A turning point (also known as a “plot turn” or “plot point”) changes the direction of the story, through an action or a revelation. The protagonist was going one direction, and an event takes place or information is revealed, and the protagonist is now on a different trajectory. Major turning points are often recognized in popular story structures. “Crossing the Threshold” in the Hero’s Journey and “All is Lost” in Save the Cat are both examples of major turning points. And let’s not forget, the biggest turning point of all, the climax, turns the story from conflict to resolution.

Previously, I discussed how relationship plotlines have the same elements as external plotlines: arcs, goals, antagonists, conflicts, and consequences. They just manifest a little differently.

This is also true with turning points. Relationship plots (whether they be between allies, love interests, or enemies) need turns as well. So, let’s go over their critical components.
