How do Don Pedro and Benedick react when Claudio says he loves Hero in Much Ado About Nothing by William Shakespeare?

When Claudio declares his love for Hero in Much Ado About Nothing, Don Pedro and Benedick react with surprise and amusement. Don Pedro, who has been helping Claudio woo Hero, is pleased that his plan has worked and remarks, "I pray you, come; Hero is here at hand, / I would not have her miss this data; than all / The wealth of Messina. But soft, here she comes." Benedick, on the other hand, is more skeptical of Claudio's sudden change of heart and teases him, saying, "Come, you are in love. By'r lady, I am sorry for you; for it is stark love and madness." Despite their different reactions, both Don Pedro and Benedick are supportive of Claudio and Hero's relationship and hope that it will lead to a happy marriage.
