Red Pyramid- Character Development

As the story progresses, it seems that, so far, the characters have stayed pretty much the same. Sadie has been from the beginning very curious and outgoing. She actually starts go get more so when she learns about magic and just goes right ahead to explore a forbidden place that could be highly dangerous. Carter is still hesitant to do those things with her, but always gets convinced and helps her out. They learn some new things and Sadie tries to use magic, but she gets faint and weak. Basically, they haven't changed much and they have a lot to learn.
