A suffusion of yellow
ah okay, as I define turns I'd include the GM setting up the scene in the first place as a Turn that the other players then respond to.If one player takes four moves and the others take none, and the scene is now done, we did not "take turns". There is no mechanism nor rule that transfers or sets who goes next. The GM should make sure everyone gets equal spotlight, but since PbtA games you can easily split the party that doesn't always mean within a particular scene.
Even in a GM-less game there is a first Turn that sets the scene for further interactions
