You'd think by now we'd have heard most of the major castings for 'True Blood's fifth season, which debuts in just 10 days on Sunday June 10.  Still, every so often HBO will play their guest roles close to the chest, and it seems that we can add one more name to the roster of 'True Blood's fang-banging fifth year.  So, who's the lucky lady?

TVLine has announced that former 'Napoleon Dynamite,' 'Veronica Mars,' and current 'Bones' star Tina Majorino has landed a role in 'True Blood's forthcoming fifth season, to debut in the third episode airing June 24.  Majorino will play a "key member of the Vampire Authority’s support staff," though it remains to be seen if her character will be human, or a vampire like her bosses.  Personally, we like the idea of Tina Majorino in fangs.

Majorino joins a number of other prominent castings of the Vampire Authority out to find Eric Northman and Bill Compton, including 'Law & Order: SVU' star Christopher Meloni, 'Spartacus' star Peter Mensah, and 'Hell on Wheels' star Christopher Heyerdahl.  We're left wondering why Majorino's casting wasn't announced earlier, which could lend some mystery to her recurring role.

What say you?  With only days to go, are you chomping at the bit for fresh 'True Blood?'  Tell us what you're most excited to see in the comments!
