Nate moving to the darkside was a bad move imo. They make it work narratively, but he was probably the funniest character in the Richmond locker room, and a great deal of that comedy came from his diffident charm. The whole spitting in the mirror villainy thing just doesn't do it for him as a comedy character. It's the latest in a series of moves that takes the show further from comedy and more towards just lacklustre and silly drama. He'll probably get a redemption story, but I think it might come too late to salvage the joke.
