Don John in Much Ado About Nothing

Don John

Don John is a thoroughly unpleasant character. Some readers say he is too evil to be believed, He appears first in Act 1 Scene 1 as a sulky and bad-tempered character. He says he is honest in that he admits his true nature, though in fact he is untrustworthy.

He is jealous of Claudio and plots to damage the soldier's new-found romance with Hero. With Borachio and Conrade, Don John sets up a scene that appears to show Hero being unfaithful. The audience learns that they intend to trick Claudio by showing him Margaret declaring her love for Borachio and making him think she is his wife-to-be.

At the end of the play we learn that Don John has tried to escape but is arrested and brought back to Messina.
