I personally wouldn't want to see Ted or Jan win, but anyone else left would be acceptable.
Clay has a good strategy, and has been shown to be playing the game full-on, with no guilt. While it's not my personal choice, I respect him for it as much as I did Richard. They're doing their thing, and doing it well. If he weren't such a horny wierdo, I might have a little more like for him.
Brian sees himself as king of Briania, but I think his kingdom is about to split on him. The only one he doesn't control is Jake, and Jake's going to get smart this week and give Helen and Jan the full-court press. Hell, he's leaving in 3 days, might as well shake things up as much as he can. Beware of the man with nothing left to lose.
Helen has actually played a pretty good game until now, but she needs to get some "me time" and calculate her odds of winning with each alliance. It's the only way she'll be able to see it clearly. If she stays caught up in everything going on around her, she won't make the smart choice.
