Sometimes certain effects, bonuses, or conditions state that they last until the end of the scene. At the GM’s discretion, a scene continues until the current narrative situation has played out. A chase scene might end when the PCs have caught their quarry or when they’ve escaped pursuit. A battle scene usually ends when one side has fled, surrendered, or been entirely defeated. If there’s uncertainty about when a scene is considered to be over, throw it to the table and see what the players think makes sense. You don’t have to linger in a scene after the most engaging actions and interactions have occurred. If you want to play out their implications or process the emotions but the heat of the moment has passed, that aftermath can take place in its own scene.
