Cassie seems secretive because she had not told her parents about how her boyfriend lost her tablets and how she broke her tablets and how she did not tell her mom and dad about how she has two matches.
Cassie is an archetype of a hero who is coming of age. She is slowly enlightened to the truth of her world and dystopia. Cassia begins the story as a comfortable, happy pawn in the Society’s totalitarian game. As she slowly becomes both self-aware and aware of the Society’s fallibility, she begins to question the status quo. Over the course of the book, she becomes completely disillusioned to the Society's lies; ultimately, she is willing to betray her Match with Xander for the chance at liberation and happiness with Ky.
