re: "the Cal that shows up post-scratch being a fake" **technically** by juju rules/standards pre-scratch Cal is the fake one, even though the post-scratch version is the one that doesn't get the souls. That's totally incidental to your point though, really interesting stuff.
I don’t think this is true and I’m not sure what makes you think this is true? the post-scratch Cal is “HOLLOW. NOT YET FILLED WITH BAD JUJU.” the souls inside are what make it a juju.
