Hey guys i have another crazy theory.
First we all know big mom wants to alliance with germa because she wants their army. But look at germa here. What is germa want from big mom? What do you guys think? I think germa or vinsmoke family dont want another army because they already have an army. I think vinsmoke is looking for something important like poneglyph or tamatebako. Because if vinsmoke just want an army why not ichiji or niji to marry with pudding? Or why not his father (with big mom)? . I think vinsmoke already prepared if big mom betray them by sending sanji to marry pudding. Remember vinsmoke can manipulate the wanted poster that mean vinsmoke have connection with marine right?.
