Rachel and Brendon were up before the others and held a strategy seminar in the back yard, mostly to do with persuading Britney, who they see as an increasingly powerful figure, that Kristen and Hayden are an item.
It's because Britney has no alliance anymore, so she is a free agent. I seriously think she's a great contender to win now, I think she'll definitely be up there in the late jury stage.
I think I'd quite like to see Rachel win HoH next week and put Kristen and Hayden on the block. Send Kristen home, exposing The Brigade, then Annie comes back in the week after, wins HoH and puts Rachel and Brendon on the block.
