The story begins as an MRI technician assures Baily that "Contrary to popular opinion, . . . this is not a torture device." The test was ordered because her arm suddenly went numb and she suddenly lost most of her vision during algebra class. With no idea what's wrong, Baily speculates about the possibility of a brain tumor, about how disease will change her life, about early death. She is uncomfortable with her mother's cheery reassurances, which consist mostly of simple theories like the possibility that Baily was reacting to missing lunch, but wants them, nonetheless.

Since the pediatric wing is full, she is put in a room with an old woman for observation overnight. The nurse runs her through a series of highly irrelevant questions about her physical health from drug use to dentures. Then her mother is required to leave for the night. In the morning they take her for an EKG before her mother can get there; Baily returns to her room in a state of morbid conviction that she's dying, which is finally overturned when the doctor comes in to explain to her that she had a classic case of severe migraine.
