Cut to 4th floor, Who's Who Vs. Jinbei. Who's Who uses “Geppou” to jump into the air. Jinbe asks him if the reason he has grudge against Luffy is becouse he ate the “Gomu Gomu no Mi”. Who's Who replies that he has grudge against “Akagami Shanks” who took the “Gomu Gomu no Mi” from him.
Then Who's Who shoots a “Gagan” to Jinbe. He blocks it with Armament Haki but the attack damages Jinbe in his arm. Who's Who continues talking. He says Luffy inherits both the “Gomu Gomu no Mi” and the straw hat from Shanks, so naturally he'd want Luffy dead too. Who's Who shoots now a rain of "Gagan" down at Jinbe. He manages to dodge Who's Who attack while all “Gagan” arrive to the 3rd floor.
