Oh, they know. I've rubbed elbows with Dark King Silvers Rayleigh, his first mate. But for some reason those that are still alive don't seem to care much. Who knows? Maybe they're all as cracked as Roger and think watching the rookies go after it is more fun.

[if it were Luffy, yeah, maybe this adventure wouldn't make up for not searching for the One Piece, but Law? He's been slowly biding his time for years, this is just another case.]
