About that ask about twin universes, I've been thinking about frogs and... Don't they lay a bunch of eggs? Not all hatch, but I'm pretty sure frogs lay a lot of them. I've always equated this to one universe spawning a bunch of sessions at once.

Yeah it is kind of referenced that usually Multiple Sessions happen as an attempt to ensure at least one is successful, much like how many organisms lay a lot of eggs. I’m looking at you, Sunfishes.
