I enjoyed this episode, Red tying up loose ends was great. But the case with The good Samaritan really felt like "Black List does Criminal Minds." It seemed like a case that could very easily pop up on that show, which I suppose makes sense because it was a case Lizzie caught when she was just working as a pro-filer. I did like her threatening the abusive husband at the end of the episode though.
So I'm assuming the end of the episode implied that Red would now be feeding Lizzie information but on his own terms, and not being the FBI's "pet," so to speak?
