Much Ado About Nothing — Act 3, Scene 2: A room in LEONATO'S house

In Leonato’s house, Don Pedro, Claudio, Benedick, and Leonato talk about the coming wedding. Benedick acts gloomy and excuses himself by claiming a toothache, then draws Leonato aside for a private talk. Don Pedro and Claudio decide Benedick is really in love, probably with Beatrice, and joke that Hero and Margaret have already helped match the pair. Don John then arrives and pretends to reveal a serious problem: he claims Hero is unfaithful and says Claudio should see proof at her chamber window that night before deciding whether to marry her. Claudio and Don Pedro accept the warning and agree to watch with him.
