I found it interesting that Faulkner decided to introduce new characters throughout his novel, Light in August, and proceed to write them out of his story. These cameos, performed by such characters as Grimm or the blonde behind the couter at the restaurant Christmas frequented, provided important insight into the thoughts of the people in town.
Grimm was introduced solely for the purpose of hunting down Christmas. Although Grimm held the same prejudices as the townspeople, he acted on his attitudes to an extreme that the citizens would never mimic. Grimm was introduced into Light in August in order to act out the private thoughts of the townspeople. Although the townspeople would never act on their prejudices in the extreme way that Grimm did, their prejudices were so passionate that they believed Grimm's actions to be necessary. Grimm acted in such a vicious way towards Christmas because the townspeople wished it to be done.
