I'm pretty much neutral on this topic of CoC, and personally think Sanji could do without it if I'm being honest, coz irregardless of whether Sanji gets CoC or not, it's not really going to change the dynamics of the M3, neither will it affect Sanji's ceiling. Oda will simply just develop Sanji in a different way to keep the balance between the M3 (i.e. again perfect example of this CoC scenario is Law in relation to Luffy and Kidd). That said, like I already pointed out in the spoiler thread, Oda going out of his way to highlight this issue, I think, is evidence of the fact that he's aware of the discussions the fanbase are having with regards to this M3 CoC issue and the optics of just 2 of 3 of the M3 having CoC for better of for worse. If his intention was to leave Sanji behind, first and foremost the whole wings dynamic won't have even been a ting on Wano and there would have been no need to even highlight this issue this chapter.
Anybody that thinks Oda is just trolling Sanji for the sake of it is not really paying attention but I'm not surprised tbh. Mofos first and foremostm, are more concerned with trying to validate their headcanons rather than reading the story
With regards to the question of whether Sanji gets CoC this arc though, I'd say his chances are looking pretty good.
- For one Gaban who is his parallel in the Roger Pirates has it
- Gaban's phrasing this chapter could've easily been "seems like one other person has it" rather it was "seems like more than one has it" and the panel singled out both Sanji and Zoro
- Oda highlighting this CoC issue with Sanji this arc
- Oda to our surprise only just confirming Zoro's CoC this arc and the latter only realising he has it here. Boggles the mind why Oda went this route of Zoro not realizing he had CoC till now but one reason could be that he wants to align it with when Sanji gets it.
Anways from a story-telling perspective route Oda is going with Sanji is very interesting as you never really know what Oda's going to do with him. Oda also seems to express far more freedom with him than the other 2 with regards to what he can do with the character
