The author provokes naivety in the characters, making them not know the obvious things that the public already knows, creating humor from naivete.
Explanation:
The dramatic irony is identified in a text when the author uses symbols to pass messages to the public without revealing anything to the characters. This creates unpredictability for the character and an advantage for the audience that is following the story. In this case, the author can create humor (where the audience laughs at the character's naivete and therefore his inability to act correctly) or suspense (letting the reader know the element of drama that the character is not aware of).
