Crisis on Infinite Earths – Speculation Thread

We are just one week away, folks, from the conclusion of the Arrowverse’s crossover event Crisis on Infinite Earths.

Last we left our heroes, the entire multiverse had been wiped out from existence, and the only people left alive were Kara, J’onn, Kate, Barry, Sara, Ryan Choi, and Superman Lex Luthor, stranded at the Vanishing Point. That’s one hell of a forking cliffhanger. So I decided to create a space where we could all share our speculation and wild theories about how this is all going to shake out in the final two hours of Crisis. No theory is too wild and half-baked here, folks!

So tell us: Will worlds live? Will worlds die? And will the Arrowverse ever be the same?
