Her sheltered life leads to her not being as well-adapted to the apocalypse as other children her age. In "All That Remains", Carlos says, "If she ever knew how bad the world is... what it's really like out there... she would cease to function", which ironically enough, resulted her death later on. However, it is also implied throughout the season that Sarah is stronger and less ignorant than her dad gives her credit for. This is supported by Sarah's determination to learn how to use a weapon (Determinant), her knowledge of wind turbines and its uses, and standing up to Carver when he strikes Clementine across the face (Determinant). It is mainly assumed that she has some kind of anxiety disorder. This mental disorder is further evidenced during "Amid The Ruins" when she, if Clementine saved her at the house, will remark that she is waiting for her dad to return; this implies she is either unaware of the fact that he died, or that she was actively in denial over his death.
