@TealBlueShore:
Hm… that would mean that Shanks has seen the One Piece and knows what it is Luffy's after, right? Or did Luffy not tell him he wanted to find the One Piece and only wanted to become a great pirate?
About Buggy and Raftel, and how he's only focused on other treasures, maybe he's not interested because he knows what it is, having been on Gol D. Roger's crew and all. Either that or he knows what it is but is trying to amass a great fortune so that once he's really rich he'll head there and add that wealth to his "flashy" fortune and truly be the richest pirate in the OP world. Who knows. But if the One Piece wasn't a big "flashy" pile of gold, it would sort of make sense that Buggy (Omagosh, I accidentally typed "Buffy" XDDD... yeah, it's late and I'm getting tired) wouldn't go after it, right? Or maybe he just doesn't care.
Sorry if my post doesn't make sense in some parts; as noted above, it's getting late.
In my mind, Buggy and Shanks haven't been on Raftel…
If you look at what Rayleigh said, it was after dismissing the most of the crew then they decide to go with a few guys and Crocus for Raftel !
Is it clear for everyone? I mean I tought it was clearly stated back then !
