I mourn the death of zorro's ambition. As noted by Mihawk, he has just chosen to mere fodder/ supporting cast and put his ambition under luffy's. For a man with ability, talent and such great initial goals, that's quite sad (I don't see how the ambition of helping another person to be a king can be compared to the ambition of being the best.
It also means he has effectively given up the promise to his dead (might have been) girlfriend.
Btw for those who were complaining about how the last few chapters have just been short panels of disparate scenes showing what each member was doing, it's likely the next few chapters at least after the break will be the same. In fact it's likely to be more otherwise he won't be able to show how much has happened within the 2 year break. personally I don't mind, but just to get people mentally prepared; or to start worrying
Well, unless he somehow adds in a short summary page full of words.
