The wedding begins early the next day. Panza is impressed by the huge feast on offer. Everything has been paid for by the wealthy Camacho. Quixote and Panza take part in the celebrations, watching the dancing and theater performances. The actors put on a satirical show about money and love. After seeing Camacho’s wealth in person, Panza is convinced Quiteria will marry Camacho rather than Basilio. Quixote believes that she is making the wrong choice. 

Camacho and Quiteria begin their wedding. Basilio interrupts the ceremony. He brandishes a knife and then kills himself, using his last words to ask Quiteria to marry him. She agrees and marries Basilio so he can seek forgiveness from God as he lays dying. Then, Basilio reveals his suicide was a ruse. A fight breaks out. Quixote stops the fight and demands people cease their violence in the name of love. Though Basilio and Quiteria stay married, Camacho takes solace in knowing his wife would never have truly loved him. Quixote and Panza leave the wedding to follow the newlyweds away from the village.
