Meanwhile, the health of Carter's grandmother, Millicent (Gamma), continued to decline, and his mother, Eleanor, had difficulty accepting her divorce from Carter's father, Jack. Worse, Abby and Carter continued to disagree over whether or not Abby (a recovering alcoholic) should be drinking at all, even moderately. These personal issues come to a head when Abby's bipolar brother Eric reappeared the day Gamma died. Abby giving precedence to her duty as a sister marked the beginning of the end of Carter and Abby's relationship.
