Adam and Ryan work through the decision.

It was a long night for the boys trying to decide if they should keep Natalie or not. At first Ryan talked to Adam for a while and decided that Sharon has never done anything for them and that Natalie would have stuck with them to the final four. They feel that Sheila is just trying to keep Sharon so she will have help in getting the boys out and if Sharon leaves, Natalie will make the house 3-1 and Sheila will be next to go. They reasoned that Natalie never did anything to them or give them any reason to believe she would have have either. So they agreed they should follow their hearts and take the possibly harder road of getting Sharon out even though Natalie may be a tougher fight in the end. But they also said that they should go ahead and get Natty out before Sheila if the opportunity is there.
So they called Natalie outside to tell her the good news and she was obviously very happy and relieved. They gave her their word and asked they she didn't say anything to the other girls and to just act like she thinks shes going home.
Later, Adam went upstairs to talk to Sheila and after a few minutes of listening to her he wound up fessing up to the fact that he and Ryan were planning on keeping Natalie. Unsurprisingly, she flipped out and started going off about it and then asking, demanding, and begging that they not do that. She went over all the reasons she wants her gone, Stating also that Adam needs to think about who he can really beat when its down to the final 3 and theres a bunch of competitions between them for the final 2. She stated Natalie's the bigger threat and that they should get rid of her then Sharon then Ryan. She mentioned that if Adam can't get Ryan to vote Natty out, then just make sure Adam does and then she will happily get the blood on her hands. She requested that Adam go and bring Ryan up to the HOH to talk. Adam went to go get him but at first Ryan refused because he didn't need to hear all the same crap all over again and he feels anything she says is irrelevant because she only wants Sharon here for her own safety and that it doesn't really have anything to do with the boys.
After Ryan got out of the DR he finally agreed to go talk to her and it wasn't pretty. Sheila did her usual freaking out about it tried to talk the boys into doing things her way. Ryan didn't really budge and so she kept working on Adam. At end of the conversation, Sheila made a comment to Adam that rubbed him the wrong way and Adam kind of snapped and somewhere in his comeback he managed to call Sheila a "f*cking b*tch"!! That effectively ended the conversation. Sheila angrily kicked Adam out of the room( and of course Ryan went with him.)
Shortly after that, Adam and Ryan were talking again and apparently some of what Sheila has been slamming into his brain starting having an effect. He began saying that maybe Sheila was right and it would be best get Natalie out now to which Ryan countered with the usual argument and they seamed to still be settled on Natalie staying by the end of that talk. Adam was talking about how sending Natalie to the sequester house would effect the jury votes but Ryan made a counter point that it doesn't really matter because they will be the final 2 in all likely hood anyway so what difference would it make if they had "pleased" them or not by sending Natty? They would be equally happy or mad at them and would still have to make a choice anyway. That is a very good point and it was driving me crazy waiting for one of them to realize that.
However, When Ryan was in the DR the last time he told them he was having a hard time making a decision and they told him to come back in there in a little while and they would run through scenarios with him to help him out. When he went back in to do that, they must have played the scenarios out in such a way that it changed Ryans mind because suddenly Ryan, who was the most adamant about keeping Natalie, was saying that they should make the vote 1-1 and let the blood of getting Natalie out the door be on Sheilas hand. To which Adam happily agreed.
So when the dust settled it looked like the only thing that had really changed was that they were going to make Sheila do the dirty work instead of them. Theres still a little time for things to change so we will see.
