The other night, my players completed the Nocturne scenario, and did so by walking through the door to Dream Lausanne, finding the Scroll of the Head in Edgar's taxidermy shop, and despite some pretty obvious hints, decided that "hell with it, we have the scroll. This is all just too weird. Let's get the hell out of here!".
So...how does the fact that they completely avoided meeting the Jigsaw Prince affect the campaign later on, if at all? I still have yet to stage the subsequent encounter on the train, so there is that. Obviously, poor Edgar is doomed, but other than that, does missing the encounter impact things?
