With "Vegapunk's" new design being similar to Sora, Sanji's mother, I think it's very likely that Vegapunk has some kind of connection with her. Either familial (Father, Brother, Mother, Sister, etc...), professional or even just an old crush/friendship.
So more Sanji lore is very likely coming this arc. Hopefully DJ/IJ's origin is explained or at least hinted at. Though mentioning hints, that Lust/desire bit that Vegapunk mentioned couldn't be controled could be the very hint itself for Sanji's emotion powered skills.
I enjoyed seeing Sanji’s family in WCI. Even though most of them turned out to be shitty (with a portion of those not because of their own fault after all), so Im not interested at all in seeing Sanji have EVEN MORE family lore.
I’d prefer if he learned more about his body/genes/fire/what have you instead. That’s much more interesting to me personally.
How is Vegapunk not even a bit similar to sanji's mother, Sora? She looks like a gener bent Sanji without the swirly eybrows ffs. Having practically every female character being a clone of Nami in One Piece doesn't change that.
If Girlpunk was meant to look like Sora I’d imagine the chapter would actually end on Sanji’s reaction to her. Or some sort of acknowledgement that she looks like Sanji, since Sora is pretty much just girl Sanji
Instead it’s Franky who gets the final focus and Sanji’s treated no different from any of the other Strawhats.
