- Kat is neither blind for Etheric beings/phenomenons, nor does she see all of them in boring simplified versions. All she does is see through Etheric "smoke and mirrors". - If(!) Coyote's Great Secret is true, then you can't change anything the moment you make some people believe in it. Humans have to die for their stories and beliefs to influence the Ether.
I think we keep collectively forgetting this isn't the kind of comic where ancient undead elves give powerful magic boons to the hero, it's a comic where a girl loses her hair clip and a zombie spends 50+ chapters trying to get it back to her.
