Quickwrite 2-28-12 Tuesday Character Change

In the outsiders, Johnny changed from being soft spoken to being more confident in his thoughts and opinions. I know this because in the first couple of chapters, he's always defending Dally and is very quiet. But all of a sudden after he kills Bob, he starts to act more independent. After all it was his idea to turn himself in ; which if you were to hear this in the beginning of the book, you would think that he was a totally different character.
