Dramatic Irony
The audience knowing more than the character — the oldest machine of tension there is (we know what's in the basement; the character opens the door).
Distinction: Subtext is born in the character (what they can't say); dramatic irony is born in the audience (what the character doesn't know). One sits under the line, the other over the scene.
Common mistake
Setting up the gap in knowledge and not using it: if the audience knows, every scene should carry the pressure of that knowledge.
Example — The Tea Scene
The scene opens on Cemal: he's sitting at the till, an open ledger in front of him, striking out the figures and writing them again. His son Emre comes in afterwards.
The order is a choice: the audience sees the ledger before Emre does. When Emre brings the job offer we know something he doesn't — how badly the offer is needed. When Cemal turns the ledger over and pulls it towards himself ("Have you seen the ledger?") that movement says two things to two audiences: to Emre, "subject closed"; to us, "he can't close it."

How to set it up
- Give the audience the information first. One shot, one action line is enough; no explanation needed.
- Give the character who doesn't know a job on top of that information. A gap in knowledge isn't tension on its own; the pressure comes from the character doing something that will collide with that knowledge.
- Write every scene under that gap. If the audience knows, every sentence from the one who doesn't carries a separate meaning — if it doesn't, the gap was set up but never used.
- Choose the moment the gap closes. Dramatic irony is a debt; if it isn't paid, the audience feels cheated.
Check
Reread the lines of the character who doesn't know: if you didn't know what the audience knows either, would those lines say the same thing? If yes, the irony isn't working in the scene.
