Re: One Piece 667
He has history with Luffy, and Law has one of the most hax DFs in existence. We saw that Monet knew about the Ope Ope no Mi, BB could get his hands on that type of info himself.
But all of this would only matter if Luffy accepts Law's proposal. I don't think he will, and this also pushes CC away from what is going on a bit. Sure he is evil, but I would like him not to be such a cut and dry villain. Hopefully he will be connected to this key Law is looking for.
