Sci-fi thriller Orphan Black races into another breakneck season on BBC America (Saturday, 9 p.m. ET/PT), but the female clones of the cryptic Project LEDA (all played by Tatiana Maslany) won't be the only ones getting in on the action. As promised by an eleventh-hour reveal in the Season 2 finale, male clones from the militaristic Project Castor (played by Ari Millen) will shake things up for Sarah and her "sisters," deepening the mystery of their origins.
"The story of the male clones is really seen from Sarah's point of view," because the show has "always been (her) trying to figure out what the hell is going on," says co-creator Graeme Manson. "It was really a critical part of moving the ball forward this year."
