They claimed that they didn't kidnap Cuthbert Calculus, and Cartoffoli drives them off leaving the protagonists behind. Somehow, Tintin realized the Calculus was transported by the back seat, and was about to trasnport Calculus to Syldivia by plane. Tintin tried to interviene, but Boldoff the pilot managed to escape from him. The agents were then in an unknown fate after they flew across the Bordurian border.
