If Dustin votes to keep Eric he will have a huge target on his back...as he will have gone back on his word to everyone. Well, not that that matters in this game.
Dustin "promised" ED this morning, that he would vote Eric out.
I firmly believe at this point, that Dustin will go back on that "promise" and will vote out Kail.
When that happens, Dustin will lie again and say he DID vote Eric out.
That will make it another eviction with a vote that can't be accounted for.
Everyone will whisper, "who was it? who was the 4th vote for Kail?"
The suspicion will then fall on Jen, Zach, or ED.
and the game continues....
