See, here's what I'm not getting. What happens at the end of the story.
Yeah, we're breeding frogs and we're going to start a new universe. There's implications that the humans are supposed to pair up and repopulate, but honestly that seems pretty ridiculous from where I'm sitting. Is it just, raise frogs -> bad guys attack -> repel bad guys -> new universe -> roll credits? That doesn't even explain what's going on with the trolls at all. Surely they need to have a hand in the upcoming events and right now there's no room for that at all.
I really do think we're getting them back at the end of the story, even if it's just something like the end of Problem Sleuth, where there was this Greek heaven place. Heck, even if they don't impact the plot any more, I still don't believe that we won't see them again. Would Hussie just close the curtains over the miniscule number of remaining cast characters at the end and call it a night? Eh, don't answer that.
...Man. Who's going to be in the third universe? We have NO information to guess from there. An entire third race, trolls->humans->something else? An empty world that humans and trolls and even dream-world people will all move in to inhabit, possibly including people who get revived after the story's climax?
Or I guess if you really wanted to get ridiculous, a total failure along with "The future refused to change...", then the most epic flash ever that lets you start over, replay all the scenes that went horribly wrong, and fix them.
