I didn't even say he would get miraculously healed.
I'm just saying there are legitimate reasons to think there will be some kind of payoff from this. It could be lore drop. It could be a further step in the process of mastering or blackening Enma.
Hell it could even lead to Zoro getting ACTUAL medical attention, not just some magical healing.
But this shit is not normal. It feels like you're treating it as a regular occurrence or something quite easily explained while I don't think that's the case.
Even if it ends up being a hallucination, which is likely, we still need an explanation. It would be kinda dogshit if we were left to just assume it was a hallucination and move on as if nothing happened.
Before, you were saying that there does not have to be a payoff from this. I think it would be stupid for there not to be a payoff, considering Oda went out of his way to give Zoro another plotline. Almost everyone else who finished their roles/fights barely have shit going on. Sanji is still KO'd as far as we've seen; he's been given zero panel time since his fight. Chopper, Jinbe, Franky, Nami and Usopp are doing some random end of battle bullshit. Yamato was doing some bullshit with the bombs and now that plotline is over. Brook and Robin are the only ones left with an actual plotline but they've really just been running around for god knows how long and they've barely been given significance.
Zoro is the ONLY one who has a new, strange plotline starting.
