Male-ing It In
Adam took the second part of the HoH competition, so unless something very weird happens in the next 20 hours, we're going to have only the second all-male Final Two ever on BB (the sense that men are "threats" tends to make it less likely that they get farther in the game). There's one explanation for how it worked out this way: guys dominated the HoH competitions this year, with Sheila and Natalie the only women to win solo HoHs.
In fact, Ryan and Adam will have held 5 of the 8 solo HoH weeks between them, which is an awfully good way to keep an alliance together, especially when your best female allies are the only women winning those comps. It's a far cry from the feeling back when Ryan first won Head of Household, when the consensus was that it was going to be a nice bonus for a guy who had been in almost constant trouble during his early days in the house (thanks to the revelation of the Jen relationship and the partnership with the unpopular Allison), but probably wouldn't do much for him in the long run. He then survived the re-entry of James, the sort of bad break that has ruined a person's game life in the past. We never could have guessed then that Ryan's survival of that week, half a season ago, would be the last true hurdle between him and the final two.
But Adam will win, I expect. And since he's unemployed, it might even be for the best. Again, that would be an amazing story considering the early reaction to Adam in the house and among many fans was "ewwwww."
