Values of the Waynes
Nolan depicts the Waynes as a loving family who only try to help others. They feel lucky to be in the position they are in, which is a rare trait for wealthy families. Their goal is to give back to their community and to raise a strong child who will do the same. Thomas seems to believe that people can overcome all of the damages they face with some help, which might reflect his occupation as a doctor.
