What is meant by the words that were on the board when Daru returned from his journey in "The Guest"?
Daru was supposed to escort the Arab prisoner to the police station in Tinguit for having committed a murder. After getting to know the Arab, Daru could not turn him in. So when they arrived at a fork in the road, Daru gave the Arab a choice: If he took the south path, he would end up with people who would take him in and help him. If he took the east path, he would end up in Tinguit where he would be arrested and probably executed. When Daru walked away, he looked back and saw that the Arab had not moved from his spot. He looked back again a little while later and noticed that the Arab was walking toward the east. When Daru arrived back at his schoolhouse, someone had written on the chalkboard: "‘You handed over our brother. You will pay for this." Even though Daru had given the Arab the chance to escape, the Arab chose punishment. His friends did not know that and thought Daru had taken him to the police. Now Daru has to fear for his life.
