Don John, who is Don Pedro's illegitimate brother, walks with his companion Conrade. Although Don John is infamous for his lechery and violence, Don Pedro welcomed him as a companion anyway to give him a second chance. Don John, however, is not prepared to fawn and grovel his way into society's graces; he has returned to his old ways. Don John's henchman Borachio enters and tells him about the impending Hero-Claudio marriage. With this information, Don John devises a method of simultaneously wreaking havoc and getting his revenge on Claudio and Don Pedro. The trio leaves to further plot their scheme.
