Or maybe she just had tuberculosis...

This is precisely the premise of "snow, glass, apples".

But why would the mirror on the wall call her the fairest if it couldn't even reflect her?

Sounds like some Goth chicks I used to know.

Yeah, yeah, ill get to it when I finish the Cinderella redo I've been working on off and on for years now.

Seriously, this isn't the first time the idea has come up. The description has made people say hmmm since before that phrase was in made popular by Arsenio. My little group of jackass weirdo friends talked about a bunch of those old stories and how the various descriptions and phrasings aren't really executed well.

I've thought about snow white being some kind of supernatural creature as the basis for a story a few times over the years, but it isn't as inspiring as I could hope. The Cinderella redo is more inspiring, but the take I have on it is difficult to get right, so it's slow going.

I may well end up doing the snow white thing as a more direct rewrite, I dunno.

The poisoned apple had just garlic inside.

Sounds like someone has never seen Stoya
