When Skye and her mother are at the mountain, the position of Skye's hair and the intensity of the wind changes between shots.
Skye mentioned time that she had spent in an orphanage. North American orphanages were phased out after World War II in favor of the foster care system. The last government run orphanages in America was closed in the early 1970s. While names of private / religious run entities have also dropped the name orphanage, the were still sometimes referred to as such by those living there long after the official name change.
