother's new husband (Count Albert Waltmüller) are nearby. Collette is bound for a hotel to talk her nephew, Oscar Colorado, into attending a debutante ball. She met her first husband, Raymond (who was killed in a train accident), at a ball. After Raymond's death, Duke Preminger ordered Collette to return to Vienna and Nadja to be placed in the orphanage. Collette senses that Nadja is searching for her, despite Bianco and Rosso's pursuit of Nadja in Milan, and Duke Preminger expects Nadja to earn her inheritance.
