Jadon had the great misfortune to get possessed by Cinder, a parasite-type demon, which greatly reduced his own humanity. He was briefly together with Alya before Cin killed her. When Ecaterine Kemp started to show interest in him he was first worried (read: hysteric) over what kind of harm Cin could do to her.
