Subplot

A subplot is a secondary storyline that runs alongside the main plot. It has its own want, obstacle and turning points, but it is smaller in scope than the central conflict, and it usually crosses the main line at key moments to add pressure, contrast or meaning.

What a subplot does for a story

A story that follows one line only can feel thin on a long page count. A subplot gives the reader a second thread to follow and lets the writer show the central conflict from another side.

Subplots do several jobs:

  • Pressure. A subplot can make the main character's choice harder by giving them something else to lose.
  • Contrast. A parallel line can show what the protagonist might become or avoid, the way a second couple's relationship can reflect the first.
  • Pacing. Moving to a lighter or slower thread gives the reader relief between intense stretches of the main plot. See pacing.
  • Depth for secondary characters. A character with a subplot of their own reads as a person with a life, not a function.

Main plot compared with subplot

Main plot Subplot
Question it asks The story's central question A smaller question tied to a secondary want
Scope Runs from opening to ending Often enters later and may resolve before the ending
What the ending depends on The final resolution Usually nothing, but it shapes how the ending feels
If you remove it The story collapses The story still stands, with less depth
Typical weight Most of the scenes A smaller share of the scenes

The simplest test is subtraction. Remove the line from the story: if the central question is gone, it was the plot; if the question survives but the book feels flatter, it was a subplot.

The word is sometimes confused with a B plot, a term borrowed from screenwriting for the second-most-prominent storyline. In practice a B plot is the biggest subplot.

Recognizable examples

Shakespeare, King Lear (c. 1606). The main plot follows Lear dividing his kingdom and being betrayed by two of his daughters. The Earl of Gloucester and his sons, Edgar and Edmund, form a second story in which a father trusts the wrong son and casts out the loyal one. The two lines echo each other, so the subplot shows the same mistake from another angle.

Jane Austen, Pride and Prejudice (1813). Elizabeth Bennet and Mr. Darcy are the main plot. Alongside it run Jane Bennet's courtship with Mr. Bingley and Lydia Bennet's elopement with Mr. Wickham. Both subplots feed the central line: Darcy's part in separating Jane and Bingley feeds Elizabeth's prejudice against him, and his part in resolving Lydia's elopement changes how she sees him.

A constructed example. In a detective novel the main plot is the hunt for a killer. A subplot follows the detective's strained relationship with a daughter who has stopped answering calls. It matters when the case forces the detective to choose between a late-night stakeout and her school play.

How to write a subplot

Give it its own want. A subplot is a story, not an event. Its character should want something, meet an obstacle and reach a change, however small.

Tie it to the main line. The strongest subplots press on the central choice: they complicate it, mirror it or raise its cost. Cross the lines in scenes, not just in the outline, so a development in one changes the other.

Plant it early, resolve it near the main ending. A subplot that appears from nowhere in the final third reads as an interruption. One that closes long before or after the main climax leaves the ending feeling unfinished.

Match the weight to the want. The scenes a subplot gets tell the reader how much it matters. A thread with two scenes cannot carry a large emotional payoff.

Let it earn its place. Ask what the story loses if the subplot goes. If the answer is only "length," cut it.

Common mistakes

  • A subplot with no link to the main line. It reads as a detour. Give it a point of contact, in cause, theme or character.
  • Too many threads. Each new line takes scenes from the others. Stories with many threads usually have clear priority among them.
  • Dropping a thread without closing it. A subplot the reader cares about needs an ending, even a quiet one. An abandoned thread feels like a plot hole.
  • Resolving the subplot by coincidence. If it ends because the main plot happens to sweep it up, the reader sees the join. Let a character's choice close it.
  • Making the subplot the real story. If readers care more about the secondary line, the book may be mis-framed; check which question the ending answers.

Tracking subplots in Writer Studio

A subplot is easy to lose track of across a long draft: it appears in chapter three, vanishes, and returns two hundred pages later. In Writer Studio, a plotline in the Book Wiki is an ordered list of the scenes that carry a thread, with a status of Introduced, Developed, Paused or Resolved. You add a scene to one or more plotlines from the scene's Properties panel, so one scene can belong to both the main plot and a subplot.

Reading the subplot's scene list shows at a glance how long it has gone untouched and whether it has reached a scene that closes it. Download Writer Studio, free and local-first.
