I'd like to think this show helped win him that.
I don't think this is going to be a Fuck You ending. At least not as far as the investigation goes. Their lives are such a fucked up wreck anyway that even a victory is depressing. I think they'll expose the whole family, on up to the Senator, in a way can't be covered up. No silly twists that cheapen the whole thing.
When it's all over though, it'd be hard to say which one is going to eat their gun first. Rust seemed to be spelling out his intentions to check out at the end of all this. And Maggie sure as hell thinks Hart is ready to.
Be careful what you get good at. Christ what a fucked up show.
