How we cite our quotes:
The two came from the rutted country road into the city, and they were not walking in single file, Kino ahead and Juana behind, as usual, but side by side. The sun was behind them and their long shadows stalked ahead, and they seemed to carry two towers of darkness with them. (6.100)
Because they have suffered together, Juana and Kino are now equals. They have overcome the restrictions of their genders.
And when they came to the water's edge they stopped and stared out over the Gulf. And then Kino laid the rifle down, and he dug among his clothes, and then he held the great pearl in his hand. He looked into its surface and it was gray and ulcerous. Evil faces peered from it into his eyes, and he saw the light of burning. And in the surface of the pearl he saw the frantic eyes of the man in the pool. And in the surface of the pearl he saw Coyotito lying in the little cave with the top of his head shot away. And the pearl was ugly; it was gray, like a malignant growth. And Kino heard the music of the pearl, distorted and insane. Kino's hand shook a little, and he turned slowly to Juana and held the pearl out to her. She stood beside him, still holding her dead bundle over her shoulder. She looked at the pearl in his hand for a moment and then she looked into Kino's eyes and said softly, "No, you." (6.103)
When Kino offers the pearl to Juana, it’s his way of apologizing. When Juana allows him to get rid of the pearl, it’s her way of forgiving him without compromising his masculinity.
