I think if she joins the crew in the end, Luffy will probably encourage her to drop the Oden thing and define herself. Assuming if it does indeed happen. I imagine Luffy will be cringed about it too eventually haha
i know afterwards that after Wano, Oda should give a chapter to the addition of Jinbe and Yamato interacting with the slice of life moments of sailing. Or at least the realities of sailing in the New World interacting as a crew. As Yamato, rather than masquerading as Oden
