Basics to Know About Supporting Characters
Every writer has different ways of creating characters or choosing which details go in a character background. Supporting characters serve a role in your story, so follow these basics as you work them into the story scenes.
- Make them interesting. Give them imperfections that reflect their human weaknesses. They don’t need to be likeable as long as they are interesting. Opposition supporting characters push your sleuth’s boundaries. As individual characters, you will side-step time-worn archetypes to make the situation unique…interesting.
- Give them a unique name. Start each character name with a different alphabet letter. If your sleuth is named John, that’s it for J. No Jim as a secondary character. Using this simple tactic, helps readers identify each character and remember them when they appear again pages later.
- Give them unique dialogue. The way a character speaks is part of their differentiation in your story. Add pet phrases and words each character uses in your character background. You’ll remember these phrases as you create dialogue.
- Make them surprising. Just as you want your story to be unpredictable, give supporting characters about faces and “out of character” actions. You’ll add depth to the character and give the reader another reason to keep reading.
- Keep them in context. Supporting characters are just that. They support. They support the story. They act in relation to your sleuth and to suspects. Their actions, dialogue, thoughts and opinions must move the story forward. It’s easy to fall in love with a supporting character and give them more space than necessary. Always check that your supporting character is moving the story forward.
