Now that Dexter is done slashing, it’s time to look forward to sundown. “True Blood” has fresh blood. Meet Lafayette’s mom: It’s Alfre Woodard! The Emmy-winning actress has been tapped to guest star on Alan Ball’s vampire drama “True Blood” as the mother of Lafayette Reynolds (Nelsan Ellis), the cook at Merlotte’s who got busted for selling vampire blood and held captive and tortured by Eric (Alexander Skarsgard). Since Lafayette and Tara (Rutina Wesley) are cousins, it means that Sookie’s best friend would be getting a visit from her aunt. The series follows Sookie Stackhouse (Anna Paquin), a barmaid living in Louisiana who can read people’s minds, and how her life is turned upside down when the Vampire Bill, walks into her place of employment two years after vampires ‘came out of the coffin’ on national television.
