So how does everyone think this ends?
Do people expect some sort of twist or big reveal?
More drama than a twist.
I agree. i don't see a twist at all. There will be drama, the last 4 episodes have been pretty dramatic, and they are tying up the story. I agree no crazy twist or huge reveal though. Never believed the FIL theory and definitely do not believe Maggie is involved. Reading this thread and hearing people talking about it, i think there are some who do think some big "aha" moment is coming.
I'll probably be very wrong, but I just can't but help to speculate on what will happen at this point. I think Cohle and Hart will die. The show has been pretty deliberate. It sure seemed like Cohle and Marty were coming to terms with their fate in the last episode. I think they go down as heroes, taking down some of the cult. I think there is no "Yellow King" reveal. I don't think the yellow king is an actual person per se, but something mythical that represents the killer cult as a whole. I think Marty and Cohle put a dent into it, but I think it is confirmed to be much deeper than that. keeping up with the "time is a flat circle" theme, the show ends with Papania and Gilbough taking on the role of Marty and Cohle just getting the tip of the iceberg of what is going on. And on goes the battle, with the yellow king living on and Papania and Gilbough begin their voyage to Carcosa.
