I just finished season 3
SPOILERS
I enjoyed the season but I am not the biggest fan of the ambiguous ending with Gloria and V.M. Varga just staring at each other and him fading out. What am I supposed to make of that? I was kind of rooting for Nikki to off the bad guys, that angel-like character she met in the bowling alley made it sound like she'd vanquish the evil and recite that passage to them. She didn't get to really use that line on anyone (other than mumbling it under her breath before she failed to kill Emmit) and she didn't kill Varga or Emmit. She did wipe out many of Varga's thugs, maybe that is what he was referring to.
