Sanji had the same resolve as Zoro, the scene wasn't exclusive to him, and in the same arc all the strawhats were given the same chance to sacrfice themselves for luffy before the uransus shock and they all did.Did I say confirmed LOL I said showed.I know Oda didn't confirm it directly but you can see it indirectly
So why were you saying Sanji would be a better vice-captain than Zoro when you think no one is a vice-captain xd You could have just said no one is better rather than arguing how Sanji is more intellectual and things xd
Oda also showed who and what is Zoro at Water 7 arc with Usopp thing...Oda also showed who took Luffy's pain.That all was indirectly showing what position Zoro holds in SH's and who is the most closest and captains right hand.
The water 7 arc incident I never disagreed with but others have done things of that caliber as well
Wait how does that make him more special than others? Zoro also went to help sanji with kiemon just because nami asked him....Funny thing if you remember at Alabasta when Smoker nearly drown I wonder who Luffy asked to save Smoker....Oh snap it was bloody Zoro again out of all SH's it was again Zoro :/
Only once, from a fanboy like barto. The scene showed that zoro is thought of more highly than the other strawhats indeed, perhaps stronger as well but that assumption can easily be made by the government due to the fact that he fights first mate 8 time out 10 if not 9.Not to mention how Oda is consistently connecting first mate/vice-captain title with Zoro in manga.Zoro and only Zoro.Wonder why :/
