"The little one- the firstborn- has been poisoned by the scorpion," kino said. " He requires skill of the healer."
Then Kino's fist closed over the pearl and his emotion broke over him. He put back his head and howled. His eyes rolled up and he screamed and his body was rigid. The men in the other canoes looked up, startled,and then they dug their paddles into the sea and raced toward Kino's canoe.
"We will be married- in the church." All of these things Kino saw in the lucent pearl and he said,"We will have new clothes." "A rifle," he said. "Perhaps a rifle."
In chapter 4 it was based on kino getting ready to sell his pearl but he was so greedy that he did not take the offer.
In chapter 5 kino hits Juana in the face and on her side, his house burned down.
In chapter 6 kino was so focused on the pearl and so greedy that he accidentally killed the baby.
