A reader might know things that the characters do not.
This option effectively captures how the reader's point of view can create both suspense and humor. For suspense, if the reader is aware of a secret or danger that the characters are oblivious to, it creates tension as the reader anticipates the characters' reactions. For humor, the reader may find irony or comedic value in a situation where the characters are naïve or misinterpret events, while the reader understands the full picture.
