I know people have been loosely saying that Kim probably made final three deals with everyone, but the deal she probably made with Alicia and Christina must be very convincing to them. I suspect that Kim told them that she plans to go to the end with them, and when it comes down to final 6, she, Chelsea and them will turn on the other two. It's also interesting to note that the three of them all voted for Tarzan. I just can't see any other plausible explanation as to why Alicia and Christina are so complacent with supposedly 5 and 6. Alicia is much smarter than it seems and she is a rather surprising thinker. I think she realized that whatever offer Kim made her was worth it. Also when Kim received the second vote, she made eye contact with Christina. I think this side deal she has going with them would explain why she hasn't played the idol. She probably told them about the idol like how Rob told his bimbos (off screen). It may also tie in with the foreshadowing of Alicia killing Kat.
I think i'm stating the obvious, but there's no threads with this title yet
