About BB`s ability to take 2 DFs.
A thing i thought was weird while seeing it for the first time was,
why did he have to cover himself while taking the secon fruit..?
I mean when he`s the only man able to do so (and that only one time), why is there any need to hide it.
Also i think a big part of being able to have 2 DFs is the yami-yami-fruit itself.
In my eyes he creates a black hole in which he sucks the DF-ability and then he transfers it somehow in his unique body.
The quote Al!ina mentioned from the databook, has still to do with BB being twice as long a pirate and twice so experienced in my eyes.
BB lie quiet all the time, so Ace most likely only noticed that BB was some kind of unique, but i doubt that BB was talking with him :" ya know, i have two hearts\can live 200 yeras etc"..
By that i get an idea.
Maybe, yeah just maybe is BB the son of Saul and a normal human.
You know that would bring back this forgotten chara who had a D. in his name without any purpose so far.
Well, maybe it was any giant, but that could explain why he could longer live(giants 3x so long as a normal human) than any other "normal" human.(and he has such a size(like many OP-charas) which would indicate that he`s a giants bastard)
