its a tiny spoiler but i wish they had animated and included in that episode the reaction of marco to this treason.

seems its all over for the whitebeard pirates i guess, the pacafistas seem dominant but you have to wonder with marco and whitebeard being both not in combat why didnt they turn around and just smash the pacafistas like flies then resume the frontal assault.... i always assumed that the power of some men in one piece was proportional to the damage they could do, eg a man with a rubber body can only take out one opponent at a time and therefore his power is relativley limited, but a man who can turn himself into lightening or fire could perhaps take out an entire army or kingdom at one time thus making him much more powerfull in the grand scheme of things, even if the rubber man would defeat him in single combat... but they have never displayed this kind of thinking in the show yet....
