He persists with his questions, asking if she has been banished long ago and, finally, apologises for his intrusion. In an extended duet, first he, then she, then together proclaims: "Serba, serba i tuoi segreti" / "Keep, keep your secrets...but it is in vain to forbid me to love you", while she responds with "Taci, taci, è l'amor mio / condannato sulla terra" / "Hush, hush, my love is condemned upon this earth; I cannot associate you with a destiny that is so hostile towards me". She tells him that she will reveal nothing about her past and begs him never to return. However, as the duet continues, she exclaims: "Ah! would that I could so easily / Erase you from heart", admitting an attraction to Arturo. He says that he will continue to follow her "even into a desert" while she responds: "Your wish will prove your undoing".
