Cry of the Taniwha Prejudice Example

I was learning to make a Prejudice example about a character in the book "Cry of the Taniwha" to understand his personalities.
I found it easy because they gave us a lot of clues and facts about the character's behaviour in the book and I also really enjoyed reading the book.
My next step is to try find the characters personalities with less help from the book by making inferences (reading between the lines).
