Spiner will be playing Brother Adrian, leader of a top-secret sect known as the Brotherhood Of The Knights Of The Black Diamond (we’d like to see their business cards). Spiner will appear in at least six episodes. Wonder if he’ll be in any featuring Pete Latimer’s mum, who’s played by Kate Mulgrew?
“Artie Nielsen [Saul Rubinek] and the gang are on a mission to pull their lives back together and Brother Adrian is a major obstacle to that,” says executive producer Jack Kenny. "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.”
Season four of Warehouse 13 kicks off in the States on Syfy on 23 July.
