When most people think about storytelling, they think about the main plot—the big quest, the ultimate goal, the central conflict. But any truly rich, memorable story is made up of more than just that single thread. That’s where subplots come in, and they’re where the real magic often happens.
A good subplot adds depth, complexity, and emotional resonance to your narrative. It can develop side characters, deepen worldbuilding, or highlight different facets of your protagonist. Think of subplots like harmonies in a song. The melody might carry the tune, but those harmonies are what give it power and richness.
So how do you create a subplot that doesn’t just feel like filler?
1. Tie It to the Main Theme
Your subplot should echo or contrast the theme of your main plot. If your story is about power and responsibility, maybe your subplot explores what happens when someone avoids responsibility—or seizes power recklessly.
2. Use It to Develop Character
A romantic subplot can challenge a stoic warrior to open up. A friendship subplot might force your villain to reconsider their choices. Subplots are fantastic for showing growth or highlighting a character’s flaws in a different light.
3. Let It Intersect the Main Plot
The strongest subplots don’t run parallel—they collide. Maybe your hero’s best friend is caught in a political scandal that directly impacts the main quest. Maybe a love interest’s betrayal sets up the final battle. Let them matter.
4. Don’t Let It Drag
If your subplot starts to overtake the main narrative—or worse, wander aimlessly—it’s time to trim. A subplot should feel like it’s pulling the story forward, not weighing it down.
5. Resolve It With Intention
A satisfying subplot has a beginning, middle, and end. It may not get as much page time as your primary arc, but it deserves a resolution. Even an open-ended one—if it’s purposeful—feels more satisfying than one that simply vanishes.
Subplots are where stories become layered. Where readers fall in love with your secondary characters. Where emotional gut-punches live. Don’t treat them as an afterthought—treat them as an opportunity.
