And so in this part of the story it makes sense that he's turning on her, because he has to. But the writing last week was so bizarrely distracted that they seemed to be having this fight, from another direction, for no reason, and none of this arc of Bill's crown being heavy really makes sense at this point, because the seeds were not sown early and they were not sown correctly. In practice he's still just attacking her for no reason, but at least you can see the narrative intent behind it.
Nan: "There are Glamour Squads [!] all over Shreveport. If anything leaks remember the Civil Rights movement, sweeping social change, inevitably accompanied by violence and the appearance of chaos, yadda-yadda. That is the spin we'll give it."
Bill: "Spin does not mattah now!"
Nan: "Spin always matters, queerbutt."
Bill: "You are not in charge anymore!"
Nan: "Um, yeah I am. Whining doesn't make any of that change."
Bill: "Ah am goin' to tattle on yew to the Authority! [Spurious conjectures and outright lies which, maybe they were true before the preceding episodes were shot, but they make zero sense now.]"
Nan: "Whatever, dude. I'm out. One more vague mention of the 'factions' I'm balancing in the AVL and then peace."
Bill: "Ah should ask why you continue to mention those factions, as they may well be central to our continued storyline. But Ah shall not! My incomplete information is more than sufficient, as is usual!"
Nan: "What part of stop making yourself a political liability do you not get?"
Bill: "Not one parcel, ma'am. Not one jot nor tittle do Ah grasp. Now, we are going to storm that Emporium and murder a bunch of humans. Murder them. Ah dare you to contradict me!"
Nan: "God. At least when Sophie-Anne was asking for it she was adorable and dizzy. You're just being a dolt."
Bill: "It is mah pride! And mah duty!"
ROOKIE REVISITED, REMIXED & REMASTERED
Eric: "So, we're still dating, right? Nothing's changed?"
Sookie: "No, lots of things have changed. Like you're Eric Northman again instead of the class bunny rabbit I brought home for the weekend. For example."
Eric: "He's in here. Look at my bunny-rabbit eyeballs."
Sookie: "But like, dating you know would be like a real person? And that didn't work out with me so well two weeks (54 weeks) ago, when I found out Bill nearly got me murdered to seduce me and was keeping dossiers and shit. Which, not for nothing, but that kind of behavior wouldn't be that surprising from you on like a regular Wednesday."
