Following the shocking revelations in the unofficial leaks for "One Piece" chapter 839, it seems that Sanji will have to push through with the wedding as he is being blackmailed by his father, Jajji Vinsmoke.

As fans know, Sanji wasn't raised by his own family. As a young child, he was rescued and saved by Zeff, who taught him with an iron-kick how to cook and serve people with sumptuous meals. When Sanji said goodbye to his beloved mentor and left for the seas with the Straw Hats back in the days, Zeff supported his decision, knowing that his apprentice will one day do the impossible and reach the legendary "All Blue."

Rumor has it that fans will see a brokenhearted Sanji saying his vows to Charlotte Pudding in an effort to save the life of his master and dear mentor. Though it is unclear if Jajji is telling the truth about tracking down Zeff's whereabouts, Sanji will most likely bend to his father's orders so Zeff's life can be spared.

There are speculations that Luffy and the Straw Hats will finally reach Sanji before the wedding takes place in "One Piece" chapter 840. The big question is: Will Sanji join his comrades knowing that Zeff's life could be in danger?

As for the other shocking revelation, it is expected that whatever dirty business the Vinsmokes are into will be revealed in "One Piece" chapter 840. In the previous chapter leaked before it gets officially launched, Germa 66 soldiers are seen in capsules that appear to be those used for cloning.

Sanji will be very shocked to discover what his family's business is. On the other hand, it's not surprising that the great clan is involved in highly technological innovations such as cloning since the Vinsmokes are known around the "One Piece" world as advanced in weaponry.

Rumors about "One Piece" chapter 840 go as far as predicting that Sanji will discover his siblings' true roots. It is speculated that his other siblings are clones of Jajji, and he may be one too. The big difference is, Sanji might have acquired the good traits of his father while his siblings unfortunately got all the wrong and evil ones. If Sanji is a cloned version of his father and he finds out about this, will this be reason enough for him to leave the Straw Hat crew so he can keep them from potentially being subjects of the Vinsmokes' experiments?
