Isolier is in love with the countess. He doesn't recognize Ory in disguise, and Isolier confides his love to the hermit, explaining his plan to sneak into the castle disguised as a female pilgrim (Duet: "Une dame de haut parage"). Isolier asks for the hermit's help: when the countess comes to him for advice, he should tell her that her torment is caused by her indifference and that the cure is to love Isolier. Ory likes this idea, but he is resolved to use it for his own ends.
