Stardate 41242.2: Data visits his home planet and discovers that his creator also constructed – and, for some unknown reason, disassembled – a “twin brother” of the android: Lore. The crew welcomes Lore with open arms, but they soon discover that the greed Data lacks as a human emotion is indeed possessed by Lore.
