Curiosity drives C.W. influencing him to snoop and be sneaky. It pushes him into trouble at just about every turn. His curiosity is unwanted and in some way unwarranted.
My big question for Tuesday’s class was: How does trust play into the characters relationships with each other. loyalty vs. suspicion vs. trust.
now it seems that no one character trusts another which seems a very realistic human trait. I think that it is the fact that there are no certain heros that ups the readers curiosity of the story while C.W’s curiosity is heightened by the lack of trust.
ultimately without Caleb’s curiosity there would be no story no interest for the reader. But at times it is annoying and at others seems down right idiotic. who snoops through their masters chest without having a look out? I mean really! 
I think the topic of trust is very important one in this book. I think your comment about it being idiotic is a statement on real life and that it is directed towards the relationship between the government and the governed. It seems as though this story is meant to be an in depth commentary on the heirarchy of society and seems to screw around witht the traditional roles which people should take in society.
