Well, I guess we will have to see how this plays out for Zach in the long run, but I think it was a huge mistake for his not to use the POV during the fast forward episode. If he had, he would have forced Dick to replace whoever he took off with Daniele. Then whoever was removed and Zach could have voted her off and broken up that damn D and D stronghold. I really don't see the benefit of staying loyal to those two at this point. They obviously have no problem stabbing people in the back to advance their game, but expect others to stay loyal to the end.
I think it was a poor decision on Zach's part because at that point, D and D are the only alliance left in the house (Jess was already voted out). I just don't understand. Get rid of Dani, and then it just two of the most hated houseguests and Jameka left to contend with.
