Yeah, I get it, I used to be a Yamato supporter, to me both Tama and Yamato seem to be somewhere between Vivi and Jinbe situation, accepted by the crew, but delayed to actually sail off with them. For Tama, I take it as a W, she's guaranteed to have a spot with the crew. For Yamato, I take it as L, because Oda shat on their dream to leave the island and left them babysitting Momo. But there's no point in getting them to the poll again, SH move only forward, so I don't expect them to get back to Wano anytime soon. If any of them joins the crew on Sunny at the end of the series, it's going to be them travelling to the place where SH crew is, not the other way around.
Waitaminute....seeing Oda's tendencies to extend his cast every arc, will we have every goddam character in the last epic war? That's going to be such a mess
