If Frank wins, I think he might put up Ian. He was doing a lot of talking when they want back live inside the house. Right after the POV he was yelling at him, "You made the wrong decision!"
Frank has no allies in there and he is going to have a target on his back every week. His best move if he wins HoH would be to put Ian side-by-side with Dan. He knows they are both coming after him anyhow, so it's not like he is making a new enemy. And this way he can get one out. He can then try to work the rest of the house to try to get them to ally with him -- as a strong competitor who will carry them through.
I love how they made the second HoH a memory game. It was as if they WANTED Ian to win. The minute I saw that, I was like, "He is going to turn on the photographic memory now." I love Ian, and I think he has played a good game, but it hasn't been a perfect game. He duped Boogie and Frank by lulling them into a false sense of, "Ian is a harmless kid." But he should have played it all the way through and not said a word to Boogie on his way out the door.
I get the sense the house is going to turn on Ian. Dan kept talking about, "I am taking a lot of heat for this kid. I hope he realizes. ..." It's too bad. I want him to win. Either way, he has to be the odds on favorite for the $25K for America's choice, right?
