Bill decides to piggyback on Eric's scheme to bury Russell alive with one of his own to bury Eric alive in an adjacent hole. But the details of his plot are so skimpily given that a viewer could be excused for not fully following that Bill put a glove on his hand so he could put a silver handcuff on Eric and weaken him enough to push him into the cement. The final reveal that Pam took out the assassin Bill called, allowing her to jump in the concrete and save her Maker, would have been much better actually portrayed onscreen, both in terms of clarity and drama. We could have done with more of this plot and less of so many others. I care much more about the real natures of Eric, Bill, and Sookie than say, Arlene's baby or Crystal.
Last season, Bill was far too one note and there never seemed to be any consequences for his actions. Ball appeared to be painting him as The Good Guy, which left Eric as The Bad Guy. This season, there has been welcome shading in both characters, so that they are now simply Bill and Eric, both with flaws and virtues. Bill's willingness to lie about anything he knows that Sookie will find unpalatable has grown increasingly evident, as has his attraction to violence. We watched him deliberately use sexual violence to express his anger at Lorena, which made his denials of his own complicity in their violent history very suspect. In the finale, we watch him gleefully mock Russell as he's helping bury the king alive. Eric's personal history makes his anger understandable while Bill's joy in twisting the knife seems more like a bursting through of something he tries hard to bury, but never quite can. And that something makes his attempt to murder Eric and Pam much more problematic than he admits to Sookie.
Sookie spends the episode finally admitting she is very angry at Bill and doesn't trust any of the vampires in her life. It's long overdue and unfortunately still doesn't quite ring true. The scene where Sookie taunts Russell with the loss of Talbot seems a little too cruel for what we've seen of this character, unless we get some hints in the near future that her faery heritage is not all sweetness and light. I was also puzzled about her reaction to Bill confessing that he's just taken out Eric and plans to kill anyone he deems a threat to her in the future. Sookie is surprised at Bill's action, but is easily swayed into thinking Bill's murderous plans are a testament to his love for her rather than showing her he's a less fun version of Franklin. Given that she pushed Bill aside to rescue Eric just hours earlier, I would expect her to be more upset at his death at Bill's hands, and given that she no longer trusts Bill implicitly, I would expect his murderous plans to look less romantic to her and more frightening.
