Another day, another exciting piece of True Blood casting news.

Within the last 24 hours, Grant Bowler and Marshall Allman were both added to the season three cast, in the roles of a werewolf and Sam's brother, respectively.

Now, Entertainment Weekly reports that Shannon Lucio - who appeared briefly on Prison Break with Allman - has been cast as Bill’s Compton's human wife, Caroline.

Viewers got a glimpse of her during a season one flashback (when she was played by a different actress that was never officially listed as part of the True Blood cast), as Bill never returned to Caroline after he was turned vampire during the Civil War.

Lucio has guest-starred on Grey's Anatomy and Criminal Minds. She also appeared for multiple episode of The OC, as Ryan's step-sister Lindsay Gardner, just as that show started to fall apart.
