3.2 Supporting characters

Types of Supporting Characters

Supporting characters do the heavy lifting in TV writing. They're the ones who create conflict, deepen the protagonist, reinforce themes, and make the world of a show feel real. A protagonist alone on screen is just a person talking to themselves. Supporting characters give them something to push against, lean on, or run from.

The key distinction: every supporting character needs a reason to exist in the story. That reason might shift over time, but if you can't articulate what a character does for the narrative, they probably shouldn't be there.

Sidekicks and Best Friends

• Provide emotional support and companionship to the protagonist
• Serve as a sounding board for the main character's thoughts and decisions, giving the audience a window into the protagonist's internal world
• Can offer comic relief or contrast to the protagonist's personality (Watson grounds and humanizes Sherlock Holmes)
• Often carry their own subplot that parallels or complements the main storyline

Antagonists and Villains

• Create the conflict and obstacles the protagonist needs to overcome
• Range from morally complex anti-heroes to outright evil characters
• Drive the plot forward by directly challenging the main character's goals and beliefs
• Can evolve over time, sometimes becoming allies or earning redemption arcs (Jaime Lannister in Game of Thrones shifts from villain to tragic hero across several seasons)

Love Interests

• Introduce romantic subplots and raise the emotional stakes
• Create tension through love triangles, forbidden relationships, or competing priorities
• Often have their own character arcs that intertwine with the protagonist's journey
• At their best, they challenge the main character's growth rather than just supporting it (Pam Beesly in The Office has a full arc independent of Jim's)

Mentors and Guides

• Provide wisdom, guidance, and skills the protagonist needs to learn
• Often possess knowledge or experience the main character lacks
• Gain depth when they have their own flaws or past failures
• May sacrifice themselves to further the protagonist's journey (Mr. Miyagi in The Karate Kid)

Comic Relief Characters

• Lighten the mood and provide moments of levity during tense situations
• Often built around exaggerated personality traits or quirks
• Can offer a different, sometimes surprisingly insightful perspective on serious events
• The best ones have hidden depths revealed over time (Chandler Bing in Friends uses humor to mask insecurity, which becomes a real character thread)

Functions of Supporting Characters

Beyond their type, every supporting character serves one or more narrative functions. A single character can fill multiple functions at once, and their primary function can shift across episodes or seasons.

Plot Advancement

• Introduce new information or plot twists through their actions or dialogue
• Create obstacles or provide assistance that drives the story forward
• Initiate subplots that intersect with the main storyline
• Serve as catalysts for major turning points in the narrative

Character Development

This is one of the most important functions. Supporting characters act as mirrors and foils for the protagonist.

• Reflect different aspects of the protagonist's personality or journey
• Challenge the main character's beliefs or decisions, prompting growth
• Provide contrasting viewpoints that enrich the story's themes
• Reveal hidden depths of the protagonist through their interactions

Thematic Reinforcement

• Embody different facets of the show's central themes or messages
• Offer diverse perspectives on moral dilemmas or social issues the series explores
• Demonstrate consequences of choices related to the show's thematic elements
• Create parallels or contrasts that highlight the story's underlying ideas

World-Building

• Represent different social groups, professions, or cultures within the show's universe
• Provide exposition about the setting's history, rules, or customs in a natural way
• Introduce new locations or aspects of the world through their backgrounds or storylines
• Show how the show's world affects people beyond just the protagonist

Creating Memorable Supporting Characters

A forgettable supporting character is a wasted opportunity. The difference between a placeholder and a fan favorite usually comes down to specificity: specific traits, specific history, specific wants.

Distinct Personality Traits

• Develop unique quirks, habits, or mannerisms that set each character apart
• Create a consistent voice and worldview for each supporter
• Balance strengths and flaws to make characters relatable and multi-dimensional
• Avoid one-dimensional stereotypes by adding unexpected elements (a tough enforcer who paints watercolors, a cheerful optimist with a ruthless competitive streak)

Unique Backstories

• Craft detailed histories that inform characters' present-day actions and motivations
• Include formative experiences or traumas that shape their worldviews
• Build connections to other characters through shared history
• Reveal backstory gradually to maintain intrigue and depth. Not everything needs to come out in the pilot.

