I hope something changes either within or against the Brigade Alliance because after next week, if two of them aren't nominated, their alliance will have a majority vote, given that Kristen will side with whatever her & Hayden benefit from. If Kristen is to vote with Hayden and the Brigade, whoever they want out WILL be evicted, because they've got four votes, if the other four voted opposite, it's Matt's call, who would side with his brigade.
Even though Brendon/Rachel are the obvious choice, I don't think it's time to split them up. The Brigade needs to be split up very soon, otherwise it's going to be a very predictable game all along. However, I'm still honestly surprised these four are still together. Also, since Sunday's episode has been broadcasted, Kathy & Andrew have been nominated. If Kathy was to be evicted, we would be down three women, with three women remaining, as Rachel, Britney, & Kristen are all against each other.
