I agree with everything else, but I will put a heavy and hard NOOO on that happening. The problem with Nami is that Oda blew his load early with her at Cocoyasi with Arlong. Her arc more or less ended there and has never really been spun up again.Nami’s likely set to get heavy focus.
Everyone else still has something to do or challenge, even Zoro and Sanji still have much larger goals after their island episodes. Nami has just sat in the corner doing navigator and thief stuff ever since Arlong and nothing has really changed on that front.
Look, we all like Oda but the man is not perfect. With how many characters and plot threads he has set up it wouldn't surprise me that now we are in endgame he just kind of "forgets" a few of them exist. The major and some minor ones I believe will be wrapped up, but there will absolutely be some threads he just wholesale forgets about that get lost in the sauce of the ending.Also, plot threads not happening the way people want does not mean they are dropped.
