After returning home from the pearl buyers' office, Kino and his brother Juan Thomas discuss what has happened. Juan Thomas warns Kino that if he goes to the capital, Kino may meet with only more disappointment. After his brother leaves, Kino hears noises outside; upon looking outside, Kino steps out and is struck on the the head. Cleaning his wound, Juana tells Kino,
