Sam comes into the bar and Arlene acts all nervous like he's going to beat some meth dealers to death first thing, and hop-scoots over to save his hangover from the TV. Specifically, a news report about Russell's compound being completely empty, its many gay servants having vanished into thin air leaving only black wifebeaters and tight jeans in their wake. Everybody is scared of him, including Terry, or maybe Terry's just being weird as usual, but not including Tommy, who loved watching his big brother beat up a whatever-they-are, and even makes a "hair of the dog" joke that only the two of them can understand. Sam finally tells everybody to stop walking on eggshells, and that he's already talked to Lafayette and Calvin is fine: "So pretend you're all normal?"
Ha! Fat chance. Holly Cleary presents him with a little vial of black cohosh, which he mistakes for pot, and she explains sunnily. "Brings down your testosterone levels. For your rage? You obviously have a problem." He asks if she's got anything for "nosiness and bad boundaries," and she says it's just her hobby, as a Wiccan, to make remedies and tinctures and things for people. (Arlene staaaaares.) Sam tells her the only rules for Merlotte's are A) No dancing and B) No religion. (I'm assuming before Jane Bodehouse got her groove back there was just one rule.)
(And yes, in this very Carmen Sandiego culturally-aware Rachel Getting Married episode, that sticks out as a "Wicca is a real religion" PSA, which it is on one level. But there are about three reasons we can't see yet why this needs to be in place, so consider that line to be Sam telling you, the viewer, that we should just stop worrying and consider Wicca a real religion from here on out. Not that it isn't, just that on your supernatural TV programs sometimes it is and sometimes it isn't, but in this case it's just a religion like any other. And by my count, the only sane one they've shown to date.)
Tommy is troubled by Sam's admission that he didn't kill Calvin Norris -- after all, even Arlene was being more respectful of him -- and Sam tries to explain the difference between respect and people thinking you're a psychopath. Surprise, Tommy does not see the distinction: "All I know is, I was proud of my big brother last night." Sam points out that Tommy is an idiot, and leaves.
Arlene drags the trash out back, and Terry chastens her, stubbing out his cigarette: "Secondhand smoke, bad. You carrying a heavy load, bad-bad." Arlene starts crying and can't talk, and sweet Terry goes, "Are you spotting grayish tissue, having side cramps, or experiencing a dull, consistent ache in your lower back?" She still can't say anything. Please don't let me down, Fowler. You're getting more interesting every episode. He grabs her and says he's going to be a wonderful daddy and she shouldn't worry about that anymore, and that's just too sweet to bear, so she totally comes clean: The baby isn't his, it's Rene's, and it's evil, and she wants to get rid of it.
