dramatic irony is perfect for script! dramatic irony is when an audience knows something that the characters (or at least the main character) does not know. as you can see, it is especially useful in a drama script because the audience gets to see this “secret” even in front of their own eyes. it creates a sense of appreciation— the audience wanting to inform the main character of what they do not know. it is always satisfying to see this conflict resolved, and could give the writer an easy but yet compelling ending. if the conflict is left unsolved this could also leave the audience with a sense of empathy for the character who did not know of this “secret”
