Cal and Aron both have ideas in their head of what their mother was like, and these ideas are polar opposites. Aaron believes that his mother was a good person who died because she was “too good for this Earth”. Cal, on the other hand, believes that since their father is so good, Cal must have gotten his badness from his mother. When he finally meets his mother, he finds that his idea of her is more accurate that Aron’s. His mother tells Cal that she left his father because she felt he was too good, and she couldn’t stand it.
Aron’s girlfriend, Abra, doesn’t believe herself to be good or bad. Aron fell in love with her because he saw her as good and pure, like his concept of his mother. Abra doesn’t believe herself to be this person and begins to drift away from Aron, feeling she can’t live up to his standards, and she starts to fall for Cal.
