Linda is the mother of the Savage and the woman whom the Director brought to the reservation. She is an alcoholic and rather obese. After her return to society, she consumes too much soma and dies soon thereafter. Society finds Linda repulsive because of her age, her bad teeth, and her weight. She takes soma in excess, both to enjoy the feeling of "eternity" that she used to feel as a member of civilized society, and so that she can remove herself from the judgment and looks of repugnance of the other members of society.  We can speculate that she might ave wanted to kill herself as well. You can check out chapter 11 fo this.
