From the impression I'm gathering is that they are "inherited Wills" passed on from person to person. The overall "Will of D" seems to be a form of destiny that varies per individual exactly. With Blackbeard, its a simple case of he has the "D" but the wrong "will" whereas Luffy looks like he will inherit both Roger and Ace's now. The real question is, if BB isn't carrying Roger's will, whose will IS he carrying?
