When Big Love returns in early 2010, it will do so with one of its most disturbing storylines yet:

Viewers will learn that the parents of Wanda and J.J. were brother and sister.  We'll give you a moment to let that sink in...

Also, prepare to meet Roman’s tiny nephew, Toby, and his six wives; as well as Bill’s almost-fourth wife Ana and her Serbian fiancé Ivan.
