Alice Greczyn portrays Madeline (“Mads” for short), a cool, intelligent high school student and one of Sutton’s best friends. She recently faced the departure of her beloved brother, Thayer, who moved to Los Angeles to live with their mom – leaving Mads with a disinterested father who may or may not be abusive towards her. Mads doesn’t know that Sutton’s been replaced by her twin, Emma, but she senses something is up.
