You have a main plot. You have, somewhere in chapter eight, what you have been calling a subplot. It is mostly your B character doing things.
The misdiagnosisThe misdiagnosis is that subplots are color. Texture. Something to keep the reader interested.
The real diagnosisA subplot is not color. A subplot is a counter-melody. It speaks back to the main plot. It throws the main plot's question into a different light. If your subplot is not arguing with your main plot, it is filler with a name.
What A Subplot Owes The Main Plot
| Owes | Looks Like | If Missing |
|---|---|---|
| A thematic echo | Different problem, same question | Subplot feels detached |
| A scheduling impact | Forces choices in main plot timing | Subplot feels skippable |
| A character mirror | Makes the protagonist's blind spot visible | Subplot feels decorative |
| A climax convergence | Subplot resolves alongside main | Subplot feels orphaned |
Three Subplot Questions
- What is the central question of my main plot?
- What is the same question, asked differently, in my subplot?
- At the climax, do both questions get answered at once?
A subplot that does not argue with the main plot is a side door to nowhere with the lights left on.
Map your subplot beat by beat against your main plot. If you cannot draw the parallel, the subplot is borrowed weight.
The dare (not assignment)Write the central question of your main plot in one sentence. Write the same question, in your subplot's language, in one sentence. If they are not the same question, you have your repair.
