Susan is the first born daughter of Snow White and Prince Charming. Because of the Evil Queen's curse, Susan lost her memories of her real parents and her little sister Emma. Susan is Regina's adopted daughter and Henry's adopted sister in Storybrooke, a town where all the fairy tale characters are trapped. Henry drags Susan to help him find his birth mother, Emma Swan, Susan's younger (or older depending on how you look at it) sister. Can Susan help the family she can't remember, or will she need help along the way?
