Greg returns from Vietnam, only to reveal that he is being sent back for another year of service. When Joan finds out that Greg volunteered to go back, she kicks him out, ending their marriage. Peggy discovers that Don's African-American secretary Dawn is sleeping in the office, too afraid to return home because of racial violence near Harlem. Dawn is invited to spend the night at Peggy's apartment, but she decides to leave when Peggy appears to hesitate leaving her purse next to Dawn. Sally becomes frightened after reading stories on the Richard Speck murders, leading her step-grandmother to educate her on the concepts of fear and defense. Megan and a feverish Don run into his former lover, Andrea; Megan is upset over constantly running into Don's old flames. Don returns home and collapses on his bed in a weakened state. Andrea arrives and seduces Don, proclaiming that he will continue meeting her because he cannot change who he is, causing Don to fly into a rage and choke her to death. Don awakens the next morning, having experienced a fever dream; he says nothing of his vision to Megan and reassures she does not need to worry about him.
