Dr. Veena Rai is a Visitor sleeper agent that experimented on pregnant women and their unborn children as part of the Visitor Breeding Program. Both Erica Evans and Eli Cohn's wife were treated by her. She disappeared, and Erica failed to track her down. After her death, Erica and Hobbes find her safe and uncover secrets of the Breeding Program. Erica and the Fifth Column discover that there are 29 subjects (including Tyler Evans) that have managed to survive into adulthood, in each of the cities visited by a Mothership. ("Birth Pangs")
