At first it was thought that Ugalde's daughter Marguerite would take over, but the director then approached Jeanne Granier, who, after only having heard a play-through of the first act, took on the double part of Jacquette-Jacquet.
As a loving friend, she covers for her cousin by dressing up in men's clothes, compromises Bianca thus forcing the marriage to take place.
Jacquette, now Jacquet, dressed all in white, reluctantly goes to marry the young and beautiful Bianca, but implores Perpignac to relieve her of the wedding night duty ...
In the end, Bianca, who is loved by the chamberlain of the duke of Parme, gives in to the charms of this chevalier Pomponio, and the Béarnaise Jacquette returns to Béarn with Perpignac.
The music of the second act was received more warmly than the first, with Maugé's couplets "Très souvent à la devanture" encored, along with Vauthier's madrigal "Chacun, madame, à votre aspect", Granier's song "C'est du vin de Gascogne" and Mily Mayer's couplets "Pour un détail, une nuance".
