How does Linda adjust to reentering civilization? Why does John protest his mother’s doctor’s decision to allow her take all the soma she wants? Why does he give in and agree to let his mother stay on a permanent soma-vacation? Do you think Linda has a right to choose to abuse soma?
Linda doesn't do well upon her return to civilization. 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. John worries about her but receives assurance that she feels happier with soma even though she will not live much longer if she keeps taking so much. For the first time, John encounters the civilized society's attitude towards death.
