6. Irony Review 
Dramatic – the audience knows something that the characters do not. 
Ex. We know that the old woman with the apple is the Evil Queen – Snow White does not.
Situational – When something occurs that is the opposite of what the characters AND audience expect. 
Ex. Dorothy journeys to find the wizard to send her home, only to find out that she had the power to do so all along. 
Verbal – the speaker says the opposite of what they actually mean
Ex. Belle tells Gaston "I just don't deserve you" as a way to fend him off. In reality, she means that he doesn't deserve her.
