Giovanni, who had previously abandoned Donna Elvira, now flees, referring her to Leporello, who recites the catalogue of Giovanni’s conquests. Masetto and Zerlina, soon to be married, celebrate with their friends. Giovanni orders Leporello to escort Masetto and the peasants to his villa. Once Masetto is gone, Giovanni seduces Zerlina. Elvira warns the girl to avoid Giovanni. Anna and Ottavio request Giovanni’s help in punishing the Commendatore’s unknown assassin. Elvira returns, but Giovanni dismisses her as a madwoman. Once they’ve gone, Anna suddenly realizes that this was, in fact, her father’s murderer.
