Wow, wasn't expecting us to dive that deep into Sanji's history this chapter. It's all been pretty much confirmed now that most of his family isn't redeemable. I was holding out some kind of hope that maybe Jajji had some other kind of plan for Sanji, but seeing how he felt this way about him from the beginning, its very unlikely. What I am still holding onto though, is Reiju having some good qualities, and caring for her little brother. She could have just been lying about why she was laughing, but Oda seemed to hint that she was fully aware that he wasn't dead. And now going back to her intro, it makes more sense to me how she thanked the Straw Hats and Luffy for taking care of him.

I'd hate to start a power hierarchy discussion, but it makes no sense to me to discount Sanji from being able to kick his family's ass. He's being blackmailed into not fighting back, and we know he already kicked Yonji's ass. I refuse to believe whatever stealth technology any of them have is above Sanji's Kenbunshoku, or whatever martial arts they've learned is significantly better than the Black Leg Style. Granted a big part of this is extreme bias from my exasperation with Sanji getting jobbed, but you gotta admit he's due for something big, and that seems to make the most sense. On another note, I'm still not getting how the Vinsmoke children came to be. Jajji mentioned a mother, but its been hinted that they are bio-engineered to some degree. We've also definitely seen Sanji's strength.
