Which is fine and dandy, but Big Mom isn’t some easily neutralized threat that Sanji could or should have brushed off in the interest of saving the citizens of WCI. There’s no reason why he couldn’t have made that cake taste delicious to entice her, while also including some poison or other ingredient that could have knocked her ass out. Why did he spend the whole timeskip learning Attack Cuisine from the okamas if the only thing he was gonna do with it is restore a Yonko to full health?? If he’s a man of the people, why feed the rampaging queen a tasty cake that doesn’t hurt her in any way??
