Dr. Michael Stone of Columbia University has created a scale to measure the severity of evil acts. The more heinous the crime-and the more rational the criminal-the higher the killer is ranked on the scale. He has named it 'Échelle de Cruauté', or 'The Scale of Evil' - sequel to Folie a Deux (Hannibal/Will)

A missed chance for manipulation on Lecter's part opens up an opportunity not previously regarded, setting his design for Will Graham on a different but no less twisted path. The reality of a companion. Realising that Will's capacity for love is greater than his capacity for hate, Hannibal thought humorously, is just something he would have to live with. (Hannibal/Will)
