Zeff and Sanji's Dream! The Illusory All Blue!

With Zeff held captive by Ghin, Sanji has no choice but to take Pearl's hits. He reveals that he worked on a cruise ship that Zeff attacked, and when a storm hit, the two were the only survivors. Zeff sacrificed his leg to save Sanji and gave Sanji food, as both shared the same dream of finding the legendary ocean, All Blue (supposedly the only place in the world all four seas (North, South, East and West) meet and where the seas' respective aquatic species also meet). No longer able to fight with his legs and be a pirate, Zeff founded the Baratie. Sanji reveals that he will defend the Baratie with his life, and Luffy responds by attacking the ship's porch with Gum Gum Axe.
