They succeed on their mission but Sakuma is intrigued when Gordon says this was the second time the military police went there. Sakuma then realizes that this plot was contrived by Muto to fail so as to hide his own failure investigating Gordon. Sakuma also realizes that Yuki discovered Muto's plan and used this event to blackmail him to collaborate with D-Agency, hoping to receive more funds from the Army.
