Writing Fantasy Moments - Dramatic Irony

Ya wonder how storytellers use Dramatic Irony to make your jaw drop? Set-up. All it takes is the reader knowing one more fact than a character. That stirs up a whole hornet's nest of emotion in the reader.

Writers, do you use Dramatic Irony? How and why?

Curtis, the M.C. of a story I wrote, tracks villains using a type of telepathy. Curtis hears people speaking from miles away, and he tries to warn police officers when the villian plans to bomb a target. Dramatic Irony comes in when officers doubt Curtis's telepathy, and early on when Curtis first developed it.
