Suspicions are aroused when visionary spiritual leader John turns up mysteriously at the community's door with his ragged group of disciples. When Abby allows Linda, a pregnant woman from John's group, to stay with them until the baby is born, Anya fears that she will be forced to reveal that she is a doctor. After facing her personal demons, particularly over the death of Jenny Collins, she goes on to successfully deliver a breech birth. She becomes concerned for the group's safety after John becomes increasingly erratic. John proves to be a paranoid schizophrenic. In the research facility, the scientists there discover Abby's video message and find out she contracted the virus but still survived.
