i've already stated frank is a female rachel. he's easily manipulated and boogie basically turned frank into a copy of him when frank didn't want to be anything like froogie.
dan can reel in his former teammates easier than expected. if dani stays she'll spill the fact that the fight was an act to save them both. shane can buy into that easily and he loves the ideas of fake fights b/c he keeps wanting one. if brit goes then dan is ian's number two by default, he hates frank, joe and him hate each other, jenn wants nothing to do w/ him, and dani and him don't mesh.
frank is really dense when it comes to this game. joe and jenn brought up dan's i will rat you out comment towards ian to him and he shot it down. frank may not trust dan but he can't play in the next two HoH's. that makes taking a shot to get him out irresistible.
dan really only has to worry about joe. jenn might not pull the trigger especially if the DR gets in her ear to keep dan in. they'll want to roll w/ dan and frank, just like they wanted brit and ian to roll w/ frank until dan flipped their script. a shane HOH could be a small problem.
brit and ian betrayed dan throughout the week. brit was doing it for about two weeks. they threw him under the bus and brit did it to deflect attention off of her and to protect ian. when they were asking about the rat she pointed to dan's bed according to frank.
dan seriously considered throwing the POV, but ian made comments that made him reconsider. he was like i don't want anyone throwing the competition thinking i'm going to use it, i'll only use it in this perfect scenario.
