NJ did everything in that awful apocalypse script to destroy Lu & Ces's relationship. He spent 15 years researching the Borgias, so he knew they were bonded and loyal to each til the end of their lives. Ces even risked his life from prison in Spain to write coded letters to her and she was devastated by his death. Maybe NJ wrote that script as a parody, but since he's kept quiet about his intentions, we can only speculate.
