She made 1 really dumb game move this season. She didn't use the Power of Veto to save Ramses and get Paul on the block. She knew that Paul really wanted her out and maybe if she would have nominated Paul Josh would have got out.
If they don't win HOH they need to both take the temptation. One wins for safety and the other loses (preferably Cody) so they're guaranteed veto. It also forces HOH to make real noms because if Cody wins POV then the week has to continue
