I was thinking about this last night and it was mainly about what could be the ability or powers that Juha Bach has that makes him the strongest quincy. Now we know that he imbues his soul into another and gives them abilities and then his soul returns to him in return. But then it got me really thinking, does he still own Yamamotos bankai? It was stated long ago that when a shinigami is born the zanpakuto or adachi are born at the same time and when the shinigami passes on so does the zanpakuto. So this had me wondering even though Juha Bach did steal Yamamoto's bankai does it mean that he still has that weapon in his arsenal? If so, does that mean that when the seal "steals" the bankai that it also takes it life counterpart (ie shinigami) away as well? The best reason to beleive this would be when Toshiro is scared because he can't "sense" his bankai anymore. What do you think? Is it possible for two beings who were meant to live and die at the same time possibly exist without the other? If these two can live without each other does this mean that the other half can bring back the other?
