Questions about Restart for you.

Dear Gordon Korman,

I have read your book Restart and I have A few questions  about Restart? 1 of my questions is why did Aaron and Bear not change my class was really hoping Aaron would change because every now and then Aaron would do something that would make us feel like he was going to change and not be a bully and Bear would be the only one left. Another question I have is what was the reason  you made chase falling off his roof and getting amnesia. My last question is what was the climax of the book because there are a lot of big moments in the book.
