"What do you plan on doing when you come up there —if I let you come up there?" Guidry asked me.
"I have no idea, sir," I told him.
This conversation shows how Grant does not really know what he is trying to teach to Jefferson, much less how he will go about teaching it. He has an idea of what Ms. Emma wants, but does not seem very certain about why she wants him to spend time with Jefferson. The fact that he continues on this journey despite this uncertainty is a sign of his heroism.
Grant is also the one who changes the most during this novel. In the beginning, he is an educated but sort of naive man who doesn't recognize the cycle he helps to perpetuate. However, because of the challenge that Jefferson presents him with, he comes to realize that the black community is trapped in a cycle of ignorance and oppression. His part in the oppression becomes apparent to him when the superintendent visits his school and looks at all the children's teeth while they stand in perfect lines just like he taught them to.
"Rise," Irene called to the class.
They came to their feet, their heads up, their arms clasped to their sides. But instead of feeling pride, I hated myself for drilling them as I had done.
This is when he starts to see how he himself is part of the power structure that has put Jefferson in prison on purely circumstantial evidence. In the follow chapter he begins to see what his old teacher meant when he said that attempts to change the situation were futile. Grant realizes just how continuous this cycle is while he watches his students chop wood for the winter.
And I thought to myself, What am I doing? Am I reaching them at all? They are acting exactly as the old men id earlier. They are fifty years younger, maybe more, but doing the same thing those old men did who never attended school a day in their lives. Is it just a vicious circle? Am I doing anything?It is in this moment that he makes the transition from being a passive school teacher who plays along with the system to someone outside the system who sees it for what it is. This is what sets him apart from the other characters in this book and what makes him a hero.
