When Carl and Elsa leave the trailer after she is attacked and are driving in the city, they pass by the same "See's Candy Store" twice in quick succession.
When Mrs. Fergusen comes over, she asks for half a glass of apple juice, but when Elsa pours the two glasses, she fills them both to the top. However, a hostess often ignores a request for less than a normal serving and will leave it up to her guest to consume as much as they want. In fact, Mrs. Fergusen drank only half the glassful.
