Uncanny Jack
Everyone thinks the uncanny folk steal children, but they steal adults too, steal their minds and memories, put their own folk where ours used to be. The new folk don’t know their loved ones, don’t know what a toilet is, don’t know how to deposit a check. Of course they don’t. Why would they? They didn’t need any of that, didn’t know any of those people, where they came from.
