Caesar Clown, incensed with the humiliation that his prisoners escaped and are inside his lab, orders the passage between building A and B to be closed and Shinokuni to be let in to kill the intruders. Vergo, however decided to take care of them himself. Chopper, who was eavesdropping snuck out and tries to find his way to the children within the labyrinth that is the lab. Luffy, Smoker and Law were the first to cross the gate before the alarm sounded, indicating the gate is beginning to close. Tashigi instead heard the alarm and quickly ordered the G-5 marines to let the Straw Hats go and hurry towards the closing gate. When a wall was blown up in building A, Shinokuni flows in petrifying some marines while the rest hasten their escape. The Straw Hats and most of the marines got through the gate safety but a few stayed behind to help Tashigi across before the gate closes, losing themselves to the poison gas while their captain watches in horror. Caesar, angered that they survived, promised that no one will escape this lab alive.
