There was also when jemtried to show scout his hair on his chest which shows him growing upphysically

What do you mean by this? this part where Gem shows Scout his hair is to show readers that Gem is changing, he's becoming older and more wiser about things, the author is trying to tell us that time is changing.

Ihope i’m doing this right sooo bullying, slide show, and then answer the question pls comment if i did it wrong hope this
