While the show may have come in a bit under the radar by debuting, and making its foothold in NBC's Friday night lineup, 'Grimm' has achieved a considerable amount of buzz.  Definitively renewed for a second season, this fairy-tale success story has already begun plotting out its second season, keeping its Friday time-slot this fall.  Guess who's got some fangs to bare next year?

Zap2It reports that former 'True Blood' and 'The Cape' (yes, we watched 'The Cape') star James Frain has been tapped to join the second season of NBC's 'Grimm' for an important recurring role.  How important, you ask?  Why, he'll only be playing the brother of Captain Sean Renard (Sasha Roiz), ranking officer of the precinct and member of one of the Seven Royal Houses!

Frain will take the recurring role of the Captain's brother Eric Renard, who maintains a terse relationship with his sibling and comes to Portland following a very bad creature that makes its way into town.  Of course, Eric has his plans of his own and might be secretly targeting Nick (David Giuntoli).  OR IS HE?

'Grimm' will return to Friday nights on NBC this fall, once again competing against 'Fringe' in its final season.  Fellow competitor 'Supernatural' will be moved to Wednesday nights alongside The CW's new drama 'Arrow.'

What say you?  Are you a fan of the procedural spook-fest?  What would you like to see from 'Grimm' season 2?
