Best case scenario(s) -
Casey OR Jordan win HOH
put up Ronnie and Jessie
If Jesse gets off through POV, put Russell up (or Nat if Russell takes Jessie off)
If no one takes Jessie off, he stays up and everyone will vote Ronnie out anyway.
If Ronnie wins POV and takes himself off, put Russell up against Jesse. Most, if not all, would vote for Russell to go.
I will be praying hard tonight!
