well you know, ussop's picture is on the luffy's bounty list…but it seems like nobody notice him there especially his dad, yassop...he should recognize his own son. Is it because of we only can see his back? but i think most of strawhat enemy know him.." that long nose guy..."
one more, if shanks and whitebeard are going in action now, attack the world government and they're suddently meet luffy and his crew ( just a thought..) ...yassop won't recognize sogeking is his son , rite?
