Understanding Subplots: The Key to Storytelling

I’ve had lots of questions and about plotting stories, and my articles on plot and structure continue to be among my most read posts.

What is a Subplot?

A subplot is a secondary storyline which runs alongside the main plot. It often involves supporting characters, additional conflicts, or personal struggles that relate directly or indirectly to the protagonist’s journey. Some of the best subplots connect to the main narrative, either by reinforcing the theme, revealing character traits, or influencing the main plot’s outcome.

Why We Need Subplots?

Whether you are writing scripts, short stories or novels, having multiple plot strands creates a necessary expansion of the main themes and layers your stories. Subplots add depth, complexity, and emotional resonance to a story. They transform a simple narrative into a layered experience that feels more realistic and engaging. Understanding how and why to use them strengthens your writing.

Subplots Add Depth to Characters

One of the greatest strengths of subplots is their ability to develop characters beyond the main storyline. The main plot often focuses on a specific external goal: solving a mystery, defeating an antagonist, or achieving a dream. Subplots, however, often explore the internal lives of characters: their relationships, fears, and motivations. This creates intrigue and insights for the reader, which might be missed through the main plot line.

Creating More Realistic Worlds

Real life rarely follows a single narrative thread. People juggle relationships, responsibilities, and individual struggles. Subplots highlight this layering effect by weaving multiple storylines together. This creates a world which feels more realistic. Supporting characters also show their own motivations and story arcs rather than existing solely to support the protagonist. This creates a richer, more immersive experience for the reader.

Subplots Strengthen Themes

Subplots are powerful tools for reinforcing the central themes of a story. A well-designed subplot often mirrors, contrasts, or adds complications to the central plot. If the main plot explores trust, a subplot might show a different character grappling with betrayal in a different context. These variations allow readers to view themes from multiple angles, making the story feel more authentic.

Change of Pace

A single storyline moving at full intensity from beginning to end can become exhausting for readers. Bringing in subplots shift the focus and builds gradual tension, creating breathing space between key points in the plot. They can also act as narrative bridges which keep readers engaged, while the main plot builds toward a pivotal turning point.

Subplots Drive the Main Plot Forward

Although subplots are secondary, they often have direct consequences for the main storyline. A subplot might influence a character’s choices during a critical moment, or reveal information which changes the direction of the main conflict. When subplots intersect with the main narrative, the story feels more interconnected.

Some Examples in Films

If you’ve ever watched the film, Crash, you’ll see how well subplots are used to increase tension and keep the viewer hooked. Set in LA over several days, we see the stories of different characters interweaving. Its impact is intense. Layering is important, and an interweaving of plot and subplot creates a richer, more diverse experience.

In the film, Shawshank Redemption, the role of Brooks as Red’s negative mentor, tricking the viewer into expecting Red will follow the same path towards destruction.

What about Bilbo Baggins, who saves the dwarves from the spiders in The Hobbit. Baggins is a good example of creating conflict through a subplot to illustrate growth in a character.

The Power of Character-Driven Stories

One of the questions I’m most frequently asked as a writer is, ‘do you focus on plot or character?’ I predominantly write thrillers, so character is particularly important and often drives the story line (the plot). Jana in Take Me to the Castle and Leisl in Dead Drop are strong female protagonists. Their thoughts, lives and actions drive the plot.

It works well for short stories, particularly given the brevity of the craft and the constraints of needing to hook a reader quickly, drawing them into a story. When the reader is engaged with the character, they are more likely to engage with the story and understand the motives driving the character’s decisions and actions.

When a reader knows what a character has experienced and understands their weaknesses and specific character traits, the story makes more sense and the reader wants to go on the journey with them.

Who your characters are is much more intriguing than what they do in a character driven story. We don’t engage with perfection as readers, we engage with vulnerability. Vulnerability leads to trust and connection.

It works with fictional characters in the same way as in real life. The writer’s job is to make the reader care, and the most effective way to do this is to highlight a character’s fears, vulnerabilities, and internal conflicts. I’ve written more about this in other posts on plot writing here and here, as well as on the narrative arc.

My Writing Journey: From Novels to Short Stories

WordPress sends these milestone reminders, and it’s often a good time to take stock and realise how far you’ve come as a writer. I began writing my debut novel, Take Me to the Castle, in 2007. It was published in 2012 and won The People’s Book Awards in 2013. I began writing short stories with several going on to be published in literary journals. Some won writing competitions and I was inspired by so many other writers and their stories…Alice Munro, Lydia Davis, Hilary Mantel, David Gaffney, Raymond Carver, Franz Kafka, Anton Chekhov, Ernest Hemingway.

It’s been a journey! Eight books (including two novels, two short stories and work in four anthologies) later and I still get a buzz from writing down the first words of a story, a poem, or a novel. I don’t know where the last 12 years have gone, but it’s been quite a journey. Writing, the grit required to keep going and hone your craft, along with the journey to publication, requires motivation and determination. It demands new learning and a level of discipline, but it’s also a lot of fun. The creativity, the process, it’s all part of the draw to write.

I’ve learned that you will always surprise yourself, and others. You’ll never quite know where you are going. This applies even to the most tightly planned plot! You can read more about planning, plot and structure in these posts:

What’s Your First Draft Like? Author Interview

I get asked lots of questions on where I find my ideas and how I write. It’s different for poetry, short stories, flash fiction and novels. Novel writing is a marathon, not a sprint, but it also allows you more space for a story to unfold. Short stories and flash fiction, in particular, are less forgiving and no word can be wasted. You need to grab your reader in just a few hundred words, or more, or less!

I love writing. I love it as much now as I did 12 years ago. Blogging has also been a really helpful way of sharing my journey and what I’ve learned. I’ve been able to encourage new writers, connect with readers, network with people, interview authors and be interviewed. Thanks for joining me on the journey, whether you’ve just arrived (welcome!) or if you’ve been here a while. Drop any questions in the comments.
