When Roma and Juliette storm into Zhang Gutai’s apartment in search of Qi Ren, the house is flooded with water. They find Paul Dexter lying unconscious on the floor. Juliette wakes him, and he claims that the Larkspur sent him on business and that the monster attacked him. As Juliette helps him up, he stabs her with a syringe containing the vaccine for the madness. He tells her that he loves her and wants to save her. Juliette realizes that he is, in fact, the Larkspur.

Paul admits that he is the one causing the madness. He imported the insects from England, hoping to spread the madness throughout the city and then profit from selling the vaccine he created. He tried to infect Zhang Gutai first but accidentally infected his assistant instead. He was shocked when Qi Ren turned into a monster made from the insects, but his plan still worked because the monster infected people all over the city. Paul offers to work with the Scarlet Gang to distribute the vaccine, but Juliette refuses. The monster appears, and Paul gives it a dose from a syringe that causes Qi Ren to become stuck as a monster.
