As much as I love Sanji, incident with Usop in Water 7 and Kuma in TB plus in PH how Zoro reminded Luffy clearly shown Zoro act more as VC. Plus how WCI is wrong. Leaving the crew in Zou was correct decision, but kicking Luffy was wrong. He could have simple talk with Luffy and so on convince Nami to bring Luffy away but he choose Usop approach insulting and fighting Luffy. He has intelligent which may below Robin and Nami. Oda clearly choose Zoro.Even in the end Sanji always awesome.
