Izzy is Sam’s eight-year-old sister. The intrepid and independent Izzy talks with a pronounced lisp and refuses to go to speech therapy despite the fact that the other kids in her class make fun of her. Sam pities Izzy, and wishes she could influence her sister toward a decision that would allow her to fit in—but as Sam relives Cupid Day again and again, she decides to spend one day of the loop skipping school and spending time with her baby sister. As Sam and Izzy bond, Sam comes to realize that Izzy’s independent thinking and shirking of social norms is actually an inspiration—Izzy is entirely herself, and does not change anything for anyone. Through her younger sister’s example, Sam learns a little bit more about who she herself is, and begins to focus on how she can honor her inner self and stop relenting to the social pressures at her high school.
