When should a writer use multiple plotlines in the same story?

Question

a if they are loosely related to each other

b if they share characters and a setting

c if they are in the same genre

d if they are unrelated to each other

Answer 1

A writer should consider using multiple plotlines in the same story primarily when:

b if they share characters and a setting

Using multiple plotlines that share characters and a setting can create a richer narrative, allowing for deeper exploration of themes, character development, and relational dynamics. While loosely related plotlines (option a) can work, the strongest integration often comes from shared elements that enhance the overall coherence and engagement of the story.