Specific Goals and Motivations

Every supporting character should want something, and it shouldn't just be "help the protagonist."

• Establish clear objectives for each supporter, independent of the main character
• Create internal and external conflicts that drive their actions throughout the series
• Develop a hierarchy of needs and desires that influences their decision-making
• Allow goals to evolve as characters grow and face new challenges

Character Arcs for Supporters

• Design growth trajectories for key supporting characters over the course of the series
• Create opportunities for supporters to face their own challenges and learn from experiences
• Allow for both positive and negative development, including potential downfalls
• Intertwine supporting character arcs with the main storyline for cohesive narrative development

Supporting Character Dynamics

The interactions between characters form the backbone of engaging TV narratives. A show's rewatchability often comes down to how much audiences enjoy watching specific characters bounce off each other.

Relationships with Protagonists

• Develop varied dynamics ranging from loyal allies to bitter rivals
• Create moments of conflict and reconciliation to deepen relationships over time
• Use supporters to challenge or reinforce the protagonist's beliefs and actions
• Explore how these relationships evolve as both characters change

Interactions Among Supporters

This is where many shows find unexpected gold. Think about pairings the audience wouldn't predict.

• Craft unique dynamics between different supporting characters
• Develop alliances, rivalries, or romantic entanglements among the supporting cast
• Use these relationships to create subplots and add depth to the overall narrative
• Explore how supporting characters influence each other's growth and decisions

Power Dynamics and Hierarchies

• Establish clear social, professional, or familial hierarchies within the cast
• Explore how power imbalances affect character interactions and storylines
• Allow for shifts in power dynamics as characters grow or face challenges
• Use hierarchies to create tension and opportunities for character development

Writing Dialogue for Supporters

Dialogue is your primary tool for making supporting characters feel distinct. If you can cover the character names and still tell who's speaking, you're doing it right.

Voice and Speech Patterns

• Develop unique vocal characteristics for each supporter (accents, catchphrases, verbal tics)
• Create distinct vocabulary and sentence structures that reflect characters' backgrounds
• Use dialogue to reveal education levels, social status, or cultural influences
• Maintain consistency in speech patterns while allowing for growth over time

Subtext and Hidden Agendas

• Craft dialogue that conveys underlying emotions or motivations beyond surface meaning
• Use subtext to create tension or reveal character secrets gradually
• Develop scenes where characters say one thing but mean another through tone or context
• Allow supporting characters to have their own agendas that may conflict with others

Balancing Screen Time

• Allocate dialogue strategically so each supporter has meaningful contributions
• Use ensemble scenes to showcase multiple characters' voices and perspectives
• Convey character presence even with limited lines through reactions and body language
• Balance supporter dialogue with maintaining focus on the protagonist's journey

Character Consistency vs. Growth

TV is a long-form medium, which means supporting characters need to feel like the same person in episode 50 as they did in episode 1, even if they've changed significantly. That tension between consistency and growth is one of the trickiest parts of TV writing.

Maintaining Core Traits

• Identify key personality traits that define each supporting character
• Keep these core characteristics consistent throughout the series
• Use established traits as anchors for character reactions and decision-making
• Allow for subtle variations in how traits manifest in different situations

Evolution Throughout Series

• Develop gradual changes in supporters' beliefs, attitudes, or behaviors
• Create pivotal moments that challenge characters and prompt growth or regression
• Allow for shifts in relationships and dynamics as characters evolve
• Balance growth with maintaining the essence of what makes them recognizable and beloved

Supporting Characters in Different Genres

Genre shapes what supporting characters look like and how they function. The same archetype (mentor, rival, love interest) plays very differently in a sitcom versus a prestige drama.

