I don't think Robert will use it once again unless he put's Jun up and takes Jack off, that way still protecting the other 2 stooges, Nathan must go, who I think is next on everyone's shopping list now.
Interesting to learn how Alislut is now putting the word around about Jack to others that she thinks he's throwing the competitions. She obviously feels no need to have Jack on board in the same alliance now & I believe Erika is in the same position as Jack .
Makes me wonder if she really would stick to her word in a time of crisis and choose not to nom Justin if the situation arose, after all Justin is a major threat to her winning and visa versa and the option to choose Justin will become a reality sooner or later.
