Yeah, Ace Sabo and Vivi are the three characters not on the crew who don't break the pattern if something is only for nakama. If something was only done for Luffy, Zoro, Nami, Ussop, Sanji, Chopper, Robin, Franky, Brook, Jinbei, Ace, Sabo, and Vivi, it might as well be only crewmembers, and anyone else included should raise some eyebrows. My only holdup is that Oda could have just been doing all the nakama first, and now that he finished them, he's moving on to other characters. We could just as easily see Law or Shanks next time and then it's meaningless.