Drama vs. Comedy Supporters

• Drama supporters often have more complex backstories and emotional depth
• Comedy supporters frequently embody exaggerated traits for humorous effect
• Dramatic supporting characters may face more severe consequences for their actions
• Comic relief characters in dramas provide necessary tonal balance

Procedural vs. Serialized Shows

• Procedural shows often feature recurring supporters with specialized roles (the forensic expert, the tech analyst) who stay relatively static
• Serialized shows allow for more extensive character arcs and relationship development over time
• Procedural supporters may have less personal storyline focus but serve crucial plot functions each episode
• Serialized supporting characters often carry intertwining storylines that span multiple episodes or seasons

Avoiding Supporting Character Pitfalls

Stereotypes and Clichés

• Identify and subvert common character tropes to create more original supporters
• Develop multifaceted characters that defy easy categorization
• Add unexpected traits or backstories to seemingly stereotypical characters
• Ensure diverse representation avoids falling into stereotypical portrayals

Underdeveloped Characters

• Provide sufficient backstory and motivation for key supporting characters
• Make sure each supporter has a clear purpose within the larger narrative
• Develop distinct personalities and voices for all recurring characters
• Allow supporting characters to grow and change over the course of the series

Overuse of Supporters

• Balance the number of supporting characters to avoid overwhelming the main plot
• Make sure each supporter has a unique function and doesn't overlap with others
• Consider combining or eliminating redundant characters to streamline the narrative
• Avoid introducing too many new supporters at once, which can confuse and fatigue viewers

Supporting Characters and Representation

Diversity in Casting

• Include characters from various racial, ethnic, and cultural backgrounds
• Represent different age groups, body types, and abilities in supporting roles
• Consider gender diversity and LGBTQ+ representation in character development
• Avoid typecasting actors based on their personal characteristics

Authentic Portrayals

• Research and consult with members of represented communities for accuracy
• Develop well-rounded characters that go beyond surface-level representation
• Avoid relying solely on a character's identity as their defining trait
• Allow diverse characters to have story arcs unrelated to their identity

Avoiding Tokenism

• Ensure diverse characters have meaningful roles and development
• Create multiple characters from underrepresented groups to avoid singular representation
• Develop relationships and interactions between diverse characters
• Avoid using marginalized characters solely as plot devices or to educate other characters

Balancing Ensemble Casts

Managing a large supporting cast is one of the hardest structural challenges in TV writing. Too many characters and the show feels scattered. Too few and the world feels thin.

Screen Time Distribution

• Allocate screen time based on characters' importance to current storylines
• Rotate focus among supporting characters to maintain audience interest
• Use subplots and B-stories to showcase different members of the ensemble
• Keep the protagonist in appropriate focus while allowing supporters to shine

Storyline Integration

• Develop interconnected plotlines that involve multiple supporting characters
• Create opportunities for unexpected character pairings and interactions
• Make sure each supporter's storyline contributes to the overall narrative arc
• Balance individual character development with advancing the main plot

Character Hierarchy

• Establish clear tiers of importance among supporting characters
• Allow for shifts in hierarchy as storylines evolve and characters develop
• Use character prominence to guide audience expectations and emotional investment
• Stay flexible enough to elevate or reduce characters' roles based on story needs and audience reception

Supporting Characters in Story Arcs

B-Plots and Subplots

• Develop secondary storylines that focus on supporting characters' journeys
• Use B-plots to explore themes complementary to the main narrative
• Create opportunities for supporting characters to intersect with the primary plot
• Balance subplot complexity with the need to maintain focus on the main story

Episode-Specific Roles

• Craft unique roles for supporters in standalone or "monster-of-the-week" episodes
• Use episodic stories to reveal new aspects of supporting characters' personalities or skills
• Create opportunities for supporters to temporarily take center stage in specific episodes
• Make sure episode-specific roles contribute to overall character development and series themes

Season-Long Character Journeys

• Design arcs for key supporters that span an entire season
• Develop gradual growth or change that parallels the protagonist's journey
• Create milestones and turning points for supporting characters throughout the season
• Allow for resolution of supporter arcs that contributes to the season's overall themes and climax
