Haha, indeed. It seems he's going against all the strong guys, Vergo and now Dofla, but he doesn't really have much of a chance. And now that he's sailing away with Nami, he might not get any fights during Dressrosa.
Depending on what happens between Law and Dof, Sanji may be getting a visit from some more Dressrosa assassins... ya know? Like where the hell is this Pica guy? Diamante and Trebol are at the coliseum, so Pica has to be involved somewhere in this whole... fiasco.
Also Sanji might have to deal with some marines, so who knows?!
