1) How does the author use craft to reveal character in my book?

My book that I'm reading , Betrayed by P.C. Cast and Kristin Cast reveal their characters in dialogue and thought .

For example , " I didn't take over the Dark Daughters to start a war at the school , I took over because Aphordite was a bully , and she had to be stopped .......". This is saying that she is kind of a leader and she fights for what she believes in , and she knows what is right from wrong. Also another example is ,"Her own friends won't have anything to do with her ". This means she is really kind and she can forgive people easily  then other people .

This is how the authors use craft to reveal in my book.
