Robin and Sanji are the only ones I’d say really grew. Robin got the opportunity to payback the crew for relying on her in EL and this time be the one who was standing up for them.
Sanji was also part of that- he accepted that he needed to put Robin in dange— but he also had the growth about the RS. I don’t much like the plotline itself, but it was growth.
I’m not sure I’d say Zoro grew much. I don’t think we saw anything from Zoro that was a new facet of his character. He’s always been extraordinarily strong willed, he’s always had a soft spot for the helpless, he’s always been willing to put his life on the line. Wano I’d say has more been a post-skip solidification of what makes Zoro a man than him needing to grow. I think the Enma issue was just a temporary blip more than anything else.
Nami not giving up on Luffy and saying he’ll be PK, eh, again, I think she’s always been like that, it’s just she showed in hard circumstances. Maybe it does count as growth, I liked the scene, but I’d maybe have to reread.
