'True Blood' Casting: Meet Eric's...Sister?

Lucy GriffithsIt wouldn't be a new season of "True Blood" without a slew of new supernaturals to keep tabs on. And though filming hasn't started quite yet on season five of HBO's vampire drama, we're already getting our first taste of new blood.

TVLine is reporting that British actress Lucy Griffiths (formerly of BBC's "Robin Hood") is joining the series as Eric's (Alexander Skarsgård) vampire "sister" (i.e. both were created by dearly departed Godric). Lucy will be a series regular, meaning we'll see a lot of her come summer 2012.

The report describes Lucy's character Nora as "intelligent, intimidating, cool under pressure and a very good liar." Traits which will come in handy as she goes all double-agent like within the Vampire Authority.

It'll be interesting to see how this long-time female acquaintance of Eric's meshes with the other women in his life, namely sworn-single Sookie and Eric's own progeny, Pam. Though Nora cares dearly for Eric, she's apparently "dedicated her life to a higher purpose." What do you want to bet that higher purpose involves bedding at least one bloodsucker this season?
