this relates to the wave because if you disobeyed the wave you would get punished. you would get threaten and death threats etc… this is the concept of loyalty. loyalty is the the quality of being loyal to someone or something. in the movie Mr. Ross gave the students id cards and some of them had a red x on it. If yours had a red x it means that you spy and tell if someone does not follow the rules and they will get punished. Ben is like the body guard if the wave people saw someone breaking the rules they would report to him and Ben would report to Mr. Ross.
