Jeremy Finch is the older brother of Scout Finch who is the narrator of the story. He ages from 10-13 over the course of the book. The changes he goes through are seen from his sister (Scout’s) point of view.
Jem could be described as being brave and idealistic. His character is largely influenced by his father Atticus, an upright character whom he idolises.
As the story develops we see him growing in bravery, from always accepting a dare to seeing how his father dealt with various tough situations like the incident with the vicious dog, to dealing with Mrs Du Bose and her fight with morphine addiction. Also seeing how Scout dealt with confronting the angry mob outside the jail. So, as he grows older and develops he learns to do the right thing even though it may not make him popular with everyone around him. We also see him growing from a boy into a young gentleman, ready to protect his sister.
Jem can be seen as being idealistic when he is ready to overthrow the justice system when he does not agree with the jury’s conviction of Tom Robinson. We see in situations like this that his coping skills are still developing and it is his family’s support that helps him.
SCOUT ( JEAN) FINCH:
Scout Finch who is the young narrator of “TO KILL A MOCKING BIRD”, identifies as the questioner and the observer throughout the novel.
There are really two Scouts present in the novel, a young Scout who is experiencing the story and the adult Scout that is telling the story. The adult Scout can better understand the impact of the events that the young Scout is experiencing.
Scout is the younger sister of Jem Finch and the daughter of Atticus Finch. She is someone who loves to question and observe things. She is a tomboy and is physically strong for someone her age and intimidates many of the boys at school. She can be seen as outspoken and honest. These characteristics are however, looked down upon by some of the older ladies in the story like her aunt Alexandra and Miss Caroline, her teacher.
One big lesson she learns from her father is seeing how it is to be in someone else’s shoes. Her father shows her shortcomings and demonstrates his point to her in his own interactions with other people. She is then able to put herself into Mr Boo Radley’s shoes, the person she feared the most in the story.
