A scene can go on for as long as the story needs it to. That means the narrator can “continue” the scene by writing more, and the players can make additional moves. A scene only ends once all the players “end their turn” by choosing a dramatic outcome for the scene.
If you are done describing your character’s actions for the current scene, you should end your turn. You can use “commentary” to coordinate with your narrator and your fellow players.
We will work on ways to make this clearer, thanks!
