What does Kino propose once they get into the mountains? Do they go through with his plan

Kino proposed to go onto ahead of Juana and the baby, so that they would be safe. This might allow Kino to get past them and meet them later. They do not go through with this plan because Juana refuses.

"Juana," he said, "I will go on and you will hide. I will lead them into the mountains, and when they have gone past, you will go north to Loreto or to Santa Rosalia. Then, if I can escape them, I will come to you. It is the only safe way."

She looked full into his eyes for a moment. "No," she said. "We go with you."
