Did you forget he's fighting Lucci??
Boss Jimbe is still on Labo phase since he is one of people that responsible to bring Vegapunk Stuff ( Sanji leave to save Bonney ), there are 2 scenario on my head that seems logical to be a plot next chapter because Oda keeping Jinbe on Labo phase
1 scenario -> Zoro defeat Lucci, Lucci then recovers again just like his fight with Luffy ( or like when Ulti fight Yamato and instantly recover altho not fully ) , then Jinbe the one who stop him ( like Ussop and Nami stop Ulti and Page One to had a fight with Luffy )
2 scenario -> Zoro didn't defeat Lucci, Jinbe then joining the fight and told Zoro to Stop Kizaru since Zoro is much needed to fight him rather than stay on Lucci ( just like when Marco ask Zoro to go against Kaido )
