Finally finished the episode. I'm actually warming up to Vince Vaughn - I think he plays a pretty good 'career criminal trying to go legit' in this show. I still keep waiting for him to say 'earmuffs' or something but overall he's not *that* bad.
As to the ending, it sure looks like Ray bites the dust. If not (and the previews seem to suggest as much with his boss saying one of his guys was 'shot', and not necessarily 'killed'), he's going to be hurting for a good while.
Getting back to the 'who done it?', I've ready some pretty good theories out there. This one is my favorite, and draws on more Lovecraftian influence:
Much like last season was the King in Yellow, our Lovecraftian companion this season is Nylarthotep. Everyone has two faces. There are masks and egyptian symbols everywhere. And that little comment about Paul having "something happening to him in the desert" reeks of Nylarthotep's touch. Even the "convocation of influential men" and the creepy clinic of heightened awareness all speak of the messenger of the Great Old Ones. The fact that Ben Caspere's corpse faces west over the ocean is huge, too.
All that being said, I think there are three possibilities for the killer.
1) Paul Woodrugh: This is an awesome idea except for the fact that he likes to ride motorcycles too much. This guy would never drive a body in a car anywhere if he owned a motorcycle. The same thing that makes him an awesome suspect also eliminates him.
2) Ani's Dad: This is precisely the sort of guy who runs a cult of Nylarthotep. A guy who murders people because of what he knows about them not to expose their shame, but simply to create chaos and watch the chips fall out. When a guy says "We are living in the last age of man" he doesn't mean that he's trying to prevent this.
3) The rapist of Ray Velcoro's Wife: We have here a situation where two guys hit a guy over the head a bunch of times and left him in a ditch. Add this to plastic surgery to repair a face, a bunch of mystical weirdoes in a clinic, and you have a recipe for a serial killer. Now we haven't seen this guy yet, but it's possible that he could be Woodrugh (Conceivable, but unlikely) or the Judge's son. (Not mentioned by name.)
Anyway, things got super serious this week - looking forward to the next episode!
