Relationship Thesaurus Entry: Twins

Successful stories are driven by authentic and interesting characters, so it’s important to craft them carefully. But characters don’t usually exist in a vacuum; throughout the course of your story, they’ll live, work, play, and fight with other cast members. Some of those relationships are positive and supportive, pushing the protagonist to positive growth and helping them achieve their goals. Other relationships do exactly the opposite, derailing your character’s confidence and self-worth or they cause friction and conflict that leads to fallout and disruption. Many relationships hover somewhere in the middle. A balanced story will require a mix of these dynamics.

The purpose of this thesaurus is to encourage you to explore the kinds of relationships that might be good for your story and figure out what each might look like. Think about what a character needs (good and bad), and build a network of connections for him or her that will challenge them, showcase their innermost qualities, and bind readers to their relationship trials and triumphs.

Description: Twins—identical and fraternal—have a unique sibling dynamic. While birth order can often help determine personality and determine family dynamics, the same rules don’t apply to children born only minutes apart. Their identical age often means they share the same space at home, are given the same rules, are in the same grades at school, often have the same friends. Despite being individual and different people, a twin’s identity is often partially wrapped up with their sibling’s.

Relationship Dynamics
Each relationship is different, depending on the people involved, their history together, their individual personalities, and a host of factors. Here are some common dynamics—healthy, and not so much—that can accompany this relationship. Use the ideas that suit your story and work best for your characters to bring about and/or resolve the necessary conflict.

Being best friends with one’s twin
Knowing that the twin always has your back
Being a companion or ally to help one’s twin navigate the difficult stages of life
Intuiting a twin’s emotional state or physical sensations on a deeper level (sensing when they’re in danger, feeling pain when they feel pain, etc.)
Knowing one’s twin intimately and being able to offer meaningful and even life-saving advice
Recognizing and valuing differences as a way of embracing individuality
Recognizing the difficulties of being a twin and trying to make things easier for one’s sibling
Being in frequent communication, even as adults who are physically separated
Engaging in various degrees of sibling rivalry
Vying for people’s attention
Other people’s expectations creating insecurity or frustration (expecting twins to be alike in personality or aptitudes, etc.)
