For example in a story I'm writing a character says the following:
“Be careful,” An-Mei said, ignoring my question. “No matter what, don't get close to her.”
Later on the protagonist thinks about this:
I had decided to avoid the mountain at night. Be careful. Don't get close to her, An-Mei had said. But did why people fear her so much?
Should I italicize Be careful. Don't get close to her?
