Reiju has been wounded and it appears that she doesn't know what happened to her or who attacked her. Recent "One Piece" chapter 850 spoilers suggest that the Vinsmoke daughter's wounds have been caused by someone with Devil Fruit abilities.
As seen in chapter 849, Reiju wasn't around during the Vinsmoke meeting. The catch is, Pudding also didn't meet with Sanji for lunch. Some "One Piece" chapter 850 spoilers indicate that Pudding may have had something to do with Reiju's wounds. It is speculated that Pudding has hidden Devil Fruit abilities and she could have been the person who attacked someone as skilled as Reiju.
Other "One Piece" chapter 850 spoilers predict that more of Reiju's cliffhanger will be discussed in the upcoming installment. There are reports supporting the speculation that Pudding was the one who attacked Reiju. Pudding's abilities have not been highlighted in any of the previous chapters yet and her powers may finally be unveiled soon.
On the other hand, there are also some fans who believe that Pudding will never do such a thing. Reiju appears to be the only Vinsmoke sibling who cares for her brother. If the recent "One Piece" chapter 850 spoilers are true, fans may be in for a huge surprise. This will also hit Sanji hard. The previous chapter implied that he may be starting to develop romantic feelings for Pudding as he was last seen preparing a meal for his bride-to-be.
Meanwhile, there are also reports that hint on a potential emotional arc coming up in "One Piece" chapter 850. It is said that Pudding may decide to end her life so she can stop the wedding. This could be the only way to allow Sanji to live free with the Straw Hat pirates, whom he considers as his family.
Chapter 848 saw Pudding paying a visit to Sanji's friends who are imprisoned under Big Mom's orders. Before she left, she said something that has yet to be disclosed to fans. She also said goodbye to Luffy and Nami with tears in her eyes. It is then speculated that "One Piece" chapter 850 may see Pudding pull off the ultimate sacrifice that will keep Sanji from being miserable forever.
"One Piece" chapter 850 is slated for release sometime next week. Stay tuned for more spoilers and updates!
