Yup i knew that, because i genuinely believe it since his parallel which is Sanji had a natural Talent of CoO. Sanji able to hear someone crying from far away is a hint of his great CoO, even Luffy didn't feel it, and i'm sorry jinbe fan we ain't talking about him. Future Sight or anything above is guaranteed.
What i kinda not agreeing or thinking it doesn't make sense at all is how Gyaban able to detect CoC Haki without confronting them, or atleast Sanji. If Sanji had CoC haki Oozing outta him even tho its much smaller than Zoro, we can accept it. But in this one, Gyaban just straight up said He had the Quality of Kings, and able to master CoC, without feeling it or maybe the spoilers didn't explained it even further( classic Spoilers provider behaviour lol ).
But to counter that, we had a case of Blackbeard at Jaya island who didn't believe at Luffy's Bounty cuz he know he is strong based on his haki, he again recalled it again on Impel Down.
So to me we just didn't had an good argument on it except that, and thats okay tbh.
Ain't gonna debate it much further cuz it’s gonna get explanation soon lol.
