I posted my speculations the other night on another board. here's what I thought before the jury questioning:

I think that Ryan gets more than one vote. I even think that there is an outside possibility that he wins.

I don't think that Adam has this as much in the bag as he thinks. Ryan needs to work on an answer as to why he should get the money since he had been evicted once.

Sharon will probably ask him about the head nod between him and Adam when she was evicted. Ryan's answer to that could change some votes.
If he tells the truth (last minute decision and each guy took a hit) then I think Sharon will accept his answer and vote for him.
That would also result in exposing Adam's part of the deal to Sheila. I can see her working to turn the votes because of it. Adam is going to come out looking the worst IMO if the deal between them is exposed. Especially with the spineless comment thrown out to him by Chelsea when she was evicted.

Plus I think that Josh just likes Ryan better anyway.

I can see Ryan getting votes from Chelsea, Josh, Sharon, pretty easily.
I think he gets Sheila's vote if she finds out. That would make it four votes. enough to win.

I'm pretty sure that Natalie and James will vote for Adam. Matt I'm not sure of. I need to refresh my memory about him.

I still pretty much think this is what will happen IMO.

Based on the reactions of Ryan and Adam after the questioning, I think that Ryan just might have Sheila's vote too.
At first I didn't think that Sheila would vote for him because she is hoping that he will give her some of the prize money---after all she is a 46 year old single mom.
If Sheila saw the entire HoH comp and saw that Adam threw it to Ryan then she realizes that Adam never had any intention of taking her to F2. She will take that further and think that he has no intention of giving her any money either. I can see her being pissed off enough to not give Adam her vote.

Matt is still a tossup in my mind but I think he will vote for Adam if he believes that Adam will take him to party in Vegas.
