In Shakespeare's Much Ado About Nothing, Don John is the jealous brother of Don Pedro. Both are soldiers, but Don Pedro reaps the recognition for being the captain of a successful corps of men. Not only that, but Don Pedro, in Don John's mind, seems to favor Claudio more than his brother. Hence, Don John comes up with a scheme to break up the wedding between Claudio and Hero out of revenge. Don John sets Hero up to look like a harlot, and tells Claudio about Hero's discretion in Act III, scene ii. After Don John plants the seed of doubt in Claudio's mind, he says, "I will disparage her no farther till you are my witnesses. Bear it coldly but till midnight, and let the issue show itself"(III.ii.111-113). Afterwards, Don John meets Don Pedro and Claudio at the appointed place where they think they see Hero with another man. Don John's scheme is taken as truth and thereby causes more pain and anguish for Claudio and Hero just as he planned.
