Brent Spiner is beaming over to Warehouse 13 for at least six Season 4 episodes.
The actor, forever known to Star Trek: The Next Generation fans as Lt. Commander Data, will debut on the July 23 premiere as Brother Adrian, the leader of a top-secret sect known as the Brotherhood of the Knights of the Black Diamond.
"Artie Nielsen and the gang are on a mission to pull their lives back together and Brother Adrian is a major obstacle to that. The Brotherhood is descended from the Knights Templar and connected to the Vatican. It is charged with the protection of many powerful artifacts, one of which Artie desperately needs to make everything right again."
