The best statement that shows Peter's personal connection to Jack Will's character is the following:
"At first, Jack Will seems bored with August and the school tour. But at the end of the chapter, he tries to help August. I understand how this happens, because my best friend and I did not get along when we first met."
This response highlights Peter's ability to empathize with Jack Will's transformation from indifference to support for August. By relating Jack Will's experience to his own friendship, Peter demonstrates an understanding of how initial misunderstandings can evolve into supportive relationships, providing valuable insight into Jack's character development.
