Seven of Nine begins to exhibit multiple personalities from a wide range of disparate species. The culprit? An ailing Borg "Vinculum" broadcasting a neural interlink frequency from the center of a debris field from an exploded Borg cube. As the crew try to dismantle it, Seven's neutral pattern dissipates, allowing other personalities to take over. Tuvok steps in just as an unfamiliar alien culture challenges Voyager for the Vinculum.
