The coming of age of Jem, Jeremy Finch, is shown in many ways throughout the book To Kill A Mockingbird by Harper Lee. He changes socially. He changes mentally. His feelings change emotionally. He also changes to become more of an adult figure. Another way he changes is that he changes physically.
Jem changes throughout the book socially by the way he starts having better feelings toward other people. There are many times when Jem start feeling bad for other people in the story, like when him and scout get in a fight but even though their mad at each other he still is grow up enough to know that he should say “Night, Scout.” There are also many other incidents, like when he goes out and teaches Dill how to swim. Jem also goes through some bad social change when he turns “twelve. He is difficult to live with, inconsistent, and moody.”(115). These are only a few of the things that Jem does to show that he is growing up in his social ways.
Mental change is another type of change that Jem goes through. Jem start to think like an adult as he gets older in the book. He shows it at the trial of Tim Robinson when the jury is in the jury room and he starts to talk to Reverend Sykes. He starts saying thing about the trial and Reverend Sykes ask him not to talk like that in front of Scout. Which shows that he knows what he is talking about.(see page 208-209). There is also the time when he had to go and read to Mrs. Dubose which he later finds out about her drug addiction which he fully understands. So those are ways he changes mentally.
Jem changes physically in many ways in the story. His hair stuck up behind and down in front, and I wondered if it would it would ever look like a man’s-maybe if he shaved it off and started over, his hair would grow back neatly in place. His eyebrows were becoming heavier, and I noticed a new slimness about his body. He was growing taller.(225) There was also when Jem tried to show Scout his hair on his chest which shows him growing up physically.(see page225) So these things show how he changes physically to become more of a man as he hits puberty. Another change that Jem goes through is his feeling toward himself and how he starts to feel better about himself. When he gets home one day from school he shows that he is all confident about making the football team and how happy he is to be old enough to play. But even though he doesn’t get to play he still remains happy with just being the water boy and just being able to be there watching. During the trial “It was Jem’s turn to cry.” which shows that he was not afraid to just let his feeling be show even though most people wouldn’t have.(212) So these show that Jem can feel good about himself and also feel bad but he can still let it out if he has to.
One of the most important change that Jem goes through is taking and adult role in Scouts life. He walks her to the school play and he protects her from Bob Ewell when he tries to kill them. This is the main one because if Jem did try and stop Ewell Scout could have died and it would have show that Jem didn’t really have an adult role. Also another reason is when Jem tells Dill that he shouldn’t touch Boo’s house because if Boo kills him no one will be around to keep an eye on Scout.(13) As you can see those where all ways that Jem shows his coming of age in the book To Kill A Mocking Bird by Harper Lee. By changing socially he becomes more likable. By changing emotionally with himself he becomes more confident. By changing mentally he starts to understand more complicated things that before he would have never knew about. By changing physically he becomes more of a man and is more older. And finally by changing to be more of an adult to his sister he becomes more aware of what an adult has to face.
