The True Blood Season 6 cast is set to expand yet again.

With Rutger Hauer already on board as a villain named Macklyn, and Rob Kazinsky set to play a faerie who woos Sookie, new showrunner Mark Hudis has sent out a casting call for Nicole Jannsen.

The character will be a regular on the upcoming 10-episode season and is described as a "do-gooder to the core." She's idealistic, optimistic and is a vital member of a liberal advocacy group that fights for civil rights.

According to Zap2It, Jannsen is "not at all concerned with money; she's concerned with the common good and doing what's right... Life hasn't beaten her down yet."

Why do we have a feeling that might change once she visits Bon Temps?

True Blood Season 6 kicks off in June 2013. Any casting suggestions for the role of Nicole? Sound off now!
