Activities had already taken place in his class, teachers had taught and left. Throughout those activities, Aiden kept on thinking about where and when he could battle those bullies and deal with them.
First of all, he needed to inform them that he wants to battle them today. For sure, they'll agree, they'll definitely underestimate him...they'll want to beat him up.
And best of all, he'd tell them he wanted them to do it out of school, they'll be so happy, they'll be able to beat him up as they wanted. Secondly, he needed to find a way to go out of school before Oliver and Ava, he needed to give them an excuse.
These were the thoughts that kept on running through his mind while he was in class, he kept on contemplating...and he came up with an idea for both problems.
