Lois has been the narrator throughout, so she likely makes it through to almost the end to at least recount all these events in her journal. It'll be interesting to see if they go a Walking Dead like route with some survivors eventually rebuilding out of the ruins or if this was meant to completely close that avenue off. I can see Taylor having Jon and Lois survive as kind of an inverse of Injustice, what the world they survive in looks like is the question.

Taylor needs to get on a proper Super book. He's been killing it now and this event selling like it has has got to have made his star rise at DC enough to warrant it. Injustice was popular but never a best seller like this. This is consistently one of the top books.
