I don't think I am hard to detect...also my moon is sextile my Asc.people with a scorpio moon are just generally very intense. sometimes it's very hard to detetct, other times, not so much.
yeah I know a few people with scorpio ascendants and They can be kind and gentle and then suddenly you'll say something they don't like and their stare can cut you in two. no blinking. just like they're looking into your soul hahaha
yeah, it can really intimidate some people, but in girls I like it. You can tell they're not ditzy and they mean business. I'd rather the intensity than be around someone... well, more mundane.
I think fiery eyes would be mostly related to Aries in my opinion.i'm a leo moon and i don''t think i have fiery eyes. though red eyes would be awesome.
