I have been having some thoughts about the Duo Twist and the FT, golden key and possible DPOV.
I think production wanted to ensure that somehow there was one Vet and one Rookie (I don't like the term Noob LOL) in the final, or at least in final three. If Rachel had not won Veto, then probably Rachel would be going home. Jordan would have the golden key, not be able to play for HOH, or Veto or be nominated, but she gets to vote!! Also safe from Nomination at 4. Then her DPOV would come into play at final 4, to ensure she decided who went home.
This scenario also works with a Rookie, Adam, hopefully being kept this week.
(It will be interesting if the Golden Key rules apply, because then Adam could not play in HOH, neither can Porche, and it will be Rachel and Jordan against only Kalia. Adam could also not play in Veto if the GK rules apply, but he gets a vote.)
GO RACHEL AND JORDAN AND ADAM!!
