We don't know what happened to him post-Yhwach bath anyway. He could've gotten killed, he could've gotten his wishes and Soul Society went "eh, if it holds reality together and keeps him placated who cares anymore", or he was even rounded back up while comatose and bound in the dungeon again.
And the more I think about it I kinda like how this seems to be setting up everything to be peachy keen only to wreck everything at the last second. Next week will make or break what reputation it has left I suppose, these kinds of endings are always fascinating to me.
exactly, that's the point. We don't know. I said Or, as in another possible solution since the poster seemed deadset on him still being a live.
