[The entire explanation sounds like it's way too steeped in spiritualism and stuff Charon doesn't really understand, nor does he particularly care about. He can't tell if these "fiends" are a real physical thing where this man comes from or if it's anything like all those "vengeful pissed off ghost" stories people used to tell.]

This world ain't like mine either, but I think when people die here that's it. Light's out. Don't think them coming back as a monster is a real concern.
