Thanks for saying this. God knows I thought Cade Slingblade Langmore was an awful, hateful person, and I am glad he's gone, but he's her father. It's all she knows. The need for parental love and approval is one of those really basic needs. And considering Ruth's life - where she's lived, how poorly her family is regarded in the community, her education and options, being the only female in the family trying to hold it all together - yeah, I can see where her emotions and actions regarding her father are kind of all over the map. Her brain is smart enough to know Cade was a bad man and not good to/for her, but her heart and her dna may be at odds with that.
Ruth is treated like the town's stray dog. Everyone likes to toss her a bone or a scrap and do the minimum for her to make them feel better about themselves, but at the end of the day, it didn't seem to me like anyone really cared about her. It made me nuts when Marty basically laid all this at her feet when he was planning to take off to the gold coast with his family. I know it's a vote of confidence that she can handle the business side, but does anyone seriously think that the cartel would be all "well, it's okay if Ruth is running the money laundering operation now - we don't care where the Byrds are!" Hell no! They will torture her again, or even kill her or her family because there's no way they won't think she's not in on it. There's a reason why Marty wants to be untraceable and to put Ruth in that position was really irresponsible and, I thought, showed how little consideration he really gives Ruth.
I'm okay with Wyatt's anger about Ruth's confession. At first I was kind of annoyed by the "ghost of Wyatt's dad" making appearances to Wyatt, but it gave some insight into how he saw his relationship with his dad. And like Ruth's situation, it's the family he had and it's the family he loved. He knew parts were fucked up, but when you look at things like the situation at school (Wyatt being underestimated because he's a Langmore - Mizzou is out of reach for him simply for that reason) it underscores how isolated they were from everyone else, so I get that you love the ones you're with (especially when no one else will give you the chance). I feel badly for Wyatt because the most important person in his life was killed by the second most important person in his life (and the only one who really has his back).
I think there are some interesting parallels with father/child relationships - you've got Ruth and Wyatt, but there's also Jonah, following in his dad's footsteps, laundering money too (and how fucked up is it that Wendy asked him to do some more, "just this once"? - the Byrds aren't much better in the parenting department than the Langmores; they're just a little more presentable about it). All these children wanting their fathers' approval...
I have to ask this question because we obviously missed something: I thought they wanted the Snell's land to build the casino, isn't that right? Wasn't that part of all the back and forth this season? And now Zeke is (shudder) living under Darlene's care. So what was the point of all of that if the casino is a riverboat now? Is that supposed to be the segue for the casino on the Snell's place? That ties into my biggest complaint about the season - it seemed kind of all over the map. I do understand that these types of stories have a lot of moving parts, but we have the cartel, the Snells, the Byrds, the locals, the Feds and now the mob. I think if they're going to bring in so many different factors the storytelling needs to tighten up a bit. Breaking Bad was masterful at that stuff, but this show doesn't seem to be as artful at juggling all these bits and pieces.
