I have to admit, I liked the chapter, but it did feel slightly like an asspull that King Baum's feelings for his girlfriend overruled Mama's control.
I have no problem with the Zeus bit though, he's always been portrayed as a bit dim and technically, he hasn't disobeyed a direct order yet, like King Baum. I doubt he will stick with the SH's though, he's still made from Mama's soul after all, but he'll have a part to play in the escape I'm sure. It will be strange if he does ignore Mama completely though, if she gives him a direct order, he technically should listen.
Sooo Mama's attack with the Bicorne was called 'Spear of Elbaf'.. Wut? Is the sword from Elbaf, did I miss something?
