A student with extremely conservative political beliefs brings up charges against Andrea for the liberal bias she believes Andrea has against her in class, and Chadwick's mother/daughter weekend heightens Nell's feelings of loss regarding her late mother. Historical figure Daniel Ellsberg makes a cameo appearance as himself, a guest lecturer discussing his role regarding the Pentagon Papers and the Vietnam War. After Andrea kicks the conservative student, Ana, out of Ellsberg's lecture for heckling him, Ana decides to lodge the official complaint against Andrea -- stating that Andrea's liberal views have affected the way she treats her and grades her. Although she is at first aghast at the charges, Andrea soon begins to wonder if her disgust for Ana's views has, in fact, influenced how she grades Ana's work. Meanwhile, feeling the need to remember and connect with her mother, Nell is especially troubled to learn that Max has started a relationship with Lyla. (thetvdb.com)
