Alejandro continues to be attached as a regular to Southland, which recently moved from NBC to TNT. Because of the cable network's plan to air the 13 produced episodes of the cop drama, starting Jan. 12, before making a decision whether to order a second season, Alejandro can accommodate "Blood" while keeping his obligation to "Southland."

On True Blood, he joins such other new additions as Denis O'Hare, Marshall Allman, Theo Alexander, Grant Bowler, Joe Manganiello and Lindsay Pulsipher.
