List of "normal" humans and those who may have yet to be proven otherwise. In "The Good Shepherd", it was revealed by Monroe that "Kehrseite" is the Wesen word for a "normal" human (KERR-zy-tuh; Germ. "reverse side"). A Kehrseite who knows the truth about Wesen is known as a "Kehrseite-Schlich-Kennen." (SHLISH-kih-nihn; Germ. schlich "sneaked" + kennen "to know, be aware of")
According to Monroe, the only reason why Kehrseiten are capable of accepting the inexplicable is because they can visualize or conceptualize it from their own perspective, not because of them actually seeing it for themselves.
