There's nothing that would stop Leo from seeing things about Rutile, but there's nothing there to really see, either: Rutile doesn't have any kind of magic ability or glamour, they just use makeup in place of skin.

That said, Rutile is definitely not human, so if Leo can see all the way through to their chemical structure then that's totally cool by me. (Actually, I'd love that.) Otherwise though, Rutile's pretty boring to look at.

The vision hijacking seems awesome, though, and I'd love to play that!

TiO2 structure | under all that powder Rutile is actually just dry spaghetti
