Unfortunately, Kino and his wife Juanita are unaware of the poison of envy in so many that their pearl has created. When the neighbors come to see the beautiful pearl that Kino holds in his hand, some become jealous of Kino, wondering how such luck could come to any man. Kino's brother Tomas asks,"What will you do now that you have become a rich man?" (III)
When the dealers hear of this marvelous pearl, they are excited because they have also learned that a peasant has found it. Such a man knows not how these dealers work together; furthermore, he is not aware that they all work for the same man.
