S18:E19: 5 Tips for Writing Subplots That Strengthen Your Main Plot

How do you write subplots without ending up with a story that feels like a collection of disconnected pieces? In this episode, I explore how to write subplots that strengthen the main plot by integrating secondary characters, conflicts, relationships, and themes into one cohesive story.

Subplots can add richness, complexity, and depth. But they aren't necessarily the most useful way to think about story.

The strongest subplots grow out of the same character goals, conflicts, relationships, and thematic questions that shape the main plot—until they become difficult to separate from the story's larger structural throughline.

In this episode, we'll look at:

• What a subplot actually is—and how it differs from the main plot • The difference between subplots and multiple plotlines • The three central throughlines of external conflict, relational conflict, and internal conflict • Four structural sources from which subplots naturally arise • How supporting-character goals create secondary conflicts • Why minor antagonists and their goals can deepen the main plot • How to test whether a subplot is truly necessary by looking at the Climax • Why every subplot should also contribute to the story's theme • How color coding can help writers organize complex plotlines • How to combine subplot material with main-plot scenes for greater cohesion

Ultimately, the goal isn't to pile more storylines into your novel. What you want to do is create a story in which every thread feels as though it belongs to the same larger pattern.

Or, to put it a little more cheekily:

There are no subplots, just plots.
