All Yamato has to do is say she knows where the last RP is, and if it’s a crazy island where danger is likely rather than possible, Luffy will still want to go there. Beyond that, and I can’t believe I have to keep bringing this up, he NEEDS to find that red rock before he can even think about going to Laugh Tale. Someone needs to be brave enough to record a video of themselves looking me right in the eye so they can say they honestly believe that the main character will reject the one - the ONLY - person who can help him out. He’s gotten 90 percent of the way on his own, and the author clearly wants Yamato to be the missing 10 percent.
