Flood walked over to Fighting Theory class, and stood in front of the door. Batman wanted him to be a teacher's aid for a subject and he felt like Fighting Theory would be the best class for him to help in. His strategical mind when he wasn't insane was incredible and all the voices in his head gave him multiple perspectives when he was fighting. It was only natural that he be the aid here. He walked in and wrote a quick note for the teacher, whoever it was. 'I am going to be the teacher's aid for your class as per Batman's orders. If you don't like it take it up with him.' He then moved around his desk so he would be next to the teacher's desk.
