Law says that they should be leaving soon. He wants to take her with him and borrow her ability.

"Oh, on a date? I'm so happy." Law ignores her and heads off somewhere.

Caesar and Luffy are fighting. Luffy inhales some gas. The subordinates say that he'll die instantly, but he's fine.

It's revealed that [Luffy's relative immunity] is thanks to Magellan, but Caesar says not to lump him in the same category as Magellan.

Luffy attacks with JET Mace (haki enhanced "Bell").

Under Caesar's orders, the slime wraps around Luffy and creates a giant explosion.

Luffy's fine and attacks again, this time with Stamp.

He catches Caesar again, but then collapses in pain and loses consciousness.

Law and Monet.

Law is suddenly in pain.

Law: "Who's over there!?"
