why cause kino's reaction at the end of the chapter? what could he possibly be thinking after all that has happened?

"Instinctively Juana went to Coyotito where he lay on his father's blanket. She lifted the poultice of seaweed and looked at the shoulder.

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."
