When Cole apologized to Garvey and Edwin, what did they tell him?

From the text:

“Don’t apologize to us,” Garvey said. “Apologize to yourself. It’s your life you’re betraying. Not ours.”

Edwin held up his hand. “Stop your mindless talking! Your words insult me! They’re just noise in the air— they don’t mean anything. Tomorrow morning, I want you to get up alone and soak. Then I want you to carry your ancestors and roll your anger away. When you return to camp, we’ll see what you’ve learned.”
