So yeah, we're pretty sure Cohle isn't going to turn Geraci loose. We also know that Cohle has a contentious history with Geraci and that last week's episode ended with Cohle sticking a gun in his face and Geraci threatening to have his ass split in Angola. Did Cohle really just duct tape him up and leave him in a ditch to die? We know Cohle despised him and that they had a history together from Cohle's undercover days, but that's pretty cruel even for Cohle. One loose - or at least frayed - end that we probably won't see tied up in the finale is what exactly happened to Ginger after Cohle and Hart found Ledoux's cook house. What happens if Cohle and Hart's rogue, off-the-books detective work clashes with the formalized, naive, and possibly corrupt investigation of Gilbough and Papinia? Maybe in Sunday's finale we'll learn that he won the Powerball in Alaska and that the newfound financial security is what really motivated him to return to Louisiana and resume his investigation. We're not in uptown Manhattan or anything, but it's still curious.
He's also flying solo on a vigilante serial murder investigation that involves renting an enormous storage locker, traversing the Louisiana coastline, cat burgling mansions, and God knows what else. (Those one or two probably aren't very generous tippers, either.) Rust doesn't lead a very lavish life, but he's boozing constantly and has to smoke at least a pack of Camel Lights a day. We've only seen it during the daytime, but it's hard to imagine there's ever more than one or two conscious patrons in there at any point. Rust works four nights a week at a bar that seems to be perpetually empty. How is Rust supporting himself working part-time in that dingy bar? Oh, and one of Maggie's first lines in the show featured her lamenting, "You don't pick your parents." Also, when The Daily Beast asked Michelle Monaghan if Maggie's family was going to be involved in the show, she said,"Yes, our family - everybody - is still going to be part of the plot going forward." Not only that, but Robert Chambers's The King In Yellow mentions a house by a lake, and Herbert's home is located right next to one. Was Maggie's father involved? Perhaps Audrey saw the video that Cohle and Hart watched in the most recent episode. Everything's sex." That could just be the standard old-man rant, but Audrey was clearly hyper-sexualized at a very young age.
He also nails what Audrey's future holds by telling Hart, "I've seen kids today, all in black wearing makeup. In other words, he's exactly the type - rich, angry, and powerful - who would be part of the Five Horsemen cult, or involved in covering up said cult. When he was first introduced, two things were made clear: Maggie comes from a wealthy family and Herbert is a cranky old man who thinks the world is getting worse. One answer for who exposed Audrey to the rapes is Hart's father-in-law - named Jake Herbert according to IMDb - who looked pretty creepy throughout his time on camera in the second episode of the season.
