How do they hide that they’re Returned? Well, it comes down to mastery of their ability to change their appearance. They can’t shape-shift entirely; they can just alter some things about their appearance. They can change their weight, their hair color, and things like that at will. Vasher doesn’t do this often, but Denth has been known to use it as a disguise. The problem, after you do this once and someone realizes it, your nature becomes very suspect.
