Do you think that the line Sanji said 'A man forgives a woman's lies' to Chopper was because of his experience with Reiju? (Honestly, as much as I love Sanji, I find his character really the most mysterious and complex out of all characters in OP..)
Hmm, I’m not sure if Sanji categorizes Reiju as a ‘woman’. As much as I’m reluctant to say it, they’re siblings after all. More than anything, apart from his conviction as a chef chivalry is the value Sanji cherishes the most, so I doubt he learned something that’s so important to him from any of the Vinsmokes.
We don’t know exactly what Sanji and Reiju’s relationship is like, but one thing’s for certain: Sanji might not hate her as much as he hates Judge and his brothers, but he definitely doesn’t like her. Hell, we don’t even know if Sanji actually forgave her at all. So no, I don’t think he was thinking of her when he said that line. Plus, from what we got from his backstory so far, I think we can say that Reiju ‘lied’ to the other brothers, not Sanji.
Then the question is: who instilled this chivalry code to Sanji, almost to the point of brainwashing? We know it’s not Zeff, so was it his mother, or someone who helped him escape to East Blue? Was it someone he met on the Orbit? We’re so close to finding out the answer and I can’t wait..!
Sanji might not be the ‘most’ mysterious character, but he certainly was hiding a lot of stuff until now. All those little hints Oda gave about him here and there… one reason I was so fascinated with him was because his secret seemed to be the key to one of the biggest secrets of the OP universe - the Red Line. We know nothing about that huge continent ring yet and I’m almost certain that Sanji somehow managed to cross it to reach East Blue. We also don’t know anything about the All Blue yet and it also seems to be relevant to the big picture (destroying the Red Line to unite the four blues maybe..?). Anyway, I’m so glad that I can finally learn about Sanji’s deepest secrets!
