This passage highlights Jacob’s struggles with his family—particularly with his dad. The implied tension between Jacob’s parents, and the more obvious tension between them and Grandpa Portman, suggests that family can be loving and supportive, but also difficult and complicated. Moreover, the book illustrates how Jacob’s dad has never fully come into his own because of his wife’s money. Like Jacob, he is stuck in a kind of immaturity, with little agency or sense of purpose.
