Wouldn't be surprised if Karn's first course of action as the new Master Weaver (come on, it's obvious that's what's coming next), other than hopefully unceremoniously mindwiping Otto and dumping him back in time before he can bullshit an out, is reviving the slain, because it's still a really fucking depressing ending otherwise.

But then there's a Spider-Verse Secret Wars spinoff with Mayday prominently featured, so I guess she doesn't get to go home just yet. I suspect Arachnia on Battleworld will be the chunk of Loomworld with all the Spiders on it who couldn't go home for whatever reason. Or they're actually pulling the 'Spider-verse Mayday is different from MC2 Mayday' card, since we know that's MC2 is on Battleworld from A-Next showing up in teasers.

And it's not by Slott, so it might in fact be passable! Whereas Renew Your Vows/One More Day is his playground so urgghhhhh.
