'True Blood': Robert Patrick is Alcide's dad

robert-patrick-true-blood-gi.jpgThe ever-expanding universe of "True Blood" will grow by yet another person this season -- and also flash back to a time when werewolf Alcide was just a pup.

The HBO series has signed Robert Patrick to a recurring part as Alcide's ( Joe Manganiello) father, Jackson, True-Blood.net reports. He'll make his first appearance in the season's ninth episode -- which will flash back to the 1980s, when Alcide was a teenager and very much looked up to his old man. Now, though, Jackson is a shell of the man he once was.

Additionally, The Hollywood Reporter says Jackson's own father owed a debt to Eric ( Alexander Skarsgard), and by way of repayment he convinced Alcide to help Sookie ( Anna Paquin) look for Bill ( Stephen Moyer) back in Season 3.

Patrick ("Terminator 2," "The Unit") also stars in ABC's new drama "Last Resort," which is set to premiere in the fall.
