Ohhh. Sh"t this has so much sense (I don't know if it's true but look at this parallels) Sanji had a good mother and bad (like really BAD father) Sanji's Mother died trying to protect Sanji and eventually Sanji was forced to leave his homeland because he was wrong (he wasn't as good as his brothers he was the mistake) and he would have been killed by his family (Father) since he was defect one and shame of his Father.
If Zoro is son of Orochi and Toki that is examplening why Zoro lived his homeland (because he was the mistake, he was the shame of Orochi) Zoro's mother tried to protect her child and send him as far from Wano as possible since both Orochi and Oden's falowers would tride to kill him, since he shouldn't have existe in first place just Like Sanji, Zoro's mother was good and his father was bad just like Sanji's, both of them end up in east blue. I never colld Oda a genius because I didn't think he was but if this plot twist is true even I'm going to call him a genius.
