The overall theme of the third episode of Atypical, "Julia Says," is change. An often discussed "core symptom" of autism is what diagnosticians call "inflexibility." Ironically, the most inflexible person in this episode is Elsa. She has built her entire identity around Sam being dependent on her. As her family grows and changes around her, Elsa acts out. By the end of the episode she has assaulted a store clerk and is sleeping with Nick the bartender. Somehow, this is autism's fault or something. I still can't tell if she's supposed to be relatable or likeable.
