Burgess is a dumbass no doubt, but BB definitely isn't. He's one of the foremost schemers of the series I believe, putting on a facade so elaborate no one really knows what he's thinking. He stayed with the WB crew for so many years and no one ever really managed to get a proper read on him I think. No one ever realised his ambitions and I doubt he was ever a sincere member from the start.

But I definitely agree that he wouldn't use any of the fruits Doffy has. BB seems like a more direct person.
