I believe Luke will realize that he was in with the wrong crowd and quickly shift over and won't bitch as much, and then the public will love him once again because he can get away with it.
I also believe that Dale will fade much more into the background than before.
Rex might begin to become arrogant due to the fact that he survived an eviction against his enemy, picking fights with everyone since he knows he had the public support.
..and Rebecca will still be bitching alone, unless she adopts one of the new girls.
