On the next day, the Principal asks Andrew and other bullies to come into his office. When they go into the Principal's office, they see that Aaron and Hassan are also there.
The Principal says to them, "Aaron and Hassan already have shown me the video in which you guys were saying about your bad deeds. So I've decided to expel you from the school as you not only copied Aaron's work but also locked him up for two hours."
After this incident, Aaron never lets anyone bully him and he also joined the club called "No Place for Bullies", he and Hassan helps others who go through bullying and teach others how to overcome bullying and what to do if you're going through bullying.
