Daniele and Dick are on the block. So, let's walk through it.
Daniele, Dick, Zach and Jameka get to do the POV.
If Zach wins, nominations stay the same and Jameka votes off Daniele.
If Jameka wins, nominations stay and she votes off Daniele.
If Daniele wins, she takes herself off, Jameka goes up and she goes home.
If Dick wins, he takes off Daniele, Jameka goes up and she goes home.
So, its 50:50 of either Jameka going home or Daniele going home.
