Chapter 956: This is the most important one. In this chapter we learn that the Warlord system is now over and the Marines want to capture the Schichibukai. In the same chapter exactly, Blackbeard says he will not let the Marines have it. I believe we can assume he is speaking of a Warlord and knowing what we know about the past of Buggy, it’s gotta be the clown.
Chapter 966: We see Blackbeard facing Shanks and Buggy. Of course, we know something will happen between Shanks and Teach but Oda chose to include Buggy in the panel. Maybe, Buggy will play a role in Blackbeard and Shanks’ story.
Chapter 967: Shanks promises Buggy they will one day go to Laugh Tale.
But I don’t see any reason Buggy would today go willngly to Laugh Tale when we know that he is not interested by the One Piece. He may well be forced.
Finally, we know something is going on between Shanks and Blackbeard. One day, these two guys will fight as foreshadowed by their Marineford meeting or the fact that Shanks warns everyone of Teach.
Buggy may eventually be the casus belli, the reason why Shanks will fight Blackbeard. For his friend. Because ultimately, all is about friendship in this world. From this point of view, one may even argue Blackbeard would capture Buggy only to attract Shanks in his island but I do not really see it that way.
