A secondary plot that comments on or pressures the main line (often relationships). At macro scale, structure and pacing decide when readers breathe and when pressure spikes.

As a concept, it names a force readers feel even when they never use the word.

Why it matters

B-story names a structural or pacing move — use it to diagnose sag, turns, and reader energy across scenes and acts.

Common pitfalls

Using b-story as a label without checking whether the page actually performs the job.
Letting b-story crowd out scene goal, conflict, or change at the end of the unit.

Example only

Readers feel b-story when stakes tighten after the ally refuses to help.
