Zoom up to Nicki's room, where she's got Raymond making the bed with her by singing a song with him set to "Michael, row the boat ashore." Raymond looks like he's enjoying this. Barb comes in and says hi to Nicki and Raymond, and from the bathroom, Wayne yells, "I'm here too!" The boys are sent to go visit with Teeny while Barb tries to negotiate a new schedule with Nicki. Barb's bright idea: "I thought you could look at your calendar and give me an estimate of your cycle." This way, they can schedule Bill for the nights Nicki's likely to be ovulating. Nicki asks her, "Why don't we just do it like we used to: keep to the schedule and give him to me on an additional basis?" Barb pushes for the wonders of regimented time, and Nicki hems and haws about how she'd rather have Bill come home the minute her basal temperature jumps. Barb protests, "Yes, but you only ovulate two days a month." Nicki says, "You're so persistent." Barb twigs to the subtext and promptly apologizes, adding, "I guess I'm in organizational overdrive today." As the two of them pull up Nicki's comforter, Nicki notes, "You do that when Bill goes away." The two of them then have this subtext-loaded conversation:
Nicki: There's been something I've been meaning to tell you. I was wrong about Bill.
Barb: Wrong?
Nicki: He's not seeing a fourth [wife].
Barb: Oh, I never thought he was. What gave you that idea anyway?
Nicki: Oh, little things. He wasn't where he said he'd be, leaving the house at odd hours. And it turns out I just had my signals crossed.
Barb: Well. That's easy to do.
Which, when filtered for passive-aggressiveness, comes out to this:
Nicki: By the way, I'm on to you and Bill.
Barb: You think so, Laura Evil Wilder?
Nicki: Yeah, more or less confirmed it, Boss Lady.
Barb: With what evidence, Agatha Nicki?
Nicki: A little thing I like to call star-sixty-nine. Plus your kids squealed.
Barb: It's all circumstantial, I'm not apologizing for it, and I don't plan to quit.
And then we find out that Nicki's coital instructions to Bill were a dry run (so to speak), as she's secretly taking birth control pills. I'd say she's trying to lure Bill into her web via sex, but given how cool he is toward her compared to the other two, that ploy seems really sad and misguided.
