Upon investigating the grave of a woman with a striking resemblance to Queen Coco Rose, Victorique manages to put together the truth behind her mysterious demise. The truth of the Coco Rose case and the disappearance of Nicole Lulu is made clear, and Albert frees Victorique when she is unable to conclusively identify the murderer. On the way home to the Academy, Victorique and Kujo encounter a seemingly ordinary couple who are actually the still-living Coco Rose and her son fathered by Leviathan. Cordelia watches over them as they arrive home, and is soon joined by Brian and then a man who seems to be Brian's twin.
