Jeff said one time that shaking his foot was his way of rocking himself to sleep.
I think Nat & Kevin are really playing "the game" - aren't they supposed to lie and con their fellow HG's in order to advance themselves? Jeff has been acting like he is enrolled in the BB entitlement program. During the cast intros he said two very telling things: 1) that he was not going to rule out a showmance to advance himself, and 2) that he was "pretty", and that should work in his favor in the game. I think he is as Alpha as Jessie and Russ - he just manifests it differently. Michele has used her superior intelligence throughout the game - I don't know anything about drugs, but didn't Jeff say something to her today about taking a tranquilizer? I think she is beginning to realize that J & J are going to screw her over. They lied to her about Kevin & Nat, and now she smells the proverbial rat, and sees the handwriting on the wall - and she is right! She needs to win HOH - but even that won't help because she won't be able to play in F4. Her only shot may be to work with Kevin to vote Nat out. That would be a very cool move, and keep the game interesting to watch for the next week. Jordan, poor dear, has 7 brain cells and only 4 are functioning at any one time. (I knew someone in WVA who used to use this phrase all the time:) She just ain't fetchin' it.
Kevin is smart - he should align himself with Russ and Michele and vote Scrappy back to Jessie and Lydia's loving arms. That would be a hoot all the way 'round.
