The week-long national syndication window opens for the 12th episode of Star Trek: The Next Generation. This episode introduces Data’s “brother” Lore, also played by Brent Spiner, and establishes an origin story for both. 
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.
