The document discusses three theories of narrative:
1. Todorov's Narrative Theory which states that stories follow a five step pattern of equilibrium, disruption, realization, restored order, and equilibrium again.
2. Propp's Narrative Theory which identifies character archetypes that appear in stories like heroes, villains, mentors, etc.
3. Levi-Strauss's Narrative Theory which says that opposites like good vs evil are used in stories to reinforce themes through binary relationships. Examples given are vampires vs werewolves in Twilight and Harry Potter representing good vs Voldemort representing evil.
