Also known as plant/payoff · setup and payoff
A setup early in the story (the plant) that returns later with new meaning or consequence (the payoff). The audience feels clever -- and the turn feels earned -- when both halves connect.
A plant should be visible enough to remember and quiet enough not to spoil. Put the loaded gun, the offhand promise, or the odd rule in a moment that has its own present-tense reason to exist. If the plant only exists to serve page ninety, readers feel the machinery. If it never returns, it was clutter dressed as texture.
Payoffs should reframe the plant, not merely repeat it. The best returns change cost: the joke becomes a wound, the gift becomes a trap, the skill becomes the only exit. Align payoffs with act turns and midpoints when you can, so structure and surprise shake hands instead of competing for attention on the page.
Audit in both directions. Highlight plants without payoffs and payoffs that arrive unprepared. Table reads expose forgotten plants when nobody remembers the setup; coverage often flags coincidences that needed an earlier seed. Show-don't-tell pairs naturally here -- dramatize the seed in behavior, then let the return land without a speech explaining the trick.
Early enough that the payoff feels prepared, late enough that the plant still has present-scene purpose. Orphan setups and miracle saves both break trust.
Yes -- a promise, a rule, or a throwaway boast can plant. Just make sure it is memorable in behavior or conflict, not only in a mute line of chatter.
Closely related. Chekhov's gun is the classic plant/payoff warning: do not load a gun in act one unless it matters later -- and do not fire a gun you never showed.
As many as you can pay off cleanly. A few sharp loops beat a dozen forgotten seeds that only the writer still remembers in notes.
