When they arrived at St. Francis Academy, Belle and Eli checked Neon's classroom first and found him reading a book with his teacher watching over him.
Teacher Ady apologized to Belle and Eli for what her students did and informed them of the action plan that the school took against the students who were involved.
As someone who was viewed to be kind and friendly, Belle didn't make a big deal out of it. Whatever the school wants to do didn't really matter to her. The only important thing for her was to get rid of those students from Andrei's life and make him have a great time at school with people he can truly call friends.
It also didn't matter to her if the students wouldn't really befriend the child as long as they won't stand in his way as well.
