Cinder recognizes that she will now face discrimination both from Earthens (because she’s a cyborg and a Lunar) and from Lunars (because she’s a shell). This speaks to the universality of stereotypes and discrimination—it seems that every society has at least one marginalized group. Even now, knowing that she herself a Lunar, Cinder clings to negative stereotypes that paint all Lunar people as cruel. Dr. Erland’s warning also hints at the lengths to which Queen Levana will go to control and manipulate those around her, rooting out anyone whom she cannot brainwash.
