Joe Manganiello, Robert Patrick

Get ready to meet the werefather!

Robert Patrick has been cast as Alcide's father on True Blood, TVGuide.com has confirmed.

Patrick will portray Jackson Herveaux, whose debt to Eric (Alexander Skarsgard) was what brought werewolf Alcide (Joe Manganiello) into the fold on Season 3 of the HBO series. According to True-Blood.net, Jackson is introduced through a flashback to when Alcide and Debbie Pelt (Brit Morgan) were teenagers, and Alcide actually looked up to his father. In present day, that's not the case since Jackson has apparently given up on life.
