Kogoro views Conan as a freeloader who constantly gets underfoot and never fails to insinuate himself at cases, "interfere" with the scene, and pipe up with childish observations that consistently ruin Kogoro's deductions.

As they are leaving, Shinichi witnesses a suspicious exchange between an unknown business man and in a secluded area by the ferris wheel.
