In one passage, Bahi recalls what Pavelos once said to him, "Do not come closer to history, oh Bahi! Do not go deeper." He remembers his disapproval question about whether he believed that history was a vast sea that textbooks reduced to the borders of charming sandy beaches and that deepening it would open doors for him to swim in Those alluring waves.

"No, son, history is a quagmire and an ornament. Schoolbooks have chosen its sides, prevented you from diving into it and discover that everyone is human. They defended what they believed in their own way. And alliances, focus on them in the exam, but it blinds you from the means. "
