Brian J. Smith, star of Syfy's Stargate Universe, dishes about the cast in the second part of our exclusive video interview, revealing who owns a fart machine and giving us his dead-on impression of co-star Robert Carlyle.

Smith, who plays Lt. Matthew Scott, also offers up insights into the future of Scott's relationship with Chloe (Elyse Levesque) as the first season resumes on April 2 at 9 p.m. ET/PT.

"With Chloe and Scott, I never really thought it was about sex," Smith says, adding: "That relationship is based on two people who look into each other's eyes ... and understand a kind of pain that very few people understand."

Stargate Universe airs Fridays at 9; it has been picked up for a second season, which kicks off in the fall.
