Calpourneiaa is shown as a very damaged person.
She is shown to lead a double life. This leads us to think that she is actualy very lonely. She can’t be a member of the Finch family and is excluded from the black community. She is neither here nor there. Neither a Finch or a solid member if the community.
“It was only then I realised she lead a double life”
This is the quote that shows us all of this.
