They love each other hopelessly. Much of the play deals with how we fool ourselves and how we are fooled by others. Claudio and the Prince are tricked into believing a lie about the virtuous Hero. Beatrice and Benedick are tricked into believing the truth about themselves. And the self-deluding Dogberry discovers the truth that ultimately exposes all the lies in the play.
Perceptions become reality and the truth is something that is accidentally overheard.
On a personal note, Much Ado About Nothing was my first play with Montana Shakespeare in the Parks. I played Don Pedro and that was twenty years ago. It is a great gift for me to return to sunny Messina and this glittering human comedy. They are returning from battle with the Prince's scheming bastard brother Don John in which Don Juan has been subdued and forgiven. The Prince's followers include the heroic Claudio and confirmed bachelor Benedick, who maintains his own battle of wits with Beatrice.
