While Chuuya and Fyodor were stuck in the flooding cell room, Dazai led Sigma to one of Merusault's surveillance control rooms. Being stuck with Dazai was not on Sigma's agenda, and he was still pretty frustrated about being chosen as Dazai's 'prop' for his escape.
"Don't open that door! It leads to the surveillance room! Do you want to get shot?!" Sigma quickly protested, watching helplessly as Dazai nonchalantly punched in numbers and letters. This was ridiculous! They were supposed to be escaping.
"I already opened it!" Dazai grins. Sigma watches in horror as the pad turn to green, the door which he was standing in front of opening up.
However, instead of being greeted with gunfire, the guards were all slumped over, as if they were sleeping.
