After the ads, Allison makes a tearful confession about Jen and Ryan to Neil and Joshuah, the latter of whom starts wondering who else in the house knows each other from before. So he gets the idea of making everyone swear on a Bible as to whether or not anyone else knows each other, which he thinks is sure to work because if you lie while swearing on the Bible you're sure to go to Hell. I don't find it ironic that a gay guy is saying that, but I'm sure there are CBS viewers who do. The houseguests gather in the living room and pass around the good book, all swearing in turn not to have known anybody before coming in. Not everyone is convinced. In fact, Alex and Matt decide afterward to form an alliance, swearing on their fathers. Matt DRs about what a big deal that is for him, and how he'll never invoke his father in this game again. Because it's out of the way in the first week, I guess. They then bring their girls into the alliance (they're happy to go along, which might have been complicated for the guys and Alex's dad if they hadn't), and resolve to win HoH or PoV every other week. Good luck with that, guys. So with that out of the way, they start talking about who to nominate for eviction. The first candidates? Jen/Parker and Ryan/Allison, of course.

Later, Allison complains to Sheila, who tells her to hang tough; nothing could be worse than being with Adam, after all. Sheila jokes that they'll get Allison revenge by pretending to be longtime lesbian lovers now. Oh, this can only go well.

The first person they tell is Joshuah, who's completely blown away. But he seems to buy it, and, moreover, runs off to the storage room to tell Neil. Then Alison and Sheila tell Chelsia, who is even more credulous. Allison congratulates herself on a "very big power move." That phrase…I do not think it means what she thinks it means.

Next morning, Allison jogs around the back yard while Adam yells at her around his cigarette and Sheila complains to Parker about Adam. While she's doing that, Alex provides this season's first hilarious "falling out of the hammock" shot in the background, and then DRs that Sheila is getting on his nerves with all this. He and Matt defend Adam to Sheila, and Adam comes over yelling at Sheila, causing everyone else to clear out. But not out of earshot, because Sheila just screams at him and storms inside, in front of everyone. "That might have helped you," Alex obviouses to Ryan and Jen afterwards. And Sheila goes and sobs uncontrollably on a bed. Not her bed, of course, because she has to sleep in a sleeping bag.
