Hero’s innocence is eventually uncovered by the very silly Constable Dogberry. Before there is any proof, Friar Francis and Hero’s cousin Beatrice are convinced that she is not guilty of being unfaithful to Claudio. The friar says that Hero’s blushes and the “fire” in her eye have persuaded him that she is blameless. Beatrice knows that it is not in her pure cousin’s nature to do such a thing. Even Benedick finds the situation odd.
Meanwhile, Dogberry’s men have overheard Conrade and Borachio admitting that they and Don John tricked Claudio and Don Pedro into believing that Borachio was having an affair with Hero, when really it was with Margaret. They arrest them, and eventually Borachio confesses and appears to be penitent. Don John also admits his guilt by running away. At this point, quite of bit of damage has been done to Hero’s reputation. However, this is a comedy, so her friends and family find a way to restore her name and reconcile her with Claudio.
