Annie quietly comes out to Ragan. "I actually have a girlfriend," she whispers. He hugs her happily, and now they have a secret opposite-sex bond of same-sex love. If they have sex to celebrate, we don't see it..
Brendon and Rachel soak in the hot tub together and talk about science and education. Watching from across the yard, Hayden seems to disapprove of this showmance in the making. Or maybe he's just jealous because he's supposed to be having a showmance with Kristen and she's not getting any screen time at all.
Hayden and Enzo, meanwhile, start an alliance of their own, apparently because they both seem to like working out. Although they have decided it's too hot to work out right now. Enzo rattles off a few names of other potential allies, who are all dudes. Try to look surprised. Their first recruit is Matt, for his brains; and Lane, ostensibly because Enzo knew where he was during the blackout so they know they can trust him. That's really all it takes? Matt DRs that he's leery of getting into an alliance this early, but calls this "the strongest alliance in Big Brother history." In case you've forgotten who Matt is, he's the one in Mensa.
Enzo is already up in the in the HoH room with Hayden and Matt, calling himself the "organizer" and "mastermind," and when Lane joins his little mafia (his word, not mine), he bestows nicknames on everyone: the Beast (Lane, who Enzo wants for his muscle), the Animal (Hayden, I guess because dude needs a haircut), and the Brains (Matt, because whatever). As for himself, Enzo calls himself the "Meow." Well, at least nobody can accuse him of giving himself the coolest nickname. They decide to be "The Brigade." Ugh, I hate it when alliances give themselves names. Especially when they do it before actually accomplishing anything. It's like bands who think up album titles and pose for photos before having anything like songs. But at least now Hayden knows who to put up: Brendon, because he's a saboteur suspect; and Rachel, because she's closest to Brendon. Enzo seems to think they've already won. Dude, wait for one eviction before you declare victory, will you please?
