What surprising thing did Juana do after Coyotito was stung by the scorpion

Juana asked her husband to get the doctor.

Kino had wondered often at the iron in his patient, fragile wife. She, who was obedient and respectful and cheerful and patient, she could arch her back in child pain with hardly a cry. She could stand fatigue and hunger almost better than Kino himself. In the canoe she was like a strong man. And now she did a most surprising thing. 

"The doctor," she said. "Go to get the doctor."
