Sincere,at the beginning of the movie he offers him his jacket. he was also sincere because he was friends with Plato even when no one liked Plato and he was his only friend and he treated him kindly.he also ran after Plato after he tried shooting him and wanted to keep him calm to be able to take him out the planetarium safely.
Determined,he is determined to start a new life and stop moving, "for once i want to do something right! And i don't want you to run away from me again". He is also determined to make his dad stronger and have courage to stand up to his mom and stop being a chicken"
Jim changed through out his experiences in the movie mostly towards then end because while they were hiding in the abandon house and he was with Judy he realized that being caring and was a not a bad thing and didn't make him or his father a chicken.
The chickie run was an important symbol because its a symbol of peer pressure.
I think the theme of this story is that teens rebel over things that they might not notice and that peer pressure leasing cause to rebellion. I think this is the main lesson because all three teens had family problems and there parents did not understand the reason for there rebellion, and because peer pressure and wanting to fit in led them them to having problems.
"why do you think being called a "chicken" really gets to Jim? Why do you think that the other kids give Jim such a hard time?"
I think that it really got to Jim when they called him a chicken because he didn't want to be known as a weak person and wanted to show that he was a man and he could take control of any situation.I think the other kids gave a hard time because he was new and because he was trying to fit in with them and buzz was peered pressured to mess with him.
