As the days pass, Viola falls in love with the duke, but the latter has eyes only for Olivia, with whom he presses his page to renew his suit. When Cesario delivers another message from Orsino to Olivia, the countess openly declares her love for the young page. Cesario insists, however, that his heart can never belong to any woman. So obvious are Olivia’s feelings for Cesario that Sir Andrew becomes jealous. Sir Toby and Maria insist that Sir Andrew’s only course is to fight a duel with the page. Sir Toby delivers Sir Andrew’s blustering challenge, which Cesario reluctantly accepts.
