In the 604th One Piece episode the heroes seal the gas-filled breach, Law reveals the escape route lies in Building R, and the marines reluctantly fall in line as Smoker sets out to face Vergo.
Summary
The breach left when the group barreled into the lab lets Shinokuni pour inside, so the G-5 marines scramble to plug it with planks while the gas blankets the island. Brook turns to spirit form to scout outside, reporting that a single step beyond the wall would mean death.
Recovered, the marines raise their weapons to arrest the Straw Hats. Nami forces Law to swap her and Sanji back, then punches Sanji for ogling her body. Law warns there are only two hours to flee and that the lone safe exit, R-66, sits in Building R. The marines balk until Smoker repeats the order, after which he sends Tashigi to lead the men and save the children while he goes after Vergo. Realizing the cage holds no petrified corpses and the outside marines are gone, Caesar grasps that his prisoners escaped, and Zoro reminds Luffy not to drop his guard in the New World as he charges Caesar's satyrs.
Key Events
The G-5 marines seal the hole that was letting Shinokuni into the lab. Brook scouts the lethal exterior in soul form. Law returns Nami and Sanji to their own bodies and reveals the R-66 passage in Building R as the only escape, with two hours before it is unusable. Smoker compels the marines to comply, then assigns Tashigi to command them and rescue the children while he leaves to confront Vergo. Caesar realizes his captives have broken free. Luffy plows ahead toward Caesar after Zoro's warning.
Notes
Adapting parts of Chapters 678 and 679, this Punk Hazard Arc episode debuts Luffy's Gomu Gomu no UFO technique. Where the manga has Law simply name the R-66 gate, the anime has him lay out the facility's layout in detail. It also inserts a brief scene of Luffy asking Robin for a favor.
