Kaylee doesn't just play Josie on screen — she lives her character through her own imagination when the cameras aren't rolling as well. ". . . every single episode I write a letter to whatever character is interacting with Josie the most," she explained to Entertainment Tonight. ". . . I have letters to Hope, I have letters to my dad, I have letters to Lizzie, the list goes on. And I have a playlist as well. It kind of helps me get into her mind space."
