Favorite Son

Entering a new sector, Harry Kim feels a powerful sense of déjà vu, develops a rash and acts on strange instincts when a Nasari ship appears. His instincts lead Voyager to Taresia, a world of mostly female inhabitants, who tell him he was sent to Earth as an embryo, carried by a human mother, and that his Taresian genes are only now awakening. Welcomed as a returning son, Kim is tempted to stay, and he befriends Taymon, another man who has come home. Meanwhile the Doctor discovers that Kim is human after all: a virus has rewritten his DNA. When Kim finds Taymon's withered body, he learns the truth: the Taresians lure men in and drain their genetic material to reproduce, killing them. The planet is sealed by a polaron barrier, but Voyager breaks through and rescues him while fending off the Nasari. The Doctor removes the alien DNA, and Kim compares his escape to Odysseus and the Sirens.
