BRAVE. Jem shows his bravery when he takes Dill's dare to run and touch the Radley house, but he risks his life to protect Scout from the murderous Bob Ewell later in the novel.

Sensitive - Jem cares about what his father thinks of him, he wants to obey. He does love his sister and cares about her well being even though he likes to make her think otherwise.
Pensive - This means thinking. Jem is a serious thinker that Scout notes throughout the text. Sometimes he would wander off to behind the car house and just think. She thinks he would often recall their mother whom she had such little recollection of.
Adolescent - Jem thinks he is growing hair, he stuffs his face with bananas for football season next year, and he is referred to as Mister Jem. Also, he is often moody.
Just - Jem struggled with the verdict of the trial because it wasn't fair. He couldn't justify in his mind why men would be so terrible as to not accept the truth.
Obedient - Even though Jem did wrong things, he accepted life's consequence. Take the incident with Mrs. Dubose for example. She really cracked him. He would have liked to not have to go over there and read every day. But he does it because his father instructed him to do it.
