Well, that was sure interesting! I actually think that Pandora's Box was, in fact, game changing. Here's my theory ---> Kevin saw Nat's true colors while he was locked inside the box. (remember what he was saying about her) Michele was making a lot of sense when she was talking to him about keeping Jeff. He is "cock-blocking" Nat because he doesn't trust
her, and
not because he is afraid the other HGs will talk to her - he just wants her to think that. He wants her to vote for Jeff to go, and for Michele to vote for Jeff to stay - that way
he will have to break the tie, and he can send home whichever one he decides, and it will be
his decision. That way Kevin can get Jeff to evict Nat, and he will keep his hands clean. If Michele and Jeff gave it some thought, they will convince Kevin that with Nat in the JH she will rally the votes for him in the end. Each one of them (Jeff & Michele) should separately try to convince Kevin that
he is their pick for F2. It
could work.
